Abstract
AIM Prolonged postoperative ileus (PPOI) is common and is associated with a significant healthcare burden. Previous studies have attempted to predict PPOI clinically using risk prediction algorithms. The aim of this work was to systematically review and compare risk prediction algorithms for PPOI following colorectal surgery. METHOD A systematic literature search was conducted using MEDLINE, Embase, Web of Science and CINAHL Plus. Studies that developed and/or validated a risk prediction algorithm for PPOI in adults following colorectal surgery were included. Data were collected on study design, population and operative characteristics, the definition of PPOI used and risk prediction algorithm design and performance. Quality appraisal was assessed using the PROBAST tool. RESULTS Eleven studies with 87 549 participants were included in our review. Most were retrospective, single-centre analyses (6/11, 55%) and rates of PPOI varied from 10% to 28%. The most commonly used variables were sex (8/11, 73%), age (6/11, 55%) and surgical approach (5/11, 45%). Area under the curve ranged from 0.68-0.78, and only three models were validated. However, there was significant variation in the definition of PPOI used. No study reported sensitivity, specificity or positive/negative predictive values. CONCLUSION Currently available risk prediction algorithms for PPOI appear to discriminate moderately well, although there is a lack of validation data. Future studies should aim to use a standardized definition of PPOI, comprehensively report model performance and validate their findings using internal and external methodologies.

Tracy BM, Srinivas S, Baselice H, Gelbard RB, Coleman JR. Surgical Apgar scores predict complications after emergency general surgery laparotomy. J Trauma Acute Care Surg 2024; 96:429-433. [PMID: 37936276 DOI: 10.1097/ta.0000000000004189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/09/2023]
Abstract
BACKGROUND The Surgical Apgar Score (SAS) is a 10-point validated score comprised of three intraoperative variables (blood loss, lowest heart rate, and lowest mean arterial pressure). Lower scores are worse and predict major postoperative complications. The SAS has not been applied in emergency general surgery (EGS) but may help guide postoperative disposition. We hypothesize that SAS can predict complications in EGS patients undergoing a laparotomy. METHODS We performed a retrospective review of adult patients at a single, quaternary care center who underwent an exploratory laparotomy for EGS conditions within 6 hours of surgical consultation from 2015 to 2019. Patients were grouped by whether they experienced a postoperative complication (systemic, surgical, and/or death). Multivariable regression was performed to predict complications, accounting for SAS and other statistically significant variables between groups. Using this model, predicted probabilities of a complication were generated for each SAS. RESULTS The cohort comprised 482 patients: 32.8% (n = 158) experienced a complication, while 67.2% (n = 324) did not. Patients with complications were older, frailer, more often male, had worse SAS (6 vs. 7, p < 0.0001) and American Society of Anesthesiologists scores, and higher rates of perforated hollow viscus ( p = 0.0003) and open abdomens ( p < 0.0001). On multivariable regression, an increasing SAS independently predicted less complications (adjusted odds ratio, 0.85; 95% confidence interval, 0.75-0.96; p = 0.009). An SAS ≤4 was associated with a 49.2% predicted chance of complications, greater rates of septic shock (9.7% vs. 3%, p = 0.01), respiratory failure (20.5% vs. 10.8%, p = 0.02), and death (24.1% vs. 7.5%, p < 0.0001). An SAS ≤ 4 did not correlate with surgical complications ( p = 0.1). CONCLUSION The SAS accurately predicts postoperative complications in EGS patients undergoing urgent laparotomy, with an SAS ≤ 4 identifying patients at risk for septic shock, respiratory failure, and mortality. This tool can aid in rapidly determining postoperative disposition and resource allocation. LEVEL OF EVIDENCE Therapeutic/Care Management; Level IV.

Abstract
BACKGROUND Incidence of, and potential risk factors for, postoperative gastrointestinal dysfunction (POGD) after gastrointestinal procedures performed in US hospitals were examined. METHODS This retrospective study used hospital discharge data of inpatients who underwent ≥1 gastrointestinal procedures from 1-Jan-2016 to 30-Apr-2019. POGD incidence was calculated based on all hospitalizations for MDC-06 procedures. Predictors of POGD were assessed using multivariable logistic regression. RESULTS POGD incidence was 5.8% among 638 611 inpatient hospitalizations. Major bowel procedures, peritoneal adhesiolysis, and appendectomy were the most notable predictors of POGD among gastrointestinal procedures assessed (adjusted odds ratios [95% confidence intervals]: 2.71 [2.59-2.83], 2.48 [2.34-2.64], and 2.15 [2.03-2.27], respectively; all p < 0.05). Procedures performed by colorectal/gastroenterology specialists (0.86 [0.84-0.89]), and those performed percutaneously (0.55 [0.54-0.56]) were associated with significantly lower odds of POGD (both P < 0.05). CONCLUSIONS Findings may help clinicians tailor management plans targeting patients at high-risk of POGD.

