    Description / Table of Contents: Zusammenfassung. Zwischen 1984 und 1996 wurde an unserer Klinik bei der Behandlung der morbiden Adipositas die Gastroplastik nach Mason an 14 Patienten im Alter von 40 (26–48) Jahren, Body-mass-Index (BMI) 48 (37–71) kg/m2, Übergewicht 67 (41–116) kg durchgeführt. Seit Dezember 1996 wenden wir das justierbare laparoskopische „gastric banding“ (Lap-band) an: 73 Patienten im Alter von 39 (22–64) Jahren, BMI 45 (32–69) kg/m2, Übergewicht 66 (30–169) kg. Wir untersuchten Früh- und Spätresultate beider Methoden. Frühresultat: Bei beiden Methoden beobachteten wir keine relevante Morbidität und keine Letalität. Spät/Intermediärresultat: Reoperationsrate 15 % bei beiden Methoden. Nach Gastroplastik war die Abnahme des Übergewichts nach durchschnittlich 3,7 Jahren 54 (22–96) %, nach Lap-band bei 24 Patienten nach 12 Monaten 47 (11–127) % und bei 8 Patienten nach 18 Monaten 51 (28–139) %. Seit Einführung der laparoskopischen Technik hat die Anzahl bariatrisch-chirurgischer Eingriffe stark zugenommen. Dennoch blieben die Komplikationsrate gering und das Spätresultat vergleichbar.
    Notes: Summary. Between 1984 and 1996 we performed a Mason gastroplasty for the treatment of morbid obesity: 14 patients (average age 40 (26–48) years, body mass index (BMI) 48 (37–71) kg/m2, excessive body weight 67 (41–116) kg). Since the end of 1996 we now apply adjustable laparoscopic gastric banding (lab band): 73 patients (average age 39 (22–64) years, BMI 45 (32–69) kg/m2, excessive body weight 66 (41–116) kg). We compared the early and late results of both methods. Early results: no relevant morbidity or mortality for neither method. Late/intermediate results: reoperation rate for both methods 15 %. After an average of 3.7 years the excessive body weight loss (EWL) for gastroplasty was 54 (22–96) %. The EWL after lab band for 24 patients after 12 months was 47 (11–127) % and for 8 patients after 18 months 51 (28–139) %. Since the introduction of the lap band the number of bariatric operations has greatly increased. Nevertheless, the perioperative complication rate has remained low, and the long-term outcome is similar for both methods.

    Notes: The partially diethylamino substituted phenyl-chloromono- and -disilanes Cl2Ph(NEt2)Si(2) Cl2Ph(NEt2)2Si(3), [ClPh(NEt2)Si-]2 (7) and Cl(NEt2)PhSi—SiPh(NEt2)2 (8) were synthesized. 3 and 8 are able to react with lithium powder to form the corresponding silyllithium compounds. The resulting species were characterized in solution by 13C and 29Si NMR spectroscopy. To prove the expected substitution patterns of the silyllithium compounds some coupling reactions with chlorosilanes were carried out and the resulting new oligosilanes were characterized by means of NMR spectroscopy and MS.

    Notes: Preparation and Characterization of Oligomeric as well as Polymeric Ethynylsilanes Containing Si2—Si4 UnitsThe treatment of methylchlorodisilanes with ethynyldigrignard (BrMgC≡CMgBr) resulted in oligomeric as well as polymeric ethynyldisilanes. The kind of this products is related to the chloro functionality of the starting disilane. The reaction of SiClMe(SiCl2Me)2 as well as SiMe(SiCl2Me)3 yielded polymers beside small amounts of the monomeric products (HC≡C)MeSi[SiMe(C≡CH)2]2 and MeSi[SiMe(C≡CH)2]3.
