[Do the results of reduction-plasties of the breast justify indications for operation?].

From 1961-1985 we have made by cause of hyperplasia 226 mammaplasties. By continuous follow-up examinations we found out that more than 90% of our patients were quite satisfied with the result and its remarkable that in some cases the women were more happy than the doctor. At all times we have seen a medical indication in order to do a mammaplasty. But before such an operation it seems necessary to analyse the structure of personality. For sake of the surgeon and the surgical method psychopathic personalities should be refused.

[Observations in postoperative ileus].

In the last ten years it was necessary to perform a relaparotomy in 615 cases = 4.93% of 12,464 primary abdominal operations. 215 patients suffered from a mechanical ileus. In analysing 305 cases of the last 5 years it was to discover that of 138 patients the diagnosis mechanical ileus was correct in 102 cases only. In doubtful cases it is therefore advisable to use a water-soluble contrast medium in order to decide for or against surgery. Last but not least the frequency of relaparotomies is clearly dependent on the abilities of the surgeon. In proving this question there were surgeons with 1.2% relaparotomies and others with 18.1%.

[Gastroenterological endoscopy of the upper digestive tract from the surgical viewpoint].

On the basis of an EDP-supported analysis of data which were got in 1,808 endoscopized patients general problems are treated, basing on experiences of a surgicoendoscopic working team. Besides statements concerning the structure of age and sex, indicating signs as well as complication rate the authors adopt a definite attitude to problems of endoscopic care, documentation and training.

[Diagnosis and therapy of intracranial epidermoids].

After a short description of the pathogenesis and morphology of intracranial epidermoids, the clinic symptoms and the diagnosis are dealt with. Therapeutically, it is exclusively a total extirpation with the use of a surgical microscope that can lead to curing. A report is given on nine patients, eight of whom were successfully operated on. It is hardly possible to establish a founded preoperative diagnosis of the kind of the epidermoid. Hypodense space occupying processes in the computer tomogram should, however, give rise to consider differentialdiagnostically also the presence of epidermoids.

[Comparison between the diagnostic findings of esophago-gastro-bulboscopy and standard radiographic diagnosis].

On the basis of a computer-supported evaluation of the data of 1,808 patients who underwent endoscopy (endoscopy of the superior alimentary tract) the comparison of X-ray-findings and findings of the endoscopy could be made in 887 patients. For 124 patients with an oesophageal and gastric tumour, respectively, and for 146 patients with a gastroduodenal ulcer a control of the findings by superordinate parameters (findings of operations and post-mortem examinations) are present. The result was an accordance between 90 and 98%. The accordance of the evidence of the two methods varies depending on the group of diagnosis. For the oesophageal carcinoma it is 90%, for the gastric carcinoma ca. 77%, for the ventricular ulcer and the duodenal ulcer in every case 70%, while the X-ray diagnosis "no abnormality discovered" could be endoscopically confirmed only in 56%. From this result necessary conclusions concerning the further concept of the diagnosis of diseases of the superior alimentary tract.

[The degree of reliability in endoscopic diagnosis].

The histological ascertainment of pathological lesions is one of the most essential advantages and tasks of endoscopy. Of 1,808 patients who underwent endoscopy (oesophago-gastro-bulboscopy) in 620 present results of cellular investigations we could compare with the macroscopic estimation of the findings. 222 times out of 288 patients (77.1%) the diagnosis made--inflammation--could be histologically confirmed. Of 190 malignant tumours the result of this investigation is present for 172 patients. In 29.1% a histological confirmation (exclusive biopsy) could at first not be achieved. Macroscopic estimations of the findings alone are not sufficient, the histologic verification is not in every case at once achievable.

[The value of endoscopy in acute hemorrhage of the upper gastro intestinal tract].

1808 esophage-gastro-bulboscopies were performed, in 156 cases (8.0%) because of acute haemorrhage, from 1975 to 1979. In 14 cases (9.0%) no lesion could be detected. In 3 patients (1.9%) an exact localization of the bleeding lesion could not be attained. Gastric and duodenal ulcerations were (57.1%) the most frequent causes of haemorrhage, followed by erosive lesions (12.8%). Multiple bleeding sources were realized in 24 patients (15.4%). At present endoscopy is the initial method for diagnosing the causes of acute bleeding in the upper digestive tract.

[Complex neurological investigations of space-occupying lesions in the spinal canal (author's transl)].

Problems of early diagnosis of space-occupying intraspinal lesions are discussed in relation to 335 patients on whom surgery had been carried out. Advances in neuroradiological methods are considered. The development of new contrast media has resulted in a reduction of the risk of invasive procedures and this should lead to diagnosis of space-occupying spinal lesions at a very early stage. It is now possible to diagnosis small tumours before they cause compression of the cord or of nerve roots.

[Post-operative lumbar myelogram. Morphology and indications for repeat examinations in patients with disc prolapse (author's transl)].

The morphology and indications for performing post-operative contrast examinations have been analysed in 131 myelograms. Leptomeningeal reactions and adhesions were found in varying degrees of severity in 34 to 75% of post-operative cases; it proved difficult to correlate this finding with the neurological features. The value of repeat myelograms is much reduced after surgery or after previous contrast examinations. It is probable that this is due in part to tissue changes resulting from the surgery or from a proliferative reaction induced by the contrast medium.

[Late meningeal changes after dimer-X-myelography in the absence of surgery (author's transl)].

Myelography with Amipaque was carried out in a group of 28 patients who had had previous Dimer-X-myelography, but no surgery. In 12 cases there was radiological evidence of a meningeal reaction. In all these cases there were chronic changes in the lumbar subarachnoid space. The original myelograms showed no evidence of adhesive changes in the root pouches. It was not possible to correlate the radiological findings of the meningeal changes with the severity or type of neurological diseases.
