    Endoscopic electrocoagulation was performed in combination with a large-dose adminis-tration of antiulcer-agents and/or hemostatics through a stomach tube in fifteen cases of bleeding gastritis, twenty-one cases of bleeding gastric ulcer, nine cases of duodenal ulcer, three cases of gastric cancer and four cases of Mallory-Weiss syndrome. Results were successful in all cases. Aspects of bleeding gastric ulcer experienced were divided into six types from the find-ings at urgent endoscopic examinations. Those are; type I; an ulcer with projectile bleeding, type II ; an ulcer with oozy bleeding. type III; an ulcer with a marked erosion in the vicinity, type IV; an ulcer with an exposed blood vessel at the bottom, type V; an ulcer coated with coagulated blood. type VI; an ulcer covered with a yellow fur.Endoscopic electro-coagulation is principally indicated for the types I and II, for the other types may be treated successfully with a large dose of antiulcer-agents and/or hemostatics via a stomach tube. Indications for surgery should be determined not only by its present state of hemorrhage, but also by a history and location of the ulcer, for an ulcer in the upper part of gastricbody may, in our experiences, be cured by conservative treatments including endos-copic coagulation, even when the ulcer shows a projectile hemorrhage.

    As the preliminary study of laser photocoagulation of hemorrhagic gastric ulcer, the size of exposed blood vessel in the ulcer was examined. The subjects were 78 lesions seen in 71 patients. The mean diameter of exposed blood vessel was 0.92mm. The vessels coresponding to 70.5 % in the lesions were smaller than 1mm and 94.9 % of them were smaller than 2mm. This means that the ruptured blood vessel seen in the ulcer will become the object of photocoagulation by Nd-YAG. Furthermore, by the studies of those ulcers, they mainly located on the lesser curvature of lower body and angulus, where it was difficult to find out by the forward viewing endoscope.

    Intestinal metaplasia of the stomach under the age of 30 was studied endoscopically by vita staining of direct dye scattering method (0.5% methylene blue). The biopsy specimens were investigated under dissecting microscopic observation by double staining of LAP Leucine aminopeptidase) and AL-P (Alkaline phosphatase) according to the method of of 114 patients Nakahara. Following results were obtained; 1) Intestinal mataplasia was present in 8 of 36 patients (22%) of Second decade and 39 (34%) of third decade. 2) In 2 of 4 patients under the age of 30 followed up by endoscopy scanty methylene blue stained areas were seen in regenerating mucosa of gastric erosion, which were confirmed by histochemical investigation. The early stage of intestinal metaplasia of the gastric mucosa was seen in regenerating mucosa of eroded verrucous lesions or multiple erosions, and f ilamentous patterns were demonserated by using Olympus GIF-D3 with 8 magnification. 3) In cases without erosion in the stomach we experienced linear and ramified types of intestinalized mucosa at the initial stage.

    The authors measured disaccharidase (maltase, sucrase and lactase) activity of gastric cancer (focus), intestinal metaplasia surrounding focus and intestinal metaplasia, 1.5cm-2.0cm distant from the focus by gaschromatography, and immunohistochemically studied by a-f etoprotein (AFP) labeled with FITC. 1) No difference of disaccharidase activities were shown in any part of early cancer and advanced cancer. 2) Disaccharidase activities were higher in well differentiated cancer than poorly dif-ferentiated cancer. 3) As the distance from the focus was bigger, disaccharidase activities became higher, and those of intestinal metaplasia in the stomach without gastric cancer showed the highest values. 4) Immunohistochaemical localization of AFP in gastric cancer was recognized in 10 of 20 cases. (50%) 5) According to each type, AFP was often recognized in papillary adeno-carcinoma (50%) and signet ring cell carcinoma (80%). But it was a few in poorly differentiated adeno-carcinoma (25%) and well differentiated adeno-carcinoma (33.3 %). 6) In gastric cancer, localization of AFP was recognized at cytoplasm, cell membrane and basal membrane. 7) In intestinal metaplasia surrounding gastric cancer with AFP, localization of AFP was recognized in 4 of 10 cases (40%). But in that without AFP, it was not recognized.

