METHOD FOR FORMING AN ANTIREFLUX MECHANISM FOR THE TREATMENT OF GASTROESOPHAGEAL REFLUX DISEASE IN OBESE PATIENTS AFTER A LONGITUDINAL RESECTION OF THE STOMACH Russian patent published in 2023 - IPC A61B17/00 

FIELD: medicine; surgery; gastroenterology.

SUBSTANCE: trocars are installed. The gastroesophageal junction is brought down into the abdominal cavity in such a way that the abdominal part of the esophagus is at least 3 cm free in the abdominal cavity. Then cruroraphy is performed. The round ligament of the liver is mobilized: the ligament is cut off from the anterior abdominal wall along its entire length, crossed until it enters the liver and carried to the esophageal opening of the diaphragm. Next, the mobilized round ligament of the liver is passed behind the esophagus and its free end is fixed to the left anterolateral surface of the abdominal esophagus to the left of the left vagus nerve. 4–5 sutures are applied, forming the first fixation point. Then, with a portion of the round ligament of the liver, the esophagus is wrapped along the back wall, then along the right side wall of the abdominal esophagus towards its previously fixed free end and fixed at the level of the first fixation point in the same way to the right lateral surface of the abdominal esophagus to the right of the left vagus nerve, forming an open cuff covering the esophagus at 270°.

EFFECT: method allows to increase the efficiency of treatment of gastroesophageal reflux disease in obese patients after longitudinal resection of the stomach, creates a mechanism for fixing the gastric sleeve in the abdominal cavity preventing its migration to the mediastinum, and allows to restore the quality of life and the patient's performance.
