CASE REPORT Management of a Complicated Pancreatic Pseudocyst: Report of a Case and Review of the Literature Apostolos Αngelis, Stylianos Kykalos, Zoe Garoufalia, Elli Karatza, Nikolaos Garmpis, Christos Damaskos, Theodore Karatzas Second Department of Propedeutic Surgery, Laiko General Hospital, Medical School, National and Kapodistrian University of Athens, Greece ABSTRACT Case report Herein we present a case of a huge complicated pancreatic pseudocyst following an episode of acute necrotizing pancreatitis, the treatment approaches and a short review of the literature. Methods An on-line survey in PubMed was conducted using the terms the patient regarding his treatment. Results Treatment of a pancreatic pseudocyst is a challenging process requiring a close follow-up of the“acute patient pancreatitis-complications”, and a fully equipped institution “pancreatic with pseudocyst” medical team and ready “pancreatic to cope against pseudocyst any possible treatment”. complications We also used of the the different data from therapeutic the file of interventions including open surgery. Conclusion Pancreatic pseudocyst is a complication of acute or chronic pancreatitis which should be managed closely for a longstanding period and treated effectively by endoscopic and surgical means, either alone or in combination, so that the outcome of this complication to be in favor of the patient.
