Analysis of risk factors for complications after laparoscopic cholecystectomy

Objective: To analyze the risk factors of complications after laparoscopic cholecystectomy in 478 patients in our hospital. Methods: The clinical data of 478 patients who underwent laparoscopic cholecystectomy in our hospital from March 2018 to September 2022 were collected, and the occurrence of postoperative complications and related risk factors were analyzed. Results: A total of 36 patients (7.53%) had complications, including 9 cases (1.88%) of abdominal hemorrhage, 8 cases (1.67%) of bile duct injury, and 19 cases (3.97%) of biliary fistula. Univariate analysis showed that adhesions of Calot triangle, anatomical variation and gallbladder wall thickness greater than 5 mm were associated with postoperative complications (all P < 0.05). Multivariate analysis showed that: Calot triangle adhesion (OR = 3.041, 95%CI = 1.422-6.507), anatomical variation (OR = 4.368, 95%CI = 1.764-10.813) and gallbladder wall thickening (OR = 2.827, 95%CI = 1.422-6.507). 95%CI = 1.274-6.275) were independent risk factors for complications after laparoscopic cholecystectomy (all P < 0.05). Conclusion: In order to reduce the occurrence of postoperative complications, the risk factors of LC should be well understood and the preoperative preparation should be made.
