Mini Gastric Bypass

What is The Mini Gastric Bypass Surgery?

Mini Gastric Bypass Surgery, also known by One Anastomosis Gastric Bypass or by MGB, is a common Bariatric Surgery. Mini Gastric Bypass, like other Bariatric Surgeries, aims to trigger weight loss through modifications to the digestive system that restrict the absorption of the nutrients. The stomach is made into a small tube, and the effective bowels are shortened.

After Mini Gastric Bypass Surgery, consumed food will go through the new tube shaped stomach and then go into the newly attached part of the small intestine, bypassing 6.6 to 8 feet (200 - 250 cm) of the small intestine.

Mini Gastric Bypass is done Laporoscipally, which shortens the recovery period and prevents permanent surgery scars.

Mini Gastric Bypass is named after the Roux En Y Gastric Bypass, but has only a single anastomosis instead and combines properties of the Gastric Sleeve and Gastric Bypass. Mini Gastric Bypass is frequently preferred over Gastric Bypass due to its successful results and being the shorter, as well as, cheaper method.

Why is Mini Gastric Bypass Surgery Performed?

Mini Gastric Bypass is used as a primary weight loss procedure, and used to treat obesity and obesity-related medical conditions. Mini Gastric Bypass is also the preferred revisional surgery for patients who were unsuccessful with Gastric Band or Gastric Sleeve.

Mini Gastric Bypass alleviates gastroesophageal reflux, heart diseases, high blood pressure, high cholesterol, sleep apnea, and type 2 diabetes, but is not the suitable option for patients who have acid reflux as Mini Gastric Bypass will exacerbate it.

Surgical methods, like Mini Gastric Bypass, are often recommended if the patient is morbidly obese to such a degree that even dieting and exercises are not enough to help the patient lose weight.

Mini Gastric Bypass, like Gastric Sleeve, is performed laparoscopically, i.e. using small keyholes instead of opening up the abdomen.

What are The Conditions Of Mini Gastric Bypass Surgery?

The final decision on if a patient qualifies for Mini Gastric Bypass or if Mini Gastric Bypass is recommended is made by our Bariatric Team, here are some of the qualifying criteria that our Bariatric Team uses for Mini Gastric Bypass:

  • A Body Mass Index, BMI, of at least 35 is required, or having an obesity related condition with a BMI of 30.
  • Must not have tested positive for Covid within the month before surgery.
  • Must not have an active infection at the time of the surgery.
  • Must not have Acid Reflux caused by a hiatal hernia.
  • Chronic diseases, such as type 2 diabetes, hypertension disease etc, might require additional testing before arriving in Turkey.
  • Patients should stop smoking and alcohol at least 6 months before surgery.

What Are The Things To Be Considered Before Mini Gastric Bypass?

After a patient qualifies for the Mini Gastric Bypass, their Patient Coordinator, along with a treatment schedule, will provide the patient with a Liver Fat Reducing Diet that should be followed before arriving at the hospital. The patient should not consume any food or liquid 12 hours before the surgery in order to make sure the stomach is empty before surgery. The following dietary and medicinal restrictions have to be followed before the surgery as well:

  • Usage of vitamin K should be stopped 30 days before surgery as it is an anticoagulant, i.e. blood thinner, and increases the rate of complications associated with internal bleeding.
  • Oral contraceptives and any other contraceptives that have estrogen or progesterone, like coils, HRT patches, or birth control implants, must be stopped or taken off 30 days before the surgery as they increase the rate of complications arising from blood clots. Hormonal and oral contraceptives can be used 30 days after surgery. Non-hormonal implants are safe and recommended if considering a mini gastric bypass.
  • Smoking should be avoided starting a week before surgery until three weeks after surgery. Smoking causes the veins to constrict and limits blood circulation, potentially causing complications such as leakage.
  • Alcohol consumption should preferably be avoided in the last 3 months leading up to the surgery. Alcohol consumption a week before surgery should especially be avoided as it will increase the burden on the liver and might cause complications with anesthesia.
  • The patient will have a consultation with an internal diseases specialist, radiologist, anesthesiologist, and a general surgeon before the surgery.
  • Preoperative tests at the hospital will include full abdominal ultrasound, chest x-ray, breath functioning test, electrocardiogram, endoscopic investigation of the stomach, and full blood test as pre operation test and exams.

What Are The Things To Be Considered During Mini Gastric Bypass?

