Monofilament versus multifilament absorbable sutures for abdominal closure

Abstract

Abstract This study compares monofilament continuous absorbable sutures with multifilament interrupted absorbable sutures for abdominal closure. Before closure of an abdominal ineision, 988 patients were randomized to receive either a monofilament polyglyconate (Maxon) or a multifilament polyglactin 910 (Vicryl) suture. At 1 year after operation, 684 patients (69 per cent) were examined for the presence of incisional hernia, sinus and other wound-healing problems; 179 (18 per cent) had died and 125 (13 per cent) did not attend for follow-up. Incisional hernia occurred in 8 per cent of patients receiving monofilament continuous sutures compared with 6 per cent of those having multifilament interrupted closure (P not significant). Wound dehiscence occurred in 1 per cent of both groups. The mean time for suturing was 7.1 min for monofilament continuous and 8.7 min for multifilament interrupted sutures (P <0.001). It is concluded that closure of an abdominal incision can be effected by a monofilament continuous absorbable suture more quickly than by multifilament interrupted absorbable sutures without an increased risk of wound dehiscence or incisional hernia.
