[Colorectal carcinoma. Minimally invasive surgery under quality aspects--limitations].

摘要: Owing to a lack of long-term survival in prospective randomized studies controversy continues surround the use laparoscopic resection cases colorectal carcinoma. However short-term and recurrence rate seem be similar conventional procedures. Mortality morbidity rates following surgery equal surgery. Oncological problems associated with curative intent include inadequate radicality, incorrect surgical technique, failure observe technical and/or oncological limitations applicable certain tumor sites. Carcinomas right left hemicolon, colon sigmoideum lower rectum without possibility continence preservation can safely treated by laparoscopy. All other locations, tumors size greater than 8 cm involving surrounding tissue are technically demanding difficult laparoscopically criteria. The incidence pathogenesis trocar site metastases unknown. Surgical concepts avoid these sequelae not established.
