Abstract
- Background Cryoballoon ablation could induce stricture formation to achieve outlet and pouch reduction in patients regaining weight after Roux-en-Y gastric bypass (RYGB). This pilot study aimed to assess technical feasibility and short-term efficacy. Methods A retrospective chart review (January – November 2018) at two academic centers identified patients with weight regain post-RYGB, treated with cryoablation if pouch > 4 cm and/or outlet > 15 mm. Patients were scheduled for surveillance endoscopies at 8 weeks. Results 22 patients presented 10.5 years (SD 4.42) post-RYGB with weight regain of 30.9 kg (SD 13.7). Technical success was 89.5 % for outlet ablation and 93.0 % for pouch ablation. From baseline to 8 weeks, the outlet was reduced from 24.1 mm (95 % confidence interval [CI] 19.8 to 28.5) to 17.1 mm (95 %CI 13.1 to 21.1; P Conclusion Cryoablation appears technically feasible and effective for outlet and/or pouch reduction in the short term.
