TREATMENT OF INFECTED PANCREATIC NECROSIS BY MINIMALLY INVASIVE INTERVENTIONS

A simple comparative multicenter study included 270 patients with infected pancreatic necrosis who were treated for the period from 2016 to 2023. Paients were divided into three groups: 1 group – 90 patients who underwent only remedial laparotomy. 2 group – 90 patients who had minimally invasive drainage as the first stage followed by subsequent remedial laparotomy. 3 group – 90 patients with only minimally invasive drainage. Patients distribution by age, comorbidities, severity of purulent necrotic parapancreatitis and therapeutic medical complex was homogeneous. There were maximal incidence of complications (digestive fistula, bleeding, RDS, severe sepsis) and mortality rate in group 1. In group 2 there was a tendency to decrease of morbidity and mortality in infected pancreatic necrosis patients although their level remained high. Minimally invasive interventions (3 group) for infected pancreatic necrosis resulted significant reduction of morbidity and mortality. Minimally invasive techniques should be preferred for primary drainage of infected pancreatic necrosis (purulent necrotic parapancreatitis). Laparotomy with necrosectomy is necessary in case of ineffectiveness of minimally invasive drainage or appearance of complications that can not be treated using minimally invasive interventions.
