[Direct transfistulous ultrasound in minimally invasive surgical treatment of infected pancreatic necrosis]. / Pryamoe chresfistul'noe ul'trazvukovoe issledovanie pri minimal'no invazivnom khirurgicheskom lechenii patsientov s infitsirovannym pankreonekrozom.

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.

[A modified method for percutaneous drainage of acute necrotic collections in patients with infected pancreatic necrosis]. / Modifitsirovannyi metod chreskozhnogo drenirovaniya ostrykh nekroticheskikh skoplenii u patsientov s infitsirovannym pankreonekrozom.

OBJECTIVE: To develop a modified method for percutaneous drainage of acute necrotic collections in patients with infected pancreatic necrosis. MATERIALS AND METHODS: Minimally invasive surgical technologies were used in 74 patients with infected acute necrotic collections at the Krasnodar Regional Clinical Hospital No. 2 between 2017 and 2019. Of these, 59 (79.7%) people underwent percutaneous drainage as a final treatment. In 11 (14.9%) patients, video sequestrectomy through the fistula was additionally used to increase efficiency of percutaneous drainage. RESULTS: PCD in our modification implies delivery of double-lumen drains 26-32 Fr in the same plane to zones of necrosis, their programmed replacement for prevention of obstruction and flexible endoscopy for control of pathological process. Local purulent-necrotic parapancreatitis occurred in 31 (41.9%) patients, widespread parapancreatitis - in 43 (58.1%) patients. There were 339 minimally invasive interventions. Laparotomy was required in 4 (5.4%) patients. Incidence of perioperative complications was 10.6%, mortality - 16.2%. CONCLUSION: A modified percutaneous drainage method may be used as final surgical treatment in 79.7% of patients with infected pancreatic necrosis.

[Technological features of open and minimally invasive surgical treatment of local complications of purulent-necrotic pancreatitis]. / Sravnenie tekhnologicheskikh osobennostei primeneniya otkrytykh i minimal'no invazivnykh sposobov khirurgicheskogo lecheniya mestnykh oslozhnenii gnoino-nekroticheskogo pankreatita.

There are various options for surgical treatment of purulent-necrotic pancreatitis with significant technological differences. Combining surgical methods other than traditional ones into a group of minimally invasive ones based on the principle of the absence of standard laparotomy is not entirely correct. The review presents modern methods of surgical treatment of acute pancreatitis, comparison of their technology regarding classical stages of surgical intervention and their classification.
