Abstract
Context:
Malignant bowel obstruction (MBO) is a complication of advanced malignancy. For inoperable patients, symptoms are often treated using analgesics, anticholinergics, and anti-emetics. There are, however, few published guidelines for the medical management of MBO.
Objective:
To measure the effect of the combination of dexamethasone, octreotide, and metoclopramide (“triple therapy”) in patients with MBO, compared to patients who received none of the 3 medications (“no drug therapy”).
Methods:
A retrospective cohort study of patients with MBO admitted in a single-center comprehensive cancer center. Patients who received dexamethasone, octreotide, and metoclopramide during their hospitalization for treatment of inoperable MBO were selected for analysis. Patients were excluded if they received a venting gastric tube. Rate of de-obstruction as well as time to de-obstruction were measured.
Results:
There were 20 patients identified who received all 3 drugs of interest, and 29 patients identified who received none of the 3 medications. There was no statistically significant difference in rates of de-obstruction between the 2 groups, though there was a non-significant trend toward patients who received triple therapy were more likely to reach de-obstruction, compared to patients who had no drug therapy (95% vs. 83%, p = 0.379); there was no significant difference in adjusted analysis.
Conclusion:
In patients with inoperable MBO, there was no statistically significant difference in rates of de-obstruction with triple drug therapy compared to patients who received none of the 3 drugs, though the study may not have been powered to detect a difference and further investigation is warranted.
