  • Intraoperative packing of a pancreatic pseudocyst complicated with bleeding pseudoaneurysm
    Journal of Hepato-Biliary-Pancreatic Surgery, 2004
    Co-Authors: Masashi Watanabe, Haruhiro Nakazaki, Natsuki Tokura, Wataru Takita, Kazuo Kobayashi
    Abstract:

    Hemosuccus pancreaticus (HP) is a rare cause of gastrointestinal bleeding, usually due to rupture of a visceral artery aneurysm in chronic pancreatitis. Other causes of HP are rare. We present a case of HP which occurred in a patient with chronic calcifying pancreatitis and a pancreatic pseudocyst documented by ultrasonography and computed tomography. With detectable fresh blood in the descending duodenum, an aneurysm in the pancreatic head was revealed by Superior Mesenteric Angiography as the suspected origin of intermittent bleeding from the pancreatic duct. Because an artery feeding the pseudocyst could not be identified, angiographic embolization was not possible. Surgical resection or ligation was difficult by laparotomy; therefore, intraoperative packing of the pseudocyst with absorbable gelatin sponges was achieved via a cannula through a directly punctured site in the pseudocyst wall. The patient has been followed for 4.25 years with no further episodes of HP. It is possible that the packing of a pancreatic pseudocyst with gelatin sponges is a method that can be used in similar cases, where control of hemostasis is the primary concern. The packing of a pancreatic pseudocyst with gelatin sponges is a technique that can be performed not only via laparotomy but also via laparoscopy or concomitant Angiography and ultrasonography.

  • Cruveilhier-Baumgarten syndrome in which venous hum disappeared following endoscopic variceal sclerotherapy
    Journal of Gastroenterology, 1996
    Co-Authors: Osamu Yamakawa, Hideki Ohta, Hiroyuki Watanabe, Yoshiharu Motoo, Takashi Okai, Masumi Kadoya, Osamu Matsui, Norio Sawabu
    Abstract:

    We report a case of Cruveihier-Baumgarten syndrome associated with portal vein thrombosis that developed, slowly during a 2-year period after, endoscopic variceal sclerotherapy. The thrombosis led to the disappearance of the venous hum and the dilated abdominal wall veins characteristic of this syndrome. A 73-year-old woman was hospitalized for treatment of esophageal varices in April 1988. Her spleen was markedly enlarged, and the histologic findings of her liver were not consistent with hepatic cirrhosis, but with idiopathic portal hypertension. A venous hum was audible in the upper abdomen. Superior Mesenteric Angiography revealed a porto-systemic shunt vessel under the abdominal wall, originating from the umbilical vein. She was injected four times with a sclerosant, and this brought about disappearance of the esophageal varices. Two years after the first admission, the venous hum was no longer audible, but there was a recurrence of the esophageal varices. More than 2 years later (4 years after the first admission), ultrasonographic study, computed tomography, and Angiography showed a large thrombus, which completely obstructed the portal vein at the origin of the umbilical vein, and the development of collateral vessels, seen as a “cavernous transformation”.

  • Ileal varices associated with recurrent bleeding in a patient with liver cirrhosis
    Journal of Gastroenterology, 1999

    Abstract:

    We report a rare case of massive and recurrent bleeding from ileal varices in a patient with hepatitis C virus-positive liver cirrhosis. A 66-year old woman, who had undergone laparotomy and blood transfusion 36 years before (because of an extrauterine pregnancy) and endoscopic sclerotherapy for esophageal varices 1 year previously, was admitted to our hospital with loss of bright red blood per rectum. The bleeding was massive and recurrent, and frequent blood transfusions were required. Endoscopic studies failed to find the bleeding site. In the venous phase of selective Superior Mesenteric Angiography, Mesenteric varices in the lower part of the abdominal cavity were observed. Laparotomy was performed to control the repeated bleeding which had lasted for more than 1 month. Varices communicating with the right ovarian vein were found on the ileal wall and segmental resection of the ileum was performed. Histological examination demonstrated a massive varicose vein and several dilated veins in the submucosa. The patient's postoperative course was favorable, with no hemorrhagic events during a follow-up of more than 6 months after surgery. Ileal varices should be considered in the diagnosis of a patient who presents with lower gastrointestinal bleeding and portal hypertension.
