Surgical suture tension during hand-knotting is not reproducible and does not improve with surgeon experience. Individual feeling, not expertise, dictates knotting tension in surgical procedures.

Area of Science:

  • Surgical technique
  • Biomechanical analysis
  • Medical device engineering

Background:

  • Hand-knotting sutures remains a critical skill in surgical procedures like laparotomy closure.
  • Surgeon experience and subjective judgment are traditionally believed to influence suturing technique.
  • The reproducibility of suture tension in manual knotting has not been thoroughly investigated.

Purpose of the Study:

  • To determine if suture tension applied during manual knotting is reproducible.
  • To assess the impact of surgical experience on the reproducibility of suture tension.
  • To investigate the consistency of manual suturing techniques in surgical practice.

Main Methods:

  • 118 surgeons performed five repetitive sutures on a certified tension-measuring device.

  • Surgeons were categorized into five experience-based subgroups (0-30+ years).
  • Suture tension was measured in Newtons during the knotting process.

    • Main Results:

    • Measured suture tension varied widely, ranging from 0.19 to 10 N.
    • Mean suture tension showed no significant difference across experience groups.
    • Suture tension was found to be irreproducible, irrespective of the surgeon's experience level.

    Conclusions:

    • Manual suture tension is not reproducible, even among highly experienced surgeons.
    • Current suturing tension appears to be based on subjective estimation rather than objective measurement.
    • Further research is needed to define ideal, tissue-dependent suture tension standards.
