[Dissolution of choledochus stones with heparin-saline solution].

In a series of 336 cholecystectomies a revision of the bile ducts was necessary in 60 cases (18%). One to three residual concrements were evident in 6 patients from control cholangiograms made 8-10 days postoperatively (1.8%). Three of these patients were successfully reoperated. The remaining three were treated by irrigation with a herparin solution: the stones of two patients disappeared in 13 and 20 days, respectively. The third patient had to be reoperated due to septic fever on the 13th day, whereby soft, decayed material could be extracted. All patients had a complication-free recovery. Check-ups made six to twelve months later revealed painfree patients and normal cholangiographic values.
