Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response , the proliferation of cells and tissues that initiate healing , and the final remodeling .
It is known as an interrupted stitch because the individual stitches aren't connected; they are separate. Placing and tying each stitch individually is time-consuming, but this technique keeps the wound together even if one suture fails. [1] It is simple, and relatively easy to place. A surgeon's knot or knots cross the wound perpendicularly ...
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material ...
The vertical mattress stitch is most commonly used in anatomic locations which tend to invert, such as the posterior aspect of the neck, and sites of greater skin laxity such as the closure of lax skin after removing a dermoid cyst or reduced subcutaneous tissue (e.g., the shin) that do not provide adequate subcutaneous tissue for dermal closure.

The wound can be allowed to close by secondary intention. Alternatively, if the infection is cleared and healthy granulation tissue is evident at the base of the wound, the edges of the incision may be reapproximated, such as by using butterfly stitches , staples or sutures .
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Wound dehiscence following an inguinal hernia repair. Wound dehiscence is a surgical complication in which a wound ruptures along a surgical incision . Risk factors include age, collagen disorder such as Ehlers–Danlos syndrome , diabetes , obesity , poor knotting or grabbing of stitches , and trauma to the wound after surgery.
Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds or to resect and/or connect parts of an organ (e.g. bowels, stomach or lungs). The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close a defect. [1]
