From the Guidelines
A lump under a stab wound closed with staples and dissolvable sutures is likely normal scar tissue formation or fluid collection (seroma) that typically resolves on its own within a few weeks. Monitor the area for signs of infection such as increasing redness, warmth, severe pain, pus drainage, fever, or red streaks extending from the wound. Keep the wound clean and dry, and follow your healthcare provider's instructions for wound care. You can apply gentle ice for 15-20 minutes several times daily to reduce swelling, and take acetaminophen (Tylenol) as directed for discomfort. Avoid manipulating or squeezing the lump as this could introduce infection or disrupt healing. The lump forms as part of the normal healing process as your body repairs damaged tissue and creates collagen to strengthen the wound.
Some key points to consider in wound care include:
- The method of skin closure may have a role in preventing the development of surgical site infections (SSIs), with continuous sutures potentially providing a better seal than interrupted sutures 1.
- Advanced dressings should not be used for primarily closed surgical wounds for the purpose of preventing SSI, and the surgical wound dressing can be removed for a minimum of 48 hours after surgery unless leakage occurs 1.
- If signs of infection develop, such as increasing redness, warmth, severe pain, pus drainage, fever, or red streaks extending from the wound, contact your healthcare provider promptly for evaluation. In some cases, antibiotics may be necessary, but this is typically only for more severe infections or those with significant systemic signs 1.
It is essential to prioritize wound care and monitoring to prevent complications and promote healing. If the lump grows larger, becomes more painful, or doesn't improve within 2-3 weeks, or if you develop signs of infection, contact your healthcare provider promptly for evaluation.
From the Research
Wound Closure Methods
- The use of staples and dissolvable sutures for closing stab wounds is a common practice in emergency care 2, 3.
- The choice of closure method depends on the complexity and location of the wound, as well as the patient's overall health status 3.
- Studies have compared the effectiveness of staples and sutures for skin closure, with some finding that sutures may result in slightly fewer overall wound infections 4.
Complications and Considerations
- The development of a lump under a stab wound closed with staples and dissolvable sutures may be a sign of infection or other complications 5, 6.
- Antibiotics may be prescribed to prevent or treat infections, with cephalexin being a commonly used antibiotic for skin and soft-tissue infections 5.
- The management of abdominal stab wounds requires careful evaluation and treatment, with algorithms and guidelines available to guide healthcare professionals 6.
