A case of gallbladder cancer manifesting chylous ascites and chylothorax.

A case of gallbladder cancer manifesting both chylous ascites and chylothorax was reported. A 66-year-old man was hospitalized with milky ascites. The patient was diagnosed as having gallbladder cancer based on findings of endoscopic retrograde cholangiopancreatography (ERCP) and celiac angiography. The diagnosis of chylous ascites was confirmed by the presence of microscopically visible free fat and the biochemical analysis of the fluid. The patient also gradually developed chylous thoracic effusion. Autopsy revealed lymphogenous metastasis in multiple retroperitoneal and mediastinal nodes. Chylothorax and chyloperitoneum are relatively rare. Only five cases have been reported in Japan that manifested both conditions.

Hepatic epithelioid hemangioendothelioma: report of five cases.

Results of computed tomography (CT), ultrasonography (US), angiography, and radionuclide imaging were analyzed in five cases of histologically proved hepatic epithelioid hemangioendothelioma (EHE), a rare vascular tumor of adults that has a variable but often long clinical course. All patients received palliative treatment. CT and US were performed repeatedly over a period of up to 53 months. Initial radiologic examination showed two types of hepatic lesions: multiple nodules in both lobes (nodular lesions, n = 2) and large masses with or without calcifications that generally spread along the hepatic margins (diffuse lesions, n = 3). Nodular lesions may be an earlier form of hepatic EHE, as they later gradually changed into the diffuse type. Follow-up CT after treatment showed definite regression of tumors in two cases. In the differential diagnosis, the radiologic findings of diffuse lesions were considered to be specific to hepatic EHE, while those of nodular lesions were nonspecific.

Hypovascular hepatocellular carcinoma undetected at angiography and CT with iodized oil.

Eighteen patients with 22 hepatocellular carcinoma (HCC) lesions less than 2 cm in diameter were examined with conventional angiography, digital subtraction angiography (DSA), and computed tomography (CT) after intraarterial injection of iodized oil (Lipiodol CT). Eight lesions detected at ultrasound examination of eight patients were not identified at conventional angiography, DSA, or Lipiodol CT. At histologic examination, all eight lesions were found to consist of well-differentiated carcinoma of grade I or II on the Edmondson-Steiner scale, and four had fatty change in cancer cells. Percutaneous tissue-core biopsy was indispensable in the diagnosis of well-differentiated HCC lesions that could not be diagnosed with conventional angiography, DSA, and Lipiodol CT.

[Preoperative evaluation of digital subtraction pulmonary angiography in primary lung cancer].

The preoperative evaluation of the resectability for primary lung cancer was studied by using digital subtraction pulmonary angiography (DSA-PAG). Thirty operative cases with primary lung cancer performed DSA-PAG as preoperative test at random for 3 years from June 1985 were subjected in this study. The apparatus used is DSA device (Angiotoron) of a product of Siemens Co., Ltd. The findings obtained by DSA-PAG were retrospectively studied according to the surgical findings, operative modes and postoperative histopathological findings. Moreover, at the same time, usefulness of DSA-PAG was evaluated comparing its findings with preoperative enhanced CT interpretation. The useful findings were obtained in 10 cases of 30 cases (33%). Its contents were 2 cases with invasion of the left atrium, 2 cases with invasion of superior and inferior pulmonary vein, 5 cases with invasion of truncus pulmonary artery and 1 case with interlobar invasion. The findings in all cases were superior to those obtained by the enhanced CT. The decision of operative modes confirming invasion of tumor or metastatic lymph node is one of the important aims of the preoperative test. DSA-PAG can be carried out simply and safely on out-patient basis, additionally, favorable result can be especially obtained in invasion lesions of blood vessels of hilus regions. From the result, informations of regions unknown by preoperative CT were accurately obtained. As a rule, DSA-PAG should be performed by the preoperative routine test of primary lung cancer.

Percutaneous ethanol injection in the treatment of liver neoplasms.

The effectiveness of percutaneous ethanol injection therapy was investigated in 30 patients who had hepatocellular carcinoma (18 had a single lesion and 12 had multiple lesions). In patients who had a single lesion, ethanol injection was especially effective. Histopathologic examination, performed in nine cases in this group, showed that the tumor was completely necrotic in six cases, 90% necrotic in two cases, and 70% necrotic in the remaining case. In eight other cases with a single tumor, follow-up angiography showed complete disappearance of the tumor stain. In the other case, CT showed the nonenhanced low-density area. In the 12 patients with multiple lesions, ethanol injection was performed as part of an integrated treatment plan. Eleven were still alive at the end of the study (the mean follow-up period was 5.8 months). We conclude that ethanol injection may be a valuable treatment for hepatocellular carcinoma.

[Indications for the intra-arterial infusion of urokinase in the treatment of acute intestinal ischemia in patients with heart disease].

The poor prognosis of acute mesenteric artery occlusion can be improved by reaching a rapid angiographic diagnosis and by instituting treatment at an early stage. In addition to operative embolectomy, success may be expected from the use of urokinase infused super-selectively into the superior mesenteric artery. This treatment is only likely to be successful if it is carried out within ten hours of the onset of clinical signs and symptoms. In patients with heart disease, angiography is recommended as soon as there is any suspicion of mesenteric occlusion, in order to confirm the diagnosis, localise the embolus and decide on the form of treatment. Urokinase treatment can be successful for embolic occlusion of the main branches or peripheral branches of the superior mesenteric artery. However, complete occlusion of the main superior mesenteric artery should be treated operatively. A contra-indication to urokinase therapy is occlusion due to infected emboli from an endocarditis.

Bone scanning in patients with breast carcinoma. Should it be a routine examination in every stage group?

Skeletal imaging using radionuclides has proved to be a sensitive method for the detection of early bony metastases from breast carcinoma. Recent studies have found a relatively low rate of abnormal scans in patients with Stage I and II breast cancers, and therefore it is open to question whether bone scanning should be part of the preoperative evaluation of any patient prior to breast surgery. We reviewed our experience with bone scans in 329 patients out of 406 histologically proven breast cancer patients to determine if any or all patients should have this procedure done routinely prior to breast surgery.

Balloon-occluded retrograde transvenous obliteration of gastric varix draining via the left inferior phrenic vein into the left hepatic vein.

We encountered a patient with gastric varix draining not via the usual left suprarenal vein but via the left inferior phrenic vein joining the left hepatic vein. Transfemoral balloon-occluded retrograde transvenous obliteration (BRTO) of the varix was performed under balloon occlusion of the left inferior phrenic vein via the left hepatic vein and retrograde injection of the sclerosing agent (5% of ethanolamine oleate) into the gastric varix. Disappearance of the gastric varix was confirmed on endoscopic examination 2 months later.
