Comparative Study on the Efficacy of Single-Layer vs. Double-Layer Small Gut Anastomosis in Patients Admitted to a Tertiary Care Center

Abstract

Background: For a number of gastrointestinal diseases, small bowel resection with anastomosis is a common surgical treatment. The choice of anastomotic technique, specifically between single-layer and double-layer approaches, is still up for debate. Methods: Between December 2020 and June 2022, 50 patients who had small intestinal resections participated in this prospective observational study. Single-layer anastomosis (n = 28) and double-layer anastomosis (n = 22) groups of patients were created. Anastomotic leaks, postoperative complications, hospital stay, bowel function recovery, and patient satisfaction were all included in the outcome measures. Chi-squared and t-tests were utilized in the statistical analysis. Results: There was no statistically significant difference between the anastomotic leak rates of 7.1% in the single-layer group and 4.5% in the double-layer group (p > 0.05). Similar postoperative problems, hospital stays (averaged 6 days), recovery times for bowel function (averaged 3 days), and patient satisfaction levels were seen in both groups. Conclusion: Current study shows that single-layer and double-layer techniques yield equivalent results in small bowel resection and anastomosis. The fact that these procedures have similar anastomotic leaks, postoperative complications, hospital stays, and bowel function restoration times suggests that the surgeon's preference and experience may influence the decision. Both groups have great patient satisfaction, suggesting that the anastomotic approach has little to no impact on patient treatment.
