Among the diverse clinical presentations of gastrointestinal stromal tumor (GIST), spontaneous rupture with peritonitis is extremely rare. We report herein the unusual case of a 75-year-old man found to have a spontaneously ruptured gastric stromal tumor after presenting with generalized peritonitis. The patient was brought to the emergency department of our hospital by ambulance, with generalized severe abdominal pain. On examination, his abdomen was extensively distended with generalized severe rebound tenderness. Abdominal computed tomography scan showed a giant mass arising from the anterior gastric wall with an irregular internal low-density area and a small amount of ascites. An emergency laparotomy revealed a ruptured gastric tumor with dissemination of its necrotic tissue throughout the peritoneal cavity. The tumor was excised together with normal gastric tissue around its base. The tumor, which was 15 x 11 x 4.4cm in size, had a coarse laceration over its well-capsulated smooth serosal surface with massive necrosis and clotted blood inside. Immunohistochemical examination revealed positive reactivity to C-kit protein, which was consistent with the newly introduced diagnostic criteria of GIST. The patient had an uneventful postoperative course and remains well.
We report herein the unusual case of a 59-year-old woman with Plummer-Vinson syndrome who developed gastric cancer. The patient had a longstanding history of dysphagia and iron deficiency anemia, for which she had sporadically taken iron supplements that improved the dysphagia to some extent, but not completely. Owing to her tolerance of the dysphagia, she had not been taking iron supplements for the past 17 years. On admission, she was in fair nutritional condition and not anemic. Blood chemistry results were all normal, including the serum iron level. Gastrointestinal radiographic series demonstrated cervical esophageal webs and advanced gastric cancer. Her dysphagia was successfully treated by endoscopic bougienage through the webs, and a distal partial gastrectomy with nodal dissection was performed. Histology of the resected stomach revealed atrophic mucosal change and, by chance, an adenomatous lesion in addition to adenocarcinoma. Her postoperative course was uneventful and she is now well, without any signs of recurrence. Although Plummer-Vinson syndrome is known to be associated with upper alimentary tract cancers, gastric cancer is extremely rare. A discussion on the etiology of Plummer-Vinson syndrome and its link with potential carcinogenesis follows this case report.
We report a case of anomalous junction of the pancreaticobiliary duct (AJPBD) associated with gallbladder cancer and obstructive jaundice in a patient with high serum and bile cytokine levels. The patient was a 63-year-old woman who complained of right hypochondralgia. Ultrasound, computed tomography, percutaneous transhepatic cholangiography, and endoscopic retrograde cholangio-pancreatatography revealed dilation of the bile ducts, an elevated lesion of the gallbladder, and AJPBD. She underwent percutaneous transhepatic cholangio-drainage (PTCD) for obstructive jaundice. However, the total bilirubin concentration remained high 7 days after PTCD. Her serum interleukin 6 level was 57,359 pg/ml before PTCD, and gradually decreased to 10 pg/ml after PTCD. Bile interleukin 6 level was 10 pg/ml before PTCD, 8997 pg/ ml 3 h after PTCD and gradually decreased there after. Serum and bile levels of tumor necrosis factor alpha and hepatocyte growth factor were high before and after PTCD. The patient underwent an extended cholecystectomy and resection of the extrahepatic bile duct. The resected specimen showed two elevated lesions of the gallbladder which, microscopically, revealed moderately differentiated tubular adenocarcinoma. These findings suggest that pre-existing inconspicuous inflammation of the biliary tract due to reflux of pancreatic juice is involved in elevation of serum and bile cytokines, and that cytokines may participate in gallbladder carcinogenesis associated with AJPBD.
Successful replacements of the superior vena cava (SVC) using autogenous saphenous or superficial femoral vein or prosthetic grafts have been previously performed, but the use of allograft for treatment of SVC syndrome has not been reported. The patient treated by the authors was a forty-one-year-old woman who presented with severe venous congestion of the head and neck caused by fibrosing mediastinitis. In addition, she had sclerosing cholangitis and chronic liver failure. To treat her SVC syndrome and provide access for fluid and blood transfusion and for possible venovenous bypass, SVC reconstruction was performed concomitant to orthotopic liver transplantation. A left innominate vein-right atrial bypass was inserted using an iliocaval allograft. The patient had an uncomplicated recovery, and at six months after surgery her SVC allograft is widely patent and her transplanted liver is functioning well. The venous allograft is an excellent conduit for those patients who are receiving immunosuppression therapy to avoid rejection of a transplanted organ.
The effect of gastrectomy on the subsequent development of esophageal cancer was investigated, focusing on its multicentric occurrence. We retrospectively evaluated 28 patients who underwent subtotal esophagectomy for intrathoracic esophageal cancer between 1985 and 1999. They were divided into two groups according to whether or not they had previously undergone a gastrectomy: group 1, comprising 7 patients who had undergone gastrectomy and group 2, comprising 21 patients who had not. Clinical profiles of the patients were obtained from the medical records and the whole resected esophagus was histopathologically examined. The interval between gastrectomy and esophagectomy in group 1 was significantly shorter in the patients who had undergone gastrectomy for gastric cancer than in those who had undergone gastrectomy for a peptic ulcer, and also in the patients for whom anastomosis had been performed by Billroth I compared with Billroth II. The patients in group 1 were significantly younger than those in group 2. The multiple occurrence of esophageal cancer was found in 4 of 5 patients (80%) in group 1, and in 2 of 18 patients (11%) in group 2, with significantly higher frequency being seen in group 1. More than two coexisting cancer lesions apart from the primary tumor were detected in all four patients. Histological examination of all the coexisting cancer lesions showed well-differentiated squamous cell carcinoma confined within the superficial mucosal layer. No significant differences were noted in the location of the coexisting lesions between the oral and anal side of the primary tumors. Squamous dysplasia was randomly observed, especially around the cancer lesions. These findings suggest that gastrectomy precipitated subsequent chronic gastroesophageal reflux which in turn induced the development of squamous dysplasia and carcinoma at multiple locations in the esophagus.
