Mesenteric Hematoma: Is there a Role for Selective Management?
Mesenteric hematomas may present as a radiologic finding after blunt abdominal trauma that may be associated with surgically significant mesenteric and/or bowel injury. The question of whether to operate or not to operate on patients with mesenteric hematoma remains a topic of debate, especially with the improved imaging technology. This study sought to identify clinical and radiological characteristics for patient selection for operative management (OM) of mesenteric hematoma. A retrospective review of 33 adults with blunt abdominal trauma and mesenteric hematoma on CT scan (2009-2012) was performed. Patients with other intra-abdominal injuries, penetrating trauma, isolated gastric hematoma, contrast extravasation, extraluminal air, and Glasgow Coma Scale < 14 were excluded. Patients requiring surgical treatment within 24 hours of admission were compared with those who did not using chi-squared test, Fisher's exact test, and t test. Parameters included age, gender, race, Glasgow Coma Scale, vital signs, pain, tenderness, ecchymosis, Injury Severity Score, length of stay, and inhospital mortality. Logistic regression was used to determine positive associations with OM. Of the 33 patients, 19 underwent OM and 14 did not. Both groups were similar at baseline. Regression analysis revealed association for pain [odds ratio (OR) = 9.6, confidence interval (CI) = 1.8-49.9, P < 0.01], tenderness (OR = 32, CI = 4.6-222.2, P < 0.01), and free fluid (OR = 10.3, CI = 1.8-60, P < 0.01) with need for operative intervention. Nonoperative management patients had 100 per cent success rate. Of the OM patients, 100 per cent underwent therapeutic laparotomies. Findings of mesenteric hematoma on CT scan in examinable patients with no abdominal pain, tenderness, or free fluid predict successful nonoperative management.
