Bioresorbable shape-adaptive structures for ultrasonic monitoring of deep-tissue homeostasis. Science 2024; 383:1096-1103. [PMID: 38452063 DOI: 10.1126/science.adk9880] [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: 09/21/2023] [Accepted: 01/12/2024] [Indexed: 03/09/2024]
Abstract
Monitoring homeostasis is an essential aspect of obtaining pathophysiological insights for treating patients. Accurate, timely assessments of homeostatic dysregulation in deep tissues typically require expensive imaging techniques or invasive biopsies. We introduce a bioresorbable shape-adaptive materials structure that enables real-time monitoring of deep-tissue homeostasis using conventional ultrasound instruments. Collections of small bioresorbable metal disks distributed within thin, pH-responsive hydrogels, deployed by surgical implantation or syringe injection, allow ultrasound-based measurements of spatiotemporal changes in pH for early assessments of anastomotic leaks after gastrointestinal surgeries, and their bioresorption after a recovery period eliminates the need for surgical extraction. Demonstrations in small and large animal models illustrate capabilities in monitoring leakage from the small intestine, the stomach, and the pancreas.

The Effectiveness of Adipose Tissue-Derived Mesenchymal Stem Cells Mixed with Platelet-Rich Plasma in the Healing of Inflammatory Bowel Anastomoses: A Pre-Clinical Study in Rats. J Pers Med 2024; 14:121. [PMID: 38276243 PMCID: PMC10817310 DOI: 10.3390/jpm14010121] [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: 12/12/2023] [Revised: 12/22/2023] [Accepted: 12/25/2023] [Indexed: 01/27/2024] Open
Abstract
Introduction: Multiple factors have been linked with increased risk of anastomotic leak in bowel surgery, including infections, inflammatory bowel disease, patient comorbidities and poor surgical technique. The aim of this study was to investigate the positive effect, if any, of adipose derived mesenchymal stem cells (MSCs) mixed with platelet-rich plasma (PRP) in the healing of bowel anastomoses, in an inflammatory environment after establishment of experimental colitis. Materials and Methods: Thirty-five male Wistar rats were divided into five groups of seven animals: normal controls, colitis controls, PRP, MSCs, and PRP+MSCs. All groups underwent laparotomy, one-cm segmental colectomy and anastomosis in situ. In the colitis group, colectomy was performed at the affected area. Colitis was previously established by transrectal administration of 2,4,6-trinitrobenzene sulfonic acid (TNBS) except for the normal controls. Post-mortem histopathological, tissue hydroxyproline and anastomotic bursting pressure (ABP) assessments were performed. The Mann-Whitney U test was used to assess statistical significance differences between groups. Results: No perioperative mortality was noted. Tissue hydroxyproline and ABP were significantly increased in the group of PRP+MSCs compared to colitis controls (p = 0.0151 and p = 0.0104, respectively). Inflammatory cell infiltration was lower and fibroblast activity higher in PRP+MSCs group, but not statistically significant (p > 0.05). Neoangiogenesis (p = 0.0073) and anastomotic area epithelialization (p = 0.0182) were significantly higher in PRP + MSCs group compared to colitis controls. Discussion: The synergistic effect of the PRP and MSCs is apparently responsible for the improved healing markers in bowel anastomoses even on inflammatory bowel. This gives hope for primary anastomoses and stoma saving in many emergency and/or elective circumstances, especially in immunocompromised or malnourished patients, even in cases with inflammation or peritonitis. Clinical studies should follow in order to support the clinical application of PRP+MSCs in gastrointestinal anastomoses.

Abstract
Pancreatic surgery is considered one of the most technically challenging surgical procedures, despite the evolution of modern techniques. Neoplasms remain the most common indication for pancreatic surgery, although inflammatory conditions may also prompt surgical evaluation. The choice of surgical procedure depends on the type and location of the pathologic finding because different parts of the pancreas have separate vascular supplies that may be shared by adjacent organs. The surgical approach could be conventional or minimally invasive (laparoscopic, endoscopic, or robotic assisted). Because of the anatomic complexity of the pancreatic bed, perioperative complications may be frequently encountered and commonly involve the pancreatic-biliary, vascular, lymphatic, or bowel systems, irrespective of the surgical technique used. Imaging plays an important role in the assessment of suspected postoperative complications, with CT considered the primary imaging modality, while MRI, digital subtraction angiography, and molecular imaging are considered ancillary diagnostic tools. Accurate diagnosis of postoperative complications requires a solid understanding of pancreatic anatomy, surgical indications, normal postoperative appearance, and expected postsurgical changes. The practicing radiologist should be familiar with the most common perioperative complications, such as anastomotic leak, abscess, and hemorrhage, and be able to differentiate these entities from normal anticipated postoperative changes such as seroma, edema and fat stranding at the surgical site, and perivascular soft-tissue thickening. In addition to evaluation of the primary operative fossa, imaging plays a fundamental role in assessment of the adjacent organ systems secondarily affected after pancreatic surgery, such as vascular, biliary, and enteric complications.

Efficacy of Biomarkers in Predicting Anastomotic Leakage After Gastrointestinal Resection: A Systematic Review and Meta-Analysis. Cureus 2023; 15:e50370. [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.

Biologic use is not associated with postoperative complications in patients with Crohn's disease undergoing stoma reversion. ANZ J Surg 2023; 93:2921-2927. [PMID: 38041216 DOI: 10.1111/ans.18790] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 11/01/2023] [Accepted: 11/12/2023] [Indexed: 12/03/2023]
Abstract
PURPOSE Stoma creation is a common procedure in patients with Crohn's disease (CD), and early prophylaxis with biologics is recommended for high-risk patients. However, the effect of biologic exposure on morbidity after stoma closure remains unknown. Therefore, this study aimed to investigate the impact of biologic use on the occurrence of complications in CD patients following stoma closure. METHODS Consecutive patients diagnosed with CD who underwent ileostomy reversal at a tertiary care centre between 1 January 2013 and 1 December 2021, were included in the study. The primary outcome was the occurrence of 90-day postoperative complications. RESULTS The study included 347 eligible patients who underwent ileostomy reversal. There was no significant difference in terms of infectious complications, overall complications or length of postoperative stay between the biologic and non-biologic groups. Multivariate logistic regression analysis identified several predictors of postoperative morbidity, including preoperative haemoglobin levels below 100 g/L, CRP levels above 10 mg/L, anastomotic site, ileostomy-related infectious complications and albumin levels below 35 g/L. CONCLUSIONS This study demonstrated that the use of biologics is not associated with adverse outcomes. However, such as high CRP levels, ileostomy-related infectious complications, hypoproteinemia, and hemoglobinemia, should be optimized prior to surgery to reduce postoperative morbidities.

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.

