(Note:
many of the operator, incision, and port site positions to
be mentioned are what have worked for us. Others may find
modifications more comfortable for them, specifically with
respect to the ultimate hand-assist device placement. In
our description, we have chosen to introduce our right
hand for hand-assistance and use our left hand to handle
laparoscopic instruments. Our
team involves both a left-hand and right-hand dominant
surgeon, and we have both operated comfortably through the
set up provided. Conceptually, a right- handed surgeon may
prefer to introduce his/her non-dominant hand through a
mirror image set up while operating from the patient’s
left side. Either should allow good exposure and
functional assistance. Either would have the potential for
conversion if necessary. Also of note, we have
experimented with and rejected a vertical, midline,
epigastric incision for various reasons including not
offering advantageous triangulation to the stomach and
because it tends to block the camera view).
With
the hand introduced, a combination of visual and tactile
exploration may be carried out. Laparoscopic
ultrasound is a useful adjunct to the initial exploration
in cases of suspected malignancy. Initial
port placement consists of a 5 mm trocar in the epigastric
region. This port will be used for dissection and/or left
lobe retraction. A 12 mm port is placed several
centimeters below the right subcostal margin in the
anterior axillary line. It will also be used for
dissection and for introduction of linear staplers. For
safety, the hand should be retracted into the sleeve above
the base retractor whenever introducing trocars.
