Study information
Scientific title
A randomized controlled trial of laparoscopic Nissen fundoplication versus proton pump inhibitors for the treatment of patients with chronic gastroesophageal reflux disease (GERD): 3-year outcomes.
Acronym
ELVIS (oEsophagitis - Laparoscopy Versus Inhibitors of Secretion)
Study hypothesis
1. Laparoscopic Nissen Fundoplication (LNF) is an effective intervention in the management of patients with chronic Gastro-oEsophageal Reflux Disease (GERD) requiring maintenance therapy
2. LNF is cost-effective compared with long-term medical therapy
3. LNF is more effective than maximum medical therapy in control of respiratory symptoms and complications of GERD
Ethics approval
Ethics approval received from Research Ethics Board of St Joseph's Hospital on the 30th March 2000.
