One Anastomosis Gastric Bypass Surgery Dallas, Fort Worth, Mansfield & Plano

One Anastomosis Gastric Bypass (OAGB), also known as Omega Loop Gastric Bypass, Mini Gastric Bypass, and Single Anastomosis Bypass, is a type of gastric bypass surgery. Commonly performed through laparoscopy, OAGB is a relatively new weight loss surgery introduced by Dr. R. Rutledge in 1997 as a simpler alternative to traditional gastric bypass surgery (ROUX-en-Y). It is a restrictive and malabsorptive weight loss procedure involving the creation of a mini-gastric pouch and bypassing of an intestinal loop. The procedure has shown positive weight loss results for morbidly obese patients and involves rare chances of complications.

How Does One Anastomosis Gastric Bypass Work?

One Anastomosis Gastric Bypass is a two-part procedure that aims to limit the amount of food intake, lower the absorption of calories and nutrition, and change the hunger signals in obese patients. It involves:
  • Creating a narrow and longitudinal gastric pouch: A major part of the stomach is divided and stapled to create a small and long pouch. This has a much smaller curvature than gastric pouches created in traditional gastric bypass surgeries.
  • Jejunal bypass: The newly created gastric pouch is connected with the lower portion of the small bowel just below the pouch, thereby bypassing the upper loop of the small bowel.

Comparison with Traditional Gastric Bypass

Although both the ‘gold standard’ traditional gastric bypass and mini gastric bypass present positive weight loss results, the latter has certain potential advantages. These include:
  • OAGB is simpler than ROUX-en-Y and may have fewer risk of complications
  • OAGB has shorter surgery and recovery time
  • OAGB has lower chances of long-term complications such as acid reflux
  • OAGB is a comparatively flexible weight loss procedure. It can be revised and reversed, which is not easily possible nor recommended for ROUX-en-Y patients

Benefits of One Anastomosis Gastric Bypass Surgery

  • Significant weight loss
  • Minimal complications
  • Better management of obesity-related diseases including diabetes and hypertension
  • Shorter recovery time: Quicker return to daily activities post-surgery.
  • Reduced hunger: The surgery affects hunger hormones, leading to decreased appetite.
  • Improved quality of life: Enhanced physical mobility and self-confidence post weight loss.

Potential Complications with OAGB Surgery

Short-term risks Include :

  • Stomach leaks
  • Infections
  • Excessive bleeding and blot clots

The long-term risks with mini gastric bypass include :

  • Malnutrition
  • Dumping syndrome
  • Acid Reflux
  • Malnutrition
  • Hernia
  • Ulcers
  • Nausea and vomiting
  • Bile Reflux
OAGB still has a comparatively low complication rate among weight loss surgeries. Having said that, it is best to discuss your medical history with our weight loss surgery experts, Dr. Sachin Kukreja, Dr. Elizabeth Hooper, and Dr. Rebecca Barr to find out whether the procedure is right for you.

Patients considering mini gastric bypass must keep in mind that this weight loss surgery is a restrictive and malabsorptive procedure, which results in reduced nutrient absorption, changes in the gut microbiome, and altered energy homeostasis. It may also involve making sustainable lifestyle changes, dependency on nutrients supplements, and regular follow-ups with your bariatric doctor.