Abstract
Abdominal adhesion occurs commonly in clinical practice, causing unfavorable symptoms and readmission. The ileostomy operation is a common surgical procedure and we utilized this model to evaluate abdominal adhesion. Adhesion grade score was calculated in 35 patients (Cohort 1) and subjected to correlation and receiver operating characteristic analysis. Then 98 consecutive patients (Cohort 2) who underwent ileostomy and ileostomy closure were included into a retrospective study. Logistic regression analysis was performed, and the risk of small bowel obstruction was also assessed. The time of ileostomy closure correlated with adhesion grade score in Cohort 1, justifying its use as an indicator of abdominal adhesion. All patients in Cohort 2 were then divided into the high- and low-adhesion group. A multi-variable logistic regression analysis indicated that type of surgery and peritoneum suture during ileostomy were significant factors affecting the risk of abdominal adhesion. Abdominal adhesion had the trend to prolong the length of stay postoperatively without increasing the risk of bowel obstruction. Nine patients suffered bowel obstruction, and age older than 65 significantly increased the risk. We proposed the ileostomy procedure to be a model of abdominal adhesion, and the operative time of ileostomy closure could be used as an alternative of adhesion score. Type of surgery and peritoneum suture may be risk factors of abdominal adhesion. Older age increased the risk of small bowel obstruction after ileostomy surgery.

Abstract
OBJECTIVE Postoperative ileus (POI) is a relatively common complication after spinal fusion surgery, which can lead to delayed recovery, prolonged length of stay and increased medical costs. However, little is known about the incidence and risk factors of POI after corrective surgery for patients with adolescent idiopathic scoliosis (AIS). This study was performed to report the incidence of POI and identify the independent risk factors for POI after postoperative corrective surgery. METHODS In this retrospective cohort study, A total of 318 patients with AIS who underwent corrective surgery from April 2015 to February 2021 were enrolled and divided into two groups: those with POI and those without POI. The Student's t test, Mann-Whitney U test, and Pearson's chi-square test were used to compare the two groups regarding patient demographics and preoperative characteristics (age, sex and the major curve type), intraoperative and postoperative parameters (lowest instrumented vertebra [LIV], number of screws, and length of stay), radiographic parameters (T5-12 thoracic kyphosis [TK], T10-L2 thoracolumbar kyphosis and height [TLK and T10-L2 height], L1-S1 lumbar lordosis [LL], and L1-5 height). Then, a multivariate logistic regression analysis was used to identify independent risk factors for POI, and a receiver operating characteristic (ROC) curve was performed to assess the predictive values of these risk factors. RESULTS Forty-two (13.2%) of 318 patients who developed POI following corrective surgery were identified. The group with POI had a significantly longer length of stay, more lumbar screws, higher proportions of a major lumbar curve and lumbar anterior screw breech, and a lower LIV. Among radiographic parameters, the mean lumbar Cobb angle at baseline, the changes in the lumbar Cobb angle, and T10-L2 and L1-5 height from before to after surgery were significantly larger in the group with POI than in the group without POI. Multivariate logistic regression analysis showed that large changes in T10-L2 (odds ratio [OR] =2.846, P = 0.007) and L1-5 height (OR = 31.294, p = 0.000) and lumbar anterior screw breech (OR = 5.561, P = 0.006) were independent risk factors for POI. The cutoff values for the changes in T10-L2 and L1-5 height were 1.885 cm and 1.195 cm, respectively. CONCLUSION In this study, we identified that large changes in T10-L2 and L1-5 height and lumbar anterior screw breech were independent risk factors for POI after corrective surgery. Improving the accuracy of pedicle screw placement might reduce the incidence of POI, and greater attention should be given to patients who are likely to have large changes in T10-L2 and L1-5 height after corrective surgery.

