Randomized Controlled Trial Comparative Study
Perineal transanal approach: a new standard for laparoscopic sphincter-saving resection in low rectal cancer, a randomized trial.
Laparoscopic sphincter preservation for low rectal cancer is challenging because of the high risk of positive circumferential resection margin. We hypothesized that perineal dissection of the distal rectum may improve quality of surgery, compared with the conventional abdominal dissection. ⋯ Perineal rectal dissection reduces the risk of positive circumferential resection margin, as compared with the conventional abdominal dissection in low rectal cancer. This suggests the perineal rectal dissection as a new standard in laparoscopic sphincter-saving resection for low rectal cancer.

Randomized Controlled Trial Multicenter Study
The effect of the endoscopic duodenal-jejunal bypass liner on obesity and type 2 diabetes mellitus, a multicenter randomized controlled trial.
Investigate the safety and efficacy of 6 months' duodenal-jejunal bypass liner (DJBL) treatment in comparison with dietary intervention for obesity and type 2 diabetes mellitus (T2DM). ⋯ The DJBL is a safe and effective alternative to invasive bariatric procedures. Six months of DJBL treatment combined with diet leads to superior weight loss and improvement of T2DM when compared with diet alone.