The surgery takes about 60 to 90 minutes to complete. Like the Gastric Bypass, the Mini Gastric Bypass surgery is also a two - part procedure that separates approximately 25% of the stomach from the rest of the stomach. A pouch is created from the smaller part of the stomach, and is then joined to the small intestine with an anastomosis. After surgery, the majority of the stomach and approximately 6.6 - 8 feet (200 to 250 cm) of the small intestine are bypassed which means they are no longer involved in the digestion or absorption of the food eaten.

The surgery is performed under general anesthesia. The surgeon makes 4 - 6 keyhole cuts on certain points of the patient's abdomen. A camera and surgical instruments are inserted through these keyholes. The camera is connected to a video monitor in the surgery room that allows the surgeon to view the inside of the abdomen for the operation.

The stomach is divided with a laparoscopic stapler and a smaller tube shaped stomach is formed. Remainder of the stomach is no longer attached to the esophagus and will no longer help with the digestion of the food. The surgeon will then bypass 6.6 to 8 feet of the intestines and the remainder is then attached to the new stomach. As a result, the food that passes from the small stomach into the small intestines is met with the digestive juices that have been produced in the remaining bigger stomach.

What Are The Things To Be Considered After Mini Gastric Bypass?

Mini Gastric Bypass postoperative prescriptions given to the patients will include blood thinner injections and stomach protectors. The medicine provided will include antibiotics and painkillers that should be used if needed. A Booking Surgery dietician will provide a diet list for each patient and will provide additional support if needed. The initial dietary restrictions post surgery will be as follows:

  • The patients will only consume liquids for the first 3 weeks following surgery. Also called the liquid stage, patients are advised to consume protein shakes, soups, herbal tea, etc.
  • The patients are advised to consume puree and liquid foods for the following 3 weeks. Also called the puree stage, patients are recommended to increase their diet by eating mash and blended foods.
  • After 6 weeks of liquid and puree stage, the patients can start consuming solid foods. After Mini Gastric Bypass surgery, patients should never eat solid and liquid foods at the same time.
  • Additionally, patients should avoid caffeinated or carbonated drinks for 3 months following surgery, but decaffeinated coffee can be safely consumed 10 days after surgery.
  • Patients should also avoid smoking, alcohol, and any recreational drugs for at least 3 weeks following surgery.

Post surgery, some physical activities should be avoided as well:

  • Patients can go back to work 2 weeks after getting home if it's not a physically strenuous job.
  • Patients should avoid strenuous activity and sexual intercourse for the first month following surgery.
  • Patients should walk frequently and should not do any heavy lifting more than 5 KG for the first month following surgery and not more than 10 KG for the first 3 months after surgery.
  • Patients can start exercising to help the weight loss process 2 months after the surgery.

Additionally, the surgical stitches will dissolve on their own, but if they do not, patients should take an appointment from their GP to get them removed.

What are the Risks of Mini Gastric Bypass Surgery?

Mini Gastric Bypass Surgery, while being shorter than Gastric Bypass and being done Laporoscipally, has some risks associated with it like any major surgery. These risk include:

  • Increased risk of acid reflux
  • Increased risk of bile reflux
  • Bleeding
  • Infections
  • Intestinal Obstruction
  • Leakage
  • General anesthesia complications
  • Blood clots
  • Deep vein thrombosis

Blood thinners and compression socks provided after surgery lower the likelihood of blood clots and deep vein thrombosis.

These risks most likely show up within the first month after surgery.

What are the Long-Term Complications of Mini Gastric Bypass?

The long-term complications of Mini Gastric Bypass Surgery can be explained as follows:

  • Stomach Ulcers
  • Incisional Hernia
  • Malnutrition
  • Gallstones
  • Dumping Syndrome

Malnutrition:

Malnutrition occurs when the body is deprived of vitamins, minerals and other nutrients needed to maintain healthy tissue and organ function.

The long term side effects of Gastric Bypass (Roux en Y) Surgery, as a result of malnutrition, include:

  • Vomiting
  • Pain
  • Fatigue
  • Dry Skin
  • Mood Changes
  • Hair Loss
  • Hernias
  • Gastroesophageal reflux
  • Hypoglycemia

Gallstones:

During the rapid weight loss after Gastric Bypass surgery, approximately the first 6 months, gallstone formation increases by up to 20%.

Dumping syndrome:

Dumping syndrome is caused by the food and liquids in the stomach reaching the small intestine in a short time after Mini Gastric Bypass Surgery.

