METHOD OF PREVENTING LEAKAGE OF ESOPHAGOGASTRIC ANASTOMOSIS Russian patent published in 2023 - IPC A61B17/11 A61M25/01 A61M1/00 

FIELD: medicine; thoracic surgery; oncology; gastroenterology.

SUBSTANCE: during the thoracic stage of the Lewis procedure, based on the size of the gastric graft, side holes are made at the distal end of the nasogastric tube. The probe is passed into the lumen of the gastric graft to the outlet of the stomach, while the proximal side hole is set 3 cm below the area of the esophageal-gastric anastomosis. Depending on the volume of the patient's gastric graft, 150–350 ml of 0.9% sodium chloride solution, stained with a solution of brilliant green, are administered. The tightness of the seams is assessed under visual control. In the early postoperative period, after eating food by mouth, the nasogastric tube is closed for 2 hours, followed by connecting the Redon aspiration system to the proximal end of the tube. The feeding technique is repeated 6–7 times a day with a dynamically increasing volume of food consumed.

EFFECT: method allows to check the tightness of the sutures of the esophageal-gastric anastomosis, identify the presence of defects, verify the double safety margin of the anastomosis and provide guarantees of safe early sipping nutrition after the Lewis operation, allows to reduce the incidence of postoperative complications from the anastomosis, which will reduce the patient’s time in the hospital, and will also improve the quality of life of patients.
