DS vs RNY common Channel length

Trying to prepare my argument for a revision to the DS.  Can someone tell me what is the average bypassed amount for each surgery?

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!

 I have had the ERNY as a revision and my CC is 75 cm.  The shorter the length of the CC (portion of the intestine where the food and enzymes meet) the higher the potential risk for nutritional and vitamin deficiencies.  

Good Luck.

Ok... I found this chart online. 

	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????

There is definately LOTS of information to be had on these boards!!!

Thank you so much for all the advice/experience.  I truly appreciate the input and information regarding the DS... and I truly believe it is the best surgery for me.  BUT...

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.

Honestly RNY is not that bad !

You know who would be a GREAT person to talk to about the RNY surgery?
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.
(RNY) Michelle (Vitalady) http://www.obesityhelp.com/member/vitalady/   Melting Mama (Beth) http://www.obesityhelp.com/member/meltingmamaish/


I hope this additional info helps you out.
