Question:
Anyone know about Mini Gastic Bypass RNY?

I haven't experienced it but here is some of what I could find about it. This is a PDF document from a surgeon who performs it. Start reading on page 16 and on 56 and it will describe the surgery: http://www.clos.net/PatientManual.pdf . Basically it is a modification of the Gastric Bypass to something that looks almost like a DS except that it works like the gastric Bypass. Like the DS, they make a stomach tube on the side of the stomach instead of making a pouch on the TOP of the stomach like the traditional RNY. INSTEAD of connecting the intestines to the stoma at the bottom of the stomach tube, however, they leave that part of the stomach on the bypassed stomach which they also leave in the body. With the DS, the stomach is removed. Here is where things revert to being the similar to the traditional RNY. The intestine is sewn to the bottom of the stomach tube in the mini Gastric Bypass. In the Traditional RNY it is sewn to the side. It seems that everything ELSE in the procedure remains the same. The big difference in the "Mini Gastric Bypass" is the creation of a stomach tube instead of a traditional pouch. This next statement was taken straight from WikiPedia. I cannot verify the veracity of the statement because of the source but I figured that I should send it along for health concerns. Here is the quote: "Loop Gastric bypass ("Mini-gastric bypass") The first use of the gastric bypass, in 1967, used a loop of small bowel for re-construction, rather than a Y-construction as is prevalent today. Although simpler to create, this approach allowed bile and pancreatic enzymes from the small bowel to enter the esophagus, sometimes causing severe inflammation and ulceration of either the stomach or the lower esophagus. If a leak into the abdomen occurs, this corrosive fluid can cause severe consequences. Numerous studies show the loop reconstruction (Billroth II gastrojejunostomy) works more safely when placed low on the stomach, but can be a disaster when placed adjacent to the esophagus. Thus even today thousands of "loops" are used for general surgical procedures such as ulcer surgery, stomach cancer and injury to the stomach, but bariatric surgeons abandoned use of the construction in the 1970s, when it was recognized that its risk is not justified for weight management. The Mini-Gastric Bypass, which uses the loop reconstruction, has been suggested as an alternative to the Roux en-Y procedure, due to the simplicity of its construction, which reduced the challenge of laparoscopic surgery. It is claimed that construction of a long tubular gastric pouch reduces the risk of inflammatory complications, and renders it as safe as the RNY technique." I hope this helps, Hugh

The Mini Gastric Bypass has been alleged to create a number of problems because of the construction of the limb. Also, a number of surgeons have commented that they find it odd that this program keeps moving from one state to another. For detailed information about any of the bariatric procedures, try visiting the website for the National Institutes of Health (NIH.gov) or the bariatric surgeon's professional association (asbs.org) .
