Background. Undoubtedly, robotic systems have largely penetrated the surgical feld. For any new operative approach to become an
accepted alternative to conventional methods, it must be proved safe and result in comparable outcomes. Te purpose of this study
is to compare the short-term operative as well as oncologic outcomes of robotic-assisted and laparoscopic rectal cancer resections.
Methods. Tis is a prospective randomized clinical trial conducted on patients with rectal cancer undergoing either robotic-assisted
or laparoscopic surgery from April 2015 till February 2017. Patients’ demographics, operative parameters, and short-term clinical
and oncological outcomes were analyzed. Results. Fify-seven patients underwent permuted block randomization. Of these patients,
28 were assigned to undergo robotic-assisted rectal surgery and 29 to laparoscopic rectal surgery. Afer exclusion of 12 patients
following randomization, 45 patients were included in the analysis. No signifcant diferences exist between both groups in terms of
age, gender, BMI, ASA score, clinical stage, and rate of receiving upfront chemoradiation. Estimated blood loss was evidently lower
in the robotic than in the laparoscopic group (median: 200 versus 325 ml, p= 0.050). A signifcantly more distal margin is achieved
in the robotic than in the laparoscopic group (median: 2.8 versus 1.8, p< 0.001). Although the circumferential radial margin (CRM)
was complete in 18 patients (85.7%) in the robotic group in contrast to 15 patients (62.5%) in the laparoscopic group, it did not
difer statistically (p=0.079). Te overall postoperative complication rates were similar between the two groups. Conclusion. To our
knowledge, this is the frst prospective randomized trial of robotic rectal surgery in the Middle East and Northern Africa region.
Our early experience indicates that robotic rectal surgery is a feasible and safe procedure. It is not inferior to standard laparoscopy
in terms of oncologic radicality and surgical complications. Organization number is IORG0003381. IRB number is IRB00004025.
1. Background
Over the past two decades, rectal cancer management under-
went an immense wave of change from various perspectives.
Tere was a smart shif from open to minimally invasive and
robotic techniques, a worldwide application of neoadjuvant
multimodal chemoradiation therapy for locally advanced
stage disease, as well as optimization of surgical technique
with nerve preservation together with the introduction of
total mesorectal excision (TME) which were all largely
happening in the preceding 10–15 years. Te frst colorectal
laparoscopic procedure was operated upon by Jacobs in 1991
[1]. A decade later, in 2001, the robotic system was introduced
to colorectal surgery [2].
To date, laparoscopic surgery has been acknowledged
as a safe and efective modality of rectal cancer surgery.
However, a randomized controlled multicenter trial has
recently suggested that the use of laparoscopic surgery in
T3/T4 tumors may result in incomplete resection, afecting
the oncological outcome in this group of patients [3]. Te
