Microbiota profiling in esophageal diseases: Novel insights into molecular staining and clinical outcomes. Comput Struct Biotechnol J 2024; 23:626-637. [PMID: 38274997 PMCID: PMC10808859 DOI: 10.1016/j.csbj.2023.12.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 12/22/2023] [Accepted: 12/23/2023] [Indexed: 01/27/2024] Open
Abstract
Gut microbiota is recognized nowadays as one of the key players in the development of several gastro-intestinal diseases. The first studies focused mainly on healthy subjects with staining of main bacterial species via culture-based techniques. Subsequently, lots of studies tried to focus on principal esophageal disease enlarged the knowledge on esophageal microbial environment and its role in pathogenesis. Gastro Esophageal Reflux Disease (GERD), the most widespread esophageal condition, seems related to a certain degree of mucosal inflammation, via interleukin (IL) 8 potentially enhanced by bacterial components, lipopolysaccharide (LPS) above all. Gram- bacteria, producing LPS), such as Campylobacter genus, have been found associated with GERD. Barrett esophagus (BE) seems characterized by a Gram- and microaerophils-shaped microbiota. Esophageal cancer (EC) development leads to an overturn in the esophageal environment with the shift from an oral-like microbiome to a prevalently low-abundant and low-diverse Gram--shaped microbiome. Although underinvestigated, also changes in the esophageal microbiome are associated with rare chronic inflammatory or neuropathic disease pathogenesis. The paucity of knowledge about the microbiota-driven mechanisms in esophageal disease pathogenesis is mainly due to the scarce sensitivity of sequencing technology and culture methods applied so far to study commensals in the esophagus. However, the recent advances in molecular techniques, especially with the advent of non-culture-based genomic sequencing tools and the implementation of multi-omics approaches, have revolutionized the microbiome field, with promises of implementing the current knowledge, discovering more mechanisms underneath, and giving insights into the development of novel therapies aimed to re-establish the microbial equilibrium for ameliorating esophageal diseases..

Rennie O, Sharma M, Helwa N. Colorectal anastomotic leakage: a narrative review of definitions, grading systems, and consequences of leaks. Front Surg 2024; 11:1371567. [PMID: 38756356 PMCID: PMC11097957 DOI: 10.3389/fsurg.2024.1371567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 04/22/2024] [Indexed: 05/18/2024] Open
Abstract
Background Anastomotic leaks (ALs) are a significant and feared postoperative complication, with incidence of up to 30% despite advances in surgical techniques. With implications such as additional interventions, prolonged hospital stays, and hospital readmission, ALs have important impacts at the level of individual patients and healthcare providers, as well as healthcare systems as a whole. Challenges in developing unified definitions and grading systems for leaks have proved problematic, despite acknowledgement that colorectal AL is a critical issue in intestinal surgery with serious consequences. The aim of this study was to construct a narrative review of literature surrounding definitions and grading systems for ALs, and consequences of this postoperative complication. Methods A literature review was conducted by examining databases including PubMed, Web of Science, OVID Embase, Google Scholar, and Cochrane library databases. Searches were performed with the following keywords: anastomosis, anastomotic leak, colorectal, surgery, grading system, complications, risk factors, and consequences. Publications that were retrieved underwent further assessment to ensure other relevant publications were identified and included. Results A universally accepted definition and grading system for ALs continues to be lacking, leading to variability in reported incidence in the literature. Additional factors add to variability in estimates, including differences in the anastomotic site and institutional/individual differences in operative technique. Various groups have worked to publish guidelines for defining and grading AL, with the International Study Group of Rectal Cancer (ISGRC/ISREC) definition the current most recommended universal definition for colorectal AL. The burden of AL on patients, healthcare providers, and hospitals is well documented in evidence from leak consequences, such as increased morbidity and mortality, higher reoperation rates, and increased readmission rates, among others. Conclusions Colorectal AL remains a significant challenge in intestinal surgery, despite medical advancements. Understanding the progress made in defining and grading leaks, as well as the range of negative outcomes that arise from AL, is crucial in improving patient care, reduce surgical mortality, and drive further advancements in earlier detection and treatment of AL.

Early postoperative systemic inflammatory response as predictor of anastomotic leakage after esophagectomy: a systematic review and meta-analysis. J Gastrointest Surg 2024; 28:757-765. [PMID: 38704210 DOI: 10.1016/j.gassur.2024.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 01/22/2024] [Accepted: 02/03/2024] [Indexed: 05/06/2024]
Abstract
BACKGROUND AND PURPOSE Postesophagectomy anastomotic leakage occurs in up to 16% of patients and is the main cause of morbidity and mortality. The leak severity is determined by the extent of contamination and the degree of sepsis, both of which are related to the time from onset to treatment. Early prediction based on inflammatory biomarkers such as C-reactive protein (CRP) levels, white blood cell counts, albumin levels, and combined Noble-Underwood (NUn) scores can guide early management. This review aimed to determine the diagnostic accuracy of these biomarkers. METHODS This study was designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered in the PROSPERO (International Prospective Register of Systematic Reviews) database. Two reviewers independently conducted searches across PubMed, MEDLINE, Web of Science, and Embase. Sources of bias were assessed, and a meta-analysis was performed. RESULTS Data from 5348 patients were analyzed, and 13% experienced leakage. The diagnostic accuracy of the serum biomarkers was analyzed, and pooled cutoff values were identified. CRP levels were found to have good diagnostic accuracy on days 2 to 5. The best discrimination was identified on day 2 for a cutoff value < 222 mg/L (area under the curve = 0.824, sensitivity = 81%, specificity = 88%, positive predictive value = 38.6%, and negative predictive value = 98%). A NUn score of >10 on day 4 correlated with poor diagnostic accuracy. CONCLUSION The NUn score failed to achieve adequate accuracy. CRP seems to be the only valuable biomarker and is a negative predictor of postesophagectomy leakage. Patients with a CRP concentration of <222 mg/L on day 2 are unlikely to develop a leak, and patients can safely proceed through their enhanced recovery after surgery protocol. Patients with a CRP concentration of <127 mg/L on day 5 can be safely discharged when clinically possible.

Abstract
In this editorial we comment on the article by Kalayarasan and co-workers published in the recent issue of the World Journal of Gastrointestinal Surgery. The authors present an interesting review on the use of indocyanine green fluorescence in different aspects of abdominal surgery. They also highlight future perspectives of the use of indocyanine green in mini-invasive surgery. Indocyanine green, used for fluorescence imaging, has been approved by the Food and Drug Administration and is safe for use in humans. It can be administered intravenously or intra-arterially. Since its advent, there have been several advancements in the applications of indocyanine green, especially in the surgical field, such as intraoperative mapping and biopsy of sentinel lymph node, measurement of hepatic function prior to resection, in neurosurgical cases to detect vascular anomalies, in cardiovascular cases for patency and assessment of vascular abnormalities, in predicting healing following amputations, in helping visualization of hepatobiliary anatomy and blood vessels, in reconstructive surgery, to assess flap viability and for the evaluation of tissue perfusion following major trauma and burns. For these reasons, the intraoperative use of indocyanine green has become common in a variety of surgical specialties and transplant surgery. Colorectal surgery has just lately begun to adopt this technique, particularly for perfusion visualization to prevent anastomotic leakage. The regular use of indocyanine green coupled with fluorescence angiography has recently been proposed as a feasible tool to help improve patient outcomes. Using the best available data, it has been shown that routine use of indocyanine green in colorectal surgery reduces the rates of anastomotic leak. The use of indocyanine green is proven to be safe, feasible, and effective in both elective and emergency scenarios. However, additional robust evidence from larger-scale, high-quality studies is essential before incorporating indocyanine green guided surgery into standard practice.

Abstract
Background Anastomotic leakage after esophagectomy is a common complication. Laser Doppler flowmetry (LDF) can quantitatively evaluate the blood flow in the gastric conduit. Methods A total of 326 patients who underwent thoracoscopic/robot-assisted esophagectomy followed by gastric conduit reconstruction and end-to-side anastomosis were enrolled. We divided the gastric conduit into zones I (dominated by the right gastroepiploic vessels), II (dominated by the left gastroepiploic vessels), and III (perfused with short gastric vessels). Before pulling up the gastric conduit to the neck, LDF values were measured at the pylorus, the border between zones I and II (zone I/II), the border between zones II and III (zone II/III), and the gastric conduit tip (tip). The blood flow ratio was calculated as the LDF value divided by the LDF value at the pylorus. Results Anastomotic leakage developed in 32 of 326 patients. Leakage was significantly associated with the blood flow ratio at the tip (p < 0.001), but not at zone I/II, zone II/III, and the anastomotic site. The receiver-operating characteristic curve analysis identified an anastomotic leakage cutoff ratio of 0.41 (at the tip). A multivariate Cox analysis showed that a blood flow ratio <0.41 at the tip was an independent risk factor for anastomotic leakage (p < 0.001). Conclusion Anastomotic leakage after esophagectomy was significantly associated with the blood flow ratio at the tip of the gastric conduit. Preservation of the blood supply to the tip via the gastric wall might contribute to a decreased incidence of anastomotic leakage.

