Background: Minimally invasive techniques have revolutionized
the field of general surgery over the few last decades. Despite its
advantages, in complex procedures such as rectal surgery,
laparoscopy has not achieved a high penetration rate because of
its steep learning curve, its relatively high conversion rate and
technical challenges. The aim of this study was to present a
single center experience with robotic surgery for rectal cancer
focusing mainly on early and mid-term postoperative outcome.
Methods: A series of 100 consecutive patients who underwent
robotic rectal surgery between January 2008 and June
2012 was analyzed retrospectively in terms of demographics, pathological data, surgical and oncological outcomes.
Results: Seventy-seven patients underwent robotic sphinctersaving
resection, and 23 patients underwent robotic abdominoperineal
resection. There were 4 conversions. The median
operative time for sphincter-saving procedures was 180 min.
The median time for robotic abdominoperineal resection was
160 min. The median distal resection margin of the operative
specimen was 3 cm. The median number of retrieved lymph
nodes was 14. The median hospital stay was 10 days. Inhospital
mortality was nil. The overall morbidity was 30%.
Four patients presented transitory postoperative urinary
dysfunction. Severe erectile dysfunction was reported by 3
patients. The median length of follow-up was 24 months. The
3-year overall survival rate was 90%.
Conclusions: Robotic surgery is advantageous for both
surgeons (in that it facilitates dissection in a narrow pelvis) and
patients (in that it affords a very good quality of life via the
preservation of sexual and urinary function in the vast
majority of patients and it has low morbidity and good midterm
oncological outcomes). In rectal cancer surgery, the
robotic approach is a promising alternative and is expected to
overcome the low penetration rate of laparoscopy in this field.