    In our clinic, 7 cases of primary duodenal cancer except cancer of the duodenal papilla were experienced. We have examined X-ray and endoscopic findings and clinical courses of these cases. These lesions, located in the duodenal bulb, the second and the third portions of the duodenum showed some characteristic findings, in each location in our study. On X-ray examination, cancer of the bulb and the second portion was shown as a polypoid lesion, but cancer of the third portion was shown to be an ulcertive lesion such as Borrmann II type of gastric cancer. On the other hand, endoscopy was performed in all cases, but 2 cases at the third portion were not seen, because of being unable to approach to the lesions. On endoscopic findings, cancer of the bulb and the second portion appeared to be a polypoid lesion like II a or Borrmann I type of gastric cancer. We guess that duodenal cancer might progress and change from polypoid to ulcerative lesion. Finally, we must refer to a miserable prognosis of these cases, because these patients were seen at late stage of cancer after suffering for too long period.

    Utility and limitation of the laparoscopic examination aimed at the diagnosis of hepatic cancer which is one of the localized liver diseases are studied. The subjects were 13 patients of whom hepatectomy and autopsy were performed after laparoscopy, and other laboratory and X-ray examination were also performed. In 6 cases, malignant tumor on liver surface was seen under direct vision through laparoscope. While, malignant tumor was not appeared in 2 cases laparoscopically, although hepatic cancer was diagnosed by other examinations. In 3 cases, liver maligancy was failed to be diagnosed by both of the examination of laparoscope and other evaluations, however, hepatic cancer grew up after 6 or 12 months later. Last 2 cases was liver cirrhosis. The area of liver surface which was able to see under laparoscope was measured retrospectively in comparison with removed livers by operation and autopsy. Visualized areas by laparoscopy in these cases were about 24 percent of the entire liver surface in right lobe and 62 percent of that in left lobe. In this study, 6 cases out of 8 patients with hepatic cancer were diagnosed by laparos-cope. Furthermore, visualizing limitation on the liver surface while laparoscopy using present apparatus was clarified.

    Nine cases of piecemeal polypectomy were encountered in our 370 polypectomy series. Four were intentional and five were consequential cases. Most polyps were over 2cm in diameter and sessile or semipedunculated in shape. There were 6 early earcinomas with 2 invasive and 4 focal carcinoma. In 3 examples piecemeal polypectomy was failed and additional surgical excision was required. In one instance bowel wall was found to be completely destructed and replaced by fibrous tissue suggesting hazardous aspect of this technique. However, in 6 cases piecemeal polypectomy was useful as a treatment of large polyps avoiding laparotomy, particularly in elderly patients. It should be born in mind that piecemeal polypectomy would give us ill-orientated specimens for histological examination although early carcinoma would be frequently encountered. Indication for piecemeal polypectomy should be determined carefully in each patients on the basis of its merit and demerit.

    In April 1978, a 72 year-old woman visited the Kokura Memorial Hospital complaining of a discomfort in the anterior chest after meal. Physical examination revealed no abnormalities. Roentogen examination of the upper gastrointestinal tract showed an irregular, well-defined elevated lesion in the duodenal bulb. Duodenof iberscopy revealed a nodular polypoid lesion on the posterior wall of the duodenal bulb. The surface of the lesion was not associated with any redness, bleeding, erosion or ulcer. Histological examination of the biopsy specimen showed adenocarcinoma. Surgical operation disclosed a nodular tumor with a short stalk, measuring 1.0 × 1.0cm in diameter, on the posterior wall of the duodenal bulb distal to the pyloric ring by about 2cm. Histology of the resected specimen revealed well-differentiated tubular adenocarcinoma limited within the mucosa with no lymphnode metastasis. Case reports of a primary early carcinoma of the doudenum are rare. Seven cases have been described in Japan, except for those in the papilla Vateri. Of the seven cases reported, four were in the duodenal bulb, two were suprapapillary and one was inf rapapillary. Our case appears to be the eighth case reported in Japan.

    This report is a case of agenesis of the dorsal pancreas, which has been reported in four cases in Japan and also rarely seen in foreign countries. a 46 year old man presented with hungry pain, anorexia and weight loss for two months. He visited a doctor. 75Se-Pancreas scintigraphy showed the deficit of the portion of pancreatic body and tail. ERP showed the obstruction of the main pancreatic duct looked like the short main pancreatic duct symdcome. He was operated with the suspicion of pancreatic cancer. The diag nosis on operation was the agenesis of the dorsal pancreas. Histologically the remaining pancreas was almost normal, but islet cells were increasing in number, than that in normal pancreas head.
