Trial Summary

What is the purpose of this trial?

The Comparison of Outcomes of Management of Bowel Obstruction (COMBO Pilot) Pilot trial is a patient-level randomized trial of a short course of dexamethasone + supportive care vs supportive care alone for patients with adhesion-related small bowel obstruction (aSBO). The goal of the COMBO trial is to answer the question: Can Dexamethasone increases the proportion of patients with resolution of aSBO with non-operative management (without complication) based on an established minimal important clinical difference.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators for more details.

What data supports the effectiveness of the drug Dexamethasone for treating small bowel obstruction?

Dexamethasone has been shown to help with breathing issues in infants by reducing inflammation and improving lung function, which suggests it might also help reduce inflammation in other conditions like small bowel obstruction.12345

Is dexamethasone generally safe for use in humans?

Dexamethasone has been used safely in various surgeries, including colorectal and tympanomastoid surgeries, to reduce nausea and vomiting. It has also been used in treating conditions like esophageal strictures in infants and inflammatory bowel disease in animal models, showing positive safety profiles in these contexts.678910

How does the drug dexamethasone differ from other treatments for small bowel obstruction?

Dexamethasone is unique because it may influence the body's growth factors, potentially affecting the healing process in the intestines, which is different from other treatments that might not target these specific pathways. It has been shown to alter enzyme activities and growth factor levels, which could impact how the intestines adapt after surgery.1791112

Eligibility Criteria

This trial is for adults over 18 with a small bowel obstruction likely caused by adhesions, as confirmed by CT scans and symptoms. They must be able to consent in English and not need immediate surgery. Excluded are those incarcerated, showing signs of peritonitis, allergic to dexamethasone, at high infection risk due to latent infections, or who've had recent surgery.

Treatment Details

Interventions

  • Dexamethasone
Trial Overview The COMBO Pilot study is testing if adding dexamethasone to supportive care improves non-surgical resolution of adhesive small bowel obstructions without complications compared to supportive care alone. Participants are randomly assigned to one of the two treatment approaches.

Group I: DexamethasoneActive Control2 Interventions
8 mg IV daily in the morning continued for up to 5 days until SBO is resolved or patient becomes surgical candidate.
Group II: Supportive CarePlacebo Group1 Intervention
Supportive care in both arms includes nasogastric tube (NGT) decompression, hydration, and serial exams to rule out bowel compromise.
