Laparoscopic Appendectomy

Intro & Advantages - Scope It Out!

• Laparoscopic Appendectomy (LA):

  • Minimally invasive surgical removal of the vermiform appendix.
  • Procedure: Uses 3-4 small ports (5-10mm), laparoscope (camera), specialized instruments.
  • Often preferred for acute appendicitis, especially in young females & obese patients.

• Advantages: LA vs. Open Appendectomy (OA)

  Feature	Laparoscopic (LA)	Open (OA)
  Post-op Pain	↓ Significantly Less	↑ More
  Hospital Stay	↓ Shorter (e.g., 1-2 days)	↑ Longer (3-5 days)
  Recovery Time	↓ Faster return to activity	↑ Slower
  Cosmetic Outcome	↑ Better (minimal scarring)	↓ Poorer (larger scar)
  Wound Infection Risk	↓ Reduced	↑ Higher
  Diagnostic Ability	↑ Superior (full view)	Limited exploration

⭐ LA is considered the gold standard for uncomplicated acute appendicitis in adults, offering significant benefits over open surgery.

Pre-op & Scoring - Ready for Action!

• Pre-op: H&P, labs (CBC, LFT, RFT), USG/CT. NPO. Prophylactic IV antibiotics (e.g., Cefazolin + Metronidazole) 30-60 mins pre-incision. Informed consent.
• Scoring Systems:
  • Alvarado (📌 MANTRELS): Score >7 indicates high probability.
  • AIR Score: Score 9-12 suggests high risk.
• Positioning: Supine, left arm tucked.

⭐ Diagnostic laparoscopy is particularly valuable in young females of reproductive age presenting with right iliac fossa pain to differentiate from gynecological pathologies.

Technique & Ports - The Main Snip!

• Pneumoperitoneum:
  • CO₂ insufflation to 12-15 mmHg.
  • Access: Umbilical (Veress needle or Hasson open technique).
• Port Placement: (📌 "Baseball Diamond")
  • Optical (10/12mm): Umbilical (camera).
  • Working (5mm) x2: LLQ (main dissection), Suprapubic (retraction).
  • 
• Key Surgical Steps:

⭐ The critical view of safety for appendectomy involves clear circumferential dissection and identification of the appendiceal base at its junction with the cecum before division.

Complications & CIs - Watch These Spots!

• Complications:
  • Intra-op: Bleeding, bowel injury.
  • Early Post-op: Port infection, intra-abdominal abscess (IAA).
  • Late: Port-site hernia, stump appendicitis.
• Contraindications (CIs):
  • Absolute: Hemodynamic instability.
  • Relative: Severe peritonitis, advanced pregnancy, extensive adhesions, coagulopathy.

⭐ Stump appendicitis, though rare, is an important delayed complication if the appendiceal stump is left too long (typically >0.5 cm).

High‑Yield Points - ⚡ Biggest Takeaways

• Laparoscopic appendectomy is the gold standard for most acute appendicitis cases.
• Key benefits: ↓ pain, ↓ hospital stay, ↓ wound infections, better cosmesis.
• Pneumoperitoneum (CO2: 10-15 mmHg) via Veress needle or Hasson technique.
• Common 3-port placement: umbilical (camera), suprapubic, and Left Lower Quadrant.
• Mesoappendix and appendiceal base managed with staplers, clips, or endoloops.
• Risk of intra-abdominal abscess may be ↑, especially in perforated appendicitis.
• Convert to open for dense adhesions, uncontrolled bleeding, or difficult anatomy.
