Et tarmbehandlingsprogram (retrograd rektalt klyster) for behandling av lavt fremre reseksjonssyndrom hos endetarmskreftpasienter

2. oktober 2026 oppdatert av: Alessandra, Ohio State University Comprehensive Cancer Center

Lavt fremre reseksjonssyndrom: Retrograd klysterprogram vs medisinsk behandling

This clinical trial studies if a bowel management program with a retrograde rectal enema (RRE) for the treatment of low anterior resection syndrome (LARS) in rectal cancer patients is better than medical management alone. Rectal cancer treatment can include a procedure where part of the rectum with cancer is removed and the remaining part of the rectum is reconnected to the colon, this is called a low anterior resection of the rectum. LARS is a common condition that can develop after undergoing a low anterior resection of the rectum. LARS consists of any change in how the body performs defecation, the discharge of feces from the body, after undergoing a resection procedure. Patients with LARS may experience fecal urgency, incontinence, increased frequency, constipation, feelings of incomplete bowel movement, or bowel emptying difficulties. Patients may experience individual symptoms of LARS or a combination of them. A bowel management program assists patient's with identifying a specific bowel management regimen that works best for managing symptoms of LARS. A RRE consists of inserting a catheter through the anus into the rectum. The RRE is designed to assist fecal emptying. Medical management of LARS can include the use of fiber, loperamide hydrochloride, or pelvic floor physical therapy. Fiber may help relieve constipation, feelings of incomplete bowel movement, or bowel emptying difficulties. Loperamide hydrocholoride may help lessen fecal urgency, incontinence, or increased frequency. Pelvic floor physical therapy may help restore strength in the rectum possibly helping to improve symptoms of LARS. Participating in a bowel management program with a RRE may be more effective in treating LARS than medical management alone.

Detaljert beskrivelse

PRIMARY OBJECTIVE:

I. To compare two approved pathways for treatment of low anterior resection syndrome (LARS) - a retrograde enema program versus a medical management pathway.

SECONDARY OBJECTIVE:

I. The determination of feasibility to complete this treatment pathway.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP I: Patients undergo a bowel management program comprising a medical management pathway (fiber, loperamide hydrochloride, pelvic floor physical therapy) in combination with RRE treatment for 1 year. Patients use the RRE system to self administer an individualized enema regimen via the rectum. Patients may undergo abdominal film x-rays throughout the trial.

GROUP II: Patients receive medical management comprising fiber, loperamide hydrochloride, and pelvic floor therapy for 1 year. If medical management fails, patients may then be referred for surgery with sacral nerve stimulator placement.

Upon completion of study intervention all patients are followed up at 1 month, 3 months, and 1 year.

Beskrivelse

Inclusion Criteria:

  • Age ≥ 18 years old
  • Moderate to Severe LARS diagnosis
  • Patients with history of rectal cancer that was treated with proctectomy
  • Has undergone standard medical management without improvement of symptoms for 3-6 months

Exclusion Criteria:

  • Patients presenting with significant stricture that need a definitive surgical management strategy; patients with minor or clinically negligible strictures can still be candidates. Patients who are able to pass the catheter and the balloon per rectum may be candidates after a digital rectal exam at their initial visit
  • Patients with any chemo or radiation therapy in the last 6 months
  • Patients who currently have colorectal cancer
  • Patients with recurrent colorectal cancer
  • Patients who have undergone a colorectal surgical procedure within the last three months
  • Patients with progressive neurological disease
  • Patients with active or recurrent sacral infection
  • Patients < 18 years old
  • Active sacral nerve simulator
  • Pregnant or planning to become pregnant during the treatment portion of the study
  • Altered mental status or mental disability that would alter ability to self-administer enema
  • Any reason the research team believes the subject is not an appropriate candidate for this study (i.e., transportation issues, history of no-show appointments, lack of reliable communications, vulnerable population(s), etc.)
