The researchers investigated laparoscopic antireflux surgery and its effect on cough in patients with gastroesophageal reflux disease (GERD).
They reported their findings in the Journal of Gastrointestinal Surgery.
In addition to heartburn and regurgitation, cough is a frequent nonspecific complaint of patients with GERD.
The incidence of alternative etiologies for patients with chronic cough, who are undergoing antireflux surgery, is not known.
The authors performed a retrospective review of 129 patients with proven gastroesophageal reflux referred for surgical therapy.
Chronic cough was present in 29% preoperatively.
| Antireflux surgery completely resolved cough in 64% of patients.

No differences were found in age, sex, or preoperative manometric findings between those with and without chronic cough.
Patients with cough had a higher number of lower esophageal reflux events on preoperative 24-hour pH testing. They were also more likely to have persistent dysphagia after surgery.
The investigators found that 59% of patients with cough had an alternative etiology for cough, compared to 36% of those without cough.
Of the common alternative etiologies, only a history of postnasal drip occurred more frequently in those with cough.
Complete resolution of cough occurred in 64% of patients, with another 27% reporting significant improvement.
The average cough score improved significantly, regardless of which coexisting etiology the patients may have had.
Additionally, heartburn and regurgitation were improved in 94% of all patients.
