Abstract
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a commonly performed type of bariatric surgery. Early complications of LSG include bleeding, leakage, pulmonary embolism, and surgical site infections. Most surgeons try to implement preventive methods, such as omentopexy. Staple line-imbrication, which has a difficult learning curve, often prevents complications. This study aimed to evaluate the effect of omentopexy on patients with imbricated LSG. MATERIAL AND METHODS: The study applied a retrospective data analysis design to patients who underwent LSG between 2020 and 2023. All patients' staple lines were imbricated, and patients were then divided into two groups: omentopexy group and control group. Patients' demographic features, such as age, gender, height, weight, body mass index(BMI), bleeding, leakage, and reoperations, were recorded and examined retrospectively. RESULTS: A total of 1356 patients were included in the study (540 in omentopexy, 816 in control), of which the mean age was 37.9 ± 10.5 years, 82.3% were women, and mean BMI was 40.9 ± 5.8 kg/m(2). The mean bleeding rate was 1.0% (1.3-0.7%), the mean leakage rate was 0.2% (0.2-0.2%, respectively), and the mean reoperation rate was 0.6% (0.7% and 0.5%, respectively). No statistically significant differences were observed. CONCLUSION: Omentopexy is a technique that is widely used to prevent staple line complications. According to our study, omentopexy applied to an imbricated stapler line increased the operation time but did not affect bleeding or leakage ratios. This is the first study to evaluate the effect of omentopexy on imbricated staple lines. The findings of the study indicate that omentopexy has no additional benefit on early complications when using staple-line imbrication.
