Surgeons may recommend diagnostic laparoscopy when patients present with unidentified abdominal issues.

What is Diagnostic Laparoscopy?

Diagnostic laparoscopy involves the utilization of a specialized medical instrument known as a laparoscope. This device is equipped with a high-intensity light source and interfaces with a high-resolution monitor. To enable visualization of the abdominal interior, a hollow tube (referred to as a port) is inserted through the abdominal wall, through which the laparoscope is introduced. The resulting imagery of the abdominal cavity is projected onto the monitor. In the majority of cases, this surgical procedure serves the purpose of diagnosing or assisting in the identification of underlying abdominal conditions.

Common Uses of Diagnostic Laparoscopy:

Addressing Abdominal Pain: Diagnostic laparoscopy plays a crucial role in evaluating both acute and chronic abdominal pain, which can have various underlying causes. Some of these causes encompass conditions like appendicitis, intra-abdominal adhesions or scar tissue, pelvic infections, endometriosis, abdominal bleeding, and, albeit less frequently, cancer. Additionally, it is employed in cases of irritable bowel disease to rule out alternative sources of abdominal pain. During this procedure, surgeons often identify the root cause of the abdominal pain and, if feasible, address it within the same surgical session.

Managing Abdominal Masses: Patients may present with palpable lumps or tumors, which can be detected by physicians, patients themselves, or through X-ray imaging. In many instances, these masses necessitate a definitive diagnosis before appropriate treatment can be prescribed. Diagnostic laparoscopy serves as a valuable technique for physicians to directly inspect these masses and obtain tissue samples for accurate diagnosis.

Investigating Ascites: Ascites refers to the accumulation of fluid within the abdominal cavity. At times, the cause of this fluid buildup remains elusive without a thorough examination of the abdominal cavity, a task that diagnostic laparoscopy can effectively accomplish.

Evaluating Liver Disease: Non-invasive imaging methods such as ultrasound, CT scan, and MRI can detect masses within or on the surface of the liver. However, when these imaging techniques do not provide sufficient diagnostic information, a liver biopsy may be required to establish a definitive diagnosis. Diagnostic laparoscopy is considered one of the safest and most precise methods to obtain tissue samples for diagnosis. Essentially, it offers a high degree of accuracy in collecting liver or mass biopsies without the need for open abdominal surgery.

Cancer Staging: Physicians may require detailed information about the status of a previously treated disease, particularly in cases of cancer. This necessity can arise after certain forms of chemotherapy or before initiating further chemotherapy. Diagnostic laparoscopy can also furnish crucial insights before planning extensive abdominal exploration, chemotherapy, or radiation therapy.

Other Indications: Diagnostic laparoscopy may be indicated for various other reasons, which cannot all be exhaustively listed here. It is advisable to review and discuss these specific indications with your surgeon for a comprehensive understanding of your unique case.

Preparation for the Procedure:

Required Diagnostic Tests:

Ultrasound: Your doctor may order an ultrasound as a non-invasive diagnostic test. In many instances, this test provides valuable information that enhances your surgeon's understanding of the abdominal issue. It is worth noting that ultrasounds are not painful, pose minimal risks, and can significantly contribute to the diagnostic process, potentially reducing the need for further invasive procedures.
CT Scan (Computed Tomography): This imaging technique employs X-rays and computer technology to visualize the contents of the abdominal cavity. In specific situations, a CT scan can accurately diagnose abdominal diseases. It serves as a sort of "road map" for your surgeon, offering a detailed view of the internal abdominal structures. In some cases, a radiologist may utilize a CT scan to guide the placement of a needle within the abdomen, a procedure known as CT-guided needle biopsy. This step is often taken prior to diagnostic laparoscopy to determine its suitability for your condition.
MRI (Magnetic Resonance Imaging): MRI employs magnetic fields and computer processing to create detailed images of the abdominal cavity's interior. While it is not necessary for most abdominal issues, there may be situations where an MRI is deemed essential for diagnosis.

Routine Laboratory Tests:

Routine blood tests, urinalysis, and, in certain cases, a chest X-ray or electrocardiogram may be required as part of the preoperative assessment before undergoing diagnostic laparoscopy. Your physician will carefully determine which tests are necessary based on your specific medical history and condition. The results of any previously conducted tests will also be reviewed.

