Recruiting studies
- NCT06810232Enrolling by invitation
Health factors and longer hospital stay after endoscopy
This study looks at how general health factors (like age and other medical conditions) might affect how long you need to stay in the hospital after a routine stomach or bowel exam called an endoscopy. The goal is to understand which patients may need extra care so hospitals can plan better.
IstanbulAges 18 years+ - NCT07550582Enrolling by invitationPhase 2
Surgery for small tumors at the food pipe opening
This trial tests a new surgical approach combining laparoscopic (minimally invasive) surgery with endoscopy (a camera procedure) to remove small tumors located where the esophagus meets the stomach. The goal is to safely remove these tumors while preserving normal function.
Beijing, Beijing MunicipalityAges 18–80 - NCT07708012Enrolling by invitation
Laparoscopic and endoscopic surgery for early stomach cancer
This trial studies a combined surgical approach using a camera through small incisions (laparoscopy) and a flexible tube through the mouth (endoscopy) to treat early-stage stomach cancer. It aims to see if this approach can safely remove the cancer while sparing nearby lymph nodes.
Qingdao, ShandongAges 18–80 - NCT07081802Recruiting
Acupuncture and herbs for bowel recovery after surgery
This study tests whether a special type of acupuncture (transcutaneous electrical acupoint stimulation) along with traditional Chinese medicine can help your bowels recover faster after abdominal surgery. It is for people having surgery on the liver, gallbladder, pancreas, stomach, or intestines.
Beijing, Beijing MunicipalityAges 18–80 - NCT07651722Recruiting
Pain control and gut recovery after abdominal surgery
This trial tests a combination of two pain-management approaches—a long-acting numbing medicine injected near nerves and a self-administered opioid—to see if they help your gut function better and control pain after bowel or colon surgery.
Tianjin, Tianjin MunicipalityAges 18–80 - NCT07307495Recruiting
Pain relief after back surgery and its effect on recovery
This study tests a new painkiller, oliceridine fumarate, given through a pump after lumbar spine surgery. The goal is to see if it helps the bowels and stomach recover faster compared to standard pain relief.
Xi'an, ShaanxiAges 18–75 - NCT07412379Recruiting
Predicting recovery after cancer surgery for older adults
This study looks at how older adults (65+) with digestive tract cancers respond to surgery aimed at a cure. Researchers want to see what factors affect recovery and quality of life after the operation.
BogotáAges 65 years+ - NCT06538948Recruiting
Eating behavior after weight loss surgery
This study measures how people eat and how their gut hormones change after weight loss surgery. It compares different groups to understand differences between men and women.
Männedorf, Canton of ZurichAges 18 years+ - NCT05752071Recruiting
Stomach stimulation to help bowel recovery after major surgery
This trial tests a stomach (gastrointestinal) stimulation approach to help your bowels start working again after extensive surgery, which may cause a temporary problem called postoperative ileus. If it helps, it could mean faster recovery and less time with bowel-related complications.
AarhusAges 18 years+ - NCT03716089Recruiting
Laparoscopic surgery for stomach GIST by tumor site
This trial studies whether doing laparoscopic surgery for stomach GISTs (gastrointestinal stromal tumors) works and is safe when the tumor is in a “favorable” versus “unfavorable” location. You might be eligible if your tumor is confirmed as GIST and doctors expect to remove it completely using keyhole surgery.
Fuzhou, FujianAges 18–75 - NCT06731998Recruiting
Improving pain control after cancer surgery
This study compares different methods of managing pain after minimally invasive surgery for abdominal cancers. It aims to find which approach works best to reduce pain and improve recovery.
Pittsburgh, PennsylvaniaAges 18–89 - NCT01416714Recruiting
Tissue sample collection during cancer surgery or biopsy
This study is collecting tissue samples from people with certain cancers while they have surgery or a biopsy. It may help researchers learn more about these cancers and improve future diagnosis and treatment.

Common questions
- Are there clinical trials for gastrointestinal surgery?
- Yes. Clin2 currently lists 36 recruiting gastrointestinal surgery studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a gastrointestinal surgery 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 gastrointestinal surgery 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.
