[Direct transfistulous ultrasound in minimally invasive surgical treatment of infected pancreatic necrosis].

OBJECTIVE

To develop a method for direct transfistulous ultrasound in minimally invasive treatment of infected pancreatic necrosis.

MATERIAL AND

METHODS

There were 148 patients with infected pancreatic necrosis between 2015 and 2019 at the Krasnodar City Clinical Hospital No. 2. Drainage with 28-32 Fr tubes was carried out at the first stage, endoscopic transfistulous sequestrectomy - at the second stage (19 (12.8%) patients). In 84 (56.8%) patients, we applied original diagnostic method (transfistulous ultrasonic assessment of inflammatory focus).

RESULTS

There were 3 accesses to omental bursa in 93 (62.8%) patients and 2 in 43 (29.1%) patients. We also performed 2 access to retroperitoneal space in 63 (42.6%) patients and 1 access in 38 (25.8%) cases. Transfistulous ultrasound was used once in 19 (22.6%) patients, twice in 28 (33.3%) and 3 times in 37 (44.1%) patients. Examination was not performed in 18 (12.2%) patients due to the following reasons: migration of drainage catheters - 5, non-rectilinear fistulous tract - 13. No complications were observed.

CONCLUSION

Transfistulous ultrasound makes it possible to diagnose pathological changes in the pancreas and parapancreatic tissue at various stages of surgical treatment.
