Frequencies and Injury Analysis of Small Anterior Branch of Gastrocolic Trunk.

Objective: Small anterior branch of gastrocolic trunk (SABGT) can be occasionally observed during transverse colectomy and right hemicolectomy. Improperly dealing with the branch may lead to unwanted bleeding and affect the operation process. The purposes of this study are to analyze the frequencies and injury of SABGT. Methods: Intact operation data were collected retrospectively from 39 colon cancer patients who underwent curative laparoscopic transverse colectomy or right hemicolectomy. Frequencies and injury of SABGT were analyzed. Results: Eight cases had SABGT, the frequencies of which is 20.5%. Injury of SABGT occurred intraoperatively in 2 patients. Conclusion: We suggest that SABGT should be considered in surgical management. Consciously looking for and properly dealing with the branch can minimize the influence on the operation process.
