A Randomized Controlled Study to Evaluate the Impact of Instrument and Laparoscope Length on Performance and Learning Curve in Single-Incision Laparoscopic Surgery
2015
Introduction. The proximity of instrumentation in single-incision laparoscopic surgery (SILS) creates ergonomic challenges. An innovative method to reduce external collisions between instruments and handles is to use instruments of different lengths. This study evaluated the impact of instrument and laparoscope length on simulated SILS performance. Methods. Performance was assessed using peg transfer (PEG) and pattern cutting (CUT) tasks from the Fundamentals of Laparoscopic Surgery (FLS) curriculum. Following baseline testing, surgeons were randomized into 3 trial arms: Control—standard length instruments and standard length laparoscope; group 1—one long instrument, one standard length instrument and standard length laparoscope; and group 2—standard length instruments and long laparoscope. Two phases were undertaken using a validated SILS-modified FLS box trainer: phase 1—25 repetitions of PEG and phase 2—5 repetitions of CUT. FLS scoring parameters measured performance and the Imperial College Surgical ...
