JOURNAL FREE ACCESSStereomodel of depressed early gastric cancer was constructed using an H. E, stained specimen which was obtained at surgical operation. We used card size-photographing of the cancer and the adjacent lesion and traced emphatically the cancer and fibrotic lesion and three-demensional examination was performed by stereo-rearchitecting, using the three-dimensional architecture system [TRI] (RATOC CO., LTD.) .
These make us to calculate cancer body volume and fibrotic volume possible. The mobility and flexibility (hereinafter referred to as “movement”) of the mucosal surface of the cancer and the adjacent lesion were observed by endoscopy, and there were gradated and converted into marks. The markes was conf rontated as to the depth of cancerous invasion, cancer body volume or fibrotic volume according to the Stereomodel, locational relationship between cancer body and fibrotic location⋅density in the submucosal layer, etc., and the “movement”. As a result, m cancer tended to have less cancer body volume and fibrotic volume compared with sm cancer, but there was no significant difference. No correlation was noted between cancer body volume or fibrotic volume and the “move-ment”. On the other hand, significantly worse “movement” (P<0.05) was noted for deeper cancerous invasion, depth of fibrosis. Also, worse “movement” was noted for lesions with high density of thick fibrosis extensively and higher ratios of fibrotic volume to lesional volume (cancerous area+fibrotic lesion) .View full abstractDownload PDF (6328K) -

JOURNAL FREE ACCESSIn order to clarify the relationship between HCV status (genotype and titer of HCV-RNA) and peritoneoscopic findings in chronic hepatitis C (CHC), 50 patients were studied (HCV genotype II: 30 patients, III: 14 patients and II+III:6 patients) . There were no significant differences in the incidence of Shimada's code number (200, 300), reddish marking (RM) and patchy marking (PM) among three groups with HCV genotype II, III and II+III. The number of patients with RM and PM was 4, those with PM alone was 8, those with RM alone was 8, and those without RM or PM was 30. The HCV-RNA titer of patients without RM or PM was signicantly lower (P< 0.05, P< 0.01, P< 0.01, respec-tively) than that of other groups. The HCV-RNA titer in patients with sublobular hepatic necrosis (SN) was significantly higher than that without SN (P< 0.05) . Among patients with SN, HCV-RNA titer in patients with PM and/or PM was signicantly higher (P< 0.05) than that without RM or PM, and it showed significantly lower (P< 0.05) complete response rate by IFN therapy than that in patients with non-SN without RM or PM. These data suggest that RM and PM reflect the high titer of HCV-RNA in CHC and useful for predicting the effect of IFN therapy.View full abstractDownload PDF (559K) -

JOURNAL FREE ACCESSOperated ulcer tissue specimens from five gastric ulcer and six duodenal ulcer patients were analysed to show whether the tissue contained 'activated' eosinophils. The specimens showed various numbers of eosinophils in the bottom and edge of ulcer tissue. Most of these eosinophils stained clearly with degranulation by immunohistochemical study with monoclonal antibody EG2 (for the secreted form of eosinophil cationic ptotein), indicating that they were activated eosinophils. Repeated biopsy specimens from eleven patients with various stages of gastric ulcer showed infiltration of 'activated' eosinophils and there were no difference between specimens from easily healed ulcers and from non-healed ulcers. However, activated eosinophils play important roles in many diseases by their potency of tissue injury. The role of 'activated' eosinophils in gastroduodenal ulcer tissues i not clear but it should be noteworthy.View full abstractDownload PDF (6348K) -

JOURNAL FREE ACCESSWe attempted to obtain the three-dimensional (3-D) CT scan findings of rectal carcinoma with use of helical scanning by using the air as a contrast medium. We investigated whether the 3-D CT colonoscopy was useful for diagnosis of rectal disease and mass screening of colorectal carcinama, comparing with colonoscopy images. The modality used was TCT-900S. Axial images were taken with an interslice gap of 5mm, 5mm/sec table speed, and 1mm reconstruction intervals. About 70-80 axial images of around rectal carcinoma in cross-section were employed to obtain the 3-D voxel image data. Air was insufflated from the anal to extend the colon wall and to provide a contrast medium. In abdominal study 3-D recognition of the colon wall and carcinoma structure was well visualized and could help to grasp the structures of rectal carcinoma. Further-more, this method has several advantages as follows; 1) invasiveness, 2) little physical burden for patients and 3) little dependence of the examination technique ability. There-fore, with the progress of computer, three-dimensional CT colonoscopy could be applied for mass screening of colorectal carcinoma in future potential.View full abstractDownload PDF (11619K) -

JOURNAL FREE ACCESSA case of early primary adenoid cystic carcinoma of the esophagus was reported. A 59 year- old male had a tumor in the esophagus which revealed at endoscopy. The biopsy specimens and the findings of endoscopic ultra songraphy suggested the adenoid cystic carcinoma. Subtotal esophageal resection was dome. Esophageal adenoid cystic car-cinoma is an infrequent malignancy of the esophagus, eighty-one cases have been reported in the literature. In this case, we could make pre-operative diagnosis by the biopsy specimens and the findings of endoscopic ultra sonography. Since tumor invasion remained within the submucosal layer, he may survive longer.View full abstractDownload PDF (8707K) -

