1/89. superior mesenteric artery syndrome simulating acute pancreatitis: a case report.A case of infrapapillary duodenal obstruction secondary to the superior mesenteric artery syndrome is reported. The clinical picture and laboratory data simulated acute pancreatitis but no evidence of pancreatic disease was noted at surgical exploration. A review of the causative factors and treatment of the superior mesenteric artery syndrome is presented along with the differential diagnosis of infrapapillary duodenal obstruction.- - - - - - - - - - ranking = 1keywords = papilla (Clic here for more details about this article) |
2/89. Impacted papilla minor stone in pancreas divisum causing severe acute pancreatitis: a case for early ERCP in acute pancreatitis of unknown origin.This is the first description of severe acute pancreatitis in pancreas divisum caused by a solitary stone impacted in the minor papilla. Recovery was rapid after diagnostic endoscopic retrograde cholangiopancreaticography (ERCP) and endoscopic stone removal. Since other etiological factors accounting for the acute pancreatitis were carefully excluded, it seems that obstruction of the minor papilla by a solitary pancreatic concrement was the most likely cause of acute pancreatitis. This case report demonstrates the diagnostic importance of early ERCP in cases of etiologically unexplained acute pancreatitis.- - - - - - - - - - ranking = 3keywords = papilla (Clic here for more details about this article) |
3/89. Endoscopic retrograde cholangio-pancreatographic diagnosis and extraction of massive biliary ascariasis presented with acute pancreatitis: a case report.This paper reports the case of a young female Thai patient who presented with periodic severe abdominal pains which proved to be acute pancreatitis. Conventional investigations and treatments failed to prove and improve her condition. ERCP was done on the twelfth day after admission. 3 caudal ends of living round worms were noted protruding from the papillary orifice during endoscopy. cholangiography revealed impacted multiple round worms in the common bile duct and both intrahepatic ducts. Endoscopic extraction of the worms was done by using dormia basket and removed with endoscope. Repeated procedure was done 21 times in two and a half hours, obtaining 26 live, mature ascaris lumbricoides varying from 13 to 24 cm in length. Repeated cholangiogram confirmed complete removal of the worms. The patient was relieved from abdominal pain immediately after the procedure, and given oral albendazole 400 mg daily for 7 days. She was discharged asymptomatic 8 days after Ascaris removal.- - - - - - - - - - ranking = 0.5keywords = papilla (Clic here for more details about this article) |
4/89. Spontaneous thrombosis of a pseudoaneurysm complicating pancreatitis.patients with a visceral aneurysm are at high risk for acute transpapillary, intra-, or retroperitoneal hemorrhage, necessitating either surgical or endovascular therapy. We report an instance of spontaneous thrombosis of a pseudoaneurysm complicating pancreatitis before endovascular treatment could be performed. causality and the literature of spontaneous thrombosis in pseudoaneurysms are discussed.- - - - - - - - - - ranking = 0.5keywords = papilla (Clic here for more details about this article) |
5/89. Hemosuccus pancreaticus complicating chronic pancreatitis: an obscure cause of upper gastrointestinal bleeding.BACKGROUND: Hemosuccus pancreaticus, a rare form of upper gastrointestinal bleeding, may complicate chronic pancreatitis and pose a significant diagnostic and therapeutic dilemma. AIM: To present our experience with this potentially life-threatening complication of chronic pancreatitis. methods: We reviewed our experience with management (both operative as well as angiographic embolization) of patients with hemosuccus pancreaticus complicating histologically documented chronic pancreatitis between 1976 and 1997. diagnosis of hemosuccus pancreaticus was based on clinical presentation, preoperative endoscopic and radiographic imaging, operative findings, and pathologic evaluation. RESULTS: During the period, we managed eight patients with hemosuccus pancreaticus (1.5% of all patients with chronic pancreatitis treated surgically). Gastrointestinal bleeding presented as hematemesis in three and hematochezia in three, but all had recent melena and were anemic; three of these patients were hemodynamically unstable. abdominal pain was present in six. When performed, angiography (n=6) was diagnostic of a pseudoaneurysm; computed tomography (n=7) showed a pseudoaneurysm in two and a pseudocyst in five. endoscopy (n=8) revealed blood issuing from the ampullary papilla in two patients. Operative management (n=6) involved distal pancreatectomy, pancreatoduodenectomy, or total pancreatectomy in two patients each. Angiographic embolization was successful in one patient, but the other died from uncontrollable hemorrhage. CONCLUSIONS: Hemosuccus pancreaticus is rare, but should be considered in patients with chronic pancreatitis and gastrointestinal bleeding. In the absence of pancreatitis-related indications for surgery, angiographic embolization can be definitive treatment. If there are pancreatitis-related indications for operation, angiographic embolization may allow an elective operative procedure based on structural changes of the pancreas. If embolization fails, pancreatic resection is usually required, often on an emergent basis.- - - - - - - - - - ranking = 0.5keywords = papilla (Clic here for more details about this article) |
6/89. A case of pancreatic carcinoma with marked ductal dilatation: what contributed to the dilatation?BACKGROUND: We report the case of an 82-yr-old man with invasive ductal carcinoma of the pancreatic head, in which the main pancreatic duct and duct of Santorini were markedly dilated, measuring 1.6 and 1.1 cm, respectively, in diameter on computed tomography. methods: A preoperative diagnosis of ductal carcinoma of the pancreatic head was made, and Whipple's procedure was carried out. RESULTS: Histopathologically, the tumor was diagnosed as moderately differentiated tubular adenocarcinoma, and the resected pancreatic parenchyma showed low papillary mucous cell hyperplasia and atypical hyperplasia in dilated ductular branches. Conclusion. Even among patients with tubular adenocarcinoma, the most common type of pancreatic ductal carcinoma, if the patient is aged and has chronic pancreatitis, the main pancreatic duct and duct of Santorini may dilate to the same degree as in mucin-hypersecreting neoplasm.- - - - - - - - - - ranking = 0.5keywords = papilla (Clic here for more details about this article) |
