OBJECTIVE: To investigate the safety and outcomes of hiatal hernia repair (HHR) and fundoplication in patients with severe esophageal dysmotility (SED) or complete esophageal aperistalsis (scleroderma-like esophagus).
METHODS: Retrospective review of patients with SED (distal contractile integral < 500 mm Hg/cm/s) on high resolution esophageal manometry (HREM), who underwent minimally invasive anti-reflux surgery from August 1, 2016 to September 1, 2019 at a single tertiary referral center.
RESULTS: Thirty-two patients with SED were identified, including 18 (56%) with scleroderma-like esophagus. Mean pre-operative Demeester score was 59.5. Approaches included robotic (28) or laparoscopic (4) and included Toupet (31) and Nissen (1) fundoplications. There was no 90-day mortality, and the mean length of stay was 2 ± 1.8 days (range 1-10 days). Oral diet was resumed at a mean of 1 day post-operatively, and only 2 patients required concomitant placement of a feeding tube, including one who required re-operation for primary repair of an iatrogenic duodenal injury. Four patients required esophageal dilation (1 during index operation and 3 postoperatively), and 1 patient required pyloric botulinum toxin injection. Symptomatic improvement was observed in 81% of patients (26/32), with 4 patients (13%) reporting complete resolution of preoperative symptoms. Median follow up duration was 20 months (range 2 weeks to 38 months).
CONCLUSIONS: Minimally invasive HHR and fundoplication is safe in patients with SED including complete aperistalsis and can result in significant symptomatic improvement. Objective post-operative studies and longer follow-up are warranted to confirm the benefits of anti-reflux surgery in this patient population.
