Colonoscopic treatment of obstructive appendicitis caused by dislocation of a biliary stent.

A 65−year−old woman was admitted to the emergency room with right lower quad− rant abdominal pain, nausea, vomiting, fever, and chills. She had a history of com− plicated cholecystectomy with secondary stenosis of the common bile duct, which was treated with biliary stents for 24 months. On physical examination, she was febrile (38.6 8 C), with tenderness in the right lower quadrant and a negative psoas sign. Laboratory tests revealed a leukocytosis of 15.2 ” 109/l and an elevat− ed C−reactive protein level at 8.2 mg/l. The bilirubin, alkaline phosphatase, and gamma−glutamyl transferase levels were within normal limits.
