Endoscopic retrograde cholangiopancreatography(ERCP) could serve diagnostic and therapeutic purposes in patients with MS in addition to revealing the relationships between the cystic duct, the gallbladder, and the common bile duct(CBD). Cholecystectomy is a challenging procedure for a laparoscopic surgeon in patients with MS, and the presence of a cholecystocholedochal fistula renders preoperative diagnosis important during ERCP.AIM To evaluate cholecystocholedochal fistulas in patients with MS during ERCP before cholecystectomy.METHODS From 2004 to 2018, all patients diagnosed with MS during ERCP were enrolled in this study. Patients with associated malignancy or those who had already undergone cholecystectomy before ERCP were excluded. In total, 117 patients with MS diagnosed by ERCP were enrolled in this study. Among them, 21 patients with MS had cholecystocholedochal fistulas. MS was further confirmed during cholecystectomy to check if cholecystocholedochal fistulas were present. The clinical data, cholangiography, and endoscopic findings during ERCP were recorded and analyzed.RESULTS Gallbladder opacification on cholangiography is more frequent in patients with MS complicated by cholecystocholedochal fistulas(P < 0.001). Pus in the CBD and stricture length of the CBD longer than 2 cm were two additional independent factors associated with MS, as demonstrated by multivariate analysis(odds ratio 5.82, P = 0.002;0.12, P = 0.008, respectively).CONCLUSION Gall bladder opacification is commonly seen in patients with MS with cholecystocholedochal fistulas during pre-operative ERCP. Additional findings such as pus in the CBD and stricture length of the CBD longer than 2 cm may aid the diagnosis of MS with cholecystocholedochal fistulas.展开更多

Imaging and endoscopy play a key role in its diagnosis. CT scan helps to eliminate any malignant lesion of the bile ducts or liver hence comes in handy in the confirmation of Mirizzi syndrome. We hereby report a case of a Mirizzi syndrome complicating acute cholecystitis in a 41-year-old patient without any history of disease.展开更多
