The effect of staple line reinforcement on complication rates in patients undergoing sleeve gastrectomy

The Effect of Staple Line Reinforcement on Complication Rates in Patients Undergoing Sleeve Gastrectomy Abstract Aim: Although many findings have been made regarding surgical technique in sleeve gastrectomy, staple line reinforcement remains controversial. In our study, we aimed to discuss the effect of staple line reinforcement on complication rates. Methods: Patients who underwent sleeve gastrectomy for obesity treatment at our clinic between January 2013 and June 2025 were identified through the hospital's electronic data system. Patients over the age of 18, those who did not undergo staple line reinforcement, those who underwent staple line reinforcement involving the omentum, and those with no missing data were included in the study. Patient demographics, as well as BMI, comorbidities, staple line reinforcement techniques, and surgical complications, were recorded. Results: 191 patients underwent sleeve gastrectomy between the specified dates. Of these patients, 138 were female and 53 were male. The patients' mean BMI was 44.77 8.01 kilograms. There were 75 patients with comorbidities. The number of patients in whom we reinforced the staple line was 56. A total of 6 patients developed complications. All patients who developed complications were in the group without staple line reinforcement. There were no mortality rates. Conclusion: Staple line reinforcement after sleeve gastrectomy is an effective method for reducing complication rates. Keywords: Morbid obesity; Sleeve gastrectomy; Leak rate
