JOURNAL FREE ACCESSThe present study referred to histopathological investigations of gastric mucosal atrophic extension. The degree of mucosal atrophic changes seen in chronic gastritis was tentatively called "atrophic sloping". In order to determine the atrophic border, endoscopic Congo Red method was applied prior to stepwise biopsy method (11 biopsy specimen) of gastric mucosa. As results, gland atrophy was severe in the antral region, and the closer to the oral side the milder gland atrophy was without any relationship with the extension of atrophic zone. The cell infiltration was highly observed at the site of atrophic border. Moreover, as compared with the greater curvature, in the lesser curvature gland atrophy, cell infiltration and intestinal metaplasia were maximum in their grades. In order to make sure "atrophic sloping" not only by biopsy specimen, but also by resected spcimen, in another ward, for better understanding the atrophic changes in the whole portion from the fornix to the antrum, the entire lesser curvature was examined histologically using resected stomach, in application of Swiss-roll method. In conclusion, gland atrophy, cell infiltration and erosion was the most severe according to the atrophic border. The gland atrophy, cell infiltration and erosion were the highest on the atrophic border. On the other hand, the histopathological study on the Fundic-Cardiac border demonstrated similar atrophy comparing to the surrounding mucosa. As the consequence, regarding to the etiology of gastric atrophy, erosion and the f ollowingly cell infiltration must occur in the beginning, and finally the gland atrophy may happen through the course of glandular restoration or regenerationView full abstractDownload PDF (6978K) -

JOURNAL FREE ACCESSFrom the morphological and enzymological investigation, the wide variation were observed in intestinal metaplasia and classified into complete and incomplete types according to its nature. To clarify the variation of the intestinal metaplasia, I investigate the proliferation kinetics of intestinal metaplasia by means of the autoradiography by 3H-thymidine and the measurement of the nuclear DNA-content by cytophotometry. From these observations, in complete intestinal metaplasia (ALP +, LAP +), the generative cell zone is located at the lower % portion of the gland. On the other hand, in incomplete intestinal metaplasia (ALP-, LAP +), the generative cell zone is enlarged. The measurement of the content of the nuclear DNA content revealed that there was few aneuploid cells in gastric intestinal metaplasia and incomplete intestinal metaplasia shows a small peak at the 4c point. I made clear that there is the difference in the rate of cell turnover between incomplete and complete type intestinal metaplasia and this evidence may be the key point to solve their nature.View full abstractDownload PDF (4653K) -

JOURNAL FREE ACCESSTo clarify the nature of the intestinal metaplasia, I investigated the absorbent function on the point of the morphology of the microvilli and the oleic acid load in vivo and in vitro. Electromicroscopic findings revealed the variations of the microvilli. From the bottom of the gland to the surface, the microvilli maturates in morphology. In incomplete intestinal metaplasia, immature microvilli is observed in wide portion. On the other hand, in complete intestinal metaplasia, immature microvilli is located at the base of the gland and mature microvilli spread from the surface. The oleic acid load in vivo and in vitro revealed the difference of the capacity of complete and incomplete type of intestinal metaplasia.View full abstractDownload PDF (9986K) -

JOURNAL FREE ACCESSAcute gastritis is often encountered in daily clinical practice. The onset of sudden epigastric pain, nausea and vomiting is the most common symptoms, and for an accurate diagnosis, upper GI series and/or endoscopy ase usually required. The similarities in the X-ray findings of acute gastritis to those of gastric carcinoma are well known, however, there is a paucity in the literature of endoscopic classification in patients with acute gastritis of the corpus. Detailed studies are made of endoscopic finding in 42 patients with acute gastritis of the corpus. We clincally classified these patients into three types; Type A; Reddish type, Type B; Erosive type with hemorrhage, Type C; White coat type with erosions, based on endoscopic findings. Type A is the mildest and seems to be cured without treatment.View full abstractDownload PDF (4558K) -

