Randomized controlled study of safety and curative effect of the mini-incision exploration of common bile duct

Abstract

Objective To evaluate the safety, feasibility and curative effect of mini-incision exploration of common bile duct. Methods In this study, 290 patients underwent min-incision exploration of common bile duct and 120 patients underwent open-incision exploration of common bile duct for bile duct stones and/or gallstones from 2005 to 2007. The iatrogenic bile duct injury, postoperative complication, residual stone, stone recurrence, therapeutic effect and clinical data were evaluated by randomized contrast analysis. Results Time of operation, bleeding, volume of drain pipe, time of recovery of intestinal peristalsis and average duration in hospital were significantly lower in the group of min-incision exploration(MCE) than in the group of open-incision exploration(OCE). The iatrogentic bile duct injury occurred in 5 cases(1.72%), residual stone in 10 cases(3.45%), stone recurrence in 15 cases(5.18%) in the group of MCE, and in 2 cases(1.67%), 4 cases(3. 33%) and 6 cases respectively in the group of OCE. There was no marked difference between the two groups. Howevert post-operative complications occurred in 17 cases(6.8%) and 16(13.3%) in the group of MCE and OCE, respectively. There was remarkable difference between the 2 groups(P<0. 05). Conclusion Mini-incision exploration of common bile duct is a feasible and safe method resulting in fewer complications of iatrogentic bile duct injury, stone recurrence and residual stone. Key words: Common bile duct diseases; Min-incision; iatrogentic bile duct injury; Stone recurrence and residual stone.
