Physicians need to recognize the potential complications of endoscopic retrograde cholangiopancreatography (ERCP), which are rare but can be serious. We describe a case of post-ERCP subcapsular hepatic hematoma (SHH). A 39-year-old man with a history of alcohol use, complicated by chronic pancreatitis and common bile duct (CBD) stricture, presented with right upper quadrant pain two weeks after the placement of a stent for CBD stricture. He was managed with pain control and antibiotics. SHH is a rare complication of ERCP. Hematomas can expand, resulting in significant anemia and liver function test (LFT) elevation, or can become infected. Patients with SHH must be carefully monitored in the post-ERCP setting.
