The mini-gastric bypass (MGB) consists of a long, narrow lesser curvature gastric pouch beginning below the crow’s foot, extending lateral to the esophagogastric (EG) junction, with a wide anastomosis to an antecolic jejunal loop at a point about 150–200 cm distal to Treitz’ ligament, providing malabsorption. The operation is brief, simple, and saf...
Surgery for severe obesity started in the 1950s. The development of different operations including variants of jejunoileal bypass, gastric bypass, gastric restrictive surgery, and biliopancreatic diversion are discussed in this chapter. The development of endoscopic procedures such as endoscopic sleeve gastroplasty and alternative approaches includ...
The mini-gastric bypass (MGB), which originated in 1997 as a simple, rapid, and mainly malabsorptive bariatric operation, is now increasing internationally. A variant of the MGB, started in Spain in 2002 with an anti-reflux mechanism, is called the one-anastomosis gastric bypass (OAGB or BAGUA); the OAGB is also commonly performed in Mexico and Lat...
The mini-gastric bypass (MGB) has proven to be a safe, rapid and effective weight-loss procedure. However, as with all abdominal operations, complications may still occur, and should be prevented if possible and treated appropriately. The authors discuss experience with the MGB.
Background:
Minigastric bypass (MGB) is being performed widely with effective weight loss and improvement in co-morbidities. Because of similarity to Billroth II (BII), there are concerns about bile reflux.
Objectives:
To assess the esophagogastric junction (EGJ) function, esophageal peristalsis, and reflux exposure after MGB and BII.
Setting:...
This book indicates the technique and fine points of the mini- and one-anastomosis gastric bypass, and looks at the means of revising other operations related to it. The chapters discuss postoperative complications, treatment and requirements, postoperative diet and medications, the remarkable effects on the co-morbidities of morbid obesity, and th...
Abstract
Introduction: Mini-Gastric Bypass (MGB) originated in 1997 as a simple,
rapid and mainly malabsorptive bariatric operation; it is now increasing rapidly.
Methods: History, technique, variations and world literature are reviewed.
Results: Reports now find the MGB to be a superior operation with respect
to safety, short learning curve, resol...
Background:
The improvement in glucose metabolism after bariatric surgery is well established. The aim of this study was to investigate the hormones and glycemic control in diabetes after a one-anastomosis gastric bypass (OAGB) variant in an animal model of non-obese type 2 diabetes mellitus.
Methods:
Thirty-six Goto-Kakizaki rats were randomly...
Surgery for severe obesity started in the 1950s. The development of different operations, including variants of jejuno-ileal bypass, gastric bypass, gastric restrictive surgery and biliopancreatic diversion are discussed. Laparoscopic surgery, and novel approaches including endoscopic procedures and neuromodulation are also presented.
The mini-gastric bypass (MGB) consists of a long, narrow lesser curvature gastric pouch beginning below crow’s foot, extending lateral to the esophagogastric (EG) junction, with a wide anastomosis to an antecolic jejunal loop at a point about 200 cm distal to Treitz’ ligament, providing malabsorption. The operation is brief, simple and safe, has pr...
Severe loss of activities of daily living, if noted, is a potent reason for weight-loss surgery.
Massive obesity results in serious diseases, which are a major public health problem. Surgery is frequently the only means to achieve and sustain significant weight loss. This historical overview is aimed at providing knowledge and appreciation of this surgery to scientists in other complex areas of nutrition. The development of these operations is...
Many thousand years ago, man suffered hunger and undernourishment. Our ancestors were hunters and gatherers, who worked hard and lived on a high protein diet. They developed “economy genes” to save energy for bad times efficiently. During the last 8,000 years, the development of an agricultural use of wild corn and cereals led to nutrition with mor...
Pursuant to our findings that pituitary basic fibroblast growth factor (bFGF) stimulates the replication of preadipocytes and inhibits their differentiation, we have studied the changes in expression of a bFGF-related mRNA during differentiation. Human omental preadipocytes were grown in primary culture and induced to differentiate with chemically...

Severe obesity is associated with type 2 diabetes mellitus, and both resolve with weight loss after bariatric operations. Intestinal hormones have been identified which are stimulated by rapid nutrient delivery to the lower small bowel after certain weight-loss operations. These incretins stimulate secretion and hypertrophy of the pancreatic beta c...

Scientific communication is a responsibility and obligation of the surgeon to enrich and advance knowledge. Reporting in journals is a means of achieving this interaction, which is particularly important in the developing field of bariatric surgery.
