- Colon carcinoma of the descending colon
- Endoscopically non-(completely) resectable polyp with evidence of high-grade intraepithelial neoplasia.
- Presence of a tumorous change whose dignity cannot be clearly determined.
- Stenoses of other genesis, e.g., in Crohn's disease
In the present case, it is a clinically T3 carcinoma just below the left flexure without evidence of distant metastasis in the liver or lung. For this reason, indication for left hemicolectomy. The middle colic artery will not be resected due to the patient's advanced age and the tumor's distant location.
