Core Tip
Core Tip: This study investigated the effect of resected gastric volume on weight loss after sleeve gastrectomy. The findings revealed that although resected gastric volume correlated with preoperative body weight, it did not predict postoperative weight loss, supporting the concept that weight reduction after sleeve gastrectomy is influenced by multifactorial mechanisms beyond gastric volume alone.
