Mini gastric bypass or single-anastomosis bypass – an attractive alternative?

According to a paper published in the Scandinavian Journal of Surgery, the single-anastomosis gastric bypass “may be an attractive alternative metabolic operation”. Also known as the one-anastomosis gastric bypass or mini gastric bypass, the procedure can result in a shorter operative time, fewer short- and long-term complications, improved and sustained excess weight loss and is more effective in terms of resolutions of comorbidities compared to standard RYGB, the paper states.

Introduced by Dr Robert Rutledge in 2001, the single-anastomosis bypass has increased in popularity due to its simplicity and apparent safety and effectiveness. The benefits include:

  • fewer sites for leakage and internal hernia
  • easier and faster to learn and perform
  • easier to reverse and revise
