BACKGROUND Mirizzi syndrome is biliary obstruction caused by extrinsic compression of the distal common hepatic duct by a gallstone in the adjacent cystic duct or infundibulum of the gallbladder. Post-cholecystectomy Mirizzi syndrome (PCMS) is Mirizzi syndrome in the post-surgical absence of a gallbladder. This case report of PCMS and review of the literature illustrates the diagnostic and therapeutic challenges in evaluating and managing Mirizzi syndrome. CASE REPORT A 44-year-old female with a remote history of laparoscopic cholecystectomy presented to a community teaching hospital with acute and severe upper abdominal pain and tenderness. Laboratory data revealed markedly elevated transaminases of a magnitude most often observed with hepatitis from acute viral infection, ischemia, or exposure to a hepatotoxin. PCMS was ultimately diagnosed at endoscopic retrograde cholangiopancreatography after being misdiagnosed as choledocholithiasis on magnetic resonance cholangiopancreatography. After transfer to an academic quaternary care referral hospital, the patient's extrahepatic biliary tree was reportedly cleared of gallstones following endoscopically-directed shock-wave lithotripsy performed at repeat -endoscopic retrograde cholangiography. CONCLUSIONS Recognizing post-cholecystectomy syndrome, in general, and PCMS, in particular, is critical when caring for patients presenting with persistent or recurrent symptoms or signs of biliary obstruction following cholecystectomy. Expediently identifying and definitively relieving the biliary obstruction, while limiting the risk of iatrogenic complication, is the priority when caring for patients with PCMS.

We present a case of an unexpected cause of bowel ischemia in an intensive care unit patient with herpes simplex virus encephalitis who required an operation. A 79-year-old lady was being worked up and treated for encephalitis with antibiotics and an antiviral. On Day 13, she developed abdominal pain, and an ultrasound showed cholelithiasis but no cholecystitis; thus conservative treatment was advocated. By Day 18, pain localized to the right iliac fossa, and she had an emergency laparotomy that showed bowel ischemia and perforation of the caecum with the cause being a terminal ileal adhesional band. An extended right hemicolectomy and ileostomy was performed. Patients with significant comorbidities who are intensive care unit-dependent may still have unexpected clinical challenges. We advocate an increased clinical vigilance in this cohort for unexpected life-threatening presentations such as bowel ischemia and more specifically the cause of the bowel ischemia.

Liver involvement is found in nearly 40% of children with sickle cell disease. The most frequent complication is cholelithiasis. The most severe complication is acute hepatic crisis, with symptoms ranging from increasing jaundice to multiple organ failure and death. The emergency and mostly efficient treatment is exchange transfusion. Chronic cholangiopathy is increasingly recognized, with autoimmune features in most cases, worsened by chronic ischemia. Transfusion-related iron overload is not yet a concern in children, and hepatotoxicity of iron chelators is rare. We propose recommendations to prevent, explore, and treat these complications. We emphasize the close collaboration required between hepatologists and specialists of sickle cell disease.
