[Evaluation of pre- and post-operational esophageal manometric findings with achalasia].

OBJECTIVE

To evaluate the manometric feature of pre- and post-operation with achalasia and the result of surgical myotomy through abdominal incision.

METHODS

The manometric studies were performed in 23 pre- and 11 post-operational patients, including 11 patients who received both pre- and post-operational studies. 24 hour pH monitoring was performed in 11 after surgical myotomy.

RESULTS

Achalasia, a motor disorder of the esophageal body, and hypertension of the resting LES impaired relaxation. The incidence of reflux was 22.2%.

CONCLUSIONS

Surgical myotomy through abdominal incision is an effective procedure. It is necessary to avoid LES incompetence or reflux esophagitis.
