Right colon has complicated anatomy which is surrounded by important organs. The variations of vessels are more frequent than in left colon, which contribute to the difficulty of surgery. Among the variations, Henle's trunk is more obvious that makes it the commonest cause of bleeding during operation. Several veins can be found to conjoin the Henle's trunk, among which ASPDV and REGV are the two common tributaries while RCV,MCV,SRCV may vary from people to people. As a result, a better understanding of the anatomical classification of Henle's trunk is a must during operation. However, existing studies of Henle's trunk are very rare and often single-centered with minimal samples.In order to achieve better surgical outcome and reduce operative complications, the investigators design this study to investigate the anatomical classification of Henle's trunk and the surgical outcome of each type.
Full Title of Study: “Multicenter Clinical Trial of Anatomical Classifications of Henle’s Trunk in Laparoscopic Right Hemi-colectomy.”
- Study Type: Observational
- Study Design
- Time Perspective: Prospective
- Study Primary Completion Date: May 17, 2019
Clinical Trial Outcome Measures
- classifications of Henle’s trunk
- Time Frame: 2 yeas
- based on the number of colic veins that conjoin the SMV
Participating in This Clinical Trial
1. Patients who undergoing laparoscopic right hemi-colectomy with D3 lymphadenectomy 2. Pathology: adenocarcinoma or high-grade intraepithelial neoplasia proven by colonoscopic biopsy. 3. Localization: tumor located between cecum and proximal 1/3 portion of transverse colon. 4. Patients have to be aware of the aim of the trial, and have signed the informed consent. Exclusion Criteria:
