[Results of motorized spiral enteroscopy in 83 consecutive patients]

For motorized spiral enteroscopy, only limited data are available. We report about our early experiences with the motorized spiral enteroscopy in a retrospective case series. The present worldwide study reported the results of motorized spiral enteroscopy in 68 patients with small bowel diseases and in 15 patients with ERCP and surgically altered anatomy.

This retrospective single-centre study was performed between 01/2020 and 09/2021 in 83 consecutive patients. Indications were known or suspected small bowel diseases or diseases of the bile or pancreatic duct after surgical altered anatomy with Roux-Y anastomosis.

In 68 patients (38 m/30 f; mean age 66.4 years) with an indication for small bowel enteroscopy, diagnostic and therapeutic yield was 86.8% and 41.2%, respectfully. The average depth of maximum insertion was 279 cm with an average insertion time of 64.3 min. In 13 patients (19.7%), complete panenteroscopy was achieved. In patients without prior abdominal surgery, the rate of complete enteroscopy was 46.2%.In 15 patients (9 m; 6 f; mean age 61.8 years) with surgically altered anatomy and Roux-Y anastomosis (the papilla resp.), the biliodigestive anastomosis could be reached in 60%.In the entire case series, the total complication rate was 15.7%. There were no severe complications, such as perforation or major bleeding.

The present case series shows a high rate of panenteroscopies with a short examination time. To confirm these data, further comparative studies for ERCPs in patients with surgically altered anatomy are necessary.
