Abstract  In cases of paroxysmal nocturnal hemoglobinuria (PNH), attention must be paid to potential complications such as thrombosis and hemolysis due to perioperative stress and infection from complement activation. Here we present the case of a 61-year-old Japanese woman with PNH. We made the diagnosis of PNH when she was 28 years old, and we administered repeated steroid medication and erythrocyte transfusion. The patient's cholecystocholedocholithiasis with a cholecystoduodenal fistula was diagnosed based on a survey of the right hypochondriac pain. We performed endoscopic nasobiliary drainage (ENBD) for the prophylaxis of perioperative infection, plus a cholecystectomy and fistulectomy. There were no complications, including hemolysis attack, infection, thrombosis with irrigation erythrocyte transfusion, steroid cover, or the need for heparin administration during the perioperative period. The reduction of the complement activation is necessary in the perioperative management of PNH patients. The prevention of the development of acidosis and hypoxemia, the selection of washed red blood cells, steroid use, appropriate infection measures and thrombosis prophylaxis are all important for the prevention of complications.

Abstract  Zenker's diverticulum is a very rare disease among gastorointestinal diverticulum. We report a case of Zenker's diverticulum successfully treated with diverticulectomy and cricophalyngial myotomy. A 71-year-old male complained of aspirating water for two years. He was diagnosed as Zenker's diverticulum. Due to his severe symptoms, the operation was performed in an open-neck approach. The left recurrent laryngeal nerve was identified and preserved. An incision was made in the diverticulum wall, and the internal diameter of normal cervical esophagus was measured. The diverticulum was then excised with an automatic suture device in the minor axis direction of the esophagus. A cricopharyngeal myotomy was conducted, because this muscle was fibrotic and stiffened. The patient's symptoms disappeared after the operation. Diverticulectomy and cricopharyngeal myotomy through an open-neck approach is a safe and reliable method that follows, direct access to the diverticulum and recurrent laryngeal nerve.

Abstract The sensitivity and specificity of magnified endoscopic features for differentiating follicular lymphoma from other diseases with duodenal whitish lesions have never been investigated. Here we compared the magnified endoscopic features of duodenal follicular lymphoma with those of other whitish lesions. We retrospectively reviewed the cases of patients with follicular lymphoma (n=9), lymphangiectasia (n=7), adenoma (n=10), duodenitis (n=4), erosion (n=1), lymphangioma (n=1), and hyperplastic polyp (n=1). The magnified features of the nine follicular lymphomas included enlarged villi (n=8), dilated microvessels (n=5), and opaque white spots of various sizes (n=9). The lymphangiectasias showed enlarged villi, dilated microvessels, and white spots, but the sizes of the white spots were relatively homogeneous and their margin was clear. Observation of the adenoma and duodenitis revealed only whitish villi. Although the lymphangioma was indistinguishable from the follicular lymphomas by magnified features, it was easily diagnosed based on the macroscopic morphology. In conclusion, magnified endoscopic features, in combination with macroscopic features, are useful for differentiating follicular lymphomas from other duodenal diseases presenting whitish lesions.

Title Alternative A case of microscopic low-grade appendiceal mucinous neoplasm complicated with appendicitis resected by reduced-port laparoscopic surgery

Abstract Appendicitis is a benign disease for which surgical treatment is widely provided. The complication of neoplastic lesions may be discovered only after resection. However, in some cases, specimens are not submitted to histopathological examination in Japan because of an extreme deficiency of pathologists. We report our experience with one patient who experienced the complication of latent low-grade appendiceal mucinous neoplasm (LAMN) after surgery for appendicitis. Our patient was an 85-year-old woman. Conservative treatment failed to relieve fever and lower abdominal pain and it was decided to treat her surgically. Abdominal computed tomography (CT) showed appendicitis with severe inflammation and suspected adhesion. We decided to explore the abdominal cavity using a reduced-port laparoscopic approach. We found no mucous debouchment or clear tumors in the specimen. Histopathological findings indicated the coexistence of appendicitis and LAMN. At one year and a half after surgery, there was no evidence of the development of pseudomyxoma peritonei. In appendectomy, it is thought that careful perioperative treatment and a postoperative pathological search are important when there are no preoperative findings suggesting a neoplastic lesion.

