Anatomy of the right colic vein and pancreaticoduodenal branches: a surgical landmark for laparoscopic complete mesocolic excision of the right colon.

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
purposeKnowledge of mesenteric venous anatomy is important to safely perform laparoscopic complete mesocolic excision (CME) of the right colon. Despite their previously reported diversity, consistent features of the right colonic and pancreatic veins can be discerned. The objective of this study was to evaluate anatomical consistency of the right colic vein (RCV) and the pancreaticoduodenal vein associated with the colic vein (PDV-C).
methodsThis study included 125 consecutive patients undergoing contrast-enhanced multidetector-row CT of the abdomen. Images of 100 of these cases were retrospectively reviewed for the positioning of the colonic, gastric and pancreatic veins associated with the superior mesenteric vein (SMV). RCV were classified as three types: Type-I, running on the ventral aspect of the pancreatic head and draining into the right lateral wall of the SMV; Type-II, running apart from the pancreatic head and directly draining into the SMV; and Type-III, draining into the tributaries of the SMV.
resultsThe RCV was identified in 88% of cases, in which the frequencies of Type-I, -II and -III anatomies were 84.1, 9.1, and 6.8%, respectively. All of the Type-I RCVs formed a common trunk with other veins, including the gastroepiploic vein (93.2%) and the superior RCV (59.5%). The PDV-C joined the RCV in 63.5% of the Type-I cases.
conclusionsAnatomical consistency of the RCV together with the PDV-C is present in the majority of cases. Our findings support the view that the appearance of the veins is a useful landmark for laparoscopic CME of the right colon.
