DS vs RNY common Channel length
Read the studies on DS and that the research is based on 100cc.
From my understanding the longer the length the more nutritional issues you have.
I am wanting my surgeon to do the DS with a common channel about the same as the RNY, but don't know if that is possible.
Will probably cross post this in the RNY and DS forums as well... hope that is ok. :)
common channel is the length of intestine where food and digestive juices mix together.
Average cc length for ds .. I have seen anywhere from 75 to 150.
In the rny they only bypass 100 to 150 of the intestine.
So... IF total intestinal lenght is around 600...
then the cc in the rny would be around 450-500
BUT there is a distal rny with a common channel of I believe 150-250.
Loosing Sally and VItalady both have a distal rny and are successful!
I am by far not an expert, and these are just off the top of my head, keep doing your research!
Good Luck!

Proximal RNY |
Distal RNY |
Duodenal Switch |
Scopinaro's BPD |

Stomach size |
30 cc | 30 cc | 120-180 cc | 250 cc |
Common channel |
500 cm | 100-400cm | 100 cm | 50-100 cm |
Common channel in inches |
200 inches | 40 to 160 inches | 40 inches | 20-40 inches |
Biliopancreatic limb length in cm (not including duodenum) |
100 cm or less than 15% of the distance between the Ligament of Trietz and the colon | For some insurance purposes, anything longer than 100 cm bypassed is considered a distal bypass | 400 cm or about 60% of the distance between the ligament of Trietz and the colon | 400 cm or about 60% of the distance between the ligament of Trietz and the colon |
So, if he goes 250 that would be a good/safe distance? Right????

Unfortunately a condition I was born with will not allow me to have either the Sleeve or the DS.
Seems that I don't have a functioning pyloris because it was "disabled" when I was 4 weeks old because of pyloric stenosis: Pyloric stenosis.
So it does not matter what I think, or what I want, because my guts are already damaged from the band and the pyloromyotomy. So the RNY is the only thing I can do past the band.
Dr. Barker is the best doctor ever. He caught that and explained it to me in detail. He patiently spoke with me regarding the DS, and he listened to what I wanted done, but when he saw the pyloric stenosis surgery he put a stop to that conversation very quickly. No one would touch it because of the liver and how the pyloris heals to it and the closeness of that to the pancreas. (???)
Basically my only choices are the band or RNy because it deals with the upper part of the stomach.
Totally stinks. I don't want the RNy. I am afraid of it. But he said that it will be a more agressive bypass because of my BMI. But not quite a distal. Good Grief. Guess I will be an RNY'er whether I want to be or not.
Well, 2 people, actually......
1) Viatalady & 2) Melting Mama a.k.a. Beth
I'll look up info & link it here for you.
These 2 ladies are AWSOME!!!!! check out their profiles & contact them. They are both a WEALTH of information & support.
