BornaAges 18 years+ - NCT05611697Recruiting
Compare two weight-loss surgeries for severe obesity
This trial compares two types of bariatric (weight-loss) surgery to see which helps people with severe obesity lose weight and stay healthy. You might be eligible if you’re between 20 and 60 and are already being referred for bariatric surgery after prior unsuccessful weight-loss attempts.
Tønsberg, VestfoldAges 20–60 - NCT05514769Recruiting
Surgery type comparison for early-to-mid stomach cancer
This trial compares two different stomach cancer surgeries after removing the tumor, to see which works better for patients with stomach adenocarcinoma. It may help determine the safest approach and best recovery outcomes for people whose cancer has not spread.
Nanchong, SichuanAges 18–85 - NCT04411823Recruiting
Predicting reflux after stomach sleeve surgery
This trial looks at how to predict who will develop acid reflux after a “stomach sleeve” operation. It may help doctors choose the safest plan before surgery and better prevent reflux afterward.
Orlando, FloridaAges 18 years+ - NCT07714980Recruiting
Acupoint stimulation timing for stomach cancer surgery recovery
This trial tests whether giving a gentle, needle-free acupoint stimulation before or after stomach cancer surgery helps speed up recovery. The stimulation uses a small device on the skin, similar to a tens unit, to support recovery after laparoscopic gastrectomy.
Dongying, ShandongAges 18–80 - NCT07789184RecruitingPhase 3
Surgery versus no surgery after successful conversion therapy for stomach cancer with peritoneal spread
This trial compares having surgery to remove stomach cancer versus not having surgery in patients whose cancer in the abdominal lining responded well to initial treatment. The goal is to see which approach helps patients live longer and feel better.
Beijing, Beijing MunicipalityAges 18–70 - NCT02811900Recruiting
Study of outcomes after weight-loss (bariatric) surgery
This study follows adults who have bariatric (weight-loss) surgery to see what outcomes they experience afterward. It may help doctors better understand how well the surgery works in real life.
StrasbourgAges 18 years+ - 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 - NCT05539105Recruiting
Watching recovery after surgery for upper stomach cancer
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 - 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 - 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 - 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 - NCT07823816Enrolling by invitation
Lung-protective ventilation for stomach removal surgery
This study tests a type of breathing support during surgery to remove the stomach (gastrectomy) that may protect the lungs. It aims to see if this approach reduces complications and helps patients recover better.
