Subject of operative surgery
Operative surgery is based on a comprehensive study of the surgical operation. This discipline does not merely describe the course of interventions, but represents a cohesive doctrine. Its main task is the development of new and improvement of existing methods of surgical work, as well as establishing strict rules according to which these interventions must be performed to ensure patient safety and health.
What is a surgical operation
The term originates from the Latin word operatio, which translates as "work" or "action".
In the classical sense, a surgical operation is a direct mechanical action by a physician on a patient's tissues and organs. Such an action always has a clear purpose: it is performed either to treat a disease or to conduct complex diagnostics.
Any classical operation has a strict logical essence and consists of three consecutive stages:
- Tissue dissection — necessary to gain access and expose the diseased organ.
- Manipulation — the main therapeutic or diagnostic stage performed on the organ itself.
- Tissue closure — restoration of tissue integrity after the work is completed.
Surgical nomenclature
To ensure physicians can understand each other without unnecessary words, a strict nomenclature was developed. The name of any operation is formed following a constructor-like principle: Name of the operated organ + Name of the performed action.
The action within the term is indicated by special suffixes. In general surgery, three main suffix terms are distinguished:
- -tomy (-tomia) — denotes a simple incision of an organ or opening of its lumen. Used when the organ needs to be opened, but not removed.
Examples: gastrotomy, enterotomy, choledochotomy.
- -ectomy (-ectomia) — denotes the complete removal of an organ.
Examples: appendectomy, gastrectomy.
- -stomy (-stomia) — implies the creation of an artificial communication (fistula) between the internal organ cavity and the external environment.
Examples: tracheostomy, cystostomy.
Briefly: answers to topical questions
How are surgical operations classified by urgency?
By urgency of performance, surgical operations are classified into emergency, urgent, and elective.
- Emergency operations — performed immediately or within the first hours after patient admission for life-threatening conditions.
- Urgent operations — performed within the first days after admission when short-term preparation or diagnostic clarification is required.
- Elective operations — performed electively; their timing is not restricted since the patient's life is not currently under threat.
What are the types of therapeutic surgical operations based on the degree of removal of the pathological focus?
Based on the possibility of complete cure (radicalism), surgical operations are divided into radical and palliative.
- Radical operations — removal of the tumor en bloc with regional lymph nodes, fascia, and adipose tissue.
- Palliative operations — creation of a fecal fistula (artificial anus) on the sigmoid colon.
To avoid confusing the terms, remember the association: "-TOMY" — only Trauma (cutting), "-ECTOMY" — Evacuation (removing the organ entirely), "-STOMY" — Stoma creation (connection with the environment).
Class and exam questions
What does the term "operation" mean in translation from Latin?
The word operatio translates from Latin as "work" or "action".
What mandatory stages constitute the essence of any surgical intervention?
The essence of an operation comes down to three steps: first, tissues are dissected to expose the organ, then a therapeutic or diagnostic manipulation is performed, and finally, the tissues are closed.
What is the fundamental difference between terms with the suffixes -tomy and -ectomy?
The suffix -tomy means only the incision of an organ and opening of its lumen (e.g., for inspection), whereas -ectomy implies the complete removal of that organ from the body.
