Abstract:
Laparoscopic common bile duct exploration (LCBDE) for choledocholithiasis is a
popular option in many surgical institutes. Decompression of biliary system via T-tube post supraduodenal choledochotomy has been the traditional surgical practice. Primary closure of common
bile duct (CBD) has been shown to reduce hospital stay but bears a risk of bile leak. We conducted
a prospective randomized trial to compare complications and length of stay in patients undergoing
biliary stent insertion versus T-tube drainage following LCBDE via choledochotomy.
Methods and Procedures: The study involves 52 patients with choledocholithiasis who underwent
LCBDE and decompression of the biliary system by either antegrade biliary stent or T-tube
insertion. A 7 French biliary stent (9 “10 cm long) have been placed in 27 patients (group I), T-tube
insertion have been used for 25 patients (group II). The length of hospital stay and complications
were recorded. All transcystic explorations were excluded.
Results: There were no significant differences between groups with respect to age, sex,
comorbidities, number and size of CBD stones. Postoperative complications have been observed
in 4 patients (16%) in the T-tube group (one patient needed reoperation for dislocation of T-tube), and in 1 patient (3.7%) in the biliary stent group (p < 0.05). The mean postoperative hospital stay
was 3.2 ± 1.2 days for group I, and 6.2 ± 1.7 days for group II (p < 0.05).
Conclusions: Our results showed a reduction of length of hospital stay and morbidity following
stent insertion compared to T-tube drainage. Also, the use of biliary stent after LCBDE can reduce
costs and increase patient satisfaction.
