Arterio-venous fistulas may develop spontaneously, following trauma or infection, or be iatrogenic in nature. We present a rare case of a jejunal arterio- venous fistula in a 35-year-old man with a history of pancreatic head resection that had been performed two years previously because of chronic pancreatitis. The patient was admitted with acute upper abdominal pain, vomiting and an abdominal machinery-type bruit. The diagnosis of a jejunal arterio-venous fistula was established by MR imaging. Transfemoral angiography was performed to assess the possibility of catheter embolization. The angiographic study revealed a small aneurysm of the third jejunal artery, abnormal early filling of dilated jejunal veins and marked filling of the slightly dilated portal vein (13-14 mm). We considered the presence of segmental portal hypertension. The patient was treated with coil embolization in the same angiographic session. This case report demonstrates the importance of auscultation of the abdomen in the initial clinical examination. MR imaging and color Doppler ultrasound are excellent noninvasive tools in establishing the diagnosis. The role of interventional radiological techniques in the treatment of early portal hypertension secondary to jejunal arterio-venous fistula is discussed at a time when this condition is still asymptomatic. A review of the current literature is included.

The case of a patient admitted to hospital for symptoms characterized by upper abdominal pain of pancreatic type associated with vomiting, is discussed. MRI was performed. It documented a focal fluid lesion apparently in communication with the dilated main pancreatic duct showing filling defects. Based on previous radiologic examinations performed elsewhere and MRI findings the diagnostic suspicion was of a cystic lesion. MRI was performed again for re-evaluation and lithotripsy was done; the patient was discharged with the diagnosis of chronic pancreatitis from alcohol abuse.

Groove pancreatitis is a rare form of segmental chronic pancreatitis that involves the anatomic space between the head of the pancreas, the duodenum, and the common bile duct. We report 2 cases of groove pancreatitis with pancreatic heterotopia in the minor papilla. Patients were a 44-year-old woman and a 47-year-old man. Both had a past history of alcohol consumption and presented with abdominal pain, vomiting, and weight loss caused by duodenal stenosis. Abdominal computed tomography revealed thickening of the duodenal wall and enlargement of the pancreatic head in both patients. In 1 patient, ultrasound endoscopy showed a dilated duct in the head of the pancreas. Pancreaticoduodenectomy was performed to rule out pancreatic adenocarcinoma and because of the severity of the symptoms. In both cases, gross and microscopic examinations showed fibrous scar of the groove area. The Santorini duct was dilated and contained protein plugs in both patients, with abscesses in 1 of them. In both cases, there were microscopic foci of heterotopic pancreas with mild fibrosis in the wall of the minor papilla. Groove pancreatitis is often diagnosed in middle-aged alcoholic men presenting with clinical symptoms caused by duodenal stenosis. The pathogenesis of this rare entity could be because of disturbance of the pancreatic secretion through the minor papilla. Pancreatitis in heterotopic pancreas located in the minor papilla and chronic consumption of alcohol seem to be important pathogenic factors.

Feline pancreatitis can be a very difficult disease to diagnose and often requires a combination of clinical suspicion, appropriate physical examination findings, elevations in serum feline pancreatic lipase immunoreactivity, and changes on abdominal ultrasonography consistent with pancreatic disease. The diagnostic difficulties encountered are related to a lack of specific and readily attributable clinical signs in cats. The sensitivity and specificity of the diagnosis of pancreatitis are highest when a combination of tests is utilized; but even when such tests are employed, the diagnosis is still problematic, especially in cats with chronic pancreatitis. Therapy is symptomatic and focuses on maintaining fluid volume, controlling pain and vomiting, preventing infection, and adjusting to changes in the cat's condition as they occur.

A 41-year old alchoholic male with a history of chronic pancreatitis was admitted for nausea, vomiting and weight loss. Angiogram was performed and demonstrated an aneurysmal sac with a narrow neck originating from the inferior aspect of the distal portion of the proper hepatic artery. The origin of the pseudoaneurysm was covered with a 5 mm multiply 2.5 cm Viabahn cover stent (Gore). A repeat angiogram showed some leak and a second stent (6 mm multiply 2.3 cm) was deployed and overlapped with the first stent by 3 mm. Contrast was injected and a repeat angiogram demonstrated complete exclusion of the aneurysm. A repeat computerized axial tomography (CAT) scan of the abdomen after 24 h showed successful stenting. The patient had an uneventful post-operative course.

