Acute abdominal pain in chronic hemodialysis patients has well-known causes
, including acute pancreatitis, mesenteric arterial insufficiency, or compl
icated duodenal ulcer. Others, such as hemoperitoneum, are far less common.
Although hemoperitoneum occurs in patients receiving peritoneal dialysis,
dialysis is seldom it ever the direct cause of the bleeding. Hemoperitoneum
is often related to menses or ovulation, particularly to ovarian cyst rupt
ure; therefore, it is more common in young women. In most cases, no specifi
c treatment is required. Hemoperitoneum is rarely considered as the cause o
f acute abdominal pain in chronic hemodialysis patients. In this report of
hemoperitoneum confirmed by emergency laparotomy in 3 women, bleeding was n
ot related to gynecologic origin. All of the women were younger than age 50
and undergoing long-term hemodialysis. All patients had a history of acute
abdominal pain associated with shock. The cause of bleeding was always an
organ lesion: hepatic amyloidosis with suspected portal hypertension or scl
erosing peritonitis and acute hemorrhagic pancreatitis. Coagulation abnorma
lities and the use of anticoagulants during hemodialysis sessions may have
been aggravating factors in all three patients. Hemoperitoneum is difficult
to diagnose, particularly in the minor forms, and consequently its inciden
ce may be underestimated. Therefore, it should be considered whenever a chr
onic hemodialysis patient presents with persistent acute abdominal pain. (C
