JOURNAL FREE ACCESSMagnifying endoscopic diagnosis of gastritis was reported by Sakaki for the first time. This classification was consisted from four types, type A (round), B (short line), C (stripe) and D (net) from view point of mucosal pattern. Kim et al. reported the classification of antral mucosa by mucosal pattern. This was consisted from type 1 (pinpoint pits on the flat field) type 2 (regular, trabecular ridge pattern or a regular, flat granular pattern), type 3 (mucosa consist-ing of irregular and coarse granular structure) and type 4 (a prominent clubbing or papillary pattern) from view point of mucosal pattern. As classifications from views of microvessels, the one by Nakagawa et al. and the one by Yagi et al. were reported. The classification by Nakagawa et al. was consisted from regular pattern (R) irregular pattern(I)and obscured pattern (O) and each patterns were compared with histological findings of Sydney system. We had reported Z-classification from views of microvessels and mucosal pattern. We summarized the magnified view of atrophic mucosa and antral mucosa and named it as A-classification. We changed name of Z-classification to B-classification (B ; abbreviation of Body) Furthermore, we combined B-classification with A-classification and made A-B classification, which de-scribed magnifying views of all types of gastric mucosa ; normal, gastritis, atrophic mucosa and intestinal metaplasia.View full abstractDownload PDF (13720K) -

JOURNAL FREE ACCESSBiofilm has been received a great attention in the field of microbiology, because of their potential mechanism of resistance to antibiotics. A biofilm is a complex aggregation of microorganisms marked by the excretion of a protective and adhesive matrix. Biofilms are also often characterized by surface attachment, structural heterogeneity, genetic diversity, complex community interactions, and an extracellular matrix of polymeric substances. Biofilms have been found to be involved in a wide variety of microbial infections in the body, by one estimate 65% of all infections. Infectious processes in which Biofilms have been implicated include common problems such as urinary tract infections, catheter infections, middle-ear infections, formation of dental plaque, gingivitis, coating contact lenses, and less common but more lethal processes such as endocarditis, infections in cystic fibrosis, and infections of permanent indwelling devices such as joint prostheses and heart valves. We have recently documented the existence of biofilm colonies of H. pylori in the biopsy specimens of human gastric mucosa, using scanning electron microscopy (SEM). Further investigation of the biofilm of H, pylori might be required in order to discover the better eradication therapy in the future.View full abstractDownload PDF (9167K) -

JOURNAL FREE ACCESSPrimary duodenal cancer has been increasingly reported with recent advances in imaging techniques. It has been considered that cancers very rarely arise from the duodenal(Brunner's) glands, however, anecdotal reports indicate recent cases in Japan. We report a case with characteristic histopathological findings, which was considered to be duodenal cancer derived from Brunner's glands. A 77-year-old male visited our hospital with a chief complaint of tarrystool. Ulcerative lesions with exposed blood vessels on the posterior wall of the stomach were seen by upper GI endoscopy performed on the same day, and he underwent conservative management. Endoscopic examination was subsequently performed, and 15 mm elevated lesions with depressed surface were confirmed in the descending duodenum. Biopsies of the depressed lesions lead to strong suspicion of adenocarcinoma. After informed consent was obtained, en bloc resection was performed using the strip biopsy method according to the stomach EMR. Histopathological examination of the resected specimen revealed duodenal cancer with sm invasion. Normal Brunner's glands, Brunner's glands hyperplasia, and adenocarcinoYna were mixedely noted by iinmunohistological examination on the resected specimen, therefore duode-num cancer derived from Brunner's glands was suspected, and was considered to be an impor-tart case.View full abstractDownload PDF (13891K) -

JOURNAL FREE ACCESSWe report two cases with rectal carcinoid tumors treated by endoscopic submucosaldissection(ESD)using Hook Knife. Submucosal dissection was performed completely under direct vision with a Hook Knife, because it could separately control the depth and the direction of dissection. Both tumors were removed without any complications. The resected tumors were accompanied by normal surroundings mucosa and normal submucosal tissue. ESD using Hook Knife is recommended as an available treatment in resection of rectal carcinoid tumor, when its size is less than 1Omm and it limits to submucosa.View full abstractDownload PDF (13295K) -

