METHOD OF ENTERO-DUODENAL ANASTOMOSIS FORMATION AFTER GASTRECTOMY Russian patent published in 2020 - IPC A61B17/04 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to oncology, and can be used to form duodenum duodenal anastomosis. When duodenum-duodenal anastomosis is formed, the oesophagus-divergent bowel loop is twice at 0.5 cm from the oesophageal-intestinal anastomosis, and is incised with an apparatus UKL-60 to form tantalum sutures. Then intestine is crossed between sutures. Proximal end of the intestinal loop escaping from the oesophageal-intestinal anastomosis is connected to the duodenal stump. First row of nodular seroserous silicone sutures is set aside 0.8 cm from the tantalum sutures. Then 5-7 mm of tantalum sutures are gradually cut off from both ends of anastomosed intestines. Also, 1-2 oblique catgut sutures are staged step-by-step; the posterior lip of the anastomosis is formed by the above algorithm. Further, an anterior lip of the anastomosis is formed, with a submerged ligament suture or a Connell suture, and an anastomosis is completed by superimposing seroserous sutures on a front lip.

EFFECT: method provides prevention of inconsistency of sutures of anastomosis due to staged cutting of tantalum sutures.
