Objective:To investigate the influencing factors of conversion to laparotomy or traditional laparoscopy in single-inci-sion laparoscopic cholecystectomy(SILC).Methods:The clinical data of 916 patients who underwent SILC from Jan.2011 to Dec.2021 were retrospectively analyzed.883 cases of SILC were successful,33 cases were converted.Reasons for conversion were analyzed and univariate and multivariate logistic analysis was performed on the corresponding indicators.Results:Among 33 converted patients,18 patients underwent laparoscopic cholecystectomy(due to bile duct variation in 7 cases,cystic artery variation in 2 cases,abdominal adhesion in 3 cases,large volume of gallbladder in 3 cases,thick gallbladder wall in 2 cases,and obesity in 1 case),and 15 patients underwent laparotomy(due to bile duct variation in 7 cases and abdominal adhesion in 8 cases).Univariate analysis showed that there were statistically significant differences in BMI,abdominal operation history,abdominal adhesion,gallbladder length>8 cm,gallbladder wall thickness>3 mm and anatomical variation(P<0.05).Multivariate logistic analysis showed that anatomic variation(OR=8.103,95%CI=2.967~22.128,P<0.001),BMI(OR=1.656,95%CI=1.391~1.971,P<0.001),abdominal adhesion(OR=3.782,95%CI=1.111~12.876,P=0.033),length of gallbladder>8 cm(OR=3.275,95%CI=1.266~8.467,P=0.014),thickness of gallbladder wall>3 mm(OR=3.520,95%CI=1.321~9.384,P=0.012)were independent risk factors for conversion of SILC(P<0.05),history of abdominal surgery(OR=1.733,95%CI=0.565~5.317,P=0.336)was not an independent risk factor(P>0.05).Conclusions:BMI,anatomical variation,gallbladder length>8 cm,gallbladder wall thickness>3 mm and abdominal adhesion are independent risk factors for SILC conversion.Preoperative assessment of patients'conditions should be made to select reasonable surgical programs and estimate intraoperative risks.
