DIAGNOSTIC-IMAGING MODALITIES IN ENDOSCOP IC CHOLECYSTECTOMY

Purpose: To study the diagnostic value of radiological imaging modalit ies in patients undergoing endoscopic cholecystectomy. Patients and Me thods: In 286 patients with endoscopic cholecystectomy ultrasound and intravenous cholecystography was performed for preoperative work-up. P ostoperatively all patients were examined with ultrasound. Results: ER CP showed a stone in the common bile duct in 12 patients with suspecte d stones on ultrasound, cholecystography or laboratory values. All 12 patients were treated with papillotomy. Postoperative ultrasound detec ted increasing fluid in the peritoneal cavity in three patients. Lapar otomy of one patient showed bleeding from the cystic artery, in the se cond patient, injury of the right bile duct. One patient showed an acc essory hepatic duct, another patient demonstrated pancreatitis. Conclu sion: Ultrasound and intravenous cholecystography are suitable for pre operative imaging. Postoperative ultrasound is useful in detecting com plications.
