[Treatment of choledocholithiasis at the General Hospital of Mexico, S.S].

We present two years of our surgical experience in the Gastroenterologic department of General Hospital of Mexico city; we studied prospectively 23 patients with choledocholithiasis diagnosed preoperatively and postoperatively, 18 females (78%) and 5 males (22%). Diagnosis were performed preoperatively by sonogram, intravenous cholangiography and/or endoscopic retrograde pancreatocholangiography in 19 cases, and postoperatively in four cases. In 22 cases we performed colecistectomy with choledocotomy, extraction of calculi and placement of a "T" biliary catheter. In only one case was necessary a choledoco-duodenal anastomosis. We observed morbility in 3 cases (13%), and a patient died postoperatively (4%). The postoperative follow up was satisfactory in 83% of these cases.
