Abstract

Aim

The aim of this retrospective study was to evaluate the frequency and risk factors of urinary dysfunction after autonomic nerve-preserving surgery for rectal cancer.

Methods

This was a retrospective multiinstitution study of 1002 rectal cancer patients conducted between January 2008 and December 2012 in Yokohama Clinical Oncology Group. Patients who had preoperative urinary dysfunction or had not undergone autonomic nerve preservation surgery were excluded. Urinary dysfunction was defined as that with a Clavien-Dindo classification grade ≥ 2. Patient-, tumor-, and surgery-related variables were examined by univariate and multivariate analyses.

Results

A total of 887 patients were analyzed. Postoperative urinary dysfunction was observed in 77 patients (8.8%). A multivariate logistic analysis showed that a tumor location in lower rectum (odds ratio [OR] 2.16; 95% confidence interval [CI] 1.15–3.71; p = 0.02), tumor diameter ≥ 40 mm (OR 2.07; 95% CI 1.19–4.44; p < 0.01), operation time ≥ 240 min (OR 2.07; 95% CI 1.19–4.44; p < 0.01), blood loss ≥ 300 ml (OR 2.35; 95% CI 1.12–3.84; p = 0.02), and diabetes (OR 3.26; 95% CI 1.80–5.89; p < 0.01) were independent risk factors of urinary dysfunction. The incidence of urinary dysfunction exceeded 20% in patients with 3 preoperative predictors (tumor location, tumor diameter, diabetes).

Conclusions

This result demonstrated that high-risk patients with more than two risk factors should be informed of the risk of urinary dysfunction.

Echinokokkose medikamentös behandeln oder operieren?

06.05.2024 DCK 2024 Kongressbericht

Die Therapie von Echinokokkosen sollte immer in spezialisierten Zentren erfolgen. Eine symptomlose Echinokokkose kann – egal ob von Hunde- oder Fuchsbandwurm ausgelöst – konservativ erfolgen. Wenn eine Op. nötig ist, kann es sinnvoll sein, vorher Zysten zu leeren und zu desinfizieren. 

Wie sieht der OP der Zukunft aus?

04.05.2024 DCK 2024 Kongressbericht

Der OP in der Zukunft wird mit weniger Personal auskommen – nicht, weil die Technik das medizinische Fachpersonal verdrängt, sondern weil der Personalmangel es nötig macht.

Umsetzung der POMGAT-Leitlinie läuft

03.05.2024 DCK 2024 Kongressbericht

Seit November 2023 gibt es evidenzbasierte Empfehlungen zum perioperativen Management bei gastrointestinalen Tumoren (POMGAT) auf S3-Niveau. Vieles wird schon entsprechend der Empfehlungen durchgeführt. Wo es im Alltag noch hapert, zeigt eine Umfrage in einem Klinikverbund.

Recycling im OP – möglich, aber teuer

02.05.2024 DCK 2024 Kongressbericht

Auch wenn sich Krankenhäuser nachhaltig und grün geben – sie tragen aktuell erheblich zu den CO2-Emissionen bei und produzieren jede Menge Müll. Ein Pilotprojekt aus Bonn zeigt, dass viele Op.-Abfälle wiederverwertet werden können.

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.
