Abstract

Background

One anastomosis gastric bypass (OAGB) claims its place among bariatric operations, proving itself a safe and effective procedure.

Methods

This is a retrospective analysis of prospectively collected data regarding 94 patients who underwent surgery in a single surgical unit. Tailoring of the biliopancreatic limb length decided upon preoperative BMI was applied. Patients’ excess weight loss and resolution of comorbidities were evaluated. Data on patients’ nutritional status is also presented.

Results

Mean BMI reduction at 36 months postoperatively was 21.7 ± 6.3 kg/m2. Mean excess weight loss (%EWL) was 83.6%, 91.8%, and 92.5% at 12, 24, and 36 months postoperatively, respectively. When controlling for preoperative BMI, a 36-month %EWL of 89.1% for the 2-m subgroup, a 95.3% for the 2.5-m subgroup, and a 104.7% for the 3-m subgroup were found. Operation’s success, defined as %EWL greater than 50%, was 97.9% 36 months postoperatively. All patients suffering from hypertension, diabetes, and dyslipidemia achieved full remission. Furthermore, the percentage of patients with obstructive sleep apnea and gastroesophageal reflux disease, achieving full remission was 91.7% and 86.7%, respectively. An incidence of 5.3% new onset regurgitation was noted. Iron deficiency presented in 26 (27.7%) patients postoperatively, vitamin B12 deficiency in 13 (13.8%), folic acid deficiency in 18 (19.1%), and mild hypoalbuminemia in 7 (7.4%). Major early postoperative complications (Clavien-Dindo grade ≥ 3) were reported in 1.7% of our patients. One (1.1%) patient developed marginal ulcer and two (2.2) patients had late dumping.

Conclusions

OAGB is a safe and efficient technique; however, careful selection of patients and postoperative surveillance with respect to weight regain and nutritional deficiencies are mandatory for optimal results.

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?
