Hypothyroidism appears to improve in the vast majority of morbidly obese patients who undergo LRYGB, except for those whose thyroid disease is autoimmune in nature.

The use of warmed, humidified CO2 insufflation in bariatric patients undergoing LRYGBP was not associated with any significant benefit with regards to postoperative pain.

LRYGB is safe and effective in morbidly obese patients > or =55 years of age.

In this study of patients undergoing DS, being SSO -- specifically SSO men -- was associated with increased mortality. Further studies will be needed to better determine the precise mechanism of these risk factors leading to such an elevation in mortality. Until then, caution should be exercised before performing DS in male patients with BMI > or =60 kg/m2.
