title: Parietal cell vagotomy performed with fundoplication for esophageal reflux.
abstract: BACKGROUND
  Reduction of acid secretion is an important aspect of medical treatment of reflux esophagitis. Truncal vagotomy and drainage procedures used in conjunction with antireflux procedures to reduce acid secretion in patients with gastroesophageal reflux were unsatisfactory. This study reviews the results of parietal cell vagotomy used in conjunction with a 360-degree fundoplication to determine if reduction of acid by this form of vagotomy was beneficial to patients with gastroesophageal reflux.
  
  
  METHODS
  Between March 1973 and May 1993, 94 private and 64 Veterans Administration patients underwent parietal cell vagotomy and Nissen type fundoplication for esophageal reflux. Esophagogastroduodenoscopy (EGD), gastric analysis, cine-esophagogram, and 24-hour esophageal pH and motility studies were performed preoperatively on VA patients. Private patients underwent EGD, cine-esophagogram, and sometimes pH and motility studies. Similar studies were performed postoperatively if the patient permitted. The major technical alteration made during the study was the addition of posterior gastropexy to the operations performed between March 1978 and January 1987. Patients were considered failures if dysphagia and reflux symptoms were moderate but operation not contemplated (Visick III) or symptoms were severe and reoperation had been performed or was contemplated (Visick IV).
  
  
  RESULTS
  There were no operative deaths. There were 25 operative failures; dysphagia contributed to failure in 4, reflux in 11, and dysphagia and reflux in 10 patients. Reoperation was required in 6 patients. There was no statistical difference in acid secretion inhibition for patients with or without postoperative reflux symptoms. The cumulative probability for operative failure was 9.3 +/- SE 4.2% for patients who underwent posterior gastropexy and 22.9 +/- SE 4.6% (P <0.02) for those who did not.
  
  
  CONCLUSIONS
  Parietal cell vagotomy with Nissen fundoplication is a safe operation. The exposure created by PCV protected the vagi from injury. The study design made it impossible to determine whether PCV improved the results of fundoplication but the failure rate was significantly (P <0.02) reduced by the addition of posterior gastropexy. This may have lessened the risk of disintegration of the wrap that might be more likely to occur after PCV.
