Abstract

Cesarean delivery is a commonly performed surgical procedure worldwide. There is limited good-quality evidence regarding subcuticular skin closure with absorbable sutures in transverse incisions after cesarean delivery. This study aimed to compare poliglecaprone-25 (3-0) and polyglactin-910 (4-0) sutures for subcuticular skin closure in Pfannenstiel incisions among women undergoing cesarean delivery. In this double-blind, single-center, randomized controlled trial among women undergoing cesarean delivery (elective and emergency), 200 women were randomized (Group 1-subcuticular skin closure with poliglecaprone-25 [3-0] vs Group 2-subcuticular skin closure with polyglactin-910 [4-0]). All women received similar preoperative and postoperative care. A sample size of 200 women was selected with the aim of reducing the composite wound complication rate from 15.8% to 3.6% with a power of 0.80 and a 2-tailed α of 0.05. Thus, 90 women were required in each group, but 100 were selected to account for attrition. Composite wound complications (including surgical site infection, hematoma, seroma, need for resuturing or readmission for wound complications) were similar in the 2 groups (Group 1 vs 2: 16 vs 10; P=.293; relative risk, 1.28; 95% confidence interval, 0.91-1.79). Surgical site infection (8 vs 7; P=1.000; relative risk, 1.08; 95% confidence interval, 0.64-1.83), hematoma (1 vs 2; P=.561; relative risk, 0.66; 95% confidence interval, 0.13-3.31), seroma (8 vs 2; P=.052; relative risk, 1.65; 95% confidence interval, 1.17-2.33), need for resuturing (4 vs 3; P=.700; relative risk, 1.15; 95% confidence interval, 0.60-2.22), and need for readmission (4 vs 4; P=1.000) were similar in the 2 groups. Pain score on the visual analog scale at 3 days (3.2±1.0 vs 3.6±1.2) and 6 weeks after operation (1.6±0.8 vs 1.7±0.9;) was significantly lower in Group 1 (P=.023 and P=.033, respectively). There was no difference between observer and patient scar assessment scores measured at 6 weeks after operation (P=.069 and P=.431, respectively). Poliglecaprone-25 (3-0) and polyglactin-910 (4-0) subcuticular sutures were comparable regarding composite wound complications (surgical site infection, hematoma, seroma, wound separation or re-suturing, need for readmission) and cosmetic appearance (patient scar assessment score & observer scar assessment score) related to skin closure among women undergoing cesarean delivery through a Pfannenstiel incision in nonobese women (average body mass index, 25).
