OBJECTIVE
To report the change in complication rates after the identification
and modification of technique to reduce their incidence during
robot-assisted radical prostatectomy (RARP).
METHODS
This study retrospectively reviewed 1000 consecutive patients who
underwent RARP from June 2002 to June 2011. A number of technical changes
were made after complications were noted and changes in technique were
documented. The Fisher exact test and multivariate analysis were used for
comparison of techniques, and values of P <.05 were
considered significant.
RESULTS
The overall rate of major and minor complications was 10.8%
(108 of 1000). The complication rates of lymphoceles (0.4%), ileus
(0.4%), and wound infection (0.4%) were low and did not
require technical changes. There were no significant changes in rates of
femoral nerve palsies, rectal injuries, or bladder neck contractures. There
was statistically significant change in corneal abrasions
(P = .03), fossa navicularis strictures
(P = .03), and camera-site hernias (P
<.001) after a directed intervention adjusted for age, body mass
index, and learning curve. Clavien 3 and 4 complications all significantly
decreased to ≤0.6%, with the most occurring in the first 200
cases.
CONCLUSION
Identification and correction of perioperative complications in
patients undergoing robotic prostatectomy has decreased the incidence of
major and minor complications adjusted for learning curve. The conscientious
monitoring of adverse events can provide targeted change in technique to
decrease complications and provide information to those early in learning
robotic-assisted radical prostatectomy.
