Abstract

Aim Intracorporal knot tying (ICKT) and suturing in minimally invasive surgery (MIS) are key skills for advanced procedures. The best choice for an intracorporal slipping knot tying technique had not been defined. The aim of this study was to compare two intracorporal slipping knot techniques: the classical C-loop technique (Variant I) and the square-to-slip technique without changing leadership hand (Variant II). Methods A laparoscopic box trainer including laparoscope was used for ICKT. A total of 120 slipping knots were evaluated in two groups with different levels of surgical education. The first group (n = 5) consisted of senior surgical physicians proficient in laparoscopic surgery. The second group (n = 10) comprised medical students without any prior experience in laparoscopic surgery. The medical student group received a 1-hour hands-on training session. Participants were assessed using the Global Rating Scale of the Objective Structured Assessment of Technical Skills, procedural implementation, knot quality, and task time. Results In the medical student group, performance in all parameters was greater for Variant I compared with Variant II (P < .005). Contrary to the students group, senior physicians demonstrated significantly faster task time in Variant II compared with Variant I (P = .001). No significant differences were observed in the remaining parameters. Conclusion For novices, the intracorporal slipping knot is easier to learn with the C-loop technique (Variant I) than with the square-to-slip technique (Variant II). For surgeons experienced in MIS, the square-to-slip technique without changing leadership hand (Variant II) was superior to the slipping knot in the C-loop technique (Variant I) only by time savings. The knot quality, as the most important variable, showed equally good results between both ICKT techniques.
