METHOD FOR FORMATION OF OESOPHAGOGASTROANASTOMOSIS AFTER MINIMALLY INVASIVE VIDEO-ASSISTED THORACOLAPAROSCOPIC RESECTION OF OESOPHAGUS OF LEWIS TYPE Russian patent published in 2025 - IPC A61B17/11 A61B17/94 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to oncology, surgery, gastroenterology, and can be used in oesophageal resections with single-stage plasty and formation of oesophagogastroanastomosis by thoracoscopic approach. Oesophagus is transected in layers. Apex of the gastric transplant and the oesophagus are fixed by two sutures along its lateral walls. Graft wall is dissected in the transverse direction according to the width of the oesophagus lumen. Two traction sutures are formed through the angles of the dissected wall of the stomach and lateral walls of the oesophagus and brought out to the chest wall at the level of the anastomosis along the scapular line and along the anterior axillary line. Posterior lip of the anastomosis is formed with two or three interrupted sutures through all layers of the oesophagus and the graft. Anterior lip of the anastomosis is formed starting from the anterior angle with immersion of the traction sutures at the angles of the anastomosis into the lumen. Hand suture line of the anterior lip of the anastomosis or anastomosis is covered with a strand of a greater omentum in a circular manner.

EFFECT: method is technically simple, reproducible, provides a reduction in the time of forming the anastomosis, the possibility of forming all stages of the anastomosis under complete visual control, reduces risk of developing anastomosis leakage, does not require stapling-cutting devices and additional thoracoscopic ports with minimum suture material.
