Abstract:ObjectiveTo explore the application value of critical view dissection guided by Rouviere's sulcus in laparoscopic cholecystectomy （LC）. MethodsRetrospective analysis was performed on 232 patients received LC in Yueyang Hospital of Integrated Traditional Chinese and Western Medicine from August 2018 to July 2020. Patients underwent critical view dissection guided by Rouviere's sulcus were served as study group（n=141）, and patients underwent traditional anatomical dissection as control group （n=91）. The operation time, intraoperative bleeding, the number of drains, bile duct injury and laparoscopy converted to laparotomy, the time of first postoperative feeding and exhaust, the number of postoperative infections, the time of discharge were compared between two groups. ResultsCompared with the control group, the study group had shorter operation time ［（50.07±5.91）min vs（60.48±13.30）min, t=8.14, P＜0.05］, lower intraoperative bleeding ［（13.42±7.93）mL vs （25.02±21.17）mL, t=5.90, P＜0.05］, lower placement drainage rate, bile duct injury rate, postoperative infection rate, and earlier postoperative feeding, exhaust, and discharge time, with statistically significant differences （P＜0.05）. ConclusionCompared with traditional anatomical dissection method, critical view dissection guided by Rouviere's sulcus in LC can shorten surgical time, reduce intraoperative blood loss, reduce the probability of bile duct injury, and accelerate postoperative recovery, which is worthy of clinical application and promotion.
