Background: Laparoscopic suturing is required to develop competency in advanced laparoscopy. Methods: Manuals detailing laparoscopic suturing were give to 17 Surgery residents. One week later they performed a suture on a training model. Time (s), accuracy (mm), and knot strength (1b) were recorded. The residents were blindly randomized to intervention (n = 9) and control (n = 8) groups. The intervention residents attended a 60-min course with lecture, video, and individual proctoring. Two weeks later they performed a stitch with standard laparoscopic instruments and a stitch with a suturing assist device. Statistical analysis included a Wilcoxon rank-sum test. Results: The intervention residents decreased their suturing time from the first to the second stitich (732.4-257.6s), the control and residents decreased their time from 500.2 s to 421.8 s. The time required to perform the second stitch showed no significant difference between the two groups (p = 0.46), but the difference in reduced time between the first and second stitch was significant (p = 0.001), Using the suturing assist device for the third suture, the intervention and control groups both decreased their times significantly. The control residents performed almost as quickly as the intervention residents with the suturing; device (p = 0.11). Accuracy and knot strength were not different in any test. Conclusions: Residents can improve suturing skill with a short didactic course and individual proctoring. A suturing assist device decreases time required by inexperienced surgeons to device perform an intracorporeal tie.
