Background/Aims
Radial incision and cutting (RIC) is an alternative dilation method for stenosis of the lower gastrointestinal tract. However, its safety and efficacy for the small intestine requiring balloon-assisted enteroscopy (BAE) remain limited. Therefore, this pilot study aimed to evaluate the safety and efficacy of RIC using BAE.
Methods
We included 10 patients with Crohn’s disease and performed 12 sessions of RIC for 10 lesions. The rate of adverse events 1 month after RIC was the primary outcome, whereas short- and long-term prognoses and improvements in subjective symptoms that were evaluated using a visual analog scale were the secondary outcomes.
Results
The technical success rate for RIC, defined as scope passage immediately following the procedure, was 100% (12/12). The rates of delayed bleeding and perforation were 0% (0/12). One patient developed restenosis because of the worsening of Crohn’s disease and underwent surgery 2 months after RIC. The cumulative restenosis-, reintervention-, and surgery-free rates at 1 year after RIC were 67.5%, 78.7%, and 90.0%, respectively. Abdominal pain, abdominal bloating, nausea, and difficulties in defecation significantly improved 4 weeks after RIC.
Conclusions
RIC for small intestine using BAE has the potential to be safe and effective for relieving symptoms (jRCT identifier jRCTs022200040).