JOURNAL FREE ACCESSA 53 year old woman was admitted to our hospital with complaints of dysphagia. Esophagogram revealed a polypoid lesion with irregular nodular surface in the Ei portion of the esophgus. This was surrounded by slightly elevated granular lesions with slightly depressed areas. Esophagoscopic examination showed a polypoid lesion surrounded by reddish and coarse mucosa. Iodine method showed unstained area of these lesions located from 31 cm to 37 cm from the incisor teeth. Endo-ultrasonographic picture showed polypoid lesion to be well defined very low echoic area in the second and upper third layer. This image was similar to that of leiomyoma arising from muscularis mucosa. As this tumor was suspected of carcinosarcoma of the esophagus, the subtotal esophagectomy was carried out. Histological and immunohistochemical studies of the surgical specimen revealed so-called carcinosarcoma of the esophagus. The tumor was 35×45 mm in size and invaded into the submucosal layer. A polypoid lesion was predominantly composed of sarcomatous changes and was surrounded by moderately differentiated squamous cell carcinoma.View full abstractDownload PDF (9317K) -

JOURNAL FREE ACCESSA 68-year-old female was admitted complaining of general fatigue and lower edema of the extremities. Laboratory tests showed anemia and hypoalbuminemia. Endoscopic examination revealed a Borrmann type 2 gastric cancer on the lesser curvature from the lower corpus to the antrum. Abdominal CT scan and ultrasonographic examination revealed multiple liver metastasis. We considered this case to be an indication for endoscopic local injection of ethanol and Mitomycin C for gastric cancer and an implanta-ble access device catheter injection of FAM (Fluorouracil, Adriamycin, Mitomycin C) for the liver metastasis. The arterial intima was injured when the catheter was placed in the common hepatic artery. Therefore a catheter was placed in the splenic artery and drug was supplied from a side hole. The drug supplied from the left gastric artery to the gastric cancer passed through the right gastric artery and hepatic artery to the liver. We found necrosis of the gastric cancer and liver metastasis after 3 months therapy. This case was ambulatory and was followed up in the outpatient clinic for 12 months. We report good quality of life in a case treated by endoscopic local injection and an implantable access device catheter.View full abstractDownload PDF (7539K) -

JOURNAL FREE ACCESSIn one autopsy case, the structure of the fineblood vessels was examined clinicopath-ologically by injecting gelatin-added barium into the fundic varix. (1) The fundic varix was situated mainly in the mucosal substratum. (2) The inflow path, varix, and the outflow path were composed of a continuous blood vessel of an almost uniform diameter. There was no direct connection between the inflow and the outflow paths outside the gastric wall. (3) Many collecting venulae were observed in the area from lamina muscularis mucosae toward the surface, in lamina propria mucosae just above the fundic varix, and in the upper part of the stomach body. No direct connection was noticed between these collecting venulae and the fundic varix. These findings are beleived to be important in selecting an effective method of treatment for fundic varices hemorrhage.View full abstractDownload PDF (4372K) -

JOURNAL FREE ACCESSWe performed endoscopic ligation as a new hemostatic treatment for gastric bleeding using the technique of endoscopic variceal ligation (EVL) which was developed by Stigmann et al. The hemostatic treatment was employed in 2 cases of Dieulafoy's ulcer. As a result, permanent hemostasis was obtained by means of only one procedure in both cases. No rebleeding or perforation was observed. Although the indication is restricted within small gastric lesions whose fibrosis is none or mild, the hemostatic effect is considered to be as reliable as that of clipping hemostasis, and the homostatic procedure is rather easy except overtube placement. We suppose that endoscopic ligation using the EVL technique can be a new hemostatic treatment for gastric bleeding.View full abstractDownload PDF (4134K) -

JOURNAL FREE ACCESSPresened was a case of a 39-year old woman with a chief complaint of upper abdomi-nal pain. Because of recurrent ulcer of the angular region, she was referred to our department. Gastroscopic examination revealed irregular-sharped ulceration from the angulus to the lesser curvature of the lower body. From the histologic findings of biopsy specimens, we made a diagnosis of gastric plasmacytoma. Since no abnormal lesion was demonstrated on various studies including peripheral blood and bone marrow examinations, we performed total gastrectomy under the diagnosis of primary plasmacytoma. In the postoperative pathologic study, infiltration of tumor cells was confined to the sub-mucosal layer. The tumor was classified as IgM-λ on immuno staining of the specimen.View full abstractDownload PDF (13205K) -

JOURNAL FREE ACCESSTwo cases of sigmoid volvulus presenting megacolon were reported. Both cases were diagnosed as megacolon at surgical operation after successful endoscopic treatment for the sigmoid volvulus. Case 1 was a 55-year-old female with abdominal pain, a sense of fullness and constipation. Case 2 was a 62-year-old male with abdominal pain and constipation. Case 1 received an emergent operation because of recurrence after endoscopic treatment and Case 2 received a scheduled operation after detailed examinations. When megacolon was found, surgical operation should be selected even if the endoscopic treatment was successful.View full abstractDownload PDF (9020K) -

