Abstract
Background
Having accurate information on bariatric surgery-related gastrointestinal (GI) symptoms
is critical for patient care.
Objective
To report on surgery-related GI symptoms over the first 3 years following Roux-en-Y
gastric bypass and laparoscopic adjustable gastric band.
Setting
Three academic medical centers in the United States.
Methods
As a substudy of the Longitudinal Assessment of Bariatric Surgery Consortium, 183
participants (pre-surgery median body mass index = 45.1 kg/m2; median age = 46 yr; 83.1% female). completed the Eating Disorder Examination-Bariatric
Surgery Version interview at≥1 annual assessment. Patients self-reported frequency
of dysphagia, dumping syndrome, and spontaneous vomiting.
Results
Prevalence of dysphagia at least once weekly decreased post-laparoscopic adjustable
gastric band surgery from 43.9% (95% confidence interval [CI], 32.2–55.6) in year
1 to 27.5% (95% CI, 15.2–39.9) in year 3 (P = .02). Dysphagia and dumping at least once weekly also appeared to decrease in years
1–3 post-Roux-en-Y gastric bypass (i.e., from 16.7% [95% CI, 9.4–24.1] to 10.9% [95%
CI, 4.0–17.8] and from 9.9% [95% CI, 4.3–15.5] to 6.3% [95% CI, 1.7–10.9], respectively),
but power was limited to evaluate trends. Vomiting at least once weekly was rare (<6%)
in years 1–3 following both procedures. Controlling for potential confounders and
surgical procedure, loss of control eating at least once weekly was associated with
higher risk of at least once weekly dysphagia (relative risk = 2.01, 95% CI, 1.36–2.99,
P = .001).
Conclusions
The prevalence of bariatric surgery-related GI symptoms appears to decrease across
follow-up. Symptoms were associated with loss of control eating, suggesting a target
for clinical intervention.
