BOMSS has released a position statement on mini gastric bypass operations (MGBs).
In an MGB, the stomach is divided to form a long gastric pouch with subsequent anastomosis of that pouch to the jejunal loop. The narrow tube of gastric pouch affords a restrictive component and the bypassed small bowel contributes the malabsorptive element.
BOMSS has published a position statement on the use of MGBs which describes its benefits as including the requirement for a single anastomosis – making it a more technically simple operation than other options and one which has fewer potential sites for leaks and internal hernias.
Professor Duff Bruce, BOMSS member and consultant surgeon at Aberdeen Royal Infirmary, said; “Results to date suggest non-inferiority of MGB compared to the gold standard Roux-en-Gastric bypass in terms of mortality, weight loss, comorbidity resolution and quality of life.
“If the MGB is introduced into routine bariatric surgical practice it is recommended that it is within the confines of careful prospective data collection by surgeons working within the framework described in BOMSS Professional Standards guidelines. Follow-up data should be submitted to the National Bariatric Surgery Registry.”
Some potential disadvantages of MGBs have been noted and include the possible risk of reflux, a theoretical association between biliary reflux and oesophageal carcinoma and a lack of long-term outcome data.
BOMSS will review its MGB position statement after two years.
