Surgical details such as leaving the jejunal mesentery intact and closing all created defects significantly decreased the incidence of SBO due to internal hernias in antecolic antegastric LRYGB.

Obese patients have similar SNP frequencies. Several SNP results are statistically associated to high blood pressure and T2D. POMC was significantly associated to a higher surgically induced weight loss.

LRYGBP as a revision procedure is feasible in most patients. Surgical complications are more frequent.

In obese patients undergoing bariatric surgery, abnormal preoperative spirometry predicts postoperative respiratory complications only in patients with OSAS.
