RESUMO
OBJECTIVE: To develop an effective minimally invasive method for the treatment of infected pancreatic necrosis. MATERIAL AND METHODS: There were 168 patients with infected pancreatic necrosis who were treated at the Regional Clinical Hospital No. 2 between 2011 and 2018. Eighty-seven (51.8%) patients underwent primary drainage with large-diameter double-lumen drains 28-32 Fr, and original technique of transfistulous endoscopic sequestrectomy was used. Puncture-drainage interventions with transfistulous endoscopic sequestrectomy were used in 23 (26.4%) patients with local and 64 (73.6%) patients with widespread purulent-necrotic parapancreatitis. RESULTS: Percutaneous channels are accesses to purulent-necrotic cavity and used for transfistulous endoscopic sequestrectomy. This procedure was performed 98 times. Time of primary sanitation in patients with 3 accesses in omental bursa was significantly less compared to 2 accesses (62±4.3 vs. 89±8.2 min, p<0.05). In case of repeated sanitation, time of intervention did not depend on the number of accesses. Incidence of local complications was 9.1%, extra-abdominal complications - 19.4%. Mortality rate was 12.6%. CONCLUSION: Original technique of transfistulous endoscopic sequestrectomy increases efficiency of sanitation of infected parapancreatitis, improves treatment outcomes and reduces mortality to 12.3%.