Seven icteric dogs were determined to have bile duct obstruction secondary to chronic pancreatitis. All dogs had histories of intermittent vomiting and diarrhea. Alkaline phosphatase and alanine aminotransferase activities and total bilirubin concentrations were markedly elevated. Diagnosis was based on exploratory laparotomy and histological examination. Each dog had a 3 to 10 cm mass in the body of the pancreas and obstruction of the common bile duct. Three dogs treated with pancreatectomy, gastrojejunostomy, and cholecystojejunostomy died within five weeks. Three dogs treated with conservative surgical procedures were alive at 8, 16, and 26 months postoperatively. One dog was euthanized because of suspected neoplasia. Hepatic enzyme activity and bilirubin levels decreased markedly in the surviving dogs. Histological examination of the pancreatic masses indicated chronic pancreatitis. Hepatic biopsies revealed evidence of cholestasis. Chronic pancreatitis should be included in the differential diagnoses of icterus, bile duct obstruction, and masses in the pancreas.

A 10-years old girl with chronic pancreatitis, in whom the symptoms of acute pancreatitis appeared after gastroduodenal endoscopy is described. One hour after endoscopy the following symptoms appeared: unigastric and epigastric pain, intense vomiting, elevated amylase activity in the serum (2744 micro/l) and in urine (23738 micro/l) as well as serum lipase activity (4350 micro/l). Ultrasound of the abdomen revealed the enlargement of the pancreas with hypodense structure in comparison to the examination conducted couple hours earlier, and trace of fluid around the pancreas. In the treatment intravenous omeprazole, a strict diet and intravenous fluid and electrolytes were administered. After two days vomiting and abdominal pain subsided, biochemical results improved and the reduction of pancreas dimensions in ultrasound study was observed.

Groove pancreatitis is a rare form of chronic pancreatitis affecting the head of the pancreas localized within the pancreatoduodenal groove. Fibrous scar in this specific topography sometimes makes it hard to differentiate from pancreatic cancer preoperatively. The author reports the case of a 44-year-old man with a long history of alcoholic abuse and experienced intermittent epigastric and nausea vomiting for 2 years. Abdominal ultrasound showed an irregular mixed echogenic mass at the pancreatic head. A computed tomography revealed a poorly enhanced solid mass with small low density cystic areas in the groove, thickening and luminal narrowing of the descending part of the duodenum. Magnetic resonance imaging demonstrated the same mass that was hypointense on T1 weighted images, isointense on T2 weighted images and delayed, progressive inhomogeneous enhancement on dynamic contrast study. MRCP defined a prominent smooth tapering of the common bile duct. Endoscopy disclosed an inflammed sessile mass at the second part of the duodenum. Microscopic examination of the biopsy specimens suggested only chronic inflammation. Then, the patient was treated conservatively and evaluated periodically.

Groove pancreatitis is a segmental chronic pancreatitis that affects the anatomical area between the pancreatic head, the duodenum, and the common bile duct, referred to as the groove area. Most patients with groove pancreatitis are males aged 40-50 years with a history of alcohol abuse. In about 20% of patients undergoing pancreaticoduodenectomy to treat chronic pancreatitis, groove pancreatitis is detected. The clinical symptoms are weight loss, upper abdominal pain, postprandial vomiting, and nausea due to duodenal stenosis. The pathogenesis of groove pancreatitis is thought to be anatomical or functional obstruction of the minor papilla. The viscosity of pancreatic juice increases due to excessive alcohol consumption and/or smoking, leading to calcification of the pancreatic duct. According to these conditions, pancreatitis in the groove area might arise due to impaired pancreatic juice outflow. The descending part of the duodenum is usually stenotic. Severe fibrosis and scarring are evident in the groove area. Characteristic pathological findings are cystic lesions in the duodenal wall, Brunner gland hyperplasia, dilation of Santorini's duct and protein plaques in the pancreatic duct. A differential diagnosis of groove pancreatitis from peripancreatic cancer is clinically important. Cystic lesions in the duodenal wall and smooth stenosis of the bile duct are important findings of groove pancreatitis revealed by endoscopic ultrasonography, computed tomography and magnetic resonance imaging. Biopsy through the duodenum is also useful for diagnosis. Conservative treatment options include endoscopic stenting of the minor papilla, but long-term outcomes remain unclear. Pancreatoduodenectomy is a rational treatment for symptomatic groove pancreatitis.

A severe rare complication in patients with branched-chain organic acidurias (BCOA) is pancreatitis with a limited number of patients published so far. Here, we report on a patient with methylmalonic aciduria (MMA) who developed chronic pancreatitis after several episodes of acute pancreatitis. In addition, an overview is given about some previous published cases with BCOA who developed pancreatitis in the course of the disease. In half of the published MMA patients with pancreatitis, an acute pancreatitis was reported while the rest suffered from a chronic form of this disease. Acute pancreatitis in BCOA patients can clinically present in the context of recurrent vomiting and an impaired general physical condition even without typical signs of pancreatitis. Any form of pancreatitis should be ruled out in the assessment of acutely ill patients with BCOA.
