Purpose:
Controversy remains about the treatment of patients with mild delayed gastric emptying (90 min < emptying half-time [T(1/2)] < 180 min) who undergo antireflux surgery. This retrospective, nonrandomized study reviewed the records of patients treated from January 1996 through October 2003, during which time we applied two treatment algorithms for patients with mild delayed gastric emptying. The goal of this study was to determine whether the most recent treatment algorithm was effective in reducing the need for a concomitant gastric drainage procedure, pyloroplasty.
Materials And Methods:
Eighteen patients with mild delayed gastric emptying underwent antireflux surgery plus pyloroplasty (group A) before 2001, and 13 patients with mild delayed gastric emptying underwent antireflux surgery plus gastric decompression with percutaneous endoscopic gastrostomy placement (group B) starting in 2001. We reviewed indications for the procedure, complications, and outcomes. Primary outcome measures for this study were recurrence of gastroparesis symptoms and need for pyloroplasty.
Results:
The average T(1/2) was similar for both groups A and B: 129 min and 123 min, respectively. Eleven of 13 patients (85%) in group B experienced resolution of gastroparesis symptoms, improved gastric emptying times, or both; only 1 patient (8%) underwent subsequent pyloroplasty for treatment failure. Only one serious percutaneous endoscopic gastrostomy-related event occurred (tube migration), and no patients died. Significantly fewer patients in group B required total pyloroplasty (8% vs. 56% in group A; P < 0.008), and significantly fewer required pyloroplasty for symptomatic control (15% vs. 56% in group A; P < 0.03).
Conclusion:
A treatment algorithm incorporating percutaneous endoscopic gastrostomy tube placement at the time of antireflux surgery for gastric decompression successfully managed antireflux surgery patients with mild delayed gastric emptying. This approach allows for a more selective use of pyloroplasty.
