The current surgical literature has not clearly demonstrated an optimal tec
hnique for abdominal closure. Prospective randomized studies published betw
een 1980 and 1998 were analyzed and the relevant data derived from those st
udies were pooled for statistical evaluation. The outcome variables of dehi
scence, infection, hernia formation, suture sinus formation, and pain were
studied and the probability of their occurrence in association with differe
nt techniques was calculated. In relation to the outcome features of dehisc
ence and infection no statistically significant difference was seen when ab
sorbable suture material was compared with nonabsorbable material. In regar
d to the probability of hernia formation no statistically significant diffe
rence was seen when monofilament absorbable material was compared with nona
bsorbable material. There was, however, a higher incidence of hernia format
ion when braided absorbable suture material was used. In addition there was
a higher incidence of incision pain and suture sinus formation when nonabs
orbable suture material was used. Absorbable monofilament suture material i
s superior to both absorbable braided and nonabsorbable suture for abdomina
l fascial closure. A continuous mass (all-layer) closure with absorbable mo
nofilament suture material is the optimal technique for fascial closure aft
er laparotomy.
