Pancreatic pseudocyst bleeding associated with massive intraperitoneal hemorrhage.

BACKGROUND: Pancreatic pseudocyst bleeding is an unusual entity of acute abdomen, usually occurring among alcoholics. A high mortality developed in patients with conservative treatment of hemorrhagic pancreatic pseudocyst. We report a 37-year-old male with a pseudoaneurysm in the tail of the pancreas presenting with sudden onset of abdominal pain and swelling. Emergency laparotomy after blood transfusion and fluid resuscitation was successfully performed. METHODS: An abdominal radiography showed multiple calcifications in the epigastric area. Computed tomography of the abdomen showed a cystic lesion with a calcified wall in the tail of the pancreas and a large amount of ascites. After contrast enhancement, there was hemorrhage into the pancreatic pseudocyst with extravasation of contrast into the peritoneal cavity. RESULTS: At operation, active bleeding was noted from a ruptured pseudocyst in the tail of the pancreas and ligation of the bleeding vessel was done. CONCLUSIONS: Hemorrhage into the pancreatic pseudocyst associated with intraperitoneal bleeding is a potentially life threatening condition. Emergency surgical treatment should be carried out as soon as possible.

Hepatic portal venous gas.

BACKGROUND: Hepatic portal venous gas is an unusual entity associated with a variety of abdominal catastrophes. There is usually a grave prognosis when hepatic portal venous gas is associated with ischemic bowel disease. We reported a 57-year-old man with hepatic portal venous gas associated with extensive infarction of the jejunum and a concomitant perforation at a site in the terminal ileum leading to two operations performed 24 hours apart. Progressive ischemia and infarction after the initial laparotomy resulted in massive resection of the small bowel. METHODS: A follow-up abdominal radiography showed progressive dilatation of the small intestine and thickening of the bowel wall. Computed tomography of the abdomen showed pneumatosis intestinalis and gas collection within the intrahepatic and extrahepatic portal vein and superior mesenteric vein and free gas in the peritoneal cavity. RESULTS: At surgery, a long segment of ischemic change of the jejunum with focal necrosis and one perforation in the terminal ileum with no relation to the ischemic area was discovered. These two areas were resected respectively, and anastomosis was performed. Extensive necrosis of the residual bowel was found on the second-look operation performed 24 hours later, and subsequent resection of involved bowel was performed, resulting in a short-bowel condition. CONCLUSIONS: When hepatic portal venous gas associated with ischemic bowel disease is encountered, coexistence of other abdominal condition with no relation to ischemic segment should be considered.