Abstract
PURPOSE Anastomotic leak (AL) is a major complication in colorectal cancer surgery and consists of the leakage of intestinal content through a poorly healed colonic wound. Colorectal cancer recurrence after surgery is a major determinant of survival. We hypothesize that AL may allow cancer cells to escape the gut and lead to cancer recurrence and that improving anastomotic healing may prevent local implantation and metastatic dissemination of cancer cells. EXPERIMENTAL DESIGN We investigated the association between AL and postoperative outcomes in patients with colorectal cancer. Using mouse models of poor anastomotic healing, we assessed the processes of local implantation and dissemination of cancer cells. The effect of dietary supplementation with inulin and 5-aminosalicylate (5-ASA), which activate PPAR-γ in the gut, on local anastomotic tumors was assessed in mice undergoing colonic surgery. Inulin and 5-ASA were also assessed in a mouse model of liver metastasis. RESULTS Patients experiencing AL displayed lower overall and oncologic survival than non-AL patients. Poor anastomotic healing in mice led to larger anastomotic and peritoneal tumors. The microbiota of patients with AL displays a lower capacity to activate the antineoplastic PPAR-γ in the gut. Modulation of gut microbiota using dietary inulin and 5-ASA reinforced the gut barrier and prevented anastomotic tumors and metastatic spread in mice. CONCLUSIONS Our findings reinforce the hypothesis that preventing AL is paramount to improving oncologic outcomes after colorectal cancer surgery. Furthermore, they pave the way toward dietary targeting of PPAR-γ as a novel way to enhance healing and diminish cancer recurrence.

Abstract
Anastomotic leakage (AL) remains the main cause of post-esophagectomy morbidity and mortality. Early detection can avoid sepsis and reduce morbidity and mortality. This study evaluates the diagnostic accuracy of the Nun score and its components as early detectors of AL. This single-center observational cohort study included all esophagectomies from 2010 to 2020. C-reactive protein (CRP), albumin (Alb), and white cell count (WCC) were analyzed and NUn scores were calculated. The area under the curve statistic (AUC) was used to assess their predictive accuracy. A total of 74 of the 668 patients (11%) developed an AL. CRP and the NUn-score proved to be good diagnostic accuracy tests on postoperative day (POD) 2 (CRP AUC: 0.859; NUn score AUC: 0.869) and POD 4 (CRP AUC: 0.924; NUn score AUC: 0.948). A 182 mg/L CRP cut-off on POD 4 yielded a 87% sensitivity, 88% specificity, a negative predictive value (NPV) of 98%, and a positive predictive value (PPV) of 47.7%. A NUn score cut-off > 10 resulted in 92% sensitivity, 95% specificity, 99% NPV, and 68% PPV. Albumin and WCC have limited value in the detection of post-esophagectomy AL. Elevated CRP and a high NUn score on POD 4 provide high accuracy in predicting AL after esophageal cancer surgery. Their high negative predictive value allows to select patients who can safely proceed with enhanced recovery protocols.

Abstract
Bariatric surgery has emerged as a highly effective option for individuals with obesity, offering significant and sustainable weight loss outcomes. This surgical approach involves various procedures that alter the anatomy of the gastrointestinal tract, leading to reduced food intake and nutrient absorption. Established procedures such as sleeve gastrectomy, gastric bypass, adjustable gastric banding, and biliopancreatic diversion with duodenal switch have proven track records. In contrast, emerging options like intragastric balloons, AspireAssist devices, and endoscopic sleeve gastroplasty show promise but require further investigation. Numerous studies have highlighted the remarkable benefits of bariatric surgery, not only in weight loss but also in the resolution of obesity-related comorbidities and significant improvements in quality of life. However, successful outcomes rely on a multidisciplinary approach, encompassing preoperative evaluation, patient selection, comprehensive postoperative care, nutritional support, and psychological counseling. Regular follow-up and adherence to postsurgical recommendations are crucial for sustained weight loss and positive long-term results. As bariatric surgery continues to evolve, tailored procedures based on individual needs and ongoing research hold the potential for even more refined and effective approaches. Through this ongoing advancement, bariatric surgery is poised to offer improved patient outcomes, transforming lives for those grappling with the challenges of obesity.

[PMID: 38222119 PMCID: PMC10784652 DOI: 10.7759/cureus.50370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 12/11/2023] [Indexed: 01/16/2024] Open
Abstract
Our systematic review and meta-analysis were designed to evaluate the published literature from 2016 to 2019 on which the role of biomarkers in predicting the anastomotic leakage (AL) in gastroesophageal cancer surgery was investigated. This extensive literature search was conducted on the principles of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), and Excerpta Medica dataBASE (EMBASE) were used to gather the relevant information. No restrictions were made on the type of biomarkers. Wald or likelihood ratio (LRT) fixed effect tests were used to estimate the pooled prevalence to generate the proportions with 95% confidence intervals (CI) and model-fitted weights. For analyzing heterogeneity, the Cochran Q test and I square test were used. The Egger regression asymmetry test and funnel plot were used for publication. In this meta-analysis, a total of 15 studies were recruited with 1892 patients undergoing the resection. The pooled elevated C-reactive protein (CRP) was observed as 13.9% ranging from 11.6% to 16.1%. The pooled prevalence of other biomarkers with AL was observed as 4.4%. Significant heterogeneity was observed between studies that reported CRP and other biomarkers (92% each with chi-squared values of 78.80 and 122.78, respectively). However, no significant publication was observed between studies (p=0.61 and p=0.11, respectively). We concluded our study on this note that different biomarkers are involved in the diagnosis of AL. However, all these biomarkers are poor predictors with insufficient predictive value and sensitivity.

Abstract
BACKGROUND Primary aim was to assess the relative risk (RR) of anastomotic leak (AL) in intestinal bucket-handle (BH) compared to non-BH injury. METHODS Multi-center study comparing AL in BH from blunt trauma 2010-2021 compared to non-BH intestinal injuries. RR was calculated for small bowel and colonic injury using R. RESULTS AL occurred in 20/385 (5.2%) of BH vs. 4/225 (1.8%) of non-BH small intestine injury. AL was diagnosed 11.6 ± 5.6 days from index operation in small intestine BH and 9.7 ± 4.3 days in colonic BH. Adjusted RR for AL was 2.32 [0.77-6.95] for small intestinal and 4.83 [1.47-15.89] for colonic injuries. AL increased infections, ventilator days, ICU & total length of stay, reoperation, and readmission rates, although mortality was unchanged. CONCLUSION BH carries a significantly higher risk of AL, particularly in the colon, than other blunt intestinal injuries.

Diet-induced shifts in the gut microbiota influence anastomotic healing in a murine model of colonic surgery. Gut Microbes 2023; 15:2283147.

Abstract
Host diet and gut microbiota interact to contribute to perioperative complications, including anastomotic leak (AL). Using a murine surgical model of colonic anastomosis, we investigated how diet and fecal microbial transplantation (FMT) impacted the intestinal microbiota and if a predictive signature for AL could be determined. We hypothesized that a Western diet (WD) would impact gut microbial composition and that the resulting dysbiosis would correlate with increased rates of AL, while FMT from healthy, lean diet (LD) donors would reduce the risk of AL. Furthermore, we predicted that surgical outcomes would allow for the development of a microbial preclinical translational tool to identify AL. Here, we show that AL is associated with a dysbiotic microbial community characterized by increased levels of Bacteroides and Akkermansia. We identified several key taxa that were associated with leak formation, and developed an index based on the ratio of bacteria associated with the absence and presence of leak. We also highlight a modifiable connection between diet, microbiota, and anastomotic healing, potentially paving the way for perioperative modulation by microbiota-targeted therapeutics to reduce AL.

Abstract
Objectives The risk factors for anastomotic leak (AL) after resection and primary anastomosis for traumatic bucket handle injury (BHI) have not been previously defined. This multicenter study was conducted to address this knowledge gap. Methods This is a multicenter retrospective study on small intestine and colonic BHIs from blunt trauma between 2010 and 2021. Baseline patient characteristics, risk factors, presence of shock and transfusion, operative details, and clinical outcomes were compared using R. Results Data on 395 subjects were submitted by 12 trauma centers, of whom 33 (8.1%) patients developed AL. Baseline details were similar, except for a higher proportion of patients in the AL group who had medical comorbidities such as diabetes, hypertension, and obesity (60.6% vs. 37.3%, p=0.015). AL had higher rates of surgical site infections (13.4% vs. 5.3%, p=0.004) and organ space infections (65.2% vs. 11.7%, p<0.001), along with higher readmission and reoperation rates (48.4% vs. 9.1%, p<0.001, and 39.4% vs. 11.6%, p<0.001, respectively). There was no difference in intensive care unit length of stay or mortality (p>0.05). More patients with AL were discharged with an ostomy (69.7% vs. 7.3%, p<0.001), and the mean duration until ostomy reversal was 5.85±3 months (range 2-12.4 months). The risk of AL significantly increased when the initial operation was a damage control procedure, after adjusting for age, sex, injury severity, presence of one or more comorbidities, shock, transfusion of >6 units of packed red blood cells, and site of injury (adjusted RR=2.32 (1.13, 5.17)), none of which were independent risk factors in themselves. Conclusion Damage control surgery performed as the initial operation appears to double the risk of AL after intestinal BHI, even after controlling for other markers of injury severity. Level of evidence III.

Abstract
PURPOSE Anastomotic leakage (AL) after colorectal resection is a serious postoperative complication with grave consequences for patients. Despite several efforts to reduce its incidence, AL is still seen among 2-20% of colorectal cancer patients receiving an anastomosis. The use of tissue adhesives and sealants as an extra layer of protection around the anastomosis has shown promising results. We conducted a scoping review to provide an overview of the current knowledge on the effect of tissue adhesives and sealants on colorectal anastomosis healing, as well as their effect on the postoperative outcome. METHODS The databases of PubMed, Embase, and Cochrane Library were systematically searched on 14/10/2022. Studies addressing the use of a tissue adhesive or tissue sealant applied around a colorectal anastomosis, with the goal to prevent AL or to decrease AL-related complications, were included. We presented an overview of the available studies and summarized their results narratively. RESULTS Seven studies were included out of the 846 screened. All authors reported the rate of AL in their interventions group. Five of the studies found a decreased rate of AL compared to the control group. One study had no incidences of AL, while the last study had a seemingly low rate of AL but no comparison group. Information on secondary outcomes was sparingly reported, but the results hinted at a positive effect. CONCLUSION Tissue adhesives and sealants might have a beneficial effect on colorectal anastomosis healing. The literature is sparse, and this review has shown the need for further clinical studies.

