RESUMO
INTRODUCTION: Because of major morbidity and mortality after open surgery in acute necrotic pancreatitis, an interest in minimally invasive necrosectomy approaches has increased. We report the results of a recently developed minimally invasive technique that we adopted in 2007. MATERIAL AND METHODS: This article contains a retrospective analysis of cases and description of original retroperitoneoscopic necrosectomy technique. There were eight patients aged 25-58 years, who underwent retroperitoneoscopic pancreatic necrosectomy in the Center of Abdominal Surgery, Vilnius University Hospital Santariskiu Klinikos, between 2007 and 2009. All patients had at least 30% pancreatic necrosis with extensive retroperitoneal fluid collections on the left side, proved by CT scan. Operations were performed on the 21st-56th days of illness (median, 36th day). RESULTS: The mean postoperative hospital stay was 49 days (range, 14-99 days). All patients survived. Two patients underwent three additional procedures; two patients, one additional procedure due to remaining infected necrosis. Three patients had no requirement for additional procedures. One patient underwent laparotomy because of bleeding. CONCLUSIONS: We assume that minimally invasive techniques should be considered a first-choice surgical option in patients with acute necrotic pancreatitis, whenever it is possible. Pancreatic necrosis less than 30% with large fluid collections in the left retroperitoneal space facilitates employment of three-port retroperitoneoscopic necrosectomy.