Application of indocyanine green in surgery: A review of current evidence and implementation in trauma patients. World J Gastrointest Surg 2023; 15:757-775. [PMID: 37342859 PMCID: PMC10277941 DOI: 10.4240/wjgs.v15.i5.757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Revised: 01/18/2023] [Accepted: 03/27/2023] [Indexed: 05/26/2023] Open
Abstract
Background: Modern surgical medicine strives to manage trauma while improving outcomes using functional imaging. Identification of viable tissues is crucial for the surgical management of polytrauma and burn patients presenting with soft tissue and hollow viscus injuries. Bowel anastomosis after trauma-related resection is associated with a high rate of leakage. The ability of the surgeon’s bare eye to determine bowel viability remains limited, and the need for a more standardized objective assessment has not yet been fulfilled. Hence, there is a need for more precise diagnostic tools to enhance surgical evaluation and visualization to aid early diagnosis and timely management to minimize trauma-associated complications. Indocyanine green (ICG) coupled with fluorescence angiography is a potential solution for this problem. ICG is a fluorescent dye that responds to near-infrared irradiation. Methods: We conducted a narrative review to address the utility of ICG in the surgical management of patients with trauma as well as elective surgery. Discussion: ICG has many applications in different medical fields and has recently become an important clinical indicator for surgical guidance. However, there is a paucity of information regarding the use of this technology to treat traumas. Recently, angiography with ICG has been introduced in clinical practice to visualize and quantify organ perfusion under several conditions, leading to fewer cases of anastomotic insufficiency. This has great potential to bridge this gap and enhance the clinical outcomes of surgery and patient safety. However, there is no consensus on the ideal dose, time, and manner of administration nor the indications that ICG provides a genuine advantage through greater safety in trauma surgical settings. Conclusions: There is a scarcity of publications describing the use of ICG in trauma patients as a potentially useful strategy to facilitate intraoperative decisions and to limit the extent of surgical resection. This review will improve our understanding of the utility of intraoperative ICG fluorescence in guiding and assisting trauma surgeons to deal with the intraoperative challenges and thus improve the patients’ operative care and safety in the field of trauma surgery.

Abstract
INTRODUCTION Up to the present time, the laparoscopic approach for colon cancer is considered the gold standard. However, robotic surgery has been appraised in modern medicine. It is essential to evaluate the differences between laparoscopic and robotic surgery, owing to the significant impact they cause in postoperative morbidity and mortality. This article aims to perform a systematic review and meta-analysis of the literature to compare robotic versus laparoscopic colectomies in patients with colon cancer in terms of the incidence of colonic fistulas. METHODS AND ANALYSIS PubMed, Embase, Scopus, Web of Science, Science Direct, Cochrane Central Register of Controlled Trials, CINAHL, LILACS and Clinical trials databases will be searched for randomised clinical trials investigating the incidence of colonic fistulas in patients with colonic cancer, submitted to robotic surgery compared with a laparoscopic approach. No language or publication period restrictions will be imposed. The primary outcome will be the incidence of colonic fistulas in patients with colon cancer in different surgical approaches. The secondary outcomes will be the incidence of infection, sepsis, mortality, length of hospitalisation and malnutrition. Three independent reviewers will select the studies and extract data from the original publications. The risk of bias will be assessed using The Risk of Bias 2 tool, and the evidence's certainty will be made using the Grading of Recommendations Assessment, Development and Evaluation. Data synthesis will be performed using the Review Manager software (RevMan V.5.2.3). To assess heterogeneity. We will compute the I2 statistics. In addition, a quantitative synthesis will be performed if the included studies are sufficiently homogeneous. ETHICS AND DISSEMINATION This study will review the published data; thus, it is not necessary to obtain ethical approval. The findings of this systematic review will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42021295313.

Abstract
This study evaluated the effects of perioperative nutrition management by a multidisciplinary team on nutrition and postoperative complications of patients with esophageal cancer. A total of 239 patients with esophageal cancer who underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between February 2019 and February 2020 were included in the study. They were divided into the experimental group (120 patients) and the control group (119 patients) using the random number table method. Control group patients received routine diet management and experimental group patients received perioperative nutrition management by a multidisciplinary team. The differences of nutriture and postoperative complications between the two groups were compared. At 3 and 7 days after surgery, the experimental group patients had higher total protein and albumin levels (P<0.05), shorter postoperative anal exhaust time (P<0.05), lower incidence of postoperative gastrointestinal adverse reactions, pneumonia, anastomotic fistula, hypoproteinemia (P<0.05), and lower hospitalization costs (P<0.05) than the control group. Nutrition management by a multidisciplinary team effectively improved the nutriture of patients, promoted the rapid recovery of postoperative gastrointestinal function, reduced postoperative complications, and reduced hospitalization costs.

High amylase concentration in drainage liquid can early predict proximal and distal intestinal anastomotic leakages: A prospective observational study. JOURNAL OF RESEARCH IN MEDICAL SCIENCES 2023; 28:5. [PMID: 36974108 PMCID: PMC10039101 DOI: 10.4103/jrms.jrms_273_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 04/14/2021] [Accepted: 06/09/2022] [Indexed: 02/03/2023]
Abstract
Background Anastomotic leak (AL) is a serious complication in digestive surgery. Early diagnosis might allow clinicians to anticipate appropriate management. The aim of this study was to assess the predictive value of amylase concentration in drain fluid for the early diagnosis of digestive tract AL. Materials and Methods Hundred and fourteen consecutive patients "at risk" of AL, in whom a flexible drainage was placed by surgeon's choice after digestive anastomosis were included. Patients with eso-gastric, bilio-digestive, and pancreatic anastomoses were excluded. Drain amylase measurement (DAM) was routinely performed on postoperative day (POD) 1, 3, 5-7. DAM values were compared between patients with postoperative AL versus patients without AL. A receiver-operating curve (ROC) with calculation of the areas under the ROC curves area under curves was performed and a cutoff value of DAM was calculated. Results AL occurred in 25 patients (AL group) and 89 patients did not present AL (C group). The mean DAM was significantly higher in AL group versus C Group on POD 1, 3, and 5. A cutoff value of 307 IU/L predicted the occurrence of AL with a sensitivity and specificity of 91% and 100%, respectively. Positive and negative predictive values were 100% and 97.5%, respectively. Patients with AL had an elevated DAM prior to the appearance of any clinical signs of AL. Conclusion High level DAM could accurately predict AL for proximal and distal digestive tract anastomoses. This simple, noninvasive, and low-cost method can accurately predict early AL and help physicians to perform appropriate imaging and treatment.

Abstract
Intestinal suture dehiscence is one of the most feared complications following gastrointestinal surgery in both human and veterinary medicine, increasing the morbidity and mortality of these patients. Clinical and laboratory early signs of septic peritonitis are not always easily identifiable while prompt treatment should help decrease postoperative morbidity and mortality. The aim of this study is to describe the ultrasonographic (US) features of confirmed leakage of intestinal sutures (LIS) and to evaluate if this imaging technique can be useful as noninvasive tool for the early diagnosis of LIS. Seven dogs developed LIS in a range of three-four days after gastrointestinal surgery and four of these developed a second dehiscence. On B-mode ultrasonography, all intestinal surgical sites were identified and characterized by a bowel focal thickening with reduced or absent wall layering and the presence of hyperechoic, double-walled foci at regular intervals (suture material). Furthermore, hyperechoic linear interfaces associated with dirty acoustic shadowing and comet-tail artifacts crossing the intestinal wall to free-float in peritoneal cavity or in a saccate collection have been documented. On the basis of these preliminary results, canine abdominal ultrasound seems to be a useful diagnostic technique for post-operative monitoring of patients undergoing intestinal surgery, allowing early detection of signs of a LIS, before the patient develops clinical signs of septic peritonitis.

