Abstract

Abnormal anatomic findings are a major concern before performing bariatric surgery, while pathological changes are considered less often. The present study aimed to investigate the incidences of gastric lesions warranting follow-up in patients undergoing bariatric surgery. Meta-analyses were conducted to calculate the pooled incidences of gastric lesions in patients undergoing bariatric surgery. Fifty-nine studies including 32,789 patients were included: 26 on endoscopic biopsy, 26 on pathological findings of the excised specimen, five on the intraoperative exploration results, and two on both preoperative endoscopy and postoperative specimen. Generally, atrophic gastritis (3.05% (95% CI (confidence interval) 1.53–6.09)), intestinal metaplasia (2.44% (95% CI 1.76–3.25)), and GIST (gastrointestinal stromal tumor) (0.45% (95% CI 0.31–0.60)) were not rarely found. Routine preoperative endoscopy was applied in 16 studies, and the pooled incidences of atrophic gastritis and intestinal metaplasia were 2.64% (95% CI 0.78–8.9) and 2.70% (95% CI 0.9–5.42), respectively. Hp. (Helicobacter pylori) screening and eradication were routinely performed in 10 studies, and that was related to a reduced incidence of atrophic gastritis (0.94% (95% CI 0.03–2.92)) vs. 4.31% (95% CI 2.01–9.23). GIST was more likely to be found by intraoperative exploration than by preoperative endoscopy (0.68% (95% CI 0.50–0.93) vs. 0.23% (95% CI 0.11–0.52)). Patients undergoing bariatric surgery demonstrated non-negligible incidences of gastric pathologies warranting follow-up. Preoperative endoscopy and careful intraoperative exploration should be routinely performed, and Hp. screening and eradication are suggested before endoscopy. In condition that such findings are detected, sleeve gastrectomy may be preferred over Roux-en-Y gastric bypass.

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?
