ObjectiveTo investigate the clinical value of the application of laparoscopic electrical hook combined with ultrasonic knife in gallbladder triangle fine anatomy for laparoscopic cholecystectomy (LC). MethodsA total of 76 patients with gallstones were treated with electrical hook combined with ultrasonic knife to conduct fine anatomy in gallbladder triangle for LC. Results73 patients successfully underwent LC surgery. Among them, 6 cases conducted LC combined with laparoscopic appendectomy (LA), 2 cases had unclear severe gallbladder triangle anatomy due to Mirizzi syndrome caused adhesion, 1 case was transferred to laparotomy surgery due to cystic necrosis and undistinguished three duct structure. The operative time was 35 to 96 min,with an average of 49.5 min,the intraoperative blood loss was 6 to 70 mL, with an average of 19.5mL.No intraoperative bile duct injury occurred. Five cases conducted drainage by placing rubber drainage tube. the length of Hospital stay was 4-7 d, with an average of 4.5d,respectively. Postoperation follow-up performed for 3 to 9 months, with an average 7.6 months,and no complications such as bile leakage,biliary stricture or intraperitoneal abscess occurred. ConclusionThe electrical hook combined with ultrasonic knife was used to conduct fine anatomy in gallbladder triangle for LC, which can accurately discern gallbladder region, especially the three duct local anatomical relations of cystic duct, common hepatic duct and common bile duct in gallbladder triangle region, thus the wound was small in gallbladder removal, can effectively prevent bile duct injury, is safe and feasible, and has good clinical values.
