What is exploratory laparotomy?

An exploratory laparotomy is a type of surgical procedure used to evaluate the condition of the internal organs in the abdominal area.

What Is an Exploratory Laparotomy?

An exploratory laparotomy is performed when other types of tests have been insufficient to establish a diagnosis. It can also be used to take a biopsy or to repair and remove a damaged part of an organ or tissue.

When a diagnostic laparoscopy is contraindicated, an exploratory laparotomy is used, or when there are signs of certain specific conditions.

This is a procedure that is usually scheduled when other studies have not been conclusive, although it can also be performed urgently in situations like an acute abdomen.

Exploratory Laparotomy Procedure

An exploratory laparotomy is a major surgical procedure performed under general anesthesia. It consists of opening the abdomen through an incision that can vary in size and location, depending on the area that needs to be explored.

Once the abdominal cavity is opened, the surgeon will systematically examine the internal organs such as the stomach, intestines, spleen, pancreas, or liver. This will allow for the identification of injuries, infections, bleeding, or the presence of abnormal masses.

During the procedure, if the cause of the problem is detected, the surgeon can correct it on the spot, for example, by removing a mass, repairing a perforated organ, or draining abscesses.

Additionally, a peritoneal lavage may be performed. The incision is then closed with sutures or staples, and if necessary, drains are left to facilitate the exit of fluids. After the procedure and throughout the first week, the person may experience nausea and some pain in the area where the incision was made. Depending on what was done during the surgery, the patient can return to their normal life in a few days or even weeks.

It is important to check the surgical wound daily for healing and to follow the doctor’s recommendations to avoid possible infections.

Risks of an Exploratory Laparotomy

Like any surgical procedure, an exploratory laparotomy is not without some risks during the surgery and in the postoperative period.

One of the main risks is hemorrhage, since exploring the abdomen may require manipulating or cutting vascular tissues. There is also the risk of accidental injury to internal organs, especially in cases where there is inflammation or adhesions.

Another important risk is the development of infections, which can occur both in the surgical wound and at the intra-abdominal level, leading to the development of abscesses or peritonitis.

It is also possible to have complications such as the formation of fistulas, hernias at the incision site, or problems with tissue healing, especially in patients with chronic diseases such as immunosuppression or diabetes.

An exploratory laparotomy can also be associated with anesthetic risks and respiratory, cardiovascular, or thromboembolic complications, especially in elderly patients or those with pre-existing diseases.

Despite the above, in general, an exploratory laparotomy is a safe procedure when performed under clear medical indications and in an appropriate hospital setting. Its safety level will largely depend on the patient’s general health, the underlying cause for the procedure, and the experience of the surgical team.

Although risks exist, many complications are preventable or can be treated effectively with proper management before, during, and after the surgery.

Abdominal Exploration

An exploratory laparotomy is a surgical procedure indicated when there are clinical signs of a serious abdominal pathology that cannot be accurately diagnosed through imaging or laboratory studies, or when immediate intervention is necessary.

Some of the most frequent causes that require this abdominal exploration are:

• Acute abdomen of uncertain origin: Especially if it is accompanied by intense pain, abdominal distention, or signs of peritoneal irritation without a clear diagnosis.
• Intra-abdominal hemorrhage: Regardless of whether it is caused by blunt or penetrating trauma, or by the rupture of an organ such as the spleen, liver, or a ruptured ectopic pregnancy.
• Generalized peritonitis: Caused by the perforation of a hollow viscus, such as a perforated gastric ulcer, complicated appendicitis, or perforated diverticulitis.
• Intestinal obstruction: In cases where the obstruction is not resolved with conservative treatment or where strangulation or intestinal ischemia is suspected.
• Tumors or masses: In the presence of abdominal tumors or masses of unknown etiology that require a biopsy or resection.
• Postoperative complications: There may be internal bleeding or dehiscence of sutures that may require a new intervention for revision or correction.
