Emergency open surgery with a duodenotomy and successful removal of an impacted basket following a complicated endoscopic retrograde cholangiopancreatography procedure: a case report

BACKGROUND: Current management of choledocholithiasis entails the use of endoscopic retrograde cholangiopancreatography (ERCP) and clearance of the common bile duct. A rare complication of this procedure is the impaction of the basket by a large stone, which necessitates lithotripsy. Here we report a case of an impacted basket during ERCP, which was managed by open surgery with a duodenotomy and the manual removal of the basket. CASE PRESENTATION: A 79-year-old Caucasian man was admitted to our department with yellowish discoloration of urine, skin and eyes. Abdominal ultrasonography showed a slightly thickened gallbladder, multiple gallbladder stones, dilated intrahepatic bile ducts and extrahepatic bile extending to 1.1 cm. A computed tomography (CT) scan demonstrated a stone in the common bile duct, which caused dilation of the biliary ducts. The patient was diagnosed with obstructive jaundice secondary to choledocholithiasis; and underwent an ERCP, a sphincterotomy and stone extraction. Four days following discharge, the patient was readmitted with jaundice, abdominal pain, vomiting and fever. He was diagnosed with ascending cholangitis and treated initially with antibiotics. A second ERCP revealed a dilated common bile duct and choledocholithiasis. Stone removal with a basket failed, as did mechanical lithotripsy. Finally, the wires of the basket were ruptured and stacked in the common bile duct together with the stone. During exploratory laparotomy, adhesiolysis, a Kocher maneuver of the duodenum and a subtotal cholecystectomy were performed. Choledochotomy did not succeed in removing the impacted wires together with the stone. Therefore, a duodenotomy and an extension of the sphincterotomy were performed, followed by high-pressure lavage of the common bile duct to remove additional small biliary stones. The choledochotomy and duodenotomy were closed by a one-layer suture, and a prophylactic gastroenterostomy was performed to prevent leakage from the common bile duct and the duodenum. The postoperative course was satisfactory. CONCLUSIONS: This is the first report in the literature of removal of an impacted Dormia basket through the papilla by performing a duodenotomy and an extension of the sphincterotomy, followed by gastroenterostomy.