Abstract
Colon leakage is one of the most severe complications in abdominal trauma or surgery cases. It can lead to severe abdominal infection and abdominal adhesions, resulting in prolonged hospital stays and increased mortality. In this study, a photosensitive hydrogel is proposed, which can swiftly form a strong adhesion coating on the damaged colon after UV irradiation, to realize quick cure and suture-free repair of colon leakage. The newly developed biological gel consists of hyaluronic acid methacryloyl (HAMA) and hyaluronic acid o-nitroso benzaldehyde (HANB) in the optimal ratio of 3: 1, which exerts both the rapid photocuring properties of HAMA and the strong tissue adhesion properties of HANB. HAMA/HANB shows excellent adhesion stability on wet surfaces, presenting controllable mechanical properties, ductility, adhesion stability, and chemical stability; it also evades foreign body response, which relieves the degree of abdominal adhesion. The underlying mechanism for HAMA/HANB promoting wound healing in colon leakage involves the reconstruction of the colon barrier, as well as the regulation of the immune reaction and neovascularization. In all, HAMA/HANB is a promising alternative suture-free approach for repairing colon leakage; it has a reliable healing effect and is expected to be extended to clinical application for other organ injuries.

Abstract
INTRODUCTION With the advent of multimodality therapy and minimally invasive surgical approaches, patients suffering from carcinoma esophagus are showing promising outcomes. Hence, the frontier needs to be widened to assess the postoperative quality of life (QoL) of those surviving carcinoma esophagus. The objective of the study was to determine the short-term outcomes of minimally invasive esophagectomy (MIE) /hybrid esophagectomies in carcinoma esophagus and the organ-specific QoL in survivors of MIE for carcinoma esophagus, and to compare health-related QoL in patients following MIE for carcinoma esophagus with the general population. METHODS AND MATERIALS A longitudinal study design was used to evaluate the short-term postoperative outcomes of patients undergoing MIE for carcinoma esophagus between July 1, 2021, to July 15, 2022, and analyze the QoL of those patients who survived at one year without tumor recurrence. QoL was assessed using the European Organization for the Research and Treatment of Cancer (EORTC) QoL Questionnaire (EORTC QLQ-C30) and the EORTC QoL Questionnaire - Oesophageal Cancer Module (EORTC QLQ-OES18). RESULTS A total of 15 patients who underwent minimal invasive/hybrid esophagectomy for esophageal carcinomawere included. Of these, 13 patients underwent hybrid esophagectomy while two patients underwent thoraco-laparoscopic esophagectomy. Squamous cell carcinoma was observed as the most common histological variant (60%) while 33% were adenocarcinoma and 6.7% lymphoma. The most common site of the tumor was the lower one-third esophagus (60%). Nine out of 15 patients developed postoperative complications needing prolonged ICU stay. One major anastomotic leak as well as one conduit necrosis was observed among 15 cases operated. Median length of hospital stay was 16 (IQR 12-24). QoL was assessed among 12 patients at the one-year follow-up excluding mortality cases and patients with tumor recurrence. The patients following MIE for carcinoma esophagus were observed to have low scores in physical functioning, role functioning, and social function when compared with the general population. Cognitive functioning and emotional function were not found to be significantly different. No statistically significant difference was observed in the global health status among the two groups. There was no significant difference found in the general symptoms score comparison of the MIE patients with the general population. When it comes to organ-specific symptom scales, reflux was observed as a major issue among the patients who survived carcinoma esophagus after undergoing MIE. Dysphagia and dry mouth received low scores suggestive of minor issues. Though analysis of global health QoL scores of those with postoperative complications and those who had uneventful recovery at one year revealed a higher score for the latter, it was not statistically significant. CONCLUSION Postoperative complications can prolong hospital stay, delay resuming normal work, and affect the global QoL of patients compared with those who recovered uneventfully. Physical and role functions were observed to be deficient among survived patients when compared with the normal population. Nutritional prehabilitation, cutting-edge surgical practice including minimally invasive techniques, minimizing deviation from normal postoperative recovery by high-quality ICU care, and postoperative rehabilitation are the cornerstones to ensure better QoL.

Risk factors for gastrointestinal perforation and anastomotic leak in patients submitted to cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107020. [PMID: 37597284 DOI: 10.1016/j.ejso.2023.107020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 07/22/2023] [Accepted: 08/11/2023] [Indexed: 08/21/2023]
Abstract
BACKGROUND Gastrointestinal leak is one of the most feared complications after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) and harbors significant postoperative morbidity and mortality. We aim to identify risk-factors for anastomotic leak (AL) and gastrointestinal perforation (GP) to optimize postoperative outcomes of this population. METHODS We performed a retrospective analysis of 1043 consecutive patients submitted to CRS in a single institution. Potential risk factors for AL and GP, both related to patient overall condition, disease status and surgical technique were reviewed. RESULTS Anastomotic leaks were identified in 5.2% of patients, and GPs in 7.0%. The independent risk-factors for AL were age at surgery (OR1.40; CI95% 1.10-1.79); peritoneal cancer index (PCI) (OR1.04, CI95% 1.01-1.07); Cisplatin dose >240 mg during HIPEC (OR3.53; CI95% 1.47-8.56) and the presence of colorectal (CR) or colo-colic (CC) anastomosis (OR5.09; CI95% 2.71-9.53, and 4.58; CI95% 1.22-17.24 respectively). Male gender and intraoperative red blood cell transfusions were the only independent risk factors for GP identified (OR1.70; CI95% 1.04-2.78 and 1.06; CI95% 1.01-1.12, respectively). Regarding 30-day and 90-day postoperative mortality, independent risk-factors were mainly related to patient's overall condition. CONCLUSION Gastrointestinal leaks are a frequent source of postoperative morbidity, mainly at the expense of GP. A careful and systematic intraoperative revision of all potential gastrointestinal injuries is equally critical to perfecting anastomotic fashioning techniques to decrease gastrointestinal complication rates. We identified multiple risk-factors for AL and GP related to disease status and patient condition. Our study suggests that patient-related conditions are of paramount relevance, highlighting the importance of patient selection and preoperative patient optimization.

Outcomes of Endoscopic Intervention Using Over-the-Scope Clips for Anastomotic Leakage Involving Secondary Fistula after Gastrointestinal Surgery: A Japanese Multicenter Case Series. Diagnostics (Basel) 2023; 13:2997. [PMID: 37761364 PMCID: PMC10528500 DOI: 10.3390/diagnostics13182997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/13/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
BACKGROUND The over-the-scope clip (OTSC) is a highly effective clipping device for refractory gastrointestinal disease. However, Japanese data from multicenter studies for anastomotic leakage (AL) involving a secondary fistula after gastrointestinal surgery are lacking. Therefore, this study evaluated the efficacy and safety of OTSC placement in Japanese patients with such conditions. METHODS We retrospectively collected data from 28 consecutive patients from five institutions who underwent OTSC-mediated closure for AL between July 2017 and July 2020. RESULTS The AL and fistula were located in the esophagus (3.6%, n = 1), stomach (10.7%, n = 3), small intestine (7.1%, n = 2), colon (25.0%, n = 7), and rectum (53.6%, n = 15). The technical success, clinical success, and complication rates were 92.9% (26/28), 71.4% (20/28), and 0% (0/28), respectively. An age of <65 years (85.7%), small intestinal AL (100%) and colonic AL (100%), defect size of <10 mm (82.4%), time to OTSC placement > 7 days (84.2%), and the use of simple suction (78.9%) and anchor forceps (80.0%) were associated with higher clinical success rates. CONCLUSION OTSC placement is a useful therapeutic option for AL after gastrointestinal surgery.

Abstract
AbstractObjectiveThe most important factor in abdominal surgery is the successful healing of the intestinal anastomosis performed. This study aims to evaluate the role of C‐reactive protein (CRP) in predicting anastomotic dehiscence in the first week following surgery.MethodsThe study included 100 patients surgically treated over a period of 1 year. Postoperative (p/o) values of CRP, leukocyte (white blood cells [WBCs]) and body temperature (BT) were measured in relation to the development of p/o complications.ResultsCRP p/o values were significantly higher in patients with complications and proved helpful in predicting p/o complications, while WBC and BT were not. For the development of anastomotic leakage, receiver operating characteristic curve shows the earliest diagnostic accuracy on the third p/o day with the cut‐off value of 115.1 mg/L; however, the largest area under the curve was on the fifth p/o day with a cut‐off value of 59.2 mg/L, a sensitivity of 89%, a specificity of 61%, a positive predictive value (PPV) of 21.9 and a negative predictive value (NPV) of 100.ConclusionsMeasurement of p/o CRP values may indicate problematic healing of digestive tract anastomosis before the appearance of clinical signs. High sensitivity and high NPV allow us to rule out p/o complications and anastomotic dehiscence with great certainty and safely discharge these patients from the hospital.

