Introduction: Digestive surgery is the second cause of death in Italy. It has undergone significant changes in the last decade both in terms of technique and thought. all this resulted in a significant reduction in complications, with a significant increase in positive results, and its diffusion in almost all national hospital centers. Materials and Methods: From January 2010 to December 2017 consulted the database of the AOU Polyclinic University of Catania were observed in the Department of Medical and Surgical Sciences II n 93 cases of colon neoplasia with headquarters: in the blind 3 n cases (3.5%), colon ds n 39 cases (41.5%), transverse colon n 4 cases (4.2%), colon sn n 41 cases (44.6%), sigma n 6 cases (6.2%). The patients selected for this analysis had a mean age of 72 years (range 74-70). Results: Operations with preservation of the sphincters (fig 2) represent 95% of the cases (n 112 cases) and of these in n 24 cases (21%) there was an exitus in the postoperative data on the accuracy of the diagnostic tests for images ranging from 57 to 81% due to the ineffectiveness sometimes in highlighting the parietal infiltration due to the impossibility of verifying the layers of which the viscera is composed the most reliable examination in the I and II TND tumor of the neoplasm was the echendoscopy especially in the evaluation of by parietal diffusion. secondary lesions the limits of the diagnostic methods for imaging were lesions smaller than 1.5 cm unique small and vascularized Discussion :For this type of surgery are used diagnostic procedures of fundamental importance in the staging of the tumor with a careful evaluation of the most reliable methods of which the actual utility was or subject of numerous studies. the effectiveness of a diagnostic method remains linked to the stage of the neoplasm as it is possible to highlight the extent of the disease, its lymphatic diffusion, the parietal and by parietal invasion and the presence of secondary lesions. The limits of diagnostic imaging have been identified in lesions smaller than 1.5 cm in which PET detects the site and the metabolic state but the origin of the lesion remains of dubious interpretation. in the preparation for video-assisted surgery, patients performed the same procedures as open surgery, an assessment of risk factors is not complete, although we feel we are asserting in a first evaluation that we are seeing a reduction in the length of hospital stay, with better aesthetic and functional results, the abolition of the parietal trauma and the possibility of avoiding exploratory laparoscopies. Although like every surgical practice it too is burdened by complications related to a lengthening of the operating times, that in the introduction of the needle of verres, or of the trocars. Conclusions. The use of protocols that prevent risk factors have proven effective in reducing the complications that this surgery involves. The incidence of risk factors in this surgery are high and affect the results due to the presence of dehiscences and complications within 30 days from the treatment, very often determining the therapeutic failure
