Types of weight-loss surgery
Types of procedures
A surgeon creates small gastric pouch, limiting food intake and it's absorption. Results of this procedure are not visible only in significant reduction of body mass but also in reduction and sometimes even in complete recovery from some of concomitant diseases. Even glucose metabolism is different after the bypass. Sugar holds no allure for patients even if they were obsessed with it.
A surgeon surgically creates small gastric pouch at the top of the stomach, separating it completely from the rest of the stomach.
Pouch is quickly filled with food and therefore our brains quickly receive the information that we are fed, because nervous receptors, which are responsible for the sensation of satiety, are located in this very part of the stomach. The surgeon connects the pouch with a lower part of the intestine causing the body to absorb fewer nutrients and therefore fewer calories. The food is digested more slowly and is later mixed with stomach acid, bile and pancreatic juice, hence part of food remain undigested and is excreted from the body.
Results of this procedure are visible on three levels:
- Limiting – because of small volume of a pouch, amount of food that a person can consume in one serving is limited;
- Malabsorption – because of small volume of a pouch, amount of food that body absorbs is lowered;
- Changed dietary habits – diminished crave for food one should stop using anyway (concentrated sugar, fats etc.).
After such surgery we should pay special attention to the diet. Like a gastric band, this procedure also significantly lowers food intake. Difference between gastric band and gastric bypass is in digestion as such, and in absorption of nutrients from the food. When gastric bypass is performed, we take upper and lower part of the intestine out from the digestion process where body absorbs important minerals, vitamins and other nutrients, so after the procedure we have to pay special attention to the structure of our diet. Dietetic support and expert's advices are essential when deciding about food and preparing optimal diet plan after the gastric bypass.
European study, which explored the effect of gastric bypass on obesity-related comorbidities on a sample of 466 patients, has shown exceptionally good results:
|Complete recovery (%)||Improved condition (%)|
|High blood pressure||67.80||24.40|
|Sleep apnea (Obstructive Sleep Apnea Syndrome)||86.00||13.30|
|Lower back pain||49.00||31.20|
Weight-loss surgery team have been carrying out weight-loss operations since 2007. Average weight loss is 35 kg after the first year and 45 kg after three years (patients that undergo gastric bypass are usually heavier so they lose more weight).
Gastric banding (SAGB – Swedish adjustable gastric banding)
Main characteristic of this procedure, besides the possibility to remove a band and restore the stomach back to its original condition, is possibility to regulate flow of the food which conduce to very good results in loosing excess weight.
Gastric band is a device that surgeon place around the top portion of the stomach. Doing this he creates a stenosis that works like an hourglass. In this upper part of the stomach are nervous receptors that send a message to the brains that the stomach is full. Since newly made pouch has small volume, it is quickly full which causes a sensation of satiety. Food then slowly pass through the stenosis to the rest of the stomach and makes that sensation of satiety stays longer.
Insertion of a band is minimal intervention in the natural body functions and this is why digestion and food absorption still remain natural after the procedure. Four weeks after the procedure a surgeon checks the band and if it is necessary he decides to inflate it. Using special tube, he inflates special liquid that expands the band and narrows the stenosis through which the food is passing. Also during following checkups surgeon checks condition of the band and decides whether to broaden or to narrow the stenosis, depending on the situation. Gastric band could be removed if that is necessary or wanted and the stomach will gradually get it's original form. Insertion of a gastric band is done via laparoscopic surgery (it is conducted through small incisions) and this is why recovery after the surgery is quick. In most of the cases recovery in a hospital takes 1 to 4 days and after that one month at home
The average loss of excess body weight after inserting a gastric band is to 0.5 kg per week, but a reduction of body weight at the end of the course depends on each individual. The effects of the insertion of a gastric band are not visible only to the loss of excess weight, improved physical well-being and self-image, but also to reduce or even cure many concomitant diseases:
|Complete recovery (%)||Improved condition (%)|
|High blood pressure||58||42||Diabetes mellitus||75||8|
|Sleep apnea (Obstructive Sleep Apnea Syndrome)||75||25|
|Dyspnea (shortness of breath)||85||12|
|Gastroesophageal reflux disease (GERD)||79||11|
Dr. Breznikar and Dr.Kunst weight-loss surgery team has performed more than 320 insertions of a gastric band since 2005. The average weight loss is 24 kg after the first year, and 35 kg after three years.
Other types of gastric procedures
Dr. Breznikar and Dr. Kunst weight-loss surgery team besides gastric bypass in some rare occasions perform longitudinal resection of the stomach (commonly referred to as "sleeve gastrectomy"), gastric plication (suturing of the stomach, stomach reduction), and insertion of a gastric band.
Gastric plication and gastric resection
Dr. Breznikar and Dr. Kunst weight-loss surgery team besides insertion of a gastric band and gastric bypass in some rare occasions perform longitudinal resection (sleeve, gastrectomy) and gastric plication (suturing of the stomach, stomach reduction).
With longitudinal gastric resection a surgeon removes larger section of the stomach. Upper part of the stomach and connection to the intestine remains intact whereas volume of the stomach is significantly reduced (up to 85%). Effects of a surgery are visible to substantially reduced amount of food eaten in one meal, and to a lesser extent even to changes in digestion and absorption due to the removed part of the stomach.
Changes in the digestive processes after the gastric bypass are not so distinct but there is still a need to take a good look at the eating habits, so your body would not lack any of minerals, vitamins and other important nutrients.
Dr. Breznikar and Dr. Kunst weight-loss surgical team has performed 40 longitudinal resections since 2006. The average weight loss is similar to that at the beginning of a gastric bypass, and after a few years it increases again.
Gastric plication is a special type of a resection of the stomach, where the surgeon doesn't cut but only sew a considerable part of the stomach. This is why gastric plication compared to longitudinal gastric resection does not change the natural flow of digestion and absorption.
Dr. Breznikar and Dr. Kunst weight-loss surgery team has performed over 35 gastric plications.
