Preoperative diagnosis of Mirizzi syndrome:a report of 15 cases / 中国普通外科杂志

ABSTRACT

Objectives To evaluate the methodology of preoperative diagnosis for Mirizzi syndrome. Methods Fifteen cases of Mirizzi syndrome were retrospectively investigated. The data of semeiology and imaging including B-type ultrasound, endoscopic retrograde cholangiopancreatography (ERCP) and MR cholangiopancreatography (MRCP) were compared with each other and analyzed. Results Preoperative data were consistent with and suggestive of Mirizzi syndrome in 93% (14/15) of cases, and in 67% (10/15) of cases, respectively. Conclusions Preoperative B-type ultrasound is the primary examination. ERCP and MRCP further elevate preoperative definite diagnosis. In patients with preoperative tentative diagnosis of Mirizzi syndrome, jaundice lasting for more than 7 week is suggestive of cholecystocholedochal fistula.
