NCT00188344

Brief Summary

The purpose of this study is to compare pneumatic dilatation and laparoscopic Heller myotomy in patients with achalasia in order to learn which of these two treatments should be recommended to patients in the future.

Study Arms (2)

1

ACTIVE COMPARATOR

pneumatic dilatation

Procedure: pneumatic dilatation

2

ACTIVE COMPARATOR

Laparoscopic myotomy

Procedure: laparoscopic myotomy with partial fundoplication

Interventions

The patient is on a liquid diet for 2 days prior to procedure. A sedative and pain killer by IV are given and the throat will be sprayed with local anesthetic. The gastroenterologist may perform an endoscopy prior to the dilatation to safely guide the dilator into position. A special dilator with a small balloon will be passed down the esophagus until it meets the stomach then the balloon will be inflated with air until the narrow part of the esophagus is opened. The patient will then be assessed for any perforation of the esophagus and monitored in the post-procedure unit for a few hours.

1

The abdomen is inflated with gas and cameras and instruments are inserted. The junction between the esophagus and stomach is identified. The muscle of the lower esophageal sphincter is divided. A portion of the stomach wall is secured to the lower esophagus. After surgery the patient is taken to the recovery room and when well enough moved to a ward. The patient may be discharged the following day.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical diagnosis of achalasia by a physician
  • manometric diagnosis of achalasia including both: Incomplete relaxation of the lower esophageal sphincter during swallowing (\<80% of elevation over intragastric pressure and absence of esophageal peristalsis (peristalsis in \<20% of initiated contractions)
  • Facility with English, ability to complete English language questionnaires

You may not qualify if:

  • Pseudoachalasia: esophageal carcinoma; esophageal stricture; previous esophageal or gastric surgery; previous instrumentation of the lower esophageal sphincter i.e. suture, polymer injection, silicone band
  • Previous gastric or esophageal surgery: fundoplication; Heller myotomy; gastric resection; vagotomy with or without gastric drainage
  • Age 17 year or less
  • Pregnancy
  • Presence of severe comorbid illness: unstable angina; recent myocardial infarction (\<6 months), cancer (except integumentary), unless free of disease for more than 5 years; end stage renal disease; previous stroke with cognitive, motor speech, or swallowing deficit persisting longer than one month; severe respiratory disease; cognitive impairment
