[Choledocholithotomy and papillosphincterotomy in surgery of the bile ducts]

The Authors argue about the different surgical choices feasible in case of CBD stones. They consider a case-record of 74 patients that underwent, from January 1988 to June 1990, choledocholithotomy or transduodenal sphincterotomy for non-neoplastic pathology of the CBD in the I Divisione di Chirurgia Generale OO.RR. Bergamo. Analysis of the data shows a significant pre-operative alteration of the gamma-GT plasmatic levels. That represent a risk-index useful to suspect a silent CBD lithiasis. The good results attained with the choledocholithotomy and with the transduodenal sphincterotomy show the efficacy of both methods, that keep up different indications. The Authors point out the efficacy of the antibiotic prophylaxis in the prevention of the operative infections.
