Strategies to decrease bile duct injuries during laparoscopic cholecystectomy.

BACKGROUND

Laparoscopic cholecystectomy (LC) has been performed clinically for more than 20 years. However, the incidence of bile duct injury (BDI) remains high despite attempts to prevent and reduce it. The aim of this study was to use an intraoperative unfavorable factors ratings system to identify unfavorable intraoperative factors and evaluate the effectiveness of application of the system in reducing BDI during LC.

PATIENTS AND

METHODS

Between January 2009 and December 2010, 780 patients who underwent LC were reviewed retrospectively, including 384 LC patients without graded treatment of intraoperative unfavorable factors (GTIUF) during 2009 and 396 LC patients with routine GTIUF during 2010.

RESULTS

BDI was decreased significantly after routine GTIUF (5 cases without GTIUF versus 0 cases with routine GTIUF; P=.029). There was no significant difference in postoperative morbidity and mortality between the two groups. The mean operation duration of the routine GTIUF group was prolonged significantly (P<.0001). Laparoscopic cholecystitis grading, GTIUF, and doctor's experience were important factors affecting the duration of operation (P<.0001, P<.0001, and P<.0001, respectively).

CONCLUSIONS

GTIUF is an effective method that emphasizes identification of the course of the extrahepatic bile duct and reduces the occurrence of BDI, especially for inexperienced operators.
