    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: Abstract In rectal cancer, depth of infiltration and metastatic involvement of lymph nodes are important prognostic factors. The correct choice of operative treatment depends on the extent of the disease. In a prospective study, the value of endorectal ultrasound in staging rectal cancer was evaluated, and factors affecting the method's accuracy are discussed. The overall accuracy in staging depth of infiltration was 89 percent. Overstaging occurred in 10.2 percent, understaging in 0.8 percent. Tumors of the lower rectum are incorrectly staged in 16.7 percent, whereas tumors of the middle and upper rectum had an incorrect staging in 6.3 percent (P 〈0.001). Compared with computed tomography, endorectal sonography is the more accurate staging method (74.7 vs.90.8 percent). In staging lymph nodes, the overall accuracy was 80.2 percent, sensitivity was 89.4 percent, specificity was 73.4 percent, positive predictive value (PPV) was 71.2 percent, and negative predictive value (NPV) was 90.4 percent. The staging accuracy depends on the size of the node. Endorectal ultrasound is a safe, inexpensive, and accurate staging method, in the assessment of both depth of infiltration and nodal status. The results are strongly related to the experience of the investigator.
