[Late stage stenoses of bile ducts after iatrogenic bile duct injuries following cholecystectomy].

INTRODUCTION

Iatrogenic bile duct injuries represent a severe complication after cholecystectomy. For the attending physician therapy and management of these injuries are a challenge. Inadequate and delayed treatment can lead to stenoses at a late stage, which can necessitate further surgical intervention.

METHODS

In a study data of 74 patients, who were treated in our clinic for bile duct injuries following cholecystectomy, were analysed retrospectively.

RESULTS

A total of 8 patients with late stage bile duct strictures following iatrogenic bile duct injury including the subsequent therapy could be identified. The data of these patients were analysed in respect of cause and strategies to prevent late stage stenoses. In 62 patients the bile duct injury occurred following laparoscopic and in 12 patients following open cholecystectomy. In 16 patients the injury was combined with a vascular lesion. The interval between primary intervention and definitive therapy was 11 days in 53 patients and 1-15 years in 21 patients. In 8 patients the reason for the re-operation after a long interval (1-15 years) was a late stage stenosis. A hepatico-jejunostomy was performed subsequently and during follow-up 5 / 8 patients were symptom-free; 7 patients were re-operated due to a stenosed primary biliodigestive anastomosis and 3 patients each due to atrophy of the right liver lobe and recurrent cholangitis. One patient complained of recurrent cholangitis and a further patient of symptoms due to adhesions.

DISCUSSION

If treated inadequately bile duct injuries occurring during cholecystectomy can in the long-term lead to considerable problems such as recurrent cholangitis, late stage stenoses and even to secondary biliary cirrhosis. Therefore, a complex inter-disciplinary therapeutic concept aiming at timely treatment is necessary.
