JOURNAL FREE ACCESSWe reviewed on clinical usefulness of narrow band imaging (NBI) colonoscopy in improvement of detection of neoplasia, differential diagnosis between neplasia and nonneoplasia, pit pattern diagnosis, histological atypia and invasion depth diagnosis of colorectal neoplasia. At present, NBI is commonly considered to be useful in differential diagnosis between neplasia and non-neoplasia & pit pattern diagnosis for regular pit without chromoendoscopy. Furthermore, NBI magnification is expected to be useful in histological atypia and invasion depth diagnosis through the detection of thick/irregular vessels and its distribution on the lesion surface. Advantage of NBI magnification is to be able to achieve the diagnosis without chromoagents. Further detailed study and critical discussion are needed to establish a practical classification of NBI magnification findings for histological atypia and invasion depth diagnosis of colorectal tumor.View full abstractDownload PDF (15534K) -

JOURNAL FREE ACCESSA 76-year-old-man underwent EGD, and it revealed an elevated lesion, most of which was covered by duodenal mucosa with irregular central depression in the duodenal bulb. Well differentiated adenocarcinoma was suggested histopathologically from biopsy specimen. Therefore segmental resection of the duodenum was performed. Histologically, well differentiated adenocarcinoma arose within the background mucosa consisted of foveolar epithelium and fundic glands. Immunohisto-chemical examination was performed, and both the cancerous region and background mucosa were positive for MUC5AC and MUC6. Thus, this tumor was considered to be derived from ectopic gastric mucosa in the duodenal bulb. We report here a case of early primary carcinoma of the duodenal bulb arising from ectopic gastric mucosa.View full abstractDownload PDF (10684K) -

JOURNAL FREE ACCESSA 27-year-old woman was admitted to our hospital because of recurrent rectal bleeding since her birth. She was diagnosed as having diffuse cavernous hemangioma of rectum by using plain abdominal X-ray, computed tomography (CT), magnetic resonance imaging (MRI), and colonoscopy. In addition, we also employed fat-suppression MRI, resulting in a usefulness for the differential diagnosis because it could figure out the structure of diffuse cavernous hemangioma of the rectum. She had been followed up for about 10 years, and the surgical resection of the rectum was performed in April, 2006 because of uncontrollable anemia. Macroscopically, the perirectal fat was much thicker than usual, and the cavernous hemangioma extended from the rectosigmoid colon to the rectum below the peritoneal reflection. The serosal surface of the perirectum was covered with hemangiomatous tissues and phleboliths, and the mucosal surface of the rectum was congestive and extremely edematous. Histological examination showed diffuse cavernous hemangiomas in association with calcification extending from the mucosal layer to the subserosal layer. No sign of recurrence has been observed during the follow-up period after operation.View full abstractDownload PDF (11616K) -

JOURNAL FREE ACCESSA 73-years-old woman was admitted to our hospital with chronic diarrhea and hematoch ezia. Colonoscopic examination revealed flat reddish polyps in the rectum and sigmoid colon. Biopsy specimen demonstrated that superficial erosion with the fibrinopurulent exudate, large elongated glands and granulation tissue on the surface. A diagnosis of cap polyposis was made. After the administration of predonisone enema symptoms improved immediately. We tapered predonisone enema in further about 10 months and she has been free from symptoms for 18 months after the cessesion of therapy. In high iron diamine-alcian blue (HID-AB) staining, the mucin produced by the glands was sialomucin predominant at first, while after the therapy sulfomucin had gradually appeared in the deep area of the musosa. So HID-AB staining is useful for evaluation of charactenistics of CP.View full abstractDownload PDF (12056K) -

JOURNAL FREE ACCESSA 44-year-old man with ulcerative colitis (UC) was treated with salazosulf apyridine (3g/day) since first being diagnosed 16 years earlier. He had a good clinical course. On routine colonoscopy done in October 21, 2003, multiple round elevated lesions with a smooth surface located in the ascending colon and the hepatic flexure were found . The patient was diagnosed as having pneumatosis cystoides intestinalis (PCI).View full abstractDownload PDF (10935K) -

JOURNAL FREE ACCESSA 76-year-old female was admitted to our hospital for a second remnant colon cancer operation. On gastroduodenoscopy, a fistula at the lesser curvature of gastric lower body was noted. The endoscope could be inserted through the fistula into the main pancreatic duct, which was enlarged due to the presence of a massive mucine. A papillary tumor was detected at the inner lumen of the main pancreatic duct. A distal pancreatomy was done. On histopathology, IPMN was diagnosed.View full abstractDownload PDF (11079K) -

JOURNAL FREE ACCESSWe performed endosonography-guided biliary drainage (ESBD) as preoperative decompression of the bile duct in a case of obstructive jaundice. A 73-year-old woman was admitted to our department due to obstructive jaundice caused by pancreatic head cancer. Endoscopic biliary drainage (EBD) was unsuccessful because of the tight stricture of the distal bile duct. ESBD was carried out successfully via the upper duodenal angle with a 7F plastic stent. Her hepatobiliary enzyme levels showed an immediate decline and pancreaticoduodenectomy was performed uneventfully. No complications relevant to ESBD were encountered in this case. ESBD is, even in preoperative settings, a useful method of biliary drainage in cases with difficult EBD and may replace percutaneous transhepatic biliary drainage.View full abstractDownload PDF (9277K) -

JOURNAL FREE ACCESSTranspapillary intraductal ultrasonography (IDUS) is especially useful for preoperative evaluation of the extent of bile duct cancer and for assessment of small stones in the bile duct. It is usually easy to insert a microscanner (MS) with a guide wire channel into the common bile duct without endoscopic sphincterotomy (EST), and is possible to introduce it into the right and left intrahepatic bile ducts. It is important to well understand the orientation of the bile duct and its surrounding organs, which allows reduction of fluoroscopy and examination time. IDUS should be performed before EST and biliary drainage since these procedures induce an artifact of wall thickening of the bile duct, which interfere with preoperative evaluation of the longitudinal extent of bile duct cancer.View full abstractDownload PDF (20195K) -

JOURNAL FREE ACCESSEndoscopic biliary drainage (e.g. endoscopic biliary stenting [EBS]) is the treatment of choice in the management of obstructive jaundice due not only because of its lesser invasiveness and greater safety as compared with surgical drainage or percutaneous transhepatic biliary drainage (PTBD), but also due to its ability to maintain the physiological flow of bile. EBS, however, is not always possible, and surgical drainage or PTBD have been performed in such cases with difficult cannulation of the bile duct or difficult intubation of the duodenum with a duodenoscope during endoscopic retrograde cholangiopancreatography (ERCP). Recently, the role of endoscopic ultrasonography (EUS), or endosonography (ES), has expanded from simply obtaining cross-sectional images of the gut wall or surrounding organs and tissue samples by fine-needle aspiration cytology/biopsy to therapeutic applications. Endosonography-guided biliary drainage (ESBD) is one of such therapeutic applications of ES and reports on this procedure are increasing. In the present article, technical aspects and the current status of ESBD are discussed. As in EBS, ESBD makes it possible to recover physiological bile flow without pain following the procedure. Therefore, ESBD is expected to soon be widely accepted as a new option for difficult cases of not only EBS but also PTBD with obstructive jaundice, and may become the treatment of choice in selected cases. Development of relevant devices will expand its indications and accelerate its spread.View full abstractDownload PDF (13275K) -
