[Surgical techniques of appendectomy for acute appendicitis]

Area of Science:

• General Surgery
• Minimally Invasive Procedures

Context:

• The treatment of acute appendicitis has evolved significantly with the introduction of laparoscopic surgery over the past two decades.
• Despite its widespread adoption, the overall value and optimal application of laparoscopic appendectomy remain subjects of ongoing discussion and research.

Purpose:

• To evaluate the comparative effectiveness, safety, and cost-benefit of laparoscopic appendectomy versus traditional open appendectomy.
• To identify specific patient populations and clinical scenarios where laparoscopic appendectomy offers distinct advantages or poses contraindications.

Summary:

• Laparoscopic appendectomy is linked to reduced complication rates and shorter recovery times compared to open surgery in the general population.
• While initial operative costs are higher, laparoscopic appendectomy demonstrates a lower overall global cost.
• Specific advantages are noted in obese patients and those with complicated appendicitis (gangrenous or ruptured), though it is contraindicated during pregnancy due to increased miscarriage risk.
• Techniques like stump ligation can reduce costs associated with surgical staplers.
• Management of incidental Meckel's diverticulum during appendectomy differs between pediatric (routine removal) and adult (pathology-dependent removal) populations.

Impact:

• Laparoscopic appendectomy represents a significant advancement in acute appendicitis management, offering improved patient outcomes and potential cost savings.
• Further research and refinement of techniques are necessary to address remaining questions and optimize its application across diverse patient groups.
