Gut instinct: listening to bowel sounds may reveal hidden clues about surgical recovery
NCT ID NCT07705139
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study looks at whether monitoring bowel sounds before and after colorectal cancer surgery can help doctors assess how well the intestines are recovering. Researchers will track 172 patients and compare bowel sound patterns with outcomes like time to first gas, ability to eat, and complications such as bowel blockage. The goal is to see if this simple, non-invasive method could become a useful tool for guiding postoperative care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple, non-invasive way to monitor recovery after colorectal surgery and potentially reduce complications.
- What could go wrong
- This is an observational study, so it cannot prove cause and effect. The results may not change current practice without further validation.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Aged 18-80 years. * Histopathologically confirmed colorectal adenocarcinoma according to the WHO 2022 classification. * No restriction on prior neoadjuvant or other antitumor therapies, including chemotherapy, radiotherapy, targeted therapy, or immunotherapy. * Able to understand the study requirements and voluntarily provide written informed consent (patient and/or legally authorized representative). * Able to communicate effectively with the investigators and willing to comply with all study procedures, including postoperative management and follow-up. Exclusion Criteria: * Significant organ dysfunction indicating inability to tolerate surgery or an unacceptably high perioperative risk, including: * Severe cardiac dysfunction (NYHA Class III or IV). * Severe hepatic dysfunction (MELD score \>12). * Severe renal dysfunction (eGFR \<30 mL/min/1.73 m² \[CKD stage 4-5\] or end-stage renal disease requiring dialysis). * Severe pulmonary dysfunction (resting PaO₂ \<60 mmHg on room air or respiratory failure requiring long-term oxygen therapy or mechanical ventilation). * Participation in another clinical study within 4 weeks before enrollment or concurrent participation in another interventional clinical study. * Emergency surgery required because of intestinal obstruction, perforation, or other acute abdominal conditions. * Severe psychiatric disorders that would interfere with compliance with perioperative management or follow-up. * Pregnant or breastfeeding women. * Any other clinical or laboratory abnormality that, in the opinion of the investigator, would make the participant unsuitable for the study.
