New clip for colonoscopy prevents bowel surgery
Colonoscopy (colonoscopy) is the most important and meaningful examination for the early detection and diagnosis of colon cancer. If polyps are removed, injuries can sometimes occur. There has been a new therapeutic option for their treatment for several years.
Most important examination for the early detection of colon cancer
According to the German Cancer Society, colonoscopy (colonoscopy) is the most important and most meaningful examination for the early detection and diagnosis of colon cancer. According to experts, it can prevent thousands of deaths. Colonoscopy can be used to remove benign changes that may later lead to malignant tumors. But sometimes the intestinal wall is injured. There is a new therapeutic option for treating these injuries.
Sometimes the intestinal wall is injured
Removing polyps (benign growths in the intestine) during a colonoscopy can rarely damage the intestinal wall.
As the Techniker Krankenkasse (TK) reports in a message, a special attachment has been used on the endoscope for four years to treat such tissue damage.
But is this method really safe and effective?
Due to the small number of cases, there is little information available on this question. An evaluation of TK data now supports initial assessments, according to which the innovative process with the so-called "OTS clip" is safe.
According to the information, operations can be avoided in certain cases.
New therapeutic option
"Our evaluation shows that routine data can help assess the benefits and safety of medical technology innovations," says Dr. Dirk Horenkamp-Sunday from TK.
According to the health insurance company, an average of 30 to 50 percent of patients with colonoscopy are found to have polyps in the intestinal wall. To prevent them from developing colon cancer, they are removed during the examination.
If tissue damage to the intestinal wall (bleeding or small holes) occurs, there has been a new therapeutic option since 2015.
With a larger clip that is mounted on the inspection camera, the endoscope, more tissue and deeper parts of the wall can be gripped than was previously possible.
Like a freezer bag that is closed with a clip, this clip can grip and pull holes in the intestinal wall. The essay is called an OTS clip (Over The Scope Clip).
Operations can be avoided
Since there has been little data from highly specialized centers for interventions with the new instrument on the large intestine so far, TK has initiated a cooperation project with gastroenterologist Professor Herbert Koop from Berlin.
Thanks to the integration of clinical expertise, 500 cases were identified from pseudonymized routine data from around ten million TK insured persons, in which the OTS clip was used between 2015 and 2018.
The OTS clip is mainly used in connection with the removal of polyps. It is also used after accidental injuries to the intestinal wall, for example in the context of a colonoscopy.
"The data indicate that the use of the clip is safe and that operations could be avoided especially after injuries to the intestinal wall," explains Horenkamp-Sonntag.
In the first ten or one hundred days after clipping, the 311 patients who had bowel polyps removed only required an abdominal surgery in 1.3 percent of the cases and 8.7 percent of the cases, respectively.
With the previous approach, the operation rate would have been significantly higher. (ad)
