Hemicolectomy
Scheme of the large intestine anatomy:
(1) Ascending colon ( ascending colon )
(2) transverse colon ( transverse colon )
(3) Descending colon ( Colon descendens )
(4) Sigma ( sigmoid colon )
(5) mast or rectum ( rectal ), and Anus .
It lacks the marker for the located in the lower left half of the cecum ( cecum ) with attached appendix ( Appendix ).

A hemicolectomy is the surgical removal of about half of the colon . One distinguishes
-
Left hemicolectomy : removal of the left part of the transverse colon , the descending colon and part of the sigmoid colon with subsequent connection of the transverse colon with the sigmoid colon
- Extended : In the case of carcinomas of the left flexure, additional expansion of the resection borders from the right flexure to the recto- sigmoid junction and removal of the lymphatic drainage area belonging to the inferior mesenteric artery and the media colic artery .
-
Right hemicolectomy : Removal of the ascending colon and the right part of the transverse colon with subsequent connection of the small intestine with the transverse colon. During the operation, the last 10 to 15 centimeters of the small intestine and the appendix are also removed.
- Extended : In carcinomas of the right flexure and the proximal transverse colon, additional removal of the entire greater omentum with the gastrocolic ligament and the dextra gastric artery (dextra gastroepiploic artery) for reasons of possible larger lymph node metastases.
A complete removal of the colon is called a colectomy .
