The Authors report four cases of primary gastric lymphomas. They stress the anatomopathological, clinical and therapeutic problems related to this disease because, at present, they are still discussed.
The Authors, after pointing out how incidence of gastric cancer has been reducing last decades, dwell upon environmental and genetic factors that may be linked to the occurrence of such neoplasia. After reporting the data of a retrospective study, they consider the survival rates related to the clinical stage and site of the tumor as well as the therapeutic treatment adopted. They conclude that, even though today gastric cancer is a neoplasia with a still unfavourable prognosis, an early diagnosis and a proper therapeutic procedure may give sufficient guarantees of success.

The authors, after emphasizing the value presently ascribed to the conception of "epithelial displasia" as initial histologic and cytologic alteration, common to all groups of patients with high risk of development of colorectal cancer, review the mani precancer lesions of large intestine. As a conclusion, they affirm the main target one presently aims at for the screening in groups with high risk is to precociously identify the stage of transformation of epithelial displasia into carcinoma, so as to be able to set up a timely treatment.

The Authors, after pointing out that, in geriatric age, the incidence of left colon carcinoma has significantly increased, and this, in a high quantity of cases, goes unnoticed in precocious stage, but appears "d'emblée" pith an occlusive situation, state their experience concerning the surgical treatment of occlusions due to left colon carcinoma in patients aged over sixty. From the evaluation of the results they obtained, the Authors assert that, if the operation is performed after a correct appraisal of the patient's general conditions and after an adequate counterbalancing of the metabolic and functional alterations, often present in old people, the operative mortality, the postoperative complications and the indices of survival are not so significantly different from those remarked in the young subjects.
The Authors, after pointing out the incidence of complications subsequent to lymphoadenectomy performed with the traditional means (lymphorrhea, dehiscence of the pound, etc.), report their experience concerning the removal of inguinal or aqillary lymphnodes of patients suffering from cutaneous malignant melanoma (N+), performed pith laser lancet. After a short description of the peculiar features of the Laser Surgical Unit they used, the Authors emphasize that, thanks to the peculiar power for the laser lancet to close the lymphatic vessels during the lancing itself, surgeons can prevent the postoperative lymphorrhea, which is the main cause of dehiscence of such surgical wounds.

An experimental study was conducted on the use of a new iodate-molecule, B 10610, synthesized in the Bracco research Laboratory, for intra-operative cholangiographic diagnostics. For the purpose of evaluating the possible rise and the extent of any pancreatic damage in animals subjected to intra-operative radiological exploration of the biliary ducts with the use of the said substance, the blood levels of amylase and plasmatic 1st deoxyribonuclease were assayed after various time intervals, such tests being particularly specific in the humoral diagnostics of both acute and chronic pancreatic diseases. On the basis of the tests made, it is concluded that the introduction of this new dye does not cause irreversible lesions of the pancreas, but only purely functional and transient alterations.

Experimental research was carried out for the purpose of studying the behaviour of the vasa-vasorum in a group of animals in which, by means of a Weavenit prosthesis, the section of aorta lying between the branches of the renal arteries and the trifurcation of the terminal oartic section had been substituted. From the results of the research the Authors conclude by asserting that above all the technique they used allowed excellent visualisation of the vasa-vasorum, as shown both by the histological preparation coloured with haematoxylin-eosin and by the preparations carried out under the stereomicroscope. Furthermore, in the microscopic observations there is the indisputable presence of vessels of varying calibre which, from the neo-adventitia through the meshes of the prosthesis, are carried to the level of the neointima, confirming that the vasa-vasorum constitute the most important reactive phenomenon for purposes of vascularisation of the prosthesis.
Authors, considering the increasing of the middle duration of life and the increasing of geriatric population, examine various surgical problems in the elderly. They took in consideration not only the age, but all the other markers of surgical risk related to the surgical illness, to the associate illness and to the type of operation. After reporting their experience in the treatment of geriatric patients, they conclude that a scrupulous surgical preparation, a correct indication to the operation and an accurate overseeing after surgery are necessary to do that the elderly patient faces surgical intervention with the same capability of success of the young.