What To Do When Weight Loss Surgery Doesn't Work?

If Mini Gastric Bypass surgery is performed correctly by a certified surgeon, the patient will lose a significant portion of their excess body weight. In some cases, patients might experience severe acid reflux after mini gastric bypass which might require a revision into a Roux En Y Gastric Bypass. A revision from mini gastric bypass to roux en y gastric bypass might be considered.

The surgery is considered a failure if the patient regains the weight in a few years. Going back to old eating habits by forcibly overeating or frequently drinking carbonated drinks may cause the stomach to enlarge, therefore allowing weight regain.

Poor weight loss often leads to consideration of a revision surgery. In such a case, a revision from Mini Gastric Bypass to Gastric Bypass might be performed.

What Are the Advantages Of Mini Gastric Bypass?

Mini Gastric Bypass has many advantages which can be listed as follows:

  • It is performed in a modified manner that involves less intestinal rerouting and a shorter overall procedure time.
  • Risk of internal hernia is lower than due to Roux en Y Gastric Bypass.
  • Mini Gastric Bypass is reversible as parts of the old stomach are not removed from the abdomen.
  • Alleviates obesity-related health problems such as type 2 diabetes, hypertension, sleep apnea, and acid reflux.
  • Within the first year after the surgery, patients lose 75% of their excess body weight, and 80% - 90% of their excess body weight within the first two years.
  • Less likely to gain back excess weight, unlike yo-yo dieting, the weight loss is usually for life.
  • Produces positive changes in intestinal hormones that reduce appetite and increase the feeling of fullness.
  • Decrease in excess weight alleviates the pressure on the knees and joints, increasing the recovery rate of osteoarthritis up to 85%.
  • It is performed in a modified manner that involves less intestinal rerouting and a shorter overall procedure time.

What Are the Disadvantages of Mini Gastric Bypass?

While Mini Gastric Bypass Surgery has many advantages, it does possess some disadvantages that have to be considered before going through with the surgery. Some of the disadvantages include:

  • Compared to other stomach reduction operations, the possibility of complications is higher since the operation involves a wider portion of the digestive system.
  • Although it is rare, as Mini Gastric Bypass reduces absorption, vitamin deficiency may occur.
  • Bariatric vitamin supplements have to be taken permanently after the operation.
  • Endoscopy becomes harder to perform on the patient after the Mini Gastric Bypass surgery, but is still possible.
  • There are chances of bile reflux gastritis. This is considering that mini-gastric bypass surgery does not divert the bile and digestive enzymes from the stomach. Therefore, there are chances of a condition that can be hard to treat.
  • Even though the Mini Gastric Bypass Surgery is less invasive, it still carries potential infection risks. Leakage or infection among staples connecting the stomach and intestines is also possible.
  • There is a possibility of complications similar to Roux-en-Y gastric surgery. The most common being surgical site hernias, ulcers, and other minor infections.
  • Has short and long term risks associated with it.

 

Which is better: gastric bypass or mini bypass?

Both Gastric Bypass and Mini Gastric Bypass surgeries are performed laparoscopically. Two anastomoses are made during Gastric Bypass and a single anastomosis is made during Mini Gastric Bypass. Mini Gastric Bypass is the shorter surgery, but provides a similar weight loss. But, while Gastric Bypass completely treats Acid Reflux, MIni Gastric Bypass often exacerbates it. Neither can be considered better, but offer a trade off between complexity and additional side effects.

How much weight can you lose with a mini gastric bypass?

The patients, on average, lose 80% of their excess body weight within a year, their weight loss slows down afterward and stabilizes near their target weight.

The rate and amount of weight loss vary greatly from person to person, and according to lifestyle choices and eating habits of the patient as well as their gender and age.

How big is your stomach after a mini bypass?

In mini gastric bypass surgery, a gastric tube is first created, similar to sleeve gastrectomy surgery, but smaller in size. Then, the first 150-200 cm of the small intestine is disabled and the small intestine is connected to the lower end of the newly formed tube stomach.

How long does it take the stomach to heal after a mini gastric bypass?

Patients who undergo Mini Gastric Bypass surgery usually stay in the hospital for 4 more days.

While it is not possible to eat solid foods immediately after the operation, liquid nutrients are safe to consume. Patients should not lift heavy weights after the surgery for at least a month and can return to work 10 days after going back home.
 

Who is a candidate for a mini gastric bypass?

