Prostate surgery has seen several advances in recent times.
is a common procedure where the prostate is removed along with its neighboring tissues. Depending on the site of the incision, the surgery may be radical retropubic prostatectomy, where the incision is made in the lower abdomen, or radical perineal prostatectomy, where the incision is made in the perineal region. Transurethral resection of prostate
(TURP) is also sometimes done to relieve urinary symptoms. In this procedure, the prostate is cut through an instrument that is introduced into the urethra. It is more commonly done for benign prostate hyperplasia (BPH).
‘The human touch seems to be as important as robots when it comes to surgery for prostate cancer.’
In contrast to open surgery, laparoscopic or keyhole surgery requires more surgical skill and experience. The recovery time is however faster with this type of surgery. The robotic da Vinci system is an advancement in the field of laparoscopic surgery. It must be clarified that a robotic surgery
does not mean that a robot does the surgery all by itself. The surgeon guides the robotic arms in such a way that the surgery can be carried out with precision. Such a surgery is more appropriately called robot-assisted surgery.
Research team compared the
surgical results and outcomes of robotic radical prostatectomy versus open
radical retropubic prostatectomy.
The patients included in the study were men of 35 to 70 years of age, had localized prostate cancer
and an estimated life expectancy of 10 years or more. In the study 157 patients underwent laparoscopic robotic radical prostatectomy
while 151 underwent open radical retropubic prostatectomy.
Side effects of prostate surgery include urinary
incontinence and sexual dysfunction. Based
on a questionnaire taken from 121 patients who underwent open surgery and 131
patients who underwent robotic surgery, it was found that the urinary function
was similar in the two groups, at 6 weeks or 12 weeks after surgery.
The effects of the two surgeries on sexual functions were
also not significantly different.
during and after the operation were slightly higher in the open radical
prostatectomy group as compared to the robotic surgery group. Intraoperative
complications occurred in 9% and 4% in the radical retropubic prostatectomy
group and the robot-assisted laparoscopic prostatectomy group, while
postoperative complications were noted in the 8% and 2% patients, respectively.
Further data which will be obtained after 24 months after
the surgeries will provide further insight into the possible difference or lack
of difference between the two procedures.
The study concluded that when
choosing this operation, it is more important for the patients to get the
surgery done from an experienced surgeon rather than worrying about the type of
technique used to remove the cancerous prostate gland.
Laparoscopic robotic surgery in this study did
not show any advantage over open prostatectomy when an experienced surgeon was
performing the surgery.
