FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to minimally invasive surgery, gastroenterology. Percutaneous punctures of the cavity of the omental bursa are performed through the gastrocolic ligament and paracolon on the right and left by extraperitoneal access, followed by passing through the needles of 2-3 rigid conductors into the cavity of the omental bursa and 1-2 into the retroperitoneal space. The conductors produce bougienage of puncture channels. Tubular drains are introduced into the channels. After 5-6 days, rigid pipes are inserted through the drains, drains are removed, and a convex high-frequency sensor is sequentially inserted through the pipes and ultrasound scanning of the pancreas and parapancreatic fat is performed. After 10-12 days, during the formation of channels, the drains are removed, a sensor without a pipe is inserted through the channels, an ultrasound scan of the results of the state of the pancreas and parapancreatic tissue is performed, after which the drains are re-installed.

EFFECT: method provides the possibility of introducing a convex high-frequency probe with a diameter of 10 mm, visualizing the structure, contours of the pancreas, diagnosing abscesses in the pancreas and parapancreatic tissue of small sizes that are not determined by other methods for instrumental diagnostics, visualizing sequesters, their sizes, including in dynamics for evaluation the effectiveness of the treatment, determining the ratio of the position of necrosis (sequester) and large vessels to predict the risk of bleeding during necrosequestrectomy, as well as assessing the state and effectiveness of stopping the purulent-necrotic process in the omental bag.
