Suture or Staple for Tertiary or Higher-Order C-Section Closure?

image_pdfFavoriteLoadingFavorite

BACKGROUND AND PURPOSE: 

  • Data supports skin closure for cesarean sections with subcuticular suture rather than staples  
  • Fox et al. (Obstet Gynecol., 2018) compared wound complications in women who received suture vs staple closure technique during tertiary or higher-order C-section

METHODS: 

  • Retrospective cohort study  
  • Participants: Women undergoing tertiary or higher-order C-sections  
  • Cohorts not overlapping 
    • Prior to 2011 standard was staple closure, with suture closure beginning in spring of 2011  
  • Patients received  
    • Appropriate prophylactic antibiotics  
    • Group practice is to close all layers (including peritoneum and rectus muscles) 
    • Closure of subcutaneous tissue if ≥2 cm  
    • Postop subcutaneous heparin if BMI >40  
  • Decision of staples vs suture left to surgeon’s discretion  
  • Staples: Removed postop day 4-7 
  • Sutures: Running subcuticular suture of either 3-0 poliglecaprone (Monocryl) or 4-0 polyglactin (Vicryl) suture  
    • Wound closure strips removed 2 weeks later  
  • Primary outcome: Wound complication, defined as  
    • Wound infection requiring antibiotics or  
    • Wound separation requiring wound packing or  
    • Reclosure any time up to 6 weeks after delivery 

RESULTS: 

  • 551 patients were involved in the study 
    • 192 (34.8%) received staple closure 
    • 359(65.2%) received suture closure 
  • Suture closure was associated with a lower rate of wound complication (P=0.003) 
    • Suture: 4.7% (95% CI 3.0%-7.5%) 
    • Staple: 11.5% (95% CI 7.7%-16.7%) 
  • Suture closure remained independently associated with a lower risk of a wound complication even after controlling for number of prior C-sections and participation of a resident in the closure 
    • Adjusted odds ratio 0.44 (95% CI 0.23-0.86) 
  • Suture closure was associated with 
    • Longer operative time of approximately 10 minutes 
    • Shorter hospital stay (3 vs 4 days)

CONCLUSION: 

  • Suture closure is associated with an approximately 50% lower risk of wound complication (separation or infection) in women receiving a tertiary or higher-order C-section 
  • These data are in keeping with similar results for first or second cesarean section (see ‘Related ObG Topics’ below)