Abstract
AIM Anastomotic leak results in increased morbidity and affects functional and oncological outcomes after colectomy. Measurement of C-reactive protein (CRP) allows early detection of anastomotic leaks. The aim of this study was to evaluate the benefit to the patient of earlier diagnosis and management of anastomotic leaks, namely avoiding takedown of the anastomosis. METHOD Patients with an anastomotic fistula after elective colorectal surgery from 2010 to 2020 were included. Three periods were defined according to progressive adherence to the CRP protocol in our department. A comparison was made between the periods 'before' (2010-2013) and 'after' (2016-2020) in terms of morbidity, mortality, anastomotic salvage, days spent in hospital within the first postoperative month, timely adjuvant chemotherapy and anastomotic stenosis. RESULTS Out of 2655 elective colorectal operations, 171 patients presented with an anastomotic leak and 123 patients were included in the study. In univariate analysis, patients in the 'after' group had fewer severe complications (Clavien-Dindo Grade III to IV, 66.7% vs. 56.9; p = 0.017); the difference did not reach significance regarding timely postoperative chemotherapy (p = 0.058) and anastomotic stenosis (p = 0.682). In both, univariate and multivariate analysis, the 'after' period increased the chances of preserving the anastomosis (OR = 2.37 [1.08-5.17]) and increased the number of days out of hospital (p = 0.0002). CONCLUSION A CRP-based protocol for the screening of anastomotic leaks after colorectal surgery was related to increased anastomotic conservation, a decreased impact and severity of the leak and a shorter length of hospital stay.

Abstract
We report a rare case of spontaneous biliary pleural fistula in a patient whose diagnosis was aided by the use of near-infrared I/II fluorescence imaging. When both 99mTc-mebrofenin hepatobiliary scintigraphy and CT examination were diagnostically difficult, we found strong fluorescent signals in the patient’s pleural drainage fluid and sputum using NIR I/II fluorescence imaging, and therefore diagnosed the patient with a biliary pleural fistula. This provides a safe and effective test for diagnosing biliary pleural fistulas.

Abstract
Background The efficacy of enteral immunonutrition (EIN) in patients undergoing gastrointestinal cancer surgery remains debatable. This meta-analysis aimed to investigate the effectiveness of EIN administration in patients undergoing surgery for gastrointestinal cancer. Methods From January 2000 to January 2022, PubMed, EMBASE, Cochrane Library, and Web of Science were thoroughly searched for randomized controlled trials (RCTs) with EIN versus standard diet or no supplement in patients undergoing surgery for gastrointestinal cancer. Overall complications and infectious complications were the primary outcomes. The secondary results were non-infectious complications, mortality, length of hospital stay, and enteral nutrition-related complications. Results Thirty-five studies reporting 3,692 patients undergoing surgery for gastrointestinal cancer (including gastric cancer, colorectal cancer, esophageal cancer, periampullary cancer, or pancreatic cancer) were included. Compared with the control group, EIN group had a significantly decreased incidence of overall complications (RR = 0.79, p < 0.001). Infectious complications in patients who received EIN were considerably lower than in the control group (RR = 0.66, p < 0.001). Compared to the control group, the incidence of surgical site infection, abdominal abscess, anastomotic leakage, bacteremia, duration of systemic inflammatory response syndrome (SIRS), and duration of antibiotic therapy was significantly lower in the specific infectious complications treated with EIN. Still, there was no significant difference between the two groups with other infectious complications. Moreover, a substantial shortening in the length of hospital stay was shown in EIN group compared with the control group. Still, no significant effect of EIN was demonstrated in non-infectious complicatios and mortality. The enteral nutrition-related complications had no significant difference between two groups. Conclusions EIN is safe and effective in reducing overall complications, infectious complications, and hospital stay in patients undergoing gastrointestinal cancer surgery (including gastric cancer, colorectal cancer, esophageal cancer, periampullary cancer, or pancreatic cancer).

Abstract
Introduction Among the many possible postoperative complications, anastomotic leakage (AL) is the most common and serious. Therefore, the purpose of this study was to explore the ability of various inflammatory and nutritional markers to predict postoperative AL in patients after esophagectomy. Methods A total of 273 patients were retrospectively evaluated and enrolled into this study. Perioperative, surgery-related, tumor-related and laboratory tests data were extracted and analyzed. The discriminatory ability and optimal cut-off value was evaluated according to the receiver operating characteristic (ROC) curve analysis. Univariate and multivariate analyses were performed to access the potential risk factors for AL. Results The overall incidence of AL was 12.5% (34/273). C-reactive protein-to-albumin ratio (CRP/ALB ratio) [AUC 0.943 (95% confidence interval (CI) = 0.911–0.976, p < 0.001)] and operation time [AUC 0.747 (95% CI = 0.679–0.815, p < 0.001)] had the greatest discrimination on AL prediction. Multivariate analysis demonstrated that CRP/ALB ratio and operation time were two independent risk factors for AL, and CRP/ALB ratio (OR = 102.909, p < 0.001) had an advantage over operation time (OR = 9.363, p = 0.020; Table 3). Conclusion Operation time and postoperative CRP/ALB ratio were two independent predictive indexes for AL. Postoperative CRP/ALB ratio greater than 3.00 indicated a high risk of AL. For patients with abnormal postoperative CRP/ALB ratio, early non-operative treatment or surgical intervention are needed to reduce the serious sequelae of AL.

Preliminary application of indocyanine green fluorescence imaging in postoperative gastrointestinal fistula. Photodiagnosis Photodyn Ther 2021; 34:102336. [PMID: 33965600 DOI: 10.1016/j.pdpdt.2021.102336] [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: 01/13/2021] [Revised: 03/24/2021] [Accepted: 05/03/2021] [Indexed: 10/21/2022]
Abstract
We describe a case using indocyanine green (ICG) fluorescence imaging for diagnosis of postoperative gastrointestinal fistula. When the fistula is very large, both indocyanine green and methylene blue can be found in the postoperative drainage. After treatment, when the leak became small, only ICG fluorescence imaging continued to be demonstrated. ICG fluorescence imaging is likely to prove to be a safe and effective method of examination, and one that is very practical and easy to execute for the diagnosis of postoperative gastrointestinal fistula.

Abstract
Extracellular vesicles (EVs), especially from stem/stromal cells (SCs), represent a cell-free alternative in regenerative medicine holding promises to promote tissue healing while providing safety and logistic advantages in comparison to cellular counterparts. Herein, we hypothesize that SC EVs, administered locally in a thermoresponsive gel, is a therapeutic strategy for managing post-surgical colo-cutaneous fistulas. This disease is a neglected and challenging condition associated to low remission rates and high refractoriness. Herein, EVs from a murine SC line were produced by a high-yield scalable method in bioreactors. The post-surgical intestinal fistula model was induced via a surgical cecostomy communicating the cecum and the skin in Wistar rats. Animals were treated just after cecostomy with PBS, thermoresponsive Pluronic F-127 hydrogel alone or containing SC EVs. A PET-monitored biodistribution investigation of SC EVs labelled with 89Zr was performed. Fistula external orifice and output assessment, probe-based confocal laser endomicroscopy, MRI and histology were carried out for therapy follow-up. The relevance of percutaneous EV administration embedded in the hydrogel vehicle was indicated by the PET-biodistribution study. Local administration of SC EVs in the hydrogel reduced colo-cutaneous fistula diameter, output, fibrosis and inflammation while increasing the density of neo-vessels when compared to the PBS and gel groups. This multi-modal investigation pointed-out the therapeutic potential of SC EVs administered locally and in a thermoresponsive hydrogel for the management of challenging post-surgical colon fistulas in a minimally-invasive cell-free strategy.

