PURPOSE : to report 2 rare cases of hemoperitoneum caused by torn greater omentum.
MATERIALS and METHODS : Abdominal ultrasound first , and then abdominal punction and surgery confirmed.
RESULTS : 2 male patients 32-44 y.o were seen with diffuse abdominal pain of 24-48 hours duration. They had no fever, nausea, or vomiting. One had a history of drinking alot of beer the night before .The other had a history of moving house 2 days before .These patients did not remembered abdominal trauma or not. The hematocrite were about 28 - 32 %. Abdominal ultrasound revealed a echo mixed mass at the left upper quadrant and epigastric area , it like cake shape ,and free intraperitoneal fluid liked blood with clotting in the cul-the-sac but failed to revaled a source.
Abdominal ultrasound appeared no sign of broken the liver , spleen , or the kidneys.
So we do a abdominal puntion , the diagnosis of hemoperitonium was made.The emergency surgery confirmed many clots within the torn part of the greater omentum ,and there are no abnormlities detected in the other organs.
CONCLUSIONS : broken greater omentum is a rare case caused hemoperitonium. Emergency abdominal ultrasounds had a suspicion of broken greater omentum in both cases, and followed by an abdominal punction are the management tools for conforming hemoperitoneum. The surgery confirmed many clots within the torn part of the greater omentum in both cases.
