Early discharge with home hospital care after bariatric surgery
This study tests whether discharging patients 24 hours after bariatric surgery and following up with Hospital-at-Home care is safe and cost-effective compared with the traditional 48-hour hospital stay.
-
Nissen‑Sleeve versus Roux‑en‑Y gastric bypass for reflux in people with severe obesity
This trial tests whether Nissen‑Sleeve gastrectomy or Roux‑en‑Y gastric bypass better controls GERD symptoms in adults who are eligible for bariatric surgery due to severe obesity.
-
Using TIPS before sleeve gastrectomy to improve outcomes for people with cirrhosis and severe obesity
This trial tests whether placing a TIPS (a portal decompression procedure) before sleeve gastrectomy helps adults with cirrhosis, clinically significant portal hypertension, and severe obesity lose weight, feel better, and have fewer complications.
-
Endoscopic conversion of sleeve gastrectomy to a new bypass method for reflux and obesity
This study is testing a new, less invasive procedure to help people who haven't lost enough weight or have gained weight back after sleeve gastrectomy by converting it to a different type of bypass surgery.
-
Impact of Sleeve Gastrectomy on Bone and Muscle Health in Men and Women
This study is trying to see how sleeve gastrectomy affects bone and muscle health in men and women over three years.
