METHOD FOR FORMATION OF THE SUBMUCOSAL TUNNEL DURING ENDOSCOPIC SURGICAL INTERVENTIONS FOR ACHALASIA OF THE ESOPHAGUS CARDIA

摘要

FIELD: medicine. ;SUBSTANCE: invention relates to medicine, namely endoscopy and surgery. The method involves submucosal injection of a mixture of gelatin solution and 0.4% indigocarmine solution using an endoscopic injector through the channel of an endoscopic knife. A Haemoblock solution is added to the mixture for submucosal administration, and the proportions of the components of the mixture are in the ratio of 1:2:0.04-0.07 of Haemoblock solution, gelatin solution and indigocarmine solution, respectively. The injection is carried out through an endoscopic injection needle with a diameter of 25 G and a length of 4 mm, making injections to form a tunnel every 3-5 mm, injecting 1-2 ml of solution into the submucosal layer with each injection. ;EFFECT: method reduces the risk of complications in the formation of the submucosal tunnel of hollow organ tissues by creating a time-prolonged comfortable surgical field in the manipulation zone in the absence of bleeding, which, in turn, contributes to the effectiveness of endoscopic surgical interventions in the formation of the submucosal tunnel. ;1 cl, 2 ex
