Abstract

Background

The aim of the present study was to perform a systematic review and meta-analysis of cancer-specific outcomes after curative rectal cancer surgery comparing anastomotic leak (AL) with no leak.

Methods

PubMed, Medline and Embase databases were searched to identify studies comparing cancer-specific outcomes after rectal cancer surgery in patients with AL and without. A meta-analysis with a random-effects model was used to calculate pooled odds ratios (OR) and confidence intervals (CI) for each outcome measure.

Results

A total of 18 studies were included for meta-analysis, comprising a total of 18,039 patients after curative rectal resection (1764 AL, 16,275 without AL). The overall rate of AL was 9.8%. After AL and excluding 30-day mortality there was an increased risk of local recurrence (OR 1.50; CI 1.23, 1.82), worse overall survival (OR 0.69; CI 0.60–0.81), decreased disease free survival (OR 0.51; CI 0.36–0.73) and cancer specific survival (OR 0.71; CI 0.54–0.94). Distant recurrence (OR 1.10; CI 0.89–1.37) and overall recurrence (OR 1.33; CI 0.64–2.76) were not significantly different between the two groups.

Conclusions

AL may negatively impact cancer-specific outcomes after curative rectal cancer surgery and could be considered an independent negative prognostic factor.

Verbände und Cremes gegen Dekubitus: „Wir wissen nicht, was sie bringen!“

Die Datenlage zur Wirksamkeit von Verbänden oder topischen Mitteln zur Prävention von Druckgeschwüren sei schlecht, so die Verfasser einer aktuellen Cochrane-Studie. Letztlich bleibe es unsicher, ob solche Maßnahmen den Betroffenen nutzen oder schaden.

Nackenschmerzen nach Bandscheibenvorfall: Muskeltraining hilft!

Bei hartnäckigen Schmerzen aufgrund einer zervikalen Radikulopathie schlägt ein Team der Universität Istanbul vor, lokale Steroidinjektionen mit einem speziellen Trainingsprogramm zur Stabilisierung der Nackenmuskulatur zu kombinieren.

US-Team empfiehlt Gastropexie nach Hiatushernien-Op.

Zur Vermeidung von Rezidiven nach Reparatur einer paraösophagealen Hiatushernie sollte einem US-Team zufolge der Magen bei der Op. routinemäßig an der Bauchwand fixiert werden. Das Ergebnis einer randomisierten Studie scheint dafür zu sprechen.

Mit Lidocain kommt der Darm nicht schneller in Schwung

Verzögertes Wiederanspringen der Darmfunktion ist ein Hauptfaktor dafür, wenn Patientinnen und Patienten nach einer Kolonresektion länger als geplant im Krankenhaus bleiben müssen. Ob man diesem Problem mit Lidocain vorbeugen kann, war Thema einer Studie.
