After Laparoscopic surgery most patients experience some form of mild to moderate pain. The
current standard of care is to treat this pain with local anesthetics (numbing medication,
that deadens the nerve endings) to the small surgical incisions (cuts) and narcotic systemic
analgesics (medication injected into your vein to control pain such as morphine).
Although this treatment improves pain symptoms it is not perfect. Firstly, complete pain
control is rarely achieved and secondly, narcotics (such as morphine) often have many side
effects including nausea, vomiting, sedation (sleepiness), constipation and abdominal upset.
All of these issues make recovery less comfortable and delays return to full function (work,
school and other activities of daily life).
A new FDA approved device is now available that offers the benefits of long term anesthesia
without the side effects of narcotics. It consists of a pump that continuously infuses local
anesthesia into and around the surgical site. This pump is placed during your operation. You
then carry a tennis ball sized container made of soft plastic in a pouch which drips numbing
medicine around your wounds for 2 days continuously.
The purpose of this study is to see if this pump improves postoperative pain, decreases the
need for narcotic pain medicine and allows people to return to their activities earlier.

The procedure of the current study is to randomly assign patients undergoing minimally
invasive surgeries (laparoscopic cholecystectomies and laparoscopic Lap-Banding procedures)
to one of two groups. Both groups will have the standard surgical procedure performed and
then at the completion will have the on-Q system placed in a subdiaphragmatic (within the
abdomen) location. Half of the study group will have bupivicaine, a numbing medicine in the
pump while the other half will have sterile saline in their pump. Neither the patient nor the
surgeon will be aware of which group any particular patient is in, this is a process known as
"blinding" and improves the reliability of the results. All patients will receive the
standard locally infiltrated trocar site local anesthetic and either a prescription for
Vicodin for ambulatory patients or morphine injected into their vein for patients staying in
the hospital.
All patients will then be asked at preset intervals their level of pain the presence of
nausea and their need for Vicodin or morphine. Ambulatory patients will be reached by phone
for answers to these questions. All patients will have their pain controlled in the usual and
standard way at all times. The On-Q pump will be removed at 48hours.
The results will then be statistically reviewed to see if the On-Q pumps were of benefit.