7/89. Intraluminal duodenal diverticulum causing acute pancreatitis: CT scan diagnosis and review of the literature.BACKGROUND: Intraluminal duodenal diverticulum is a rare congenital anomaly. First described by Boyd in 1845, no more than 100 cases have been reported up to now: only 17 are associated with acute pancreatitis. methods: A new case of intraluminal duodenal diverticulum with acute pancreatitis is reported and the literature about this association reviewed. RESULTS: The diagnosis was made by helical CT scan. The pathogenesis of pancreatitis was possibly due to a pure duodenal content reflux through the papilla of Vater. The patient was successfully treated by surgery. CONCLUSIONS: Intraluminal duodenal diverticulum is a rare but curable cause of pancreatitis, usually affecting young people. We describe, for the first time, its unusual helical CT imaging with two-dimensional reformations.- - - - - - - - - - ranking = 0.5keywords = papilla (Clic here for more details about this article) |
8/89. A case of minute intraductal papillary mucinous tumor of the pancreas presenting with recurrent acute pancreatitis.Intraductal papillary mucinous tumor (IPMT) of the pancreas, a lesion consisting of mucin-producing cells with neoplastic potential, is characterized by duct ectasia, mucin hypersecretion, often extensive papillary intraductal growth, varying degrees of cytologic atypia, and relatively indolent growth. The clinical presentation of IPMT of the pancreas is characterized by chronic or recurrent attacks of abdominal discomfort often in association with low level pancreatic enzyme elevations. Less commonly these lesions may be detected as asymptomatic radiographic abnormalities. Interestingly, a case of a minute IPMT (2 mm in height and 7 mm in length, adenoma) in the main pancreatic duct presenting with acute pancreatitis in a 55 year-old man has been reported in the Japanese literature. Recently, we also experienced a case of a minute IPMT in a branch pancreatic duct causing repeated bouts of acute pancreatitis in a 75 year-old man. A filling defect at the neck of the main pancreatic duct seen on an endoscopic retrograde pancreatogram performed after recovery of the second attack of acute pancreatitis led the patient to undergo an exploratory laparotomy. After a near-total pancreatectomy was carried out, a minute (3 x 7 mm) IPMT of borderline malignancy was discovered in a branch duct at the head portion near the pancreatic neck without any lesions in the main pancreatic duct. Surprisingly, despite the resective surgery the patient died of carcinomatosis 8.5 months after the operation. We herein report a case of a minute but aggressive IPMT of the pancreas with a review of the literature.- - - - - - - - - - ranking = 3keywords = papilla (Clic here for more details about this article) |
9/89. A pancreatic intraductal papillary mucinous tumor causing recurrent acute pancreatitis at the onset of menstrual periods.The unusual case of a young woman with pancreatitis recurring at onset of her menstrual periods is reported. The patient was diagnosed with pancreatic intraductal papillary mucinous tumor (IPMT). The temporal relation of clinical exacerbation of pancreatitis to the menstrual cycle is suggestive of a hormonal-mediated mechanism. The hypothesis of a possible role of progesterone receptors was dismissed with verification of the absence of progesterone and estrogen receptors in the neoplastic tissue. The possible role of activin A or inhibin A in our patient's clinical picture is theorized.- - - - - - - - - - ranking = 2.5keywords = papilla (Clic here for more details about this article) |
10/89. A case of duodenal papillary carcinoma complicated by repeated acute pancreatitis.We present a patient with duodenal papillary carcinoma who repeatedly developed acute pancreatitis preoperatively. The patient was a 65-year-old male. In February 1997, the patient consulted a local hospital due to vomiting, high fever, and jaundice. With the diagnosis of obstructive jaundice, percutaneous transhepatic biliary drainage (PTBD) was performed, revealing a distal bile duct obstruction. Because duodenal papillary carcinoma was diagnosed based on endoscopic findings, the patient was admitted to Kurume University Hospital. Hypotonic duodenography (HDG) disclosed a protruding lesion with an irregular surface in the descending part of the duodenum, resulting in a diagnosis of positive duodenal invasion (du1). Because computed tomography (CT) demonstrated a protruding lesion on the medial side of the second portion of the duodenum, positive pancreatic invasion (panc2) was diagnosed. On March 18 and April 22, sudden abdominal pain, leukocytosis, and an increase in serum amylase were noted. CT revealed that the pancreas was diffusely enlarged, showing an ill-defined boundary between the pancreas and adipose tissue and fluid collection. On CT, the lesion was evaluated as Grade 3 and moderate. For treatment, pancreatic enzyme inhibitors and antibiotics were intravenously injected. Peritoneal perfusion was concomitantly performed during the second treatment. Because symptoms remitted thereafter, a pylorus preserving pancreatoduodenectomy (PpPD) was carried out. The postoperative histologic examination revealed negative pancreatic invasion. Concerning the etiology of acute pancreatitis, not pancreatic invasion, but impaction of the liberated tumor mass in the common canal was considered responsible for the repeated pancreatitis because the tumor showed a cauliflower-like shape.- - - - - - - - - - ranking = 3keywords = papilla (Clic here for more details about this article) |