Abstract
Aim This study aims to evaluate the incidence of postoperative ileus (POI) following cytoreductive surgery in epithelial ovarian cancer (EOC) patients and its impact on anastomotic leakage occurrence and postoperative complications. Methods A total of 357 surgeries were performed on 346 ovarian cancer patients between 1/2010 and 12/2020 at our institution. The postoperative course regarding paralytic ileus, anastomotic leakage, and postoperative complications was analyzed by Fisher's exact test and through ordinal logistic regression. Results A total of 233 patients (65.3%) returned to normal gastrointestinal functions within 3 days after surgery. A total of 123 patients (34.5%) developed POI. There were 199 anastomoses in 165 patients and 24 leakages (12.1%). Postoperative antibiotics (p 0.001), stoma creation (p 0.0001), and early start of laxatives (p 0.0048) significantly decreased POI, while anastomoses in general (p 0.0465) and especially low anastomoses (p 0.0143) showed increased POI rates. Intraoperative positive fluid excess >5,000 cc was associated with a higher risk for POI (p 0.0063), anastomotic leakage (p 0.0254), and severe complications (p 0.0012). Conclusion Postoperative antibiotics, an early start with laxatives, and stoma creation were associated with reduced POI rates. Patients with anastomoses showed an increased risk for POI. Severe complications, anastomotic leakages, and POI were more common in the case of intraoperative fluid balance exceeding 5,000 cc.

Abstract
Background Given the ever-shorter length of hospital stay after surgical procedures, nowadays it is more important than ever to study interventions that may have an impact on surgical patients’ wellbeing. According to the ERAS (Enhanced Recovery After Surgery protocols) program, early feeding must be considered one of the key components to facilitate early recovery while improving outcomes and patients’ overall experiences. To date, the international literature has reported that early postoperative feeding compared with traditional (or late) timing is safe; nevertheless, small clinical outcomes effects has been reported, also for recovery of gastrointestinal function. Therefore, the effectiveness of early postoperative feeding to reduce postoperative ileus duration remains still debated. Objective To analyse the effects of early versus delayed oral feeding (liquids and food) on the recovery of intestinal motility after gastrointestinal surgery. Search methods Pubmed, Embase, Cinahl, Cochrane Central Register of Controlled Trials (CENTRAL), and the ClincalTrials.gov register will be searched to identify the RCTs of interest. Study inclusion Randomized clinical trials (RCTs) comparing the effect of early postoperative versus late oral feeding on major postoperative outcomes after gastrointestinal surgery will be included. Data collection and analysis Two review authors will independently screen titles and abstracts to determine the initially selected studies’ inclusion. Any disagreements will be resolved through discussion and consulting a third review author. The research team members will then proceed with the methodological evaluation of the studies and their eligibility for inclusion in the systematic review.

Abstract
Objective Postoperative gastrointestinal dysfunction is a common and important complication of surgery. This study aimed to explore the key pharmacological mechanisms of Tongfu decoction in treating postoperative ileus (POI). Methods The active ingredients of Tongfu decoction and their targets were screened using the TCMSP database and STITCH and SwissTargetPrediction databases, respectively. The GeneCards and DisGeNET databases were used to obtain POI dysfunction-related therapeutic targets. After screening, a drug-active-ingredient-therapeutic target network was constructed and the key target functional enrichment analysis was carried out. The Sprague–Dawley rats with POI were used for in vivo experimental verification. The serum levels of IL-1β, IL-6, IL-10, IFN-γ, and MCP-1 were measured after surgery using enzyme-linked immunosorbent assay. The Western blot analysis was used to determine the expression of key proteins of the PI3K-Akt signaling pathway in colon tissues. Results An interaction network was constructed containing 7 Chinese medicine components, 36 compounds, and 85 target proteins. The functional enrichment analysis showed that the target proteins mainly acted on the POI through the PI3K-Akt signaling pathway. In in vivo experiments, Tongfu decoction had a promoting effect on the serum level of IL-10, an inhibitory effect on the serum levels of IL-1β and CCL2, and an inhibitory effect on the local expression of PI3K, pAkt, and mTOR in colon tissue. In addition, the Tongfu decoction increased the intestinal ink advancing rate. Conclusion Nonoral Tongfu decoction can also be used to treat POI; its mechanism is affected by IL-10 and IL-1β.The inhibition of the PI3K-Akt signaling pathway affected the treatment with Tongfu decoction by inducing an immune-inflammatory storm in POI.

