[Videodensitometry analysis of stomach wall motility--presentation of a new method].

The videodensitometry is a suitable method for recording the gastric wall motility. It provides biosignals amenable by computer. There are no special demands to any organic form or kind of contraction. The asymmetry of the stomach makes no difference, therefore. The hitherto usual manometry will not be superseded. Both methods complete themselves in an ingenious manner. The radiation exposure by videodensitometry can be diminished by modifying the system for image causation.

[Bengmark spleen transposition in children].

After a historical review of surgical therapy of portal hypertension experiences are reported with the technique of spleen transposition according to Bengmark in a group of six children. Two thirds of the spleen are removed and the rest is implanted into the abdominal wall. This causes development of subcutaneous portosystemic anastomosis. The method is a true alternative to portosystemic shunt operations.

[Surgical therapy of rectal cancer].

Surgical excision of rectum carcinoma by amputation, resection or locally delimited excision has remained to be the optional curative approach to carcinoma of any position, severity, type and phase. Low-dose heparinisation, oral intestinal washing, and perioperative application of antibiotics have retained their established positions in the run-op to surgical action. The value of perioperative radiotherapy is still unelucidated. Chemotherapy has so far failed to produce a safe adjuvant effect. The age limit to curative intervention is continuously moved upwards. Resection is more often chosen than other approaches. Safely established knowledge is likely to suggest that the atumorous aboral safety zone may be reduced to 2 cm, provided that the perirectal lymphatic channels are severed at equal level. Anastomosis in cases of deeper anterior removal can often be sutured only by staplers. There is a growing number of situations in which the approach can be taken without preceding colostomy. Transanal and transsphincteral access routes are available for locally delimited tumour excision. Postoperative lethality has been continuously lowered and is now below five per cent. Reported in this paper are the authors' own results over the past decade.

[Value of the 14C-aminophenazone inhalation test: inhibition of the demethylation function of the liver by cimetidine].

On 15 patients with healthy liver and with a peptic ulcer the demethylation capacity of the liver was measured with the 14C-aminophenazone breathing test before the treatment and during the treatment with the H2-antagonist cimetidine (daily dose 1.0 g). As measure of the demethylation capacity the breathed out 14CO2 (DPM/mmol CO2/70 kg body weight) before and 1 hour after intake was chosen. Under influence of cimetidine the mean 14CO2-value of 724.7 DPM (S.D. 127.7) decreased to 404.1 DPM (S. D. 153.1). The enzyme activities (ALAT, ASAT, AP, AAP, GGT, CHE) and the concentrations of serum bilirubin and serum albumin remained unchanged and did not correlate mutually and with the 14CO2-data. The results confirm the independence of the aminophenazone test as technique for the recognition of disturbance of the MFO-system.

[Dental care of prison inmates in Switzerland].

The dental status of inmates of 10 Swiss penitentiaries (capacity 50 to 245 persons) was investigated, and also organization and economic questions pertaining to dental treatment of penitentiary inmates. In all 10 institutions, the minimal claims of the UNO (1955) relative to dental treatment of penitentiary inmates are fulfilled. Nevertheless, there are significant differences between the 10 institutions. In some, practically only pain therapy is customary, while in others the whole spectrum of modern dentistry is used. Preventive measures are uniformly insufficient. Since the administering of punishment in Switzerland is cantonal, the differences in dental treatment will not be easy to eliminate.

[Complications and risks of abdominal diseases in old surgical patients (author's transl)].

732 patients older than 70 years suffering from abdominal diseases were studied regarding postoperative complications and mortality. The rate of complications in connection with surgical procedures corresponds to that of younger patients. But complication depending on organs and organ systems impaired by age and pre-existing diseases were found in higher percentage.

[Results of treatment of cholelithiasis and its consequences; the so called "postcholecystectomy-syndrome" (author's transl)].

Our analysis of 378 patients made after operations for diseases of the gallbladder and bile tract underlines the demand of an exact preoperative diagnostic examination of other abdominal organs, e.g. the oesophagus, stomach, duodenum, liver and pancreas. The value of using modern intraoperative diagnostic procedures for the biliary tract is confirmed. Our analysis also demonstrates the necessity of traeting cholelithiasis surgically at an early stage. Complications of cholelithiasis include a higher risk, a worse prognosis with regard to permanent healing and a higher rate of postoperative lethality.
