title: [Long-term result of total versus partial fundoplication following esophagomyotomy for primary esophageal motor disorders].
abstract: OBJECTIVE
  To compare the long-term results of total and partial fundoplication on esophagus myotomy.
  
  
  METHODS
  From January 1978 to October 1998, 64 patients with achalasia or diffuse esophageal spasm underwent esophagomyotomy and antireflux operation via left thoracotomy. Twenty-one patients underwent Nissen total fundoplication (Nissen group) and 43 patients underwent Belsey Marker IV partial fundoplication (Belsey group). Clinical, radiologic, radionuclide transit, manometric, 24-hour pH monitoring and endoscopic assessments were performed before and after the operation.
  
  
  RESULTS
  There was no operative death and major complications for either group. At over 6 years follow-up and compared to Belsey group, patients in Nissen group revealed a higher frequency of dysphagia (P = 0.025) and more radionuclide material retention (P = 0.044). Both operative procedures reduced the lower esophageal sphincter pressure gradient. However, in Nissen group, the esophageal diameter observed on radiology was significantly increased from 3.9 cm preoperatively to 5.5 cm postoperatively (P = 0.012), while it kept the same for Belsey group (from 5.4 to 5.3 cm, P = 0.695). Reoperation in order to relieve the recurrent dysphagia and esophageal obstruction was performed on 8 patients in Nissen group and 1 in Belsey group (P < 0.01).
  
  
  CONCLUSIONS
  When treating achalasia or diffuse esophageal spasm by esophageal myotomy and an antireflux operation, a total fundoplication is not appropriate, whereas a partial fundoplication provides proper antireflux effect without significant esophageal emptying difficulty.
