Biliary Limb as a Percentage From the Small Intestine Rather Than Fixed Length in Loop Bypass Surgery for Morbid Obesity

Study Overview
=================
Brief Summary
-----------------
in all loop bypass bariatric procedure (mini gastric bypass & single anastomosis sleeve jejunal bypass), biliary limb is fixed length. we do it as a percentage from total small intestine length rather than fixed length

Detailed Description
-----------------
in all loop bypass bariatric procedure (mini gastric bypass & single anastomosis sleeve jejunal bypass), biliary limb is fixed length we count the length of small intestine and do it as a percentage from total small intestine length rather than fixed length