Abstract Ossified meningioma is classified histologically as a phenotype of metaplastic meningioma, and it is extremely rare. There are only 12 cases involving ossified spinal meningiomas in the literature. We present the case of a 61-year-old female with a primary tumor within the ventral spinal canal at T12. Although we performed a total tumor excision using an ultrasonic bone aspirator, a temporary deterioration of motor evoked potentials (MEPs) was observed during curettage with a Kerrison rongeur. The neurologic findings worsened immediately after surgery. Histologically, the tumor was diagnosed as a metaplastic meningioma with osseous differentiation. In order to avoid spinal cord injury, great care must be taken when removing an ossified meningioma located on the ventral spinal cord.

Abstract A 45-year-old female who presented with loss of consciousness and a cold sweat was found to have a pancreatic tumor and multiple liver metastases. Laboratory studies showed marked hypoglycemia and inappropriately elevated serum insulin, C-peptide, and serum tumor markers. Fine needle aspiration revealed Grade 3 small-cell type primary pancreatic neuroendocrine carcinoma. Consequently, the diagnosis of malignant insulinoma was made. Transarterial embolization (TAE) for hepatic metastases resulted in the reduction of tumor volume and prompt resolution of hypoglycemic attacks, whereas diazoxide and systemic chemotherapy had been ineffective for controlling blood glucose levels, and octreotide was unavailable due to the allergic effect. This case report highlights the potential usefulness of TAE for malignant insulinomas in the management of hypoglycemia.

Abstract Spinal deformity is an important clinical manifestation of Chiari I malformation (CM-I) and syringomyelia. Here we report the result of an 8-year follow-up of a 13-year-old girl with severe scoliosis associated with Chiari malformation and a large syringomyelia. The patient presented at our hospital at the age of 13 with a 68° scoliosis. Magnetic resonance imaging showed Chiari malformation and a large syringomyelia. Neurosurgical treatment involved foramen magnum decompression and partial C1 laminectomy, but the scoliosis still progressed. We present the first case report of a rare course of scoliosis in a patient with CM-I and a large syringomyelia.

Abstract  We encountered a patient with an adult Bochdalek hernia discovered asymptomatically. A 77-year-old Japanese woman visited a local clinic with chief complaints of melena and difficulty in defecation. Based on the results of the detailed examination in our hospital, she was diagnosed with a rectal gastrointestinal stromal tumor (GIST) with a concurrent asymptomatic adult right-sided Bochdalek hernia. Because the tumor was large, laparoscopic abdominoperineal rectal amputation was performed after systemic imatinib therapy. During the surgery, we found a right diaphragmatic defect more than 13cm in long dia., through which the right hepatic lobe, colon, and greater omentum had prolapsed into the right thoracic cavity. No visceral adhesions were noted. No hernia sac was observed. Adult Bochdalek hernia is a relatively rare condition, and only three (incidentally discovered) cases of asymptomatic Bochdalek hernia, including the present case, have been reported in Japan. Here we provide a case report for the patient, who was followed-up without hernia surgery, plus a review of the literature.

Abstract Primary tracheal malignant lymphoma is a rare disease;only 30 cases have been reported to date. A 73-year-old Japanese man with a history of asbestos exposure was undergoing biannual chest computed tomography (CT) twice a year as a routine procedure for those previously exposed to asbestos. He had been smoking since the age of 32. In September 2010, chest CT during this regular checkup revealed a polypoid lesion in his trachea and pleural plaques, which were suspected to be caused by asbestos. Bronchoscopy performed in October revealed a polypoid lesion with granules and nodules in the trachea. A diagnosis of non-Hodgkin lymphoma (NHL) and extranodal marginal-zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) was confirmed by histological analysis of the biopsy specimens. To our knowledge, this is the first case of primary tracheal lymphoma associated with a history of asbestos exposure. Several reports have documented no correlation between asbestos and malignant lymphoma. In addition, the correlation between smoking and NHL is weak. Although we cannot exclude the possibility of a simple coincidence of asbestos, smoking, and tracheal lymphoma, this case suggests that asbestos and smoking might have multiplicative effects in the development or progression of tracheal lymphoma.

Abstract  An 84-year-old man, who had been found to have a submucosal tumor in the ascending colon two years before, was admitted to our hospital for right lower quadrant abdominal pain and melena. An abdominal computed tomography (CT) scan showed intussusception in the ascending colon, resulting from a fat-density tumor. The intussusception was located by colonoscopy. Since the colonic tumor was enlarged in comparison with two years ago and had an ulcer at the top of the tumor, there was the possibility of malignancy and recurrence of intussusception. He underwent a laparoscopy-assisted right colectomy with lymph node dissection. Pathologically, the tumor of the ascending colon was a benign lipoma.
