Background
Altered gastric anatomy following laparoscopic sleeve gastrectomy (LSG) is likely to induce upper gastrointestinal (GI) symptoms. Published studies, however, have focused mainly on gastroesophageal reflux disease (GERD). This study aims to evaluate LSG's impact on the prevalence of upper GI symptoms and to assess the effects of time from surgery, weight loss, and proton pump inhibitor (PPI) therapy.
Methods
The validated Rome III Criteria symptom questionnaire for upper GI symptoms, including quality of life items, has been self-administered to 97 patients who underwent LSG. Symptoms were analyzed either separately or altogether to classify patients in GERD or dyspepsia, subdivided in epigastric pain (EPS) and post-prandial distress (PDS) syndromes.
Results
Before LSG, 52.7 % of the patients were asymptomatic, 27.0 % had GERD, and 8.1 % had dyspepsia (2.7 % EPS, 5.4 % PDS). After a median follow-up of 13 months, 91.9 % of the patients complained of upper GI symptoms, the most prevalent being PDS (59.4 %). GERD prevalence did not differ before and after LSG. The only symptom strongly related to LSG was dysphagia (OR 4.7, 95 % CI 1.3–20.4, p = 0.015), which was present in 19.7 % of the patients and mainly associated with PDS rather than GERD. GI symptoms, however, did not have a great impact on quality of life. Time from surgery, weight loss after surgery, as well as concomitant PPI, did not influence the symptoms.
Conclusions
After a median follow-up of 13 months, PDS-like dyspepsia, rather than GERD, was the main complaint, both poorly responding to PPI therapy. A longer follow-up will be necessary to evaluate their future persistency.
