Area of Science:

Gastroenterology
Surgical Outcomes
Patient-Reported Symptoms

Background:

Postprandial bloating is a frequent complaint among individuals with chronic gastroesophageal reflux disease (GERD).
Understanding the impact of surgical intervention on this symptom is crucial for patient management.

Purpose of the Study:

To assess the prevalence of postprandial bloating in chronic GERD patients.
To evaluate the effectiveness of laparoscopic Nissen fundoplication in alleviating bloating symptoms.
To identify factors contributing to postprandial bloating before and after surgery.

Main Methods:

Prospective cohort study involving 578 patients with proven GERD.
Laparoscopic Nissen fundoplication as the surgical intervention.

Assessment of symptom severity scores for bloating and dysphagia, esophageal motility, and 24-hour pH monitoring pre- and post-surgery.

Main Results:

Preoperatively, 73% of patients reported postprandial bloating; this significantly improved after surgery (p < 0.0001).
At 6 months post-surgery, 54% experienced bloating, with 49% reporting improvement, 21% worsening, and 30% no change.
Worsening bloating in a subgroup of patients at 6 months often improved by the 2-year follow-up.

Conclusions:

Postprandial bloating is highly prevalent in chronic GERD patients.
Laparoscopic Nissen fundoplication generally reduces bloating severity.
While some patients may experience temporary post-surgical bloating exacerbation, it tends to improve over time.
