Primary duct closure combined with transcystic drainage versus T-tube drainage after laparoscopic choledochotomy

Abstract

Background: We compared the post-operative course and final outcome of primary duct closure combined with transcystic drainage with those of T-tube drainage.

Methods: We retrospectively analysed 112 consecutive patients treated with laparoscopic choledochotomy for common bile duct stones between February 2014 and December 2017. Primary closure with transcystic drainage was performed in 59 patients (group A), and laparoscopic choledochotomy with T-tube drainage was performed in 53 (group B). The primary endpoints were morbidity, the bile drainage quantity, operative time, post-operative stay, time until return to work and post-operative complications.

Results: The operation was successfully completed in all patients. The return to work period in group A was significantly shorter than that in group B (7.25 ± 1.27 versus 46.47 ± 3.86 days, P < 0.05). The average daily drainage was not significantly different between the two groups (P > 0.05). There was no significant difference in the operation time (133.75 ± 14.51 versus 132.21 ± 12.71 min) and duration of hospital stay (5.15 ± 1.23 versus 5.94 ± 0.95 days) between the two groups (P > 0.05). Bile leakage was seen in one T-tube removal patient. No complications were reported in group A. The patients were followed for 2 to 29 months (average: 10). Normal liver function and no stricture of the bile duct were detected with ultrasonography.

Conclusion: Primary closure of choledochotomy and subsequent transcystic drainage is a simple and less invasive procedure than T-tube placement.
