The Rigiflex achalasia dilator system was used to treat consecutively 24 patients with achalasia. The 30-mm balloon achieved a 70% satisfactory result, and the 35-mm balloon, 93%, including two patients who did not achieve a good response to the smaller balloon. No complications occurred. Dilation pressure, which averaged only 7 +/- 2 (SD) lb/inch2 (psi), was determined by insufflating 1-2 psi more than needed for complete gastroesophageal waist expansion at fluoroscopy. The mean lower… CONTINUE READING
