Abstract

Background

The new global epidemic, overweight and obesity, has a significant role in the etiology of liver tumors. However, the impact of body weight on the outcome after liver resection is unknown.

Methods

We carried out a prospective study of 684 patients who underwent liver resections. Patients were stratified according their body mass index (BMI) as follows: normal (<25 kg/m2) (52%), overweight (25–29 kg/m2) (34%), and obese (≥30 kg/m2) (14%), and according to the extent of resection, as either minor or major hepatectomy. Preoperative and intraoperative characteristics and outcomes were prospectively studied. The Dindo–Clavien classification of morbidity was used.

Results

Overall postoperative morbidity and morbidity rates were not influenced by BMI. Pulmonary complications were significantly more frequent in obese patients irrespective of the extent of resection. During major resection obese had longer pedicular clamping and more frequently required blood transfusion. After major resection, major morbidity (Dindo–Clavien grade III or more) was more frequent in obese (57%) and overweight (54%) patients than in patients of normal body weight (35%; P < 0.05), including a higher rate of respiratory complications and ascites and longer intensive care unit (ICU) and hospital stays. Obesity and overweight were independent predictors of major morbidity (OR 2.6, 95% CI 1.2–5.8 and OR 1.9, 95% CI 1.2–3.2, respectively), and obesity was a predictor of the need for blood transfusion (OR 3.3, 95% CI 1.4–7.9) after major resections.

Conclusions

Obese and overweight patients are at increased risk of potentially life-threatening morbidity after major hepatic resections. Because the risk of mortality is not increased significantly, there is no justification for a compromise in the indication or extent of surgery.

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.
