ENDOSCOPIC MANAGEMENT OF BENIGN AND MALIGNANT BILIARY STRICTURES

BACKGROUND: If is now possible to manage most extrahepatic bile duct s trictures, benign or malignant, using endoscopic retrograde cholangiop ancreatography (ERCP) with endoscopic dilatation and stenting, METHODS : Over a 5-year period we treated 218 patients with strictures of extr ahepatic bile ducts, Eighty-six patients had benign biliary stricture, Endoscopic treatment was performed in 67 (78%) of these patients, Ope n surgical biliary drainage was preferred in 12 patients (14%), and 7 patients (8%) were managed conservatively without stenting or surgery. One hundred and thirty-two patients had malignant biliary stricture. One hundred and one patients (77%) underwent endoscopic stent placemen t. Thirty-one patients (23%) underwent surgery for potential curative resection after diagnostic ERCP. The average life span in the malignan t stricture group was 5 months (range 0.1 to 25 months) after the init ial endoscopic procedure, RESULTS: Altogether 313 endoscopic procedure s in 218 patients were performed for benign and malignant bile duct st rictures. Complications included hemorrhage in 8 (3%), pancreatitis in 10 (3%), and suspected retroperitoneal perforation in 2 (0.6%), There were no ERCP related deaths; one patient died of uncontrolled bleedin g from transhepatic stenting, In benign strictures, there has been no recurrence of strictures after the last stent removal with a mean foll owup of 21 months (range 0.1 to 31 months), Ali complications were suc cessfully treated conservatively. CONCLUSIONS: Endoscopic management o f benign and malignant biliary stricture is possible with minimal morb idity and mortality and should be considered an acceptable option to s urgical management.
