Recruiting studies
- NCT06798376Recruiting

This study keeps track of how people recover after surgery to remove the upper part of the stomach and nearby lymph nodes. It mainly helps doctors understand which surgical reconstruction methods work best and how patients do over time.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05325736Recruiting
Study how bariatric surgery changes blood sugar response
This study looks at how blood sugar responds after bariatric surgery (or related surgery) and whether changes can be measured over time. It may help doctors better understand which people respond best after surgery.
RehovotAges 18–70 - NCT07327905Recruiting
Lidocaine or dexmedetomidine for pain during weight-loss surgery
This trial compares two medicines given through an IV during sleeve gastrectomy (weight-loss surgery) to see which provides better pain control. It may help patients have a smoother recovery with less discomfort.
AlexandriaAges 20–50 - NCT07313293Recruiting
Foot reflexology for nausea after weight-loss surgery
This trial tests if foot reflexology can help reduce nausea after sleeve gastrectomy (a type of weight-loss surgery). You may join if you are scheduled for this surgery and do not have foot problems or take strong pain medications.
La Roche-sur-YonAges 18 years+ - NCT04443478Recruiting
Keyhole versus open lymph node surgery for junction cancer
This trial compares two ways of removing lymph nodes during surgery: keyhole (laparoscopic) versus open surgery. It is for people with esophagus-stomach junction adenocarcinoma, aiming to see which approach works better and is safer.
Beijing, Beijing MunicipalityAges 18–80 - NCT04483076RecruitingPhase 3
Chemo before stomach surgery with different cycles
This trial studies whether giving oxaliplatin plus S-1 (SOX) chemotherapy before stomach surgery works best when given for different cycle lengths. It may help shrink stage III gastric cancer before a standard D2 gastrectomy and improve outcomes.
Beijing, Beijing MunicipalityAges 18–70 - NCT04740346Recruiting
Study survival and quality of life by follow-up time after stomach surgery
This study looks at how long people with stage II or III stomach (gastric) cancer tend to live and how their day-to-day well-being changes over different follow-up times after surgery. It may help doctors understand the best follow-up schedule to support recovery.
Goyang-si, Gyeonggi-doAges 19 years+ - NCT04901429Recruiting
Check truncal nerve procedure during weight-loss surgery
This study looks at a nerve-related surgical step (“truncal vagotomy”) during revision weight-loss surgery that changes a sleeve stomach to a gastric bypass. It may help improve outcomes for people who need this type of second surgery.
Dallas, TexasAges 18 years+ - NCT05242835Recruiting
Study for weight regain after sleeve stomach surgery
This trial studies a specific type of metabolic (weight-related) surgery for people whose sleeve gastrectomy did not lead to enough weight loss or has caused significant weight regain. It may help improve long-term weight and related health problems.
Québec, QuebecAges 18–60 - NCT05494086Recruiting
Laparoscopic stomach surgery for early gastric cancer
This study looks at a surgical technique (“dual-port laparoscopic distal gastrectomy”) for people with stomach adenocarcinoma at an early, specific stage. The goal is to remove the tumor with clean margins (called an “R0” result) and see how this approach works safely.
Guangzhou, GuangdongAges 18–75 - NCT05593458RecruitingPhase 3
Stomach cancer surgery before chemo: artery-based or drip chemo
This trial compares two ways of giving chemotherapy before surgery for locally advanced stomach or stomach–esophagus cancer: chemo sent through an artery versus chemo given through an IV line. It also studies adding PD-1 immunotherapy to see which approach works better and is safer.
Hangzhou, ZhejiangAges 18–75 - NCT05618821RecruitingPhase 2
Indocyanine green dye during stomach surgery for leftover cancer
This Phase 2 study tests whether using a special light-activated dye (indocyanine green) during laparoscopic stomach surgery can improve surgical outcomes for people with remnant (leftover) stomach cancer that has not spread to distant organs. It may help surgeons better find lymph nodes while operating.
Fuzhou, FujianAges 18–75 - NCT05777928Recruiting
Tests satiety changes after bariatric surgery revision
This study looks at how feelings of fullness (satiety) change in people getting bariatric surgery—either a sleeve gastrectomy or a revision procedure. It may help improve how well weight-loss stays on track after surgery.
MilanAges 18–65 - NCT05804591RecruitingPhase 4
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.
Warsaw, WarsawAges 18 years+ - NCT05871099RecruitingPhase 3
Laparoscopic stomach surgery with added heated fluid chemotherapy
This trial compares standard laparoscopic surgery for stomach cancer versus the same surgery plus HIPEC, which is heated chemotherapy placed in the abdomen during the operation. It aims to see if adding the heated chemotherapy improves outcomes for people with higher-stage stomach cancer.
Qingdao, ShandongAges 18–80 - NCT06027242Recruiting
Glutamine supplement after stomach cancer surgery
This trial tests if taking glutamine (a nutrient) as an oral supplement helps patients recover after surgery to remove stomach cancer. It aims to see if it improves healing and quality of life.
TaipeiAges 20 years+ - NCT06055387Recruiting
Frailty care for older stomach cancer patients after surgery
This study tests a frailty assessment and intervention program for people aged 65+ with stage II or III stomach cancer who will have surgery and chemotherapy afterward. It aims to improve recovery and quality of life.
Taoyuan, TaiwanAges 65 years+ - NCT06121700RecruitingPhase 2
Chemoimmunotherapy and radiation before surgery for limited spread stomach cancer
This trial tests combining chemotherapy, immunotherapy, and radiation before surgery for stomach or gastroesophageal junction cancer that has spread to a limited number of sites. The goal is to see if this approach can improve outcomes by shrinking tumors before they are removed.
ShanghaiAges 18–75 - NCT06186089Recruiting
How stomach surgery affects gut bacteria and your thinking
This study looks at how having stomach cancer surgery changes your gut bacteria and thinking abilities. Researchers want to understand if these changes affect memory or brain function after the operation.
Wuhan, HubeiAges 40–80 - NCT06257771Recruiting
Alcohol and gastric sleeve surgery study
This study looks at how alcohol affects people who have had gastric sleeve surgery (a type of weight loss surgery) compared to those who haven't. It may help explain if surgery changes how your body processes alcohol.
Urbana, IllinoisAges 21–64 - NCT06271317Recruiting
Complications after sleeve gastrectomy study
This study looks at complications after a type of weight-loss surgery called sleeve gastrectomy (removing part of the stomach). If you are considering this surgery and meet the weight/health guidelines, you may be able to join to help doctors learn more about risks and recovery.
Nantes, NantesAges 18 years+ - NCT06300879Recruiting
New surgery technique for upper stomach or junction cancer
This study tests a new surgical technique for removing cancer in the upper stomach or where the stomach meets the esophagus. It aims to see if this technique is safe and effective for people with early-stage adenocarcinoma who haven't had other cancer treatments.
