Abstract
Vigorous achalasia has been considered an indication for surgery, in which a thoracic approach is recommended for extending the myotomy along the whole of the oesophageal body to the point where manometry shows high-amplitude waves. Clinical results and postoperative manometric findings in 16 patients with vigorous achalasia undergoing abdominal surgery with myotomy limited to the lower oesophageal sphincter (LOS) were analysed to assess whether extended myotomy is necessary in surgery for this form of achalasia. The clinical results were excellent or good in all cases. Surgery induced a significant decrease (P < 0·01) in the diameter of the oesophagus as determined radiologically. The most significant postoperative manometric changes were a decrease in the resting pressure of the LOS and oesophageal body, a lowering of wave amplitude at all levels of the oesophagus, and a reduction in the proportion of repetitive waves. The results suggest that vigorous achalasia can be treated surgically in the same way as classical achalasia and question, at least from a therapeutic viewpoint, the use of the term vigorous achalasia.
