Effect of internal pancreatic duct stent on reducing long-term pancreaticojejunostomy stenosis following pancreaticoduodenectomy.
Article in Langenbeck's archives of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundAs survival following PD improved, long-term complications have emerged as an issue in current era. Pancreaticojejunostomy stenosis is the common long-term sequel after PD but rarely addressed. This study aimed to investigate the benefit of pancreatic duct stent in reducing PJ stenosis after PD.
methodsBetween July 2006 and July 2019, patients undergoing PD with follow-up more than 1 year were recruited. Patients were divided into internal stent, external stent, and no stent groups. We reviewed the Computed tomography (CT) to measure the diameter of pancreatic duct and stent migration at 3 months and 1 year after PD. PJ stenosis was defined as pancreatic duct diameter > 3 mm. Perioperative variables were collected for analysis.
resultsTotally, 506 patients were included 349 patients in internal stent group, 84 patients in the external stent, and 73 patients in no stent group. There was no difference in preoperative P-duct size between the IS and ES group (3.39 ± 1.78 mm vs 3.26 ± 1.89 mm, p = 0.481), while the P-duct size was larger in ES group compared to the IS group (3.22 ± 2.44 mm vs. 1.94 ± 2.08 mm, p < 0.001) one year after PD. In the internal stent group, the rate of stent migration was 22.1% at 3 months and 67.9% at 1 year post-operatively. CR-POPF (OR 2.24, p = 0.015) and P-duct stent retention at PJ > 3 months (OR 0.45, p < 0.001) were the independent factors for 1-year PJ stenosis in multivariate analysis.
conclusionRetention of internal pancreatic duct stents at the anastomosis for more than 3 months can reduce post-PD PJ stenosis. Extended retention of internal pancreatic duct stents reduces PJ stenosis, highlighting its critical role in preventing long-term complications.
