AskDefine | Define laparotomy

Dictionary Definition

laparotomy n : surgical incision into the abdominal wall; often done to examine abdominal organs

Extensive Definition

A laparotomy is a surgical procedure involving an incision through the abdominal wall to gain access into the abdominal cavity. It is also known as coeliotomy.

Terminology

In diagnostic laparotomy (most often referred to as an exploratory laparotomy and abbreviated Ex-Lap), the nature of the disease is unknown, and laparotomy is deemed the best way to identify the cause.
In therapeutic laparotomy, a cause has been identified (e.g. peptic ulcer, colon cancer) and laparotomy is required for its therapy.
Usually, only exploratory laparotomy is referred to as a surgical operation by itself; and when a specific operation is already planned, laparotomy is considered merely the first step of the procedure.

Spaces accessed

Depending on incision placement, it may give access to any abdominal organ or space, and is the first step in any major diagnostic or therapeutic surgical procedure of these organs, which include:

Types of incisions

Midline

The most common incision for laparotomy is the midline incision, a vertical incision which follows the linea alba.
Midline incisions are particularly favoured in diagnostic laparotomy, as they allow wide access to most of the abdominal cavity.

Other

Other common laparotomy incisions include:
  • the Davis or Rockey-Davis "muscle-splitting" right lower quadrant incision for appendectomy;
  • Lumbotomy consists of a lumbar incision which permits access to the kidneys (which are retroperitoneal) without entering the peritoneal cavity. It is typically used only for benign renal lesions. It has also been proposed for surgery of the upper urological tract.

Related procedures

A related procedure is laparoscopy, where cameras and other instruments are inserted into the peritoneal cavity via small holes in the abdomen. For example, an appendectomy can be done either by a laparotomy or by a laparoscopic approach.