JOURNAL FREE ACCESSWe reported two cases of duodenal Brunnerioma which showed relatively rare symptomes such as of invagination and bleeding. Case 1 is 3G-year-old male admitted with severe epigastralgia and anemia. Stenosis at the retrobulbar portion and grape-bunch like tumor was found in the 2nd portion of the duodenum endoscopically. Severe pain seemed to be caused by invagination of the duodenum due to the huge duodenal tumor. Biopsy specimen showed normal duodenal mucosa with no abnormality. Malignant lymphoma of the duodenum was strongly suspected because abdominal CT examination suggested the rapid growth of duodenal tumor. Surgical operation was performed after chemotherapy. Resected specimen of the tumor revealed Brunnerioma. Case 2 is 39-year-old male admitted with complaint of melena. Duodenoscopy revealed a protruded lesion with ulceration covered with clotted blood in the 2nd portion of the duodenum. This polyp was removed endoscopically. Histology showed Brunnerioma with hypervascular structure. Invagination or bleeding induced by duodenal Brunnerioma is ralatively rare.View full abstractDownload PDF (10496K) -

JOURNAL FREE ACCESSA 55-year-old female visited our hospital because of epigastric pain. Ultrasonography showed a low echoic mass in the body to tail of the pancreas. Endoscopic retrograde pancreatography revealed a stricture of the main pancreatic duct without sidebranches in the lesion, we diagnosed it as pancreatic ductal cancer by these results. And then subtotal distal pancreatectomy was performed. Histological study showed this tumor consisted of spindle shaped cells with mitosis and they were positive for smooth muscle actin staining. The lesion was localized in the pancreas and diagnosed as pancreatic leiomyosarcoma. Primary pancreatic leiomyosarcoma is a very rare disease in Japan. There have been S (previous) cases reported in the literature.View full abstractDownload PDF (7808K) -

JOURNAL FREE ACCESSThere are many issues in diagnosis and therapy of primary rectal lymphoma. We reported the two cases with special reference to these problems. The first case was 48-year-old female which have a smooth-surfaced rectal tumor extended 5cm from the anal verge on digital examination. This tumor was diagnosed endoscopically as submucosal leision with malignancy and biopsy specimens showed suggestive of malignant lymphoma. Abdomino-perineal resection of the rectum and VEPA-chemotherapy after surgery were performed. This tumor was diagnosed histopathologically as malignant lymphoma, diffuse medium sized cell and B cell type. The second case was 78-year-old female which have a irregular-shaped rectal tumor extended 2cm from the anal verge by digital examination. This tumor was diagnosed endoscopically as rectal carcinoma (type I) but biopsy specimens showed no malignancy. This tumor was resected by transsacral approach and was diagnosed histopathologically as malignant lymphoma, diffuse medium sized cell and B cell type. Then, VEPA-chemotherapy was performed. Conclusively, we should observe endoscopically in detail for the preoperative diagnosis of rectal lymphoma and excessive surgery (abdomino-perineal resection) may be able to avoid on early stage-lesions by chemotherapy after surgery.View full abstractDownload PDF (11533K) -

JOURNAL FREE ACCESSWith the use of percutaneous transhepatic cholangioscopy, bilateral hepatic biliary drainage was successfully obtained via a single percutaneous tract with two Wallstents using the "stent through wire mesh technique" in two patients with hilar cholangiocarcinomas separating the right and left hepatic ducts. Strictures from the ipsilateral hepatic duct to the contralateral hepatic duct and the common bile duct were successfully negotiated via a single percutaneous tract with the use of cholangioscopy and guidewire techniques, and the strictures were fully dilated. The initial stent was placed across the first stricture. Subsequently, under cholangioscopic guidance a guidewire could be readily manipulated through the wire mesh of the initial stent into the second stricture. After dilation of the wire mesh with a high-pressure 10 mm balloon, the second Wallstent was introduced into the second stricture and and was deployed so that a part of the stent should overlap the initial scent. Finally, under cholangioscopic vision the wire mesh of the second stent, inside the first, was negotigated and dilated to obtain a lumen throughout the stents. Optimal positioning of the stents and adequate bilateral hepatic biliary drainage was obtained for both patients. Cholangioscopy seems to be a viable tool in reconstructing the bilateral hepatic ductal systems with Wallstents via single percutaneous approach.View full abstractDownload PDF (7917K) -

JOURNAL FREE ACCESSWe successfully implanted Strecker stent (Boston scientific Inc) covered with polyurethane membrane endoscopicaly in two mlignant biliary strictures. Jaundice has not been confirmed up to now after insertion of the covered Strecker stent. In one case cholangioscopy revealed that neither mucosal hyperplasia nor in crustation of bile was confirmed. We consider that Strecker stent covered with polyurethane could be an excellent device for endoscopic approach, because polyurethane is flexible and against in crustation of bile.View full abstractDownload PDF (7002K) -