Intraoperative bowel perfusion assessment methods and their effects on anastomotic leak rates: meta-analysis. Br J Surg 2023; 110:1131-1142. [PMID: 37253021 PMCID: PMC10416696 DOI: 10.1093/bjs/znad154] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 03/24/2023] [Accepted: 04/29/2023] [Indexed: 06/01/2023]
Abstract
BACKGROUND Anastomotic leak is one of the most feared complications of colorectal surgery, and probably linked to poor blood supply to the anastomotic site. Several technologies have been described for intraoperative assessment of bowel perfusion. This systematic review and meta-analysis aimed to evaluate the most frequently used bowel perfusion assessment modalities in elective colorectal procedures, and to assess their associated risk of anastomotic leak. Technologies included indocyanine green fluorescence angiography, diffuse reflectance spectroscopy, laser speckle contrast imaging, and hyperspectral imaging. METHODS The review was preregistered with PROSPERO (CRD42021297299). A comprehensive literature search was performed using Embase, MEDLINE, Cochrane Library, Scopus, and Web of Science. The final search was undertaken on 29 July 2022. Data were extracted by two reviewers and the MINORS criteria were applied to assess the risk of bias. RESULTS Some 66 eligible studies involving 11 560 participants were included. Indocyanine green fluorescence angiography was most used with 10 789 participants, followed by diffuse reflectance spectroscopy with 321, hyperspectral imaging with 265, and laser speckle contrast imaging with 185. In the meta-analysis, the total pooled effect of an intervention on anastomotic leak was 0.05 (95 per cent c.i. 0.04 to 0.07) in comparison with 0.10 (0.08 to 0.12) without. Use of indocyanine green fluorescence angiography, hyperspectral imaging, or laser speckle contrast imaging was associated with a significant reduction in anastomotic leak. CONCLUSION Bowel perfusion assessment reduced the incidence of anastomotic leak, with intraoperative indocyanine green fluorescence angiography, hyperspectral imaging, and laser speckle contrast imaging all demonstrating comparable results.

Abstract
Background Anastomotic leakage is a major complication in colorectal surgery, resulting in significant morbidity and mortality rates. Despite substantial progress in surgical technique, anastomotic leakage rates remain stable. An early diagnosis of anastomotic leaks was proven to reduce adverse outcomes and improve survival. Objective This study aims to find a novel scoring system for detecting anastomotic leaks using inflammatory and nutritional indicators after colorectal surgery. Our purpose was to analyze the diagnostic accuracy of leak scores ( ( CRP POD 3 ) ( CRP POD 1 ) ∗ preoperative albumin level ) in predicting postoperative complications. Design The study included colorectal cancer patients who underwent curative surgery at Koc University Hospital between 2014 and 2018. Patients were categorized into two groups depending on the presence of anastomotic leaks and compared in terms of preoperative albumin levels, CRP levels in postoperative days 1 and 3, anastomotic leakage rates, length of hospital stay, and CRP quotient, which was calculated by dividing POD 3 CRP level to POD 1 CRP level. The bedside leak score is calculated by dividing the CRP quotient by the preoperative albumin level. The predictive value of bedside leak score, CRP quotient, and preoperative albumin levels in estimating anastomotic leakage was analyzed, and a cutoff value for the leak score was calculated. Results A total of 184 patients were included in the study. The leak score, CRP POD 3-1 ratio, and preoperative albumin levels were found to successfully detect anastomotic leakage. The area under the curve for the leak score was calculated as 0.78. The optimal cutoff value was found to be 50.3 for the bedside leak score, which shows 90.9% sensitivity and 59.3% specificity. Conclusion The leak score may represent a valuable diagnostic tool for detecting patients at risk for anastomotic leakage after colorectal surgery and planning a better strategy to reduce morbidity and mortality rates and associated costs. However, further multicenter studies with large cohorts are necessary to confirm these results.

Abstract
BACKGROUND Anastomotic leakage (AL) as a result of creation of a colorectal/anal anastomosis still represents a frequent complication of colorectal surgery, with short- and long-term consequences on postoperative morbidity, quality of life and oncological outcomes. However, early diagnosis of AL may result in improved outcomes. The aims of this study were to evaluate the diagnostic accuracy of water-soluble contrast enema (WSCE), contrast enema computed tomography (CECT) and endoscopy in identifying AL and to identify the diagnostic procedure that is most accurate. METHODS A systematic review and meta-analysis of 19 studies accounting for a total of 25 tests reporting diagnostic accuracy estimates was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy Studies (PRISMA-DTA) guidelines up to June 2021. For the diagnostic tests we evaluated the pooled estimates and conducted pairwise comparisons. RESULTS For WSCE, the pooled sensitivity was 0.50, the pooled specificity was 0.99 and the area under the curve (AUC) was 0.91. For endoscopy, the pooled sensitivity was 0.69, specificity was 1.00 and AUC was 0.99. The pooled sensitivity and specificity for CECT were 0.89 and 1.00, respectively; the AUC was 0.99. The comparison between CECT and WSCE highlighted a significantly greater sensitivity (p = 0.04) for CECT, whereas no difference was found for specificity. Compared with CECT, endoscopy was not significantly more accurate in terms of either sensitivity or specificity. Endoscopy was found to be significantly more specific than WSCE (p = 0.031) but no difference was found for sensitivity. CONCLUSION Water-soluble contrast enema, endoscopy and CECT have an elevated diagnostic accuracy. However, WSCE is less accurate than either endoscopy or CECT. Although greater sensitivity was demonstrated for CECT compared with endoscopy, this was not significant.

Abstract
Anastomotic leakage is one of the common causes of serious morbidity and death after gastrectomy. The use of surgical treatment for leakage decreased due to the development of nonsurgical management. However, if nonsurgical management fails to control the spread of intra-abdominal infection, emergency surgical treatment is required. The authors wished to determine in which cases surgical treatment is needed for postoperative leakage and to identify treatment and prevention strategies. If a patient's vital signs are stable, local abscesses can be cured by conservative treatment after percutaneous drain insertion; if there is no improvement in anastomotic leakage, endoscopic treatment such as clipping, vacuum, and stent placement can be performed. If a patient's vital signs are unstable or patient shows diffuse peritonitis, surgical treatment should be performed. A surgical plan can be established according to leakage location. The duodenal stump may first require conservative treatment. It is recommended that surgical treatment be attempted first for anastomotic leakage of gastrojejunostomy site and gastric stump in remnant stomach. In conclusion, the need for surgical treatment is determined depending on vital signs and presence of diffuse peritonitis. During surgical treatment, a strategic approach is required according to the patient's condition and the anatomical location of leakage.

Abstract
Background Laser Tissue Soldering (LTS) is a promising tissue bonding technique in which a solder is applied between the tissues and then irradiated by laser, causing it to solidify and form links with the tissue. Methods A comprehensive systematic review summarizing the state of research of LTS in the gastrointestinal tract. Results Most studies were conducted on large animal tissues, using liquid proteinaceous solder, and irradiated by a continuous wave laser at 808 nm. LTS can provide better sealing and burst pressure than conventional methods. The application of LTS on top of or in addition to sutures showed an impressive increase in burst pressures. LTS may decrease the inflammatory and foreign body reaction caused by sutures. Conclusions LTS has strong potential to be applied in a clinical setting in leak prevention and in closure of gastrointestinal structures as an adjunct or additional anastomotic technology, decreasing leak rates, morbidity, and mortality.

Risk prediction of esophageal squamous cell carcinoma recurrence in patients who underwent esophagectomy after receiving neoadjuvant treatment: a nationwide retrospective study in Japan. Esophagus 2023:10.1007/s10388-023-01002-2. [PMID: 37029845 DOI: 10.1007/s10388-023-01002-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 03/31/2023] [Indexed: 04/09/2023]
Abstract
BACKGROUND Although neoadjuvant treatment (NAT) has become the standard of care for patients with locally advanced esophageal cancer, the risk of recurrence remains high. The risk must be predicted accurately, so that appropriate adjuvant therapy can be planned. We aimed to develop a model predicting recurrence of esophageal squamous cell carcinoma (ESCC) in patients who received NAT before esophagectomy. METHODS This nationwide study included 3874 patients from 85 institutions. Patients who underwent NAT and then surgery for ESCC were eligible. We developed a Cox proportional hazards model and created a nomogram to predict disease recurrence after NAT and curative esophagectomy. RESULTS Of the patients, 268 (6.9%), 1280 (33.0%), 2006 (51.8%), and 320 (8.3%) had clinical stage I, II, III, and IV tumors, respectively. The 5-year recurrence rate was 45.1% (95% confidence interval 43.4%-46.7%). Multivariable analysis revealed that body mass index, type of neoadjuvant treatment, primary tumor location, operative blood loss, pathological tumor stage, pathological therapeutic effect, and leakage were independently associated with disease recurrence. Using 13 commonly measured perioperative variables, we created a predictive nomogram, and the area under the curve was 0.783 (95% confidence interval 0.766-0.800). This nomogram was also adequately validated internally and had excellent calibration capacity (calibration slope, 0.992). CONCLUSIONS The model developed in this study adequately predicted ESCC recurrence in patients who underwent NAT and then esophagectomy. Further research with this nomogram is needed to assess the effect of adjuvant therapy in patients at high risk for recurrence.

Risk factors and conservative therapy outcomes of anastomotic leakage after gastrectomy: Experience of 3,926 patients from a single gastric surgical unit. Front Oncol 2023; 13:1163463. [PMID: 37007118 PMCID: PMC10050334 DOI: 10.3389/fonc.2023.1163463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 02/28/2023] [Indexed: 03/17/2023] Open
Abstract
BackgroundAnastomotic leakage (AL) after gastrectomy is one of the severest postoperative complications and is related to increasing mortality. In addition, no consensus guidelines about strategies of AL treatment have been established. This large cohort study aimed to inspect the risk factors and efficacy of the conservative treatment for AL in patients with gastric cancer.MethodsWe reviewed the clinicopathological data of 3,926 gastric cancer patients undergoing gastrectomy between 2014 and 2021. Results contained the rate, risk factors, and conservative therapy outcomes of AL.ResultsIn total, 80 patients (2.03%, 80/3,926) were diagnosed with AL, and esophagojejunostomy was the most frequent AL site (73.8%, 59/80). Among them, one patient (2.5%, 1/80) died. Multivariate analysis indicated that low albumin concentration (P = 0.001), presence of diabetes (P = 0.025), laparoscopic method (P < 0.001), total gastrectomy (P = 0.003), and proximal gastrectomy (P = 0.002) were predicting factors for AL. The closure rate for the conservative treatment of AL in the first month after AL diagnosis was 83.54% (66/79), and the median time from leakage diagnosis to the closure of leakage was 17 days (interquartile range 11–26 days). Low level of plasma albumin (P = 0.004) was associated with late leakage closures. In terms of 5-year overall survival, no significant difference was observed between patients with and without AL.ConclusionThe incidence of AL after gastrectomy is associated with low albumin concentration, diabetes, the laparoscopic method, and extent of resection. The conservative treatment is relatively safe and effective for the AL management in patients after gastric cancer surgery.

