- Abstract
Objectives: Radial incision and cutting (RIC) is being investigated as an alternative endoscopic dilation method for lower intestinal tract stenosis, providing a high technical success rate and improving subjective symptoms. However, several patients develop re-stenosis following RIC. In this pilot study, we aimed to evaluate the safety and efficacy of triamcinolone acetonide (TA) addition after RIC., Methods: RIC with TA was performed in 20 patients with lower gastrointestinal tract stenosis. We evaluated the rate of adverse events 2 months after RIC with TA. We investigated the short- and long-term prognoses, as well as the improvement in subjective symptoms, using a visual analog scale., Results: The delayed bleeding rate after RIC was 23.8%. Endoscopic hemostasis was achieved in all patients with delayed bleeding. No perforations were observed. The cumulative re-stenosis-free, re-intervention-free, and surgery-free rates 1 year after RIC were 52.9%, 63.7%, and 85.2%, respectively. Subjective symptoms, including abdominal pain, abdominal bloating, nausea, and dyschezia, significantly improved after RIC with TA., Conclusion: Although additional TA administration after RIC could be safe, additional TA may not be effective on luminal patency after dilation. Further investigation is warranted., Competing Interests: The authors declare no conflict of interest., (© 2024 The Author(s).
