Study Summary
New minimally invasive surgical treatments are often outpatient procedures with low complication rates, promising fast recovery. The traditional physician-reported outcomes such as complication rates, blood loss, and hospital stay are not useful to guide treatment recommendations for one or the other minimally invasive procedure. This study aims to apply patient-reported outcomes developed within the NIH framework for cancer research and chronic disease treatment to the comparative effectiveness research in minimally invasive procedures for benign disease.
Primary Outcome
The investigators will utilize the Patient-Reported Outcomes from the VAS to measure changes from Baseline to day 1 post OP. A 15-mm difference on a 100-mm visual analog scale with a standard deviation of 25 mm at any time point will constitute a clinically relevant difference.
Interventions
- PROCEDURE Single-port cholecystectomy
- PROCEDURE Four-port laparoscopic cholecystectomy
