Abstract

Introduction: Laparoscopic surgery of the colon has been performed since the early nineties of the past century. Despite its advantages of less postoperative pain, faster recovery of intestinal and respiratory function among others, its acceptance has not been the same as with other laparoscopic procedures. In oncologic surgery particularly, the main cause of non-acceptance has been the fear of not respecting the oncologic criteria and the reports on port site metastases in the abdominal wall.
Objective: To determine patient survival after laparoscopic colorectal resections.
Material and methods: A descriptive, retrospective and longitudinal study was carried out at the Centro Nacional de Cirugía de Mínimo Acceso (CNCMA-NCMIS) between January 2005 and December 2015. The variables studied were age, gender, reason for surgery, surgical technique, mortality, overall survival.
Results: When comparing the survival curves according to the location of the tumor, it was found that those who had undergone surgery for a rectal tumor had a significantly lower survival during complete follow-up than patients with tumors in the rest of the sites (p=0,032). Significant differences were also found in the survival curves regarding the stage of the disease; stage IV patients showed the worst survival during the follow-up of this series.
Conclusions: Survival in our study, with the limitations given by a retrospective analysis, in patients who had surgery for colorectal cancer with minimally invasive techniques at five and ten years was 70,9% and 66,8% respectively, an appropriate rate and similar to that described in scientific medical literature.
