[Use of lasers in the treatment of bile duct obstruction of benign origin].

A comparison of effects of surgical treatment of two groups of patients with obstruction of bile ducts of benign genesis was made. In the 1st group (91 patients) the intravenous laser irradiation of blood was used. In the 2nd group (93 patients) the laser irradiation was not performed. The authors consider that the intravenous laser irradiation of blood in the surgical treatment of patients with obstruction of bile ducts of non-tumor etiology contributes to reduction of the amount of complications and less lethality rate.
