A 49-year-old diabetic patient with abdominal pain was found at ultrasonography and computed tomography to have a cystic mass in the head of the pancreas with dilatation of the main pancreatic duct. The head of the pancreas and the duodenum were removed surgically. Examination of the operative specimen showed chronic pancreatitis, dilatation of the main pancreatic duct, and impacted mucus in the secondary ducts with villous proliferation of the ductal epithelium, thus allowing a diagnosis of intraductal adenomatosis. There was no evidence of malignancy. The resection margin was involved, and consequently the remainder of the pancreas was removed six months after the initial surgical procedure. A review of the literature showed that intraductal adenomatosis tends to spread and carries a high risk of malignant transformation. Surgery is required because of the risk of pancreatic duct obstruction and pancreatic cancer. Intraductal papillary tumour of the pancreas shares many characteristic with other adenomatous proliferation of the gastrointestinal tract (colorectal villous adenoma, bile duct adenomatosis) including the presence of villous structures with increased mucus production, a tendency to spread massively, and a high risk of malignant transformation.

Chemotherapy and radiotherapy offer little benefit to patients with advanced pancreatic cancer. Eicosapentaenoic acid (EPA) has anticancer effects both in vitro and in animal models. The dose of EPA that can be administered to cancer patients has previously been limited by the low purity of available preparations and the tolerability of large capsules. A high-purity preparation of EPA as a 20% oil-in-water diester emulsion allowed a small study of the tolerance, incorporation, and effects of EPA in high doses in five patients with advanced pancreatic cancer. Patients underwent assessment at baseline and every 4 wk thereafter. All patients managed to tolerate a dose providing 18 g EPA per day, with doses between 9 and 27 g daily being taken for at least a month. Dosage was limited by a sensation of fullness, cramping abdominal pain, steatorrhea, and nausea. All such symptoms were controlled by dose reduction or pancreatic enzyme supplements. No other adverse effects attributable to the trial agent were observed. Plasma phospholipid EPA content increased from around 1% at baseline to 10% at 4 wk and 20% at 8 wk. Incorporation of EPA into red blood cell phospholipids reached levels of around 10%. The present study has shown that a novel, high-purity, EPA diester emulsion can be tolerated at a dose providing around 18 g EPA per day with side-effects being easily controlled. The acceptibility of large doses of oral EPA should allow larger controlled clinical studies into potential anticancer effects of EPA.

Pancreas tuberculosis is a rare diagnosis and is usually associated with miliary spread. Only a few cases are reported in the literature. A female patient was admitted with a history of uncharacteristic abdominal pain, weight loss, weakness, and intermittent fever. CA 19-9 was increased and the CT scan showed an irregular mass in the pancreatic tail. Suspecting the diagnosis of pancreatic cancer, a pancreas tail resection with splenectomy was performed. The histological examination showed pancreas tuberculosis. Mimicking pancreatic cancer or presenting with acute/chronic pancreatitis or obstructive jaundice, the diagnosis of pancreas tuberculosis is very difficult to make and is usually established after surgical treatment. Although pancreas tuberculosis is rare, it should be considered when evaluating a pancreatic mass.

Splanchnicectomy has been known for years as a treatment for refractory pain in patients with pancreatic cancer or chronic pancreatitis. We report herein the performance of a videothoracoscopic left splanchnicectomy in a patient with a previous right pneumonectomy who suffered intractable pain from an irresectable left adrenal metastasis associated with metastatic retroperitoneal lymph nodes. Immediate pain relief was obtained, but abdominal pain of middle intensity recurred 6 weeks later. Although infrequently required, this procedure might be of value in some patients with refractory pain.

Lymphoepithelial cyst (LEC) of the pancreas is a rare lesion of undetermined pathogenesis that had been documented almost exclusively in males. The literature on this entity is limited to reports of single or small numbers of cases. Here is presented a clinicopathologic analysis of 12 patients with LEC, 4 of whom were female. The mean age of the patients was 56 years. Four patients presented with abdominal pain and nausea, but in two patients, the cysts were detected incidentally. Only one patient had a history of chronic pancreatitis, and another had a family member with pancreatic cancer. In one patient, a clinical diagnosis of pseudocyst was rendered, and the remaining patients were clinically thought to have cystic neoplasms. None of the patients had any identifiable immunosuppression, HIV positivity, autoimmune disorder (such as Sjogren syndrome) or lymphoma. Seven cysts were located in the head of the pancreas, and 5 were in the tail. The mean size was 4.8 cm (range, 1.2-17 cm). Five LECs were multilocular, three were unilocular; in others, the number of loculi was not recorded. All were "macrocystic" lesions. Two patients had two separate lesions, both in the tail of the pancreas. Histologically, all cases were characterized by cysts, some containing keratin, and lined by mature stratified squamous epithelium surrounded by dense lymphoid tissue, often with prominent follicles. In some areas, the lining epithelium had more cuboidal, flattened, or transitional appearance. Mucinous goblet-like cells were seen in one case. Acute inflammation was not seen. Four cases contained solid lymphoepithelial islands, a feature not previously described in LECs. No squamous metaplasia was identified in the uninvolved pancreatic tissue and no epithelial elements were identified in peripancreatic lymph nodes. In summary, LEC of the pancreas is a rare but distinctive lesion that may be seen in the tail of the organ where most cystic pancreatic neoplasms are encountered. In contrast to the impression from the literature, LECs may also develop in females and, therefore, should be considered in the clinical differential diagnosis of mucinous cystic neoplasms that affect a similar age group. LECs are not associated with the clinical syndromes that are seen with their analogues in the salivary glands.

