The 90\u02da-swipe cryoballoon ablation system (CbSAS90) is a new technology incorporating cryotherapy that has been proposed to treat Barrett\u2019s esophagus (BE) segments. This technology is reportedly compatible with therapeutic endoscopes wherein a compliant balloon fills with cryogen and cools the esophageal wall to approximately -80 \u02daC. A quarter of the esophageal circumference and 3 cm of length is covered in a single application. This is a multicenter prospective study evaluating the safety and efficacy of CbSAS90 as a modality of Barrett\u2019s eradication therapy (BET). <\/p>\n\n\n\n
A total of 25 patients (median age, 67 years; 76% male) with a flat dysplastic BE segment \u22643 cm were enrolled in the study. Median procedure time was 24 minutes, and median ablation time was 10 minutes. The procedure was technically successful (treatment of all BE as intended) in 23 (92%) patients. Phase 1 involved semicircumferential therapy at 0.8 mm\/second and 0.7 mm\/second, yielding a BE surface regression of 78% and 85%, respectively. In Phase 2, circumferential treatment (2 semicircumferential treatments, 8 weeks apart) showed a BE surface regression of 93%. Overall, 2 (17%) patients developed stenosis requiring dilation. There were no reports of bleeding, perforation with low and acceptable pain, and dysphagia scores.<\/p>\n","protected":false},"excerpt":{"rendered":"
