Chongqing, Chongqing MunicipalityAges 18–75 - NCT03385018Recruiting
Laparoscopic total stomach surgery trial for stomach cancer
This trial studies whether a minimally invasive (laparoscopic) removal of the entire stomach, along with lymph node removal, can be done safely and effectively for certain stomach cancers. It may be an option if your cancer is in the stomach, has limited spread to nearby lymph nodes, and can be fully removed.
SeoulAges 20–80 - NCT06783751Recruiting
New surgical method to reduce acid reflux after weight loss surgery
This trial tests a modified version of sleeve gastrectomy that aims to reduce the risk of acid reflux (GERD) after surgery. It is for people aged 18–65 with a BMI between 35 and 55 who already have some degree of GERD and are planning to have weight loss surgery.
Orange, CaliforniaAges 18–65 - NCT04710758Recruiting
Keyhole surgery for advanced stomach cancer
This trial looks at laparoscopic (keyhole) total stomach removal for people with advanced stomach cancer in the upper or middle part of the stomach. It aims to see whether this operation approach is safe and useful based on your tumor stage and overall health.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04994665Recruiting
Test of fixing the stomach to reduce reflux after sleeve surgery
This study checks whether a surgical “fix” (omentumpexy) can reduce acid reflux after sleeve gastrectomy. It’s mainly for adults having sleeve surgery who have a higher-risk body weight and related health problems.
BayonneAges 18 years+ - NCT05211375RecruitingPhase 3
Compare two weight-loss surgeries for type 2 diabetes control
This Phase 3 trial compares sleeve gastrectomy versus a different bypass-style operation to improve blood sugar in adults with type 2 diabetes. It may help some people lower blood sugar and diabetes medication needs, but you must meet specific safety and health criteria.
Seongnam-siAges 18 years+ - NCT05330910Recruiting
Repair of a stomach valve during sleeve weight-loss surgery
This trial tests whether doing a specific repair near the stomach valve (the gastroesophageal junction) during laparoscopic sleeve gastrectomy can help people with a loose valve. It is aimed at adults who have a particular endoscopy finding (Hill grade III) and choose this weight-loss surgery.
SingaporeAges 21–65 - NCT05344339Recruiting
Compare two stomach reconstruction methods after stomach cancer surgery
This study compares two surgical reconstruction techniques after a distal gastrectomy (removing the lower part of the stomach) for gastric (stomach) cancer. It may help find which method leads to better recovery and outcomes after surgery.
Ho Chi Minh CityAges 18–80 - NCT05704348Recruiting
Test to reduce reflux after sleeve stomach surgery
This study looks at whether a treatment plan called “Sleeve-pex” can reduce heartburn and reflux after sleeve gastrectomy. If you’re planning this surgery and can complete symptom questionnaires, you may be able to join and help compare outcomes between groups.
FørdeAges 18 years+ - NCT06768463Recruiting
Stomach cancer surgery after chemo for limited spread
This trial tests if surgery to remove the stomach and some tumors, after a few months of chemo, helps people whose stomach cancer has spread to only a few nearby spots (like the lining of the belly, liver, or lymph nodes) live longer compared to chemo alone.
Ho Chi Minh City, Ho Chi MinhAges 18–75 - NCT07142122Recruiting
Comparing two types of stomach surgery for early upper gastric cancer
This trial compares two laparoscopic surgeries for early-stage stomach cancer in the upper part of the stomach. It looks at whether preserving a nerve (celiac branch of vagus nerve) during surgery leads to better recovery while still removing the cancer safely.
Fuzhou, FujianAges 18–75 - NCT07482566Recruiting
Comparing two surgeries for advanced gastroesophageal junction cancer
This trial compares two types of stomach-removing surgeries (total vs. partial gastrectomy) in people with a certain kind of advanced gastroesophageal junction cancer. The goal is to find out which surgery leads to better outcomes.
Istanbul, IstanbulAges 18–90 - NCT06242613Enrolling by invitation
Robot vs. laparoscopic surgery for stomach cancer
This study compares robot-assisted surgery to standard laparoscopic surgery for people with stage Ib, II, or III stomach cancer. It aims to see which approach leads to better recovery and outcomes.
Las Palmas de Gran Canaria, Las PalmasAges 18 years+ - NCT06058442RecruitingPhase 3
Digestive enzymes after stomach surgery trial
