GASTRO-OESOPHAGEAL ANASTOMOSIS FORMATION METHOD Russian patent published in 2024 - IPC A61B17/11 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to abdominal surgery, gastroenterology, oncology, and can be used in treating diseases of oesophagus and cardiac stomach requiring resection with creation of oesophagogastroanastomosis. Between the posterior wall of the oesophagus stump from its centre and the anterior wall of the stomach, below the proximal edge of its remnant, a continuous blanket serous-adventitial-muscular-submucosal suture with two needles is applied. Monofilament suture is delivered under the last stitch from the left and right edges of the oesophagus, tied and taken on holders. Anterior wall of the stomach is incised below the serous-adventitial-muscular-submucosal suture so that the formed opening of the stomach corresponds to the size of the opening of the oesophagus and forming a precision suture with an absorbable monofilament suture 3/0 with two needles, continuing the suture between the submucosal layers of the oesophagus and stomach with a pricked out edge of the gastric mucosa. Inner row of sutures is invaginated into stomach by means of semi-purse sutures of its wall with sutures, which are tied with ends of monofilament suture from previous suture. Oesophagus and stomach are stitched with a blanket suture from the edges to the centre of the anastomosis; the last stitches of the suture are pricked out on the wall of the stomach at distance of 4 mm from each other and the anastomosis is completed – the sutures are tied over the oesophagus.

EFFECT: method provides good tightness of oesophagogastroanastomosis, models closure function of cardia, eliminates cicatricial stenosis of anastomosis, reduces development of reflux oesophagitis, provides haemostasis of anastomosis due to formation of sphincter-valve areflux oesophagogastroanastomosis.
