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. Postoperative wounds are different from other wounds in that they are anticipated and treatment is usually standardized depending on the type of surgery performed. Since the wounds are 'predicted' actions can be taken beforehand and after surgery that can reduce complications and promote healing.[ citation needed ]
The body responds to postoperative wounds in the same manner as it does to tissue damage acquired in other circumstances. The inflammatory response is designed to create homeostasis. This first step is called the inflammatory stage. [1] The next stage and wound healing is the infiltration of leukocytes and release of cytokines into the tissue. The inflammatory response and the infiltration of leukocytes occur simultaneously. The final stage of postoperative wound healing is called remodeling. Remodeling restores the structure of the tissue and that tissues ability to regain its function.
Surgical wounds can begin to open between three and five days after surgery. The wound usually appears red and can be accompanied by drainage. Clinicians delay re-opening the wound unless it is necessary due to the potential of other complications. If the surgical wound worsens, or if a rupture of the digestive system is suspected the decision may be to investigate the source of the drainage or infection. [2] [3]
The rates of a surgical wound opening after surgery has remained constant. When a wound opens after surgery, the hospital stay becomes longer and the medical care becomes more intensive if a surgical wound opens after surgery. [2]
Infection will complicate healing of surgical wounds and is commonly observed. [2] [4] Most infections are present within the first 30 days after surgery. [5] 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] Recent studies have established that infection after surgery can occur after several years post surgery, and these infection rates are not recorded due to loss in patient follow up, hard to access record of previous surgery, visiting a new surgeon, lack of requirement from national registries etc. [6] [7]
The surgical site or wound may allow the passage of air into the body. This most often occurs after abdominal and pelvic surgery. Treatment at this point becomes more complex depending upon the extent of the opening, where it occurs and if contents of the digestive system have entered the body. [2]
The risk of complications of the surgical wound is greater for those greater than 65-years-old, or who have pulmonary disease, nutritional deficiencies, overweight, other illnesses and high blood pressure. [2]
Complications of postsurgical wounds can be reduced before, during and after surgery.
Some measures such as antibiotic prophylaxis before caesarean section and hernial repair are useful in reducing surgical site infection. Intravenous prophylactic antibiotics are recommended, to be administered within one hour from the beginning of the surgical procedure. [8] In addition to i.v. prophylaxis, oral antibiotic prophylaxis has been demonstrated to be beneficial in reducing surgical site infections after elective large bowel surgery. [9] [10] Adding a mechanical bowel cleansing in these patients might not be beneficial after colonic resection, but is still used and recommended by many before rectal resection (ideally in combination with oral antibiotics) [10] [11] [12] However, some options include antibiotic coated sutures, antibiotic impregnated cement or locally administered paste or gel. [13] [14] [15] [16] Of note, a recent randomised controlled trial performed in low- and middle-income countries did not report any reduction in surgical site infection after abdominal surgery with antiseptic (triclosan-coated) sutures. [17] There is also evidence that adhesive tapes increase infection risks. [18]
Before surgery, clinicians can treat the patient to reduce hemoglobin A1c levels to less than 7%. Those anticipating surgery can reduce their risk of complications by stopping smoking thirty days prior to surgery. The patient's skin can be evaluated for the presence of Staphylococcus aureus prior to surgery since this bacterium causes wound infections in postoperative wounds. Treating any other infections prior to surgery also reduces the risks of a postoperative wound infection. Examples of these pre-existing infections are urinary tract infection or lower reproductive system infection. Removing the hair where the skin will be cut helps to reduce the risk of complications, though shaving is not considered to be appropriate and instead depilatories are used. Those who come in contact with the person who is receiving the surgery clean and disinfect their own skin surfaces. The patient's skin is also cleaned, scrubbed and treated with antiseptics. Patients undergoing surgery often receive antibiotics before surgery. [2]
During the surgery, there are several precautions that can be taken to reduce the risk of postoperative wound complications. These are: minimizing traffic in the operating room, providing adequate ventilation, not closing wounds that are infected, minimize tissue handling, re-administer prophylactic antibiotics if large amounts of fluid are lost during surgery, and keeping the patient warm. [2] Lately, studies have highlighted new preventative measures of avoiding repeated reprocessing and intraoperatively guarding the implants in the sterile-field, for surgeries implanting single-use devices such as orthopedic and spine surgeries. [19] [20] [21] [22] [23] [24] [25]
The risk of complications after surgery can be reduced by: maintaining blood glucose levels in the normal range and constant evaluation of surgical site infection. [2] [26]
There is insufficient evidence to show that whether applying cyanoacrylate microbial sealants on the wound site before operation is effective in reducing surgical site infection post surgery. [27]
There is no evidence that one type of hand antisepsis is better than the other in preventing surgical site infection. [28] [17]
There is no evidence that plastic adhesive tapes reduces surgical site infections. [29]
The term abdominal surgery broadly covers surgical procedures that involve opening the abdomen (laparotomy). Surgery of each abdominal organ is dealt with separately in connection with the description of that organ Diseases affecting the abdominal cavity are dealt with generally under their own names.
