A Proposed Algorithm on the Modern Management of Rectus Sheath Hematoma: A Literature Review.

Rectus sheath hematoma (RSH) is a common entity with no clearly established protocol for management. Existing literature on RSH is outdated and does not incorporate modern technological advances in medicine and imaging. A total of 21 studies were included in this literature review based on PubMed and Google Scholar searches. Modern literature was selected from the last 10 years with the inclusion of three past pieces of literature. We performed a literature review to identify the latest research on RSH management and to consolidate an algorithm to help guide modern RSH treatment. Current RSH classification, scoring system, algorithm, and other predictors for treatment plan are discussed. The best RSH management requires early recognition of RSH followed by the appropriate implementation of conservative management and procedural intervention. The decision on picking the treatment of choice is assisted with the use of predictors, such as hematoma size, rate of hemoglobin drop, and the number of blood transfusions. Further studies are needed to clearly establish predictors among the different types of procedural intervention, and we hope the consolidated algorithm on current literature can help promote the standardization of protocol in the future.
