METHOD FOR SURGICAL TREATMENT OF SUPEROBESITY AND GASTROESOPHAGEAL REFLUX DISEASE Russian patent published in 2022 - IPC A61B17/00 A61B17/68 A61M25/01 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to abdominal surgery, gastroenterology. Patients with a body mass index (BMI) greater than or equal to 60 kg/m² before surgery are subjected to fluoroscopy of the stomach with barium suspension and endoscopic ultrasound, revealing signs of pylorospasm and hypertrophy of the pyloric sphincter. The stomach is mobilized along the greater curvature, starting 2 cm above the pyloric sphincter to the angle of His with mobilization of the left leg of the diaphragm and the left semicircle of the esophagus. The zone of pyloric sphincter is visualized. A pylorotomy is performed for 2 cm, the serous and muscle fibers of the pyloric region are dissected to the submucosal layer. The pylorotomy opening is sutured with a continuous gray-serous gastroduodenal endosuture and additionally covered with the anterior wall of the antrum of the stomach. Then, a 36 Fr probe is passed into the stomach and duodenum, on which a longitudinal resection is performed along the greater curvature of the stomach with a linear stapler.

EFFECT: method allows to achieve a stable reduction and prevention of body weight gain in patients with overweight (BMI ≥60 kg/m²) in combination with gastroesophageal reflux disease (GERD) and, as a result, reduce the effects of reflux esophagitis, reduce trauma and shorten the time of surgery, reduce the risk of postoperative complications in the early and late postoperative periods.
