To design an experimental model by which it would be possible to measure exactly the total amount of suture material required for interrupted and continuous closure of the abdominal fascia.
Laboratory study.
160 Patches of 1 mm thick synthetic material (silicone) 25 x 8 cm in which a midline incision had been made and sutured with absorbable sutures, either braided polyglycolic acid or monofilament polyglyconate, using a standard knot under standard tension.
Length of suture material used when sutures placed either 2 or 1.5 cm from the cut edge and with 1 or 1.5 cm left between sutures. Each series of measurements was made 10 times.
When the distance from the cut edge, the distance between sutures, and the suture material were standardised continuous suturing used less material than interrupted. Slightly less polyglycolic acid was needed than polyglyconate. More suture material (9-15%) was required for continuous sutures 1 cm apart compared with interrupted sutures 1.5 apart, when both were inserted 1.5 cm from the cut edge, but the difference was smaller when polyglyconate was used than when polyglycolic acid was used.
The differences in lengths of suture material required do not outweigh the mechanical advantages of continuous closure of the fascia.
设计一种实验模型，通过该模型能够精确测量间断缝合和连续缝合腹部筋膜所需缝合材料的总量。
实验室研究。
160块1毫米厚的合成材料（硅胶）片，尺寸为25×8厘米，在其上作中线切口并用可吸收缝线缝合，缝线为编织聚乙醇酸或单丝聚甘醇酸酯，在标准张力下使用标准结。
缝线距切缘2厘米或1.5厘米且缝线间距为1厘米或1.5厘米时所用缝合材料的长度。每个测量系列重复10次。
当切缘距离、缝线间距和缝合材料标准化时，连续缝合比间断缝合使用的材料少。聚乙醇酸比聚甘醇酸酯所需的材料略少。当二者均距切缘1.5厘米插入时，连续缝线间距1厘米比间断缝线间距1.5厘米需要更多的缝合材料（9%-15%），但使用聚甘醇酸酯时的差异比使用聚乙醇酸时小。
所需缝合材料长度的差异并不超过筋膜连续缝合的机械优势。
