What is laparoscopy?

Laparoscopy: A Minimally Invasive Surgical Technique

Laparoscopy is a minimally invasive surgical technique that allows visualization and intervention within the abdominal cavity through small incisions using specialized instruments and cameras, offering reduced morbidity, shorter hospital stays, and faster recovery compared to traditional open surgery. 1

Definition and Basic Technique

• Laparoscopy involves inspecting the abdominal cavity through an endoscope, typically using carbon dioxide to insufflate the abdomen to facilitate visualization 2
• The procedure utilizes small incisions (typically 0.5-1.5 cm) through which a camera and surgical instruments are inserted, allowing surgeons to perform both diagnostic and therapeutic procedures 3
• It requires specialized equipment including a camera system, insufflation device, and specially designed surgical instruments 1

Clinical Applications

• Diagnostic purposes: Evaluating abdominal pain, identifying sources of infection, assessing organ viability, and staging malignancies 1, 4
• Therapeutic interventions: Primary repair of perforations, resection of diseased tissue, drainage of abscesses, and management of various abdominal emergencies 1
• Emergency settings: Management of iatrogenic colonoscopy perforations, incarcerated hernias, appendicitis, and other acute abdominal conditions 1
• Specific applications include:
  • Evaluation of bowel viability in cases of suspected ischemia 1
  • Assessment and repair of iatrogenic colonoscopy perforations 1
  • Management of incarcerated or strangulated hernias 1, 5

Advantages Over Open Surgery

• Significantly lower wound infection rates compared to open procedures 1, 6
• Reduced postoperative pain and analgesic requirements 3, 7
• Shorter hospital stays and faster return to normal activities 1, 3
• Lower rates of postoperative complications including venous thromboembolism 1
• Improved cosmetic outcomes due to smaller incisions 7
• Ability to visualize the entire abdominal cavity through minimal access 1

Specific Benefits in Emergency Settings

• Allows both diagnostic assessment and potential therapeutic intervention through the same approach 1
• Enables visualization of parietal defects, their size, and specific location in cases of perforation 1
• Permits evaluation of peritonitis and facilitates peritoneal washout and drainage when needed 1
• May prevent progression to more invasive measures such as open laparotomy 1
• Particularly beneficial for early diagnosis and timely management of abdominal emergencies 1, 6

Limitations and Contraindications

• May be challenging in patients with hemodynamic instability or severe sepsis 1
• Increased intra-abdominal pressure from pneumoperitoneum can cause acid-base disturbances and cardiovascular/pulmonary changes in critically ill patients 1
• Requires specialized training and equipment, which may not be available in all settings 1
• Higher conversion rates to open surgery in complex emergency cases 6
• May be contraindicated in patients with severe cardiopulmonary disease who cannot tolerate pneumoperitoneum 2

Emerging Trends

• Single port access surgery (SPA) represents a further evolution of minimally invasive techniques, using a single 2 cm incision via the umbilicus 7
• Robotic-assisted laparoscopy provides enhanced visualization and precision, particularly beneficial in complex procedures 3
• Integration with other imaging modalities for improved intraoperative decision-making 1

Conclusion

Laparoscopy has revolutionized abdominal surgery by providing a minimally invasive approach that reduces surgical trauma while maintaining or improving surgical outcomes. Its applications continue to expand across various surgical specialties, offering significant benefits to patients in both elective and emergency settings 1, 3.
