Comparison of endoscopic and radiologic drainage for symptomatic postoperative pancreatic fistula-associated collections after distal pancreatectomy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAfter distal pancreatectomy (DP), symptomatic postoperative pancreatic fistula (POPF)-associated collections are common and lead to readmissions. The choice of drainage modality remains debated. This study compared endoscopic and radiologic drainage as first-line treatment.
methodsThis retrospective, single-center study included patients undergoing DP with or without splenectomy from 2012 to 2024. Patients who underwent DP with a concomitant digestive or vascular procedure or pancreatic anastomosis were excluded. The primary outcome was total hospital stay, defined as the sum of the index hospitalization and readmissions.
resultsAmong 607 patients, 124 (20.4%) had POPF, including 94 (15.5%) with a symptomatic collection. Of these, 25 underwent endoscopic drainage (lumen-apposing metal stent, n = 19; double-pigtail stent, n = 6), 12 underwent radiologic drainage, and 57 received another treatment (medical treatment alone, n = 35; drain tract recanalization, n = 15; surgical reoperation, n = 4; endoscopic sphincterotomy, n = 3). The endoscopic and radiologic drainage groups were comparable, except for collection location adjacent to the pancreatic transection margin (endoscopic: 92% vs radiologic: 50%; p = 0.008). Total hospital stay within 90 days was shorter after endoscopic drainage (19 vs 31 days; p = 0.023), with no deaths within 90 days. The clinical success rate was higher after endoscopic drainage (76% vs 50%; p = 0.15), whereas drainage dysfunction was more frequent after radiologic drainage (17% vs 4%; p = 0.2). Four severe complications occurred: three after endoscopic drainage using a LAMS, including two hemorrhagic complications, and one after radiologic drainage. In univariable analysis, collection location adjacent to the pancreatic transection margin and endoscopic drainage were associated with shorter total hospital stay within 90 days (β = - 17 days; 95% CI - 29 to - 4.2; p = 0.010 and β = - 13 days; 95% CI - 24 to - 1.6; p = 0.026, respectively).
conclusionsAfter DP, first-line endoscopic drainage of symptomatic POPF-associated collections was associated with a shorter total hospital stay and a trend toward a higher clinical success rate but may carry a risk of bleeding.
