Usefulness of Dennis Colorectal Tube in endoscopic decompression of acute, malignant colonic obstruction.

Author information

Departments of Gastroenterology and Surgery, Showa Inan General Hospital, Komagane, Japan.



Colonoscopic decompression has been attempted in patients with acute colonic obstruction caused by colon cancer to avoid emergency surgery and multiple subsequent operations but has usually been unsuccessful. This is an evaluation of the usefulness of a new device for endoscopic decompression in these patients.


Nine consecutive patients (6 men, 3 women; 65 to 89 years of age) with acute colonic obstruction resulting from colon cancer underwent endoscopic decompression with a Dennis Colorectal Tube.


In all 9 patients (1 with carcinoma of the sigmoid colon, 3 with carcinoma of descending colon, 2 with carcinoma of the transverse colon, 2 with carcinoma of the ascending colon, and 1 with carcinoma of the cecum), endoscopic decompression was successful. After decompressing and cleansing the colon for several days, a one-stage operation was possible in all patients.


Dennis Colorectal Tube is an excellent device for endoscopic decompression of acute, malignant colonic obstruction.