C-Reactive Protein-Lymphocyte Ratio Identifies Patients at Low Risk for Major Morbidity after Oesophagogastric Resection for Cancer. Dig Surg 2020; 37:515-523. [PMID: 33105139 DOI: 10.1159/000510963] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Accepted: 08/17/2020] [Indexed: 12/13/2022]
Abstract
INTRODUCTION Complications following oesophagogastric surgery have significant implications for patient recovery. OBJECTIVE identify cost-effective biomarkers which can predict morbidity. METHODS Analysis of all upper gastrointestinal resections in Galway University Hospital from 2014 to 2018 was performed. The ability of C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR), and CRP-lymphocyte ratio (CLR) to predict morbidity, including anastomotic leak (AL), was assessed and compared. RESULTS Seventy-one oesophagectomies and 77 gastrectomies were performed. There were 2 (1%) 30-day mortalities and 83 (56%) morbidities of which 30 (20%) were of Clavien-Dindo grade 3 or higher. The rate of major morbidity within the oesophagectomy cohort was 27% and was 14% in the gastrectomy cohort. There were 11 (7%) ALs, 7 in the oesophagectomy cohort, and 4 in the gastrectomy cohort. From post-operative day (POD) 2 onwards, CRP could predict AL (POD2 AUC = 0.705, p = 0.025; POD3 AUC = 0.757, p = 0.005, POD4 AUC = 0.811, p = 0.001; and POD5 AUC = 0.824, p = 0.001). CLR predicted AL on POD2 onwards (POD2 AUC = 0.722, p = 0.005; POD3 AUC = 0.736, p = 0.01; POD4 AUC = 0.775, p = 0.003; and POD5 AUC = 0.817, p = 0.001). CRP level of 218 mg/dL and CLR level of 301 at POD 2 generated negative predictive values of 97 and 98%, respectively, for AL. Post-operative NLR did not display sufficient discriminatory ability for the outcomes. CONCLUSION CRP and CLR are reliable negative predictors of major morbidity, including AL, after oesophagogastric resection. Their use can inform patient intervention and recovery.

Late rectal anastomotic leakage treated with diode laser FiLaC probe. A case report of a new minimal invasive treatment. Int J Surg Case Rep 2020; 77S:S132-S134. [PMID: 33041258 PMCID: PMC7876918 DOI: 10.1016/j.ijscr.2020.09.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 09/02/2020] [Accepted: 09/03/2020] [Indexed: 02/07/2023] Open
Abstract
Anastomotic leak is a common and potentially dangerous postoperative complication in colo-rectal surgery. Low anastomotic leak conservative treatment requires five months or more for a complete resolution and a complex management. The FiLaC laser diode technology could be a good option to reduce the healing time and to minimize patient’s discomfort.
Introduction Anastomotic Leakage (AL) is one of the most important early postoperative complication of the adenocarcinoma’s surgical treatment. Fistula Laser Closure (FiLaC®) is a minimal invasive technique that use diode laser energy to obtain the fistula track obliteration and it is finding large application for other affection characterized by fistula tracts presence. Presentation of case A 56 years old male, with no clinical history of adenocarcinoma in his family, underwent a laparoscopic low anterior resection with ileostomy for a rectal adenocarcinoma. Approximately 3 months after the procedure an anastomotic leak with an associated abscess was found. The patient underwent an endoscopic FiLaC off-label procedure on the AL and after further 4 months, he obtained a complete resolution of the anastomosis dehiscence. Discussion The literature is poor about the minimal invasive AL treatment and there is no paper about the management of the AL with the FiLaC® procedure. For asymptomatic patients a conservative solution is preferred, it could be considered a drain positioning for emptying abscesses and for irrigation or the use of an Endosponge to decrease the resolution time. The FiLaC® procedure could be a more feasible technique that could also reduce the healing time as well with no discomfort for the patient. Conclusion Considering the results and our patient healing time, we think that an off-label application of FiLaC® procedure on asymptomatic low anastomotic leak could be an opportunity for a morbidity resolution shorter than the simple wait and see strategy, and more sustainable for the patient.

Abstract
Since esophagojejunostomy leak (EJL) after gastrectomy is a potentially fatal complication and may impact the survival of patients with advanced gastric cancer (GC), it is important to establish risk factors for the EJL and to prevent this surgical complication. The aim of this study was analysis of predictors for the postoperative clinically apparent EJL. All patients operated for advanced GC between October 2016 and December 2019 were analyzed from a prospectively maintained database. The evaluation of the EJL and postoperative complications according to the demographic and clinical (categorized) variables was performed with odds ratio test (multivariate analysis was performed with the use of logistic regression method). Among the 114 patients included in the study, 71.1% received neoadjuvant chemotherapy and 19.3% underwent gastrectomy followed by the hyperthermic intraperitoneal chemotherapy (HIPEC). Postoperative EJL was found in 4.6% patients. The risk of EJL was significantly higher for mixed-type GC (OR = 12.45, 95% CI: 1.03-150.10; p = 0.0472). The risk of other postoperative complications was significantly higher in patients undergoing HIPEC (OR = 3.88, 95% CI: 1.40-10.80, p = 0.0094). The number of lymph nodes removed (>38) was characterized by 80% sensitivity and 79.6% specificity in predicting EJL (AUC = 0.80, 95% CI: 0.72-0.87; p < 0.0001). Mixed histological type of GC is a tumor-related risk factor for the EJL. HIPEC was confirmed to be a risk factor for postoperative complications after gastrectomy.

Enteral versus parenteral nutrition in the conservative treatment of upper gastrointestinal fistula after surgery: a multicenter, randomized, parallel-group, open-label, phase III study (NUTRILEAK study). Trials 2020; 21:448. [PMID: 32487210 PMCID: PMC7265255 DOI: 10.1186/s13063-020-04366-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Accepted: 05/05/2020] [Indexed: 11/10/2022] Open
Abstract
Background Postoperative upper gastrointestinal fistula (PUGIF) is a devastating complication, leading to high mortality (reaching up to 80%), increased length of hospital stay, reduced health-related quality of life and increased health costs. Nutritional support is a key component of therapy in such cases, which is related to the high prevalence of malnutrition. In the prophylactic setting, enteral nutrition (EN) is associated with a shorter hospital stay, a lower incidence of severe infectious complications, lower severity of complications and decreased cost compared to total parenteral nutrition (TPN) following major upper gastrointestinal (GI) surgery. There is little evidence available for the curative setting after fistula occurrence. We hypothesize that EN increases the 30-day fistula closure rate in PUGIF, allowing better health-related quality of life without increasing the morbidity or mortality. Methods/design The NUTRILEAK trial is a multicenter, randomized, parallel-group, open-label phase III trial to assess the efficacy of EN (the experimental group) compared with TPN (the control group) in patients with PUGIF. The primary objective of the study is to compare EN versus TPN in the treatment of PUGIF (after esophagogastric resection including bariatric surgery, duodenojejunal resection or pancreatic resection with digestive tract violation) in terms of the 30-day fistula closure rate. Secondary objectives are to evaluate the 6-month postrandomization fistula closure rate, time of first fistula closure (in days), the medical- and surgical treatment-related complication rate at 6 months after randomization, the fistula-related complication rate at 6 months after randomization, the type and severity of early (30 days after randomization) and late fistula-related complications (over 30 days after randomization), 30-day and 6-month postrandomization mortality rate, nutritional status at day 30, day 60, day 90 and day 180 postrandomization, the mean length of hospital stay, the patient’s health-related quality of life (by self-assessment questionnaire), oral feeding time and direct costs of treatment. A total of 321 patients will be enrolled. Discussion The two nutritional supports are already used in daily practice, but most surgeons are reluctant to use the enteral route in case of PUGIF. This study will be the first randomized trial testing the role of EN versus TPN in PUGIF. Trial registration ClinicalTrials.gov: NCT03742752. Registered on 14 November 2018.

