The customized therapeutic approach of a giant pancreatic pseudocyst. A case report and literature review

Abstract

Giant pancreatic pseudocysts are considered those cysts whose dimensions exceed 10 cm and are sporadically reported in the literature. Although there are multiple treatment modalities, there are currently no treatment guidelines or consensus on the best therapeutic approach for giant pancreatic pseudocysts. We report the case of a 32-year-old male patient with a giant pancreatic pseudocyst after an episode of acute pancreatitis, which was treated by internal surgical drainage through cyst-jejunal anastomosis. This surgical procedure was followed by the formation of a retroperitoneal abscess which was resolved by ultrasoundguided drainage. The subsequent evolution of the patient was favorable, without other complications. Given their complex anatomical relations, the treatment of giant pseudocysts requires strategies adapted to the local conditions. The optimal choice of the operative time and of the therapeutic strategy is based on clinical considerations and the effectiveness of the method used can be assessed by a long-term follow-up.
