    Abstract:
    PURPOSE: Knowledge 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). METHODS: This 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. RESULTS: The 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. CONCLUSIONS: Anatomical 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.