Mini Gastric Bypass surgery is a common Bariatric Surgery and is performed to patients who have Body Mass Index, BMI, of at least 30. Obesity related illnesses, such as high cholesterol or high blood pressure, should also be a motivation to have a Mini Gastric Bypass. Mini Gastric Bypass is also a good option for patients who have previously had a Gastric Band or a Sleeve Gastrectomy but have failed to lose weight.

Can you put weight back on after a mini bypass?

As with other bariatric surgery methods, there is no guarantee that weight loss will be permanent after Mini Gastric Bypass Surgery. Having an active lifestyle, and keeping a healthy diet will make weight regain less likely.

Can you drink alcohol after a mini gastric bypass?

It is not recommended to consume any alcohol for the first 6 months following the Mini Gastric Bypass surgery. Additionally, alcohol is high in calories and low in nutrition, therefore is not recommended for anyone trying to lose weight.

What is Body Mass Index (BMI)?

Body mass index (BMI) or height-weight index is a calculation method that shows the estimated fat content of a person's body. This method is based on the person's height to weight ratio. According to the result of the index, the proximity and distance of the person's current weight to his/her ideal weight can be calculated

How is Body Mass Index Calculated?

Body mass index is calculated by dividing the body weight by the square of the height (kg/m⊃2;).

Results below 18.5 kg/m⊃2;: Below ideal weight

Results between 18.5 kg/m⊃2; and 24.9 kg/m⊃2;: Ideal weight

Results between 25 kg/m⊃2; and 29, 9 kg/m⊃2;: Above ideal weight

Results between 30 kg/m⊃2; and 39, 9 kg/m⊃2;: Above ideal weight (obese)

Results above 40 kg/m⊃2;: Above ideal weight (morbidly obese)

 

What Do Body Mass Index Results Mean?

Body mass index calculation does not include factors such as fat ratio, body type, fat and muscle tissue. For this reason, experts obtain more detailed information about the person's weight problem by measuring the metabolic rate and detailed body analysis, in addition to measuring the body mass index and waist circumference in calculating the ideal weight. The fact that the person is above or below the ideal weight should be evaluated by the physician together with other factors. Action should be taken together with the physician to eliminate existing health problems and prevent possible health problems.

In men, if the waist circumference exceeds 94 cm, it is considered an increased risk, and if it exceeds 102 cm, it is considered high risk. In women, this ratio is considered increased risk if it exceeds 80 cm and high risk if it exceeds 88 cm.

Obesity Calculation with Detailed Body Mass Index

In calculating obesity with detailed body mass index, it can be learned whether the weight, body fat percentage and waist circumference are within normal values, taking into account age and gender.

First of all, it is very important for the diagnosis and treatment of obesity to know where the fat tissue accumulates in the body. The way fat tissue accumulates in the body can be divided into two as apple type and pear type.

In apple type obesity, fat accumulates around the belly. In pear type obesity, it is observed to accumulate in the hips and thighs. However, the fat accumulated around the navel is considered to be more dangerous and has a higher risk of heart disease than the fat accumulated in the hips and thighs.

Mags reviewed Excellent service with bookingsurgery.com

I used bookingsurgery.com for procedures at medistanbul with Dr Yalcin. From getting in contact to having the procedures the care has been second to none. The coordinators and interpreters have made everything seamless, many thanks to Lily, Morgan and Frank for all your help. The nursing staff are always at the end of the buzzer and the cleaners are popping in regularly with a smile and a mop. The food not so amazing but I didn’t come here for a gourmet experience! Would have no hesitation in returning or recommending this company.

I had a boob augmentation (implant under the muscle) this week at medistanbul with booking surgery and I arranged the booking with David a co-ordinater who was nothing short of brilliant and even came to see me post surgery to make sure things were all okay. Dr Yalcin did my surgery, post surgery care and took out my drains and was a lovely bloke who achieved everything I asked for and more. Lily - my interpreter helped me the whole time and even got me English tea and coffee into the hospital, she helped me with my payments and general healthcare. All of the nurses were so caring, considerate and made me feel comfortable. On my leaving day, I felt reassured and ready to leave. I will definitely be returning for more surgery in the future :)

I was given all the information about surgeons, pictures of there plastic surgery work and the decision was mine. I chose Dr Yalçin🩺 Upon arrival in Istanbul Sunday 2nd June I was picked up and it all began. Loads of staff a lot of different faces and always an translators at all times. I meet Dr Yalçin Monday 8am he done his drawings in me and I went down about 8.30am. Pain was manageable, nurses would come when you buzzed. Dr visited very day to check on all my wounds. Honestly just so incredibly grateful to Dr Yalçin and his team, 20yrs I waited and you made all my dreams come true in 1 day. Plus he has the loveliest smile you will see in your day. I had a few peeks and the wounds and stitching look phenomenal. If only Dr Yalçin new how much is amazing work literally changes people's lives. Thank you so much ;-) Big shout out to Lily and the whole translators and Booking Surgery Team. Would 💯 recommend to anyone asking and i know where to come if I'm ever looking for something else in future (Maybe thigh n arms we will see)!

