Botulinum toxin treatment of oesophageal achalasia in the old old and oldest old: a 1-year follow-up study.

BACKGROUND

Intrasphincteric injection of botulinum toxin (BTX) has become one of the most frequent therapeutic approaches for the treatment of oesophageal achalasia. This treatment seems particularly effective in elderly patients who are not candidates for more invasive procedures.

AIMS

There are few or no data on BTX treatment of achalasia in the old old and oldest old. Therefore, we evaluated BTX treatment in a group of patients with achalasia in the extreme age range who were too ill or frail to undergo surgery or pneumatic dilatation.

PATIENTS AND METHODS

Twelve elderly achalasic patients (age range 81-94 years, average age 86 years) with American Society of Anesthesiologists (ASA) class III-IV status were recruited for the study. After baseline clinical and instrumental evaluations, BTX 100U was injected at time 0 and 1 month later. Clinical follow-up was carried out after 3, 6 and 12 months.

RESULTS

A significant improvement in symptom score was documented at each follow-up step. On the basis of improvements in scores, approximately 70% of patients were considered responders at the end of follow-up.

CONCLUSIONS

BTX treatment is an effective treatment in a substantial proportion of achalasic patients >80 years of age, in whom benefits are still detectable after 12 months. BTX is a therapeutic option in patients unsuitable for surgery or pneumatic dilatation.