Abstract
Postoperative ileus (POI) has long been a challenging clinical problem for both patients and healthcare physicians alike. Although a standardized definition does not exist, it generally includes symptoms of intolerance to diet, lack of passing stool, abdominal distension, or flatus. Not only does prolonged POI increase patient discomfort and morbidity, but it is possibly the single most important factor that results in prolongation of the length of hospital stay with a significant deleterious effect on healthcare costs in surgical patients. Determining the exact pathogenesis of POI is difficult to achieve; however, it can be conceptually divided into patient-related and operative factors, which can further be broadly classified as neurogenic, inflammatory, hormonal, and pharmacological mechanisms. Different strategies have been introduced aimed at improving the quality of perioperative care by reducing perioperative morbidity and length of stay, which include Enhanced Recovery After Surgery (ERAS) protocols, minimally invasive surgical approaches, and the use of specific pharmaceutical therapies. Recent studies have shown that the ERAS pathway and laparoscopic approach are generally effective in reducing patient morbidity with early return of gut function. Out of many studies on pharmacological agents over the recent years, alvimopan has shown the most promising results. However, due to its potential complications and cost, its clinical use is limited. Therefore, this article aimed to review the pathophysiology of POI and explore recent advances in treatment modalities and prevention of postoperative ileus.

Abstract
Background Postoperative ileus (POI) is associated with increased patient discomfort, length of stay (LOS), and healthcare cost. There is a paucity of literature examining POI in patients who have an ileostomy formed at the time of surgery. We aimed to identify risk factors for and outcomes associated with POI following ileostomy formation. Methods We included 261 consecutive non-emergent cases that included formation of an ileostomy by a board-certified colorectal surgeon at our institution from July 1, 2015, to June 30, 2020. Demographic, clinical, and intraoperative factors associated with increased odds of POI were evaluated. Post-procedure LOS, hospitalization cost, and re-admissions between patients with and without POI were compared. Results Out of 261 cases, 85 (32.6%) were associated with POI. Patients with POI had significantly higher body mass index (BMI) than those without POI (26.6 kg/m2 vs. 24.8kg/m2; p = 0.01). Intraoperatively, patients with POI had significantly longer procedure duration than those without POI (313 min vs. 279 min; p = 0.02). Patients with POI had a significantly higher net fluid balance at postoperative day (POD) 2 than those without POI (+ 2.65 L vs. + 1.80 L; p = 0.004), with POD2 fluid balance greater than + 807 mL (determined as the maximum Youden index for sensitivity over 80%) associated with a higher rate of POI (p = 0.006). This difference remained significant when adjusted for age, gender, BMI, pre-operative opioid use, procedure duration, and operative approach (p = 0.01). Patients with POI had significantly longer LOS (11.40 days vs. 5.12 days; p < 0.001) and direct cost of hospitalization ($38K vs. $22K; p < 0.001). Conclusions Minimizing fluid overload, particularly in the first 48 h after surgery, may be a strategy to reduce POI in patients undergoing ileostomy formation, and thus decrease postoperative LOS and hospitalization cost. Fluid restriction, diuresis, and changes in diet advancement or early stoma intubation should be considered measures that may improve outcomes and should be studied more intensively.

Abstract
Maximal cytoreductive surgery is an important prognostic factor in advanced epithelial ovarian cancer (EOC). To achieve maximal cytoreductive surgery, en bloc pelvic resection with rectosigmoid colectomy can be an effective surgical strategy. This surgical methodology was first described in 1968 as "radical oophorectomy." Since then, it has been adopted by many medical institutions around the world, and its safety has been shown by many studies. However, research on the surgical method is still lacking due to the limited number of prospective comparative studies. We will review the journals on en bloc pelvic resection with rectosigmoid colectomy published to date and discuss its efficacy, complications, and surgical techniques of the procedures.

Abstract
PURPOSE Postoperative Ileus (POI) remains an important complication for patients after abdominal surgery with an incidence of 10-27% representing an everyday issue for abdominal surgeons. It accounts for patients' discomfort, increased morbidity, prolonged hospital stays, and a high economic burden. This review outlines the current understanding of POI pathophysiology and focuses on preventive treatments that have proven to be effective or at least show promising effects. METHODS Pathophysiology and recommendations for POI treatment are summarized on the basis of a selective literature review. RESULTS While a lot of therapies have been researched over the past decades, many of them failed to prove successful in meta-analyses. To date, there is no evidence-based treatment once POI has manifested. In the era of enhanced recovery after surgery or fast track regimes, a few approaches show a beneficial effect in preventing POI: multimodal, opioid-sparing analgesia with placement of epidural catheters or transverse abdominis plane block; μ-opioid-receptor antagonists; and goal-directed fluid therapy and in general the use of minimally invasive surgery. CONCLUSION The results of different studies are often contradictory, as a concise definition of POI and reliable surrogate endpoints are still absent. These will be needed to advance POI research and provide clinicians with consistent data to improve the treatment strategies.