Jo Davis reviewed Breast uplift with implant…

I had a breast uplift with implant through BookingSurgery.Com on 3rd June 2024, and my partner had dental work done by them too whilst we were there. My partner and I used this company through personal recommendation from someone he knew who had used them for weight loss surgery and then for plastics/reconstructive surgery after. After hearing "horror stories" about surgeries abroad, it was important to get it right. I initially contacted BookingSurgery.Com through their website and a coordinator named Robert Campbell followed up my enquiry through WhatsApp message. After discussion about breast augmentation, Robert consulted with the surgery team and came back to me with a recommendations and quote from two surgeons. The recommendation was breast uplift with implant. I was very happy that the quote included transfers from airport to hospital, the surgery and medications, three meals a day for myself and a companion and their overnight stay too. To secure the price I only had to pay a £100 deposit and the outstanding balance didn't need to be paid until my surgery date. Robert asked me when I'd like to come for my surgery, I gave him an ideal date and he secured it. Robert was a brilliant coordinator, very polite and responded to my queries in good time, liaised with the surgeon and informed me accordingly at all times. When it came to the time for us to come to Turkey, the person who met us off the plane (Gurçan) was very friendly, helpful and a good driver. The cab had WiFi we could connect to which was great. (We also had the same driver who took us back to the airport for our return flight.) We arrived at the hospital and were met by a very happy, welcoming friendly translator called Stella who showed us to our room and explained what would happen next (as you have your pre-op on the day of arrival.) The consent form was very transparent on the surgery I was receiving, what to expect and any risks associated with the procedure which meant I could make an informed choice. The hospital we were at was called Yasam and the rooms, corridors etc were very clean and nice. The nurses were friendly and the care received was of a high quality. The cleaners were friendly and polite too. We had our own bathroom and smart tv and were comfortable. My partner's coordinator, Nora, arranged affordable transfers using the BookingSurgery.Com drivers to take him to the dental hospital in the city where he had his prep work and crowns fitted. The following day was surgery day and I met with my surgeon (Dr Nebil) and the anaesthetist. Dr Nebil really listened to what I was hoping to achieve and very informative. Before going down for surgery, the nurse gave me a sedative as general procedure. I was very happy with the results of my surgery and glad that I followed Dr Nebil's advice of implant with the uplift. His work is amazing! The nurses looked after me very well and the Dr visits you every single day to check on your progress and to answer any questions. There's always a translator on site which makes communication no issue. Pain relief and medications are all included in the care during hospital and when you go home. You receive an information pack to go home with which gives you very detailed advice on how to care for yourself following surgery including when you can resume normal activities such as driving, exercise, sunbathing etc. There are fit to fly letters, medication list with instructions on how to use, all tests taken prior to surgery, and after with the results, and a detailed write up on the surgery process, what was performed and how. I have photocopies of the boxes that my implants came in with serial numbers, details etc, and also contact info for a post op coordinator should there be any issues or if my recovery isn't as explained in the letter. This is very reassuring that BookingSurgery.Com are still looking after me once home. There were 4 translators in the hospital who were all helpful but I want to give a special mention to Stella and Oscar who I felt were more like friends. I met some lovely people on my ward who were all with BookingSurgery.Com for various procedures and having them to talk with definitely helped in terms of company and what to expect in regards of recovery etc. Before leaving Yasam hospital, I was very happy that I was able to have a photo taken with my Dr and translators, and am so happy that I chose to use BookingSurgery.Com

This is my 2nd time with Bookingsurgery. Both bariatric and plastics. The nurses and surgeons and translators are amazing. The care they provide is so much better than the UK. You want for nothing, I’ve need help this time and they are with you in minutes. I wouldn’t hesitate to come back again. Dr Nabil, Nadia, Oscar and the whole team thank you for changing my life
