Resumen

BANNURA C., Guillermo et al. Radical surgery for locally advanced rectal cáncer. comparative analysis of laparoscopic surgery with open surgery. Rev. cir. [online]. 2020, vol.72, n.6, pp.559-566. ISSN 2452-4557.  http://dx.doi.org/10.35687/s2452-45492020006731.

Introduction:

Total mesorectal excison and preoperative radiotherapy are important components of multimodal treatment in patients with a low locally advanced rectal cancer. Short-term results of laparoscopic surgery has proven to be safe but oncological results are unclear.

Aim:

To compare short-term and oncologic outcomes of laparoscopic and open resection of locally advanced rectal cancer operated on in the same period.

Materials and Method:

A total of 327 patientes with rectal cancer treated by open and laparoscopic curative surgery were retrospectively reviewed. Long-term follow up was compared using Kaplan-Meier curves and survival data were tested by log rank test.

Results:

Demographic data, levels of carcinoembryonaric antigen, perioperative morbidity and pathologic stages were similar in both groups, except for less inhospital time in laparoscopic group (p = 0.007). Over 90% of middle and low tumors recived preoperative radiotherapy. Local recurrence and overall survival shows no difference between both groups. Low and middle rectal cancer showed worst prognosis than tumors of the high rectum, no matter of type of surgery (p = 0.007).

Conclusions:

Laparoscopic surgery is non-inferior to open resection for pathological and oncological outcomes. It's not convenient to include on trials lesions located in the high rectum, usually treated with primary surgery as colon cancer.