Anaesthesia Options:

General Anaesthesia: Diagnostic laparoscopy is typically performed under general anaesthesia, which ensures that you are completely unconscious during the procedure. Collaboratively with your surgeon and an anaesthesiologist, the most appropriate anaesthesia method will be selected to ensure the safety and success of the surgery.
Local Anaesthesia with Sedation: In select cases, diagnostic laparoscopy can be carried out under local anaesthesia with sedation. This involves injecting local anaesthesia into the abdominal wall skin to numb the area and facilitate the safe insertion of a laparoscope. Patients may experience a brief "bee sting" sensation lasting a second or two. Concurrently, small doses of intravenous sedation are administered, inducing a state known as "twilight" sleep, in which patients are somewhat responsive but asleep. Once an adequate level of sedation is achieved and local anaesthesia is administered, gas is introduced into the abdominal cavity (pneumoperitoneum), causing a bloated sensation. The gas is expelled at the conclusion of the operation. Nitrous oxide or carbon dioxide are the two most commonly used gases, and they pose minimal risk of adverse effects.
General Anaesthesia: For patients who are not suitable candidates for "twilight" sleep or prefer to be entirely unconscious during the procedure, general anaesthesia is administered. It is often preferred for younger patients, individuals unable to remain still on the operating table, or those with medical conditions that make this anesthesia method safer. Occasionally, patients may receive general anaesthesia even if they initially preferred local anaesthesia with sedation, as the choice of anaesthesia for laparoscopy is tailored to each patient's unique circumstances.

Preparation Requirements:

Informed Consent: After a thorough discussion with your surgeon regarding the potential risks and benefits associated with the procedure, you will be required to provide written consent for the surgery. This step ensures that you are well-informed and have agreed to proceed with the operation.
Outpatient Procedure: The majority of diagnostic laparoscopy procedures are conducted on an outpatient basis, meaning you will be discharged on the same day as the procedure.
Fasting: It is essential to refrain from eating or drinking for a specified duration before the procedure. The specific fasting period will be determined by your surgeon and anesthesiologist to ensure your safety during the surgery.
Preoperative Testing: Depending on your age and medical condition, standard preoperative tests such as blood tests, urine analysis, or X-rays may be required. These tests aim to assess your overall health and suitability for the surgical procedure.
Hygiene: You are encouraged to take a shower either the night before or on the morning of the operation to maintain cleanliness.
Hospital Arrival: Arrive at the hospital at the designated time, typically 1-2 hours prior to your scheduled surgery.
Medication Management: If you take daily medications, it is crucial to discuss this with your surgeon before the surgery. You may receive guidance on whether to take some or all of your regular medications on the day of surgery with a small sip of water. Special attention should be given to medications such as aspirin, Vitamin E, blood thinners, or arthritis medications, as your surgeon may recommend discontinuing them at an appropriate time before the surgery.
Clarify Requirements: To ensure you are fully prepared, it is advisable to consult with your surgeon or their office staff regarding the specific preparations needed for your surgery.
Post-Procedure Transportation: Since you are likely to be sedated during the procedure, arranging for someone to drive you home afterward is mandatory. Sedatives can affect your judgment and reflexes for the remainder of the day, making it unsafe for you to operate a vehicle or machinery until the following day.

Procedure Overview:

Anesthesia: The surgery is conducted under anesthesia, as mentioned earlier, to ensure that you do not experience pain during the procedure.
Port Placement: A narrow tube-like instrument known as a "port" is carefully inserted into the abdominal cavity. This port is typically positioned in the upper abdomen or flank, just below the ribcage.
Laparoscope: Through the inserted port, a tiny telescope called a "laparoscope" is introduced. This laparoscope is connected to a specialized camera, providing the surgeon with a magnified and detailed view of the patient's internal organs. The images captured by the laparoscope are displayed on a television screen in the operating room.
Additional Ports: In addition to the initial port, other ports may be inserted as needed. These additional ports enable your surgeon to further examine the internal organs and make informed decisions regarding diagnosis or treatment.
Closure of Incisions: Once the surgical procedure is completed, the small incisions made for port insertion are closed. This can be achieved using absorbable sutures or surgical tapes, depending on the surgeon's preference and the specific case.

Post-Surgery Expectations and Guidelines

Recovery Room Monitoring:
- You will be transferred to the recovery room.
- Close monitoring until the effects of sedatives and anaesthetics have worn off.
- Lingering effects of anesthesia can persist for hours.
- Discharge once you can walk and get out of bed unassisted.
- A companion is required to accompany you for transportation due to anaesthesia effects.

Soreness and Pain:

- Expect soreness around incision sites (normal).
