Anatomical observation and clinical significance of the left gastric vein in laparoscopic radical gastrectomy.

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
backgroundThe left gastric vein (LGV) plays an important role in laparoscopic radical gastrectomy (LRG). However, the anatomy of the LGV is complicated with significant variation, and it is often damaged and bleeding during LRG. The purpose of this study was to observe and analyze the anatomic types of the LGV in patients undergoing LRG and to explore its clinical significance.
methodsA total of 217 patients who underwent LRG from June 2016 to December 2020 were included. LGVs were divided into four types according to the relationship between the LGV and peripheral arteries [celiac artery (CA)/common hepatic artery (CHA)/splenic artery (SA)] and the pancreas during LRG. If a LGV was damaged during surgery (resulting in bleeding), it was included in the bleeding group. Non-bleeding groups were included if there was no impairment to the LGV.
resultsA total of four types of LGVs were observed, of which type I was the most prevalent, accounting for 58.8% (n=121). In 21 patients (9.7%), the LGV was injured and hemorrhagic during LRG; and the type IV LGV injury bleeding rate was as high as 41.7% (5/12). Univariate analysis revealed that the extent of lymph node dissection (LND), pathological stage, tumor (T) stage, and type of LGV were significantly associated with LGV injury and hemorrhage (P<0.05). Multivariate analysis showed that enlarged LND, late T stage, late pathological stage, and type IV LGV were independent risk factors for LGV injury hemorrhage.
conclusionsLGVs that run between the CHA (posterior) and the CA into the portal venous system were the most common anatomical type. A LGV that runs between the SA (posterior) and the CA into the portal venous system is easily injured (resulting in bleeding). LGV injury and hemorrhage are affected by a variety of factors, and therefore, careful intraoperative dissection is necessary to avoid damage to the LGV.
