[Postoperative recurrent nerve paralysis after initial interventions for benign goiter].

Between January 1st, 1979 and December 31st 1993, 2501 operations for benign diseases of the thyroid gland were performed. The documentation was done prospectively. The operation technique remained the same during these years. The recurrent laryngeal nerve wasn't routinely identified. All together we saw 0.6% permanent vocal cord palsies. The incidence of nerve paralysis was correlated to the size (weight), to the expansion of the goiter, to the performed operative procedure and to patients' age and gender.

[Important epidemiologic aspects of appendicitis].

In the past 20 years the frequency of appendectomies has been halved. The reason of this lies in the strictly indication for operation. A perforation rate more than 10% and a sex relation 1:1 point at a balanced indication.

[Assessing performance in new German states].

With the disbandment of the G.D.R., the following also ended: a) the central registration of all inpatients, which allowed statements to be made about hospital morbidity; b) the central tumor documentation, in which all tumor patients were registered up to 5 years after first treatment. Data relating to the clinic are being set up. We present a proven program of operating statistics set up by the working group for quality assurance.

[Analysis of the frequency of blood transfusion in surgery].

For the period from 1985 to 1987 were analysed the blood transfusions, which were carried out in seven surgical wards, within the scope of a study for quality assurance. 7.6% of the patients, treated in surgical ward and 5.4% of the patients, treated in traumatological ward, were given blood transfusion. The average was 3.6 transfusional units per treated patient. The biggest differences were to be remarked at cases of breast cancer and at thyroid gland surgery. The average transfusion frequency at breast cancer was 16% with a difference between 5 and 63%. In thyroid gland surgery the average transfusion frequency was 11%, differing between 1 and 54%. At these operation groups the blood transfusion were usually given once. Transfusional reactions, costs and responsibility towards the donor demand a turning away from scientifically non-established transfusion habits. The components concept by Lundsgaard should serve as an orientation.

[Clinical aspects of appendicitis].

When evaluating 4232 appendectomies between 1977-1986 there were 12.5% perforations and in 19.3% the diagnosis was not justified. In 5.1% surgical intervention was done without acute appendicitis. The overall lethality was 0.5%, the cases of perforation 2.3%. The diagnosis of lethality was cardiopulmonary disease. In this follow up study we discuss possibilities of giving a secure diagnosis.

[Status determination in discussion of benign stenosis of Vater's papilla].

Inflammatory and cicatrical alterations are the morphological basis of papillary stenosis in most cases due to canalicular or lymphatic spreading of bacterial infection in gallstone disease. The consequences of papillary stenosis are elevated pressure in the ducts and reduced bile flow. At surgery you find dilatation of the bile ducts, increase of residual pressure, decrease of outflow, and--in cicatrical stenosis--stop for the probe. Only the inflammatory stenosis is reversible, but permanent alteration is not to determine. Therefore therapy is necessary, at first instrumental dilation to 4-6 mm. Impossibility of dilatation indicates transduodenal sphincterotomy. Recurrencies are best treated by endoscopic sphincterotomy and exceptionally by choledochoduodenostomy.

[Appendicitis from an epidemiological viewpoint].

A general CDR-wide account is given in this paper of hospitalised treatment, frequent of operations, and lethality of appendicitis. Hospitalised treatment declined from 97.208 to 52.814 cases, i.e. by 46 percent, between 1971 and 1988. In 1988, ratios were 30.7 top 10,000 males and 32.7 to 10,000 females. The ratio of surgery was 21 to 10,000, with declining trend. Hence, about one third of all hospitalised patients were cases for observation rather than treatment. The decline has been attributable to more stringent criteria for surgery. Decline in frequency of operations has been accompanied by reduction in lethality and mortality. Overall lethality of acute forms of appendicitis has been 0.4 percent in 1988, which was primarily attributable to improvement of therapeutic methods. The mortality rate to 10,000 inhabitants is 0.15.

[Benign stenosis of Vater's papilla from the pathogenetic viewpoint].

Data and surgical findings recorded from 7,640 primary operations on bile ducts were analysed and were investigated for their relationship with benign stenosis of Vater's papilla. Positive diagnosis of the latter was made in 487 cases (6.3 per cent). Clearly discernible correlations were found to exist between papillary stenosis, on the one hand, and severe chronic inflammation of the gall-bladder and choledocholithiasis, on the other. A relationship between papillary stenosis and advanced age was to some extent suggested by increased occurrence of severe chronic inflammations and choledocholithiasis in higher age groups. Primary stenosis without causative inflammation in the vicinity of the papilla was not recordable from the above surgical cases. The view has been confirmed that benign stenosis is likely to develop as a secondary alteration due to inflammatory processes along with lithiasis.

[Validation of intraoperative diagnostic criteria in the differentiation of benign stenoses of Vater's papilla].

The following criteria were recorded from complex intraoperative bile duct diagnosis and were recalculated for validation: residual pressure, flow per minute, choledochal width, and possible probing of the papilla. A comparison was made between 189 cases of papillary stenosis without accompanying choledocholithiasis, on the one hand, and cases with non-contributory choledochus, on the other, for the period from 1970 to 1984. Probabilities by which presence of papillary stenosis could be established were 83 per cent by debitomanometry or 91 per cent by enlargement of choledochus in conjunction with possible probing of the papilla. With all four criteria tested, the probability went up to 99.9 per cent. Diagnosis of papillary stenosis thus proved to be possible with high probability by combination of several examination methods.

[Is dilatation of the papilla a differential diagnostic or therapeutic intervention?].

Calculations were made to establish the action of probes of different thickness on both cicatric tissue and unstriated muscles of the major duodenal papilla. The findings are graphically represented. These calculations were based on histopathological findings recorded from the major duodenal papilla, expandibility, of collagenic fibres and unstriated muscles, and morphometric measurements. The conclusion was drawn that passage of a probe of more than 3 mm in diameter through a cicatrically narrowed papilla constituted an act of therapy or at least had a therapeutic component in addition to probing. The therapeutic range of papillary dilatation is limited to something from three to six millimetres.
