Patients may feel significant pain at the surgery site after they wake up from the surgery.
Usually pain is managed in the ward by giving strong pain medication that may slow down your
mobilization and recovery process. Some recent work in other countries has shown that if
investigator give patients an injection at the end of the operation, patients have less need
for pain medication when they wake up. If investigator find that is also true in our
population, then we can use this method as routine step after this operation to improve pain
management and early mobilization of our patients
