Barrier agents for adhesion prevention after gynaecological surgery

Area of Science:

• Gynecological Surgery
• Adhesion Prevention
• Reproductive Medicine

Background:

• Pelvic adhesions can arise from inflammation, endometriosis, or surgical trauma.
• Synthetic barriers are used during pelvic surgery to minimize adhesion formation.
• Common barriers include oxidized regenerated cellulose, polytetrafluoroethylene, and fibrin sheets.

Purpose of the Study:

• To evaluate the efficacy of physical barriers in preventing pelvic adhesion reformation.
• To assess the impact of these barriers on pregnancy rates and pelvic pain.
• To compare different types of physical barriers used in gynecological surgery.

Main Methods:

• Systematic review of randomized controlled trials (RCTs) comparing physical barriers to no treatment or other barriers.
• Searched multiple databases including MEDLINE, EMBASE, CINAHL, PsycINFO, and CENTRAL.
• Included trials focused on women undergoing gynecological surgery for adhesion prevention.

Main Results:

• Sixteen RCTs were included, utilizing laparoscopy or laparotomy.
• Interceed demonstrated a reduction in pelvic adhesion formation but lacked data on pregnancy or pain outcomes.
• Gore-Tex showed superior adhesion prevention compared to no barrier or Interceed.
• Limited evidence supported Seprafilm, and no evidence supported Fibrin sheets for adhesion prevention.

Conclusions:

• Interceed reduces adhesion incidence but does not improve pregnancy rates.
• Gore-Tex may be more effective than Interceed but has practical limitations.
• Seprafilm and Fibrin sheets showed no evidence of effectiveness in preventing adhesions.
