Computer-assisted colonoscopy performs procedures safely

A team of doctors reporting in this month's American Journal of Gastroenterology shows that computer-assisted colonoscopy is safe and effective.

Unsedated colonoscopy is an uncomfortable procedure for most patients.

Discomfort during colonoscopy is largely related to looping of the colonoscope.

The looping of the colonoscope displaces the colon from its native configuration, and stretches attachments to the mesentery.

A novel computer-assisted colonoscope utilizes a fully articulated, computer-controlled insertion tube.

On manual insertion of the colonoscope, the position and angle of the scope's tip are encoded into a computer algorithm.

As the colonoscope is advanced, the computer directs each successive segment to take the same shape that the tip had at a given insertion depth.

Patient acceptance of this new technique was high
American Journal of Gastroenterology

The insertion tube thus changes its shape at different insertion depths in a ‘follow-the-leader' manner.

Dr Axel Eickhoff and colleagues from Germany conducted a prospective, nonrandomized, unblinded, feasibility clinical study using this novel colonoscopy system.

The team of doctors reported that 3 physicians of varying levels of experience participated in the study.

The doctors assessed 11 consecutive patients, of which 7 were men, and 4 were women.

All patients were between 19 and 80 years of age.

The patients met the inclusion criteria for screening or diagnostic colonoscopy.

The cecum was reached in 10 consecutive patients.

The team reported diverticular disease in 2 cases, and multiple colonic polyps in 2 cases.

The doctors identified no complications or adverse effects at discharge, 48 hours, and 30 days postprocedure.

The team found that both physician satisfaction, and patient acceptance of this new technique were high.

Dr Eickhoff's team commented, “In this limited, first of its kind feasibility study, the computer-assisted colonoscope was shown to perform colonoscopy safely and effectively.”

“The colonoscope's unique design limited loop formation during colonoscopy.”

“Large-scale clinical trials are indicated.”
