Surgery is a procedure that involves
cutting of a patient's tissues or closure of a
previously sustained wound.

Surgery is defined as the treatment of
injuries or disorders of the body by
incision or manipulation, especially with
instruments.

General surgery
• General Surgery is a medical discipline
that involves performing various types of
surgical procedures to treat a broad
range of health problems and diseases.
• These include bile ducts, liver, pancreas,
spleen, appendix, small and large
intestine, rectum, and the stomach etc.
Surgical procedures are
classified based On
1.Urgency
2.Risk
3.Purpose
1.Elective surgery
2.Urgent surgery
3.Emergency surgery
• It is a procedure that is pre planned
and based on patients choice and
availability of scheduling for the
patient, surgeon and the facility.
• Delay of surgery has no ill effects.
Examples are…
Hernia repair
Cataract extraction
Tonsillectomy
Hip prosthesis
• Must be done with in a reasonably
short time frame to preserve health.
Usually done with in 24 – 48 hours.
• Examples are…
 Removal of gall bladder
Amputation
Appendectomy
• Must be done immediately to
preserve life, a body part or
function.
• Examples are…
Control of haemorrhage
Repair of trauma ,perforated
ulcers , intestinal obstruction..
1.Major surgery
2.Minor surgery
• Major surgery requires
hospitalization and specialized
care, is usually prolonged, has a
higher degree of risk, involves
major body organs or life
threatening situations, and has a
greater risk for postoperative
complications.
• Examples are…
 Open Cholecystectomy
 Nephrectomy
 Hysterectomy
 Radical mastectomy
 Laparotomy
• Minor surgery is usually brief,
carries a low risk and results
in few complications. Minor
surgeries are mostly elective.
• Examples are…
Teeth extraction
Cataract extraction
1.Diagnostic
2.Ablative
3.Palliative (Intestinal Obst)
4.Reconstructive
5.Transplantation
6.Constructive
Surgeries to make or confirm a
diagnosis.
•Examples are…
 Biopsy
 Bronchoscopy
 Endoscopy
• Surgeries To remove
a diseased body
part.
•Examples are…
Appendectomy
Amputation
• Surgeries to relieve or reduce
intensity of an illness.
• It is not curative.
•Examples are…
Colostomy
Nerve root resection
• Surgeries to restore function to
traumatized or malfunctioning
tissue or to improve self concept.
Examples are…
Scar revision
Plastic surgery
Internal fixation of a fracture
Breast reconstruction
• Surgeries to replace organs
or structures that are
diseased or malfunctioning
• Examples are…
 Kidney, liver, heart
transplantation.
• Surgeries To restore functions
in congenital anomalies.
• Examples are…
Cleft lip Repair
Closure of Atrial Septal Defect

Editor's Notes

  • #13 Radical mastectomy is a surgical procedure involving the removal of breast, underlying chest muscle (including pectoralis major and pectoralis minor), and lymph nodes of the axilla as a treatment for breast cancer.
  • #24 Ileus is the medical term for this lack of movement somewhere in the intestines that leads to a buildup and potential blockage of food material. An ileus can lead to an intestinal obstruction. This means no food material, gas, or liquids can get through. It can occur as a side effect after surgery.
  • #25 breast augmentation  also known as augmentation mammoplasty A breast implant is a prosthesis used to change the size, shape, and contour of a person's breast. In reconstructive plastic surgery, breast implants can be placed to restore a natural looking breast . Functional abdominal pain (FAP) „negative” appendectomy
