Complete situs inversus viscerum (SIV) is a rare congenital condition, defined by a left-right transposition of all viscera with dextroposition of the heart. In patients with SIV that requires endoscopic intervention, namely endoscopic retrograde cholangiopancreatography (ERCP), the left-right coordination can be technically demanding even with skilled endoscopist. We report a case of a patient with underlying SIV who presented with septic shock secondary to ascending cholangitis compounded with a malaria infection. Despite the ascertainment of a relatively large Common Bile Duct (CBD) stone, ERCP and stenting were pursued as an initial treatment modality in view of the clinical presentation of cholangitis and COVID-19-related delays in surgical intervention at our center. This case is unique as the patient was maintained in a supine position throughout the procedure. The patient underwent a successful ERCP procedure followed by a CBD Exploration and cholecystectomy 2 weeks later. A key factor that contributed to the success of this procedure was the combined utilization of a rotatable sphincterotome and extractor balloon which assisted with cannulation and shortening manoeuvre of the duodenoscope to facilitate biliary stenting.
