[Laparoscopic cholecystectomy. 1203 cases with ultraselective cholangiography].

We present our experience at the University of Chile Hospital with 1203 cases of laparoscopic cholecistectomy between April 1991 and July 1993. In only 36 patients ultraselective cholangiography was performed. In 88 cases an endoscopic cholangiography was performed prior to surgery because of suspicion of choledocolithiasis. In 31 of them choledocolithiasis was demonstrated, and was successfully treated by papilotomy in 30 of them. In 5.8% of cases coversion to open surgery was necessary: 1.4% in chronic cholecystitis, 13% in acute cholecystitis and 39% in cases with fibrosis and esclerosis of gallbladder with or without biliary digestive fistula. The intraoperative cholangiography has been advocated as a manner to prevent the common duct injury. In spite of the small number of cases operated on with cholangiography, we haven't seen serious injuries of biliary tract; a carefully disection, as far away as possible of the common duct, is the best way to prevent iatrogenic lesions. Postoperative morbidity was present in 15 cases, 8 of them required a new operation. Two patients died.
