Definition & Overview
Laparoscopy is a surgical technique in which a thin fibre optic cable system is passed through small cuts in the skin to gain access to the target surgical site without making a big skin incision, as is required in a traditional open surgery. This technique is performed using a video camera that delivers visuals of the surgical site to a television monitor that the surgeon uses as a guide. Due to this, all procedures performed using laparoscopy are referred to as “minimally invasive” or “keyhole surgery.”
Laparoscopic surgery has significantly been developed since it was first introduced in the early 1990s. It is now considered as the standard technique for many surgical procedures and is being used for a number of more complex surgeries. Its popularity is mainly due to its several benefits, such as less pain, reduced bleeding during and after the procedure, and shorter recovery downtime, among others.
Who Should Undergo and Expected Results
Laparoscopic surgery can be recommended to those who:
- Wish to avoid major risks associated with traditional open surgery
- Only require simple procedures that do not justify an open surgery
- Have existing medical conditions that make an open surgery risky
- Require a diagnostic examination of the internal organs and/or a biopsy
The indications for minimally invasive keyhole surgery, both as a diagnostic and therapeutic procedure, are steadily increasing in number as the technology further advances. This is especially true in the field of abdominal and gastrointestinal procedures.
Laparoscopic procedures offer the following key benefits:
- Reduced pain and less pain medication necessary
- Reduced bleeding during and after the procedure
- Reduced risk of haemorrhage
- Shorter hospital stay
- Shorter recovery downtime
- Lower risk of post-surgical complications
- Minimal post-surgical scarring
In the field of diagnostic medicine, laparoscopy is used to diagnose a number of serious diseases, such as:
- Fluid retention in the abdominal cavity
- Cancer staging
- Liver disease
- Inflammation of the intestines
- Pelvic inflammatory disease
Despite these benefits, there are some situations wherein a laparoscopic procedure is not appropriate, such as in the case of paediatric surgery. In addition, it is associated with some disadvantages, including:
- Reduced dexterity and limited range of motion at the surgical site
- Greater risk of intra-abdominal abscess
- Reduced tactile sensation, which increases the risk of tissue damage
- Limited view of the surgical site, which may limit the surgeon’s ability to adequately assess and address the condition
Despite these disadvantages, keyhole surgery still marks a significant development in the field of surgery. In order to avoid its disadvantages, the technique is currently being used in simpler procedures, while open surgery remains as the primary technique for more complicated surgical cases.
How is the Procedure Performed?
Laparoscopic surgery is usually performed as an outpatient procedure and under either general or local anaesthesia, depending on the scope of the surgery and the severity of the condition.
Laparoscopic surgery gives a surgeon access to the internal organs using a number of small incisions, usually 0.5 to 1.5 cm in size, and a special instrument called a laparoscope, a tube with a high-resolution camera and a light strobe attached to it. The incisions are usually made below the belly button for abdominal surgeries. The camera captures real-time images of the internal organs and sends it to a video monitor to give the surgeon visual guidance throughout the procedure. This allows the surgeon to see and perform surgeries inside a patient’s body without resorting to open surgery.
If necessary, the patient’s abdomen is also inflated using carbon dioxide gas passed through a small tube (cannula) to get better visuals of the abdominal organs.
After the procedure, the surgeon will close up the incisions with stitches or surgical tape and then apply a sterile dressing for protection. Although the stitches are very minimal, they may still cause mild to moderate pain or discomfort during the first few days after surgery. Patients can expect to be able to resume normal activities within a week after the procedure. Surgeons typically schedule a follow-up visit after two weeks to ensure that the patient is recovering well.
Possible Risks and Complications
Laparoscopic surgery is not without risks, with bleeding and infection being the most common. However, they occur less frequently when compared to open surgeries. Other risks and their possible symptoms, include:
- Stomach pain
- Drainage at the sites of the incisions
- Allergic reaction to the anaesthesia used

## What is Laparoscopic Surgery? Overview, Benefits, and Expected Results
**Laparoscopic Surgery: An Overview**
Laparoscopic surgery, also known as minimally invasive surgery (MIS), is a surgical technique that allows surgeons to access the abdominal and pelvic cavities through small incisions in the abdomen. Instead of making a large incision, surgeons insert a laparoscope, a slender tube with a camera attached, into the abdomen. The camera sends images of the inside of the abdomen to a monitor, allowing the surgeon to see the organs and tissues in detail. Surgical instruments are then inserted through additional small incisions to perform the necessary procedures.
### Benefits of Laparoscopic Surgery:
1. **Minimal Invasive**: Laparoscopic surgery results in smaller incisions, leading to reduced pain and scarring.
2. **Faster Recovery**: Patients generally recover faster from laparoscopic surgery compared to traditional open surgery, resulting in a shorter hospital stay and quicker return to daily activities.
3. **Reduced Risk of Infection**: Minimally invasive surgery has a lower risk of infection due to the smaller incisions.
4. **Less Tissue Damage**: As laparoscopic procedures use smaller instruments, it results in less tissue damage and less post-operative discomfort.
5. **Improved Visualization**: The laparoscope’s high-resolution camera provides a magnified view of the surgical site, enabling better visualization and more precise dissection.
6. **Cosmetically Pleasing**: The small incisions made during laparoscopic surgery leave less visible scars, resulting in a more cosmetically pleasing outcome.
### Expected Results of Laparoscopic Surgery:
1. **Success Rate**: The success rate of laparoscopic surgery is comparable to that of traditional open surgery.
2. **Complications**: Laparoscopic surgery has a lower risk of complications such as bleeding, infection, and blood clots compared to traditional surgery.
3. **Reduced Hospital Stay**: Patients generally experience a shorter hospital stay (often just a few days) after laparoscopic surgery, leading to lower medical costs.
4. **Faster Recovery**: As laparoscopic procedures are typically less invasive, patients can recover quicker and return to their daily activities sooner.
5. **Improved Quality of Life**: Laparoscopic surgery can improve the quality of life for patients by alleviating symptoms and resolving underlying medical issues.
In summary, laparoscopic surgery is a minimally invasive surgical technique that offers numerous benefits, including reduced pain, faster recovery, lower risk of infection, and improved visualization, making it a preferred approach for various surgical procedures in the abdominal and pelvic regions.
