Abstract

Background The role of simulation for training in procedures such as laparoscopic incisional hernia repair (LIHR) is unknown. The purpose of this study was to determine whether performance in simulated LIHR correlates with operating room (OR) performance. Methods Subjects performed LIHR in the University of Maryland Surgical Abdominal Wall (SAW) simulator and the OR. Trained observers used a LIHR-specific global rating scale (Global Operative Assessment of Laparoscopic SkillsIncisional Hernia) to assess performance. Global Operative Assessment of Laparoscopic SkillsIncisional Hernia includes 7 domains (trocar placement, adhesiolysis, mesh sizing, mesh positioning, mesh fixation, knowledge and autonomy in instrument use, and overall competence). The correlation between simulator and OR performance was assessed using the Pearson coefficient. Results Fourteen surgeons from 2 surgical departments participated. Experienced surgeons (n = 9) were defined as attending surgeons and minimally invasive surgury (MIS) fellows, and novice surgeons (n = 5) were general surgery residents (postgraduate years 35). The correlation between performance in the OR and the simulator for the entire group was .87 (95% confidence interval, .63.96; P < .001). Conclusions There was an excellent correlation between LIHR performance in the simulator and clinical LIHR. This suggests that performance in the SAW simulator may predict performance in the operating room.
