Use of fibrinolytics for percutaneous drainage of intrabdominal hematoma: a case report.

Background: Intrabdominal hematoma can be managed with angioembolization, surgical drainage, or percutaneous drainage depending on the patient factors, underlying pathology, and size and stability of hematoma. During the past decades, advancements have been made in the percutaneous management of intrapleural fluid collections using fibrinolytics. However, intrabdominal hematoma resolution with the help of fibrinolytic-assisted percutaneous drainage has not been as widely studied as intrapleural fibrinolytics. Our case presents a scenario where effective percutaneous drainage of abdominal fluid collection using fibrinolytics avoided an operative intervention in a patient with a history of multiple abdominal surgeries. This case report in essence can help navigate future studies into exploring non-operative management options in patients with a history of multiple abdominal surgeries.

Case Description: In this report, we present a 51-year-old female status post hiatal hernia repair with jejunostomy tube (J-tube) exchange complicated by walled off intraabdominal hematoma who presented with persistent abdominal pain and leakage around her J-tube. Due to her past history of multiple abdominal surgeries including multiple hiatal hernia repairs, distal esophagectomy with Roux-en-Y, and revision of the said Roux-en-Y complicated by wound dehiscence, surgical drainage was deferred in favor of trialing fibrinolytic administration via catheters. For this purpose, we employed the protocol for fibrinolytic administration used by the Second Multicenter Intrapleural Sepsis Trial (MIST2).

Conclusions: Use of tissue plasminogen activator (t-PA) and deoxyribonuclease (DNase) as per MIST2 protocol was safely replicated for intrabdominal walled off hematoma and resulted in a near complete resolution of the hematoma in 1 week. The patient was eventually discharged with no complications. This case highlights safe and efficacious use of fibrinolytics for non-operative management of intrabdominal hematomas.
