11/154. Percutaneous embolization of the distal pancreatic duct to treat intractable pancreatic juice fistula.Pseudocysts and post-necrotic collections of the pancreas are sometimes treated by percutaneous drainage. In cases of post-necrotic collection, intractable pancreatic juice fistula is often formed by disruption of the main pancreatic duct in the necrotized region. We radically treated intractable pancreatic juice fistulae by selective cannulation into the distal pancreatic duct via the route for percutaneous drainage of post-necrotic collections to extinguish the exocrine function of the caudal pancreas. We performed this procedure in two patients in whom the major pancreatic duct was damaged at the body of the pancreas, which was extensively necrotic. Although mild symptoms of acute pancreatitis appeared in both patients after the first procedure, they recovered without severe side effects. Neither recurrence of pancreatic juice fistulae nor reduction of the glucose tolerance was caused by removing the exocrine function of the caudal pancreas in either patient 32 and 24 months after treatment, respectively. This method is an effective treatment modality with which to treat intractable pancreatic juice fistulae with damage of the main pancreatic duct.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
12/154. Percutaneous treatment of a pancreatic fistula after pancreaticoduodenectomy.Breakdown of the pancreaticojejunal anastomosis after a Whipple procedure is reported to occur in as many as 15% of cases. Intraoperative placement of a drain adjacent to the anastomosis is performed to allow the creation of a controlled pancreaticocutaneous fistula in the event of an anastomotic disruption. The authors present a case of successful percutaneous treatment of a disrupted pancreaticojejunal anastomosis. This was achieved with use of the resulting pancreaticocutaneous fistula for access to restore internal drainage, followed by fistula occlusion with use of gelatin pledgets.- - - - - - - - - - ranking = 0.875keywords = fistula (Clic here for more details about this article) |
13/154. Pancreatocolonic fistula due to severe acute pancreatitis: imaging findings.Colonic involvement is an uncommon but potentially lethal complication of severe acute pancreatitis. The spectrum of colonic complications includes localized ileus with "pseudo-obstruction", obstruction, necrosis, hemorrhage, fistula, and ischemic colitis. We report on a patient who developed pancreatocolonic fistulization in the course of protracted severe acute pancreatitis. Emphasis is made on the computed tomographic and water soluble contrast enema findings.- - - - - - - - - - ranking = 0.625keywords = fistula (Clic here for more details about this article) |
14/154. The first histological demonstration of pancreatic oxidative stress in human acute pancreatitis.Necrotizing acute pancreatitis is associated with an inflammatory explosion involving numerous pro-inflammatory mediator cascades and oxidative stress. Acinar oxygen free radical production aggravates pancreatic tissue damage, and promotes cellular adhesion molecule upregulation resulting in leukocyte adherence and activation. The cerium capture oxygen free radical histochemistry combined with reflectance confocal laser scanning microscopy allows the "in situ" histological demonstration of oxygen free radical formation in live tissues. Here we present a case report, where oxidative stress is demonstrated on a histological level for the first time in human acute pancreatitis. A 44-year-old male patient suffering from acute exacerbation of his chronic pancreatitis developed a pancreato-pleural fistula with amylase-rich left pleural exudate causing respiratory compromise. Subsequent to an urgent thoracic decompression a distal pancreatectomy and splenectomy was performed with the closure of abdomino-thoracic fistula. The postoperative course was uneventful, except for a transient pancreatico-cutaneous fistula, which healed after conservative treatment. To carry out cerium capture oxygen free radical histochemistry the resected pancreas specimen was readily perfused with cerium-chloride solution through the arteries on the resection surface. frozen sections were cut, E-, p-selectin, ICAM and VCAM were labeled by immunofluorescence. The tumor-free margin of an identically treated pancreas carcinoma specimen served as a control. Intrapancreatic oxidative stress and cellular adhesion molecule expression were detected by confocal laser scanning microscopy. Numerous pancreatic acini and neighboring capillaries showed oxygen free radical-derived cerium-perhy-droxide depositions corresponding to strong local oxidative stress. Acinar cytoplasmic reflectance signals suggested xanthine-oxidase as a source of oxygen free radicals. These areas presented considerably increased endothelial p-selectin expression with adherent, oxygen free radical-producing polymorphonuclear leukocytes displaying pericellular cerium-reflectance. Modest ICAM upregulation was noted, e-selectin and VCAM expression was negligible. The control pancreas specimen showed minimal oxidative stress with weak, focal p-selectin expression. The development of deleterious pancreatic oxidative stress was based on indirect evidence in human acute pancreatitis. To the best of our knowledge this is the first report demonstrating persistent intrapancreatic oxidative stress histologically in human acute pancreatitis. We have noted p-selectin overexpression with a preponderance in the areas of acinar oxidative stress.- - - - - - - - - - ranking = 0.375keywords = fistula (Clic here for more details about this article) |
15/154. Hemosuccus pancreaticus: diagnosis with CT and MRI and treatment with transcatheter embolization.We report the case of a 56-year-old woman with a presyncopal episode followed by melena. A sentinel clot sign in the pancreatic duct on precontrast computed tomography and the presence of a splenic artery aneurysm on postcontrast computed tomography strongly suggested a fistula between the aneurysm and the duct, as visualized by magnetic resonance imaging. The patient was treated successfully by complete embolization of the splenic artery aneurysm.- - - - - - - - - - ranking = 0.125keywords = fistula (Clic here for more details about this article) |
