Simple continuous suture versus continuous horizontal mattress suture for plication of abdominal fascia: which is...

Abdominal fascia plication using a simple continuous suture can sometimes cause tears in the fascia. This problem can be circumvented when the continuous horizontal mattress suture is used. No data exist from comparing the two suturing techniques. The aim of this study was to examine which technique can potentially cause greater tissue damage. The time required to perform each type of suture was also recorded.

Wound closure pads were plicated using the simple continuous and continuous horizontal mattress techniques performed by a single operator using Ethilon 2-0 nylon sutures. To verify their resilience, plastic bags were inflated beneath the pads to 30, 60, and 120 mmHg and tears were recorded. The time needed to perform the procedures was recorded using a stopwatch.

Mean time for the continuous vertical mattress suture was 87 s and for the simple continuous suture 116 s. Tears in the pad that was plicated with the simple continuous pattern were significantly longer than those in the pad plicated with the continuous horizontal mattress pattern (fissure mean length ± SD = 3.958 ± 0.157 vs. 2.736 ± 0.157, respectively, p < 0.001). This finding was true for each of the three measured pressures (fissure mean length for 30 mmHg was 3.40 ± 1.807 vs. 2.12 ± 1.709 cm; for 60 mmHg, 3.94 ± 2.90 vs. 2.90 ± 1.893 cm; and for 120 mmHg, 4.54 ± 1.924 vs. 3.19 ± 2.110 cm; p < 0.001).

Continuous horizontal mattress pattern sutures were found to be superior to simple continuous pattern sutures in the suggested model, in terms of suturing time and damage to the pad. Further research in human subjects is still required.
