Postoperative Cholangitis After Pancreatoduodenectomy: A Frequent Late Complication Demanding Standardized Prevention and Treatment Protocols.
Article in Annals of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPostoperative cholangitis (POC), a late complication after pancreatoduodenectomy, is thought to be caused by digestive fluid reflux to the biliary tract or an anastomotic stricture. It is not clear which perioperative risk factors contribute to POC.
methodsThis study included all adult patients undergoing pancreatoduodenectomy between 2008 and 2021 at Karolinska University Hospital, Stockholm, Sweden. Electronic medical records were used to identify patients with POC. Fine and Gray and logistic regression models were used to investigate perioperative risk factors for late cholangitis.
resultsOf the 1002 patients in the study, 86 (9%) experienced POC, and 33 (38% of all the patients with POC) had recurrent POC at least three times during the follow-up period. Preoperative biliary drainage (PBD) was associated with a lower risk of POC (unadjusted subhazard ratio [SHR] 0.60; 95% confidence interval [CI] 0.39-0.92). The patients with Clavien-Dindo grade ≥IIIa complications and those with bile leakage grade B or higher had a higher risk of POC (odds ratio [OR] 1.76 [95% CI 1.11-2.81] and OR 2.76 [95% CI 1.19-6.64], respectively). Intermittent antibiotic treatment was used for 78 (91%) of the POC patients, and 36 (42%) of the POC patients were receiving prophylactic treatment. There were no major differences in the risk of cholangitis and surgical technique, including anastomosis level and suture method.
conclusionsPostoperative cholangitis after pancreatoduodenectomy is a rather common late complication, occurring in nearly 1 of 10 patients. In this study, preoperative biliary drainage was associated with a decreased risk of cholangitis. Also, the patients with major postoperative complications, including biliary anastomotic leakage, were more likely to experience cholangitis.
