Human fibrin sealant reduces post-operative bile leakage of primary closure after laparoscopic common bile duct exploration in patients with choledocholithiasis.

Context: Primary closure of the common bile duct (CBD) without drainage is considered a suitable approach after laparoscopic CBD exploration (LCBDE); however, the risk of post-operative bile leakage is high. Up to now, it has not been clear whether human fibrin sealant can reduce post-operative bile leakage of the primary suture. Aims: In this study, we evaluated the role of human fibrin sealant in primary closure of the CBD after LCBDE. Subjects and methods: Patients with choledocholithiasis who had undergone primary duct closure of the CBD after LCBDE were divided into two groups according to whether fibrin sealant was used. Statistical analysis used: Fisher's exact test or the Chi-square test was used for categorical variables to calculate frequencies and percentages between the groups. The Student's t-test was used to compare the means of the continuous variables between the groups. Results: The human fibrin sealant group had a lower rate of post-operative bile leakage compared to the other group (P < 0.05). There were no significant differences in additional parameters such as operative time, post-operative stay duration, time to drain removal, bile duct stenosis, acute allergic reaction and overall mortality. Conclusions: Human fibrin sealant can reduce post-operative bile leakage in primary closure of CBD after LCBDE in patients with choledocholithiasis.
