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