Question:
Okay, I'm thoroughly confused! Limbs long or short?

Can someone please provide a concise definition of the differences between the long and short limb RNY? Is one distal where the other is proximal or does the length of the limb have nothing to do with the length of the bypassed section? Thanks everyone!    — Sharon F. (posted on June 29, 2000)

Generally, long limb is a distal bypass and whort limb is a proximal bypass. The actual length of the bypass varies from surgeon to surgeon and patient to patient. I had a DS with a 100cm common tract, which makes mine a distal operation. People who've had distal and proximal RNYs may be able to give you more information about the actual length of their bypasses. Good luck with your research!

Interestingly, most DS patients, who definitely have a distal bypass, need about the same amount of protein as Proximal RNy patients, about 60g per day. I'm an exception, requiring about 90g per day, even though my common tract is 100cm (just over 3 feet), about the same as most other DSers. It's not particularly important, just one of those Gee Whiz things, I guess.

i had an open rny proximal. my surgeon bypasses 225 cm and still calls that proximal. he says a distal bypass only leaves about 75cm of common tract. he feels the results with his limb are as good without any nutritional consequences. i'm only 2/12 weeks out so we'll see. good luck shelly
