Safety and efficacy of early image-guided percutaneous interventions in acute severe necrotizing pancreatitis: A...

Acute necrotizing pancreatitis is managed conservatively in early phase of the disease. Even minimally invasive procedure is preferred after 21 days of onset and there is a paucity of data on decision and outcomes of early radiological interventions. This study aimed to evaluate efficacy and safety of early image-guided percutaneous interventions in management of acute severe necrotizing pancreatitis.

A single-center retrospective study was performed after obtaining Institutional review board approval for analyzing hospital records of patients with acute necrotizing pancreatitis from January 2012 to July 2017. Seventy-eight consecutive patients with necrotizing pancreatitis and acute necrotic collections (ANC) were managed with percutaneous catheter drainage (PCD) and catheter-directed necrosectomy, in early phase of the disease (< 21 days). Clinical data and laboratory parameters of the included patients were evaluated until discharge from hospital, or mortality.

Overall survival rate was 73.1%. Forty-two (53.8%) patients survived with PCD alone, while the remaining 15 (19.2%) survivors needed additional necrosectomy. The timing of intervention from the start of the hospitalization to drainage was 14.3 ± 2.4 days. Significant risk factors for mortality were the presence of organ system failure, need for mechanical ventilation, renal replacement therapy, and the acute physiology and chronic health evaluation II (APACHE II) score. An APACHE II score cutoff value of 15 was a significant discriminant for predicting survival with catheter-directed necrosectomy.

An early PCD of ANC in clinically deteriorating patients with acute necrotizing pancreatitis, along with aggressive catheter-directed necrosectomy can avoid surgical interventions, and improve outcome in a significant proportion of patients with acute necrotizing pancreatitis.
