Does gastric dilatation limit the success of sleeve gastrectomy as a sole operation for morbid obesity?

Great news! This research indicates that dilataion (stomach streching) does not necessarily lead to weight gain. In fact, most of the research that I've done (scientifically based) parallels the results of this study.

The reason I've researched this topic is because my capacity has increased after one year post op and sometimes wonder if my stomach is dilated. I don't think my eating behaviors caused dilatation because I can only remember 3-4 times that I ate to the point of discomfort in the past year.

Even if my stomach is dilated, I can still keep the weight off. The surgery did its job by helping me lose over 150 pounds and now I have to put my effort into overdrive during the maintenance phase. For me, this maintenance phase is actually harder than the weight loss phase because it is less structured and I really have to watch my portions because my stomach can hold so much more than before.

The article recommends revision surgery through bypass or duodenal switch if the stomach becomes dilated. However, according to Dr. Weiner (well known bariatric surgeon, search on youtube for his videos), most patients that undergo this revision only lose an average of 15-25 pounds afterward. He often notices (during the revision surgery) that many patients DO NOT even have a dilated stomach.

FYI:

Dilation (stretching) does happen, but mostly to larger sleeves. You are going to have many people tell you that it just can't happen, they are wrong. This seems to have a great deal to do with how much of the fundus is cut out. The remaining fundus can stretch up to four times it's original size. Research shows that about 50% of the ghrelin is still produced in our bodies. I can also attest to the fact that my hunger and cravings are about at 40% compared to before surgery. I've read that most sleeves hold about 2 ounces after surgery but will eventually hold 4-6 ounces. This means that it is normal for the sleeve to enlarge 2-3 times its original size over time, despite not overeating.

Really, what counts is NOT the size of our stomach, but what we put in it. I've seen patients regain weight no matter what their sleeve size. It's interesting to note that I've lost much more weight than those that boast at meetings that they are full after a few tablespoons. Even if your capacity has increased, the key is to stay positive! You can and will be successful!

I would have to agree with the above topic. I have had my sleeve balloon dilated 3 times between Dec 2012 and August 2013 as a last ditch effort (well in addition to two hiatal hernia repairs and a lychees of adhesions procedure) prior to revising to the gastric bypass. I had lost all of my weight 100+ pounds and still then some and have never had one single actual hunger pain. My stomach as my doctor refers to it now is the size of a shrunken walnut and I am on TPN for malnutrition. The balloon dilations however were very welcome procedures as at the time I was unable to keep anything down due to the strictures of the esophagus.

The first study you reference is from Feb of 2006, almost 10 years old. Its sample size is so small, 23, as to be almost meaningless. I would almost discount this one completely due to the age of the study and the limited sample size.

Not saying your basic premise is wrong, but I see no smoking gun here.
