Antireflux surgery enhances gastric emptying

Area of Science:

• Gastroenterology
• Surgical Innovation
• Digestive Physiology

Background:

• Gastroesophageal reflux disease (GERD) significantly impacts patient quality of life.
• The effect of antireflux surgery on gastric motility remains an area of clinical interest.
• Understanding post-surgical gastric emptying is crucial for managing GERD patients.

Purpose of the Study:

• To investigate the impact of antireflux surgery on gastric emptying.
• To assess changes in gastric emptying before and after surgical intervention for GERD.
• To correlate surgical outcomes with alterations in digestive physiology.

Main Methods:

• A nonrandomized controlled trial involving 20 GERD patients and 10 healthy controls.
• Gastric emptying scintigraphy using solid food was performed preoperatively and 3 months postoperatively.
• Nissen fundoplication or Toupet hemifundoplication was performed for surgical intervention.

Main Results:

• Antireflux surgery led to a significant decrease in the mean time to halving of maximal gastric activity (113 to 78 minutes, P = .001).
• Postoperatively, 19 out of 20 patients became symptom-free, with resolution of pyrosis and regurgitation.
• While preoperative gastric emptying was slower in patients than controls, it became faster postoperatively, though not significantly different.

Conclusions:

• Antireflux surgery effectively enhances gastric emptying in patients with GERD.
• Surgical intervention results in symptom cessation and promotes healing of esophagitis.
• The study demonstrates a positive influence of antireflux procedures on digestive function.
