Necrosectomy in the Management of Necrotizing Pancreatitis

Recent Treatment Strategies for Acute Pancreatitis

Acute pancreatitis (AP) is a leading gastrointestinal disease that causes hospitalization. Initial management in the first 72 h after the diagnosis of AP is pivotal, which can influence the clinical outcomes of the disease. Initial management, including assessment of disease severity, fluid resuscitation, pain control, nutritional support, antibiotic use, and endoscopic retrograde cholangiopancreatography (ERCP) in gallstone pancreatitis, plays a fundamental role in AP treatment. Recent updates for fluid resuscitation, including treatment goals, the type, rate, volume, and duration, have triggered a paradigm shift from aggressive hydration with normal saline to goal-directed and non-aggressive hydration with lactated Ringer's solution. Evidence of the clinical benefit of early enteral feeding is becoming definitive. The routine use of prophylactic antibiotics is generally limited, and the procalcitonin-based algorithm of antibiotic use has recently been investigated to distinguish between inflammation and infection in patients with AP. Although urgent ERCP (within 24 h) should be performed for patients with gallstone pancreatitis and cholangitis, urgent ERCP is not indicated in patients without cholangitis. The management approach for patients with local complications of AP, particularly those with infected necrotizing pancreatitis, is discussed in detail, including indications, timing, anatomical considerations, and selection of intervention methods. Furthermore, convalescent treatment, including cholecystectomy in gallstone pancreatitis, lipid-lowering medications in hypertriglyceridemia-induced AP, and alcohol intervention in alcoholic pancreatitis, is also important for improving the prognosis and preventing recurrence in patients with AP. This review focuses on recent updates on the initial and convalescent management strategies for AP.

Percutaneous Endoscopic Necrosectomy-A Review of the Literature

In this article, an attempt was made to clarify the role of percutaneous endoscopic necrosectomy (PEN) in the interventional treatment of pancreatic necrosis. A comprehensive review of the current literature was performed to identify publications on the role of PEN in patients with consequences of acute necrotizng pancreatitis. The aim of the study was to review the literature on minimal invasive necrosectomy, with emphasis on PEN using esophageal self-expanding metal stents (SEMS). The described results come from 15 studies after a review of the current literature. The study group comprised 52 patients (36 men and 16 women; mean age, 50.87 (13-75) years) with walled-off pancreatic necrosis, in whom PEN using a self-expandable esophageal stent had been performed. PEN was successfully completed in all 52 patients (100%). PEN complications were observed in 18/52 (34.62%) patients. Clinical success was achieved in 42/52 (80.77%) patients, with follow-up continuing for an average of 136 (14-557) days. In conclusion, the PEN technique is potentially effective, with an acceptable rate of complications and may be implemented with good clinical results in patients with pancreatic necrosis.
