SURGICAL METHOD FOR TREATING PATIENTS FOR MECHANICAL JAUNDICE Russian patent published in 2007 - IPC A61B17/11 

FIELD: medicine.

SUBSTANCE: method involves longitudinally dissecting supraduodenal choledochus segment and transversely dissecting anterior duodenal wall. Areflux bicuspid invaginating valve is additionally created from mucosubmucous duodenum layers in the vicinity of anastomosis. Seromuscular duodenum tunic is dissected with incision bordering longitudinally located duodenotomy opening, 12-15 mm far from its edges. Circular area is formed. Seromuscular duodenum tunic is separated from the area and removed exposing its submucous layer as two semilunar areas. Then, 5-7 interrupted sutures passing over the duodenotomy opening boundary are placed on back anastomosis semicircle, with mucosubmucous duodenum layers being captured from its lumen outside and further over the cut seromuscular duodenum tunic boundary and choledochotomy opening boundary with choledochus walls being sutured from outside into its lumen. After having placed the sutures onto the back anastomosis semicircle, the sutures are tied in turn. The 5-7 interrupted sutures are placed and tied in turn in the same way on anterior anastomosis semicircle. Redundant mucosubmucous duodenum layers are invaginated as duplicature into duodenum lumen, forming areflux bicuspid invagination valve. Then, 2-3 seromuscular sutures are placed on anterior anastomosis semicircle in addition.

EFFECT: enhanced effectiveness of treatment; prevented regurgitation complications.
