Objective:
The objective of this article is to systematically analyse the randomized, controlled trials comparing the effectiveness of purse-string closure (PSC) of an ileostomy wound with conventional linear closure (CLC).
Methods:
Randomized, controlled trials comparing the effectiveness of purse-string closure vs conventional linear closure (CLC) of ileostomy wound in patients undergoing ileostomy closure were analysed using RevMan®, and the combined outcomes were expressed as risk ratio (RR) and standardized mean difference (SMD).
Results:
Three randomized, controlled trials, recruiting 206 patients, were retrieved from medical electronic databases. There were 105 patients in the PSC group and 101 patients in the CLC group. There was no heterogeneity among included trials. Duration of operation (SMD: -0.18; 95% CI: -0.45, 0.09; z = 1.28; P < 0.20) and length of hospital stay (SMD: 0.01; 95% CI: -0.26, 0.28; z = 0.07; P < 0.95) was statistically similar following both approaches of ileostomy wound closure. The risk of surgical site infection (OR, 0.10; 95% CI: 0.03, 0.33; z = 3.78; P < 0.0001) was significantly reduced when ileostomy wound was closed using PSC technique.
Conclusion:
PSC technique for ileostomy wound is associated with a reduced risk of surgical site infection apparently without influencing the duration of operation and length of hospital stay.

01:24Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
