Hemodynamic Alterations during Laparoscopic Cholecystectomy

Serial changes of hemodynamic parameters were investigated using a Swan-Ganz catheter in 14 patients undergoing laparoscopic cholecystectomy (LAP) and 12 patients undergoing mini-laparotomy cholecyste

Primary mesenteric tumor of adult T-cell leukemia/lymphoma: report of a case.

A rare case of primary mesenteric tumor of adult T-cell leukemia lymphoma (ATLL) is reported. A 64-year-old man was admitted to our hospital after the diagnosis of a palpable ileocecal tumor. Although the serologic test for human T-cell lymphotrophic virus type I (HTLV-I) antibody was positive, neither ATLL cells in the peripheral blood nor systemic lymphadenopathy were observed. At laparotomy, the tumor was histopathologically revealed to be ATLL, and wasalso found to be restricted to the mesentery. An immunohistochemical examination of the tumor tissue using a specific monoclonal antibody was positive for CD2 and CD4, and negative for CD8. Proviral genome integration in the tumor cells was found by Southern blotting using a32p-labeled HTLV-1 probe withEcoRI andPstI digestion. Combination chemotherapy including cyclophosphamide, Adriamycin, vincristine, and prednisolone was begun postoperatively, but the patient did not respond to therapy. Up to now, only two cases of ATLL originating primarily in the abdominal cavity have been reported. These cases all demonstrate the need to consider the possibility of a primary ATLL mesenteric tumor without leukemic manifestation in the peripheral blood.

A case of pancreatic cyst containing gall sludge

SummaryA case of acquired retention cyst of the pancreas containing gall sludge was reported. Gallstones or gall sludge recognized in pancreatic cysts has not been reported. Histological examination suggested that the gall sludge in the pancreatic cyst was caused by the reflux of bile into the pancreatic duct through the papilla of Vater. However, endoscopic retrograde cholangiopancreatography showed no anomalous junction of the pancreatico-biliary ductal system. Crystallization of the components of bile can occur in the pancreas even in a case without anomalous junction of the pancreatico-biliary ductal system.
