    Description / Table of Contents: Résumé Six femmes et 39 hommes ont été traités entre janvier 1985 et décembre 1988 d'un sinus pilonidal non enflammé au moyen de sclérothérapie. En anesthésie locale, 1 à 2 ml d'une solution à 80% de phénol sont injectés dans le sinus. Le phénol est laissé en place durant 1 minute puis le sinus est irrigué avec une solution physiologique habituelle. Un questionnaire a été envoyé à 45 patients; 37 questionnaires sont utilisables pour l'évaluation. Une guérison compléte survient chez 22 patients (59,5%). Le temps de guérison moyen est de 6,2 semaines. En dehors d'une rougeur transitoire observée fréquemment en réponse á une inflammation causée par le phénol, 5 patients ont développé un abcès nécessitant un traitement chirurgical. Cette étude ne confirme donc pas les résultats encourageants d'autres séries.
    Notes: Abstract Six female and 39 male outpatients, who suffered from acutely inflamed pilonidal sinus were treated by sclerotherapy between January 1985 and December 1988. Under local anaesthesia, 1–2 ml 80% phenol was injected into the sinus. The phenol, which was allowed to act for a minute, was washed out by irrigating the sinus with physiological common-salt solution. Of the questionnaire sent to all 45 patients, 37 proved suitable for evaluation. Complete healing occurred in 22 cases (59,8%). The healing time was 6.2 weeks on average. Besides a rather frequently observed transient reddening as a result of the local inflammation caused by the phenol, 5 patients developed an abcess which needed operative treatment. This study does not support the encouraging results of previous series.

    Description / Table of Contents: Zusammenfassung Eine neu entwickelte laparoskopische Tabaksbeutelnahtklemme bietet in Kombination mit dem biofragmentierbaren Valtrac®-Ring die Möglichkeit, Anastomosen im Dünn- und Dickdarm intrakorporal ohne Stapler zu erstellen. Im Rahmen der hier vorgestellten tierexperimentellen Studie wurde bei 5 Schweinen eine End-zu-End-Anastomose im Colon descendens gebildet. Die Nachuntersuchung erfolgte bei 4 Tieren nach 21 Tagen und bei einem Tier am 1. postoperativen Tag. Eine Anastomoseninsuffizienz war in keinem Fall festzustellen. Die Anastomosen der Tiere, die 3 Wochen postoperativ nachuntersucht wurden, wiesen sowohl makroskopisch als auch histologisch nur geringe Narbenbildung auf. Die hier vorgestellte Anastomosentechnik könnte in Zukunft eine Alternative zu den assistiert laparoskopischen Eingriffen am rechten Kolon darstellen.
    Notes: Abstract In combination with the biofragmentable Valtrac ring a newly developed purse-string suture clamp offers the possibility of performing intraperitoneal anastomoses of the small and large bowel without the need for stapling devices. During this experimental study endto-end anastomoses of the descending colon were constructed in five pigs. One animal was re-examined on day 1 after the operation and the others were all sacrificed on day 21 after. None of the animals showed any signs of an anastomotic leakage. Little scar tissue was seen macroscopically or histologically in the anastomotic region of the animals sacrificed 3 weeks after the operation. The operative technique presented in this paper might render the so-called assisted laparoscopic procedures for the right hemicolon unnecessary in the future.

    Notes: Abstract The morphological changes in rat facial muscles were evaluated after permanent denervation and were compared with findings after immediate reinnervation. Thirty rats underwent transection of the left and right facial nerves immediately followed by hypoglossal-facial nerve anastomosis on the right side (muscular reinnervation) and removal of 8–10 mm of the facial plexus on the left side (permanent muscular denervation). Levator labii muscle samples of both sides were collected sequentially at 2, 6, 7, 10, 20, and 24 weeks after surgery and submitted to routine histological and enzyme histochemical staining procedures. In normal levator labii muscles a typical “chessboard” pattern was found, with type I fibers being smaller than type II fibers. These latter fibers also were more prevalent than the type I fibers. Among the type II fiber subtypes, the type IIB fibers were larger and more frequent. Two weeks after surgery, there were no differences between denervated facial muscles and those undergoing reinnervation. Both showed atrophic myofibers among normal-sized fibers and slight fibrosis. Those muscles denervated for more than 2 weeks displayed increasing fiber atrophy with frequent loss of typability, as well as proliferation of connective tissue and fat cells in perimysial and endomysial sites. After denervation for 20 weeks only a few atrophic fibers were found in wide areas of fibrosis and fat cells. Following nerve anastomosis the reinnervated levator labii muscle showed much less fiber atrophy. Regrowth to normal fiber diameters was found with only a few atrophic myofibers 10 weeks after anastomosis although a moderate fibrosis predominated at perimysial sites. Reinnervated facial muscle fibers displayed a typical type-grouping pattern and also frequent lack of typability.
