[Infected pilonidal sinus].

During the past 11 years (1985-1996), 324 patients with pilonidal sinus were treated. In 272 cases primary wound closure was performed, in contrast to 52 cases with secondary wound healing. One hundred and fourteen patients were additionally treated with an antibiotic carrier (group 1), 158 were not (group 2).

[Effectiveness of various methods of stopping hemorrhage in spleen and liver injuries--results of an animal experiment study].

In 40 wistar rats liver and spleen were traumatized under standardized conditions. The hemorrhage was stopped by four different methods: 1. traditional suture technique with 4 X 0 Catgut, 2.

Monocytogenic endothelialization in dacron grafts. Experimental studies on rats.

The cytogenetic relationship between cells of the hematopoetic system and prosthesis lining cells is still not known. The purpose of this experimental study was to determine to what degree blood monocytes may be transformed into those cells which line the inner surface of vascular grafts. Immunological identical rats (donors = 25) were pretreated with a total dose of 150 micrograms C 3H-thymidine.

Pseudo-endothelial cell growth on auto-alloplastic vascular prostheses. Experimental studies on rats.

Pseudo-endothelial cell growth on Sparks' auto-alloplastic vascular prostheses which had been grafted in the arterial circulatory system are examined by light- and electron microscopy at different intervals after application. The obtained data clarify that in future we should speak of prosthetic endothelium or lining cells when referring to those cells which line the inner surface of prostheses; the present study reveals that these cells lack some important criteria, e.g.

[The effect of vasopressive drugs in managing bleedings from oesophageal varices and the intestinal tract (author's transl)].

The therapeutic effect of TGLVP a new hormonogen of vasopression in demonstrated in a pilot study: 9 patients suffering from bleeding oesophageal varices (in total 16) could be sufficiently treated by TGLVP, as well as 9 patients (in total 13) with abdominal haemorrhage of unknown aetiology and localization. Good results can be expected by TGLVP to bring gastrointestinal bleedings to a standstill.

[Experimental microsurgery in rats (author's transl)].

Experimental microsurgical techniques using a magnifying glass and surgical microscope enable nearly all abdominal operations and organ transplantations to be performed in rats. Vascular and prosthetic segment implantations, portocaval anastomoses, heterotopic heart-, kidney-, spleen-, pancreas-, and liver transplantations some with superselective organangiography, are excellently demonstrated. Continuing research in microsurgery has considerably expanded experimental surgery and given new impulse to clinical surgery.

[Current aspects in the endothelialization of artificial prostheses (experimental studies in rats)].

The interaction between the blood and the inner prosthetic wall after grafting with the autoalloplastic SPARKS prostheses was examined by light and electron microscopy as well as by autoradiography. The results indicate that intercellular bridges are missing, and therefore that those cells that line the inner surface of the prosthesis are no real endothelial cells, as observed with the electron microscope. The authoradiographic findings demonstrate that blood monocytes definitely contribute to the construction of the new inner surface.

[Complications of arterial reconstructions below the knee for chronic vascular occlusion (author's transl)].

From 1967 to 1976 49 reconstructions were undertaken in the area distal of the art. poplitea: 30 femoral-crural bypasses, 12 TEA und 7 orthogradic desobliterations. Complications until clinical demission were reviewed.

[Surgery for coarctation of the aorta in the first year of life (author's transl)].

A new surgical repair of coarcation of the aorta is reported on 7 infants in the first year of life. Hereby the subclavian artery is used as a modified patch for the coarctation and utilised for re-establishing aortic continuity. The results and advantages are presented and discussed.

[Significance of various implantate localizations of Sparks prostheses, experimental studies in rats].

Our investigations show that Sparks prostheses after subcutaneous implantation are suitable for vascular grafting. At the end of the organization period the connective tissue becomes strong, and after the third and fourth weeks collagenous and elastic fibers can be seen. Ten weeks after s.

[Complications of arterial reconstructions for chronical ischemia of the lower limbs (author's transl)].

547 operations performed for reconstruction of 637 chronically occluded arterial segments in the aorto-iliac and the femoro-popliteo-crural stages were analyzed for occurred complications. Lethal event as the gravest complication happened in 4.6 p.

Local postoperative complications after surgery of the cardia.

602 patients had an operation on the cardia of stomach during 10-year period 1964-1973 in the Surgical Department of Kiel University. In total there were 395 operations without resection with a 9% postoperative complication rate opposite to 207 resections of the cardia with 38% complications. Here the primary lethality was 7% (14 patients).

[Histological and histochemical evaluation of the cellular infiltration of s.c. implanted sparks prothesis. Experiments on rats (authors transl)].

Sparks-prothesis of 3 mm diameter were implanted into inbred rats and withdrawn after one to ten weeks. They were then fixed in Formalin and embedded in Paraffin and Metachrylat. After cutting (2.
