Abstract
For successful one-stage operation of obstructive left colorectal cancer, the method of inserting a decompression tube through the obstructive lesion using a colonoscope was tried.
The decompression tube was inserted beyond the obstructive lesion through the guide-wire after confirming the lesion in colonoscopy. This method was applied to 7 cases, resulting in 4 successes and 3 failures. Successful cases were two sigmoid colon cancers, one descending colon cancer, one recurrent sigmoid colon cancer. One-stage operations were performed after preoperative examinations and adequate colon preparation with intravenous hyperalimentation. If possible, one-stage operation after conservative decompression is desirable for the cases of obstructive colorectal cancers. In cases of the obstructive left colorectal cancers, the method of inserting a decompression tube using a colonoscope was effective.
