This will be a single-arm prospective internally-controlled study. Patients will undergo percutaneous externally-assembled laparoscopic surgery where one or more 3 mm instruments are added or substituted for conventional 5 or 10 mm trocars.

Official Title

A Prospective Study of Port Site Pain Following Percutaneous Externally-Assembled Laparoscopic Urologic Surgery

Brief Summary

This will be a single-arm prospective internally-controlled study. Patients will undergo <br /> percutaneous externally-assembled laparoscopic surgery where one or more 3 mm instruments are <br /> added or substituted for conventional 5 or 10 mm trocars.

Detailed Description

The investigators 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. The investigators now seek to study the use of these instruments in the human
patients undergoing laparoscopic urologic surgery.

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.
