Background and study aims: Motorized spiral enteroscopy is proven to be effective in antegrade and retrograde enteroscopy. Nevertheless, little is known about its use in less common indications. The aim of this study was to identify new indications for the motorized spiral enteroscope.
Methods: Monocentric retrospective analysis of 115 patients who underwent enteroscopy using PSF-1 motorized spiral enteroscope between January 2020 and December 2022.
Results: A total of 115 patients underwent PSF-1 enteroscopy. 44 (38%) were antegrade procedures and 24 (21%) were retrograde procedures in patients with normal gastrointestinal anatomy with conventional enteroscopy indications. The remaining 47 (41%) patients underwent PSF-1 procedures for secondary less conventional indications: n=25 (22%) enteroscopy-assisted ERCP, n=8 (7%) endoscopy of the excluded stomach after Roux-en-Y gastric bypass, n=7 (6%) retrograde enteroscopy after previous incomplete conventional colonoscopy and n=7 (6%) antegrade panenteroscopy of the entire small bowel. In this group of secondary indications, technical success rate was significantly lower (72.5%) as compared to technical success rates in the conventional groups (98-100%, p<0.001 Chi-square). Minor adverse events occurred in 17/115 patients (15%), all treated conservatively (AGREE I and II).
Conclusion: This study demonstrates the capabilities of PSF-1 motorized spiral enteroscope for secondary indications. PSF-1 is useful to complete colonoscopy in case of long redundant colon, to reach the excluded stomach after Roux-en-Y gastric bypass, to perform unidirectional pan-enteroscopy and to perform ERCP in patients with surgically altered anatomy. However, technical success rates are lower as compared to conventional antegrade and retrograde enteroscopy procedures, with only minor adverse events.
