“…1995). Generally, aseptic processes such as emphysema, haematoma and seroma are differentiated 59 from septic processes, which include infection and abscess formation (Trede et al, 1982). In cattle, 60 both septic and aseptic processes are often involved in delayed incisional healing after laparotomy 61 (Becker, 1985).…”

The ultrasonographic appearance of the normal abdominal wall in the flank region was investigated before and after exploratory laparotomy in five cows (group A). The results were compared with those after surgical correction of left displaced abomasum in 10 cows (group B) and of caecal dilatation in another 10 cows (group C). We hypothesized that in group C and group B, wound healing would be impaired because of the higher risk of complications compared to group A. A 10.0 MHz linear transducer was used to examine the abdominal wall immediately before exploratory laparotomy and for 10 days (groups B, C) or 30 days (group A) postoperatively. The thickness of the individual layers of the abdominal wall was determined. The skin and the individual muscle layers could be well differentiated via ultrasonography in all the cows preoperatively. In group A, the total thickness of the abdominal wall ranged from 2.80 to 3.40 cm; the skin and the subcutaneous tissues were 0.60 to 0.80 cm, the external abdominal oblique muscle 0.50 to 0.70 cm, the internal abdominal oblique muscle 0.50 to 0.70 cm, the transverse abdominal muscle 0.50 to 0.75 cm, and the transverse fascia and peritoneum were 0.20 to 0.30 cm. Groups B and C had similar findings. There was no significant difference in the course of healing, the thickness of the abdominal wall or thickness of the individual layers during healing among the three groups of cows. Features of healing included subcutaneous emphysema in 19 cows, seroma in 19 and haematoma in 2 cows. However, the occurrence of these events did not differ significantly among the three groups. Ultrasonographic examination of the wound on day 10 postoperatively was unremarkable in 24 cows. A seroma was still present on day 15 postoperatively in one cow of group B. Zusammenfassung: In der vorliegenden Untersuchung werden das ultrasonographische Erscheinungsbild der gesunden Bauchwand im Bereich der Flanke sowie die Befunde bei einer ungestörten Heilung im Anschluss an eine Probelaparotomie von 5 Kühen (Gruppe A) beschrieben. Die gewonnenen Befunde werden mit denen von je 10 Kühen verglichen, die wegen linksseitiger Labmagenverlagerung (Gruppe B) bzw. Blinddarmdilatation (Gruppe C) operiert wurden. Die Ultraschalluntersuchung der Bauchwand erfolgte mit einem 10.0-MHz-Linearschallkopf unmittelbar vor der Laparotomie und während 10 (Gruppen B und C) bis 30 Tagen (Gruppe A) danach. Die Dicken der einzelnen Bauchwandschichten wurden mit den elektronischen Cursormarken gemessen. Präoperativ konnten die einzelnen Schichten der Haut und der Muskulatur ultrasonographisch bei allen Kühen gut von einander differenziert werden. Bei den Kontrollkühen lag die Gesamtdicke der Bauchwand zwischen 2.80 und 3.

Up till now no information could be found by them in the literature concerning the interaction of wound healing disorders with the nosocomial categories of the performed operations. The author's new establishment: as proceeding from category "A" towards category "D", not only the rates of surgical site infections became greater and greater, but those of wound healing disorders, too. But there is an important difference: the increase of the rates of wound healing disorders is in general meaningfully less than that of surgical site infections. Concerning the interaction of wound healing disorders with surgical site infections also another original observation was made by them: if the rate of surgical site infections is less than 2%, the identical rate of wound healing disorders is greater than the rate of surgical site infections and vice versa. If the rate of surgical site infections is greater than 2%, the rate of wound healing disorders becomes less than the rate of site infections. In conclusion the authors think that this relationship between the two sorts of rates - which can be seen in the majority (82.5%) of the rates of wound healing disorders and identical surgical site infections - seems to be fundamental. The interpretation of this observation can be done as follows: all wound healing disorders represent "loci minoris resistentiae" concerning the infection. They don't suppurate, or they scarcely suppurate in the aseptic category "A" and in the facultative septic category "B". On the other hand, more and more of their proportion becomes suppurated in the septic category "C", and even more in the seriously septic category "D". Finally they refer to their guessing, whereby, in an adequate context, the rates of wound healing disorders could be perhaps new indicators in surgical quality assurance.
