RT Journal Article SR Electronic T1 Late postcholecystectomy Mirizzi syndrome due to a sessile gall bladder remnant calculus managed by laparoscopic completion cholecystectomy: a feasible surgical option JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e228156 DO 10.1136/bcr-2018-228156 VO 12 IS 8 A1 Gunjan S Desai A1 Prasad Pande A1 Rajvilas Narkhede A1 Prasad Wagle YR 2019 UL http://casereports.bmj.com/content/12/8/e228156.abstract AB Postcholecystectomy Mirizzi syndrome (PCMS) is an uncommon entity that can occur due to cystic duct stump calculus, gall bladder remnant calculus or migrated surgical clip. It can be classified into early PCMS or late PCMS. It is often misdiagnosed and the management depends on the site of impaction of stone or clip. Endoscopy can be performed for cystic duct stump calculus. However, surgery is the treatment for remnant gall bladder calculus. Role of laparoscopic management is controversial. We present here a case of a 48-year-old woman with late PCMS due to an impacted calculus in a sessile gall bladder remnant following a subtotal cholecystectomy, managed with laparoscopic completion cholecystectomy, review the literature, provide tips for safe laparoscopy for PCMS and summarise our algorithmic approach to the management of the postcholecystectomy syndrome.
