Mini Gastric Bypass with Prague Beauty

Mini Gastric Bypass

In recent years, a surgical technique known as Mini Gastric Bypass or single-anastomosis gastric bypass has been developed. Its frequency of performance has increased considerably in the current decade, nowadays Dr Vrany carries out Mini Gastric Bypass as a primary bariatric surgery.


Obese class II, i.e. BMI of 35 and higher. Age between 18 and 65 years.


Mini Gastric Bypass (MGB) is a minimally invasive surgery carried out laparoscopically under general anaesthetic. A small incision (less than 1/2 inch, 1 cm) is made near the belly button. Carbon dioxide (a gas that occurs naturally in the body) is introduced into the abdomen to create a work space for the surgeon. Then a small laparoscopic camera is placed through the incision into the abdomen. The camera sends a picture of the stomach and abdominal cavity to a video monitor. It gives the surgeon a good view of the key structures in the abdominal cavity. A few additional, small incisions are made in the abdomen. The surgeon watches the video monitor and works through these small incisions using instruments with long handles to complete the procedure.

Then a surgeon first reduces the size of the "working" stomach by separating a tube-like pouch of the stomach from the rest of the stomach. This tubular gastric pouch is then connected (anastomosed) to the intestine, bypassing up to 200cm of the upper part of the intestine. This technique differs from the traditional Roux-en-Y Bypass (RYGB) which requires two connections (anastomoses). Compare to the Sleeve Gastrectomy where the part of the stomach is removed, therefore it is not a reversible surgery, Mini Gastric Bypass is reversible and has a quicker weight loss profile.

Some nutrients (for example an iron, a vitamin B12, etc.) are absorbed in the duodenum, which is the part of the small intestine that is bypassed after an MGB. As the result, your body won't be able to absorb their adequate amounts any longer and you will have to use supplements for the entire life.


  • Considerable improvement or even remission of co-morbidities (especially Diabetes type 2, Sleep Apnea)
  • Only one anastomosis - in theory, less chance of a complication, while a Roux-en-Y bypass has two and also MGB is less invasive
  • Better weight loss and a higher diabetes resolution rate compare to a Roux-en-Y bypass
  • Reversible
  • MGB is an effective, relatively low-risk, and low-failure bariatric procedure. In addition, it can be easily revised, converted, or reversed
  • Overall, the MGB is very safe initially and in the long-term. It has reliable weight loss and complications similar to other forms of gastric bypass


  • Very high survival rate (close to 100%). Complications are similar to a Roux-en-Y bypass surgery
  • Minor complications include hernias at the surgical site, ulcers, and minor incision infections
  • Major complications typically are staple line leaks, pulmonary embolisms, strictures, among other risks - general anaesthesia risks exist, as with any procedure

5 most prevalent but still relatively uncommon:

  • Marginal Ulcers (~3% of patients)
  • Gastrointestinal bleeding (~3% of patients)
  • Wound Infection (~3% of patients)
  • Gastrointestinal Leak (~1% of patients)
  • Bile Reflux Esophagitis (< 1% of patient)

As with any major surgery, mini gastric bypass poses potential health risks or unforeseen, unknown or adverse reactions, both in the short-term and long-term.

Risks associated with mini gastric bypass surgery can include:

  • Excessive bleeding
  • The need to convert to an open procedure
  • Perforation
  • Injury to another organ
  • Infection
  • Adverse reactions to anaesthesia
  • Blood clots
  • Lung or breathing problems
  • Leaks from staple line

Longer-term risks and complications of mini gastric bypass surgery can include:

  • Gastrointestinal obstruction
  • Hernias
  • Gastroesophageal reflux
  • Billiary reflux
  • Stomach kinking
  • Strictures
  • Low blood sugar (hypoglycemia)
  • Malnutrition
  • Vomiting
  • Vitamin deficiency and their consequences

Dumping syndrome:

When the Gastric Bypass patient eats a sugary food, the sugar passes rapidly into the bowel, where it gives rise to a physiological reaction called dumping syndrome. The body will flood the intestines in an attempt to dilute the sugars. An affected person may feel their heart beating rapidly and forcefully, break into a cold sweat, get a feeling of butterflies in the stomach, and may have a "sky is falling" type of anxiety. He/she usually has to lie down, and could be very uncomfortable for about 30 to 45 minutes. Diarrhea may then follow.

Nutritional deficiencies:

Inadequate absorption of calcium, iron, zinc, Vitamin B1, Vitamin B12, Vitam A, and proteins. Calcium supplements, iron supplements, protein supplements, multi-vitamins and B12 (cyanocobalamin) supplements are all very important to the post-operative bypass patient.

Occasionally, a female patient develops severe anemia, even with supplements, and must be treated with parenteral iron. The signs of iron deficiency are the following: brittle nails, an inflamed tongue, constipation, depression, headaches, fatigue, and mouth lesions.

Achlorhydria is a condition where there is not enough acid in stomach. Patients can develop an overgrowth of bacteria as a result of the low acidity levels in the stomach.

Alcohol metabolism:

Patients who have undergone mini gastric bypass surgery will have a lower tolerance than people who have not gone through the surgery. It will also take a mini gastric bypass patient longer to return to a sober level after drinking alcohol than a person who has consumed alcohol that has not had the surgery.


It is a compulsive tendency to eat substances other than normal food. Some examples would be people eating paper, clay, plaster, ashes, or ice. The patient is eating these substances mainly due to the iron deficiencies that occurred after mini gastric bypass surgery.

Very rarely, complications of gastric bypass can be fatal. Fewer than 10 out of 1000 people die after mini gastric bypass. There is a quoted 0.5% risk of dying during, or as a result of the Gastric Bypass operation, mainly due to the risk of developing blood clots, haemorrhage or leaks, so we take great care in minimising this risk with pre-op preparation for surgery and expert care.

Please contact your physician or our Hot Line +420 602 166 757 immediately if you have any concern regarding possible complications.


It is highly recommended to patients after bariatric surgery to arrange a blood test four times a year to early discover any vitamin deficiency.

Both groups, i.e. sleeve or bypass patients, please take particular attention to Thiamine (vitamin B1) as such deficiency could occur in up to 49% of patients as a result of bypass of the jejunum, where it is primarily absorbed, or in the presence of impaired nutritional intake from persistent, severe vomiting.

The early symptoms of Thiamine deficiency are nausea and constipation, but it could worsen up and lead to neurological and psychiatric complications known as Wernicke-Korsakoff syndrome. Proper supplementation is therefore essential to stay on the safe side.

Wernicke–Korsakoff syndrome on Wikipedia


Mini Gastric Bypass is usually not recommended for people with any of the following:

  • If the surgery or treatment represents an unreasonable risk to the patient
  • Inflammatory diseases of the gastrointestinal tract such as ulcers, oesophagitis or Crohn’s disease
  • Gastric or eosophageal varices
  • Hiatus hernia
  • Severe cardiopulmonary diseases or other conditions which may make them poor surgical candidates in general
  • Dependency on alcohol or drugs
  • People with severe learning or cognitive disabilities or emotionally unstable people


  • Nausea
  • vomiting
  • pain
  • cramps
  • diarrhea
  • constipation
