Incidentally discovered duplicated cystic duct during open pancreaticoduodenectomy: a case report.
Article in Journal of surgical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
True duplication of the cystic duct draining a single gallbladder is an exceptionally rare biliary anomaly, with fewer than 40 cases reported in the English literature. Failure to recognize this variant during complex hepatobiliary surgery carries significant risk of bile duct injury. We report a 60-year-old male undergoing open pancreaticoduodenectomy for pancreatic adenocarcinoma in whom an H-type duplicated cystic duct was incidentally identified during dissection of Calot's triangle. Both ducts were individually clipped and divided; ductoplasty was performed to facilitate biliary reconstruction. The procedure was completed without biliary complications. A systematic PubMed and Scopus search confirmed this as the first reported case of duplicated cystic duct encountered during pancreaticoduodenectomy, extending the spectrum of surgical contexts beyond cholecystectomy and hepatic resection. This case underscores the importance of meticulous dissection and heightened anatomical vigilance in pancreatic oncologic surgery.
