Clínica! research on central venous catheterization and ensuing complications, the reasons for this research, its goals, the material and methods employed, aredescribed by the authors. Results obtained are analyzed and discussed. Special stress is laid on the importance of radiological control, due to the frequency ( 30 % )with which the catheter takes an anomalous position. 'I'he paper includes the conclusions arrived at.

Post-mortem and experimental research work aimed at demostrating the topography of the different anatomical elements which condition a satisfactory phrenotomy,is reported by the author. The intradiaphragmatic distribution of the phrenic nerve and its cascular connections are analyzed. Theauthor differentiated between elective phrenotomies and politraumatized patients. The value of diaphragmatic wounds as approach for exploratory purposes is discussed and limitations thereto are established

For the first time in national case material, or so we believe, there is a case of diffuse, papilar, malign  mesothelioma in the omentum majus infiltrated in colon,stomach, splenic and pancreatic capsule and liver. It was slighlty round. For this reason the author reviews pathology, diagnosis and treatment of this raredisease.

The authors have treated 6 cases of sigmoid volvulus. In this paper they analyze those elements of assistance in the formulating of a better clinical-radiological diagnosis and they asses usual features such as advanced age, frequency of serious lesiona! association, prolonged evolution before consulting physician, recurrence, high death-rate.Surgical tactics to be employed in each particular circumstance are discussed.

Sigmoid volvulus is rare and extremely serious; the author presents 7 cases with corresponding documentation and discusses diagnosis and therapy.

The authors present three cases of appendicular mucocele and consider its pathology, clinics and treatment.

Following clínica! observation of a patient the author presents the hypothesis that splenectomy favours an increase of splenic artery flow towards pancreas.and is thus beneficia! to it.

Different techniques have been described for esophago-gastric anastomosis. They are analyzed by the author who also refers to an original method of valvulated suture.

The authors analyze the different techniques employed in coloplasties through out the world and for which a considerable number of case histories areavailable. This type of surgery is difficult, risky and exposed to varied complications. As a result of said analysis it can be stated that: 1) Transverse colon is the most favourable sectoror esophagoplasties. 2) Not only arterial but also venous circulation should be watched· during liberation manouvres; Henle's  venous trunk limits ascent of right end of transplant,consequently the aniso-peristaltic position becomes obligatory. 3) Retrosternal approach, though not devoid of complications, is still the best for oncological surgerywhen it becomes necessary to carry out subtotal resection of esophagus. 4) Esophago-colonic anastomosis in the neck may be complicated by swallowing disorders and consequentpassage of liquids to the bronchi and lung flooding. 5) In non-neoplasic surgery the endopleural approach, if technically correct, is considered by the authors as the most adequate and the one that offersthe best functional results.

The paper contains a revision of 800 cases of diagnostical puncture of the breast. In 737 patients histological study was also performed, but not in the remaining Statistics include 471 benign processes and 266 malign forms. Cytological diagnosis is compared to the histological approach. The method employed is described and findings are analyzed. No false positives appeared. In the case of malign processes, diagnosis was positive in 69,6 % of ali cases. This technique has no adverse consequences for the patient,· provided the tumordiagnosed is adequately treated.
