Abstract
Background: It has been reported that Laparoscopic sleeve gastrectomy duration was associated with increased risk of the perioperative and postoperative complications. This study investigates the risk factors associated with long duration of the surgery, thus the risk for the perioperative and postoperative complications. Methods: A retrospective Cohort study was conducted. Pearson correlation and Wilcoxon rank test were used as to detect the relationship between continuous and categorical variables, respectively. A multivariate regression analysis was used to detect the possible predictors of the long operative time. Results: The age, sex, co-morbidities and laboratory tests did not affect the duration of the LSG. Meanwhile, the concomitant cholecystectomy (P-value = 0.08) and gall stones (P-value = 0.015) were the main determinant of the operative time, however, both failed to predict the duration of LSG (P-value > 0.05). Conclusion: The study suggests that the main determinant of long duration of the LSG are the intraoperative concomitant surgeries and the technique of the surgery.
