A preliminary study of surgeon stress measures during randomized controlled trials of 4-port vs. single incision cholecystectomies

With various minimally invasive approaches in the field of surgery and new techniques entering rapidly, it is important to evaluate the effectiveness of these different practices. Information about the impact on both patient and provider can be gained through research investigations. Since the workload placed on the surgeon may influence patient outcomes, this study measured levels of stress and fatigue for the surgeon participating in an NIH randomized control trial of single incision versus 4-port laparoscopic cholecystectomy. Through the administration of the SURG-TLX for 22 Single-Incision Laparoscopic Cholecystectomies and 24 4-port cholecystectomies, physical workload was the only measure statistically different between 4-port and SILC (P=0.028). There was a significant difference in the duration (P=0.029) based on the procedure that was completed. Mental stress was highly correlated to many of the variables in the Surg-TLX and duration, degree of difficulty, and complexity were all highly correlated. This research shows how the SILC procedure can cause more stress on the surgeon. When the situation is combined with longer surgeries, higher complexity, and a higher degree of difficulty, the patient outcomes may be at risk.
