โœฆ Synopsis


We investigated the long-term efficacy and safety of intrasphincteric injections of botulinum toxin (100 U) in 57 patients with esophageal achalasia. One month after treatment, 50 patients had improved (88%); both symptom score and LES pressure were significantly reduced (P < 0.001). After a mean follow-up of 24 ยฑ 15 months (range 6-48), 43 patients (75%) are still in remission, although repeat injections of toxin were needed to achieve a stable effect on symptoms.