Abstract
BACKGROUND The indications and efficacy of endoluminal vacuum therapy for the management of colorectal/coloanal anastomotic leakage are not well defined. OBJECTIVE This study aimed to evaluate the efficacy and to define adequate indications of endoluminal vacuum therapy to treat colorectal/coloanal anastomotic leakage. DESIGN The retrospective cohort evaluated in this study is based on a prospectively maintained database. SETTINGS This study was conducted in 8 centers from the French GRECCAR study group. PATIENTS Patients with colorectal/coloanal anastomotic leakage treated with endoluminal vacuum therapy were included. MAIN OUTCOME MEASURES The primary outcome measured was the success rate of endoluminal vacuum therapy defined by the complete healing of the perianastomotic sepsis and a functional anastomosis. The predictive factors of success of endoluminal vacuum therapy and long-term functional result (low anterior resection syndrome score) were also analyzed. RESULTS Among 62 patients treated for an anastomotic leakage of colorectal/coloanal anastomosis from 2012 to 2017, 47 fulfilled the inclusion criteria. The patients had a mean of 6.6 (±5.8) replacements for a total of 27 (±34) days treatment duration, associated with diverting stoma in 81%. After 37 months median follow-up, a successful treatment of anastomotic leakage using endoluminal vacuum therapy could be achieved in 26 patients (55%). The success rate was improved in patients undergoing primary endoluminal vacuum therapy compared to salvage endoluminal vacuum therapy (73% vs 33%, p = 0.006) and when endoluminal vacuum therapy was initiated within 15 days compared to more than 15 days after the diagnosis of anastomotic leakage (72.4% vs 27.8%, p = 0.003). At 12 months, 53% of patients who responded had minor low anterior resection syndrome and only 3 necessitated anastomotic stricture dilation. LIMITATIONS This was a noncomparative cohort study. CONCLUSION Endoluminal vacuum therapy appears to be effective to treat colorectal anastomotic leakage especially when it is used as primary treatment of the fistula. Long-term functional outcome of patients undergoing conservative management of anastomotic leakage may be improved with endoluminal vacuum therapy.

Abstract
Esophagectomy is a mainstay in curative treatment for esophageal cancer; however, the reported techniques and outcomes can vary greatly. Thirty-day mortality of patients with an intact anastomosis is 2-3% as compared to 17-35% in patients who have an anastomotic leak. The subsequent management of leaks postesophagectomy has great global variability with little consensus on a gold standard of practice. The aim of this multicentre prospective audit is to analyze current techniques of esophagogastric anastomosis to determine the effect on the anastomotic leak rate. Leak rates and leak management will be assessed to determine their impact on patient outcomes. A 12-month international multicentre prospective audit started in April 2018 and is coordinated by a team from the West Midlands Research Collaborative. This will include patients undergoing esophagectomy over 9 months and encompassing a 90-day follow-up period. A pilot data collection period occurred at four UK centers in 2017 to trial the data collection form. The audit standards will include anastomotic leak and the conduit necrosis rate should be less than 13% and major postoperative morbidity (Clavien-Dindo Grade III or more) should be less than 35%. The 30-day mortality rate should be less than 5% and the 90-day mortality rate should be less than 8%. This will be a trainee-led international audit of esophagectomy practice. Key support will be given by consultant colleagues and anesthetists. Individualized unit data will be distributed to the respective contributing sites. An overall anonymized report will be made available to contributing units. Results of the audit will be published in peer-reviewed journals with all collaborators fully acknowledged. The key information and results from the audit will be disseminated at relevant scientific meetings.

Abstract
Anastomotic leakage (AL) following gastroesophageal cancer surgery remains a serious postoperative complication. This systematic review aims to provide an overview of investigated biomarkers for the early detection of AL following esophagectomy, esophagogastrectomy and gastrectomy. All published studies evaluating the diagnostic accuracy of biomarkers predicting AL following gastroesophageal resection for cancer were included. The Embase, Medline, Cochrane Library, PubMed and Web of Science databases were searched. Risk of bias and applicability were assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) 2 tool. Twenty-four studies evaluated biomarkers in the context of AL following gastroesophageal cancer surgery. Biomarkers were derived from the systemic circulation, mediastinal and peritoneal drains, urine and mediastinal microdialysis. The most commonly evaluated serum biomarkers were C-reactive protein and leucocytes. Both proved to be useful markers for excluding AL owing to its high specificity and negative predictive values. Amylase was the most commonly evaluated peritoneal drain biomarker and significantly elevated levels can predict AL in the early postoperative period. The associated area under the receiver operating characteristic (AUROC) curve values ranged from 0.482 to 0.994. Current biomarkers are poor predictors of AL after gastroesophageal cancer surgery owing to insufficient sensitivity and positive predictive value. Further research is needed to identify better diagnostic tools to predict AL.

Abstract
Gastric cancer surgery has evolved considerably over the past years, with substantial improvement on outcomes. Meanwhile, esophagojejunal anastomotic fistula (EJF) continues to impair postoperative results. This study aimed to assess EJF regarding its incidence, risk factors, management and the impact on overall survival. We retrospectively analyzed 258 consecutive patients who underwent total or completion gastrectomy for GC from 2009 and 2017. Clinicopathological characteristics analysis was performed comparing patients who developed EJF with patients with other clinical or surgical complications, as well as patients without any postoperative complications. Fifteen (5.8%) patients had EJF and 81 (31.4%) had other complications (including other surgical fistulas). The median time of EJF diagnosis was on the eighth postoperative day (range 3-76). Completion gastrectomy (p = 0.048) and longer hospital stay (p < 0.001) were associated with the occurrence of EJF. The surgical mortality of patients with EJF was higher than in non-EJF patients (26.7% vs. 4.5%; p < 0.001). Nine patients were treated conservatively and six required surgery. The mortality rate of EJF was 11.1% and 50% in patients who underwent conservative and surgical treatment, respectively. Patients with other complications and patients with EJF had worse survival compared to patients without any complication (p = 0.004 and p = 0.013, respectively). Completion gastrectomy is the main risk factor for EJF occurrence. Still, EJF is associated with high postoperative mortality, longer hospital stay and has a negative impact on long-term survival.

