Brief summary

To determine which method of performing the Duodenal Switch procedure leads to greater weight loss.

Interventions

Compare 2 different ways of performing the Duodenal Switch. A standard 100cm common channel and 150 cm alimentary limb vs a tailored small bowel partition. To determine which technique provides superior weight loss and resolution of co-morbidities. In order to tailor the small bowel the total small bowel length is measured intra-operatively. A common channel of 10% of the total small bowel length (but not less than 100cm) is fashioned. The alimentary limb is 40% of the total small bowel len

A common channel of 10% of the total small bowel length (but not less than 100cm) is fashioned. The alimentary limb is 40% of the total small bowel length. The small bowel anastamosis is performed in a side to side stapled fashion. This is a descrition of the tailored small bowel partition. Approximate length of surgery 3-4 hours.
