Facts on Removing Stitches

  • Among the many methods for closing wounds of the skin, stitching, or suturing, is the most common form of repairing a wound. Other methods include surgical staples, skin closure tapes, and adhesives.
  • Removing stitches or other skin-closure devices is a procedure that many people dread. Understanding the various skin-closure procedures and knowing how they are put in and what to expect when they are removed can help overcome much of this anxiety.
  • Stitches (also called sutures) are used to close cuts and wounds in skin. They can be used in nearly every part of the body, internally and externally. Doctors literally "sew" the skin together with individual sutures and tie a secure knot. Stitches then allow the skin to heal naturally when it otherwise may not come together.
  • Stitches are used to close a variety of wound types. Accidental cuts or lacerations are often closed with stitches. Also, surgeons use stitches during operations to tie ends of bleeding blood vessels and to close surgical incisions.
  • Sutures are divided into two general categories, namely, absorbable and nonabsorbable.
    • Absorbable sutures rapidly break down in the tissues and lose their strength within 60 days. This type of suture does not have to be removed. These are used to close skin and for other internal uses where a permanent stitch is not needed.
    • Nonabsorbable sutures, on the other hand, maintain their strength for longer than 60 days. These sutures are used to close skin, external wounds, or to repair blood vessels, for example. They may require removal depending on where they are used, such as once a skin wound has healed.
  • The general technique of placing stitches is simple. The "thread" or suture that is used is attached to a needle. The wound is usually cleaned with sterile water and peroxide. Betadine, an antiseptic solution, is used to cleanse the area around the wound. Next, the area is numbed with an anesthetic agent such as lidocaine (Xylocaine). Then the needle with the thread attached is used to "sew" the edges of the wound together, in an effort to recreate the original appearance. Several stitches may be needed to accomplish this. Once the wound is closed a topical antibiotic gel is often spread over the stitches and a bandage is initially applied to the wound. All sutured wounds that require stitches will have scar formation, but the scarring is usually minimal.
  • Surgical staples are also useful for closing many types of wounds. Staples have the advantage of being quicker and may cause fewer infections than stitches. Disadvantages of staples are permanent scars if used inappropriately and imperfect aligning of the wound edges, which can lead to improper healing. Staples are used on scalp lacerations and commonly used to close surgical wounds.
  • Skin closure tapes, also known as adhesive strips, have recently gained popularity. The advantages of skin closure tapes are plenty. The rate of wound infection is less with adhesive strips than with stitches. Also, it takes less time to apply skin closure tape. For many people, there is no need for a painful injection of anesthetic when using skin closure tapes. Disadvantages of using skin closure tapes include less precision in bringing wound edges together than suturing. Not all areas of the body can be taped. For example, body areas with secretions such as the armpits, palms, or soles are difficult areas to place adhesive strips. Areas with hair also would not be suitable for taping.
  • Adhesive agents can also be used to close a wound. This material is applied to the edges of the wound somewhat like glue and should keep the edges of the wound together until healing occurs. Adhesive glue is the newest method of wound repair and is becoming a popular alternative to stitches, especially for children. The adhesive simply falls off or wears away after about 5-7 days.

Removing Stitches Preparation

If a person has received stitches, they should be given instructions for taking care of the stitches and wound, and be given an approximate date to have the stitches removed. A sample of such instructions is as follows:

  • Keep wound clean and dry for the first 24 hours.
  • Showering is allowed after 48 hours, but do not soak the wound.
  • Bandages can safely be removed from the wound after 48 hours, unless the wound continues to bleed or has a discharge. If bandages are kept in place and get wet, the wet bandage should be replaced with a clean dry bandage.
  • An antibiotic ointment (brand names are Polysporin or Neosporin, for example) should be used after the wound is cleaned.
  • Notify the doctor if a suture loosens or breaks.
  • When scheduled to have the stitches removed, be sure to make an appointment with a person qualified to remove the stitches.