Abstract
BACKGROUND Anastomotic failure after gastroenterological surgery is usually treated by intraperitoneal drainage and a mature ductal fistula. A ductal fistula may develop into a labial fistula. Although a ductal fistula is controllable, a labial fistula is intractable. We report a case of a labial fistula that communicated with the duodenal stump after gastrectomy. This condition was successfully treated by intraluminal drainage with continuous suction (IDCS) via a rectus abdominis musculocutaneous flap (RAMF). CASE REPORT A 70-year-old male underwent distal gastrectomy with intentional lymphadenectomy because of advanced gastric cancer. Digestive reconstruction was completed by the Billroth II method. Pancreatic leakage, intraperitoneal abscess, and anastomotic failure of gastrojejunostomy occurred after surgery. The duodenal stump was ruptured at postoperative day (POD) 26, and ductal fistula associated with the duodenum was observed. Unfortunately, this ductal fistula developed into a labial fistula at POD 90, and a high output of duodenal juice was observed. Additional surgery was proposed at POD 161. The broken stump and labial fistula were covered by a pedunculated RAMF, and a dual drainage system (a combination of a Penrose drain and a 2-way tube) travelled through the RAMF. The tip position of the drainage system was located in the duodenum, and the IDCS was effectively introduced. The secondary ductal fistula finally matured through the RAMF, and was subsequently closed at POD 231. The intractable labial fistula was successfully treated, and the patient was discharged at POD 235. CONCLUSIONS A high-output labial fistula, which communicated with the duodenal stump after gastrectomy, was refractory in our patient. Effective IDCS through an RAMF was useful for replacement of the labial fistula with a secondary ductal fistula.

Abstract
Anastomotic leakage (AL) is one of the most critical and detrimental complications in esophageal surgery. Early diagnosis and timely therapeutic action are necessary if patients are to avoid AL-related problems. However, there is no gold standard or consensus for early diagnosis. In this review, we focus on summarizing the definition and types of AL and modalities for early diagnosis of AL after esophagectomy.

Abstract
BACKGROUND Intestinal anastomotic insufficiency (AI) is a common problem in visceral surgery associated with overexpression of matrix metalloproteinases (MMPs). In some patients it occurs more than once. The etiology of recurring anastomotic insufficiency (RAI) is not understood yet and should be addressed as an independent disease entity. MATERIALS AND METHODS Thirty nine consecutive patients with AI were treated at our university center and were included in this prospective study. Clinical data were evaluated by correlative statistical analysis to identify independent risk factors for RAI. Patients were divided in two groups: 18 patients had a single operative revision until restoration (group SAI), and 21 patients had two or more revisions (group RAI). Anastomotic tissue samples as well as untouched bowel wall were collected during reoperations for analysis of MMPs and tissue inhibitor of metalloproteinases (TIMP2). Clinical data were correlated with pathological observations. RESULTS Significant differences of clinical and molecular pathological data were found between the two groups. Transfusion of red blood cells until the first reoperation and alcohol abuse led to RAI and were the only independent risk factors for RAI in multivariate analysis. Overexpression of MMP-8, -9, and -13 in anastomotic tissue correlated with the administration of red blood cells during initial operation. Reduced expression of TIMP2 was frequent in nearly all patients without differences throughout the subgroups. CONCLUSIONS RAI seems to have an independent disease pattern. Transfusion of blood products is not only a known risk factor for AI but seems to significantly disturb the anastomotic healing process leading to RAI.

Esophagojejunal anastomotic leakage following gastrectomy for gastric cancer. Surg Today 2018; 49:187-196. [PMID: 30317492 DOI: 10.1007/s00595-018-1726-8] [Citation(s) in RCA: 54] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2018] [Accepted: 09/27/2018] [Indexed: 02/07/2023]
Abstract
Esophagojejunal anastomotic leakage (EJAL) is a serious complication of total or proximal gastrectomy for gastric cancer, with a reported incidence of 2.1-14.6% and mortality of up to 50%. EJAL is an independent prognostic factor for the poor survival of gastric cancer patients. Meticulous surgical techniques, experience with anastomotic devices, and a thorough understanding of various risk factors and preventive measures are essential and early diagnosis is critical for preventing EJAL-related death. Patients with suspected EJAL must be evaluated promptly, but contrast swallow is not recommended. There is no standard treatment strategy for EJAL, although conservative treatment with drainage and nutritional support is the most common approach. Effective endoscopic treatments have been reported but need further validation. Surgical treatment is associated with high mortality but should be considered to prevent death from suboptimal EJAL management, for patients with severe sepsis or when conservative treatment has failed.

Safety and feasibility of laparoscopic reoperation for treatment of anastomotic leakage after laparoscopic colorectal cancer surgery. Asian J Endosc Surg 2018; 11:227-232. [PMID: 29322627 DOI: 10.1111/ases.12452] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Revised: 11/10/2017] [Accepted: 11/26/2017] [Indexed: 12/19/2022]
Abstract
INTRODUCTION The safety and feasibility of laparoscopic reoperation for anastomotic leakage remain unclear. METHODS A total of 3321 patients underwent laparoscopic surgery for primary colorectal cancer at a tertiary referral center from September 2002 to May 2016. Of these, 31 patients who underwent reoperation for treatment of anastomotic leakage were enrolled in this study and divided into two reoperation groups: laparoscopic (n = 15) and open (n = 16). Data regarding patient demographics, operative outcomes, morbidity, length of hospital stay, mortality, and stoma closure after reoperation in the two groups were compared. RESULTS No significant difference was observed in the primary surgery procedure between the two groups. Estimated blood loss (1 vs 9 mL, P = 0.020), total postoperative complications (26.7% vs 68.8%, P = 0.032), wound infection (0.0% vs 31.2%, P = 0.043), and postoperative hospital stay (18 vs 31 days, P = 0.017) were significantly better in the laparoscopic group than in the open group. Although the rate of stoma closure after reoperation was higher in the laparoscopic group, the difference was not significant (86.7% vs 62.5%, P = 0.220). CONCLUSIONS Laparoscopic reoperation exhibited better short-term outcomes than open reoperation for selected patients with anastomotic leakage.

Assessment of MMP-2/-9 expression by fluorescence endoscopy for evaluation of anastomotic healing in a murine model of anastomotic leakage. PLoS One 2018; 13:e0194249. [PMID: 29566031 PMCID: PMC5863981 DOI: 10.1371/journal.pone.0194249] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2017] [Accepted: 02/27/2018] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Disturbance of intestinal wound closure leads to insufficient anastomotic healing and is associated with considerable morbidity following colorectal resections. Matrix metalloproteinases (MMPs) play a crucial role in regulation of wound closure. Here fluorescence endoscopy was evaluated for assessment of MMP-2/-9 expression during failed intestinal anastomotic healing. METHODS Distal colonic anastomoses were performed as a model for disturbed healing in 36 Balb/c mice. Healing was evaluated endoscopically, macroscopically, and histologically after 1, 3 and 5 days. For detection of MMP-2/-9 expression fluorescence endoscopy (FE) was used following i.v.-administration of a Cy5.5-labeled MMP-2/-9 specific tracer. FE was complemented by quantification of the fluorescence signal using the MS-FX PRO Optical Imaging System. An overall leakage score was calculated and correlated with the results of FE. RESULTS With increasing incidence of anastomotic leakage from POD1 (17%) to POD5 (83%) the uptake of the MMP tracer gradually increased (signal-to-noise ratio (SNR), POD1: 17.91 ± 1.251 vs. POD3: 30.56 ± 3.03 vs. POD5: 44.8 ± 4.473, P<0.0001). Mice with defective anastomotic healing showed significantly higher uptake compared to non-defective (SNR: 37.37± 3.63 vs. 26.16± 3.635, P = 0.0369). White light endoscopy and FE allowed evaluation of anastomotic healing and visualization of mucosal MMPs in vivo. Using FE based detection of MMPs in the anastomosis, an overall positive predictive value of 71.4% and negative predictive value of 66.6% was calculated for detection of anastomotic leakage. CONCLUSION During disturbed anastomotic healing increased expression of MMP-2/-9 was observed in the anastomotic tissue. Fluorescence endoscopy for detection of MMP-2/-9 during the healing process might be a promising tool for early identification of anastomotic leakage.

