What is the difference between a gastric sleeve and a mini gastric bypass?

What is the difference between a gastric sleeve and a mini gastric bypass?

Don't go mini!: A "mini-gastric bypass" usually refers to a loop gastric bypass. This is a procedure you should NOT have. It will put you at risk for severe bile reflux gastritis. A gastric sleeve is removal of the outer portion of the stomach and is a procedure that is safe and well studied. ...Read more

What is the difference between gastric sleeve and gastric bypass and which surgery is better for weight loss?

What is the difference between gastric sleeve and gastric bypass and which surgery is better for weight loss?

Both are great, but: Both take about one hour, laparoscopic. Usually home the next day. As safe as appendectomy (with experienced surgeon). Weight loss at one year is 80% for bypass and 70% for sleeve. Bypass ideal for bad reflux or bad diabetes. Sleeve has fewer problems with sugar, but mild risk reflux. Talk to your surgeon for more details. ...Read more

What are the pros and cons of a gastric sleeve and a gastric bypass?

Sleeve vs Bypass: You should have a detailed conversation about this with a bariatric surgeon. Briefly, a gastric sleeve is a simpler, shorter operation with less perioperative and nutritional complications. However, the long term results aren't quite as good as bypass. I'm barely scratching the surface of this issue, so again you need to make this decision after and in-depth evaluation with a bariatric surgeon. ...Read more

How is the gastric sleeve and the gastric bypass procedure done?

Small holes : Both bypass and sleeve are laparoscopic (small holes). Both use special staplers which are standard. For the bypass, a pouch is made by dividing the upper stomach. Then the small bowel is divided and the far part is brought up to the pouch. The sleeve uses staplers to make a thinner stomach. Both take about one hour. ...Read more

Do gastric sleeve or gastric bypass work better for losing weight?

Both similar: The sleeve and bypass work in almost all patients. Our experience is to expect about an 80% excess body weight loss with the bypass and 70% with the sleeve. So if you weigh 250 and you are supposed to weigh 150, then you have an excess weight of 100 lbs. Most patients make their decision based on side effects or risks. Both are great. ...Read more

Which is better, to covert a gastric sleeve into a dueodenal switch or to a gastric bypass?

Which is better, to covert a gastric sleeve into a dueodenal switch or to a gastric bypass?

Bypass or switch: Duodenal switch with biliopancreatic diversion (dsbpd) is done far less frequently than gastric bypass in the us. It tends to cause excessive malnutrition which is why gastric bypass (lrygb) is preferred and is the most commonly performed operation. I have had to reverse dsbpd patients who were malnourished and have never had to do that with bypass patients. I would recommend gastric bypass. ...Read more

Which is the most effective: lap band, gastric bypass or gastric sleeve?

Operations: In terms of ultimate weight loss, the bypass would be #1 followed closely by sleeve. The band would be a distant third. For fixing problems like diabetes, high blood pressure, high cholesterol, sleep apnea, the ranking is the same. Sleeves are a good option for someone without diabetes or heartburn. If you have those problems or have a bmi over 50, the bypass is a better option. ...Read more

Can you tell me is gastric sleeve safer or gastric bypass surgery is safer?

Can you tell me is gastric sleeve safer or gastric bypass surgery is safer?

Sleeve gastrectomy: That's a common misconception by patients. The gastric bypass is a more complicated operation than a sleeve, but the risk of a leak is the same for either operation. In addition, if a leak occurs, it is much harder to control in a sleeve than in a bypass. There are many other pros/cons for each, but the bottom line is that the risk is about equal. For diabetes and heartburn/reflux, bypass is best. ...Read more

Since the gastric sleeve can cause complication with a sarcoidosis patient. Is the gastric bypass better to have done with sarcoidosis?

Since the gastric sleeve can cause complication with a sarcoidosis patient. Is the gastric bypass better to have done with sarcoidosis?

sleeve ; sarcoidosis: Neither one (bypass or sleeve) is better than the other with respect to sarcoidosis. Studies have shown that people on immunosuppressive therapy can safely undergo either operation. I would just decide which operation is best for you. In a healthy ; moderately obese person, either operation is fine. If you have gerd, diabetes, or have a bmi over 50, bypass is preferred. ...Read more