Abstract
PURPOSE Real-time intraoperative perfusion assessment may reduce anastomotic leaks. Laser speckle contrast imaging (LSCI) provides dye-free visualization of perfusion by capturing coherent laser light scatter from red blood cells and displays perfusion as a colormap. Herein, we report a novel method to precisely quantify intestinal perfusion using LSCI. METHODS ActivSight™ is an FDA-cleared multi-modal visualization system that can detect and display perfusion via both indocyanine green imaging (ICG) and LSCI in minimally invasive surgery. An experimental prototype LSCI perfusion quantification algorithm was evaluated in porcine models. Porcine small bowel was selectively devascularized to create regions of perfused/watershed/ischemic bowel, and progressive aortic inflow/portal vein outflow clamping was performed to study arterial vs. venous ischemia. Continuous arterial pressure was monitored via femoral line. RESULTS LSCI perfusion colormaps and quantification distinguished between perfused, watershed, and ischemic bowel in all vascular control settings: no vascular occlusion (p < 0.001), aortic occlusion (p < 0.001), and portal venous occlusion (p < 0.001). LSCI quantification demonstrated similar levels of ischemia induced both by states of arterial inflow and venous outflow occlusion. LSCI-quantified perfusion values correlated positively with higher mean arterial pressure and with increasing distance from ischemic bowel. CONCLUSION LSCI relative perfusion quantification may provide more objective real-time assessment of intestinal perfusion compared to conventional naked eye assessment by quantifying currently subjective gradients of bowel ischemia and identifying both arterial/venous etiologies of ischemia.

Walsh TN. The Esophagogastric Anastomosis: The Importance of Anchoring Sutures in Reducing Anastomotic Leak Rates. ANNALS OF SURGERY OPEN 2023; 4:e231. [PMID: 37600864 PMCID: PMC10431275 DOI: 10.1097/as9.0000000000000231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 11/29/2022] [Indexed: 02/04/2023] Open
Abstract
Background The incidence of anastomotic leakage in gastrointestinal surgery is highest after esophagogastric anastomosis, with leakage rates of 10% to 38% still being reported, but little consensus as to cause or corrective. The role of anastomotic tension from a series of physiological forces acting on the anastomosis from the moment of recovery from anesthesia may be underestimated. It was hypothesized that anchoring the conduit in the mediastinum would provide the greatest protection during the vulnerable healing phase. Patients and Methods A prospectively maintained database was interrogated for anastomotic leakage following the introduction of an anastomotic technique employing anchoring sutures where the gastric conduit was secured to the mediastinal pleura with 3 obliquely inserted load-bearing sutures. A contrast study was performed between days 5 and 7 and all intrahospital mortalities underwent autopsy. Clinical, radiological, and autopsy leaks were recorded. Results Of 146 intrathoracic esophagogastric anastomoses in 144 patients, 81 (55%) of which were stapled, there was 1 clinical leak and 1 patient with an aortoenteric fistula, considered at autopsy to be possibly due to an anastomotic leak, to give an anastomotic leak rate of 2 in 146 (1.37%). Conclusion The low anastomotic leak rate in this series is potentially due to the protective effect of anchoring sutures, the chief difference from an otherwise standard anastomotic technique. These sutures protect the anastomosis from a series of distracting forces during the most vulnerable phase of healing. It is intuitive that the absence of tension would also reduce any risk posed by a minor impairment of blood supply or any imperfection of the technique.

Abdominal emergency surgery in patients with hematological malignancies: a retrospective single-center analysis. World J Emerg Surg 2023; 18:12.

Abstract
BACKGROUND Hematologic patients requiring abdominal emergency surgery are considered to be a high-risk population based on disease- and treatment-related immunosuppression. However, the optimal surgical therapy and perioperative management of patients with abdominal emergency surgery in patients with coexisting hematological malignancies remain unclear. METHODS We here report a single-center retrospective analysis aimed to investigate the impact of abdominal emergency surgery due to clinically suspected gastrointestinal perforation (group A), intestinal obstruction (group B), or acute cholecystitis (group C) on mortality and morbidity of patients with coexisting hematological malignancies. All patients included in this retrospective single-center study were identified by screening for the ICD 10 diagnostic codes for gastrointestinal perforation, intestinal obstruction, and ischemia and acute cholecystitis. In addition, a keyword search was performed in the database of all pathology reports in the given time frame. RESULTS A total of 56 patients were included in this study. Gastrointestinal perforation and intestinal obstruction occurred in 26 and 13 patients, respectively. Of those, 21 patients received a primary gastrointestinal anastomosis, and anastomotic leakage (AL) occurred in 33.3% and resulted in an AL-related 30-day mortality rate of 80%. The only factor associated with higher rates of AL was sepsis before surgery. In patients with suspected acute cholecystitis, postoperative bleeding events requiring abdominal packing occurred in three patients and lead to overall perioperative morbidity of 17.6% and surgery-related 30-day mortality of 5.9%. CONCLUSION In patients with known or suspected hematologic malignancies who require emergency abdominal surgery due to gastrointestinal perforation or intestinal obstruction, a temporary or permanent stoma might be preferred to a primary intestinal anastomosis.

Abstract
Introducción. La fuga anastomótica es la complicación más grave del tratamiento quirúrgico del cáncer de colon por su alta morbimortalidad. El diagnóstico evidente, manifestado por la salida de contenido intestinal por drenajes o la herida quirúrgica, ocurre tardíamente (entre el 6º y 8º día). El objetivo de este trabajo fue estudiar la variación de los valores de la proteína C reactiva postoperatoria para hacer un diagnóstico precoz.
Métodos. Estudio observacional, analítico, retrospectivo, de una cohorte de pacientes con neoplasia, en quienes se realizó cirugía oncológica con anastomosis intestinal, entre enero de 2019 y diciembre de 2021. Se midieron los valores en sangre de proteína C reactiva postoperatoria (1°, 3° y 5° días).
Resultados. Se compararon 225 casos operados que no presentaron fuga con 45 casos con fuga. En los casos sin fuga, el valor de proteína C reactiva al 3º día fue de 148 mg/l y al 5º día de 71 mg/l, mientras en los casos con fuga, los valores fueron de 228,24 mg/l y 228,04 mg/l, respectivamente (p<0,05). Para un valor de 197 mg/l al 3º día la sensibilidad fue de 77 % y para un valor de 120 mg/l al 5º día la sensibilidad fue de 84 %.
Conclusión. El mejor resultado de proteína C reactiva postoperatoria para detectar precozmente la fuga anastomótica se observó al 5º día. El valor de 127 mg/l tuvo la mejor sensibilidad, especificidad y valor predictivo negativo, lo cual permitiría el diagnóstico temprano y manejo oportuno de esta complicación.

Abstract
Anastomotic leakage is a feared complication of many different types of gastrointestinal surgery. It is important to identify patients with leaks early because sepsis may develop quickly. Suspected leaks are typically confirmed by either fluoroscopy or computed tomography with oral contrast. This article presents a novel method to confirm the presence of a gastrointestinal anastomotic leak when standard imaging and clinical presentation are ambiguous.

Abstract
BACKGROUND Decision-making under uncertainty may be influenced by an individual's personality. The primary aim was to explore associations between surgeon personality traits and colorectal anastomotic decision-making. METHODS Colorectal surgeons worldwide participated in a two-part online survey. Part 1 evaluated surgeon characteristics using the Big Five Inventory to measure personality (five domains: agreeableness; conscientiousness; extraversion; emotional stability; openness) in response to scenarios presented in Part 2 involving anastomotic decisions (i.e. rejoining the bowel with/without temporary stomas, or permanent diversion with end colostomy). Anastomotic decisions were compared using repeated-measure ANOVA. Mean scores of traits domains were compared with normative data using two-tailed t tests. RESULTS In total, 186 surgeons participated, with 127 surgeons completing both parts of the survey (68.3 per cent). One hundred and thirty-one surgeons were male (70.4 per cent) and 144 were based in Europe (77.4 per cent). Forty-one per cent (77 surgeons) had begun independent practice within the last 5 years. Surgeon personality differed from the general population, with statistically significantly higher levels of emotional stability (3.25 versus 2.97 respectively), lower levels of agreeableness (3.03 versus 3.74), extraversion (2.81 versus 3.38) and openness (3.19 versus 3.67), and similar levels of conscientiousness (3.42 versus 3.40 (all P <0.001)). Female surgeons had significantly lower levels of openness (P <0.001) than males (3.06 versus 3.25). Personality was associated with anastomotic decision-making in specific scenarios. CONCLUSION Colorectal surgeons have different personality traits from the general population. Certain traits seem to be associated with anastomotic decision-making but only in specific scenarios. Further exploration of the association of personality, risk-taking, and decision-making in surgery is necessary.

The Effects of Anastomotic Leaks on the Net Revenue from Colon Surgery. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19159426.