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions, to alter bodily functions, to reconstruct or improve aesthetics and appearance, or to remove unwanted tissues or foreign bodies.
Cholecystectomy is the surgical removal of the gallbladder. Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. Cholecystectomy can be performed either laparoscopically, or via an open surgical technique.
Percutaneous endoscopic gastrostomy (PEG) is an endoscopic medical procedure in which a tube is passed into a patient's stomach through the abdominal wall, most commonly to provide a means of feeding when oral intake is not adequate. This provides enteral nutrition despite bypassing the mouth; enteral nutrition is generally preferable to parenteral nutrition. The PEG procedure is an alternative to open surgical gastrostomy insertion, and does not require a general anesthetic; mild sedation is typically used. PEG tubes may also be extended into the small intestine by passing a jejunal extension tube through the PEG tube and into the jejunum via the pylorus.
Perioperative mortality has been defined as any death, regardless of cause, occurring within 30 days after surgery in or out of the hospital. Globally, 4.2 million people are estimated to die within 30 days of surgery each year. An important consideration in the decision to perform any surgical procedure is to weigh the benefits against the risks. Anesthesiologists and surgeons employ various methods in assessing whether a patient is in optimal condition from a medical standpoint prior to undertaking surgery, and various statistical tools are available. ASA score is the most well known of these.
Colectomy is the surgical removal of any extent of the colon, the longest portion of the large bowel. Colectomy may be performed for prophylactic, curative, or palliative reasons. Indications include cancer, infection, infarction, perforation, and impaired function of the colon. Colectomy may be performed open, laparoscopically, or robotically. Following removal of the bowel segment, the surgeon may restore continuity of the bowel or create a colostomy. Partial or subtotal colectomy refers to removing a portion of the colon, while total colectomy involves the removal of the entire colon. Complications of colectomy include anastomotic leak, bleeding, infection, and damage to surrounding structures.
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
A dental extraction is the removal of teeth from the dental alveolus (socket) in the alveolar bone. Extractions are performed for a wide variety of reasons, but most commonly to remove teeth which have become unrestorable through tooth decay, periodontal disease, or dental trauma, especially when they are associated with toothache. Sometimes impacted wisdom teeth cause recurrent infections of the gum (pericoronitis), and may be removed when other conservative treatments have failed. In orthodontics, if the teeth are crowded, healthy teeth may be extracted to create space so the rest of the teeth can be straightened.
Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability, most commonly offered when joint pain is not diminished by conservative sources. It may also be performed for other knee diseases, such as rheumatoid arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause knee pain, deformity, or inflammation, and is not a reason to perform knee replacement.
Antibiotic prophylaxis refers to, for humans, the prevention of infection complications using antimicrobial therapy. Antibiotic prophylaxis in domestic animal feed mixes has been employed in America since at least 1970.
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. This procedure can be performed at any level in the spine and prevents any movement between the fused vertebrae. There are many types of spinal fusion and each technique involves using bone grafting—either from the patient (autograft), donor (allograft), or artificial bone substitutes—to help the bones heal together. Additional hardware is often used to hold the bones in place while the graft fuses the two vertebrae together. The placement of hardware can be guided by fluoroscopy, navigation systems, or robotics.
