Risk Factors of Postoperative Complications in Laparoscopic Cholecystectomy for Acute Cholecystitis.

Abstract

Introduction:There are often cases with postoperative complications after laparoscopic cholecystectomy (LC), resulting in severe consequences. This study aimed to identify potential risk factors of postoperative complications in cases of LC for acute cholecystitis.Materials and Methods:A total of 423 patients with cholecystitis underwent LC. We divided the patients into two groups: group without postoperative complications (Group A) and group with postoperative complications (Group B). Pre-operative findings, surgical findings, and the methods for evaluating the risk of peri-operative complications were compared between the two groups with a univariate analysis. Independent risk factors of postoperative complications were then evaluated in a multivariate analysis with the factors shown to be statistically significant in the univariate analysis.Results:A Physiological and Operative severity Score for enUmeration of Mortality and morbidity (POSSUM) of ≥ 48.3 and moderate or severe cholecystitis were independent risk factors of postoperative complications in LC.Conclusions:This study indicated that POSSUM morbidity and moderate or severe cholecystitis were potential risk factors of postoperative complications. The pre-operative management of the general condition and cholecystitis using antibiotics, infusion, percutaneous transhepatic gallbladder drainage, and other approaches may be significant for the prevention of postoperative complications. Once the POSSUM morbidity reaches the threshold after LC, postoperative management becomes difficult, so strict control of the general condition should be performed.