Abstract
Background: Complications in colon surgery can have severe health consequences, while at the same time, they are associated with increased costs. An anastomotic leak (AL) is associated with significantly increased costs compared to cases without. The aim of our analysis was to evaluate, which individual processes and patient-unrelated factors influencing the treatment process of colon surgery are responsible for the financial burden in patients with AL. Methods: Data from 263 patients who underwent colon surgery in Wetzikon hospital between January 2018 and December 2020 and was analyzed. In these 263 cases, 12 anastomotic leaks occurred and were compared with 36 cases without AL using a Propensity Score Matching (PSM). The covariates for the PSM have been Age, Sex, and Type of Surgery (t value: −3.26, p-value: 0.001). Results: A total of 48 surgeries were broken down in terms of costs and profitability. This reflected a mean deficit of −37,527 CHF per case (range from −130.05 to +755 CHF) for patients with AL, whereas a mean profit of 1590 CHF per case (range from −24.37 to +12.65 CHF) for those without AL (p < 0.001). Thus, the difference in profit showed a factor of 24.6 with an overall significant negative outcome for the occurrence of AL. The main cost contributing factors were the length of hospital stay (~p < 0.05) and length of intensive care (p < 0.05), whereas neither surgical operation time and anesthesia time nor surgical access, insurance status, indication or type of operation had a significant influence on the net revenue. Conclusion: AL after colon surgery leads to a significant deficit regarding the net revenue. Regarding process optimization, our analysis identified several sectors of non-patient-related, yet cost-influencing variables that should be addressed in future evaluations and optimization of the colon surgery treatment processes.

Abstract
Background The aim of this prospective study was to determine the effect of mesenteric vascular evaluation using pre-operative multidetector computed tomography angiography (MDCTA) and intraoperative indocyanine green (ICG) angiography on reducing the anastomotic leak rate of colorectal cancer patients undergoing minimally invasive resection. Methods Twenty-seven consecutive patients with colorectal cancer were studied, 18 males and 9 females, average age 69.1 ± 3.9 years. All patients underwent pre-operative mesenteric vascular evaluation using MDCTA with three-dimensional (3D) reconstruction and intraoperative evaluation of perfusion using ICG angiography. Twelve patients underwent laparoscopic resection (Olympus Visera Elite II OTV-S200) and 15 patients underwent robotic resection (DaVinci Si). Colorectal resection lines and anastomoses were guided by intraoperative ICG perfusion. Postoperative anastomotic leaks were assessed. Results Pre-operative MDCTA 3D reconstructions defined the left colic and sigmoid artery anatomy and guided operative planning. The intraoperative ICG angiography resulted in a change of the planned lines of resection in seven patients (26%). The rate of postoperative anastomotic leaks in this study was 0% (0/27), compared to a leak rate of 6.8% at our institution in the preceding two years. Conclusion Pre-operative evaluation of mesenteric vascular anatomy using MDCTA with 3D reconstruction and intraoperative evaluation of perfusion using ICG angiography were found to be technically feasible and safe. An appropriately designed study should be undertaken to prove whether it was truly effective at reducing the postoperative anastomotic leak rate in colorectal cancer patients undergoing minimally invasive resection at our institution.

Abstract
Background Nationwide research about the clinical and economic burden caused by anastomotic leakage (AL) has not been published yet in Korea. This study assessed the AL rate and quantified the economic burden using the nationwide database. Methods This real world evidence study used health claims data provided by the Korean Health Insurance Review and Assessment Service (HIRA, which showed that 156,545 patients underwent anterior resection (AR), low anterior resection (LAR), or ultra-low anterior resection (uLAR) for colorectal cancer (CRC) between January 1, 2007 and January 31, 2020. The incidence of AL was identified using a composite operational definition, a composite of imaging study, antibacterial drug use, reoperation, or image-guided percutaneous drainage. Total hospital costs and length of stay (LOS) were evaluated in patients with AL versus those without AL during index hospitalization and within 30 days after the surgery. Results Among 120,245 patients who met the eligibility criteria, 7,194 (5.98%) patients had AL within 30 days after surgery. Male gender, comorbidities (diabetes, metastatic disease, ischemic heart disease, ischemic stroke), protective ostomy, and multiple linear stapler use, blood transfusion, and urinary tract injury were associated with the higher odds of AL. Older age, rectosigmoid junction cancer, AR, LAR, and laparoscopic approach were related with the reduced odds of AL. Patients with AL incurred higher costs for index hospitalization compared to those without AL (8,991 vs. 7,153 USD; p<0.0001). Patients with AL also required longer LOS (16.78 vs. 14.22 days; p<0.0001) and readmissions (20.83 vs. 13.93 days; p<0.0001). Conclusion Among patients requiring resection for CRC, the occurrence of AL was associated with significantly increased costs and LOS. Preventing AL could not only produce superior clinical outcomes, but also reduce the economic burden for patients and payers.

Abstract
INTRODUCTION Accurate early diagnosis of a gastrointestinal anastomotic leak remains a challenge. When an anastomotic leak develops, the electrical properties of the tissue undergoing inflammatory processes change, resulting from the extravasation of inflammatory fluid and cellular infiltration. The method described here intends to provide a novel early anastomotic leak warning system based upon measurable changes in tissue impedance nearby an acute inflammatory process. METHODS A biodegradable Mg-alloy was compared with a nonabsorbable stainless steel (STS) electrode connected to a wireless recording system for impedance measurement. In vitro measurements were made in physiological solutions and small animal (eight mice) and large animal (eight pigs) models with an anastomotic leak simulated by an open colotomy. Measurements were made at 10 mm intervals from the open colon at baseline and up to 120 min comparing these with a sutured colonic wound and normal tissue. RESULTS In-vitro biodegradable magnesium electrode impedance evaluation showed good sensitivity to different media due to its environmental corrosion properties. The impedance of an acidic environment (1.06 ± 0.02 kΩ for citric acid) was twice that of phosphate-buffered saline (PBS) (0.64 ± 0.008 kΩ) with a distinction between Normal Saline (0.42 ± 0.013 kΩ) and PBS (0.64 ± 0.008 kΩ). This was in contrast to the performance characteristics of the control STS electrodes, where impedance in an acidic environment was lower than saline or PBS (citric acid:0.76 ± 0.01 kΩ versus PBS: 1.32 ± 0.014 kΩ). In a mouse model simulating an anastomotic leak, there was a significant increase in impedance after 120 min when compared with controls (99.7% increase versus 9.6% increase, respectively; P < 0.02). This effect was confirmed in a pig model when relative impedance measurements of the leak and control groups were compared (1.86 ± 0.46 versus 1.07 ± 0.02, respectively; P < 0.027). CONCLUSIONS Electrophysiological measurement shows diagnostic sensitivity for a gastrointestinal leak with potential clinical utility in the postoperative detection of early intra-abdominal sepsis. Further investigation of biodegradable tissue sensors capable of monitoring an early anastomotic leak is required.

Abstract
BACKGROUND Wound class in hernia repairs impacts surgical technique and outcomes. Hernia recurrence and complications are high when dirty wounds are treated in one stage. We hypothesize patients who undergo intentionally staged repairs are less likely to have adverse outcomes and associated costs. METHODS Patients were identified by retrospective chart review. Patient characteristics and outcome variables were collected. An economic analysis of cost variables was performed using medical records and published meta-analyses. RESULTS There were 8 patients in the staged repairs group and 10 patients in the control group. Length of stay was 14.9 days (±8.8), and 8.7 days (±6.4), respectively. Rate of hernia recurrence within 1 year was 14.3% and 37.5%. Rate of mesh infection at 30 days was 0% and 10%. Compared to controls, delayed-immediate repairs had a nearly 2-fold index surgical cost. DISCUSSION Although there is an increased cost associated with delayed-immediate repairs, this cost may be offset by the decreased infection, seroma, dehiscence, enterocutaneous fistula formation, and hernia recurrence rate that necessitates future interventions. Further data collection is required to determine if clinical and economic benefit is seen long-term.

Abstract
BACKGROUND Gastrointestinal anastomotic leakage is a dreaded complication despite advancements in surgical technique. Photochemical tissue bonding (PTB) is a method of sealing tissue surfaces utilizing photoactive dye. We evaluated if crosslinked human amniotic membrane (xHAM) photosealed over the enteroenterostomy would augment anastomotic strength in a trauma-relevant swine hemorrhagic shock model. METHODS Yorkshire swine (40-45 kg, n = 14) underwent midline laparotomy and sharp transection of the small intestine 120 cm proximal to the ileocecal fold. Immediately following intestinal transection, a controlled arterial bleed was performed to reach hemorrhagic shock. Intestinal repair was performed after 60 minutes and autotransfusion of the withdrawn blood was performed for resuscitation. Animals were randomized to small intestinal anastomosis by one of the following methods (seven per group): suture repair (SR), or SR with PTB augmentation. Animals were euthanized at postoperative Day 28 and burst pressure (BP) strength testing was performed on all excised specimens. RESULTS Mean BP for SR, PTB, and native tissue groups were 229 ± 40, 282 ± 21, and 282 ± 47 mmHg, respectively, with the SR group statistically significantly different on analysis of variance (p = 0.02). Post-hoc Tukey all-pairs comparison demonstrated a statistically significant difference in burst pressure strength between the SR only and the PTB group (p = 0.04). All specimens in SR group ruptured at the anastomosis upon burst pressure testing, while all specimens in the PTB group ruptured at least 2.5 cm from the anastomosis. CONCLUSION Photosealing with xHAM significantly augments the strength of small intestinal anastomosis performed in a trauma porcine model.

Surg Endosc 2022; 36:5812-5821.

