Small bowel anastomosis in emergency surgery.

BACKGROUND: Emergency laparotomy is associated with a high morbidity and mortality rate. The decision on whether to perform an anastomosis or an enterostomy in emergency small bowel resection is guided by surgeon preference alone, and not evidence based. We examined the risks involved in small bowel resection and anastomosis in emergency surgery. METHODS: A retrospective study from 2016 to 2019 in a university hospital in Denmark, including all emergency laparotomies, where small-bowel resections, ileocecal resections, right hemicolectomies and extended right hemicolectomies where performed. Demographics, operative data, anastomosis or enterostomy, as well as postoperative complications were recorded. Primary outcome was the rate of bowel anastomosis. Secondary outcomes were the anastomotic leak rate, mortality and complication rates. RESULTS: During the 3.5-year period, 370 patients underwent emergency bowel resection. Of these 313 (84.6%) received an anastomosis and 57 (15.4%) an enterostomy. The 30-day mortality rate was 12.7% (10.2% in patients with anastomosis and 26.3% in patients with enterostomy). The overall anastomotic leak rate was 1.6%, for small-bowel to colon 3.0% and for small-bowel to small-bowel 0.6%. CONCLUSION: A primary anastomosis is performed in more than eight out of 10 patients in emergency small bowel resections and is associated with a very low rate of anastomotic leak.

Understanding early deaths after major emergency abdominal surgery: An observational study of 754 patients.

BACKGROUND: Major emergency abdominal surgery is associated with severe postoperative complications and high short- and long-term mortality. Despite recent advancements in standardizing multidisciplinary care bundles, a subgroup of patients continues to face a heightened risk of short-term mortality. This study aimed to identify and describe the high-risk surgical patients and risk factors for short-term postoperative mortality. METHODS: In this study, we included all patients undergoing major emergency abdominal surgery over 2 years and collected data on demographics, intraoperative variables, and short-term outcomes. The primary outcome measure was short-term mortality and secondary outcome measures were pre, intra, and postoperative risk factors for premature death. Multivariable binary regression analysis was performed to determine possible risk factors for short-term mortality. RESULTS: Short-term mortality within 14 days of surgery in this cohort of 754 consecutive patients was 8%. Multivariable analysis identified various independent risk factors for short-term mortality throughout different phases of patient care. These factors included advanced age, preoperative history of myocardial infarction or ischemic heart disease, chronic obstructive pulmonary disease, liver cirrhosis, chronic kidney disease, and vascular bowel ischemia or perforation of the stomach or duodenum during the primary surgery. CONCLUSION: Patients at high risk of early mortality following major emergency abdominal surgery exhibited distinct perioperative risk factors. This study underscores the importance of clinicians identifying and managing these factors in high-risk patients to ensure optimal care.

Standardization of the strategy for open abdomen in nontrauma emergency laparotomy: A prospective study of outcomes in primary versus temporary abdominal closure.

BACKGROUND: The indications for temporary abdominal closure in nontrauma surgery are heterogeneous and with limited data on clinical outcomes. This study aimed to report the outcomes of primary closure compared with temporary abdominal closure after nontrauma emergency laparotomy within a standardized clinical setting adapted from international guidelines. METHODS: Included were all nontrauma patients undergoing emergency laparotomy between January 1, 2021, and December 31, 2022, at Copenhagen University Hospital Herlev in Denmark. All patients received treatment on the basis of standardized bundle of care trajectory for major emergency abdominal surgery. Mortality, risks of re-laparotomy, and postoperative complications were assessed using Kaplan-Meier plots and multiple logistic regression modeling. RESULTS: Of the 576 included patients, temporary abdominal closure was performed in 57 (10%) patients in the initial surgery. Indications for temporary abdominal closure included damage control strategy as the result of considerable hemodynamic instability in 21 (37%) patients, need for reassessment of bowel viability in 21 (37%) patients, and loss of domain in 15 (25%) patients. Fascial closure was achieved after a median period of 2 days. Sixty-seven patients (12%) underwent re-laparotomy, with temporary abdominal closure performed in 10 (15%) of the cases. Patients with temporary abdominal closure had a significantly greater risk of postoperative complications (odds ratio 2.58, 95% confidence interval 1.38-4.89, P = .003). There were no significant differences in the risks of fascial dehiscence, re-laparotomy, or 30- or 90-days mortality. CONCLUSION: Temporary abdominal closure was performed in 10% of patients undergoing nontrauma emergency laparotomy, with the primary indications being damage control strategy and need for reassessment of bowel viability. Patients undergoing temporary abdominal closure had a significantly greater risk of postoperative complications.
