A model to determine factors influencing intraoperative complications in sleeve gastrectomy.

Objective: The study presents a logistic regression model describing the factors leading to intraoperative complications in laparoscopic sleeve gastrectomy (LSG) and a detailed description of the intraoperative complications that occurred in our operations.

Material and methods: The study was designed as a retrospective and cohort study. It includes patients who underwent laparoscopic sleeve gastrectomy between January 2008 and December 2020.

Results: The study included 257 patients. The mean (SD) age of all patients included in the study was 40.28 (9.58) years. The body mass index of our patients ranged from 31.2 to 86.6 kg/m2. The Stepwise Backward model was used (Cox and Snell R2 = 0.051, Nagelkerke R2 = 0.072, Hosmer-Lemesxow χ2 = 1.968, df = 4, p = 0.742, overall model accuracy of 70.4%). The model shows that pre-operative diabetes mellitus or hypertension Stage 3 significantly increases the probability or risk of intraoperative complications.

Conclusions: The study shows which intraoperative complications occur in LSG, how they can be remedied and which factors can lead to them and influence the outcome of the operation itself. The recognition and successful treatment of intraoperative complications are very important as they reduce the number of reoperations and treatment costs.
