Single Layer Interrupted Gastroenterostomy, A Superior Technique Over Double Layer Continuous Gastroenterostomy

Background: Gastroenterostomy is a widely performed surgical procedure for treating gastric outlet obstruction and other upper gastrointestinal pathologies. Traditionally, the double-layer continuous technique has been the standard due to its perceived durability. However, it is associated with increased operative time, tissue handling, and risk of postoperative complications such as anastomotic leakage. In recent years, the single-layer interrupted technique has emerged as a potentially superior method, offering advantages in terms of operative simplicity, reduced tissue trauma, and faster recovery. Objective: This study aimed to compare the clinical outcomes of single-layer interrupted gastroenterostomy with the conventional double-layer continuous method, focusing on operative time, postoperative complications, recovery period, and overall effectiveness. Method: A prospective randomized study was conducted between January 2023 and December 2024 at the Department of Surgery, Rangpur Medical College Hospital, Bangladesh. A total of 100 patients requiring gastroenterostomy were randomly assigned into two groups: Group A (n=50) underwent single-layer interrupted anastomosis, while Group B (n=50) underwent double-layer continuous anastomosis. Key outcomes measured included operative convenience, operative time, intraoperative blood loss, postoperative complications (e.g., leak, infection), time to return of bowel function, and hospital stay duration. Result: Group A demonstrated significantly shorter operative times (average 90 minutes vs. 120 minutes), less blood loss, and earlier return to oral feeding. Postoperative complication rates, including wound infection and anastomotic leak, were lower in the single-layer group. Mean hospital stay was also shorter in Group A (5 days vs. 7 days), indicating a faster recovery profile. Conclusion: The single-layer interrupted gastroenterostomy technique offers a simpler, easier, safer, and more efficient alternative to the tra
