Abstract

This is the first systematic review and meta-analysis focused exclusively on intermediate-term outcomes for the banded Roux-en-Y gastric bypass (B-RYGB). B-RYGB articles published from 1990 to 2013 were identified through MEDLINE, ScienceDirect, and SpringerLink databases augmented by manual reference review. Articles were assigned an evidence level (Centre for Evidence-Based Medicine [Oxford UK] criteria) and Jadad quality score (randomized controlled trials). Simple and weighted means (95 % confidence interval (CI)) for excess weight loss (EWL) at follow-up (1–10+ years) were calculated. At 5 years, a pooled estimate for BMI (kg/m2) change (weighted mean difference and 95 % CI) for banded bypass patients was computed. Rates for weighted mean complications, non-band- and band-related reoperations, and overall comorbidity resolution were calculated. Three hundred twenty-one articles were identified: 286 failed inclusion criteria (i.e., non-English, B-RYGB unrelated, <10 per arm, <3-year follow-up), leaving 35 articles. Manual review added 10 potentially relevant articles; 30 that failed inclusion criteria were excluded, leaving 15 for analysis. B-RYGB was performed on 8,707 patients: 79.0 % female, mean age 38.7, and BMI 47.6 (41.0–59.4). Overall BMI weighted mean difference (reduction) at 5 years was 17.8 (95 % CI 12.8, 22.7; p < 0.001). Five-year weighted mean EWL of 72.5 % (67.5, 77.4) was sustained at 10+ years (69.4 %; 58.9, 80.0). Weighted mean complication rates were as follows: early, 10.9 %, and late, 20.0 %. Non-band-related reoperation rate was 15.2 %, and band-specific reoperation rate was 4.1 %. Gastric outlet stenosis, band erosion, and band slippage were 2.8, 2.3, and 1.5 %, respectively. Diabetes remitted in 80/95 (84.2 %). By systematic review and meta-analysis, albeit with limited rates of follow-up, B-RYGB appeared to result in significant, sustained excess weight loss of approximately 70.0 % out to 10 years.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

CME: 2 Punkte

Prof. Dr. med. Gregor Antoniadis Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.

Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
