When it is recommended
The segment removed is the cecum, the ascending colon and part of the transverse colon. The most common indication is cancer of the right colon or cecum. Large right-sided polyps that can’t be removed endoscopically, chronic right-sided inflammatory disease, and some complicated appendix pathology are other reasons.
How the operation is performed
Laparoscopically where possible. The right colon is mobilised, the right-sided blood vessels (ileocolic and right colic) are divided at their origin along with the lymph nodes, and the specimen is removed.
The remaining ileum (end of small bowel) is joined to the remaining transverse colon. Operating time is typically 2–3 hours.
Recovery
Hospital stay is usually 4–6 days. Return to normal diet within about a week; full recovery over 4–6 weeks.
Bowel habits afterwards
Stools may be slightly looser for a few weeks after right-sided surgery because the right colon normally absorbs water. Most patients return to their pre-surgery pattern within 2–3 months; a high-fibre diet helps.
