What is the average pouch size???

I'm two years post-RNY. I recently had an upper endoscopy and found that my pouch volume is 100cc and my stoma diameter is 2.2. Is this normal 2 years post-op? Could this be the reason I never reached an ideal weight and currently have a BMI of 35? Thanks - Nan C

Hi Nan I know that my pouch was 5ozs to start with !! I think thats why I have been able to eat so normally from the beginning  Have no idea what the stoma was though  Susie xx

Hi, Susie.  Hey ... I have this conversion program ... It's giving me numbers.  Here's what it shows.  Nan says her pouch was 100 ML & this converts to 3.52 oz.  This also converts to 104 cm2.  If you plug this into that last article I posted about pouch size ... not good.  My program shows your 5 oz converts to 147.87 ML and 147.87 cm2.  Wow.  This means that ML and CM2 are considered the same.  The article I read said that whatever is measured during the operation, that the pouch actually stretchs fourfold when eating.  If this is true, then Nan's pouch will stretch to approx 14 oz, and yours will stretch to 20 oz.  I don't have any pouch measurements for me.  But since my pouch stretches to hold an olympic size pool, I estimate my pouch size at 30 oz.  lol.  Amy

Hi Nan, I've been looking for info on this too.  Not exactly what I want, but here's one article I found: This says pouch size does matter:  At 12 months, .... . Patients with gastric pouches smaller than 60 cm2 had lost an average of 69.2% of their excess weight. Those with gastric pouches measuring 90 to 120 cm2 lost about 53% of excess weight, and patients with pouches greater than 120 cm2 had lost only about 48% of excess weight (P < .001). That's about a 20% spread in excess weight ... I think this could mean 40 lbs for a 200 lb person.   The article also says ....   Dr. Cohen also commented that it is impossible to precisely measure gastric pouch size and volume. "What may actually matter more than size is gastric pouch emptying," he said. http://www.bariatricsupportcenter.com/modules.php?op=modload&name=News&file=article&sid=259 I don't know how to compare CM2 with CC.   CM2 means cubic centimeters.  CC is a measure of volume.  http://edis.ifas.ufl.edu/AG126 .  I found some other articles that discuss the importance of slow gastric emptying ... & the *difficulty* in maintaining the slow gastric emptying.  Slow empyting is just as important as pouch size ... and right now, scaring is what they are focusing on to keep the stoma stable longer.  It seems that both sclerotherapy & stomaphyX help with that scaring.  Amy

This says: A method for securing permanently slow drainage of the upper pouch seems to be a major problem in gastric surgery for obesity. http://www.ncbi.nlm.nih.gov/sites/entrez?cmd=Retrieve&db=PubMed&lis
