[Laser photodynamic therapy of septic wounds].

Two comparable groups, 60 patients in each, were included in the study. Localization and area of the wounds, as well as basic treatment were equal in these groups. Patients of the main group received the additional photodynamic therapy with chlorine photosensibilizing agent.

[The diagnosis of obstructive cholangiopathy in newborn infants].

To establish an early diagnosis of obstruction of the extrahepatic bile ducts in 12 newborn infants with jaundice the authors applied hepatobiliary scintigraphy and transcutaneous cholecystocholangiography under control of laparoscopy (2 patients). Atresia of the bile ducts was diagnosed in 4 children, which was confirmed during the operation; in one of these patients scintigraphy undertaken 3 weeks after the intervention showed restoration of the flow of bile into the intestine. In 5 cases a mechanical component of jaundice was not found and in 2 newborn infants the results of scintigraphy proved to be poorly informative.

[Use of CO2 laser for surgical debridement of wounds].

The article deals with the results of experimental research in determining the optimum parameters of laser radiation for surgical debridement of wounds and the techniques of its performance. It presents the results of treatment of 137 patients with incised wounds of various localization with the use of a carbon dioxide laser beam. Sterility of the wound surface was produced in 96-97% of cases after wound debridement with a laser beam; uncomplicated healing of wounds was noted in 90% of cases.

[Characteristics of wound process after high-energy laser debridement and enzyme treatment].

The results of ++clinico-bacterial examination of 168 patients provide evidence for the efficacy of CO2-laser treatment of a purulent wound; it reduces contamination of the tissues, 1,000-10,000-fold as a result of which surgical debridement of the purulent wound is completed in most cases by the application of a primary suture. The use of immobilized proteolytic enzymes in the postoperative period facilitates further cleansing of the wound, prevents the development of secondary infection, accelerates the change of the wound process to the phase of regeneration, promotes an uneventful postoperative course and healing of the wound within a lesser period as compared to the control group.

[Co2 laser treatment of epithelial passages and cysts of the coccyx].

The article analyses treatment of 312 patients among which 156 were treated with the use of a CO2 laser and 156 by the traditional method. Study of the results showed that with the use of the CO2 laser the duration of in-patient treatment after radical operation was reduced by 5 days and out-patient rehabilitation by 13 days. the number of postoperative complications reduced considerably, single-stage radical operation could be carried out in the acute period of the disease, an operation for excision of a suppurating cyst could be completed by applying primary sutures with complete closure of the wound in 71.
