Comparison of incisional bursting strength of simple continuous and inverted cruciate suture patterns in the equine linea alba.
Abstract: To determine the bursting strength of ventral median abdominal incisions closed by either simple continuous or inverted cruciate suture patterns. Methods: Experimental. Methods: Twelve equine cadavers. Methods: A 25 cm ventral median incision was made through the linea alba and a 200 L polyurethane bladder was placed within the abdomen. Either a simple continuous or an inverted cruciate pattern using 3 polyglactin 910 with a bite size and suture interval of 1.5 cm was used to close linea incisions. Closure time was recorded for each pattern. The bladder was inflated with air at 40 L/min, and the pressure at body wall failure recorded. The length of suture used for wound closure and the wound failure modes were recorded. Deviation from the linea (cm), total suture length (cm), suture length to wound length ratio (SL:WL), closure time (min), bursting pressure (mm Hg), and failure modes were compared between groups using Welch-Aspin t-tests. The effects of independent subject variables were assessed for possible effects on bursting strength using analysis of covariance. Results: Mean bursting pressure was significantly greater for the simple continuous pattern than for the inverted cruciate pattern (P = .01). Significantly less suture material (P = .0002) was required with the continuous pattern than with the inverted cruciate pattern. Mean closure time, SL:WL, deviation from the linea, and failure modes were not significantly different between groups. No significant effects were noted for independent variables in both groups on bursting strength. Conclusions: In this model, a simple continuous closure pattern for ventral median abdominal incisions was stronger than an inverted cruciate pattern. A simple continuous pattern leaves less foreign material in the wound, which may be of benefit in reducing incisional complications. Conclusions: Use of a continuous closure pattern for the linea alba may offer greater wound security during episodes of increased intra-abdominal pressure in horses.

This research investigates the bursting strength of horse abdominal incisions closed by either a simple continuous or inverted cruciate suture pattern. It found that the simple continuous suture pattern is stronger and uses less suture material, which may help lessen incisional complications.
Research Methodology
- Two suture patterns—simple continuous and inverted cruciate—were tested in this experiment on twelve horse cadavers.
- A central abdominal incision was made and a bladder filled with air inserted for each experiment. The abdominal incision was then closed using one of the two suture techniques.
- The bladder was inflated at a steady rate and measurements were recorded, primarily the pressure at which the sutured incision gave way (i.e., ‘bursting strength’). The amount of suture used, time taken to close the wound, and the manner in which the wound failed, were also registered.
- Statistical analysis was then conducted to compare the results from each suture technique; in particular, an analysis of covariance was employed to factor out any potentially biasing individual variations in bursting strength.
Results and Interpretation
- The results showed that simple continuous sutures had significantly greater bursting strength as compared to the inverted cruciate pattern.
- The simple continuous suture technique also used significantly less suture material than the inverted cruciate technique.
- Other factors measured, such as closure time, the ratio of suture length to wound length, degree of deviation from the straight line, and modes of failure, were not significantly different between the two techniques.
- No unexpected influence factors were identified that might have an impact on the bursting strength.
Conclusion
- Based on these results, the study concluded that the simple continuous suture pattern offers higher security for closing ventral median abdominal incisions in horses.
- This pattern leaves less foreign material in the wound, which can potentially reduce incisional complications.
- The study suggests that a simple continuous suture pattern might be more advantageous particularly during instances of increased intra-abdominal pressure in horses.
