Postpancreatectomy acute pancreatitis after distal pancreatectomy: tri-institutional international cohort.
Article in BJS open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe International Study Group for Pancreatic Surgery (ISGPS) recently introduced a standardized definition and grading system for postpancreatectomy acute pancreatitis (PPAP), which was validated for pancreatoduodenectomy but not for distal pancreatectomy (DP). This study investigated the incidence and predictors of PPAP following DP and its associated postoperative complications.
methodsPatients who underwent DP for all indications between 2015 and 2022 at three European centres were retrospectively analysed. PPAP was defined according to the ISGPS criteria (postoperative serum hyperamylasaemia (POH), radiological findings) and patient clinical deterioration. Standard univariable and multivariable and receiver operating characteristic (ROC) curve analyses were conducted.
resultsAmong 1192 patients, PPAP occurred in 45 (3.8%): 35 grade B (2.9%) and 10 grade C (0.8%). POH without PPAP occurred in 165 patients (13.8%). Clinical outcomes worsened progressively across patients without POH/PPAP, with POH only, and with PPAP (Clavien-Dindo ≥ IIIa: 17.8%, 21.2%, and 53.3%, respectively; overall P < 0.001). PPAP was associated with higher rates of postoperative complications, including pancreatic fistula (68.9%), delayed gastric emptying (17.8%), and unplanned intensive care unit admission (17.8%). Compared with POH only, PPAP was associated with higher C-reactive protein (CRP) levels on postoperative day (POD) 2 and POD3. Among patients with POH, higher CRP levels on POD3 remained independently associated with PPAP in multivariable analysis (adjusted odds ratio 1.01; P < 0.001), together with multiorgan resection and smoking status. ROC curve analyses supported the discriminatory performance of CRP, particularly on POD3.
conclusionPPAP is a rare but potentially severe complication after DP. Among patients with POH, elevated early postoperative CRP, particularly on POD3, may allow early risk stratification, identifying those at high risk of PPAP who may benefit from targeted mitigation strategies.
