Investigation of the variation of vessels around the pancreatic head based on the first jejunal vein anatomy at pancreaticoduodenectomy.
Article in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
purposePancreaticoduodenectomy (PD) for pancreatic cancer carries a high risk of massive intraoperative blood loss. The artery first approach (AFA) prevents blood loss during PD, but the optimal approach is unclear. The first jejunal vein (FJV) often comprises multiple veins and broadly supports venous drainage of the proximal jejunum. Its ligation carries a risk of proximal jejunum congestion. Here we investigated the anatomical characteristics of PD-associated vessels and AFA approach selection based on FJV anatomy.
methodsThis study included 148 Japanese living donors for liver transplantation. We reviewed their computed tomography images and assessed the anatomical pattern of PD-associated vessels in terms of FJV anatomy.
resultsThe FJV traveled posterior to the superior mesenteric artery in 128 patients (86.5%, dorsal group) and anterior in 20 (13.5%, ventral group). The predominant draining vein of the inferior pancreaticoduodenal vein was the superior mesenteric vein in the ventral group (87.5%) and the FJV in the dorsal group (97.9%). Compared with the dorsal group, the ventral group had a significantly greater percentage with the superior mesenteric vein ventral to the superior mesenteric artery (30.0% versus 10.9%) and a significantly larger posterior superior pancreaticoduodenal vein diameter (3.2 ± 0.9 versus 2.7 ± 0.6 mm, p = 0.0029). These results were validated in patients with pancreatic head cancer.
conclusionsThe anatomical characteristics of PD-associated vessels differed significantly between groups defined by FJV anatomy. Understanding the venous anatomy, especially the FJV, could support selection of the best approach in AFA for PD.
