METHOD FOR PREVENTING REFLUX CHOLANGITIS IN SURGICALLY TREATING MECHANICAL JAUNDICE CASES Russian patent published in 2007 - IPC A61B17/11 

FIELD: medicine.

SUBSTANCE: method involves forming anastomosis between gallbladder bottom and jejunum. Intestine used for creating anastomosis is switched off after Roux-Hertzen. Areflux circular invaginating valve is additionally created from mucosubmucous jejunum layers in the vicinity of cholecystojejunoanastomosis. Seromuscular jejunum tunic is dissected with incision bordering longitudinally located jejunotomy opening, 12-15 mm far from its edges. Area of oval shape is formed. Seromuscular jejunum tunic is separated and removed. Then, 5-7 interrupted sutures passing over the jejunotomy opening boundary are placed on back anastomosis semicircle, with mucosubmucous jejunum layers being captured from its lumen outside and further over the cut seromuscular jejunum tunic boundary and cystotomic opening boundary with gallbladder 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 jejunum layers are invaginated as duplicature into jejunum lumen, forming circular invagination valve. Then, 2-3 seromuscular sutures are placed on anterior anastomosis semicircle in addition.

EFFECT: enhanced effectiveness of treatment; prevented regurgitation complications.