Different parts of the body require suture removal at varying times. Common periods of time for removal are as follows, but times vary according to the health care professionals that perform the procedure:

  • Face:  3-5 days
  • Scalp: 7-10 days
  • Trunk: 7-10 days
  • Arms and legs: 10-14 days
  • Joints: 14 days

Sutures may be taken out all at one visit, or sometimes, they may be taken out over a period of days if the wound requires it.

During Removing Stitches Procedure

  • The wound is cleaned with an antiseptic to remove encrusted blood and loosened scar tissue.
  • Sterile forceps (tongs or pincers) are used to pick up the knot of each suture, and then surgical scissors or a small knife blade is used to cut the suture. Forceps are used to remove the loosened suture and pull the thread from the skin.
  • These relatively painless steps are continued until the sutures have all been removed. You may feel a tug or slight pull as a stitch is removed.
  • The wound is cleansed again.
  • Adhesive strips are often placed over the wound to allow the wound to continue strengthening.

Removing staples

  • Staple removal is also a simple procedure and is similar to suture removal. Doctors use a special instrument called a staple remover.
  • After cleansing the wound, the doctor will gently back out each staple with the remover. The doctor applies pressure to the handle, which bends the staple, causing it to straighten the ends of the staple so that it can easily be removed from the skin. The staple backs out of the skin the very same direction in which it was placed. People may feel a pinch or slight pull.
  • The process is repeated until all staples are removed. The wound is cleansed a second time, and adhesive strips are applied. This is also a relatively painless procedure.

After Removing Stitches Procedure

Wound care after suture removal is just as important as it was prior to removal of the stitches. Take good care of the wound so it will heal and not scar.

  • Keep adhesive strips on the wound for about 5 days. Then soak them for removal. Do not peel them off.
  • Continue to keep the wound clean and dry.
  • Skin regains tensile strength slowly. At the time of suture removal, the wound has only regained about 5%-10% of its strength. Therefore, protect the wound from injury during the next month.
  • Injured tissue also requires additional protection from sun's damaging ultraviolet rays for the next several months. The use of sunscreen during this period of healing is advised for those areas that are exposed.
  • The use of vitamin E topically has also been suggested to be helpful in the healing process of the damaged skin. This should only be considered once the skin edges are healed and are closed together.

When to Seek Medical Care after Stitches Removal

If the following signs of infection adjacent to the sutures are present, call the doctor.

  • Redness
  • Increasing pain
  • Swelling
  • Fever
  • Red streaks progressing away from the sutured site
  • Material coming from out of the wound
  • If the wound reopens and bleeding occurs, call the doctor.

Complications of Removing Stitches

  • Wound infection: If signs of infection begin, such as redness, increasing pain, swelling, and fever, contact a doctor immediately.
  • Wound reopening: If sutures are removed too early, or if excessive force is applied to the wound area, the wound can reopen. The doctor may restitch the wound or allow the wound to close by itself naturally to lessen the chances of infection.
  • Excessive scarring: All wounds will form a scar, and it will take months for a scar to completely contract and remodel to its permanent form. However, scarring may be excessive when sutures are not removed promptly or left in place for a prolonged period of time. This may result in a scar with the appearance of a "railroad track."
  • Keloid formation: A keloid is a large, firm mass of scarlike tissue. This scarring extends beyond the original wound and tends to be darker than the normal skin. Keloids are common in wounds over the ears, waist, arms, elbows, shoulders, and especially the chest.
    • Keloids occur when the body overreacts when forming a scar. They are common in African Americans and in anyone with a history of producing keloids. People with a tendency to form keloids should be closely monitored by the doctor. Injection of anti-inflammatory agents may decrease keloid formation. Also, large keloids can be removed, and a graft can be used to close the wound.
  • Hypertrophic scars: Bulky scars can remain within the boundaries of the original wound. These occur mostly around joints. Hypertrophic scars tend to develop a peak size and then get smaller over months to years. Keloids, on the other hand, rarely go away. For people with hypertrophic scars, a firm pressure dressing may aid in preventing them from forming.
