To explore the clinical value of "stripping" technique in laparoscopic cholecystectomy (LC).

Clinical data of 372 patients who underwent LC using "stripping" technique in the Lanzhou University Second Hospital from October 2014 to December 2018 were retrospectively analyzed. The informed consents of all patients were obtained and the local ethical committee approval was received. Among them, 131 patients were male and 241 female, aged (48±13) years on average. 336 patients were diagnosed with cholecystolithiasis complicated with chronic cholecystitis, 22 cases with acute onset of chronic cholecystitis, 12 cases with acute suppurative cholecystitis and 2 cases of acute gangrenous cholecystitis. All patients underwent LC with the innovative "stripping" technique, the Calot's triangle dissecting points of the gallbladder was made deflected to the neck of gallbladder, the inner tissues of anterior and posterior Calot's triangle were dissected layer by layer, the anatomical sites of the left, right hepatic duct, common bile duct, cystic duct, gallbladder artery and sentinel lymph node were pinpointed, and subsequently the cystic duct and gallbladder artery were severed. The perioperative situation of the patients were observed.

LC using "stripping" technique in all the patients were completed successfully, and no patient was converted to open surgery. The median operation time was 35(20-50) min. Intraoperative blood loss was 15(5-55) ml. The length of postoperative hospital stay was 5(3-7) d. No death occurred during the perioperative period. No bile leakage, biliary stenosis and other postoperative complications occurred.

"Stripping" technique in the LC is a safe, effective and easy-to-learn procedure, which can effectively prevent the incidence of complications, such as bile leakage and biliary stenosis, etc.
