The author reviews sorne general aspects· of lipomas and invagination of small intestine in adults, such as national case material, patbology, clínica! and radiologicalaspects, therapy employed and surgical management. He also presents bis own case material consisting of four patients _with pedicled lipoma of small intestinecomplicated by ileo-ileal and ileo-colic invagination. In one case there was low ileal occlusion, with vascular involvement and mesentero-ileal necrosis. In the remainingthree there was jejunal, ileal and ileo-colic invagination. In cases of urgency due to this complication he advises exploratory laparotomy for diagnostica! purposes.The lesion found and its topography will determine surgical procedure employed. When the ileocaecal sector is involved and it is not possible to deinvaginateit, or else there is devitalization, a right ileo-colectomy is indicated. 'I'his will also be the tactic employed when carcinomas cannot be totally discarded.The only safe means, in bis opinion, of establishing the real nature of tumor is through histopathological study, since tumors of similar symptomatology, clinical aspect and topography may or may not be malign. 

A patient had a carcinoid jejunal tumor, diagnosed with the aid or pathological anatomy, and considerable mesenteris metastasis displacer towards the large vessels.Oleohepatography and arteriography showed hepatic metastasis, but not gammagram, Mesenteric vessels had aJtered and superior mesenteric arteriography indicated discreet initial dilatation, reduced calibre and terminal stenosis; there was reducton of blood flow towards periphery. Si1ce worldwide experience on the subject is limited we believe that this contribution is of value with respect to vascular pathology of this tumor.

Malrotation is reported as responsa ble of a high number of cases of duodeno-yeyunal obstruction. Analysis is made of obstructive mechanisms: a) volvulus of medium intestine, favourished by the precarious fixation of the mesentery; b) Ladd's band. Embriology of ombilical anse and its abnormal positions are remembered. Clinical feature are described, emphasazing vomiting as majar symptom as well as its characteristics:time of appearence, its containsts, evolution and consequences. Diagnostic is also considered, based on clinical features and Jaboratory tests, specially radiology. Treatment is studied, refering the most employed surgical .actics as wel! as pre and postoperative management.Results are considered with analysis of causes of death.

Complications, their causes and death rate, in two groups of burned patients, are analyzed. One group was treated with Calciparine, the other served as witness. -This treatment is based on former experimental work. -The treatment is simple and inocuous. -Finally, the conclusion is that the group subject to this treatment had a better evolution.

Atresia and estenosis of the jejunum and ileum are the most common causes of intestinal occlusion in the newborn. Different types are described. Most significant symptoms are repeated bilious vomiting, followed -or not- by absence of meconioum and flatulence, and by abdominal distention. Radiology comprises plain radiography and contrasted study of the colon. Treatment is always chirurgical. Technics andtactics are considered, as well as the treatment of related malformations. Emphasis is placed on the post-operatory of the massive intestinal resections. Mostality oscillates between 30 and 50 % , being higher when the atrasia is lowest.

A patient had carried for five years as introduodenal gauze roll which he had tollerated until recently when he began to suffer from digestive problems which ledto exploratory surgery. The foreign body was extracted by enterotomy. Since no similar case was found in the bibliography consulted, we consider its presentation justified.

A study of anorectal atresia as possible cause of intestinal obstruction in the newborn is presented. Its incidence and embryology are studied as well as the clinical picture of all its forms. s empJ-¡.asized the fact that intestinal obstruction i5 not present when there is sorne communication tothe exterior due to the presence of vaginal or perineal fistulae. Radiology is most important in order to demonstratethe }YPe of the anomaly and helps planning its treatment. Operati\¡'e indication and different surgical approaches are. studied, depending on the experience obtaine in our country.

The author presents a case. of a foreign body (compress) tollerated for firteen years and enclosed in the liver.

During the last 2 years, the surgeons· of the S. S. Army Hospital have operated 31 patients with vascular gun wounds.This paper offers an analysis on the balistic data, in order to explain sone arterial lesions. The importance of the temporary cavity made bythe circumference of ali the thact sorrounding ali the way of the bullet through the tissues, which are radiallymoved son indirectally damaging vessels that never were. in contact with the bullet. The types of these wounds are enumerated. The isolated arterial spams, froftently coexisting with intima! injuries, even very small, favorable to secondary thrombosis, is noted for its infrequency.The paper insists on emergency surgery in beating haematomes and traumatic arterio-venous fistulae. Diagnosis and treatment of arterial injuries are systematized by the clinic and contrast radiologic study.

Peripheral arterial aneurysms are caused by the following reasons: arteriosclerosis ( 80 % of cases); infections (micosis); and post-dilatation. With increase of arterial repair surgery, false aneurysms are ofte?l observed; these are termed anastomotic aneurysms.Peripheral aneurysms often have complications which imply a serious threat to the circulation of the limb, very often leading to gangrene and even death of patient. There is unanimous agreement that surgery of peripheral aneurysms should be performed at an earlystage and that treatment will consist of abscission of aneurysm and re-establishment of arterial continuity, In arder to prevent formation of anastomotic aneurysms, it is important to perform termino-lateral anastomosis in the inguino-crural region, avoiding excessivetension and employing synthetic suture material. The use of anticoagulant s in the immediate post-operatory period seems to be an important factor in development of these aneurysms. However, there is no doubt that advanced degenerative arteriosclerotic lesions in the re<teiving artery play an extremely important part in production of anastomotic aneurysms.
