Clinical spectrum, risk factors, management and outcome of patients with retroperitoneal hematoma: a retrospective analysis of 3-year experience

Abstract

<b>Objective</b>: Retroperitoneal Hematoma (RPH) is an underdiagnosed and overlooked disease entity and has a high mortality rate if not diagnosed in a timely manner. This study aims to analyze the clinical characteristics, risk factors, treatment and the outcome of RPH cases at our medical center.<b>Methods</b>: In this retrospective study, all cases who presented to the emergency room (ER) and/or admitted to our center with the diagnosis of RPH from Jan 2016 to Dec 2018 were included (3-year data).<b>Results</b>: A total number of 78 RPH cases were included including both the traumatic and spontaneous bleed. The most common setting was spontaneous bleeding with no concurrent use of anti-thrombotic agents. Zone 3 (pelvic hematoma) bleed was the most common type of RPH. Most patients were successfully managed medically alone (59%). Others required surgical intervention, either laparoscopy, laparotomy or through the interventional radiological approach. There was a significant association between the need for vasopressors (OR-5.65, P-value of 0.039), spontaneous bleed (P-value of 0.001), bleed without antithrombotic agents (P-value of 0.002) with prolonged hospital stay (> 5 days). On follow-up, 83% of cases were reported to be alive. Only 2 patients died secondary to hemorrhagic shock.<b>Conclusion</b>: Most cases of RPH had an excellent outcome with conservative management alone.
