    Notes: Summary 1. The operative technique and the postoperative results of the original pylorus-preserving gastrectomy (PPG) and those of the Maki procedure as applied to cases of total gastrectomy are reported briefly. 2. The essence of these operations is to retain the pyloric cuff of 1.0–1.5 cm in length in order to preserve sphincteric function without the use of the drainage procedure. Ingested food was seen to empty gradually and rhythmically through the pyloric ring into the duodenum thereby avoiding dumping syndrome and reflux esophagitis. 3. As gastric acidity is reduced sufficiently by PPG, this method is to be recommended for treatment of intractable gastric ulcer cases and other benign lesions in which the foci are located in the distal half of the stomach. Though the method seems to be also useful in selected cases of duodenal ulcer, stenosis at the level of the pylorus and duodenum may preclude the application of the method. 4. The Maki procedure with jejunal interposition following nearly-total proximal gastrectomy is recommended in patients whose pylorus and its surroundings have remained free of tumor.

    Description / Table of Contents: Résumé Trente-trois spécimens de carcinome gastrique humain ont été transplantés chez la souris nue. La “prise” initiale de la tumeur a été obtenue dans 15/ 33 cas et 45.5% des tumeurs sont transplantables. La possibilité de transplantation est en rapport avec le type histologique, mais pas avec le stade clinique ni avec la classification de Borrmann. Les carcinomes différenciés (adénocarcinome tubulaire bien ou modérément différencié, adénocarcinome papillaire) se transplantent mieux que les tumeurs peu différenciées (adénocarcinome peu différencié, adénocarcinome mucineux). Le mode de croissance des tumeurs transplantées a été classé en 3 groupes: rapide, lent et stationnaire. Il n'y a pas de relation spécifique entre mode de croissance et type histologique. Tous les cancers, quel que soit le type histologique à l'exception des tumeurs de Krukenberg, ont pu être transplantés en série. Après transplantation en série, la croissance des tumeurs devient rapide. Pourtant l'aspect histologique de départ reste inchangé. Aucune invasion, aucune métastase n'ont été observées. L'injection intrapéritonéale de suspensions de cellules tumorales préparées à partir de transplants sous-cutanés d'adénocarcinomes peu différenciés de type Borrmann III donne une croissance avec production d'ascite, invasion régionale et métastases. L'ascite s'accumule en 3–6 semaines aprés l'innoculation. L'injection intraveineuse de liquide d'ascite chez la souris nue provoque le développement de métastases. L'histologie de la tumeur souscutanée est comparable aux aspects de la tumeur originale prélevée chez le malade.
    Notes: Abstract A total of 33 specimens of human gastric carcinoma were used for transplantation into nude mice. Initial tumor “take” was accomplished in 15 of the 33 tumors, and the transportability rate was 45.5%. Transplantability correlated with histologic type, but not with clinical stage or Borrmann's classification. The transplantability rate of differentiated carcinomas, such as well-differentiated tubular adenocarcinoma, moderately differentiated tubular adenocarcinoma, and papillary adenocarcinoma was greater than that of poorly differentiated tumors, such as poorly differentiated adenocarcinoma and mucinous adenocarcinoma. The growth patterns of transplanted tumors were divided into 3 types: rapid, slow, and persistent. There were no specific relationships between growth pattern and histologic type. All histologic types, except signet ring cell carcinoma, could be transplanted serially. Tumor growth became rapid after serial transfer. However, the original histology of these tumors was unchanged. No invasion or metastases were encountered. Intraperitoneal injection of a tumor cell suspension, prepared from subcutaneous transplants of a poorly differentiated adenocarcinoma of Borrmann type III, grew in an ascites form, with invasion and metastasis. Ascitic fluid accumulated within 3–6 weeks after injection. Subsequently, intravenous injection of ascites fluid produced metastases in nude mice. The histology of the subcutaneous tumor was similar to that of the original tumor from the patient.

    Notes: Abstract An 81-year-old female was admitted to hospital with anemia and abdominal discomfort, however, various pre-operative diagnostic workups for the gastro-intestinal tract revealed no significant change. At the time of surgery, a small intestinal tumor was discovered by means of endoscopy and seven centimeters of ileum was radically resected. The tumor was subsequently diagnosed histopathologically as hemangioendothelioma. The patient recovered quickly and now, 6 years later, has had no sign of tumor recurrence. The incidence of this tumor is reportedly less than 3 per cent of all tumors found in the small intestine and the prognosis of this tumor in the small intestine is poor. A five-year-survival rate can be referred to only 33.3 per cent of the reported cases.

    Notes: Abstract A case of a hernia traversing the lesser sac with a primary defect in the greater omentum and a secondary defect in the lesser omentum is reported herein. This type of internal hernia is extremely rare and we have found only three other reported cases apart from our case. All four cases in whom this type of hernia occurred were young people. The general manifestation resembles acute intestinal obstruction and a plain radiograph shows obstruction of the upper small intestine. An erect lateral view of the abdomen often shows the anatomical location more clearly. Bowel resection was performed in two cases and all of the four reported cases recovered uneventfully.

    Notes: Summary S. Ebashi (National Institute for Physiological Science) summarized the conference from the Japanese point of view. He emphasized the opportunities for fruitful cooperation between basic and clinical scientists of both the United States and Japan. C.F. Code (La Jolla, California), speaking for the United States and third country groups, pointed out the tremendous growth in the field, as evidenced by the quantity of new data and the quality and uniqueness of the experiments. He stressed that continuing efforts are needed to ensure US-Japan communication and cooperation in the future, efforts made easier by seminars such as this.
