Coloproctology Aims and scope

Abstract

We describe 10 patients with villous tumors of the rectum. Seven tumors showed severe dysplasia but only one invasion of the muscularis propria of the bowel wall. All patients underwent a sphincter-conserving operation. There was one local recurrence which was treated by further local excision. One patient died of other causes, but the remainders recovered.

Villous tumors of the rectum, even those showing severe dysplasia, can be adequately treated by local excision because they are adenomas. However, anterior resection is indicated when the tumor is too large for local excision, is located in the upper rectum, or when invasive cancer cannot be ruled out.

Zusammenfassung

Es werden zehn Patienten mit villösen Rektutumoren beschrieben. Sieben Tumoren zeigten eine schwere Dysplasie, aber nur einer eine Invasion in die Lamina muscularis propria der Darmwand. Alle Patienten wurden einer sphinktererhaltenden Operation unterzogen. Es trat ein Lokalrezidiv auf, das mit einer weiteren lokalen Exzision behandelt wurde. Ein Patient starb aus anderen Gründen, die übrigen erholten sich.

Villöse Tumoren des Rektums, auch solche mit schweren Dysplasien, können angemessen mit lokalen Exzisionen behandelt werden, weil es sich bei ihnen um Adenome handelt. Trotzdem ist die vordere Resektion indiziert, wenn der Tumor zu groß für eine lokale Exzision ist, wenn er im oberen Rektum lokalisiert ist oder wenn ein invasiv wachsendes Karzimon nicht ausgeschlossen werden kann.
