EP.TH.267Gastroesophageal Reflux Disease after sleeve gastrectomy
Abstract Aim A prominent complication of a sleeve gastrectomy is gastroesophageal disease (GERD). Symptoms include chest pain, dysphagia, heartburn, regurgitation, chronic cough, and laryngitis. With the rise in obesity, and the already high prevalence of GERD in these populations, this is a significant cause of morbidity in western populations and is likely set to worsen. Method The literature search was carried out using Ovid MEDLINE and PubMed databases to search for keywords and MeSH terms including “bariatric surgery”, “sleeve gastrectomy”, “complications”, “gastroesophageal reflux disease”, “GERD”, “GORD”, and “obesity”. Result Approximately 20% of patients who undergo SG will develop de-novo GERD whilst 19% will have an increase in reflux symptoms. The exact mechanism of GERD in both obesity and post-operatively following SG is unclear. However, it can involve several different mechanisms. This includes poor surgical technique, disruption to physiological anatomy, increase in gastric pressure, increased risk of hiatus hernia, and disruption to normal hormonal balance. An effective approach to treat GERD includes the Stretta procedure with studies showing 72% of patients being symptom-free after 10 years. If this fails, conversion of SG to Roux-en-Y is effective but there is an increased risk of gastro-jejunal anastomotic leak (3% vs 1%). Alternatively, addition of hiatoplasty and 180° cardioplication can also be effective. Conclusion More evidence and international collaborations would help determine which patient groups require counselling and will benefit from novel management to minimise complications.
