METHOD FOR DRAINAGE OF RETROPERITONEAL SPACE IN PURULENT-NECROTIC PARAPANCREATITIS Russian patent published in 2022 - IPC A61B17/94 A61B17/00 A61B8/12 A61M25/01 A61M25/06 A61M25/09 A61M27/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to minimally invasive abdominal surgery. Under ultrasound control, 2-3 percutaneous punctures of the omental sac and the paracolon are performed sequentially on the right and/or left by extraperitoneal access. Rigid conductors are carried through the channels of the needle into the omental sac and retroperitoneal space. The needles are removed and puncture channels are treated with a bougie along the conductors, through which the omental sac and the paracolon on the left and/or right, with the condition of covering the purulent cavity and bringing the ends of the drains to necrosis, are sequentially inserted and the drains are blocked with clamps, excluding spontaneous ejection of exudate. Then, alternately, the clamps are removed and the exudate is evacuated, closed with removable drainage bags. Then, after 2-3 days, the drainage bags are removed and the area of purulent-necrotic parapancreatitis is washed with aqueous solutions of antiseptics. From days 7-10, the condition of the omental sac and retroperitoneal space is monitored once a week using omentobursoscopy and retroperitoneoscopy.

EFFECT: method provides simultaneous drainage of the omental sac and paracolons on the right and left; provides effective relief of the purulent-necrotic process in the omental sac and paracolic tissue, expands the possibilities of surgical techniques for drainage of cavities of varying degrees of complexity and configuration and makes it possible to reduce mortality.
