The LRYGBP provides the best balance between malabsorption and malnutrition plus sustained long term results. Because of these features it has been the most frequent bariatric procedure in recent years.
However, some groups report that between 10% and 35% of patients display insufficient weight loss or weight regain after a LRYGBP. There is an increasing number of patients with this problem and all the obesity related professionals are currently dealing with this issue.
Variations in the anatomy of the pouch (its volume and the diameter of the gastro jejunal anastomosis) have been pointed out as responsible for the unfavorable weight loss evolution in these patients.
As a joint effort the surgeons, endocrinologists, endoscopist and pathologist of the Obesity Unit in the Institut Clínic de Malalties Digestives i Metabòliques at the Hospital Clínic of Barcelona have decided to address this issue.
To achieve this goal they are obtaining volumetric data of the pouch, the blind loop and alimentary limb by a CT Scan and measuring the anastomosis by upper endoscopy. They hope that the results of this investigation will make it possible to tailor the best surgical treatment for their patients.
The working group is currently collecting the data and the results will soon be available.
