Clinical and economic outcomes of cesarean deliveries with skin closure through skin staples plus waterproof wound dressings versus 2-octyl cyanoacrylate plus polymer mesh tape

Surgical and Clinical Outcomes Associated With the Use of Barbed Sutures and Self-Adhering Mesh System and Polymeric Glue for Wound Closure in Multilevel or Revision Spinal Surgery: A Matched Cohort Comparative Study With Conventional Wound Closure Procedure

OBJECTIVE

Multilevel or revisional posterior spinal surgery is prone to infection and delayed wound healing, related with the wound closure time and suture strength. Knotless barbed suture is an innovative self-locking, multianchor suture. This study aims to evaluate the safety and efficacy of the knotless barbed suture and self-adhering mesh with polymeric glue in multilevel or revisional posterior spinal surgery.

METHODS

This is a single-center retrospective matched cohort study. Patients were divided into 2 groups based on the wound closure method: barbed suture group with novel wound closure, and conventional suture group with conventional wound closure, 1:1 matched by the level of surgery and sex, resulting in 120 subjects each. Total operation time and wound closure time were measured intraoperatively, and perioperative clinical outcome parameters including postoperative wound complication were investigated for the first 3 months postoperatively. The distribution of continuous variables was assessed for normality by Shapiro-Wilk test, then parametric or nonparametric tests were applied accordingly (paired t-test or Wilcoxon signed-rank test).

RESULTS

Wound closure time was significantly shorter with the novel barbed suture than with conventional suture in all subgroups divided by the level of spinal surgery: 3-5, 6-9, ≥ 10 levels (p < 0.001). The 2 groups showed no significant differences in surgical complications (p = 1.000). Specially, total operation time and wound-closing time were significantly shorter in revisional subgroup.

CONCLUSION

Absorbable knotless barbed suture and self-adhering mesh with polymeric glue can shorten spinal wound closure time with noninferiority in complications for multilevel or revisional spinal surgery.

Economic and clinical outcomes of spinal fusion surgeries with skin closure through skin staples plus waterproof wound dressings versus 2-octyl cyanoacrylate plus polymer mesh tape

BACKGROUND CONTEXT

Spinal fusion surgeries are one of the most common types of operations performed during inpatient stays in the United States. Successful wound closure, including watertight closure at the skin layer, plays in important role in patient outcomes.

PURPOSE

To compare the economic and clinical outcomes of spinal fusion surgeries using one of two sutureless skin closure techniques: skin staples plus waterproof wound dressings (SSWWD) or 2-octyl cyanoacrylate plus polymer mesh tape (2OPMT).

STUDY DESIGN/SETTING

Retrospective study using a multi-hospital database.

PATIENT SAMPLE

Patients undergoing inpatient spinal fusion surgery for a spine disorder between October 1, 2015 and March 31, 2019.

OUTCOME MEASURES

Total costs from the hospital perspective, operating room time (ORT), hospital length of stay (LOS), non-home discharge, infection/wound complications during the 90-day global period (index surgery through 90 days post-discharge), and 30/60/90-day all-cause readmissions.

METHODS

Outcomes were compared between study groups using nearest neighbor propensity score matching with exact matching on 45 primary procedure/diagnosis code groupings and generalized estimating equations to account for hospital-level clustering. This study was sponsored by Ethicon, Inc., a Johnson & Johnson company; the authors are employees or consultants of Johnson & Johnson.

RESULTS

A total of 11,991 patients met the study criteria (2OPMT=5,961; SSWWD=6,030), of which 3,602 were included in each post-match study comparison group (total=7,204). As compared with the SSWWD group, the 2OPMT group had statistically significant lower median ORT (240 vs. 270 minutes; p=0.002), mean LOS (3.35 [SD=2.6] vs. 3.86 [SD=2.8] days, p=0.031), risks of non-home discharge status (17.63% vs. 23.10%, p=0.035), overall infections/wound complications (1.37% vs. 2.48%, p=0.015), and surgical site infection (1.11% vs. 2.07%, p=0.023). Differences between the study groups in total hospital costs, all-cause readmissions, and other sub-components of the infection/wound complication composite outcome were statistically insignificant (p>0.05).

CONCLUSIONS

In this retrospective observational study of patients undergoing elective inpatient spinal fusion surgery, the use of 2OPMT for skin closure was associated with significantly lower ORT, LOS, non-home discharge, and 90-day rates of infections/wound complications as compared with SSWWD.
