• Bowel Sounds and Day-to-Day Recovery After Colorectal Cancer Surgery

  This study will test whether monitoring bowel sounds before and after colorectal cancer surgery can predict how quickly patients recover bowel function and resume eating.

  Recruiting Zhongnan Hospital · Wuhan, Hubei · NCT07705139

• Liposomal Bupivacaine TAP Block Plus Pain Control to Help Gut Recovery After Major Abdominal Surgery

  This trial tests whether adding liposomal bupivacaine TAP block to a sufentanil or oxycodone-based pain plan helps people recover gut function after major abdominal surgery.

  Recruiting Tianjin First Central Hospital · Tianjin, Tianjin Municipality · NCT07651722

• Restrictive versus liberal IV fluids during elective cesarean with spinal anesthesia

  This trial will test whether giving less versus more IV fluids during spinal anesthesia reduces nausea and speeds bowel recovery for women having an elective cesarean.

  Recruiting Nigde Omer Halisdemir University · Niğde, Merkez · NCT07440667

• Chewing gum to speed bowel recovery after open gastrointestinal surgery

  This trial will test whether chewing glucose-containing gum after open gastrointestinal surgery helps adults' intestines start working sooner.

  Recruiting Khyber Medical University Peshawar · Peshawar, KPK · NCT07425249

• Tegileridine for faster bowel recovery after abdominal surgery

  This trial tests if tegileridine, given after abdominal surgery, helps the gut start working sooner compared with morphine while both are used with a patient-controlled pump.

  Recruiting at 3 sites Phase 4 Xiangya Hospital of Central South University · Guangzhou, Guangdong and 2 other locations · NCT07412223

• Thread-embedding acupuncture to speed bowel recovery after colorectal cancer surgery.

  This trial will test whether adding thread embedding acupuncture (with electroacupuncture) helps adults recover bowel function faster after elective laparoscopic colorectal cancer surgery.

  Recruiting Northern Jiangsu People's Hospital · Yangzhou, Jiangsu · NCT07071987

• Simple bed exercises to reduce postoperative ileus after colorectal surgery

  This test tries simple bed exercises to see if they help adults who develop postoperative ileus after elective colorectal surgery get their bowels working sooner.

  Recruiting The University of Hong Kong · Hong Kong · NCT07014046

• Efferent loop stimulation before ileostomy closure

  This study is testing if stimulating a part of the intestine with a special solution before closing an ileostomy can help patients recover better and have fewer complications after surgery.

  Recruiting Hospital Universitario La Paz · Madrid · NCT06974500

• Gastrointestinal stimulation to treat bowel paralysis after major surgery

  This study tests if using a pacemaker to stimulate the gut can help patients recover their bowel function faster after major abdominal surgery for certain cancers.

  Recruiting University of Aarhus · Aarhus · NCT05752071

• Using Dexamethasone to Prevent Post-surgery Bowel Issues After Cesarean Sections

  This study is testing if giving Dexamethasone can help women aged 18-40 recover better from bowel issues after having a cesarean section.

  Recruiting Phase 1/2 Assiut University · Asyut · NCT05654649

• Lowering abdominal gas pressure during laparoscopic large-bowel surgery to reduce postoperative ileus

  This trial will test whether using lower abdominal inflation pressure during laparoscopic large-bowel surgery helps adults recover bowel function faster and go home sooner.

  Recruiting Ohio State University · Columbus, Ohio and 1 other locations · NCT05344417

• Using pyridostigmine to treat postoperative ileus after colorectal surgery

  This study is testing if a medication called pyridostigmine can help people who have bloating and no bowel movements after colorectal surgery feel better.

  Recruiting Phase 2/3 The Cleveland Clinic · Cleveland, Ohio · NCT05334485

• Using beetroot juice to improve recovery after colorectal surgery

  This study tests if drinking beetroot juice before colorectal surgery can help adults recover faster and reduce complications after the operation.

  Recruiting at 5 sites Phase 2 University Hospital, Ghent · Edegem and 5 other locations · NCT05133024

NIH-funded research (3)

Early-stage science funded by the US National Institutes of Health. Most of these projects don't enroll patients, but they show what is being worked on.

• How gut support cells react to surgery and cause slow bowel recovery

  This project looks at whether calming a gut-supporting cell's response to mechanical stress can prevent the slow bowel recovery (postoperative ileus) some patients have after intestinal surgery.

  NIH research Ohio State University · Columbus, UNITED STATES · NIH-11252569

• Understanding how mechanical stress affects bowel function after surgery

  This study is looking at how surgery can affect your bowel movements afterward, specifically how a special sensor in your body responds to pressure during the operation, with the goal of finding better ways to help you recover and feel better after gastrointestinal surgery.

  NIH research Ohio State University · Columbus, UNITED STATES · NIH-11029259

• Investigating how glial cells affect gut movement after surgery

  This study is looking at how certain cells in the gut might affect digestion problems that can happen after surgery, and it aims to find ways to help patients recover better after gastrointestinal surgeries.
