Assessing esophageal motility after partial fundoplication for reflux

High Resolution Manometry After Partial Fundoplication for Gastro-oesophageal Reflux: Does the Ineffective Preoperative Oesophageal Motility Change Postoperatively?

NA · Spital Limmattal Schlieren · NCT05132816

This study is testing how a surgery for acid reflux affects the way food moves through the esophagus in patients who have had or will have the procedure.

What this trial studies

This study evaluates patients who have undergone or are scheduled for laparoscopic partial fundoplication to treat gastroesophageal reflux. It aims to assess preoperative ineffective esophageal motility and hypothesizes that these motility disorders are caused by reflux. Postoperative high-resolution manometry will be used to determine changes in esophageal motility. The study also examines secondary endpoints, including the presence of new motility disorders and gastrointestinal symptoms before and after surgery.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with ineffective esophageal motility disorders who are scheduled for partial fundoplication.

Not a fit: Patients with normal preoperative esophageal motility or specific motility disorders like Nutcracker or Jackhammer esophagus may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve postoperative outcomes for patients with esophageal motility disorders related to gastroesophageal reflux.

How similar studies have performed: While there is existing research on esophageal motility and fundoplication, this specific approach is novel in its combined retrospective and prospective assessment.
