Efficacy of laparoscopic surgery on the treatment of Dong Type C adult biliary dilatation

Objective To investigate the technical and therapeutic effects of laparoscopic surgery for adult patients with Dong Type C bile duct dilatation. Methods A retrospective cohort study approach was used. The clinical data of 47 patients with Dong Type C adult biliary dilatation who underwent surgery in Fujian Provincial Hospital from January 2014 to December 2017 were collected. There were 12 males and 35 females. The age ranged from 16 to 68 years, with a median age of 30 years. According to different surgical methods, the patients were divided into the laparoscopic group (treated with laparoscopic cyst excision and Roux-en-Y hepaticojejunostomy, n=21) and the open group (treated with traditional open operation, n=26). The intraoperative blood loss, complication rate, operation time, postoperative intestinal function recovery time and postoperative hospital stay were observed. Measurement data with normal distribution were expressed as mean ± standard deviation (Mean±SD) and analyzed by t test. Comparison of count data was done by the chi-square test. Results There was no perioperative deaths in either group. There was no significant difference in intraoperative blood loss and complication rate between the two groups (P>0.05). The operation time of the laparoscopic group was significantly longer than that of the open group[ (333.7±61.1) min vs (235.9±64.3) min], with statistically significant difference between graps (P=0.000). The recovery time for the intestinal function of the laparoscopic group was significantly shorter than that of the open group [(2.2±0.5) d vs (2.9±0.6) d], with statistically significant difference between groups (P=0.000). The postoperative hospital stay in the laparoscopic group was significantly shorter than the open group [(7.1±1.8) d vs (12.0±5.9) d], with statistically significant difference between groups (P=0.001). Conclusion For adult biliary dilatation patiens with Dong Type C, laparoscopic surgery is safe and feasible with the advantages of mini-invasive and quick recovery.
