[Endoscopic treatment of obstructive jaundice at a second level national health system hospital]

The difficulty of performing endoscopic retrograde cholangiopancreatography (ERCP) in our patients in the reference hospitals within a few days of diagnosis of obstructive jaundice led us to perform this technique in our center. We expected to perform a small number of ERCP annually. We analyzed the success rate of initial biliary drainage and the complications of this procedure.

We performed a retrospective study. From 1997-1999 we carried out 240 ERCP. In 128 patients, 140 ERCP were performed for obstructive jaundice (58,3%). The final diagnosis was choledocholithiasis in 69 patients (54%), tumors in 35 (27%), dilatation of the biliary tract without obstruction at cholangiography in 21 (17%) and benign stenosis of the biliary tract in 3 (2%).

The mean procedure time for ERCP was 5.26 ( 2.8) days. Cholangiography was successfully performed in 117 patients (91.4%). Effective therapeutic endoscopy was performed in 111 patients (86.7%). Jaundice was resolved in 62 patients (90%) with choledocholithiasis, 55 (80%) by stone removal and in 7 (10%) by prosthesis. Resolution was also achieved in 25 (71.5%) tumors, mainly by prosthesis, and in 100% of patients with benign stenosis. In all patients with dilatation of the biliary tract without obstruction, biliary sphincterotomy was performed. Complications were found in 15 patients (11.7%) and two (1.56%) died.

The majority of patients with obstructive jaundice can be satisfactorily treated in a center with our characteristics. However, in tumors, the figures for drainage were slightly lower than those reported in the medical literature.