Abstract
BACKGROUND Anastomotic leakage (AL) after Ivor Lewis esophagectomy with intrathoracic anastomosis carries a significant morbidity. Adequate perfusion of the gastric tube (GT) is an important predictor of anastomotic integrity. Recently, near infrared fluorescent (NIRF) imaging using indocyanine green (ICG) was introduced in clinical practice to evaluate tissue perfusion. We evaluated the feasibility and efficacy of GT indocyanine green angiography (ICGA) after Ivor Lewis esophagectomy. METHODS This retrospective analysis used data from a prospectively kept database of consecutive patients who underwent Ivor Lewis (IL) esophagectomy with GT construction for cancer between January 2016 and December 2020. Relevant outcomes were feasibility, ICGA complications and the impact of ICGA on AL. RESULTS 266 consecutive IL patients were identified who matched the inclusion criteria. The 115 patients operated with perioperative ICGA were compared to a control group in whom surgery was performed according to the standard of care. ICGA perfusion assessment was feasible and safe in all 115 procedures and suggested a poorly perfused tip in 56/115 (48.7%) cases, for which additional resection was performed. The overall AL rate was 16% (43/266), with 12% (33/266) needing an endoscopic our surgical intervention and 6% (17/266) needing ICU support. In univariable and multivariable analyses, ICGA was not correlated with the risk of AL (ICGA:14.8% vs non-ICGA:17.2%, p = 0.62). However, poor ICGA perfusion of the GT predicted a higher AL rate, despite additional resection of the tip (ICGA poorly perfused: 19.6% vs ICG well perfused: 10.2%, p = 0.19). CONCLUSIONS ICGA is safe and feasible, but did not result in a reduction of AL. The interpretation and necessary action in case of perioperative presence of ischemia on ICGA have yet to be determined. Prospective randomized trials are warranted to analyze its benefit on AL in esophageal surgery. Trial registration Ethical approval for a prospective esophageal surgery database was granted by the Ethical committee of the Ghent University Hospital. Belgian registration number: B670201111232. Ethical approval for this retrospective data analysis was granted by our institutional EC. Registration number: BC-09216.

Abstract
While perforations, postoperative fistulas, and leaks have traditionally led to surgical or interventional radiology consultation for management, the introduction of the over-the-scope clip has allowed increased therapeutic possibilities for endoscopists. While primarily limited to case reports and series, the over-the-scope clip successfully manages gastrointestinal bleeding, perforations, as well as postoperative leaks and fistulas. Retrospective studies have demonstrated a relatively high success rate and a low complication rate. Given the similarity to variceal banding equipment, the learning curve with the over-the-scope clip is rapid. However, given the higher risk of procedures involving the use of the over-the-scope clip, it is essential to obtain the scope in a stable position and grasp sufficient tissue with the cap using a grasping tool and/or suction. From our experience, while closure may be successful in lesions sized up to 3 cm, successful outcomes are obtained for lesions sized <1 cm. Ultimately, given the limited available data, prospective randomized trials are needed to better evaluate the utility of the over-the-scope clip in various clinical scenarios, including fistula and perforation management.

Abstract
Surgeons universally dread gastrointestinal anastomotic leaks, yet the precise definition is not widely agreed on despite international consensus guidelines. Likewise, leaks are not uniformly reported which makes comparisons across studies flawed. Leak rates range from 1 to 3% for ileocolonic, 0.5 to 18% for colorectal, and 5 to 19% for coloanal anastomoses. The sequelae of an anastomotic leak vary but generally correlate with the need for a change in clinical management, from minimal changes to the need for reoperation. Short- and long-term outcomes can be life-altering or life-threatening. Temporary or permanent stomas may be necessary and low pelvic anastomotic leaks may affect bowel function. For cancer patients, leaks can delay treatment and negatively affect oncologic outcomes. In Crohn's patients, leaks are associated with higher recurrence rates. In essence, the lack of agreement on the definition of an anastomotic leak inhibits meaningful understand of its epidemiology, prevention, and treatment.

Abstract
AIM Anastomotic leakage (AL) after colon cancer (CC) and rectal cancer (RC) surgery often requires reintervention. Prevalence and morbidity may change over time with evolutions in treatment strategies and changes in patient characteristics. This nationwide study aimed to evaluate changes in the incidence, risk factors and mortality from AL during the past nine years. METHODS Data of CC and RC resections with primary anastomosis were extracted from the Dutch Colorectal Audit (2011-2019). AL was registered if requiring reintervention. Three consecutive cohorts were compared using logistic regression analysis. RESULTS Incidence of AL after CC surgery decreased from 6.6% in 2011-2013 to 4.8% in 2017-2019 and increased from 8.6% to 11.9% after RC surgery. In 2011-2013, male sex, ASA ≥3, (y)pT3-4, neoadjuvant therapy, emergency surgery and multivisceral resection were identified as risk factors for AL after CC surgery. In 2017-2019, only male sex and ASA ≥3 were risk factors for AL. For RC patients, male sex and neoadjuvant therapy were a risk factor for AL in 2011-2013. In 2017-2019, transanal approach was also a risk factor for AL. Postoperative mortality rate after AL was 12% (CC) and 2% (RC) in 2017-2019, without significant changes over time. CONCLUSION Contradictory trends in incidence and mortality for AL were observed among CC and RC surgery with changing risk factors over the past 9 years. High mortality after AL is only observed after CC surgery and remains unchanged. Continued efforts should be made to improve early detection and treatment of AL for these patients.

Abstract
BACKGROUND Anastomotic leakage (AL) is one of the dreaded complications following surgery in the digestive tract. Near-infrared fluorescence (NIRF) imaging is a means to intraoperatively visualize anastomotic perfusion, facilitating fluorescence image-guided surgery (FIGS) with the purpose to reduce the incidence of AL. The aim of this study was to analyze the current practices and results of NIRF imaging of the anastomosis in digestive tract surgery through the EURO-FIGS registry. METHODS Analysis of data prospectively collected by the registry members provided patient and procedural data along with the ICG dose, timing, and consequences of NIRF imaging. Among the included upper-GI, colorectal, and bariatric surgeries, subgroup analysis was performed to identify risk factors associated with complications. RESULTS A total of 1240 patients were included in the study. The included patients, 74.8% of whom were operated on for cancer, originated from 8 European countries and 30 hospitals. A total of 54 surgeons performed the procedures. In 83.8% of cases, a pre-anastomotic ICG dose was administered, and in 60.1% of cases, a post-anastomotic ICG dose was administered. A significant difference (p < 0.001) was found in the ICG dose given in the four pathology groups registered (range: 0.013-0.89 mg/kg) and a significant (p < 0.001) negative correlation was found between the ICG dose and BMI. In 27.3% of the procedures, the choice of the anastomotic level was guided by means of NIRF imaging which means that in these cases NIRF imaging changed the level of anastomosis which was first decided based on visual findings in conventional white light imaging. In 98.7% of the procedures, the use of ICG partly or strongly provided a sense of confidence about the anastomosis. A total of 133 complications occurred, without any statistical significance in the incidence of complications in the anastomoses, whether they were ICG-guided or not. CONCLUSION The EURO-FIGS registry provides an insight into the current clinical practice across Europe with respect to NIRF imaging of anastomotic perfusion during digestive tract surgery.

Abstract
Following pancreatoduodenectomy (PD), the modality of pancreato-enteric continuity restoration may impact on postoperative pancreatic fistula (POPF) risk. The aim of this study is to compare, among patients with soft pancreas and at moderate/high risk for POPF, the outcomes of PD with Pancreato-Gastrostomy (PG), versus Isolated Jejunal Loop Pancreato-Jejunostomy (IJL-PJ). 193 patients with a Callery Fistula Risk Score (C-FRS) ≥ 3 operated at 3 HPB Units, two performing PG and one IJL-PJ as their preferred anastomotic technique following PD (2009-2019) were included in this study (PG = 123, IJL-PJ = 70). Primary outcomes were POPF, clinically relevant (cr-)postoperative pancreatic hemorrhage (cr-PPH), delayed gastric emptying (cr-DGE), and postoperative major complications and mortality. POPF, cr-PPH, and cr-DGE occurred in 21.8%, 17.6%, and 11.4% of patients, and did not differ significantly between PG (26%, 19.5%, and 10.6%, respectively) and IJL-PJ (17.1%, 14.3%, and 12.9%, respectively; all p > 0.05) patients. Major (Dindo ≥ 3) complication and mortality rates were 26.4% and 3.3%, respectively, and did not differ significantly between PG (29.3% and 3.8%) and IJL-PJ (21.4% and 2.9) patients (p > 0.05). A faster surgical drain and nasogastric tube removal matched a significantly shorter hospitalization among IJL-PJ patients (median LOS: 18 days versus 25 days among PG patients, p < 0.001). In conclusion, IJL-PJ and PG, when performed by surgeons specialized with the concerned anastomotic technique in patients with soft pancreas and moderate/high risk for POPF, have similar results in terms of perioperative mortality and postoperative complications both overall and specific for PD.

Abstract
BACKGROUND The role of esophageal microbiota in esophageal cancer treatment is gaining renewed interest, largely driven by novel DNA-based microbiota analysis techniques. The aim of this systematic review is to provide an overview of current literature on the possible association between esophageal microbiota and outcome of esophageal cancer treatment, including tumor response to (neo)adjuvant chemo(radio)therapy, short-term surgery-related complications, and long-term oncological outcome. METHODS A systematic review of literature was performed, bibliographic databases were searched and relevant articles were selected by two independent researchers. The Newcastle-Ottawa scale was used to estimate the quality of included studies. RESULTS The search yielded 1303 articles, after selection and cross-referencing, five articles were included for qualitative synthesis and four studies were considered of good quality. Two articles addressed tumor response to neoadjuvant chemotherapy and described a correlation between high intratumoral Fusobacterium nucleatum levels and a poor response. One study assessed surgery-related complications, in which no direct association between esophageal microbiota and occurrence of complications was observed. Three studies described a correlation between shortened survival and high levels of intratumoral F. nucleatum, a low abundance of Proteobacteria and high abundances of Prevotella and Streptococcus species. CONCLUSIONS Current evidence points towards an association between esophageal microbiota and outcome of esophageal cancer treatment and justifies further research. Whether screening of the individual esophageal microbiota can be used to identify and select patients with a predisposition for adverse outcome needs to be further investigated. This could lead to the development of microbiota-based interventions to optimize esophageal microbiota composition, thereby improving outcome of patients with esophageal cancer.

