Bleeding from duodenal varices is reported to be a catastrophic and often fatal event. Most of the cases in the literature involve patients with underlying cirrhosis. However, approximately one quarter of duodenal variceal bleeds is caused by extrahepatic portal hypertension and they represent a unique population given their lack of liver dysfunction. The authors present a case where a 61-year-old male with history of remote crush injury presented with bright red blood per rectum and was found to have bleeding from massive duodenal varices. Injection sclerotherapy with ethanolamine was performed and the patient experienced a favorable outcome with near resolution of his varices on endoscopic follow-up. The authors conclude that sclerotherapy is a reasonable first line therapy and review the literature surrounding the treatment of duodenal varices secondary to extrahepatic portal hypertension.
Core tip: Bleeding from duodenal varices is a gastrointestinal emergency and focused patient history may help the clinician to suspect this life threatening diagnosis. Clinician’s need to have a high degree of suspicion for bleeding varices even in the absence of known cirrhosis if certain clinical characteristics are present, such as history of crush injury. If duodenal varices are diagnosed on endoscopy, endoscopic injection sclerotherapy can be a highly successful definitive intervention. The authors suggest ethanolamine injection sclerotherapy, though multiple alternative sclerosants are also established in the literature as are other therapeutic alternatives including endoscopic band ligation. With prompt endoscopic management, life threatening bleeding can be effectively mitigated and with the expectation of excellent long term outcomes.
