Background: Although gastroparesis does not influence gastroesophageal reflux disease (GERD) or antireflux surgery, many patients with GERD will also suffer from gastroparesis-related bloating as a distinct symptom different from GERD-related symptoms. The purpose of this study was to assess whether a pyloroplasty with a fundoplication will improve bloating symptoms in these patients.
Methods: A prospectively gathered database of all patients undergoing antireflux surgery was reviewed. All patients underwent history, physical examination, upper gastrointestinal endoscopy, esophageal manometry, 24-hour esophageal pH monitoring, and, selectively, contrast upper gastrointestinal radiography. Patients with symptoms of bloating also underwent gastric emptying scintigraphy. All patients completed the GERD-Health Related Quality of Life (HRQL) symptom severity questionnaire. One of the items of this instrument relates to bloating. The item is scored from 0 (asymptomatic) to 5 (incapacitating) based on descriptive anchors. Patients with symptomatic GERD and objective findings by physiologic testing were offered antireflux surgery. Those with delayed gastric emptying (defined as T(1/2) > 120 minutes) were also offered a pyloroplasty. Operations performed included a laparoscopic or open Nissen or Toupet fundoplication with a Heineke-Mickulicz pyloroplasty. Postoperatively, patients completed the GERD-HRQL and had a gastric emptying scintigraphy performed.
Results: Three-hundred and sixty-nine patients underwent antireflux surgery; of these, 35 patients also had a pyloroplasty. Twenty-eight (80%) of these patients reported significant symptomatic improvement. The median preoperative bloating score improved from 4 to 1 postoperatively (P < 0.05), and the median gastric emptying scintigraphy T(1/2) improved from 244 to 112 minutes (P < 0.05).
Conclusions: Although gastroparesis may not contribute to symptoms of GERD, it can contribute to symptoms of bloating. Bloating symptoms improved in 80% of patients with the addition of a pyloroplasty. Therefore, addition of pyloroplasty to a fundoplication in patients with gastroparesis-related bloating can improve bloating symptoms.
