Obstruction of the common bile duct (CBD) by direct extension of tumor is occasionally found in patients with hepatic neoplasms. Tumor embolus to the CBD is very rare, however, when no primary hepatic tumor is found. The patient described herein was a 74-year-old man who presented with a new onset of jaundice, nausea, anorexia, and epigastric pain. There was a history of dark urine and clay-colored stools, but no fever. Endoscopic retrograde cholangiopancreatography (ERCP) showed partial obstruction of the common hepatic duct and dilated intrahepatic bile ducts. A computed tomography (CT) scan of the upper abdomen showed no masses. Results of a mesenteric and selective hepatic arteriogram were normal. On abdominal exploration, no tumor was noted. There were no palpable stones in the gallbladder, but a firm mass was felt in the common hepatic duct. Exploration of the CBD produced light-colored debris organized into a cast of the common hepatic duct. Frozen section analysis was negative for tumor cells, but review of the permanent sections confirmed the presence of hepatocellular carcinoma. When non-calculous material is found to be obstructing the CBD, even in the absence of an obvious primary hepatic tumor, tumor embolus or metastasis from a distant site must be considered and the material sent for pathological evaluation.

This is a clinico-pathological report of a 30 years old male patient that presented with acute epigastric pain. Ultrasound examination showed a retroperitoneal tumor, thrombosis of the inferior vena cava and ascites. CAT scan disclosed thrombosis of hepatic vein and inferior vena cava with right atrium involvement. Necropsy showed a leiomyosarcoma of the inferior vena cava. There are seldom reports of this tumor in the last 5 years and an early diagnosis allows therapeutic interventions associating surgery, radiotherapy and chemotherapy.

We carried out a clinicopathologic study on gastric carcinomas excised from 36 young (< 40 years), 34 elderly (61 or 62 years), and 34 aged (> or = 80 years) patients. The young group was characterized by long duration (6.9 months) of epigastric pain (64%), tumor location rarely along the lesser curvature (31%), grossly depressed type in early stage (100%), and histologically undifferentiated type (92%). The aged group was characterized by preexisting disorders (85%), limited lymph node dissection (74%), short operative time (136 min), blood transfusion (74%), tumor location in the lower stomach (59%), and noncurative operation (47%), mainly because of locally advanced disease (59%). The 5-year survival rate in the aged (40%) was much lower than that in the young (72%) and elderly (67%). However, the 5-year survival rate for curatively treated patients did not differ among the young (85%), elderly (81%), and the aged (74%). Thus, gastric carcinomas in the young were mostly of the undifferentiated type resembling peptic ulcers, and resection led to a good prognosis. Aged patients with gastric carcinoma often had preexisting clinical disorders and locally advanced diseases; the limited feasibility of surgical excision sometimes led to a less satisfactory outcome.

Neuroendocrine pancreatic tumors are neoplasms derived from APUD cells, characterized by hyperincretion of several peptides of hormonal activity. The incidence of these tumor is low. They are usually classified according to the predominant secreted peptide: gastrinoma, insulinoma, VIPoma, glucagonoma. Insulinoma is the most frequent endocrine pancreatic tumor, characterized by a peculiar clinical picture due to insulin action. This neoplasm is prevalently benign (90%), and may cause symptoms due to hypo-glycemia such as epilepsy, asthenia, deep coma, dizziness, hunger and epigastric pain. Surgery still constitutes the principal therapy for insulinoma treatment, but an accurate tumor identification is necessary. Selective arteriography of the pancreas and new diagnostic investigations as intraoperative US, selective sampling of pancreatic veins with insulin Quick-RIA, aid the diagnosis and more precise localization of the tumor. When surgical therapy is not practicable, for diffuse metastases, octreotide has an inhibitory effect upon hormone release, and may be combined with chemotherapy for controlling clinical symptoms. We review the clinical records of 2 patients from our Institute, who had hyper-insulinism due to benign insulinomas of the tail of the pancreas. Surgical treatment was performed with enucleation of the neoplasms.

A 41-year-old man was admitted to the hospital complaining of mild epigastralgia. Radiographic examinations revealed a right intrapelvic solid tumor (5 x 3 cm) apparently causing stenosis of the right ureter at the level of pelvic brim. The patient underwent an operation. The tumor which invaded the ileum and ureter was excised with resection of the affected segment of ileum and nephroureterectomy. Histological diagnosis was mesenteric fibromatosis. Barium enema study revealed no polyposis of the colon postoperatively. One year after surgery the patient has no signs of recurrence.

