Types of wounds
Types of wounds

  • Cut wounds incised

  • Lacerated wounds

  • Crushed wounds

  • Wounds with skin loss


Types of suturing
Types of Suturing

  • Primary suturing

  • Excision and primary suturing

  • Delayed primary suturing

  • Secondary suturing

  • Skin grafting


Elements of wound healing
Elements of Wound Healing

1- Contraction

2- Connective tissue formation (granulation tissue)

3- Epithelization


Surgical wounds
Surgical Wounds

Clean

Clean contaminated

Contaminated

Dirty


Factors which affect wound healing
Factors which affect wound healing

General: Malnutrition, ureamia, malignancy, radiothempy, cytotoxic drugs, duabetes, vitc deficiency.

Local Factors:

- Blood supply

- Tension in wound

- presence of necrotic tissue and F.B

- presence of haematoma

- excessive cauterization, rough manipulation

- infection



Principles of wound management
Principles of wound management

Correct all local and systemic factors that might impair wound healing

Wound toilet

Wound dressing

Antibiotics if infected



  • Ulcers are non-healing wounds that develop on the skin, mucous membranes or eye. Although they have many causes, they are marked by:

  • Loss of integrity of the area

  • Secondary infection of the site by bacteria, fungus or virus

  • Generalized weakness of the patient

  • Delayed healing


Location
Location mucous membranes or eye. Although they have many causes, they are marked by:

  • Lower limbs: most ulcers of the foot and leg are caused by underlying vascular insufficiency . The skin breaks down or fails to heal because of repeated insult or trauma.

  • Sacrum and ischium

  • Mouth ulcer


Cont… mucous membranes or eye. Although they have many causes, they are marked by:

4. Peptic ulcer: This includes ulcers of the esophagus, stomach, large and small intestine

  • Genitalia: May be penile, vulvar or labial. Most often are due to sexually-transmitted disease.

  • Eyes: corneal ulcers are the most common type. Conjunctival ulcers also occur.


Causes
causes mucous membranes or eye. Although they have many causes, they are marked by:

Bacterial , viral & fungal infection

Cancer both primary & secondary

Venous stasis

Arterial insufficiency

Diabetes

Rheumatoid arthritis

Loss of mobility


Description
Description mucous membranes or eye. Although they have many causes, they are marked by:

Site

Size

Shape

Base

Edge

Tenderness

Discharge

Surrounding tissue & lymphatics


Types
Types mucous membranes or eye. Although they have many causes, they are marked by:

Peptic ulcer

Mouth ulcer

Pressure ulcer (decubitus)

Arterial insufficiency ulcer

Venous insufficiency ulcer

Diabetic foot ulcer


Ischaemic ulceration
Ischaemic ulceration mucous membranes or eye. Although they have many causes, they are marked by:

By definition caused by inadequate blood supply “large \ small artery obliteration”

In elderly , who also have symptoms of coronary vascular disease.

Men predominate

Risk factor – Smoking, atherosclerosis

Very painful, causes rest pain

Do not bleed but discharge thin serous exudates which can become purulent

Distal pulses are impalpable


Neuropathic ulceration
Neuropathic ulceration mucous membranes or eye. Although they have many causes, they are marked by:

Deep penetrating ulcer which occur over pressure point, but the surrounding tissue are healthy and have good circulation.

Diagnostic features:-

1- painless

2- surrounding tissues are unable to appreciate pain

3- surrounding tissues have normal blood supply


Cont … mucous membranes or eye. Although they have many causes, they are marked by:

  • Causes:-

  • peripheral nerve lesions “diabetes ,nerve injuries”

  • Spinal cord lesions “spina bifida,tabes dorsalis”


Venous ulceration
Venous ulceration mucous membranes or eye. Although they have many causes, they are marked by:

Follow many year of venous disease.

Commonly occur on the medial side of the leg above the ankle

Predominantly in women

Risk factor – Varicose veins

Pulses are normal


Fistulas

Fistulas mucous membranes or eye. Although they have many causes, they are marked by:


Definition
Definition mucous membranes or eye. Although they have many causes, they are marked by:

Fistulas is an abnormal communication between two epithelial or endothelial surfaces


Types of fistula
Types of fistula mucous membranes or eye. Although they have many causes, they are marked by:


Why do they occur
Why do they occur? mucous membranes or eye. Although they have many causes, they are marked by:

Some are congenital e.g. Tracheooesophageal fistula

Internal abdominal fistulas :Majority result from an underlying gastro-

intestinal disease ( e.g. colonic diverticular disease, crohn’s disease, colonic carcinoma, etc )


External abdominal fistulas arise as a complication of surgery or to the trauma.

Other external fistulas are due to primary abscess formation and rupture on to skin. E.g. perianal fistula


Management
Management surgery or to the trauma.

Difficult to treat

Is complex and usually surgical

Depend on the site of the fistula


Treatment
Treatment surgery or to the trauma.

Conservative :

The mainstays of medical management are:

- nutritional support

- meticulous collection of fistulous discharge

- skin-stoma care

- control of sepsis


Surgical : surgery or to the trauma.

The absolute indications for operative intervention are :

- intestinal distal obstruction

- peritonitis

- abscess formation

- bowel discontinuity

- presence of malignant disease

- persistent inflammatory bowel disease


Cysts

Cysts surgery or to the trauma.


What is a cyst
What is a cyst? surgery or to the trauma.

a cyst is : any closed epithelium-lined cavity or sac, normal or abnormal, usually containing liquid or semisolid material" (Dorland's, 1995, pp.209).

It is common can occur anywhere any age.

Cysts vary in size

Its wall called the cyst capsule


What are the causes of a cyst
What are the causes of a cyst? surgery or to the trauma.

Cysts are usually formed through one of these mechanisms:

Obstructions to the flow of fluid

Infections and chronic inflammations

Tumors

Genetic (inherited) conditions

Defects in developing organs in the embryo


Examples of cysts
Examples of cysts surgery or to the trauma.

Thyroglossal cyst

Ovarian cyst

Sebaceous cyst


Treatment1
Treatment surgery or to the trauma.

Usually surgical - Cystectomy
