Abstract
BACKGROUND: Endoscopic transmural drainage is usually not performed for pancreatic necrotic collection (PNC) < 4 weeks after onset of acute necrotizing pancreatitis (ANP) because of lack of encapsulating wall and increased risk of complications. OBJECTIVE: Study safety and efficacy of early (<4 weeks) endoscopic transluminal drainage in patients with symptomatic PNC. METHODS: Retrospective analysis of data base of patients with PNC treated with endoscopic transmural drainage within 4 weeks of onset of ANP (early drainage) was done. The outcomes and complications were compared with patients with PNC who underwent delayed endoscopic drainage (≥4 weeks of onset of ANP). RESULTS: Thirty-four patients (26 males; mean age: 35.9 ± 8.6 years) underwent early and 136 patients (115 males; mean age: 37.9 ± 9.4 years) underwent delayed endoscopic drainage. The PNC was significantly larger (12.3 ± 2.1 cm vs 10.5 ± 2.7 cm, p <0.001) with increased solid component (47.7 ± 8.9% vs 28.3 ± 11.7%, p <0.001) in the early group. Clinical success was achieved in 94% patients in the early group and all patients in the delayed group. Direct endoscopic necrosectomy was performed more frequently in the early group (50% vs 7.4%; p<0.001). There was increased mortality (5.7% vs 0%), need for rescue surgical necrosectomy (5.7% vs 0%), and clinically significant bleeding (20% vs 1.5%, p<0.001) in the early group as compared to the delayed group. CONCLUSION: Early endoscopic drainage of PNC is feasible and seems to be safe as well as effective but is associated with increased risk of complications as compared to delayed drainage.
