Dexamethasone for Small Bowel Obstruction

(COMBO Trial)

This trial explores whether adding dexamethasone, a type of steroid, to supportive care can resolve small bowel obstructions caused by adhesions (bands of scar tissue) without surgery. Participants will receive either dexamethasone with supportive care or just supportive care, which may include treatments like IV fluids and stomach decompression. It targets individuals with bowel obstructions due to scar tissue from past surgeries who do not currently require emergency surgery. As a Phase 4 trial, the treatment is already FDA-approved and proven effective, and this research aims to understand how it benefits more patients.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Research shows that dexamethasone is generally safe for people with adhesive small bowel obstruction (SBO). Studies have found that administering dexamethasone through an IV not only reduced the need for surgery but was also well-tolerated by patients. Specifically, a review of studies found that using dexamethasone led to about a 50% decrease in unresolved SBO cases, with few side effects. Serious side effects were rare, making it a promising option for managing SBO without surgery. Overall, the evidence suggests that dexamethasone is a safe treatment for small bowel obstruction when used correctly.¹²³⁴⁵

Most treatments for small bowel obstruction rely on supportive care methods like nasogastric tube decompression and IV hydration. However, Dexamethasone stands out because it is an anti-inflammatory steroid that is administered intravenously, potentially reducing inflammation and speeding up recovery. Researchers are excited about Dexamethasone because it offers a new approach by directly addressing inflammation, which could result in quicker symptom relief and earlier resolution of the obstruction compared to traditional methods.

This trial will compare dexamethasone with supportive care for treating small bowel obstruction. Studies have shown that dexamethasone can help treat adhesive small bowel obstruction (aSBO). In one study, 92% of patients who received dexamethasone improved without needing surgery, compared to 75% in the group that did not receive it. Other research suggests that dexamethasone reduces the need for surgery in these cases. It has also been effective for patients with bowel obstruction linked to cancer. Overall, dexamethasone appears to significantly increase the chances of resolving aSBO without surgery.¹²³⁵⁶