Paclitaxel and concurrent radiation (paclitaxel/RT) have been evaluated by the Brown University Oncology Group (BrUOG) and the Radiation Therapy Oncology Group (RTOG) in phase I and II studies for patients with locally advanced pancreatic cancer. The dose limiting toxicities were abdominal pain within the radiation field, nausea and anorexia. The phase II Brown University study, utilizing paclitaxel 50 mg/m(2) per week for 6 weeks with 50.4 Gy radiation, demonstrated modest locoregional activity and acceptable toxicity. The median and 1-year survival of paclitaxel/RT in the RTOG phase II study suggests an improvement over previous RTOG studies of fluorouracil (5-FU) and radiation. The addition of gemcitabine to paclitaxel and radiation has also demonstrated promising preliminary activity and a phase II study by the RTOG is being initiated.

We experienced a case of minute pancreatic carcinoma in a 59-year-old man who complained of upper abdominal pain after drinking alcohol. Abdominal ultrasonography (US) revealed dilatation of the main pancreatic duct (MPD). Abdominal computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) showed slight dilatation of the MPD and its obstruction near the portal vein. Endoscopic retrograde cholangiopancreatography (ERCP) demonstrated occlusion of the MPD, and cytology of aspirated pancreatic juice was negative for malignancy. With the diagnosis of benign localized obstruction of the MPD, the patient underwent surgery. There was a clear demarcation of hardness and color of the pancreas on the left margin of the superior mesenteric vein, and the caudal pancreas was hard and fibrotic. Intraoperative US revealed slight dilatation of the MPD, and the aspiration cytology result was class IV. First, segmental resection of the pancreas was performed, but pathological examination of frozen section showed neither malignancy nor stenotic lesion. An additional small portion of the proximal pancreas was resected. The specimen included a ductal carcinoma, 5 mm in diameter. Accordingly, a pylorus-preserving pancreatoduodenectomy was performed. Microscopically, the minute carcinoma had already penetrated the duct wall and infiltrated lymph vessels and veins. The patient has been under close observation at our outpatient clinic, and so far there have been no signs of recurrence. To improve the poor prognosis of pancreatic cancer, we should be alert to the occurrence of acute pancreatitis as an initial symptom.

A 46-year-old woman with a 3-month history of upper abdominal pain was referred to our hospital because of the presence of a pancreatic mass and multiple hepatic nodules on abdominal ultrasonography (US) and computed tomography (CT). We concluded that the patient had pancreatic cancer with multiple hepatic metastases on the findings of endoscopic retrograde cholangiopancreatography (ERCP) and fine needle aspiration biopsy of the hepatic nodule. The patient received gemcitabine treatment. Gemcitabine 1,000 mg/m2 was administered once a week for 3 weeks followed by a week of rest, this constituting 1 cycle of treatment. Partial responses (PR) of both pancreatic and hepatic lesions were observed after the first cycle of the gemcitabine treatment, and serum concentrations of CEA and CA19-9 remarkably decreased. We considered that clinical benefit was obtained because Karnofsky performance status improved and analgesic consumption decreased. Such effectiveness of the gemcitabine treatment lasted for the following 4 cycles. In general, chemotherapy has few effects on an advanced pancreatic cancer. We report a case of advanced pancreatic cancer that could obtain remarkable antineoplastic effect and clinical benefit with gemcitabine treatment.

We have managed four cases of Peutz-Jeghers syndrome (PJS) in children. Fathers of three of these patients had PJS. There was also a family history of cancer in three cases, with pancreatic cancer in a father, colonic and laryngeal cancers in a grandfather, and hepatic and gastric cancers in a grandmother. It is presumed that in each of the cases, the largest polyp was responsible for initial symptoms. Preoperative examination revealed additional small polyps in the whole alimentary tract except for the oesophagus. Patients underwent laparotomy to remove the largest polyps and subsequent intraoperative endoscopic polypectomy for other small polyps, to minimize intestinal resection. Follow-up gastrointestinal examinations, including upper gastrointestinal series, small intestinal contrast study, and barium enema, were repeated about once a year. Three of four cases showed recurrent small intestinal polyps, and one required a second laparotomy because of recurrent abdominal pain. In conclusion, patients with PJS occurring in childhood have a strong hereditary family history of cancer and a high incidence of recurrence. Careful follow-up examination is mandatory for the gastrointestinal tract, as well as other solid organs that are susceptible to malignant change, throughout a patient's life.

The inferior vena cava (IVC) is a retroperitoneal key structure whose location and integrity must be checked in every scan. A number of studies are reported in the literature concerning congenital variations of the inferior vena cava. Anatomical variations of this main venous trunk are relatively infrequent clinical findings during surgery or diagnostic procedures in patients without symptoms such as an aberrant venous drainage or abdominal pain. Among the other imaging techniques, computerized tomography is a non-invasive, effective technique for diagnosing diseases of the retroperitoneal space and, particularly, for detecting anomalies of the main vessels, such as the aorta or IVC, in asymptomatic patients. We present two cases of IVC variation as an incidental finding in patients studied by means of CT scan for the gradation of kidney carcinoma and pancreatic cancer respectively. Two different configurations of the system of the IVC (agenesis of the IVC with hypertrophy of the azygos vein and a double IVC respectively) were found in our cases. The embryological development of the IVC system is discussed, bearing in mind that knowledge of the different variations is important in order to avoid major surgical complications.
