Randomized Controlled Trial Multicenter Study
Five-year outcomes after laparoscopic gastric bypass and laparoscopic duodenal switch in patients with body mass index of 50 to 60: a randomized clinical trial.
There is no consensus as to which bariatric procedure is preferred to reduce weight and improve health in patients with a body mass index higher than 50. ⋯ In patients with a body mass index of 50 to 60, duodenal switch resulted in greater weight loss and greater improvements in low-density lipoprotein cholesterol, triglyceride, and glucose levels 5 years after surgery compared with gastric bypass while improvements in health-related quality of life were similar. However, duodenal switch was associated with more surgical, nutritional, and gastrointestinal adverse effects.

Randomized Controlled Trial Comparative Study
Comparison of Ivor-Lewis vs Sweet esophagectomy for esophageal squamous cell carcinoma: a randomized clinical trial.
Sweet esophagectomy is performed widely in China, while the Ivor-Lewis procedure, with potential benefit of an extended lymphadenectomy, is limitedly conducted owing to concern for a higher risk for morbidity. Thus, the role of the Ivor-Lewis procedure for thoracic esophageal cancer needs further investigation. ⋯ Early results of this study demonstrate that the Ivor-Lewis procedure can be performed with lower rates of postoperative complications and more lymph node retrieval. Ivor-Lewis and Sweet esophagectomies are both safe procedures with low operative mortalities.