JOURNAL FREE ACCESSHere we reported a case of man in his sixties who presented rectal stenosis due to the invasion of prostatic cancer. He was referred to our hospital with a chief complaint of frequent defecation which had been present for one month. The barium enema showed a circular stenosis of the lower rectum. Colonoscopy revealed luminal stenosis and edematous redness of the rnucosa. Both computed tomography(CT)and magnetic resonance imaging(MRI)revealed an enlarged prostate and an increased thickness of the rectal wall;the border between the prostate and the rectal wall was indistinct. The patient's serum prostate-specific antigen level was high.Rectal biopsy and transrectal needle biopsy of the prostate were done. On histopathology, a poorly differentiated prostatic adenocarcinoma was diagnosed. Thus, the lesion was diagnosed as a prostatic cancer with rectal invasion. The patient had a colostomy and was given hormone therapy. Eight months later, the prostate's volume returened to normal, the rectal stenosis had disappeared, and the PSA had returned to normal. This is a rare case of rectal invasion of prostatic cancer, and highlights the fact that this type of lesion should be in the differential diagnosis of the diffuse type of rectal cancer.View full abstractDownload PDF (14183K) -

JOURNAL FREE ACCESSAn 81-year-old female with diabetes, cerebral infarction, rheumatoid arthritis was admitted to our institation because of diarrhea, hematochezia, and shock. Abdominal ultrasonography demonstrated multiple high-echoic structures in the liver and portal vein. Computed tomogra-phy revealed multiple gas shadows in the portal system and a thickened wall of the small intestine in the pelvis. Blood examination revealed metabolic acidosis and disseminated intravascular coagulation (DIC). Initially diagnosis of hepatic portal venous gas (HPVG) with non-obstructive mesenteric ischemia was made. Endoscopy on 27th hospital day revealed longitudinal, deep, annular ulcers and pseudomenbranous erosions of the sigmoid colon to upper rectum. Biopsied specimen revealed giant cells with including body and CMV-antigenemia was positive. Outcome was favorable after infusion of ganciclovir in addition to intensive treat-ment. A case reported of CMV-colitis with HPVG was rare.View full abstractDownload PDF (13339K) -

JOURNAL FREE ACCESSA 45-year-old man was pointed out abnormality of the liver morphology by ultrasonogra-phy at a medical checkup. Imaging studies by both ultrasonography and CT raised the suspicion of the presence of liver cirrhosis, although the laboratory data was not indicating the presence of liver diseases. We performed diagnostic laparoscopy and found the liver divided into more than eight lobes, although nodular formation was absent on the liver surface. Laparoscopy was a useful examination to differentiate between liver cirrhosis and hepatic anomalous lobation with multiple lobes, which was difficult to distinguish by usual imaging techniques.View full abstractDownload PDF (8498K) -

JOURNAL FREE ACCESSA 70-year-old female was admitted to our hospital for workup and treatment of a 23×16mm mass in the pancreas head. Ultrasonography showed a hypoechoic solid lesion, whereas, abdominal CT revealed a hypervascular tumor with clear boundaries. Endoscopic ultrasonogra-phy demonstrated a hypoechoic mass with lateral shadow and a tiny anechoic lesion. According to these findings, we diagnosed it as endocrine tumor of the pancreas head and performed subtotal stomach preserving pancreatoduodenectomy. The final diagnosis was 'solid-variant type of serous cystadenoma'. When we diagnose a hypervascular and well-demarcated tumor, we need to notice sporadic hyperechoic spots in US, acoustic enhancement in EUS and high-intensity area in MRCP, which seem to represent solid-variant type of SCA.View full abstractDownload PDF (10891K) -

JOURNAL FREE ACCESSIodine staining is mainly performed to screen for superficial esophageal cancer and to evaluate the extent of lesions. The normal esophageal mucosa stained with iodine consisted of aggregations of papillary patterns with small white spots. Changes in the color tone of iodinestain reflect the thickness and degree of damage of the prickle-cell layer, which reacts with iodine. Whitish thickened areas of reflex esophagitis were darkly stained with iodine. Red regions retained their papillary structures and were unstained with iodine and poorly demarcated. Unstained regions suggestive of cancer are characterized by irregular positively stained areas of various sizes within a poorly demarcated unstained region. Dense aggregates of abnormal vessels proliferate up to near the surface. As iodine staining fades, the lesion becomes redder than the surround region, often resulting in positive pink-color signs. Pink-color signs also become positive when papillary vessel proliferation is caused by inflammation. The regions with chronic inflammation and repeated cellular regeneration may be difficult to distinguish from cancer. Basal-layer-type CIS present with poorly demarcated areas unstained with iodine. PC signs are often negative. Papillary structures of different sizes and the formation of poorly demarcated regions can be used to distinguish CIS from inflammatory disease. Iodine staining properties and microvascular patterns should be evaluated to diagnose CIS as well as inflammatory lesions.View full abstractDownload PDF (19189K) -
