Mirizzi syndrome in a patient with partial gastrectomy with Billroth II anastomosis: A case report.

Abstract

INTRODUCTION:

Mirizzi Syndrome (MS) is a common bile duct (CBD) obstruction caused by extrinsic compression from an impacted stone in the cystic duct or infundibulum of the gallbladder. Radiological evaluation may mistake it for CBD stones in jaundiced patient, especially in those who have altered anatomy of upper gastrointestinal (e.g. sub-total gastrectomy - STG - with Billroth I or II anastomosis).

PRESENTATION OF CASE:

A 69-year-old male with a history of STG Billroth-II 25 years prior, accessed hospital for abdominal pain and jaundice with increasing in hepatic laboratory tests. Ultrasound of abdomen, CT scan and MRCP diagnosed CBD stones, so endoscopic retrograde cholangiopancreatography (ERCP) was performed, using a gastroscope to reach papillary region and to achieve cannulation of biliary duct. During cholangiography patient resulted affected by Mirizzi syndrome type I, so laparoscopic cholecystectomy was performed and cystic duct was moved away.

DISCUSSION:

This rare case shows how it's easy to delay the correct treatment when a wrong radiological diagnosis is made. Moreover, ERCP remains a challenging procedure in patients with altered anatomy, such as STG B-II, and in this case gastroscope was needed for cannulation, due to the need of frontal view.

CONCLUSION:

This rare case report highlights the importance of not forgetting MS in the differential diagnosis of biliary obstruction, especially in those patients with upper GI altered anatomy. Physicians with expertise in ERCP should always consider altered anatomy as a factor which may confuse radiologist in diagnosis, so in this case MS may be discovered or confirmed at ERCP.
