    Recent advances in endoscopic imaging technology have enabled in vivo visualization of cellular level structures in gastrointestinal mucosa. Two types of ultra-high magnifying endoscope-"laser-scanning conf ocal microsccopy series" and "contact endoscopy series (endocytoscopy series) "- that have a maximum magnification power of more than 450 folds have been developed. These novel imaging technologies enable in vivo histological diagnosis of tissue atypia. One of the majon advantages in endocytoscopy is the visualization of cell nucleus, which allows evaluation of cell nucleus atypia. In this report, ECA endocytoscopic tissue atypia classification was reported.

    In pursuit of shortoning of procedure time and a safty and convenient improvement in endoscopic submucosal dissection (ESD) of esophagus, we experimentally produced a transpar ent hood with a mucosa gripping channel attached. An examination of animal studies using mongrel dogs was done. We compared a group to enforce ESD which used this device with a group to enforce conventional ESD which used only a transparent hood and reviewed it. The use of this assistive device has the following advantages. (1) By lifting the separated mucosa, then reversing and pressing it backword, the mucosa-stripped plane can be observed under direct vision. This procedure not only makes hemostasis and blood vessel processing easy, but also perforation difficult to be occurred. (2) Reliable counter-traction can be applied to the submucosal tissue of the stripped plane, and separation time could be shortened. (3) Especially this method of gripping the excised mucosa and attaching the hood to the opening side of the excised reduces the effects of respiration and pulsation, keeps the distance of the separated part and instrument constant and enables safe separation procedure of esophagus. Its utility was confirmed in animal experiments, and it can be expected similar utility in clinical application.

    A 61-year-old man with dysphagia was hospitalized. On esophagography, a symmetrical stenosis about 70 mm in length was found in the lower esophagus. On the proximal side of the stenosis the protrusion was movabile. On esophagoscopy, a type 0-Ip protrusion with white coating and stalk located in the middle portion of the esophagus was noted. Furtheremore, multiple depressed lesions (0-IIc and 0-IIb), which had an irregular shape, as well as erosions were seen throughout the esophagus. On chromoendoscopy using Iodine staining, multiple irregular unstained areas were observed. An esophagectomy with lymphnode dissection was done. On histology, the 0-Ip lesion was composed of poorly differentiated squamous carcinoma cells and spindle cell carcinoma cells with variegation ; the depth of invasion was sm3 (V factor). Typical histological findings of achalasia were observed at the stenosis. An association of poorly differentiated squamous cell carcinoma with spindle cell component which presents as a type 0- I p lesion with esophageal achalasia is very rare.

    We report a case of bezoar fragmented endoscopically by polypectomy snare and clear hood. A 86-year-old woman was introduced to our hospital because of gastric ulcer with large bezoar. Upper gastrointestinal endoscopy revealed a browish bezoar of hen's egg size associated with a gastric ulcer in the antrum. Because the bezoar was large and hard, we failed to break the bezoar by the snare at first. So we attached a clear hood to the top of the endoscope and pull out the snare holding the bezoar. The bezoar was easily broken into half. Repeating on the same process, the bezoar could be crashed into small pieces, and excreted into the stool. Our method of crushing the bezoar is one of the simple and effective treatments.

    On gastroscopy a 49-year-old male was found to have a type IIc+IIa early cancer located in the posterior wall of the upper gastric body. A carcinoid tumor was diagnosed based on the biopsied specimen. Double contrast gastrography showed a depressed lesion with a marginal elevation that resembled early gastric cancer. Endoscopic ultrasound showed a low echoic tumor predominantly located in the 2 nd to 3 rd layer. A diagnosis of gastric carcinoid tumor with an SM2 depth of invasion was maid. Thus, a gastrectomy with lymph node dissection was recommended. However, the patient wished to have the this tumor resected endoscopically . On histological examination of the resected tumor, a typical carcinoid findings with a high degree of atypia and a high Ki-67 labeling index were noted. The severe mucosal atrophy with serum hypergastrinemia endoscopically was confirmed on histology. The serum anti-parietal cell antibody was negative and the patient did not have an anemia. The pepsinogen I/Ii ratio and the serum gastrin level normalized after successful eradication of Helicobacter pylori . It is likely that our patient's sporadic type of type-III carcinoid tumor (Rindi's classification), which occurred due to the presence of severe atrophic gastric mucosa and serum hypergastrinemia induced by Helicobacter pylori infection.

    A 58-year-old woman was admitted in June 2005 with a fever of unknown origin . She had right lower quadrant abdominal pain. CT scan showed a thickened distal ileum wall and mesenteric lymph node enlargement. The differential diagnosis included : Crohn's disease, intestinal tuberculosis, malignant lymphoma, and Yersinia enteritis . On double balloon enteroscopy (DBE), mucosal edema and multiple circular ulcers were found in the distal ileum. On biopsy, a dense infiltration of lymphoid cells and an epithelioid granuloma with Langhans giant cells were noted. The whole-blood interferon-7 assay done using the QuantifFERON (R)-TB2 G test (QFT) was positive. Intestinal tuberculosis was diagnosed. The patient's symptoms improved after anti-tuberculous therapy with isoniazid, rifanpicin, pyrazinamide and ethambutol. DBE and QFT were useful for diagnosing small bowel tuberculosis.

    We report a cencommor case of hemobilia culueb is caused by hepatocellular carcinoma in cessoceation with acute pancreatitis and is sucessfully removed blood clots from the common bile duct (CBD). A 65-year old female with HCV-related liver cirrhosis and hepatocellular carcinoma was admitted to our hospital due to sudden epigastralgia. She had undergone transcatheter arterial embolization for hepatocellular carcinoma one year before. Laboratory tests and abdominal CT on admission revealed acute pancreatitis, which markedly improved by conservative treatment with intravenous administration of protease inhibitors. MRCP revealed filling defects of CBD and ERC also showed a cord-like defects. Subsequently we performed EST and successfully removed a strip of blood clots from CBD. Acute pancreatitis caused by hemobilia from hepatocellular carcinoma is extremely rare. (cencommor)

    Peroral Pancreatoscopy (POPS) is useful especially in the diagnosis of complicated cases with pancreatic stenosis or intraductal opacity as well as intraductal papillary mutinous neoplasm of the pancreas (IPMN). Practically, POPS requires more advanced techniques and need to care much about adverse events after the examination compared to a usual endscopy. Accordingly, both the careful consideration for the proper POPS indication and the acquisition of basic POPS technique is essential. However, POPS procedure is not more than the ERCP technique. Once acquired the basic technique of POPS, examiner should get used to it by the experience with various cases. We intend to describe in this manuscript concerning the basic technique of POPS and the cares about its procedure.
