Laparoscopic Donor Nephrectomy | Device: Percuvance™ Percutaneous Surgical System | Not Applicable |
Purpose:
Prior investigators have created methods to perform laparoscopic surgeries using smaller instruments and ports in an attempt to improve cosmesis and postoperative pain. However, These methods may be limited by the requirement for smaller instruments with decreased functionality or by the loss of instrument triangulation. We have previously published a study regarding the use of a new surgical paradigm (percutaneous externally assembled laparoscopy, or PEAL) in porcine and cadaveric models in order to allow laparoscopic surgery to take place with improved cosmesis and decreased pain while still allowing the use of larger instruments and maintaining instrument triangulation. We now seek to study the use of these instruments in the human patients undergoing laparoscopic urologic surgery.
The procedures include:
Hundred subjects will be recruited for the study with an expected attrition rate of 10%. Sample size has been minimized, but is necessary for statistical power and conclusions. Subjects will be male and female 18 years or older, of all ethnicities, denominations or other social/economical variations. All participants will speak English fluently in order for consent to be performed properly. Baseline pain score will be calculated through a questionnaire in at the urology clinic
This will be a single-arm prospective internally-controlled study. Patients will undergo percutaneous externally-assembled laparoscopic urologic surgery where one or more 3 mm instruments are added or substituted for conventional 5 or 10 mm trocars. Multiple outcome measures (endpoints) will be measured including time to first opioid use, total inpatient opioid dosage, patient ranking of painfulness of each port site, duration of ileus, time to ambulation, length of hospital stay, presence of any intraoperative or postoperative complications, operating time, estimated blood loss, and other routine parameters collected in a prospective surgical study.
