    Notes: Abstract. Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18–89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy or surgery. Sources of GI bleeding included gastric and duodenal ulcers (n = 7), diverticula (n = 3), erosion of the intestinal wall secondary to malignancy (n = 6), vascular malformations (n = 4), and hemorrhoids (n = 2), as well as from postoperative (n = 6), posttraumatic (n = 2), postinflammatory (n = 4) or unknown (n = 1) causes. Ethibloc (12 cases) or metal coils (14 cases) were predominantly used as embolisates. In addition, combinations of tissue adhesive and gelfoam particles and of coils and Ethibloc were used (six cases). Finally, polyvinyl alcohol particles, a coated stent, and an arterial wire dissection were utilized in one case each. Bleeding was stopped completely in 29 of 35 cases (83 %). In one case (3 %) the source of bleeding was recognized but the corresponding vessel could not be catheterized. In five other cases (14 %) there was partial success with reduced, though still persistent, bleeding. The rate of complications was 14 %, including four instances of intestinal ischemia with fatal outcome in the first years, and, later, one partial infarction of the spleen without serious consequences. Gastrointestinal hemorrhage can be controlled in a high percentage of patients, including the seriously ill and those who had previously undergone surgery, with the use of minimally invasive interventional techniques. The availability of minicoils instead of fluid embolization agents has reduced the risk of serious complications.

    Non-operative management of arterial liver hemorrhages (1999)

    Notes: Abstract. A retrospective evaluation of embolotherapy in patients with arterial liver hemorrhages was carried out. Twenty-six patients, ranging in age from 10 days to 77 years with active arterial liver hemorrhages, underwent non-surgical embolotherapy. Bleeding was attributed to trauma (n = 21), tumor (n = 3), pancreatitis (n = 1), or unknown cause (n = 1). Twenty-nine embolizations were performed via a transfemoral (n = 26) or biliary (n = 2) approach. One bare Wallstent was placed into the common hepatic artery via to an axillary route to cover a false aneurysm due to pancreatitis. Treatment was controlled in 4 patients by cholangioscopy (n = 2) or by intravascular ultrasound (n = 2). Prior surgery had failed in 3 patients. Intervention controlled the hemorrhage in 24 of 26 (92 %) patients within 24 h. Embolotherapy failed in 1 patient with pancreatic carcinoma and occlusion of the portal vein. In 1 patient with an aneurysm of the hepatic artery treated by Wallstent insertion, total occlusion was not achieved in the following days, as demonstrated by CT and angiography. However, colour Doppler flow examination showed no flow in the aneurysm 6 months later. Complications were one liver abscess, treated successfully by percutaneous drainage for 10 days, and one gallbladder necrosis after superselective embolization of the cystic artery. Embolization is a effective tool with a low complication rate in the treatment of liver artery hemorrhage, even in patients in whom surgery has failed.

    Description / Table of Contents: Zusammenfassung. Wir berichten über unsere Erfahrungen an 3 Patientinnen mit einem solid-pseudopapillären Tumor des Pankreas. Charakteristisch für diesen semimalignen Tumor sind das Vorkommen bei jungen Frauen, die auffallende Größe (bis 10 cm) und das seltene Auftreten von Metastasen. Trotz erheblicher Größe der Tumoren war in allen Fällen eine kurative Resektion möglich. Präoperatives Hauptunterscheidungsmerkmal zum duktalen Adenocarcinom war in allen Fällen die normale Weite des Pankreasgangs ohne Gangabbruch. Im Gegensatz zu den meisten anderen Tumoren des Pankreas hat dieser Tumor eine gute Prognose. Alle unsere Patientinnen sind z. Z. (bis zu 8 Jahren nach der Operation) rezidivfrei.
    Abstract: Schlüsselwörter: Solid-pseudopapillärer Tumor – Pankreas – papillär-cystischer Tumor
    Notes: Summary. We report on three female patients with solid pseudopapillary tumors of the pancreas. The histogenetic origin of this entity is still unclear. The tumor, usually occurring in young women, forms large masses (up to 10 cm in diameter) before becoming symptomatic. Metastases have very rarely been reported. In contrast to other pancreatic tumors, the main pancreatic duct was displaced, but of normal caliber without stenosis, in all our patients. Despite the large size of the tumors, they were curatively resected in all three cases. Two of the tumors infiltrated the parenchyma or adipose tissue of the pancreas but did not spread into the lymph nodes or other organs. All of the patients are alive and without signs of tumor recurrence up to 8 years after surgical resection.

    Notes: Abstract  Background: Benign tumors of the pancreas are rare, accounting for only 1–2% of primary pancreatic lesions. Up to now, partial duodenopancreatectomy is still one of the established forms of treatment of benign tumors of the pancreas. We applied duodenum-preserving pancreatic head resection in 12 patients with benign pancreatic tumors to evaluate the feasibility, morbidity and recurrence rates after this less aggressive method. Methods: Between April 1984 and December 1999, 12 patients with benign and borderline tumors of the pancreatic head were operated on by duodenum-preserving pancreatic head resection. Results: All five patients with serous cystadenoma are free of recurrence 4.4 years after primary resection. One of two patients with mucinous cystadenoma and one of three patients with intraductal papillary mucinous tumor developed recurrent tumor within the former pancreatic head 5 years and 6 years, respectively, after the primary operation. Both patients were resected a second time. One of two patients with gastrinoma still has elevated serum gastrin levels. There was no hospital or long-term mortality. Conclusion: For a symptomatic serous cystadenoma, duodenum-preserving pancreatic head resection is a good alternative to partial duodenopancreatectomy. In borderline tumors with malignant potential, we would rather suggest a more radical duodenum-preserving segmental resection. A video clip (3 min) is attached demonstrating the basic steps of duodenum-preserving pancreatic head resection.
