Comparison of incisional bursting strength of a bidirectional absorbable knotless suture material versus a standard continuous absorbable suture material for closure of the equine linea alba.

Abstract: To evaluate the use of bidirectional knotless barbed suture material for closure of the equine linea alba. Methods: Laboratory study. Methods: Adult light horse cadavers (n = 24). Methods: A 25 cm incision was made through the linea alba, and a 200 L polyurethane bladder was positioned within the abdomen. The linea alba was closed either using USP2/EP5 bidirectional polydioxanone barbed suture or USP2/EP5 standard polydioxanone suture in a simple continuous pattern. Closure time was recorded for each suture type. The bladder was air-insufflated at 40 L/min, and the pressure at body wall failure recorded. The length of suture used for wound closure and wound failure modes were recorded. Suture length, closure time, bursting pressure, and failure modes were compared using Welch-Aspin t-tests. Results: The incisional bursting pressure was comparable between the two groups (p > .05). Less suture material (p < .01) was required with the barbed suture than the standard suture. Closure time was less for the barbed suture than the standard suture (p < .01). Suture failure was the main failure mode in both groups (83% cases). Conclusions: Closure of the equine linea alba using bidirectional barbed suture material reduced the amount of foreign material in the wound and decreased closure time without compromising incisional strength. Conclusions: Bidirectional barbed suture material could be considered as an alternative to standard suture materials for closure of the equine line alba.

This study compares the effectiveness of a bidirectional absorbable knotless suture material with a standard continuous absorbable suture material for closing abdominal incisions in horses. The key findings reveal that the use of bidirectional barbed suture material decreases the quantity of foreign material in the wound and reduces closure time without sacrificing incisional strength.

Experimental Procedure

  • Adult light horse cadavers (24 in total) were used in the experiment. A 25 cm incision was made through the linea alba (the midline of the abdomen). A 200 L polyurethane bladder was then placed inside the abdomen.
  • The linea alba was sealed either using DS26 bidirectional polydioxanone barbed suture or USP2/EP5 standard polydioxanone suture. This suture process was timed for each type.
  • The bladder was filled with air at a rate of 40 L/min. The pressure at which the body wall failed was then recorded.
  • The length of suture used for wound closure and the modes of wound failure were also documented. These data points, along with closure time and bursting pressure, were compared using a statistical test known as the Welch-Aspin t-tests.

Results

  • The incisional bursting pressure (the pressure that the sutured incision could withstand before bursting) was found to be similar between the two groups (p > .05).
  • Less suture material was needed with the barbed suture than with the standard suture (p < .01).
  • The closure time was also shorter for the barbed suture than for the standard suture (p < .01).
  • The majority of failures in both groups (83% of cases) were due to the sutures themselves failing.

Final Conclusions

  • Using a bidirectional barbed suture material to close the equine linea alba reduced both the amount of foreign material in the wound and the closure time. It did not weaken the strength of the incision.
  • The authors suggest that bidirectional barbed suture material could be considered as a potential alternative to standard suture materials for closure of the linea alba in horses.
