Abstract

Background

The Roux-en-Y gastric bypass (RYGB) still remains the gold standard in bariatric surgery. However, no consensus exists on the optimal limb lengths to induce maximum weight reduction. The aim of the present study was to assess the effect of a longer alimentary limb (AL) length on weight reduction after RYGB.

Methods

A retrospective analysis of a prospectively collected database of patients who underwent a primary laparoscopic RYGB between January 2001 and March 2011 was performed. Patients received a short AL (SAL; 100 cm) or a long AL (LAL; 150 cm). Primary outcome was weight loss, and secondary outcomes were short- and long-term complication rates.

Results

A total of 768 patients received a RYGB during the study period. Of these, 730 consecutive patients were included for long-term analysis and had a mean follow-up (FU) of 37 ± 26 [range 0–120] months; 360 (47 %) patients received a SAL RYGB. Overall %TBWL was 33 ± 9 % after 2 years (FU 74 %) and 28 ± 12 % after 5 years (FU 20 %). No significant differences in %TBWL were found between SAL RYGB and LAL RYGB during the study period. The 30-day mortality rate was 0.13, 9 % overall short-term complication rate and 19 % cumulative long-term complication rate. No differences in complications were found between SAL and LAL RYGB patients.

Conclusion

Lengthening of the alimentary limb from 100 to 150 cm did not affect post-RYGB weight loss. Overall complication rates were low and comparable in this series of RYGB patients.

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.

S2e-Leitlinie „Distale Radiusfraktur“

CME: 2 Punkte

Dr. med. Benjamin Meyknecht, PD Dr. med. Oliver Pieske Das Webinar S2e-Leitlinie „Distale Radiusfraktur“ beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. 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?