16/154. Preoperative endoscopic pancreatic stenting for safe local pancreatic resection.Local pancreatic resection and enucleation have the advantage of preserving pancreatic parenchyma but pancreatic fistula often occurs postoperatively. We describe a case in which preoperative endoscopic pancreatic stenting prevented pancreatic fistula formation following local pancreatic resection. A pancreatic stent seems to prevent leakage from small pancreatic branch ducts not identified or ligated intraoperatively, via the pancreatic decompression effect. The present case demonstrates a novel indication for endoscopic pancreatic stenting.- - - - - - - - - - ranking = 0.25keywords = fistula (Clic here for more details about this article) |
17/154. Pancreatic pseudocystportal vein fistula manifests as residivating oligoarthritis, subcutaneous, bursal and osseal necrosis: a case report and review of literature.Pseudocyst is a common complication of pancreatitis. Pseudocyst may rupture into the surrounding organs. rupture into the portomesenteric vein is extremely rare with only seven cases being described in the English literature. pancreatic portal vein fistula is very difficult to verify. The aim of this study was to view the diagnostic methods of pancreatic portal vein fistula and to describe the results of high-dose corticosteroid treatment to our knowledge for the first time. We report here a case of pancreatic portomesenteric vein fistula that was manifest as subcutaneous fat necrosis, bursal necrosis, intramedullary aseptic bone necrosis and recidivating oligoarthritis. The literature of this unusual complication is reviewed. The results of high-dose corticosteroid treatment are also described. In patients with recidivating oligoarthritis, subcutaneous, bursal or osseal necrosis a pancreatic process should be included in the differential diagnosis even in cases of no abdominal signs or symptoms or previous abdominal history. Operative exploration of the pancreas should be performed in the early phase of the disease. To diminish the ongoing extrapancreatic manifestations after the closure of the fistula massive corticosteroid treatment may be attempted although the role of this therapy remains controversial.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
18/154. Sonographic demonstration of a pancreatopleural fistula.Pancreatopleural fistula is an uncommon complication of pancreatitis. The presence of a fistulous tract, although not mandatory for diagnosis of pancreatopleural fistula, has been documented previously with contrast-enhanced radiography and endoscopic retrograde cholangiopancreatography. We report the case of a pancreatopleural fistula with right pleural effusion demonstrated sonographically in a 13-year-old girl with a history of chronic pancreatitis and upper abdominal pain. Sonography also showed a pseudocyst of the pancreas with pleural effusion. The patient was treated conservatively with nutritional support and intercostal drainage of the pleural fluid. Her symptoms resolved and the pleural effusion gradually disappeared. Sonography is useful in confirming the presence of a suggested pancreatopleural fistula and can avoid the need for other, more technically challenging imaging modalities.- - - - - - - - - - ranking = 1keywords = fistula (Clic here for more details about this article) |
19/154. Two cases of thoracopancreatic fistula in alcoholic pancreatitis: clinical and CT findings.We report two patients who were long-time habitual consumers of alcohol and suffered from thoracopancreatic fistula. The first patient, a 52-year-old man with no symptoms, underwent chest CT scan for a medical check-up and was revealed to have left small pleural effusion. A month later, he suddenly experienced severe cough and back pain. The immediate CT scan showed massive pleural effusion and mediastinal pseudocyst, and the amylase level in the aspirated pleural effusion proved to be elevated. He was successfully treated with medication and drainage of the effusion. The second patient, a 39-year-old woman, underwent CT scan for a medical check-up, and it disclosed that she had a small pleural effusion in the left lower thorax. Follow-up CT two months later revealed the pleural effusion to be resolved, however, it demonstrated that a narrow tract derived from the pancreatic secretion located just posterior to the pancreatic tail extended to the mediastinum along the left hemidiaphragmatic crus. She experienced severe cough and sputum four months later. CT scan showed massive pleural effusion in the left thorax and revealed that the pancreaticopleural fistula was located in the same position as the small tract that had been detected by the previous CT scan. The patient received conservative treatment and eventually recovered from the severe chest complications. We consider that asymptomatic left small pleural effusion in these patients who were habitual drinkers is a potential precursor to symptomatic pancreatitis. The patients developed mediastinal pseudocyst and pancreaticopleural fistula in association with chronic pancreatitis within a few months, and therefore intensive follow-up should be undertaken to minimize or prevent chest complications in association with the subsequent symptomatic pancreatitis.- - - - - - - - - - ranking = 0.875keywords = fistula (Clic here for more details about this article) |
20/154. Pancreaticoportal fistula in association with antiphospholipid syndrome presenting as ascites and portal system thrombosis.Fistulous communication between the pancreas and the portal venous system is extremely rare and is usually a complication of chronic pancreatitis or pancreatic pseudocysts. A patient who presented with abdominal pain and ascites secondary to a pancreaticoportal fistula and portal system thrombosis is described. The diagnosis was made by endoscopic retrograde cholangiopancreatography and confirmed by immediate postprocedure computed tomographic scanning. Laboratory studies identified concomitant antiphospholipid syndrome. The patient responded favourably to supportive medical therapy.- - - - - - - - - - ranking = 0.625keywords = fistula (Clic here for more details about this article) |
