Brief Summary:
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.
Detailed Description:
Millions of Americans each year experience adhesion-related small bowel obstruction (aSBO), a condition associated with significant morbidity and prolonged hospitalization. Adhesions formed after previous abdominopelvic surgery can cause twisting of the bowel resulting in injury and a cascade of inflammation that results in progressive bowel wall edema with narrowing of the bowel lumen. This leads to or worsens the bowel obstruction. Reversing this inflammation has the potential to reduce the severity and impact of aSBO, hasten the return of bowel function and avoid an emergency operation to treat the obstruction. Dexamethasone, administered intravenously 2-3 times/day for 5-7 days, has been found effective in patients with a form of SBO related to malignancy (malignant ascites or metastatic disease). A Cochrane review evaluated three RCTs of dexamethasone in patients with malignant SBO and found "evidence that dexamethasone…may bring about the resolution of bowel obstruction" and avoid the need for surgical interventionxx . An underappreciated aspect of these RCTs is that almost all patients had a history of abdominopelvic surgery. Since it is difficult to distinguish the extent to which an SBO is caused by adhesions from prior surgery or mass effect related to malignant ascites or metastases, we hypothesize that dexamethasone may be efficacious in resolving aSBO as well.
The Comparison of Outcomes of Management of Bowel Obstruction (COMBO) study is a double-blinded randomized study of a short course of dexamethasone and supportive care vs. supportive care alone for patients with aSBO. The primary outcome is resolution of SBO without operative management and/or major complications as defined using modified National Surgical Quality Improvement Program (NSQIP) criteria. Differences in secondary outcomes-clinical, healthcare utilization and patient-reported outcomes will be explored overall and across subgroups (e.g., based on severity of aSBO, history of aSBO, sex). Reducing inflammation with dexamethasone- a readily available and safe intervention - may improve the likelihood of non-operative management of aSBO and could change the management of millions of patients with this condition.
