Lymphatic and vascular anatomy define surgical principles for radical treatment of distal duodenal and proximal jejunal tumors.
Trial report in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to trial NCT05670574 (Surgery With Extended), which is not on this 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.

Abstract
backgroundThe arterial ligation level and the lymphadenectomy extent for surgical treatment of distal duodenal/proximal jejunal tumors are not standardized.
aimTo define morphometric and topographic specifics of the superior jejunal artery (SJA) and the superior jejunal vein (SJV), and the width of arterial lymphovascular bundles through lymphatic clearances. By extrapolating results from two methodologies, the goal is to determine the arterial ligation level and the lymphadenectomy extent for duodenojejunal tumor treatment. MATERIAL AND
methodsThe first series included an analysis of preoperative 3D-CT vascular reconstructions from 97 patients. The second series included 11 dissected cadavers where the course of the proximal mesenteric lymphatics was followed. The SJA was defined as the uppermost jejunal artery (JA) counted from the ileocolic artery (ICA) origin.
resultsSJA proper was present in 72 cases (74.2%). The mean SJA caliber was 3.4 ± 1.2 mm. SJA originated 17.5 ± 16.8 mm cranial to the middle colic artery (MCA) origin and was found cranial to it in 84 cases. SJA originated caudal to the inferior pancreatic border in 80 cases (82.8%) and cranial in 17 (17.2%). SJV coursed anteriorly to the superior mesenteric artery in 29 cases (29.9%). The distances of the cranial and caudal lymphatics following SJA at the level of the arterial origin were 1.15 ± 0.53 mm and 0.6 ± 0.35 mm.
conclusionsTo achieve adequate lymphatic clearance, it is crucial to ligate the tumor-feeding SJA at its origin. The conical arrangement of the SJA lymphatics underscores the necessity of a mesenterectomy extending both cranially and caudally, including lymphadenectomy along the adjacent JA to the level of the first arcade.
