Summary

To investigate the clinical application value of laparoscopic radical right hemicolectomy using the caudal-to-cranial approach versus the medial-to-lateral approach by prospective randomized controlled clinical study.

Conditions

  • Ascending Colon Cancer
  • Ileocaecal Valve Carcinoma
  • Cancer Flexure Hepatic
  • Adenocarcinoma of Hepatic Flexure (Diagnosis)

Interventions

PROCEDURE

the caudal-to-cranial approach

Cutting the peritoneum along the line between the right mesocolon and retroperitoneum, enter the Toldt's space to dissect the posterior of Superior mesenteric vein and Superior mesenteric artery and their branches, and then finished the D3 dissection from caudal to cranial on both sides of the mesentery along the Superior mesenteric vein. In the end, cut the lateral ligament to mobilize the posterior space of ascending colon. This approach is called the caudal-to-cranial approach.

PROCEDURE

the medial-to-lateral approach

First, the pedicle of ileocolic vessels is identified and the mesocolon is dissected between the pedicle and the periphery of the Superior mesenteric vein to expose the second portion of the duodenum. The ileocolic vessels are then cut at their roots. The ascending mesocolon is separated from the retroperitoneal tissues, duodenum, and pancreatic head up to the hepatocolic ligament cranially. The important detail in this procedure is the wide separation between the pancreatic head and the transverse mesocolon.This approach is the medial-to-lateral(MtL) approach
