Gastric Bypass Surgery - Gastric Bypass vs Mini Gastric Bypass

Gastric Bypass Surgery

In Gastric Bypass Surgery, the surgeon forms a stomach pouch, approximately 5-10% of the original stomach size while keeping the separated excess stomach in place to aid in digestion.

Mini Gastric Bypass Surgery - Gastric Bypass vs Mini Gastric Bypass

Mini Gastric Bypass Surgery

In Mini Gastric Bypass Surgery, the surgeon forms a tube-shaped stomach pouch that holds approximately 4 to 6 ounces of food. Bypasses an average of 20% of the small intestine.

Stomach Alterations

New stomach created: Stoma

  • The stomach is bypassed, with a new smaller stomach (stoma) created with intestines.
New stomach formed

  • The stomach is turned into a tube-shaped, with a new smaller stomach (stoma) created with intestines.

Changes to Intestine

Cut and Bypassed

  • The stoma is rerouted to bypass a large portion of intestines. This reduces absorption of nutrients and calories.
Cut and Bypassed

  • The stomach uses a single connection to the small intestine, known as single anastomosis.

Operating Time

  • 2 hours
  • 1.5 to 2.5 hours

Average Hospital Stay

  • 2 to 3 nights
  • 2-3 nights

Time off Work

  • 2 to 3 weeks
  • 2 to 3 weeks

Recovery Time

  • 3 weeks
  • 3 weeks

Pros

  • High Expected Weight Loss, Comparable to Duodenal Switch.
  • Gastric Bypass has been performed hundreds of thousands of times. Thus, side effects and complications are known.
  • High excess weight loss
  • Low-risk procedure in comparison to Gastric Bypass

Disadvantages

  • Major and complicated surgery with associated risks.
  • Leakage, bleeding, vomiting can occur.
  • Daily supplements and vitamins needed.
  • Dumping syndrome is common.
  • Newer Procedure
  • Less long-term results as Gastric Bypass
  • Vitamins and supplements needed.

Surgery Description

Small pouch (about 1 oz/15-30 cc) Pouch is connected to the small intestine where food and digestive juices are separated for the first 3 to 5 feet. The RNY significantly restricts the volume of food that can be eaten.

Small tube-like stomach (about 2 to 3 oz/25 to 45 cc) is connected to the small intestine where food and digestive juices are separated for the first 4 to 6 feet.

Realistic Expectations

  • Provides mild malabsorption of nutrients
  • Patients can expect to lose 70% of excess weight.
  • Less than patients with Duodenal Switch.
  • Provides mild malabsorption of nutrients
  • Patients can expect to lose an average of 76% of excess weight
  • Less than patients with Duodenal Switch

Post Surgery Dietary Info

  • Patients must eat three small meals a day.
  • Patients must avoid sugar and fats to prevent Dumping Syndrome.
  • Patients must take vitamin and protein supplements to avoid deficiency (Multivitamin, Calcium, Vitamin B12, and Iron for menstruating women)
  • Bypass patients need to be on vitamins for the rest of their life to aid in digestion

Results

Gastric Bypass is effective for patients with a BMI of 35-55 and those with a “sweet tooth.”

The new stomach will hold about 2 to 3 ounces of food instead of the average 40 ounces.

The mini bypass is less complicated than the RNY because of only one connection to the intestines.

2-Year Follow-Up

  • Patients maintained a 67% loss of excess body weight.
  • Nearly 20% of patients had failed to lose at least 50% of their excess weight.
  • Patients maintained a 65% loss of excess body weight.
  • A rather new procedure with less long-term weight loss data
