Surgical wounds can become infected by bacteria, regardless if the bacteria is already present on the patient's skin or if the bacteria is spread to the patient due to contact with infected individuals. [5] Wound infections can be superficial (skin only), deep (muscle and tissue), or spread to the organ or space where the surgery occurred. [5]
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.
Internal bleeding (also called internal haemorrhage) is a loss of blood from a blood vessel that collects inside the body, and is not usually visible from the outside. [1] It can be a serious medical emergency but the extent of severity depends on bleeding rate and location of the bleeding (e.g. head, torso, extremities).
Adhesions form as a natural part of the body's healing process after surgery in a similar way that a scar forms. The term "adhesion" is applied when the scar extends from within one tissue across to another, usually across a virtual space such as the peritoneal cavity. Adhesion formation post-surgery typically occurs when two injured surfaces ...
A scar (or scar tissue) is an area of fibrous tissue that replaces normal skin after an injury. Scars result from the biological process of wound repair in the skin, as well as in other organs , and tissues of the body.
The repaired region contains an abnormally large number of collagenous fibers, and relatively few blood vessels. Damaged sweat and sebaceous glands, hair follicles, muscle cells, and nerves are seldom repaired. They are usually replaced by the fibrous tissue. The result is the formation of an inflexible, fibrous scar tissue.
If the fibrosis is chronic (more than 12 weeks) there is a decreased likelihood of success with MUA, and open lysis of adhesions is sometime performed. However, this carries with it the attendant risks of another open procedure (i.e., infection, blood clots, blood loss, etc.) and the return of scar tissue.
An internal abscess is more difficult to identify and depend on the location of the abscess and the type of infection. General signs include pain in the affected area, a high temperature, and generally feeling unwell. [17] Internal abscesses rarely heal themselves, so prompt medical attention is indicated if such an abscess is suspected.
