Acute hemoperitoneum after large-volume paracentesis.
Hemoperitoneum resulting from rupture of mesenteric varices is a rare complication of portal hypertension with a high mortality of up to 70%. This case report describes the symptoms, clinical course, and treatment of 4 patients with acute hemoperitoneum caused by mesenteric variceal bleeding after large-volume paracentesis. Abdominal pain and/or hemorrhagic shock developed in 4 patients (age, 48-68 years), admitted for refractory ascites, 3 hours to 4 days after 1-4 large-volume paracenteses (> 4000 mL). Duplex sonography, performed in 3 of the 4 patients before onset of bleeding, showed retrograde flow in the mesenteric veins, suggesting large-caliber mesenteric collateralization. Treatment consisted of surgical ligation followed by transjugular intrahepatic portosystemic shunt (TIPS) (2 patients) and emergency TIPS with embolization of the bleeding vessel (1 patient). One patient died before any intervention could be initiated. In these 4 patients, the concurrence of large-volume paracentesis and hemoperitoneum suggests their causal relationship. The mechanism may be a sudden reduction in intraperitoneal pressure increasing the pressure gradient across the wall of the mesenteric varices, resulting in rupture and bleeding. The awareness of this complication may accelerate the diagnostic process and treatment.
