Chirurgische Konzepte und Strategien bei Kolonadenomen und Polyposissyndromen

Abstract

Surgical Approach and Strategies in Colon Adenomas and Polyposis Syndromes Development of modern, minimally invasive methods for diagnosis and treatment in the field of colorectal tumours enables an effective surveillance for persons at high risk as well as a distinct cancer prevention by endoscopic, transanal or TEM removal of colorectal adenomas. Introduction of laparoscopic techniques in the resection of colorectal tumours could entail, after evaluation of preliminary results, a decreased duration of hospitalisation and procedure-associated morbidity in patients with the same prognosis. The very high risk for development of colorectal tumours as well as for some extracolonic neoplasia is typical for familial colorectal cancer syndromes. This concerns hereditary nonpolyposis colorectal cancer (HNPCC) syndrome, familial polyposis coli, and the infrequent forms like Peutz-Jeghers syndrome and juvenile polyposis. Molecular diagnostics has the power to identify carriers and noncarriers of a mutated gene in these families and therefore may permit clear-cut decisions regarding inclusion in special surveillance programmes, which is recommended for all persons at risk from affected families. Concerning the surgical approach in patients with hereditary colorectal cancer, well-accepted routine procedures like restorative proctocolectomy in familiar polyposis patients have already been established; in other forms like HNPCC the best surgical modality is still under discussion. Remarkable progress in the prevention of colorectal tumours could be expected from chemoprevention trials in the next years.

Laparoskopische kolorektale Resektionen bei benignen Polypen

“…chirurgisch assistierte Verfahren dar [13]. Laparoskopische Operationstechniken zur Behandlung von benignen kolorektalen Tumoren haben hierbei in den letzten 10 Jahren einen festen Stellenwert erlangt [14]. Durch die Laparoskopie ist es möglich die Vorteile der minimalen Invasivität mit der Forderung nach suffizienter chirurgischer Resektion zu verbinden.…”
