Question:
Follow-up question regarding medial RNYs?

Someone asked a questions about "medial RNYs." My biggest concern about proximal RNYs has always been the potential for "long-term efficacy." When I asked my surgeon if there was anything he could do to increase the "malabsorption factor" of my proximal RNY (he refuses to perform distal RNYs), he agreed to make my roux limb long (i.e., 150cm). His normal length for roux limbs is 100cm. Can anyone tell me how much is bypassed in a typical "medial RNY?" I'm wondering now whether my RNY is actually closer to a "medial RNY" rather than a "proximal RNY." Any input would be greatly appreciated!!! Thanks.    — Julie K. (posted on August 22, 2002)

The noraml roux length for a Proximal is 100cm (and then 400cm for the common channel). The distal is a 400cm roux(and then a 100 cm common channel). Medial is an adjustment between the 2. I don't beleive there are any set lengths. I will tell you that with the distal there is a greater risk of malnutrition. I hope this helps. I used my docs. illustrations.

I've been told that a distal is 150 cm or more bypassed and that under that it is considered a proximal. Haven't heard of the medial, but I guess it would be between 100 and 150? I had 110 cm bypassed and my doctor called it a proximal.

My Dr. explained that a proximal is approx. 70cm, a long limbed 150cm and a distal 700cm. I too had a long limbed RNY because my BMI was over 50 at the time of the surgery. I've had no problems so far. Good luck to you!