Esophageal diseases frequently cause symptoms such as heartburn, epigastric pain and dysphagia. This article discusses the indications, techniques and limitations of currently available diagnostic procedures. Investigation of symptoms should proceed in a logical stepwise manner, beginning with endoscopy to exclude esophagitis or neoplasia. Symptoms due to acid reflux can be identified by 24h esophageal pH-metry to document a temporal association between symptoms and episodes of esophageal acidification. Stationary or ambulatory manometric recording of esophageal pressures can be used to diagnose esophageal motor disorders such as achalasia, nutcracker esophagus, diffuse esophageal spasm, or dysfunction of the upper or lower esophageal sphincter. Combined 24 h pH-manometry should be used to test the temporal association between pain, reflux, or abnormal motility in patients with non-cardiac chest pain. Video-fluoroscopy is the most appropriate technique to diagnose swallowing disorders. Pulmonary aspiration of gastro-esophageal reflux can be documented with scintigraphy.

We report a case of eruptive metastases to the skin of the face and neck from a hitherto unknown gastric carcinoma, occurring in a fifty-two-year-old man (a regular blood donor), about six months after he contracted human immunodeficiency virus-1 infection. The eruption, consisting of more than thirty pea-sized cutaneous nodules appeared within about twenty days. The patient complained of epigastric pain and weight loss. Histologic examination showed signet-ring cells of gastric carcinoma metastases. Gastroscopic examination showed a widely infiltrating tumor. No metastases were found elsewhere after a careful screening. Immunologic variables were only slightly altered. This case and a brief review suggest that gastric carcinomas, possibly as well as other coincidental tumors, may present atypically during human immunodeficiency virus-1 infection.

Bleeding pseudocysts respectively pseudoaneurysms represents a seldom complication of chronic pancreatitis in owing to erosion of pancreatic or peripancreatic arteries. The potential rupture into neighbouring organs or in the peritoneal cavity is accompanied with paramount life-threatening risks. During the last years we observed 3 patients with acute intestinal bleeding caused by pseudocysts converted to pseudoaneurysms. The goal of our report is to analyze the diagnostic tools and the management of patients with bleeding pancreatic pseudocysts, also well establish the clinical constellation, which is typical for this complication, the best diagnostic tool and the modalities to immediate control of the acute bleeding situation. All three patients suffered from chronic pancreatitis and alcohol abuse. The first patient had a known pancreatic pseudocyst, which penetrated through the gastric wall and caused a life-threatening bleeding. The second patient was admitted in owing to melena. The examinations yielded a pancreatic pseudocyst with hematosuccus pancreatis. The third patient suffered from abdominal pain and vertigo caused by anemia. With endoscopy, Cat and celiacography a pancreatic pseudocyst with cysto-colic fistula has been identified. The color-doppler ultrasound revealed a pseudoaneurysm supplied from a splenic artery branch. With management of these patients with hemorrhagic complications of pancreatic pseudocysts we acquired the following findings: 1. Patients with known chronic pancreatitis and abdominal tumor, especially when accompanied by epigastric pain and anemia, are highly suspicious for pancreatic pseudoaneurysms. 2. The color-doppler ultrasound is the best diagnostic tool, since this investigation can establish the pseudoaneurysm and identify the source.

We reported a case of ALL complicated with acute pancreatitis caused by L-asparaginase (L-Asp). The patient was a 42-year-old man, who showed eosinophilia in peripheral blood and an increase of lymphoblast in bone marrow. He was diagnosed as ALL (L2) and treated by JALSG '87 protocol. Remission induction chemotherapy including L-Asp was administered by 5,000 IU i.v. for 10 days. The day after giving all dose of L-Asp, slight epigastralgia developed and then became severe. After two days, s-amylase was markedly elevated, and the patient was diagnosed as acute pancreatitis caused by L-Asp. He was treated conservatively, but hyperglycemia occurred. The epigastrial tumor was palpable and gradually grew in size. CT-scan and abdominal ultrasonography revealed pancreatic pseudocyst, so he was treated by percutaneous cyst drainage. The patient died of a relapse of ALL. The prophylaxis and early diagnosis of the pancreatitis and hyperglycemia caused by L-Asp are very difficult. We have to examine more cases and pay greater attention to the chemotherapy, including L-Asp.

A rare case of resectable solitary pancreatic metastasis from a renal cell carcinoma is reported. The patient was a 57-year-old man who presented with epigastralgia. He had undergone a radical nephrectomy of the right side 30 months previously. The diagnosis of pancreatic metastasis was based on the patient's past history and angiographic demonstration of typical hypervascular tumor staining. Histological examination was confirmatory. The patient was successfully treated by pancreaticoduodenectomy followed by alpha-interferon administration. As of 6 months after surgery, he remains well.
