SpecialtyGeneral surgery

A laparotomy is a surgical procedure involving a large incision through the abdominal wall to gain access into the abdominal cavity. It is also known as a celiotomy. The first successful laparotomy was performed without anesthesia by Ephraim McDowell in 1809 in Danville, Kentucky.


The term arises from the Greek word λᾰπάρᾱ ("lapara"), meaning "the soft part of the body between the ribs and hip, flank,"[1] and the suffix "-tomy" arising from the Greek word "τομή" meaning "a (surgical) cut."

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. colon cancer) and the operation is required for its therapy.

Usually, only exploratory laparotomy is considered a stand-alone surgical operation. When a specific operation is already planned, laparotomy is considered merely the first step of the procedure.

Spaces accessed[edit]

Depending on incision placement, laparotomy 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[edit]


The most common incision for laparotomy a vertical incision in the middle of the abdomen which follows the linea alba.

  • The upper midline incision usually extends from the xiphoid process to the umbilicus.
  • A typical lower midline incision is limited by the umbilicus superiorly and by the pubic symphysis inferiorly.
  • Sometimes a single incision extending from xiphoid process to pubic symphysis is employed, especially in trauma surgery.

Midline incisions are particularly favoured in diagnostic laparotomy, as they allow wide access to most of the abdominal cavity.

Midline incision[edit]

  1. Cut (incised) the skin in midline (linea alba)
  2. Cut (incised) subcutaneous tissue
  3. Divide the linea alba (white line of the abdomen)
  4. Pick up peritoneum, confirm that there is no bowel adhesion (intestinal adhesion)
  5. Nick peritoneum
  6. Insert finger beneath the wound to make sure that there is no adhesion
  7. Cut the peritoneum with scissors


Other common laparotomy incisions include:

  • Kocher (right subcostal) incision (after Emil Theodor Kocher); appropriate for certain operations on the liver, gallbladder and biliary tract.[2] This shares a name with the Kocher incision used for thyroid surgery: a transverse, slightly curved incision about 2 cm above the sternoclavicular joints;
  • Davis or Rockey-Davis "muscle-splitting" right lower quadrant incision for appendectomy, named for the Oregon surgeon, Alpha Eugene Rockey (1857–1927) and the Philadelphia surgeon, Gwilym George Davis (1857–1918), who devised such incision style in 1905.[3]
  • Pfannenstiel incision, a transverse incision below the umbilicus and just above the pubic symphysis.[4][5] In the classic Pfannenstiel incision, the skin and subcutaneous tissue are incised transversally, but the linea alba is opened vertically. It is the incision of choice for Cesarean section and for abdominal hysterectomy for benign disease. A variation of this incision is the Maylard incision in which the rectus abdominis muscles are sectioned transversally to permit wider access to the pelvis.[6] This was pioneered by the Scottish surgeon, Alfred Ernest Maylard (1855–1947) in 1920.[7]
  • 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.[8]
  • Cherney Incision – developed in 1941 by the American uro-gynecologic surgeon, Leonid Sergius Cherney (1908–1963)[9]

Complications following laparotomy[edit]

Globally, there are few studies comparing perioperative mortality following laparotomy across different health systems. One major prospective study of 10,745 adult patients undergoing emergency laparotomy from 357 centres in 58 high-, middle-, and low-income countries found that mortality is three times higher in low- compared with high-HDI countries even when adjusted for prognostic factors.[10] In this study the overall global mortality rate was 1.6 percent at 24 hours (high 1.1 percent, middle 1.9 percent, low 3.4 percent; P < 0.001), increasing to 5.4 percent by 30 days (high 4.5 percent, middle 6.0 percent, low 8.6 percent; P < 0.001). Of the 578 patients who died, 404 (69.9 percent) did so between 24 h and 30 days following surgery (high 74.2 percent, middle 68.8 percent, low 60.5 percent). Patient safety factors were suggested to play an important role, with use of the WHO Surgical Safety Checklist associated with reduced mortality at 30 days.

Taking a similar approach, a unique global study of 1,409 children undergoing emergency laparotomy from 253 centres in 43 countries showed that adjusted mortality in children following surgery may be as high as 7 times greater in low-HDI and middle-HDI countries compared with high-HDI countries, translating to 40 excess deaths per 1000 procedures performed in these settings. Internationally, the most common operations performed were appendectomy, small bowel resection, pyloromyotomy and correction of intussusception. After adjustment for patient and hospital risk factors, child mortality at 30 days was significantly higher in low-HDI (adjusted OR 7.14 (95% CI 2.52 to 20.23), p<0.001) and middle-HDI (4.42 (1.44 to 13.56), p=0.009) countries compared with high-HDI countries.[11]

Related procedures[edit]

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.
