Laparoscopic total gastrectomy for advanced gastric cancer with anomalous splenic vein and hepatic artery: a case report.
Article in BMC surgery, 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
backgroundSurgery for gastric cancer involves gastrectomy with lymph node dissection based on established arterial landmarks. While arterial variations around the celiac axis are well recognized, venous anomalies such as aberrant courses of the splenic vein have received limited attention, and their potential impact on the safety of standard lymphadenectomy remains unclear. We report a case of laparoscopic total gastrectomy complicated by an aberrant course of the splenic vein that posed a potential risk of vascular injury during standard lymph node dissection. CASE PRESENTATION: An 80-year-old man with type 3 advanced gastric cancer of the lesser curvature of the gastric body was referred for surgery. Contrast-enhanced computed tomography could not be performed because of chronic renal dysfunction, limiting preoperative vascular assessment. Intraoperatively, an aberrant common hepatic artery arising from the superior mesenteric artery and a left hepatic artery branching from the left gastric artery were identified. In addition, the splenic vein coursed ventrally to the celiac artery and was located within the standard lymphadenectomy plane, posing a potential risk of venous injury during standard dissection. Laparoscopic total gastrectomy with D2 lymph node dissection was successfully completed with careful dissection and splenic vein taping, without intraoperative complications.
conclusionsEven during standard lymphadenectomy based on arterial landmarks, aberrant courses of the splenic vein may increase the risk of vascular injury, particularly when preoperative imaging is limited. Awareness of potentially hazardous venous anatomy, in addition to arterial variations, is essential for safe laparoscopic gastrectomy.
