title: [Evaluation of 3757 cases of open biliary tract surgery before the introduction of the laparoscopic method (basis for comparison)].
abstract: 3757 elective nonmalignant biliary tract operations are evaluated retrospectively in the 17-year period from January 1, 1974 to December 31, 1990. The operations were divided into four periods according to development and frequency of intraoperative diagnostics: I. period without examinations of common bile duct (511 operations), II. selective period (848 operations), III. routine period (906 operations), IV. restricted routine period (1492 operations). The authors experienced improvement in their results if they carried out intravenous cholangiography routinely. Comparing eight characteristic factors they believe that their results are favourable if they performed intraoperative common bile duct examinations (manometry, cholangiography, flow rate measurement) in 39.6% rate and if they employed praeoperatively EST if necessary. They propose the selective intraoperative cholangiography. In the period of 39.6% intraoperative cholangiography (restricted routine period) they found common bile duct stones in 10.7%, unsuspected stones in 0.4%, retained stones in 1.6%, unnecessary choledochotomies in 2.7% and intraoperative common bile duct injuries in 0.2%. The overall mortality rate was 0.4%. They deal with the intraoperative differential diagnostics of Vater papilla stenosis and spasm.