Abstract
BACKGROUND AND OBJECTIVE Surgical drains are widely utilized in hepatopancreaticobiliary surgery to prevent intra-abdominal collections and identify postoperative complications. Surgical drain monitoring ranges from simple-output measurements to specific analysis for constituents such as amylase. This systematic review aimed to determine whether surgical drain monitoring can detect postoperative complications and impact on patient outcomes. METHODS A systematic review was performed, and the following databases searched between 02/03/20 and 26/04/20: MEDLINE, EMBASE, The Cochrane Library, and Clinicaltrials.gov. All studies describing surgical drain monitoring of output and content in adult patients undergoing hepatopancreaticobiliary surgery were considered. Other invasive methods of intra-abdominal sampling were excluded. RESULTS The search returned 403 articles. Following abstract review, 390 were excluded and 13 articles were included for full review. The studies were classified according to speciality and featured 11 pancreatic surgery and 2 hepatobiliary surgery studies with a total sample of 3262 patients. Postoperative monitoring of drain amylase detected pancreatic fistula formation and drain bilirubin testing facilitated bile leak detection. Both methods enabled early drain removal. Improved patient outcomes were observed through decreased incidence of postoperative complications (pancreatic fistulas, intra-abdominal infections, and surgical-site infections), length of stay, and mortality rate. Isolated monitoring of drain output did not confer any clinical benefits. CONCLUSIONS Surgical drain monitoring has advantages in the postoperative care for selected patients undergoing hepatopancreaticobiliary surgery. Enhanced surgical drain monitoring involving the testing of drain amylase and bilirubin improves the detection of complications in the immediate postoperative period.

Abstract
BACKGROUND Research has demonstrated a possible relation between patients' preoperative lifestyle and postoperative complications. OBJECTIVE This study aimed to assess associations between modifiable preoperative lifestyle factors and postoperative complications in patients undergoing elective surgery for colorectal cancer. DESIGN This is a retrospective study of a prospectively maintained database. SETTING At diagnosis, data on smoking habits, alcohol consumption, BMI, and physical activity were collected by using questionnaires. Postoperative data were gathered from the nationwide database of the Dutch ColoRectal Audit. PATIENTS Patients (n = 1564) with newly diagnosed stage I to IV colorectal cancer from 11 Dutch hospitals were included in a prospective observational cohort study (COLON) between 2010 and 2018. MAIN OUTCOME MEASURES Multivariable logistic regression models were used to identify which preoperative lifestyle factors were associated with postoperative complications. RESULTS Postoperative complications occurred in 28.5%, resulting in a substantially prolonged hospital stay (12 vs 5 days, p < 0.001). Independently associated with higher postoperative complication rates were ASA class II (OR, 1.46; 95% CI, 1.05-2.04; p = 0.03) and III to IV (OR, 3.17; 95% CI, 1.96-5.12; p < 0.001), current smoking (OR, 1.62; 95% CI, 1.02-2.56; p = 0.04), and rectal tumors (OR, 1.81; 95%CI, 1.28-2.55; p = 0.001). Body mass index, alcohol consumption, and physical activity did not show an association with postoperative complications. However, in a subgroup analysis of 200 patients with ASA III to IV, preoperative high physical activity was associated with fewer postoperative complications (OR, 0.17; 95% CI, 0.03-0.87; p = 0.04). LIMITATIONS Compared with most studied colorectal cancer populations, this study describes a relatively healthy study population with 87.2% of the included patients classified as ASA I to II. CONCLUSIONS Modifiable lifestyle factors such as current smoking and physical activity are associated with postoperative complications after colorectal cancer surgery. Current smoking is associated with an increased risk of postoperative complications in the overall study population, whereas preoperative high physical activity is only associated with a reduced risk of postoperative complications in patients with ASA III to IV.

De manera independiente se asociaron con mayores tasas de complicaciones posoperatorias la clasificación ASA II (OR 1,46; 95% IC 1,05-2,04, p = 0,03) y III-IV (OR 3,17; 95% IC 1,96-5,12, p <0,001), tabaquismo presente (OR 1,62; IC 95% 1,02-2,56, p = 0,04) y tumores rectales (OR 1,81; IC 95% 1,28-2,55, p = 0,001). El IMC, el consumo de alcohol y la actividad física no mostraron asociación con complicaciones posoperatorias. Sin embargo, en un análisis de subgrupos de 200 pacientes ASA III-IV, la actividad física íntensa preoperatoria se asoció con menos complicaciones posoperatorias (OR 0,17; IC del 95%: 0,03-0,87, p = 0,04).LIMITACIONES:En comparación con las poblaciones de cáncer colorrectal más estudiadas, este estudio incluyó una población relativamente sana con el 87,2% de los pacientes incluidos clasificados como ASA I-II.CONCLUSIONES:Los factores modificables del estilo de vida, como son el encontrarse fumando y la actividad física, se asocian con complicaciones posoperatorias después de la cirugía de cáncer colorrectal. El encontrarse fumando se asocia con un mayor riesgo de complicaciones posoperatorias en la población general del estudio, mientras que la actividad física íntensa preoperatoria se asocia con un menor riesgo de complicaciones posoperatorias únicamente en pacientes ASA III-IV.

A pilot study on prophylactic tube enterostomy for the prevention of anastomotic leakage in patients with high-risk intestinal anastomosis. Langenbecks Arch Surg 2021; 407:267-275. [PMID: 34549336 DOI: 10.1007/s00423-021-02326-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Accepted: 09/03/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Anastomotic leakages (ALs) are one of the most serious complications following gastrointestinal anastomosis. Currently, very few operative measures are available for the prevention of ALs. This pilot study aimed to evaluate the safety and efficacy of tube enterostomy (T-E) for the prevention of ALs in patients with high-risk intestinal anastomosis. METHODS In this retrospective study, demographic data and postoperative outcomes were compared among patients who received T-E and two historical cohorts: one group that underwent primary anastomosis without T-E (non-T-E group) and another that underwent conventional stoma construction without anastomosis (stoma group). The operative procedures were selected according to a scoring system that quantitatively evaluated risk of Als (Zhongnan score). RESULTS From March 2017 to March 2020, a total of 45 consecutive patients were enrolled in the T-E group. Among these patients, 53.3% (24/45) were diagnosed with Crohn's disease (CD), and 66.7% (30/45) of them underwent emergency surgery. After propensity score matching, the demographic data were comparable among the three groups. One case of AL (2.2%) occurred in the T-E group, while four cases of ALs (8.9%, 4/45) were found in the non-T-E group (p = 0.13). Tube feeding was provided to 33.3% (15/45) of the T-E patients. Major tube-related complications included one tube dislocation (2.2%) and 3 (6.7%) minor leakages after tube withdrawal (treated conservatively). One death occurred in the stoma group. In the subgroup analysis of CD patients, lower rates of ALs and abdominal abscesses were observed in the T-E group than in the non-T-E and stoma subgroups, but the differences were not significant. CONCLUSIONS T-E seems to be a safe and feasible operative method for the protection of high-risk intestinal anastomosis, can be reversed and can provide enteral feeding with acceptable tube-related complications. Further studies are needed to validate the role of T-E.

The Role of Heart Rate, Body Temperature, and Respiratory Rate in Predicting Anastomotic Leakage following Surgery for Rectal Cancer. Mediators Inflamm 2021; 2021:8698923. [PMID: 34456630 PMCID: PMC8390156 DOI: 10.1155/2021/8698923] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 08/06/2021] [Indexed: 11/17/2022] Open
Abstract
Objective To explore the value of the heart rate, body temperature, and respiratory rate in the early prediction of anastomotic leakage after rectal cancer surgery. Methods Clinical data from patients with rectal cancer who underwent anterior rectal resection in the Department of Gastroenterology, Renmin Hospital of Wuhan University, from January 2017 to December 2019 were collected and analyzed retrospectively. Based on the occurrence of anastomotic leakage after surgery, the patients were divided into two groups: those with and without anastomotic leakage. The quantitative values of the heart rate, body temperature, and respiration rate at day 7 postsurgery were compared between the two groups. The ROC curve was used to analyze their role in the early prediction of anastomotic leakage. Results Among 441 patients with rectal cancer, 30 (6.81%) had clinical anastomotic leakage and were diagnosed at 7 ± 3 days postsurgery. Within 7 days postsurgery, the heart rate, body temperature, and respiratory rate in the anastomotic leakage group were higher than those in the nonanastomotic leakage group. The differences in heart rate (1-5 d), body temperature (2-7 d), and respiratory rate (1-7 d) were statistically significant (P < 0.05). The three ROC curves were drawn, respectively. The predictive value of the heart rate is greatest at days 2-3 postsurgery. The predictive value of the body temperature is greatest at days 4-6 postsurgery. The predictive value of the respiratory rate is best at days 1-4 postsurgery. Conclusion The changes of vital signs (heart rate, body temperature, and respiratory rate) have a certain value in the early prediction of anastomotic leakage after rectal cancer surgery. Observation of postoperative vital signs at 7 days postsurgery is helpful for the early diagnosis of anastomotic leakage.
