As minimally invasive techniques become increasingly central in surgery, the demand for precision grows. In this context, the present pilot study aims to investigate whether spatial metrics of suture placement can quantitatively reflect mechanical performance and to determine how operator experience and surgical platform influence technical outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fifteen participants, stratified by prior experience in minimally invasive surgery, performed standardized suturing tasks on porcine rectal specimens using three platforms: conventional laparoscopy, the daVinci Research Kit (dVRK), and the Flex robotic endoscope. Quantitative Suture Assessment was conducted by extracting spatial features (e.g., distance variability between consecutive stitches), while mechanical resistance was evaluated via intraluminal burst pressure. Statistical analyses included correlation and regression modeling to assess the relationship between spatial metrics and burst pressure, as well as comparative analyses across platforms and experience levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Mean burst pressures measured 17.38\u2009\u00b1\u20096.54\u00a0mmHg for laparoscopy, 15.99\u2009\u00b1\u20097.69\u00a0mmHg for dVRK, and 13.60\u2009\u00b1\u200910.08\u00a0mmHg for Flex. Masters recorded a mean burst pressure of 17.95\u2009\u00b1\u20099.43\u00a0mmHg, while Advanced 13.89\u2009\u00b1\u20097.41\u00a0mmHg and Beginners 15.13\u2009\u00b1\u20097.64\u00a0mmHg. Laparoscopy achieved higher burst pressures than Flex, and dVRK outperformed Flex among Beginners.