An incisional hernia is a type of hernia caused by an incompletely-healed surgical wound. Since median incisions in the abdomen are frequent for abdominal exploratory surgery, ventral incisional hernias are often also classified as ventral hernias due to their location. Not all ventral hernias are from incisions, as some may be caused by other trauma or congenital problems.
Failed Back Syndrome is a condition characterized by chronic pain following back surgeries. The term "post-laminectomy syndrome" is sometimes used by doctors to indicate the same condition as failed back syndrome. Many factors can contribute to the onset or development of FBS, including residual or recurrent spinal disc herniation, persistent post-operative pressure on a spinal nerve, altered joint mobility, joint hypermobility with instability, scar tissue (fibrosis), depression, anxiety, sleeplessness, spinal muscular deconditioning and Cutibacterium acnes infection. An individual may be predisposed to the development of FBS due to systemic disorders such as diabetes, autoimmune disease and peripheral blood vessels (vascular) disease.
Endophthalmitis, or endophthalmia, is inflammation of the interior cavity of the eye, usually caused by an infection. It is a possible complication of all intraocular surgeries, particularly cataract surgery, and can result in loss of vision or loss of the eye itself. Infection can be caused by bacteria or fungi, and is classified as exogenous, or endogenous. Other non-infectious causes include toxins, allergic reactions, and retained intraocular foreign bodies. Intravitreal injections are a rare cause, with an incidence rate usually less than 0.05%.
An open fracture, also called a compound fracture, is a type of bone fracture that has an open wound in the skin near the fractured bone. The skin wound is usually caused by the bone breaking through the surface of the skin. An open fracture can be life threatening or limb-threatening due to the risk of a deep infection and/or bleeding. Open fractures are often caused by high energy trauma such as road traffic accidents and are associated with a high degree of damage to the bone and nearby soft tissue. Other potential complications include nerve damage or impaired bone healing, including malunion or nonunion. The severity of open fractures can vary. For diagnosing and classifying open fractures, Gustilo-Anderson open fracture classification is the most commonly used method. This classification system can also be used to guide treatment, and to predict clinical outcomes. Advanced trauma life support is the first line of action in dealing with open fractures and to rule out other life-threatening condition in cases of trauma. The person is also administered antibiotics for at least 24 hours to reduce the risk of an infection.
Breast surgery is a form of surgery performed on the breast.
Vaginal evisceration is an evisceration of the small intestine that occurs through the vagina, typically subsequent to vaginal hysterectomy, and following sexual intercourse after the surgery. It is a surgical emergency.
Alloplasty is a surgical procedure performed to substitute and repair defects within the body with the use of synthetic material. It can also be performed in order to bridge wounds. The process of undergoing alloplasty involves the construction of an alloplastic graft through the use of computed tomography (CT), rapid prototyping and "the use of computer-assisted virtual model surgery." Each alloplastic graft is individually constructed and customised according to the patient's defect to address their personal health issue. Alloplasty can be applied in the form of reconstructive surgery. An example where alloplasty is applied in reconstructive surgery is in aiding cranial defects. The insertion and fixation of alloplastic implants can also be applied in cosmetic enhancement and augmentation. Since the inception of alloplasty, it has been proposed that it could be a viable alternative to other forms of transplants. The biocompatibility and customisation of alloplastic implants and grafts provides a method that may be suitable for both minor and major medical cases that may have more limitations in surgical approach. Although there has been evidence that alloplasty is a viable method for repairing and substituting defects, there are disadvantages including suitability of patient bone quality and quantity for long term implant stability, possibility of rejection of the alloplastic implant, injuring surrounding nerves, cost of procedure and long recovery times. Complications can also occur from inadequate engineering of alloplastic implants and grafts, and poor implant fixation to bone. These include infection, inflammatory reactions, the fracture of alloplastic implants and prostheses, loosening of implants or reduced or complete loss of osseointegration.
Transvaginal mesh, also known as vaginal mesh implant, is a net-like surgical tool that is used to treat pelvic organ prolapse (POP) and stress urinary incontinence (SUI) among female patients. The surgical mesh is placed transvaginally to reconstruct weakened pelvic muscle walls and to support the urethra or bladder.
A surgical site infection (SSI) develop when bacteria infiltrate the body through surgical incisions. These bacteria may come from the patient's own skin, the surgical instruments, or the environment in which the procedure is performed.
