Effect of Preincisional Local Analgesia on Post-Operative Pain in 10-12mm Lateral Port Sites
This study will help to answer the question, "Does injecting local anesthetic before
laparoscopic instrument ports are placed decrease pain after surgery?" Patients
participating will be randomly assigned to receive local anesthetic or saline injection at
the site of a laparoscopic instrument port as part of their planned surgery. After surgery
at 4 and 24 hours the patient will be asked to rate their pain on a simple chart.

The literature is divided on the efficacy of preincisional local analgesia injections at
laparoscopic port sites to decrease post operative pain. One reason for this lack of a clear
conclusion is the fact that prior studies included small and large port sizes. Many small
port sites have little pain associated with them so showing a reduction with medicine is
statistically difficult. The investigators have noted that larger, lateral port sites which
require fascial closure are the sites that patients consistently note pain at. Our protocol
will include the use of 0.25% marcaine injections at all the surgical ports other than the
large lateral port used for gynecologic laparoscopy. Patients would then be randomized and
surgeons would be blinded as to which patients receive the marcaine or a saline injection at
the large lateral port site. Visual analog pain scales will be assessed at 4 and 24 hours
after surgery. An additional two arms have been added to include 50 patients randomized to
0.25% marcaine or saline injection just prior to incisional closure in the absence of any
preincisional intervention.
