Therapeutic Alternatives for the Treatment of Infected Pancreatic Necrosis: An Overview

Although infected pancreatic necrosis can develop as a result of rare conditions involving trauma, surgery, and systemic infection with an uncommon pathogen, it usually occurs as a complication of pancreatitis. Early phase of acute pancreatitis can be either edematous interstitial pancreatitis or necrotizing pancreatitis. The late complications of pancreatitis can be divided into pancreatic pseudocyst due to edematous interstitial pancreatitis or walled-off necrosis due to necrotizing pancreatitis. During any time course of pancreatitis, bacteremia can provoke infection inside or outside the pancreas. The patients with infected pancreatic necrosis may have fever, chills, and abdominal pain as inflammatory symptoms. These specific clinical presentations can differentiate infected pancreatic necrosis from other pancreatic diseases. Herein, I report an atypical case of infected pancreatic necrosis in which abdominal pain, elevation of white blood cell, and fever were not found at the time of admission. Rather, a 10-kg weight loss (from 81 to 71 kg) over 2 months nearly led to a misdiagnosis of pancreatic cancer. The patient was finally diagnosed based on endoscopic ultrasound-guided fine-needle aspiration. This case highlights that awareness of the natural course of pancreatitis and infected pancreatic necrosis is important. In addition, endoscopic ultrasound-guided fine-needle aspiration should be recommended for the diagnosis and treatment of indeterminate pancreatic lesions in selected patients.

Abstract Background and study aims Infection of pancreatic necrosis is a dreaded complication requiring an intervention. Nevertheless, the optimal timing of the first intervention is unclear, and consensus data are sparse. This retrospective two-center study evaluated direct endoscopic necrosectomy using lumen apposing metal stents in case of proven or suspected infected pancreatic necrosis in an early stage of the disease. Patients and methods Forty-nine patients with infected pancreatic necrosis were included. Sequent direct endoscopic necrosectomies after lumen apposing metal stent insertion (LAMS) were performed until the resolution of necrosis. In all patients, the first endoscopic intervention was performed within the first 30 days after first proof of pancreatic necrosis. Primary outcome parameters were inflammatory activity, days spent in the Intensive Care Unit (ICU), and mortality. Results The patient cohort received median 4 necrosectomies (3–5) after a median of 7 days (3–11) after first proof of pancreatic necrosis. Technical and clinical success were achieved in 98.3 % and 87.8 %, respectively; the mortality rate was 8.2 %. The median C-reactive protein level decreased from 241 mg/L (182.9–288.9) before the intervention to a median of 23.3 mg/L (18–60) after therapy. The median time period in the ICU was 5 days (3–9). Conclusions Early endoscopic therapy in the form of direct endoscopic necrosectomy after LAMS placement within the first 30 days after proof of pancreatic necrosis is effective and does not result in poor outcome. Our retrospective data suggest that early intervention before walled-off necrosis is formed is tenable when it is essential due to the patient's clinical deterioration.

Patients with acute pancreatitis (AP) often suffer tough complications, some of which are fatal. The early diagnosis and definite treatment of central nervous system (CNS) complications have not been fully achieved yet, which seriously affects the mortality of severe acute pancreatitis (SAP). We present a case of infected pancreatic necrosis (IPN) in a 62-year Chinese man who developed acute herpes simplex encephalitis (HSE) caused by herpes simplex virus type 1 (HSV-1) after favorable minimally invasive retroperitoneal approaches (MIRAs). The patient was successfully treated with 115 days stayed in our hospital. The MIRAs included image-guided retroperitoneal percutaneous catheter drainage (PCD), nephroscopic pancreatic necrosectomy (NPN), and ultrasonic pneumatic lithotripsy system (UPLS) assisted non-narcotic sinus track necrosectomy (NSN). HSE is relatively rare and potentially life threatening. We attempt to discuss the probable risk factors and how the relatively rare HSE are related to the patients of SAP with latent HSV.
