Prostate Cancer Clinical Trial
Laparoscopic TAP Block During Robotic Assisted Laparoscopic Radical Prostatectomy for Improvement in Postoperative Pain
Determine the impact of a laparoscopic-guided transversus abdominis plane (TAP) block timing (at initiation or conclusion of procedure) on the postoperative pain experience in patients following robot assisted laparoscopic radical prostatectomy (RALP).
TAP block involves the use of a local anesthetic agent injected between the internal oblique and transversus abdominis muscles for the goal of pain relief. Often times these are performed under ultrasound guidance by the anesthesiology team preoperatively. The idea behind this is to provide a neurologic block to the sensory nerve fibers supplying the anterior abdominal wall, between the internal oblique and transversus abdominis muscles. More recently, this technique has been investigated in the setting of robot-assisted laparoscopic radical prostatectomy (RALP) with promising results. There is a lack of data comparing the benefits of the timing of TAP block, and whether performing this at the initiation versus conclusion of the case provides superior results
This is a prospective, randomized controlled trial of subjects undergoing early versus late TAP block for the management of postoperative pain following RALP. Subjects will be recruited through physician referral from private Urology offices. Potential subjects (patients scheduled for RALP procedure) will be approached by the study doctor prior to surgery, either in the study doctor's office or in the pre-operative area.
Subjects who meet all the eligibility criteria will be enrolled in the study and randomized (1:1) to receive early or late surgeon performed laparoscopic TAP block. Each patient will only receive one treatment (TAP block) either at the initiation or conclusion of his procedure.
For treatment delivery, subjects will receive 60 mL of 0.25 percent ropivacaine with 4 mg of dexamethasone either at the initiation of the procedure (immediately following placement of the robotic / laparoscopic camera port) or at the conclusion of the procedure (immediately proceeding removal of the robotic / laparoscopic camera port). Study doctors will use laparoscopic / robotic camera visual aid to confirm positioning between the internal oblique and transversus abdominis muscles for the goal of pain relief.
