Last updated: 02/17/2009
The patient is usually placed under general anesthesia for the duration of surgery. The advantages to general anesthesia are that the patient remains unconscious during the procedure, no pain will be experienced nor will the patient have any memory...
of the procedure, and the patient's muscles remain completely relaxed, allowing safer surgery.
Incision
Once an adequate level of anesthesia has been reached, the initial incision into the skin may be made. A scalpel is first used to cut into the superficial layers of the skin. The incision may be median (vertical down the patient's midline), paramedian (vertical elsewhere on the abdomen), transverse (horizontal), T-shaped, or curved, according to the needs of the surgery. The incision is then continued through the subcutaneous fat, the abdominal muscles, and finally, the peritoneum. Electrocautery is often used to cut through the subcutaneous tissue as it has the ability to stop bleeding as it cuts. Instruments called retractors may be used to hold the incision open once the abdominal cavity has been exposed.
Abdominal exploration
The surgeon may then explore the abdominal cavity for disease or trauma. The abdominal organs in question will be examined for evidence of infection, inflammation, perforation, abnormal growths, or other conditions. Any fluid surrounding the abdominal organs will be inspected; the presence of blood, bile, or other fluids may indicate specific diseases or injuries. In some cases, an abnormal smell encountered upon entering the abdominal cavity may be evidence of infection or a perforated gastrointestinal organ.
If an abnormality is found, the surgeon has the option of treating the patient before closing the wound or initiating treatment after exploratory surgery. Alternatively, samples of various tissues and/or fluids may be removed for further analysis. For example, if cancer is suspected, biopsies may be obtained so that the tissues can be examined microscopically for evidence of abnormal cells. If no abnormality is found, or if immediate treatment is not needed, the incision may be closed without performing any further surgical procedures.
During exploratory laparotomy for cancer, a pelvic washing may be performed; sterile fluid is instilled into the abdominal cavity and washed around the abdominal organs, then withdrawn and analyzed for the presence of abnormal cells. This may indicate that a cancer has begun to spread (metastasize).
Closure
Upon completion of any exploration or procedures, the organs and related structures are returned to their normal anatomical position. The incision may then be sutured (stitched closed). The layers of the abdominal wall are sutured in reverse order, and the skin incision closed with sutures or staples.

Other Information
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.
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.

Biliary colic is the presenting symptom in 80% of patients with gallstone disease who seek medical care; however, only 10-20% of all individuals with gallstones experience severe gallstone pain.
