Plain English Summary
Background and study aims
Obesity often leads to problems of heartburn (burning sensation in chest) and regurgitation (taste of acid in throat or mouth), which fall under the category of gastroesophageal reflux disease (GERD). The study compares two types of procedures and the aim is to identify if it is possible to treat both obesity and GERD at the same time.
Who can participate?
Adults with severy obesity combined GERD symptoms.
What does the study involve?
Participants are randomly allocated to one of two groups:
Group 1 - laparoscopic great curvature plication (which reduces the stomach by creating an internal fold) and laparoscopic fundoplication (for GERD)
Group 2 - laparoscopic fundoplication only.
What are the possible benefits and risks of participating?
Direct benefit will be healing of heartburn and other symptoms of GERD. Possible side effect is the risk of persistent difficulty in swallowing (called dysphagia).
Where is the study run from?
Single center of Akmola Regional Hospital № 2 (Kazakhstan).
When is the study starting and how long is it expected to run for?
From January 2010 to December 2015
Who is funding the study?
Scientific and Educational Centre for Development of Laparoscopic Surgery in Kazakhstan

Scientific title
Laparoscopic Surgery for Severe Obesity combined with gastroesophageal reflux disease: a pilot single-centre single-blind two-arm randomised controlled study
Acronym
Study hypothesis
1. An elevated body mass index (BMI) frequently results in the development of gastroesophageal reflux disease (GERD) symptoms, amongst which heartburn and regurgitation are the most common complaints,
2. Laparoscopic great curvature plication and laparoscopic fundoplication provide an anti-reflux effect similar to the standard Nissen laparoscopic fundoplication, at the same time significantly surpassing it in terms of bariatric effectiveness.
