Abstract

Purpose

Weight reduction can effectively improve nonalcoholic fatty liver disease (NAFLD), which is a constant companion of severe obesity. This study aimed to determine the effect of one-anastomosis gastric bypass (OAGB) on pathological liver changes in severely obese cases with NAFLD.

Methods

The present prospective research comprised 67 subjects with morbid obesity scheduled for OAGB during the period from February 2015 to August 2018. Clinical, biological, and histologic data were evaluated pre and 15 months postoperatively.

Results

Fifteen months after surgery, a considerable reduction was noted in the grades of fat deposition, liver cell ballooning, and lobular inflammatory changes, in addition to the total NAS score. Fifteen months after surgery, nonalcoholic steatohepatitis (NASH) disappeared in 42% of the patients. A significant regression of fibrosis stage occurred after surgery in 79.1% of patients (p < 0.001). After surgery, patients had substantial reductions in aspartate aminotransferase, alanine aminotransferase, γ-glutamyltransferase, HbA1c, total cholesterol, and Low-density lipoprotein (p < 0.001, for all comparisons). Diabetes mellitus, hypertension, and dyslipidemia resolved in 54%, 59%, and 69% of the patients, respectively.

Conclusion

OAGB resolved NASH from nearly 42% of patients and reduced the histological features of NAFLD 15 months after surgery. Bariatric procedures might be adopted as a therapeutic modality in severely obese cases with NAFLD after the failure of lifestyle modifications.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

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.
