Abstract
BACKGROUND: Detailed preoperative delineation of biliary tract anatomy plays a pivotal role in guiding surgeons completing laparoscopic cholecystectomy (LC) smoothly. Hereby, we retrospectively investigated the potential impact of preoperative magnetic resonance cholangiopancreatography (MRCP) on LC. PATIENTS AND METHODS: In this study, clinical data of LC patients who received conventional preoperative examinations from January 2008 to December 2010 (Ctrl group, n = 300) versus conventional examinations plus extra preoperative MRCP assessment between January 2011 and December 2013 (MRCP group, n = 300) were randomly retrieved. The ratios of conversion to open cholecystectomy and various postoperative morbidities were respectively analyzed. RESULTS: In total, the incidences of operation conversion, postoperative remnant cystic duct stone, and choledocholithiasis in the MRCP group were 12 (4.0%), 1 (0.3%), and 2 (0.7%), respectively, all evidently lower than those in the Ctrl group: 41 (13.7%), 7 (2.3%), and 9 (3.0%). In addition, the MRCP group also presented with fewer cases of bile duct injury and incidental gallbladder carcinoma compared with the Ctrl group (1 versus 5 and 1 versus 2, respectively), although none of the variances was statistically significant. CONCLUSIONS: Our results demonstrated that preoperative MRCP had a robust safeguarding effect on LC and deserves further promotion.
