Robot-assisted vs. traditional sleeve gastrectomy
This study compares two types of weight-loss surgery: one done with the help of a robot and the other done by hand (laparoscopic). Both are types of sleeve gastrectomy, where the stomach is reduced in size. If you qualify for sleeve gastrectomy, this trial may help doctors learn which method works better.
Cleveland, OhioAges 18–70 - NCT06515691Recruiting
Nerve block for pain after weight loss surgery
This study tests a nerve block (an injection near the nerves) to see if it helps reduce pain after laparoscopic sleeve gastrectomy. The block is called a modified thoracoabdominal nerve plane block, and it may lead to better pain control and recovery.
Istanbul, BagcilarAges 18–65 - NCT07274215Recruiting
Nerve block injection for pain and nausea after sleeve gastrectomy
This study tests a special numbing injection (called a paragastric block) to see if it reduces pain and nausea after sleeve gastrectomy surgery. If you are having this weight-loss surgery, the injection might help you feel better and recover more comfortably.
IstanbulAges 18–65 - NCT02937649Recruiting
Testing a bougie tool during sleeve stomach surgery
This trial checks a specific surgical measuring tool (“bougie”) used during sleeve gastrectomy (weight-loss stomach surgery). It may help the surgical team improve how the sleeve is formed while keeping safety in mind.
Boulogne-BillancourtAges 18–70 - NCT07461610Recruiting
Stool analysis after sleeve gastrectomy vs gastric bypass
This trial compares changes in stool after two common weight-loss surgeries: sleeve gastrectomy and gastric bypass. It aims to understand how these surgeries affect digestion and gut health.

Weight-loss surgery and mood: comparing two surgical approaches
This study follows patients undergoing one of two common weight-loss surgeries (sleeve gastrectomy or gastric bypass) to see how each affects binge eating, depression, and anxiety. Researchers want to understand which surgery may help improve both weight and mental health outcomes.

Single-stage conversion of gastric bypass to sleeve gastrectomy
This trial is testing a single surgery that converts a previous gastric bypass into a sleeve gastrectomy, and checking if there is a higher risk of leaks. It may be an option for people who need this change and are in good overall health.
Cairo, Old CairoAges 18–70 - NCT07495020Recruiting
Weight loss surgery study for type 2 diabetes

Pregabalin during weight-loss surgery to reduce pain
This trial tests whether pregabalin can help with pain control for people having laparoscopic sleeve gastrectomy (a weight-loss surgery). It may help reduce the discomfort around surgery and improve the overall recovery experience.

Stomach stent for weight regain after sleeve gastrectomy
This trial is testing a special stomach stent (called a gastric bypass stent) to help people who regained weight after a sleeve gastrectomy. If you've had a sleeve gastrectomy and your BMI is 27.5 or higher, this study might help you lose weight again without another surgery.

Studying immune cells in stomach tissue after weight loss surgery
This study looks at how certain immune cells (mast cells and macrophages) and small blood vessels change in the stomach tissue of people who have weight loss surgery. It may help researchers better understand how the body responds to surgery and weight loss.

- How do I know if I qualify for a laparoscopic sleeve gastrectomy trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a laparoscopic sleeve gastrectomy trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
