[Surgical therapy of the acne tetrad].

On the basis of a 3 years experience with surgical treatment of acne tetrad (acne conglobata, apocrine acne) in 22 patients, we can draw the following conclusions: 1. Radical surgical excision yields better long-term results than local incision. Recurrences are mostly the result of non-radical surgery. 2. In cases of limited acne--especially if it is localized either in the axilla or the groin--primary wound closure may be successfully attained. 3. Gentamycin chains may support the primary wound healing in defect closures of infected areas. 4. In the axilla, we suggest wound closure by myocutaneous island flaps as the best procedure after extensive excision. 5. Specific antibiotic protection, perioperatively, according to previous culture and sensitivity testing can guarantee a postoperative course free from infection. 6. Open wound therapy with secondary healing of the soft tissue defects proved to be the treatment of choice in perineal procedures. 7. In view of the poor prognosis of conservative methods in chronic acne, and because of the risk of subsequent manifestation of chronic septicemia, early surgical excision is desirable.

[Acute appendicitis].

The appendectomy rate in the Federal Republic of Germany has decreased considerably over the past 20 years; in Hannover it has declined by 50%. The number of patients not undergoing operations after hospitalization has increased from 20% to about 65%. Mortality has decreased by 80%, now reaching 0.7 for 100,000 of the population. More than 80% of the deceased are over 65 years old. The main cause of death is advanced appendicitis including perforation. In the North German Patient Appeal Office 10% of all complaints in general surgery concern appendicitis, mostly because of delayed diagnosis. A considerable number of appendectomies is carried out simultaneously in gynecological operations.

[Principles in stenosing surgical disease: multiple-staged surgery (author's transl)].

Colonic surgery today is usually performed in a one-stage procedure. Multiple resection is indicated only for bowel obstruction or severe inflammation. There is some discussion about the necessity of colostomy in left colon resection, mainly in cases of anterior resection. We strongly suggest a double loop transverse colostomy, since anastomotic leaks are frequent even with subtile techniques, and increasingly old high-risk patients have to be operated upon. Also, the fact that younger residents operate is no justification for forsaking this safety measure. According to the literature, most surgeons feel this way.

[Diagnosis and therapy of liver echinococcus (author's transl)].

From 1970 to April 1975 42 patients were treated for Echinococcus of the liver at the Bonn University Dept. of Surgery. There were 33 cases of E. cysticus and 9 cases of E. alveolaris. These two types of Echinococcus, different in parasitology and epidemiology present different clinical manifestation of disease with different course and prognosis. Angiography with celiaco- and superselective hepaticography are decisive for diagnosis. Therapy can only be surgical with total removal of the parasites. In E. cysticus this is almost always possible by enucleation-resection or pericystectomie following evacuation of the cyst and instillation of 20% sodium-chloride or formaldehyde. Such radicality is the exception in E. alveolaris. Here partial resections, biliodigestive and hepatodigestive anastomoses as palliative measures are carried out predominantly to ensure bile passage.

[Catheter embolisation of the splenic artery as treatment for acute bleeding from varices (author's transl)].

Embolisation of the splenic artery with fibrin foam, in order to stop acute bleeding from varices, was carried out in two patients. This was performed immediately after diagnostic arterial indirect demonstration of the portal vein; by this method it is possible to achieve at least a temporary cessation of bleeding from oesophageal or gastric varices. The procedure is indicated in desparate situations, if intubation has been unsuccessful or has had to be discontinued, when endoscopic sclerosis is contra-indicated or when an emergency shunt cannot be carried out because of poor liver function or the general condition of the patient. Permanent results cannot be expected and recurrence of bleeding cannot be avoided. The use of splenic embolisation depends on stopping the acute bleeding in order to obtain an interval during which liver function can be improved so that a decompressing shunt operation becomes possible subsequently.
