Summary

The goal of this clinical trial is to learn if people can safely skip a test called esophageal manometry before surgery for acid reflux (gastroesophageal reflux disease, or GERD) or a hiatal hernia. Manometry measures the muscles of the food pipe using a thin tube passed through the nose. The test can be uncomfortable and can delay surgery. The main questions this study aims to answer are whether people can skip manometry and still have good swallowing one year after surgery, and whether skipping the test lowers discomfort, shortens the wait for surgery, and lowers cost. To answer this, researchers will compare two groups. One group will have surgery without manometry. The other group will have manometry first, the way it is usually done. Everyone will get the same operation, a partial wrap called a Toupet fundoplication, so the study tests the value of the test and not the surgery. Participants will be placed by chance into one of the two groups, have the same standard operation, and fill out short questionnaires about their swallowing before surgery and again at 3, 6, and 12 months after surgery. Researchers want to find out if skipping manometry works just as well as the usual approach for people who do not have trouble swallowing before surgery.

Conditions

  • GERD
  • Hiatal Hernia
  • Heartburn
  • Paraesophageal Hernia
  • Gastroesophageal Reflux

Interventions

PROCEDURE

Preoperative workup without high-resolution esophageal manometry

Participants assigned to this intervention will not undergo routine high-resolution esophageal manometry before surgery. They will complete the remaining preoperative assessment, including EGD and imaging, with ambulatory pH testing performed only if clinically indicated at the discretion of the treating surgeon.

PROCEDURE

Standard preoperative workup with high-resolution esophageal manometry

Participants assigned to this intervention will undergo a standard preoperative workup, including EGD, imaging, optional ambulatory pH testing at the treating surgeon's discretion, and high-resolution esophageal manometry before surgery. Participants will then proceed to standardized laparoscopic Toupet 270-degree posterior partial fundoplication with hiatal hernia repair.
