Abstract

Background: Interest in laparoendoscopic single-site surgery (LESS) is growing rapidly among surgeons. This study aimed to characterize current surgeon impressions about LESS and to determine the relative difficulty of performing a simulated LESS task using a multiport access device. Methods: This study was conducted at the 2009 Society of Gastrointestinal Endoscopic Surgeons (SAGES) Learning Center. The 56 study participants were asked to complete pre- and post-test questionnaires regarding their level of training, prior clinical experience, and opinions about LESS. Technical skill performance was evaluated using the standardized fundamentals of laparoscopic surgery Peg Transfer task scored according to time and error metrics. The participants completed three repetitions: conventional laparoscopy (LAP), LESS with nonarticulated instruments (LESS Straight), and LESS with articulated instruments (LESS Articulating). Results: Complete data were collected for 45 (80%) of the 56 participants, which included 27 practicing surgeons, nine minimally invasive surgery (MIS) fellows, seven residents, and two allied health professionals. Five surgeons (LESS experienced) had managed at least one LESS case in the preceding 6 months. Participants rated their comfort with LESS as 2.0 ± 1.2 (5-point scale, 1 = very uncomfortable). Compared with conventional laparoscopy, the participants indicated that LESS had 97% better cosmesis, 25% decreased postoperative pain, 18% faster recovery, 97% more demanding, 73% increased rate of complications, and 82% anticipated wide adoption. They all indicated a readiness to offer LESS to their patients if appropriately trained. Peg Transfer performance was significantly worse for LESS than for LAP (40-65% performance decline), and for LESS Articulating than for LESS Straight (44% performance decline). Construct validity for the LESS simulated tasks was supported because the LESS-experienced scores were significantly better than the LESS-nonexpert scores. Conclusion: Despite the increased technical difficulty associated with the LESS approach, surgeons are enthusiastic about offering these techniques and seeking additional training. Robust simulation-based methods that foster skill acquisition through repetitive practice and verification of proficiency are needed such that safe adoption may be fostered.
