1/148. Metastasis-induced acute pancreatitis in a patient with small cell carcinoma of the lung.Acute pancreatitis in cancer patients can be secondary to the malignant process itself or a complication of antineoplastic agent administration. However, acute pancreatitis caused by metastatic carcinoma of the pancreas is an uncommon condition with a poor prognosis. We report a case of a 63-year-old man with small cell carcinoma of the lung, who developed acute pancreatitis lately. Thirteen months earlier, he developed small cell carcinoma of the lung and received 6 cycles of chemotherapy. Abdominal CT scan showed swelling of the pancreas with multiple masses. The patient was managed conservatively and pancreatitis subsided. This case indicates that metastasis induced acute pancreatitis can be a manifestation of lung cancer, especially in small cell carcinoma.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/148. Hereditary pancreatitis and mutation of the trypsinogen gene.Hereditary pancreatitis is a rare form of chronic recurrent pancreatitis. A family, in which 11 members had chronic pancreatitis, five had diabetes, and two had pancreatic cancer, was studied, and hereditary pancreatitis was diagnosed in all patients by demonstrating the mutation in exon 3 of the cationic trypsinogen gene (R117H). The clinical implications of genotypic analysis in hereditary pancreatitis are discussed.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
3/148. Childhood pancreatitis.Acute pancreatitis is a rare finding in childhood but probably more common than is generally realized. This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. patients with hereditary pancreatitis are at high risk for pancreatic cancer.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
4/148. Nonoperative management of pancreatic pseudocysts. Problems in differential diagnosis.CONCLUSION: The evaluation of pancreatic cystic lesions entails a misdiagnosis risk. awareness of the problem, knowledge of the natural history of these lesions, and meticulous posttreatment follow-up can reduce the consequences of diagnostic errors. If all these precautions are adopted, pancreatic pseudocysts can be safely treated nonoperatively. BACKGROUND: The accurate diagnosis of pancreatic cystic lesions remains a problem. The aim of this study was to ascertain the incidence of and the reasons the diagnostic errors occurred in a series of pseudocysts drained percutaneously and to compare these data to those reported in the literature. methods: Data from 70 patients bearing one or more pseudocysts who underwent a percutaneous drainage were reviewed. The pretreatment workup included medical history, physical examination, ultrasound (US) and computed tomography (CT) scans, amylase assay in both the serum and the cystic fluid, culture and cytology of the cystic fluid. After removal of the drainage, the minimum follow-up period was 12 mo. RESULTS: Four patients died, and two cancer-associated pseudocysts were identified before removal of the drainage. Sixty-four patients were followed up for a mean of 51.9 mo (range 12-154 mo). A third cancer and a mucinous cystic tumor, fully communicating with the main duct, were further detected during this period.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
5/148. Autoimmune pancreatitis, pancreatic mass, and lower gastrointestinal bleed.Autoimmune pancreatitis (AIMP) is a recently described clinical entity causing chronic pancreatitis. It often presents with diffuse enlargement of the pancreas and/or a focal mass at the head of the pancreas causing common bile duct obstruction and jaundice. In most instances, AIMP is mistaken for pancreatic cancer. A number of laboratory abnormalities such as positive antinuclear antibody, hypergammaglobulinemia, and antibody to carbonic anhydrase are often present in these patients. Currently, pancreatic biopsy demonstrating characteristic histopathologic changes is essential to establish the diagnosis. We report the first case of AIMP presenting as a pancreatic tail mass and lower gastrointestinal bleed.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
6/148. Fungal pseudotumor masquerading as pancreatic cancer-a sequela of new technology?Fungal infection resulting in chronic pancreatitis is rare. We report a case of chronic pancreatitis due to fungal infection causing common bile duct obstruction and abdominal pain mimicking pancreatic cancer. Treatment included resection to cure the pain and rule out malignancy. Long-term effects of fungal infection may be seen more frequently as total parenteral nutrition, antibiotics, and foreign bodies (e.g., stents, drains, central venous catheters) are more often being used in the treatment of many diseases.- - - - - - - - - - ranking = 2.5keywords = cancer (Clic here for more details about this article) |
