Description
Summary:	Purpose To compare the success rate, clinical outcomes, and complications of retroperitoneal (RP) versus transperitoneal (TP) percutaneous catheter drainage (PCD) of the necrotic pancreatic fluid collections. Materials and methods This retrospective study comprised consecutive patients with acute pancreatitis who underwent PCD of lesser sac collections amenable to drainage via both TP and RP routes. The patients were divided into two groups based on the route of drainage (group I, RP, and group II, TP). The technical success, clinical success, complications, and clinical outcomes were compared between the groups. Subgroup analysis was performed based on the timing of drainage (acute necrotic collections, ANC vs. walled-off necrosis, WON) and organ failure (OF). Results Seventy-nine patients [mean age, 38.7 ± 12.3 years, 54 males] were included in the study. Group I and II comprised 22 (27.8%) and 57 (72.2%) patients, respectively. The procedures were technically successful in all the patients. There was no significant difference in the complication rate between the two groups. The clinical success was higher in group II (75.4%) as compared to group I (54.5%). However, the difference was not statistically significant (p = 0.070). There was no significant difference in the hospital stay ( p = 0.298), intensive care unit stay ( p = 0.401), need for surgical necrosectomy ( p = 0.243), and mortality ( p = 0.112) between the two groups. The outcomes in patients with OF and ANC were not affected by the route of PCD. Clinical success rate was significantly higher in WON undergoing TP drainage ( p = 0.009). Conclusion Both RP and TP routes of PCD are safe and effective. Clinical success rate was significantly higher in WON undergoing TP drainage. Graphical abstract
