Summary

AI Generated

A case series of four patients with previously incomplete colonoscopies due to tortuosity, redundancy, or laxity all achieved successful completion using magnetic balloon technology without adverse events.

All four patients (50-74 years, 3 males, BMI 24.6-37.1) who had prior incomplete sedated colonoscopies completed the procedure with magnetic balloon technology and conscious sedation from February to March 2022
Magnetic balloon technology uses a balloon catheter inserted in the 3.2 mm colonoscope tool channel, filled with ferromagnetic fluid and anchored with an external permanent magnet to facilitate loop solving and colonoscope straightening
Tortuosity, laxity, and/or redundancy were identified in all cases, and magnetic anchorage was achieved in all patients including one with BMI 37.1
No adverse events occurred in this series
The authors conclude that magnetic balloon technology may represent a safe and effective on-demand solution for completing very difficult colonoscopies and preventing rescheduling

Abstract

Introduction

Colonoscopy is not a difficult procedure for most of the colonoscopists. However, some procedures can be challenging even for highly-skilled 4th-level colonoscopists (Kudo’s classification). Magnetic balloon technology was developed to facilitate loop solving and colonoscopy completion.

Aims & Methods

Patients with prior incomplete sedated colonoscopy performed by the author were selected if tortuosity, redundancy or laxity were reported in prior failed colonoscopy. For each patient a colonoscopy with magnetic balloon was rescheduled and performed in the same center (Ospedale San Giuseppe, Empoli, Firenze, Italy) by the same endoscopist (4 th level expert according to Kudo’s classification with completion rate higher than 98%). Complete colonoscope insertion was judged by the colonoscopist if ileocecal valve and the appendiceal orifice could be observed. Magnetic balloon technology includes a balloon catheter that can be inserted on demand in the 3,2 mm colonoscope tool channel, filled with a syringe of ferromagnetic fluid and anchored with an external permanent magnet. The magnetic anchorage is performed to facilitate manoeuvres to solve loops and thus straightening and shortening the colonoscope.

Results

From February to March 2022 a colonoscopy with magnetic balloon and conscious sedation with midazolam and fentanyl were performed in four Caucasian patients (50-74 yrs, 3 males, BMI: 24,6- 37,1). All patients completed the colonoscopy with magnetic balloon. Tortuosity, laxity and/or redundancy were identified in all cases. Magnetic balloon anchorage has been always achieved even in an obese male patient (BMI 37,1). No adverse events occurred.

Conclusion

Magnetic balloon technology may represent a new safe and effective on demand solution forcompleting very difficult colonoscopies and preventing rescheduling of a second procedure.