Abstract
BACKGROUND Locoregional recurrence rates after definitive chemoradiotherapy (dCRT) for locally advanced esophageal cancer (EC) are high. Salvage surgery (SALV) is considered the best treatment option in case of persistent or recurrent disease for operable patients, but SALV has been associated with increased morbidity and mortality. The aim of this study is to identify factors linked to outcomes after SALV to better select candidates and to optimize perioperative care. STUDY DESIGN We retrospectively analyzed data from 308 consecutive SALV patients from a large multicenter European cohort. Univariate and multivariate analyses were performed to identify factors associated with in-hospital postoperative morbidity, anastomotic leakage (AL), and overall survival (OS). RESULTS The in-hospital postoperative mortality and morbidity rates were 8.4 and 34.7%, respectively. Squamous cell histology (p = 0.040) and radiation dose ≥ 55 Gy (p = 0.047) were independently associated with major morbidity. The AL rate was 12.7%, and cervical anastomosis was independently associated with AL (p = 0.002). OS at 5 years was 34.0%. Radiation dose ≥ 55 Gy (p = 0.003), occurrence of postoperative complications (p = 0.006), ypTNM stage 3 (p = 0.019), and positive surgical margins (p < 0.001) were linked to poor prognosis. CONCLUSIONS SALV is a valuable option for patients with persistent or recurrent disease after dCRT and offers long-term survival. Factors such as radiation dose and anastomosis location identified here will help to optimize outcomes after SALV, which may be considered a standard treatment in the EC therapeutic armamentarium.

Intracavitary Contrast-Enhanced Ultrasound in the Management of Post-Surgical Gastrointestinal Fistulas. ULTRASOUND IN MEDICINE & BIOLOGY 2018; 44:502-507. [PMID: 29229267 DOI: 10.1016/j.ultrasmedbio.2017.10.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2017] [Revised: 10/09/2017] [Accepted: 10/24/2017] [Indexed: 06/07/2023]
Abstract
The goal of this study was to investigate intracavitary contrast-enhanced ultrasound (IC-CEUS) measures in the management of post-surgical gastrointestinal (GI) fistula throughout detection, treatment and follow-up. From June 2010 to August 2016, patients who were administered ultrasound contrast agent (UCA) via a drainage tube for IC-CEUS were enrolled and retrospectively analyzed. They were suspected of having GI anastomotic fistulas or had been found to have fluid collections with ultrasound that were accompanied by abdominal pain or fever after surgical procedures. Forty-two patients met the inclusion criteria and were enrolled into this study. Twenty-two were confirmed to have GI fistulas confirmed by standard references. None were detected by conventional ultrasound. Although IC-CEUS successfully detected GI fistulas in 16 patients, it missed GI fistulas in 6 patients. One patient was misdiagnosed with a GI fistula. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the diagnosis of GI fistulas by IC-CEUS were 72.7% (16/22), 95.0% (19/20), 94.1% (16/17), 76.0% (19/25) and 83.3% (35/42), respectively. Twenty peritoneal fluid collections in 14 patients were related to fistulas by IC-CEUS based on the distribution of ultrasound contrast agents. Additional drainage was performed in 14 fistula-related fluid collections. Eight GI fistulas were judged to be cured after IC-CEUS re-evaluation, and the drainage tubes were removed from these patients. In conclusion, IC-CEUS can greatly improve the ability to diagnose post-surgical GI fistulas and may also play an important role in interventional treatment and follow-up.

Abstract
Objective Spontaneous esophageal rupture (SER) is a rare but life-threatening condition with high mortality. The prognosis of patients with SER treated with surgical intervention or the traditional “three-tube” method is controversial. Thus, the aim of this study was to evaluate the clinical efficacy, feasibility, and safety of a new “two-tube” method involving a trans-fistula drainage tube and a three-lumen jejunal feeding tube for the treatment of SER without concomitant pleural rupture. Methods From January 2007 to June 2016, patients with SER and managed with the “two-tube” method or other methods were retrospectively analyzed. Data collected included initial presentation, procedure time, duration of treatment, numbers of patients with eventual healing of leaks, and complications. Results The average procedure time for the “two-tube” method was 22.1 ± 5.5 minutes. In comparison with the control method, the “two-tube” method had a similar diagnosis time (3.6 ± 1.4 vs. 3.4 ± 1.4 days) but a significantly higher successful closure rate (94.4% vs. 63.6%) and shorter treatment time (38.2 ± 5.6 vs. 53.6 ± 16.9 days). No complications associated with performance of the “two-tube” method occurred. Conclusion The “two-tube” method is an effective and safe approach for patients with SER.

How do surgical stress and low perioperative serum protein and albumin impact upon short term morbidity and mortality in gastric cancer surgery? ACTA ACUST UNITED AC 2017; 90:71-85. [PMID: 28246501 PMCID: PMC5305092 DOI: 10.15386/cjmed-674] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Accepted: 05/05/2016] [Indexed: 12/29/2022]
Abstract
Background Patients undergoing surgery for gastric cancer may be expected to develop a certain range of postoperative complications. This retrospective cohort study determined if gauging the serum value of total proteins and albumins before and especially after surgery can predict an undesired short term outcome in patients with gastric resections for cancer, as we have not found studies debating the link between low postoperative total proteins or albumins and early postoperative morbidity. Methods A total of 195 patients with gastric cancer who had been subjected to gastric resection (83 patients) or total gastrectomy (111 patients), were subsequently arranged into study group pairs. In each of these group pairs, one group had a complication, while another was without said complication, or total vs. subtotal gastrectomy, etc. Each of these group pairs were compared between them in order to determine if total serum proteins and/or albumins, before and/or after surgery could predict the onset of certain complications or death. In the end, we performed ROC curves to determine the predictability value of variables for certain complications. Results preoperative serum albumin can predict an early onset of anastomotic leakage (p=0.02) as it can predict the occurrence of general complications (p=0.018) and surgical wound infections (p=0.029) as well as a higher risk of reoperation for the management of complications (p=0.028). Total serum protein may be tied to a higher surgical stress, like albumin, as it was significantly lower in patients undergoing total gastrectomy as compared to those subjected to subtotal gastrectomy (p=0.0001 total proteins, p=0.0001 albumins). Postoperative low total serum proteins and albumins translate in a risk of early postoperative death (p=0.031 total proteins, p=0.001 albumins). Conclusion We demonstrated the fact that total serum proteins and serum albumins, checked both before and after surgery, are of great value in helping predict a series of postoperative complications in gastric cancer surgery and that they can also be used as surgical stress markers.