JOURNAL FREE ACCESSEndoscopic study on background mucosa of gastric xanthoma was carried out in 51 cases. For evaluating a relationship between glandular border and location of gastric xanthoma, endoscopic Congo-red Test was performed in 31 cases. No relationship between glandular border and location was proved, and the majority were found in the pyloric gland area. However, 4 cases were situated in darkly colored area by Congo-red Test, which was proved to be fundic mucosa by biopsy and 5 were located in the intermediate zone. Simultaneous study of atrophic grade shows slight to moderate atrophy in the majority. No significant difference was shown in severity of atrophy between the mucosa of 2 cm oral and anal side of xanthoma surface. With Methylene Blue Dyeing Method, xanthoma surface stained positively in only one of 14. The adjacent area did not stain, but the mucosa over 2cm away from xanthoma tended to stain positively in the majority. Biopsy specimens obtained simultaneously demonstrated similar tendency ; intestinal metaplasia on xanthoma surface was negative in 51.6%, when it exists, it was slight (38.7&) and the surrounding mucosa showed intestinal metaplasia more frequently than xanthoma surface. Although, the present study showed gastric atrophy to be a related factor of xanthoma pathogenesis, the possibility of existance of gastric xanthoma without accompanyng gastric mucosal atrophy was suggested. At the same thme, the role of intestinal metaplasia in xanthoma was not clarified in the present, and more detailed investigation will be required in the future for explaining the relationship with intestinal metaplasia.View full abstractDownload PDF (4286K) -

JOURNAL FREE ACCESSThe Malltry-Weiss syndrome has been said to be one of the important cause of the upper gastrointestinal bleeding. We experienced 11 cases of this syndrome diagnosed by the emergency endoscopy from October 1975 to April 1981. The incidence was 9.8% of upper gastrointestinal bleeding in our series. The figure was much higher than the rate which had been thought. As the result, the emergency endoscopy was thought to be useful for the diagnosis and selection of treatment of the Mallory-Weiss syndrome. Nine cases were treated nonsurgically, and 2 cases were treated operatively.View full abstractDownload PDF (2010K) -

JOURNAL FREE ACCESSThe experimental chronic pancreatitis model was successfully made by using the contact freezing method. By using this model, we studied the correlation between the histological findings and pancreatogram, especially about the adjacent fibrosis and stricture of the main pancreatic duct. The results were as follows; 1) Fibrosis was shown surrounding the main pancreatic duct at the contact freezing point. 2) Histologic section of the main pancreatic duct was deformed by the its surrounding fibrosis. 3) The inner diameter of the main pancreatic duct at the freezing point was decreased in the case with periductal fibrosis. 4) The distal main pancreatic duct was dilatated and the surrounding tissue was histologically alterated. According to these results, we had the opinion that the deformation and stricture of the main pancreatic duct due to adjacent fibrosis were the manifestation of early stage of the chronic pancreatitis.View full abstractDownload PDF (3231K) -

JOURNAL FREE ACCESSHyperplastic nodule has been focused as a precancerous lesion of hepatocellular carcinoma (hepatoma) during experimental hepatocarcinogenesis. However, it is well known that all of them do not grow up to hepatoma, but several nodules are related to developing hepatoma. Therefore, we examined laparoscopically the liver surface of rats continuously fed with 0.03% 2-acetylaminofluorene. The laparoscope used in this study was a newly designed small caliber laparoscope for experimental animals, developed by MACHIDA Co.. It was the rigid type, 5 mm in diameter, 250 mm in length, with front view. At the 13th week after the experiment started, red hyperplastic nodules were recognized among the many hyperplastic nodules. At the 27th week, a part of liver surface where the red hyperplastic nodule was previously recognized, was raised. At the 33th week, the site of liver surface, where hapatoma grow up, was nearly corresponded with the site of red hyperplastic nodule previously recognized. From these findings, it is concluded that these red hyperplastic nodules seem to be related to the development of hepatoma.View full abstractDownload PDF (7017K) -

