Gastric Bypass

Restriction and reduced absorption in one of the most clinically supported surgeries.

What is it?

About the gastric Bypass

Gastric bypass combines two mechanisms: reducing the stomach’s capacity to limit the amount of food, and modifying the intestinal path to reduce the absorption of calories and nutrients. It is one of the most supported bariatric surgeries, with strong results for weight control and metabolic diseases, and is performed laparoscopically. There are several techniques — each with its own features and advantages — that Dr. Escoto evaluates to choose the most suitable one for your case.

Techniques

Types of gastric bypass

There is no single bypass technique. The choice depends on your weight, associated conditions, and goals; the best balance of safety and results is defined during consultation.

Roux-en-Y gastric bypass

The classic, most studied technique. A small gastric pouch is connected to a section of the small intestine in a "Y" shape, combining restriction and reduced absorption. It is the reference standard for its long-term track record.

One-anastomosis bypass (OAGB)

Also called the "mini bypass." It uses a single connection between the gastric pouch and the intestine, which simplifies the technique and often shortens operating time while maintaining good results.

SASI bypass

Combines a gastric sleeve with a single anastomosis to the ileum. It largely preserves the natural path of food while boosting the metabolic effect, making it an attractive option for selected patients.

Transit bipartition

Starting from a gastric sleeve, a connection is added to a distal portion of the intestine, so food follows two routes while the passage through the duodenum is preserved. It stands out for its strong effect on metabolic diseases such as type 2 diabetes.

Each technique has different indications, advantages, and considerations. None is "the best" for everyone: the right one is defined individually after a complete medical evaluation.
Who is it for?

Candidates

  • Severe obesity or when a greater metabolic effect is sought.
  • Patients with type 2 diabetes, which may improve significantly.
  • People with significant gastroesophageal reflux.
  • Cases where other procedures are not the best alternative.
Benefits

What you can expect

  • Excellent long-term weight control.
  • Strong positive impact on type 2 diabetes and other metabolic diseases.
  • Often improves gastroesophageal reflux.
  • A widely studied procedure with decades of clinical experience.
Important considerations

What you should know

By reducing nutrient absorption, it requires lifelong vitamin supplementation and nutritional follow-up. It is a complex procedure indicated after a detailed evaluation.
FAQ

Common questions

How is it different from the gastric sleeve?

The sleeve only reduces the size of the stomach; the bypass also modifies the intestinal path to reduce absorption, which usually gives it a greater metabolic effect.

Will I need to take vitamins?

Yes, supplementation and nutritional follow-up are essential for long-term success and safety.

Is it safe?

It is one of the most studied procedures; like any surgery it carries risks, which are minimized with proper evaluation and an experienced team.
