Safety and efficacy of liquid nitrogen spray cryotherapy-assisted balloon dilation for refractory anastomotic strictures.

This article discusses the use of liquid nitrogen spray cryotherapy-assisted balloon dilation for refractory anastomotic strictures. The study analyzed a case series of seven patients with refractory strictures at anastomotic sites. The results showed that cryo-dilation was safe and effective, with a significant reduction in the number of dilation procedures required after the treatment. However, the study is limited by its small sample size and short follow-up period, and further research is needed to validate the technique and assess its long-term effects.