7/148. Management of diagnostic dilemmas of the pancreas by ultrasonographically guided laparoscopic biopsy.INTRODUCTION: Pancreatic lesions may be difficult to diagnose because of small size or inaccessibility. Such lesions are being seen with increasing frequency because of advances in pancreatic imaging techniques. In the past 18 months we have evaluated 14 patients whose pancreatic lesions could not be diagnosed by traditional means, including percutaneous biopsy. methods: With the patient under general anesthesia, the anterior surface of the pancreas was exposed by a three-trocar laparoscopic technique. The lesion was located by laparoscopic ultrasonography. A core biopsy needle was inserted into the lesion under simultaneous visual and ultrasonographic guidance using picture-in-picture techniques. RESULTS: The main diagnostic dilemma encountered was the differentiation of pancreatic cancer from pancreatitis. Other conditions were lymphoma and renal cell carcinoma. Excellent tissue samples were obtained, allowing diagnosis and planning of treatment in all cases. operative time ranged from 1 to 4 hours, and length of stay ranged from 1 to 3 days. blood transfusions were not required, and there were no complications. Alcohol nerve block was performed laparoscopically in one patient in this group after the diagnosis was made by frozen section. CONCLUSIONS: Direct ultrasonographically guided laparoscopic biopsy provides rapid, safe diagnosis of pancreatic lesions.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
8/148. Non-alcoholic duct-destructive chronic pancreatitis: recognition before definitive treatment.Non-alcoholic duct-destructive chronic pancreatitis is a new entity that differs morphologically and pathogenetically from alcoholic chronic pancreatitis. Some clinical and imaging features of this entity resemble those of pancreatic cancer, and hence most of the reported cases underwent pancreatic resections including an invasive pancreaticoduodenectomy. Recognition of this new entity before a definitive treatment is therefore important to avoid an unnecessary pancreatic resection. Recently, we experienced a case of non-alcoholic duct-destructive chronic pancreatitis in an 80-year-old man presenting with obstructive jaundice and whose radiologic features were characteristic as originally described. Recognition of this new entity before definitive treatment enabled us to manage this patient optimally. In addition, the relation between non-alcoholic duct-destructive chronic pancreatitis and chronic pancreatitis with diffuse irregular narrowing of the main pancreatic duct is discussed.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
9/148. Elevated serum creatine kinase activity in a patient with acute pancreatitis.A 62-year-old man presented with a five-day history of a 'flu-like' illness, epigastric pain and a state of increasing confusion. His serum values for amylase and glucose were grossly elevated, as was the creatine kinase (CK) activity, being 23 times above the upper limit of normal. CK-MB was less than 5% of his total CK activity. There was no past history of diabetes or recent history of intramuscular injections or injury. A diagnosis of acute pancreatitis complicated by hyperosmolar non-ketotic (HONK) diabetic pre-coma was made. The patient was treated with intravenous fluids, insulin and subcutaneous heparin. Normal values for serum amylase and CK activity were recorded with convalescence. This case indicates a possible association of a rise in total CK activity with acute pancreatitis complicated by HONK diabetic pre-coma. This observation was made in the absence of clinically evident muscle pathology.- - - - - - - - - - ranking = 0.025394911045127keywords = muscle (Clic here for more details about this article) |
10/148. apoptosis in acute pancreatitis.BACKGROUND: apoptosis may be involved in the mechanism of acinar cell injury in acute experimental pancreatitis. AIM: This study was to investigate whether apoptosis also is involved in human acute pancreatitis. METHOD: A needle biopsy pancreatic specimen was obtained from a patient with acute oedematous pancreatitis. The specimen was stained with In Situ cell death Detection Kit. Similar specimen from a patient undergoing pancreatoduodenectomy for bile duct cancer served as a control. RESULTS: Extended acinar cell apoptosis was found in the pancreatitis specimen. No single apoptotic cell was found in the control pancreas. CONCLUSION: apoptosis probably is involved not only in acute experimental pancreatitis but also in human acute oedematous pancreatitis. The induction and role of apoptosis in pancreatis is discussed based on literature.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
