[The thoracic surgeon and the management of the bronchial biliary fistula of hydatid origin]

The bronchial biliary fistula surgery is a major one, always going with a higher rate of complication especially in case of bile duct obstruction. The aim of this study is to find out the contribution of endoscopic sphincterotomy while reporting the results of surgical treatment of bronchial biliary fistulae by exclusive thoracotomy.This was a retrospective study, which took place in the Department of Thoracic Surgery, University Hospital Hassan II, from January 2009 to March 2016. The parameters studied in connection with the bronchial biliary fistula of hydatid origin were: age, sex, origin, history of surgery especially for hepatic hydatid cyst, term of bilyptysie, imaging results, preoperative cholangiography indications, surgical treatment modalities and patients trends.A sample of 12 patients was included (6 men and 6 women) with an average age of 44 years old, with a gap spanning between 17 and 81 years. Seven patients had at least a history of hepatic hydatid surgery. The biliptysie was the main symptom in 8 patients. A biological cholestasis syndrome was found in 6 patients. The thoracoabdominal CT scan performed on all patients comes out with results in 100% of cases. Four patients received endoscopic retrograde cholangiography that allowed them to release the bile duct completely by sphincterotomy with extraction of hydatid membrane in one patient and with development of a biliary stent in another patient. The incision was a low posterolateral thoracotomy in 10 patients that went under surgery. It has allowed to deal in one-time liver and lung injuries combined with diaphragmatic breach repair. Inside the group of patients that went under surgery, the postoperative results were simple in 8 cases. We have noted an overall mortality rate of 18.2%.Bronchial biliary fistula surgery complications remains considerable despite the progress of diagnostic imaging. Preoperative endoscopic sphincterotomy is a milestone in the handling of this surgery. It may even be suggested as exclusive therapy in inoperable patients with significant biliptisy.