JOURNAL FREE ACCESSLaparoscopic findings of five cases of hepatic amyloidosis and its diagnostic signifi-cance were reported. The histological study of one of those cases demonstrated massive amyloid deposition in both the sinusoidal wall and the portal area. In the section of the liver biopsy of the other four cases, however, amyloid deposition was limited to portal area. The laparoscopy of the former case revealed diffuse reddish-purple, course granular liver with extensive dilatation of surface vessels and lymphatics, while on the liver of the latter cases, there were many fibrous adhesions between the liver and the peritoneum, and white fibrous band surrounding the central reddish-purple area was observed. The liver biopsy of these five cases was performed safely under laparoscopy. There is no specific diagnostic procedure except for laparoscopy, and we occasionnally had difficult cases to make a diagnosis of amyloidosis with histological examination of the liver biopsy with routine staining method. The laparoscopic findings of hepatic amyloidosis were characteristic, and liver biopsy could be performed safely under laparoscopy. Thus, laparoscopy was thought to be a significant and beneficial method for a diagnosis of hepatic amyloidosis.View full abstractDownload PDF (7639K) -

JOURNAL FREE ACCESSTere were 369 colorectal polyps polypectomized endoscopically during past eight years in Toranomon Hospital, in which 15 polyps of juvenile type were found among 14 patients. The age ranged from 3 to 55 years, 13 patients being over 20 years old. Seventy-seven percent of the patients were male. Seventy-three percent of the polyps were located within the rectum and sigmoid colon. Most Qf these polyps seemed pedunculated in macroscopic appearance, showing smooth and reddish surface with erosions and bleeding. Magnifying photograph of removed specimens showed that structure of pits of juvenile polyps could be hardly visualized. And this is compatible with the fact that the outer surface is often ulcerated. Review of the histology in 15 juvenile polyps revealed metaplastic tubules in nine (60 %) and adenomatous foci in two (13%).View full abstractDownload PDF (4282K) -

JOURNAL FREE ACCESSWe reported our clinical experiences with the improved prototypes of ultrasonic gastroscope II and ultrasonic laparoscope II. The main points of the improvement in the present prototype are as follows. The visual direction is changed from the previous side view to the end view. The distal rigid part is shortend from 59 mm down to 45 mm, and the part of ultrasonic probe becomes 90 degree flexible bilaterally. With these mechanical improvements, the present ultrasonic scopes were evaluated to be very efficient in the clinical use, and some clinical cases were presented herein in which the present ultrasonic endoscopy was regarded as very useful for establishing the diangosis. Especially, the present procedure was proved to be very diagnostic for a mass lesion in the esophagus.View full abstractDownload PDF (6428K) -

JOURNAL FREE ACCESSEndoscopy and radiography are complementary rather than competitive procedures in the diagnosis of the large intestine, and diagnostic accuracy will be greatly enhanced by their combined use. Colonic diseases such as cancer or polyp occur most frequently in the rectum and sigmoid colon and barium enema sometimes fails to demonstrate a lesion. Therefore, fiberoptic sigmoidoscopy in combination with barium enema seems to be valuable. Two procedures on different days may cause diagnostic discrepancies and two bowel preparations will give much trouble to the patient. We, therefore, attempted to have both barium enema and fiberoptic sigmoidoscopy in 46 patients on the same day. The barium enema showed satisfactory visualization and no adverse effects of preceding fiberoptic sigmoidoscopy on barium enema were noted. It is concluded that from a practical point of view, the combined use of fiberoptic sigmoidocopy and barium enema on the same day is very useful. There are many advantages in this method as the followings : 1) Diagnostic accuracy can be raised in the lesions of the rectum and sigmoid colon. 2) This method can save time and trouble for the patient. 3) This method can eliminate diagnostic discrepancies caused by the two diagnostic methods done on different days. 4) This method may give significant diagnostic information to a clinician earlier.View full abstractDownload PDF (657K) -

