OBJECTIVE: To systematically analyse the effectiveness of delayed-absorbable (Polydioxanone; PDS) versus non-absorbable (Polypropylene; Prolene, and Nylon) for abdominal fascial closure in patients undergoing laparotomy.

METHODS: Randomised trials evaluating PDS versus Prolene/Nylon for abdominal fascial closure were selected and analysed by using the statistical tool RevMan where summative data was expressed as odds ratio (OR).

RESULTS: Eight randomised trials encompassing 4261 patients undergoing laparotomy closure with either PDS or Prolene/Nylon were retrieved. There was no statistically significant heterogeneity among trials. In the fixed effect model PDS was comparable to Prolene/Nylon in terms of risk of incisional hernia (OR, 1.10; 95% CI, 0.87, 1.37; z = 0.79; p = 0.43), wound dehiscence (OR, 1.04; 95% CI, 0.67, 1.62; z = 0.19; p = 0.85), peri-operative complications (OR, 0.94; 95% CI, 0.66, 1.33; z = 0.37; p = 0.71), suture sinus formation (OR, 0.58; 95% CI, 0.33, 1.04; z = 1.84; p = 0.07) and surgical site infection (OR, 0.98; 95% CI, 0.68, 1.39; z = 0.14; p = 0.89). Subgroup analysis separately comparing Prolene and Nylon with PDS supported same outcome.

CONCLUSION: PDS and Prolene/Nylon are equally effective for the closure of abdominal fascia following laparotomy. Given that there are no significant differences between two suture materials, further studies may be conducted to evaluate their cost-effectiveness and measurement of health-related quality of life instead of analysing their effectiveness in laparotomy closure.
