Minimally Invasive Right Colectomy Anastomosis Study

Right colectomy (hemicolectomy) involves the removal of the cecum, the ascending colon, the hepatic flexure, the first one-third of the transverse colon, part of the terminal ileum, and the associated regional fat and lymph nodes, and is the accepted treatment for malignant neoplasms of the right colon.

A minimally invasive approach is commonly used for right colectomy, with studies reporting reduced complications, less blood loss, and hospital stay when compared to an open approach.

However, there remains controversy regarding whether robotic assistance is advantageous for this technique and whether an intracorporeal (ICA) or extracorporeal anastomosis (ECA) is best.

MIRCAST is a prospective, observational, international, multi-center, 4-parallel-cohorts study. Sites or surgeons will select a cohort of the study for which they are qualified. Four cohorts will be the subject of study:

1. Robotic Right Colectomy with ICA

2. Robotic Right Colectomy with ECA

3. Laparoscopic Right Colectomy with ICA

4. Laparoscopic Right Colectomy with ECA

All patient assessments will be done according to the sites standard of care. Parameters routinely recorded during right colectomy surgery will be collected prospectively. Enrolled subjects will undergo assessments at the following intervals: pre-operative, operative, discharge, 30 days, 3 months, 1 year and 2 years post-surgery.
