Abstract:
The postoperatively retained foreign body (PORFB) can induce complications leading to the need for follow-up surgery to ensure its removal, to treat or prevent the formation of an abscess, and to minimize the risk of death for the patient and liability for the surgeon and hospital. The most common cause of PORFB complications is the surgical sponge. Previously, PORFB prevention was focused on improved efficiency in RFB counting; however, because of the inability to entirely eliminate human error, cost, and the potentially unproven patient outcome improvement, new approaches have been sought. We examined the use of a novel bioengineered, biodegradable sponge (BSS) to reduce the risk of complications due to PORFBs, thus potentially improving patient outcomes.
Insights
Postoperatively retained foreign bodies (PORFBs), often surgical sponges, cause complications. A novel bioengineered, biodegradable sponge (BSS) was examined to reduce PORFB risks and improve patient outcomes.
Area of Science:
- Medical Devices
- Biomaterials
- Surgical Innovation
Background:
- Postoperatively retained foreign bodies (PORFBs) are a significant concern in surgery.
- Surgical sponges are the most common cause of PORFBs, leading to complications like abscess formation and requiring reoperation.
- Current prevention methods, primarily sponge counting, are fallible due to human error and associated costs.
Purpose of the Study:
- To evaluate a novel bioengineered, biodegradable sponge (BSS) as a solution to mitigate PORFB complications.
- To assess the potential of BSS to improve patient outcomes by reducing the incidence of retained surgical items.
Main Methods:
- Investigation of a newly developed bioengineered and biodegradable sponge (BSS).
- Assessment of the BSS's efficacy in preventing complications associated with retained foreign bodies in a surgical context.
Main Results:
- The study examined the use of a novel bioengineered, biodegradable sponge (BSS).
- The research aimed to reduce the risk of complications arising from postoperatively retained foreign bodies (PORFBs).
Conclusions:
- The introduction of a bioengineered, biodegradable sponge (BSS) offers a promising approach to minimize risks associated with retained surgical sponges.
- This innovation has the potential to enhance patient safety and reduce surgical liability.
