Objectives
To compare purse-string skin closure (PSC) and linear skin closure (LSC) techniques in patients undergoing stoma closure
Methods
We conducted a systematic review of literature and meta-analysis of outcomes according to PRISMA statement standards to compare PSC and LSC techniques in stoma closure. Trial sequential analysis (TSA) was performed to assess the possibility of type I or II error and compute the information size required for conclusive meta-analysis.
Results
We identified six randomised controlled trials (RCTs) and eight observational studies, enrolling a total of 1102 patients. The included populations in the PSC and LSC groups were comparable in terms of baseline characteristics. The risk of surgical site infection (SSI) was significantly lower in the PSC group (OR 0.10; 95% CI 0.06, 0.18; P < 0.00001). There was no difference between the two groups in terms of operative time (MD 1.80; 95% CI − 1.35, 4.96; P = 0.26), anastomotic leak (OR 0.73; 95% CI 0.21, 2.48; P = 0.61), incisional hernia (OR 0.59; 95% CI 0.25, 1.37; P = 0.22), small bowel obstruction (OR 0.96, 95% CI 0.50, 1.86; P = 0.91), and length of hospital stay (MD − 0.04; 95% CI − 0.51, 0.42; P = 0.86). Patient satisfaction was higher in the PSC group. TSA showed that the risk of type 1 error was minimal and meta-analysis was conclusive.
Conclusions
PSC is associated with significantly lower risk of SSI and better patient satisfaction compared with LSC in closure of stomas and should be the closure technique of choice. The current available evidence is robust and conclusive highlighting that the results of the current study should be incorporated into clinical practice without a need for further trial data.