New approaches in esophageal carcinomas. Innov Surg Sci 2016; 1:87-95.

Abstract
New approaches in the treatment of esophageal cancer comprise endoscopy with refinements of esophagoscopic intraluminal resection by endoscopic submucosal dissection. Radical open surgery is more and more replaced by minimally invasive esophagectomy (MIO), especially in the hybrid technique with laparoscopic gastrolysis and transthoracic esophageal resection and gastric pull-up. Total MIO also in the robotic technique has not yet shown that it produces superior results than the hybrid technique. Fluorescent dye can improve the intraoperative visualization of the vascularization of the gastric conduit. The individualization of neoadjuvant therapy is the magic word in clinical research of multimodal treatment of esophageal cancer. This means response prediction based on molecular markers or clinical response evaluation. The documentation of the diversity of postoperative complications is now standardized by an international consensus. The value of enhanced recovery after surgery is not yet approved compared to conventional management.

Abstract
With advances in abdominal surgery and the management of major trauma, complex abdominal wall defects have become the new surgical disease, and the need for abdominal wall reconstruction has increased dramatically. Subsequently, how to reconstruct these large defects has become a new surgical question. While most surgeons use native abdominal wall whenever possible, evidence suggests that synthetic or biologic mesh needs to be added to large ventral hernia repairs. One particular group of patients who exemplify "complex" are those with contaminated wounds, enterocutaneous fistulas, enteroatmospheric fistulas, and/or stoma(s), where synthetic mesh is to be avoided if at all possible. Most recently, biologic mesh has become the new standard in high-risk patients with contaminated and dirty-infected wounds. While biologic mesh is the most common tissue engineered used in this field of surgery, level I evidence is needed on its indication and long-term outcomes. Various techniques for reconstructing the abdominal wall have been described, however the long-term outcomes for most of these studies, are rarely reported. In this article, I outline current practical approaches to perioperative management and definitive abdominal reconstruction in patients with complex abdominal wall defects, with or without fistulas, as well as those who have lost abdominal domain.

Abstract
INTRODUCTION Enhanced recovery after surgery program (ERP) has now surpassed the stage of clinical research in certain specialties and currently poses the problematic of large-scale implementation. The goal of this study was to report the experience during the first year of implementation in three French-speaking countries. MATERIAL AND METHODS This is a prospective study in which 67 healthcare centers, all registered in the Grace-Audit databank, participated. Included were patients undergoing colorectal (CRS), bariatric (BS) and orthopedic hip and knee surgery (OS), performed within an ERP. The main endpoints were duration of hospital stay, postoperative morbidity, the degree of compliance with the elements of the ERP, the relation between the extent of application of the elements and postoperative hospital stay, and finally the completeness of data inclusions in the databank. RESULTS A total of 1904 patients were included in the Grace-Audit databank between January 1, 2015 and January 31, 2016, undergoing CRS (n=490), BS (n=431), and OS (n=983). The mean implementation rate was 83.7±10.0% for CRS, 75.0±23.7% for BS, and 83.5±14.9% for OS. The duration of hospital stay was 6.5 days for CRS, 2.6 days for BS and 3.4 days for OS. Overall postoperative morbidity (onset of postoperative undesirable event), surgical morbidity (superficial or deep organ space surgical site complications such as bleeding, infection or defective healing) and readmission rates were 20.6%, 7.5%, and 5.7% for CRS; 2.5%, 1.4%, and 1.6% for BS and 2.9%, 0.2%, and 2% for OS, respectively. A statistically significant relationship was found between the degree of compliance of the elements of ERP and the duration of hospital stay for CRS and BS; hospital stay was reduced when at least 15 of the 22 elements of the program were applied (P<0.001). The patients included in the Grace-Audit databank represented less than 20% of the patients undergoing operation in the same establishments during the study period for all three specialties. CONCLUSIONS This study shows that large-scale ERPs are feasible and safe in French-speaking countries. Nonetheless, although encouraging, these preliminary results highlight that implementation must be improved in specialties such as bariatric surgery and that more complete data collection is needed.

Abstract
BACKGROUND Inflammatory biomarkers usually start to rise earlier before the infection becomes clinically evident. This study was designed to evaluate the predictive performance of procalcitonin (PCT), C-reactive protein (CRP), and white blood cell (WBC) counts in postoperative intraabdominal infections (IAIs) after definitive operation of intestinal fistulae. MATERIAL AND METHODS We prospectively enrolled a total of 356 consecutive patients who underwent elective digestive tract reconstruction for gastrointestinal fistulae without existing clinical infection. Plasma PCT levels, serum CRP concentration, and WBC counts were assessed preoperatively and on postoperative days (PODs) 1, 3, 5, and 7. The predictive value of each laboratory marker for IAIs was calculated. RESULTS The occurrence rate of IAIs after elective digestive tract reconstruction for gastrointestinal fistulae in our study was 7.3%. Both PCT levels and WBC counts were significantly higher in patients with IAIs than those in patients without IAIs on POD 1, POD 3, and POD 5, whereas CRP levels differed significantly on POD 3 and POD 5. Receiver-operating characteristics demonstrated that PCT on POD 3 had the highest diagnostic accuracy for IAIs, and the area under the curve reached 0.86, with a sensitivity of 92.0% and specificity of 74.0%. CONCLUSIONS The value of PCT above 0.98 ng/L on POD 3 and 0.83 ng/L on POD 5 could predict the occurrence of IAIs after definitive operations for intestinal fistulae.

Abstract
BACKGROUND Previous studies investigated the efficacy and applicability of tissue adhesives in gastrointestinal surgery while no evidence is available to date about a novel compound, TachoSil (Takeda, Zurich, Switzerland). The primary aim of this observational study was to assess the effect of new fibrin sealant on the incidence of postoperative complications in a homogeneous group of patients submitted to upper gastrointestinal surgery for cancer. METHODS Two cohorts of 28 and 34 patients undergoing upper gastrointestinal for surgery were compared. In the first cohort, the anastomotic site was treated with TachoSil fibrinogen-thrombin-collagen patches and in the second no collagen sponge or any other hemostatic sealant was used. Postoperative complications and outcomes as well as postoperative biochemical parameters were analyzed. RESULTS Postoperative complications occurred in 12 patients (35.3%) and 2 patients (7.1%) in control and collagen sponge group respectively (χ2 = 3.539, p < 0.05), with no anastomotic leakage in the collagen sponge group. A binary logistic regression analysis showed that the nonuse of collagen sponge [odds ratio (OR) = 0.025, 95% confidence interval (CI) = 0.001-0.457, p = 0.01] was independently associated with postoperative complication occurrence. CONCLUSIONS The addition of fibrinogen-thrombin-collagen sponge patch may reduce postoperative complication rate after upper gastrointestinal surgery for cancer. Further study to delineate the role of TachoSil in gastrointestinal surgery are also needed to demonstrate improved effectiveness and applicability.
