Could a poop pill help heal after colon surgery?

First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 3 times
Summary
This early study is testing whether giving a transplant of healthy gut bacteria (called IMT) through a feeding tube is safe and doable in 40 adults who have had part of their colon removed due to diverticulitis or sigmoid colon cancer. Participants get the transplant a couple of days after surgery and are followed for up to 6 months to check for side effects and changes in their gut microbiome. The goal is to see if this approach is safe enough to study further for preventing infections like recurrent C. diff.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- intestinal microbiota transplant (IMT) solution
- What this could lead to
- If it works, this could point toward a way to restore healthy gut bacteria after colon surgery and reduce complications like recurrent C. diff infection.
- What could go wrong
- This is a very early Phase 1 pilot study with only 40 people, so it is designed just to test safety and feasibility, not effectiveness. There is a small risk of bowel perforation from the feeding tube, and the transplant may not engraft or provide benefit.

Inclusion Criteria: * Able/willing to provide informed consent * Between 18-75 years of age * Undergoing surgery for a history of diverticulitis or sigmoid colon cancer. * Able to provide fecal samples * Stated willingness to comply with all study procedures and availability for the duration of trial to follow-up by telephone, in-person, email, and/or video visits or correspondence Exclusion Criteria: * Any history of inflammatory bowel disease * Pregnancy or breastfeeding. A pregnancy test will be obtained from females of child- bearing potential on the proposed day of IMT (prior to the receipt of IMT). Patients with a positive pregnancy test will be excluded. A negative result will be required for subjects who are females of child-bearing potential to receive IMT treatment. * Life expectancy of \< 6 months * Presence of ileostomy or colostomy * Known history of inflammatory bowel disease (Crohn's, Ulcerative Colitis) * Patients on immunosuppressants (calcineurin inhibitors, prednisone ≥ 20 mg/day, methotrexate, azathioprine, immunosuppressive biologics, JAK inhibitors) * Patients with neutropenia (an absolute neutrophil count \< 0.5 x 109 cells/L) obtained on a complete blood count with differential at screening. * History of solid organ or bone marrow transplant. * Anticipated recurrent antibiotic use (e.g., patients with frequent urinary tract infections or sinusitis). * History of severe anaphylactic food allergy. * History of celiac disease. * Patients receiving cancer chemotherapy, immunotherapy, or radiation.
