Resected Gastric Volume / Number of Staplers Fired Ratio as a Tool in Predicting Complication and Midterm Results in Sleeve Gastrectomy

Abstract Background Laparoscopic sleeve gastrectomy is a restrictive surgery that aims to decrease the patients’ gastric volume. This study hypothesized that increased resected gastric volume/number of staplers fired ratio is associated with better postoperative 12th -month outcomes. Objectives To analyze the effects of resected gastric volume/number of staplers fired ratio on postoperative results of patients with sleeve gastrectomy. Setting: University Hospital, Istanbul, Türkiye Methods We analyzed the data of 407 patients who underwent laparoscopic sleeve gastrectomy between 2018–2022. The primary outcome was the effect of resected gastric volume/number ratio on postoperative 12th -month excess weight loss. Results A total of 407 patients were included in the study. The higher resected gastric volume/number of staplers fired ratio was associated with higher excess weight loss in the postoperative 12th -month, and no effect was found in complications (p = 0.001 and p = 0.785, respectively). Conclusion This study revealed that resected gastric volume/number of staplers fired could be used to predict weight loss. Further studies should inspect the effect of resected gastric volume/number of staplers fired on complications.
