“…Morphologie des intestinalen Neosphinkters: Das in der Mesenterialebene aufgeschnittene entfaltungsfixierte Prfiparat zeigt deutlich die kompaktverheilte Dreischichtung des Neosphinkters sichtspunkten die Nippel-Valve-Anastomose die beste Funktion zu besitzen [11]. Wfihrend die Technik zur muskelschonenden und blutsparenden Entfernung der Rektummukosa bereits vor fiber 10 Jahren am Mr. Sinai Hospital in New York standardisiert worden war, haben wir das Verfahren analog an der Kolon-und Ileummukosa und erstmals an der Ileumserosa angewandt [6,9]. In Zeitabh~ingigkeit ist also ein Funktionsverlust zu erwarten, der durch morphologische Instabilit~it infolge Nippelgleitens eintritt.…”

In an experimental study an intestinal neosphincter (INS) was constructed by modifying the principle of the ileocolic nipple-valve anastomosis by means of ultrasonic tissue fragmentation of the contacting serosa of the ileum and the corresponding mucosa of the ileum and colon. The healing of the muscle layers was studied histologically. The function of the INS was investigated in six dogs and compared intraindividually with that of the ileocecal valve and conventional end-to-end anastomosis. Morphologically the neospincters healed within 3 months without major fibrosis. The reference values of the aerobic and anaerobic bacterial counts in the terminal ileum were more than 2 logs lower than in the colon with the normal ileocecal valve, and after ileo-colonic end-to-end-anastomosis bacterial colonization of the terminal ileum was found both qualitatively and quantitatively. Subsequent interposition of the INS led to bacterial clearance of the terminal ileum. The median aerobic bacterial counts were lower by six logs and the an aerobic bacterial counts by 3 logs than in the colon. However, differences were not statistically significant owing to the wide variation in the individual values. Nevertheless, the demonstrable clearance of the terminal ileum could be explained by the orthograde passage with absolutely no stagnation and the relative competence of the INS in resisting retrograde pressure competence. In conclusion, ultrasonic fragmentation of the serosa and mucosa of the bowel allows construction of an INS from three muscle layers, which acts as a bacteriological barrier. Before it is introduced into the clinical setting its integration into the intestinal motility should be evaluated by further studies.

“…After a short time, however, neurosurgeons and general surgeons realized the tremendous potentialities of this instrument, which underwent several improvements until the present form was reached. Also, a series of clinical and experimental studies were published on ultrasonic aspiration in neurosurgery and general surgery [1,2,3,4,5,9,10]. It was established that ultrasonic aspiration produced no deleterious physiological effects on nervous tissue [10].…”
