JOURNAL FREE ACCESSTo identify the muscularis mucosa in the ultrasound image of normal gastric wall, Scanning Acoustic Microscope (SAM) system has been employed to measure the sound speed and the specific acoustic impedance which creates the layer appearance of the gastric wall. Nine stomachs resected were studied by SAM and EUS. The cases were classified into three types depending on their acoustic properties. 1) In cases with no significant difference in the acoustic impedance between the muscularis mucosae (mm) and the lamina mucosa propria (imp), the mm was not distinguishable from the imp by EUS. It was speculated that the mm corresponds to the lower part of the second layer of the five layered appearance of the gastric wall in the endoscopic ultrasound image. 2) When the acoustic impedance in the imp was significantly larger than the mm, a strong border echo was formed between the mm and the imp, the mm layer was not identified. It was speculated that the mm corresponds to the upper part of the third layer of the five layered appearance of the gastric wall. 3) When the difference in the acoustic impedance between the mm and the imp was not large enough to form strong border echo, the mm was visualized as a thin hypoechoic layer between second and third layer.View full abstractDownload PDF (19978K) -

JOURNAL FREE ACCESSA 87-year old female had hypertension and she used Ca-blocker for about 30 years. She developed wheezing during the last 1 year and was treated with teophlline and anti-allergic drug. Bronchial asthma became worser, despite treatment with aminophylline and hydrocortisone. Subsequently, she had wheezing, heart burn, chest pain and appetite loss. Upper gastrointestinal fiber scopy showed ref lux esophagitis. After treatment with proton pump inhibitor, wheezing was controlled and other symptoms disappeared. Sliding esophageal hernia, severe constipation, round back, therapies with Ca-blocker, aminophylline and hydrocortisone were precipitating factors for gastro-esophageal ref lux disease. Gastro-esophageal ref lux may trigger or exacerbate bronchial asthma. We must have a attention to relationship with bronchial asthma and gastro-esophageal reflux.View full abstractDownload PDF (12598K) -

JOURNAL FREE ACCESSA 72-year-old man was operated on due to rectal carcinoma at our hospital in 1993. For the purpose of post operative follow-up, colonoscopic examination was performed annually. He was examined by colonoscopy on July 2, 1997 which showed no abnormalities. He developed a fever in the midnight on that day and visited our hospital. Laboratory data showed elevation of white blood count, CRP, and thrombocytopenia. After admission, abdominal enhanced CT suggested the existence of thrombus in the superior mesenteric vein, and incomplete obliteration of the same vessel was confirmed by abdominal angiography. We diagnosed superior mesenteric venous thrombosis (SMVT) with these findings. The thrombus was reduced in size and the condition of the patient was improved after starting the thrombolytic therapy. SMVT is a rare disease and there are no previous reports as the complication of colonoscopy. In patients presenting with fever or abdominal symptoms and showing laboratory data as stated above SMVT should be considered SMVT as one of the differential diseases.View full abstractDownload PDF (9692K) -

JOURNAL FREE ACCESSA 65-year-old man was admitted to our hospital for discomfort of the left flank. The immunological fecal occult blood testing was positive. A double contrast study of the colon and rectum showed the colonic protruded lesions and a rectal submucosal tumor. Colonoscopy demonstrated polyps of the ascending colon and a protruding lesion with uneven-surfaced mucosa of the rectum. Endoscopic ultrasonography (20MHz probe : Olympus UM-3R) revealed a localized mass, 1 cm in diameter, in the submucosal layer, including a part of the second and third layers, which showed spheric and hypoechoic features with clear border. The internal echo of the mass was nearly uniform, but a part of the mass appeared high echoic features. Endoscopic mucosal resection was performed in order to establish the diagnosis. Path-ologically, the resected tumor was composed of proliferating lymph follicles with germinal centers in the submucosal layer, but lymphocytes of lymph follicles had no atypia and mono-clonality in the immunological staining. We finally diagnosed the tumor as benign lymphoid polyp of the rectum (so-called rectal tonsil). Benign lymphoid polyp of the colon and rectum is a popular disease in Western countries, but comparatively rare in Japan. This case illustrates many problems in diagnosing benign lymphoid polyp, and it seems to be difficult to distinguish benign lymphoid polyp from mucosa -associated lymphoid tissue (MALT) type malignant lymphoma of the colon and rectum as differential diagnosis.View full abstractDownload PDF (12736K) -

JOURNAL FREE ACCESSA 61-year-old woman was admitted to our hospital with complaints of general fatigue and jaundice. She had an elevation of cholestatic enzyme and hypergammaglobulinemia. Laparoscopy showed a coarse undulation and multiple white markings on the liver. Liver biopsy revealed portal expansion and piecemeal necrosis with fibrosis and mononuclear cell infiltration containning plasma cells. Further, in hospital she had hematochezia, and was diagnosed as ulcerative colitis by endoscopic and histological findings. Finally, she was diagnosed as autoimmune hepatitis with ulcerative colitis. Previously reported cases of autoimmune hepatitis with ulcerative colitis in Japan are extremely rare.View full abstractDownload PDF (11759K) -

JOURNAL FREE ACCESSA 47-year-old female with liver cirrhosis complained massive lower gastrointestinal haemorrhage. Urgent colonoscopic examination revealed mucosal elevation with fibrin clot at the middle of ascending colon. Colonic varices were suspected and treated by endoscopic injection sclerotherapy with α-cyanoacrylate monomer. Bleeding was successfully controlled. But after 5month, localized stenosis of injection site occurred, and partial resection of ascending colon was done. Colonic varices treated endoscopic injection sclerotherapy were reported only a few cases before. Further case studies are needed to evaluate its effectiveness in controlling the bleeding colonic varices.View full abstractDownload PDF (20150K) -

JOURNAL FREE ACCESSThe use of expandable metallic stent(EMS)in upper gastrointestinal malignant strictures has been frequently reported. But the report of EMS placement in rectal stenosis is very rare. We experienced the case with EMS placement in the malignant rectal stenosis caused by metastases from prostatic cancer. A 78-year-old man was sent from the department of urology because of difficulty of feces. The examinations of barium enema and colonoscopy showed a stenotic lesion, about 6.2 cm long in the rectum. Pelvic CT scan showed the prostatic tumor invading to the rectum. After the insertion of EMS through the stenosis, the patient could have bowel movements easily. It is suggested that EMS placement in the malignant rectal stenosis would be safe andeffective.View full abstractDownload PDF (13903K) -

JOURNAL FREE ACCESSA 76-year-old woman was admitted to our hospital because of vomiting and diarrhea.Colonoscopy showed various types of ulcers, such as punched-out or longitudinal or cobble-stone like, from the end of terminal ileum to the sigmoid colon. Cytomegalovirus infection wasproved to exist from the biopsy specimen of colonic mucosa and peripheral blood. The patientwas proved to be suffering from disseminated intravascular coagulation and pancytopenia bymeans of virus-associated hemophagocytic syndrome, which have macrophages containingmany kinds of hematocytes in the bone marrow. This is the first case of enterocolitis due tocytomegalovirus infection associated with VANS in a patient without any immunodeficiency.View full abstractDownload PDF (19172K) -
