  1. CPT – colo-pancreatic trunk; GCT – gastro-colic trunk; GPT – gastro-pancreatic trunk; GPCT gastro-pancreato-colic trunk; ICV – ileocolic vein, MCV – middle colic vein; ASPDV – anterosuperior pancreaticoduodenal vein; RGEV – right gastroepiploic vein; RCV – right colic vein; SRCV – superior right colic vein. To proposed a common terminology for Henle trunk, we grouped all the anatomical variants with a pooled prevalence less than 5.0% in the ‘other’ group of ‘Type VI’. Should be noted that Type I has the highest pooled prevalence, and the Type V the lowest.
