If the polyp is in a tricky location, such as a fold of the colon, the surgeon can gently undo the fold temporarily. If the polyp is large and deeply embedded, the surgeon can monitor the outside of the colon with a tiny camera and, if needed, perform minor wall repair to the colon after the polyp is removed.
Once the polyp is removed, it is immediately taken to the lab for analysis to determine if it's benign or cancerous, while the team and patient wait in the operating room. The analysis takes about 30 minutes. If the polyp turns out to be cancerous, the team proceeds with the standard surgery to remove the affected portion of the colon.
According to the UCLA report, all polyps were successfully removed with the new CELS procedure, and the complication rate was lower than with standard surgery. Four out of the five patients who had the CELS procedure, and six out of nine patients who received standard surgery, were found to have benign polyps.
The procedure time and hospital stay were shorter with the new procedure, the researchers found. Operating time averaged 159 minutes, compared with 205 minutes for standard surgery, and the median hospital stay was one night with the new procedure and five nights with standard surgery.
"The majority of patients in the study had a benign polyp," Yoo said. "We found that the new procedure can be performed safely with outcomes that compare favorably with standard surgery for these select patients."
In the majority of the CELS cases, findings from the quick lab analysis were accurate. However, one patient's final pathology report, which came back a week later, showed that the polyp was cancerous, so that patient was scheduled
