Week One: So it begins
I can guess with this post the first week has ended, and
well it has been pretty interesting so far. My clinical mentor is Dr. Jim Hu
M.D., and I have learned a lot about some of the more minute details involving prostate
cancer cases. I’ve known about the screening processes such as measuring PSA
levels and the digital rectal exam, but the steps beyond that I’ve for the most
part ignored. However, being immersed this past week in the hospital has
allowed me to see some of these other steps. In particular, I have seen and
learned more about the process of MRI Ultrasound Fusion Guided Biopsy. For this
procedure, patients undergo an MRI scan to segment the prostate and help identify
regions of suspicion. The scan is then used to construct a 3D rendering of the
prostate with suspicious areas identified. Using this data, the oncologist then
uses an ultrasound probe to guide the biopsy needle to both the suspicious
areas and the routine systematic biopsy sites using the MRI scan as a kind of
roadmap. Seeing this and learning more about it was a new experience with some
minor discomfort in seeing that biopsy needle (yea I am not that great with
needles). However, seeing this precision and how much goes into getting
accurate locations for the biopsy samples was exciting and something I had
never thought about before.
Beyond
understanding more about fusion biopsy, I have also watched a laparoscopic proctectomy
utilizing the Da Vinci Surgical System (see below). Seeing the robot in action
was something I had always been excited to see, but I did not expect to see it
in my first week here. The surgery itself involved using only a few small
incisions to allow instruments and the camera to enter the body cavity, and
then careful maneuvering to move the bladder and remove the prostate. Once the
prostate was removed, the urethra and the bladder were reconnected followed by
the incisions closed. While I make this sound simple, there were a lot of tiny
details that make this procedure much more complicated to show the expertise
required for it.