JOURNAL FREE ACCESSIt is very rate that calcium deposit occurs in gastric cancer and also the calcification is detected by simple X-ray examination. We have experienced such a case. In our case, spotted calcification was detected in an abdominal plain film and postoperative studies confirmed that this calcification was calcium deposits within the gastric cancer. Here, we report this case, collect similar cases reported already in Japan and literally refer to their characteristics. As a result, histology of the gastric cancer with calcium deposit was exclusively mucinous adenocarcinoma in the literature and the mode of calcification seen in X-ray examination was characteristic.View full abstractDownload PDF (6750K) -

JOURNAL FREE ACCESSA 74-year-old man complaining of hematemesis under-went an emergency endoscopy soon after admission. No abnormal findings were noted in the esophagus and stomach. But, malignant ulceration (Borrmann type 2 ) was observed in the postbulber portion, which extended down to the papilla of Vater. Histological diagnosis by biospy was anaplastic carcinoma. Hepatic and pancreatic scintigrams showed no abnormal findings. Celiac angiogram failed to reveal any abnormalities in the pancreas and gallbladder. From these findings a diagnosis of primary duodenal carcinoma was made. However, laparotomy revealed carcinoma the gallbladder infiltrating to the duodenum. Although the gallbladder cancer easily invades the duodenuum, the reports of duodenal ulceration are extremely rare, especially of those cases which are diagnosed endoscopically. The precise information in this case would be helpful to differentiate from duodenal carcinoma.View full abstractDownload PDF (5076K) -

JOURNAL FREE ACCESSTwo cases of mucocele of the appendix were observed. The first case, 48-year-old male, complainted of epigastrial distress with two months duration. The second case, 77-year-old female, admitted on emergency for severe upper abdominal pain on sudden onset. Barium enema studies showed tumor shadow compressed cecum and terminal ileum in case 1, and submucosal tumor like shadow in case 2, which indicated invagination. No appendix was identfied in both cases. Colonoscopy in case 2 revealed a mass at a cecum, which was yellow-orange, broad-based, covered by normal mucosa, and very soft when poked with the biopsy forceps. Preoperative dignosis was a extra-intestinal tumor at ileo-cecal region in case 1, and mucocle of the appendix or lipoma in case 2. At operation, no free mucus or ascitis was found, and the tumor was the swollen appendix in both cases. The sizes were 8.0 × 3.6 cm in case 1, and 4.0 × 2.5 cm in case 2. When appendix was opened, it was found to contain clear thick substance. Microscopic examination showed that the epithlium was mostly absent, but partially flattened cuboidal cells were noted. No intramural tracking of the mucus into the appendicceal wall was seen. Postoperative courses were uneventful in both cases. The literatures of mucocele of the appendix were reviewed.View full abstractDownload PDF (6607K) -

JOURNAL FREE ACCESSJaundice caused by extra hepatic biliary obstruction can improved by percutaneus transhepatic biliary drainage (PTCD). In patients with carcinoma of the pancreas or biliary duct, PTCD is helpful ajunct in preparation for elective surgical procedure. In inoperable cancers of the hepato-biliary system, endoscopic biliary drainage using ERCP and endoscopic sphinctoro papillotomy (EPT) has been tried with success. Recently, we have succeeded in establishing internal biliary drainage by preliminary percutaneus transhepatic cholangio drainage (PTCD) followed by insertion of a permanent drainage tube through ERCP method ; this catheter can be placed proximal to the site of obstruction and the distal end of the tube remains in the duodenum. Endoscopic papillotomy is necessary before the permanent tube is inserted through the common bile duct channel. We believe this to be the only noninvasive approach available, in the management of advanced carcinoma of the biliary tree.View full abstractDownload PDF (7208K) -
