title: Cystic duct remnant syndrome.
abstract: Post-cholecystectomy syndrome (PCS) is a common manifestation in patients with cholecystectomy. The patients exhibit a heterogeneous group of symptoms, such as upper abdominal pain, vomiting, gastrointestinal disorders, jaundice, and dyspepsia. Choledocholithiasis, biliary dyskinesia, and dilation of cystic duct remnants are common causes of these symptoms. The symptoms can recur after a symptom-free period following cholecystectomy or they can persist after surgery. Ultrasonography, computed tomography (CT), and magnetic resonance imaging scan, which are non-invasive methods of imaging, have a high sensitivity in detecting the causes of PCS. We report a case of an 84-year-old lady who came to the Ultrasound Department with recurrent episodes of abdominal pain following cholecystectomy. The gray-scale sonography showed a dilated cystic structure, which was confirmed as the duct remnant in follow-up contrast-enhanced CT.
