Analysis of Factors Affecting the Occurrence of Gallbladder Stones After Laparoscopic Sleeve Gastrectomy: A Single-Center Retrospective Study
Journal Title: Journal of Surgery Research and Practice - Year 2025, Vol 6, Issue 1
Abstract
Background: Postoperative gallstone formation is a significant complication following Laparoscopic Sleeve Gastrectomy (LSG). However, the risk factors and prevention strategies are not yet fully understood. This study aimed to investigate the risk factors for gallstone formation after LSG and provide insights into their prevention and management. Methods: A single-center retrospective study was conducted on patients who underwent LSG at our hospital between June 2015 and June 2023. The study included patients diagnosed with obesity and met the indications for LSG. Data on patient characteristics, surgical procedures and postoperative follow-up were collected and analyzed using SPSS26.0. Binary logistic regression was utilized to evaluate the impact of various factors on the occurrence of gallstones after LSG. Results: A total of 172 patient records were collected for this study. After excluding patients with preoperative gallbladder stones, those who underwent cholecystectomy and those who did not complete regular follow-ups, a final sample of 140 patients was included. The average age was 31.59±7.94 years, with a mean preoperative weight of 110.84±24.41 kg and a mean preoperative BMI of 39.58±7.37 kg/m². The average operation time was 74.6±20.0 minutes and the average hospital stay was 7.1±2.9 days. Binary logistic regression analysis revealed that Excess Weight loss at 6 months (EWL6) was a risk factor for post-LSG gallstone formation (P<0.05), while age, gender, BMI, EWL12, TWL6, TWL12，hypertension, diabetes, degree of hepatic steatosis, presence of duodenal ulcer inflammation and presence of gastritis were not identified as risk factors for gallstone formation after LSG (P>0.05). Conclusion: This study identified excess weight loss at 6 months as a significant risk factor for gallstone formation after LSG. Further research is needed to explore the underlying mechanisms and develop effective prevention and management strategies for postoperative gallstone formation in patients undergoing LSG.
