The most voluminous synchronous cancer is called first primitive or index cancer. The aim of this work is to describe our experience of minimally invasive approach in patients with synchronous colorectal neoplasias. Since January 2001 till December 2009 557 patients underwent colectomy for colorectal cancer at the Department of General and Emergency Surgery of the University of Perugia 128 were right colon cancers 195 were left colon cancers while 234 patients were affected by rectal cancers. We performed 224 laparoscopic colectomies 112 right 67 left colectomies and 45 anterior resections of rectum 91 Transanal Endoscopic Microsurgical Excisions TEM and 53 Trans Anal Excisions TAE . In the same observation period 6 patients 4 males and 2 females were diagnosed with synchronous colorectal neoplasias. Minimal invasive treatment of colorectal cancer offers the opportunity to treat two different neoplastic lesions at the same time with a shorter post-operative hospitalization and minor complications. According to our experience laparoscopy and TEM may ease the treatment of synchronous diseases with a lower morbidity rate. Introduction Synchronous colorectal neoplasias defined as 2 or more primary tumors identified in the same patient and at the same time are caused by common genetic and environmental factors 1 .
