Objective
To compare laparoscopic versus open surgery for rectal cancer and analyse the results of the multidisciplinary audited project on total mesorectal excision conducted in Spain.
Background
The safety and therapeutic efficiency of laparoscopic surgery for rectal cancer are controversial due to the technical difficulties it involves. A deviation from the oncological principles of mesorectal excision would mean a potential increase in local recurrence and shorter survival.
Methods
This prospective non-randomised multicentre study includes 4,970 patients with rectal cancer. The study compares perioperative, postoperative, anatomicopathological and survival variables.
Results
Five hundred and sixty five patients were excluded. Of the remaining 4,405, 3,018 (68.51 %) had open surgery (OS) and 1,387 (31.49 %) laparoscopic surgery (LS). The rate of anterior resections was higher in the LS group. The rate of intraoperative tumour perforation, number of red blood cell concentrates transfused and length of hospital stay were greater in the OS group, whereas surgical time was longer in the LS group. The incidence of complications was 45.6 % in the OS group and 38.3 % in the LS group. Involvement of the circumferential and distal margin, as well as unsatisfactory and partially satisfactory quality of the mesorectum, were greater in the OS group. There were no differences for local recurrence and survival rates.
Conclusions
According to these results, laparoscopic surgery is the best option for the surgical treatment of rectal cancer, with similar rates of local recurrence and survival, although there are oncological indicators in this study to suggest that these results can be improved with laparoscopic surgery.
