Abstract: Objective To discuss the safety and feasibility of using aspirator to dissect passively the Calot's triangle in laparoscopic cholecystectomy (LC) for acute calculous cholecystitis. Methods A total of 408 patients with acute calculous cholecystitis underwent LC from January 2013 to January 2017 were divided into ultrasound knife dissection group (UK group, n=200) and the blunt suction apparatus dissection group (SA group, n=208) according to the dissection technique of Calot's triangle anatomy of the gallbladder. The clinical curative effects were compared between the two groups. Results There was no statistical difference in bleeding loss, conversion rate to open surgery, abdominal drainage rate, the postoperative hospital stays, the abdominal drainage duration, the rate of secondary stones of the common bile duct and the residual infection rate of the abdominal cavity between the two groups (P>0.05). Compare to the SA group, the dissection time of gallbladder triangle was longer and the injury rate of bile duct was higher in UK group(P<0.05), and the differences were statistically （P＜0.05）. No uncontrollable hemorrhea, gas embolism and puncture injuries were found in all cases. There was bile leakage in 10 cases (5.00%) and 2 cases (0.96%) in UK group and SA group respectively, and the difference was statistically (P＜0.05). No serious complications, deaths and unplanned reoperation occurred in both groups. All patients were followed up for an average period of (28.74±11.59) months. No biliary strictures, abdominal pain, fever and jaundice was found.ConclusionsThe dissection of Calot's triangle by suction apparatus is safe and reliable, and it does not increase the amount of bleeding, and is beneficial to shorten the operation time of dissection of Calot's triangle and reduce the incidence of bile duct injury and biliary leakage in LC for acute calculous cholecystitis. It is worthy of clinical application.
