OBJECTIVE: To investigate the outcomes of hiatal hernia repair (HHR) and fundoplication with or without pyloromyotomy or pyloroplasty in patients with gastroesophageal reflux disease (GERD) and gastroparesis.
METHODS: Retrospective review of all patients with GERD and gastroparesis as defined by greater than 60% or 10% gastric retention of solids at 2 hours and 4 hours respectively, who underwent minimally invasive anti-reflux surgery with or without pyloromyotomy or pyloroplasty from August 1, 2016 to September 1, 2019 at a single tertiary referral center.
RESULTS: Thirty-six patients with delayed gastric emptying were identified with a mean 2-hr and 4-hr gastric retention of 63% and 27% respectively. All cases were performed robotically and included Toupet (14), Nissen (21), and 1 partial anterior fundoplication. There was no 90-day mortality and the mean length of stay was 2 ± 1.49 days (range 0-8 days). Median follow up duration was 5 months (10 days to 30 months). Symptomatic improvement was observed in 86% of patients (31/36). Five patients had repeat gastric emptying studies postoperatively, with 2 patients resulting in normalization compared preoperatively. Symptomatic improvement was observed in 87.5% (14/16) of patients who received either a pyloroplasty or pyloromyotomy as opposed to 80% (16/20) who received neither.
CONCLUSIONS: Minimally invasive HHR and fundoplication with or without pyloromyotomy or pyloroplasty is safe and effective in patients with GERD and gastroparesis. A randomized control trial with post-operative objective measurement of gastric emptying and reflux is necessary to confirm the benefits of surgery in this patient population.
