Does gastric resection have a role in the management of severe postfundoplication gastric dysfunction?

Background: Bloating, flatulence, early satiety, and dysphagia resolve in more than 90% of patients early after fundoplication. Gastric dysfunction can persist, however, and a small number of patients develop severe gastric dysfunction (gastroparesis). Management of gastroparesis after antireflux procedures is generally conservative, but gastroparesis can become refractory to medical therapy. The aim of this study was to assess the role of gastric resection in the management of the unusual patient with severe postfundoplication gastric dysfunction. Methods: From January 1990 to October 2010, a total of 5,129 gastric resections were performed at our institution. From this cohort, we identified nine patients with postfundoplication gastric dysfunction managed with gastric resection. Clinical records were reviewed retrospectively for preoperative evaluation, perioperative course, and long-term outcomes. Results: Over 20 years, nine patients were treated with gastric resection for debilitating gastric dysfunction after antireflux surgery. Seven of the nine patients were female; the median preoperative body mass index was 25 kg/m² (18-31 kg/m²). Median follow-up was 23 months (1-97 months). Preoperatively, five patients required enteral feeding. Postoperatively, although there were no deaths, one patient required operative drainage of a subphrenic abscess, one developed temporary respiratory failure, and one was readmitted for partial small bowel obstruction. Six of the nine patients maintain their nutrition orally, but three are maintained with enteral nutrition. Only two patients are subjectively asymptomatic. Conclusions: Outcomes after gastric resection for postfundoplication gastric dysfunction are poor, with three of the nine patients requiring supplemental nutrition and seven of the nine having persistent symptoms.
