Early vs. late percutaneous catheter drainage of acute necrotic collections in patients with necrotizing pancreatitis

摘要

Purpose It is recommended to drain the pancreatic fluid collections later in the course of the acute necrotizing pancreatitis (ANP). However, earlier drainage may be indicated. We compared early (<= 2 weeks) vs. late (3rd to 4th week) percutaneous catheter drainage (PCD) of acute necrotic collections (ANC).Materials and methods This retrospective study comprised ANP patients who underwent PCD of ANC. The diagnosis of ANP was based on revised Atlanta classification criteria and computed tomography performed between 5 and 7 days of illness. Patients were divided into two groups 1st 2 weeks (group I) and 3rd-4th weeks (group II) based on the interval between the onset of pain and insertion of catheter. The technical success, clinical success, complications, and clinical outcomes were compared between the two groups.Results One hundred forty-eight patients (74 in each group) were evaluated. The procedures were technically successful in all patients. The clinical success rate was 67.6 in group I vs. 77 in group II (p = 0.069). The incidence of complications was significantly higher in group I (n = 12, 16) than group II (n = 4, 5.4) (p = 0.034). These included 15 minor (11 in group I and 4 in group II) and one major complication (group I). Of the clinical outcomes, the need for surgery was significantly higher in group I than in group II (13 patients vs. 5 patients, p = 0.031).Conclusion Early PCD is as technically successful as late PCD in the management of ANC. However, early PCD is associated with higher surgical rate and higher incidence of complications.
