Study Notes
Appendix Location Options
- Commonly located inside the peritoneum with the tip directed downwards.
- Position variations include pelvic, right iliac fossa, medial, retrocecal, under ileum, and lateral.
- Subhepatic location occurs, particularly in pregnant women during the third trimester.
Clinical Symptoms of Appendicitis
- Characteristic pain in the right lower quadrant, known as McBurney's Point.
- Accompanied by nausea and vomiting.
- Severe abdominal pain, fever, reduced appetite, and potential bowel changes (constipation or diarrhea).
- Rebound tenderness may indicate inflammation.
Appendicitis Overview
- Inflammation of the appendix, primarily caused by obstruction of the appendiceal lumen.
- Common obstructive factors: lymphoid hyperplasia, fecaliths, foreign bodies, tumors, or parasites.
- Leads to distension, bacterial overgrowth, ischemia, and inflammation.
- Untreated cases risk necrosis, gangrene, and perforation, potentially forming an abscess.
Appendicitis Classification (V.I. Kolesov, 1972)
- Acute appendicitis can be classified into mild, simple, destructive, or complicated forms:
- Mild (appendicular colic)
- Simple (surface)
- Destructive:
- Phlegmonous
- Gangrenous
- Perforated
- Complicated:
- Appendicular infiltrate
- Appendicular abscess
- Suppurative peritonitis
- Other complications (e.g., sepsis, pylephlebitis)
Appendix Anatomy
- Serves as a continuation of the cecum, located at the convergence of three longitudinal bands.
- Average length is 7-10 cm, often containing a mesentery that includes nerves and the appendicular artery.
Complications of Acute Appendicitis
- Appendicular infiltration can evolve to abscess formation within several weeks.
- Risk of common purulent peritonitis and intra-abdominal abscesses (e.g., pelvic, subphrenic).
- Possible progression to severe conditions such as pylephlebitis, liver abscess, and sepsis.
Diagnosis of Appendicitis
- Involves thorough patient history and symptom identification through physical examination.
- Laboratory tests reveal leukocytosis and neutrophilia.
- Urine tests may assess neutrophil-leukocyte ratios.
- Imaging methods used include abdominal radiography, ultrasound, CT scans, and laparoscopy.
Historical Context of Appendectomy
- McBurney described the point of tenderness and surgical method in 1889.
- Kurt Semm performed the first laparoscopic appendectomy in 1983.
- Claudius Aymand conducted the first successful appendectomy in 1735.
- Reginald Fitz coined the term "appendicitis" in 1886.
Appendectomy Overview
- Procedure for removing the appendix, which can be open (laparotomy) or laparoscopic.
- Indications include acute and subacute appendicitis or diagnostic laparoscopy.
- Contraindications include coagulopathy, cardio-respiratory instability, or extensive prior adhesions.
Types of Appendectomy
- Open appendectomy involves a larger incision versus the minimally invasive laparoscopic method.
- Retrograde appendectomy is utilized for retrocecal appendices, removing it base-first during laparotomy.
- Antegrade appendectomy, common in laparoscopic surgeries, begins at the appendix end.
Laparoscopic vs. Open Appendectomy
- Laparoscopic approach requires three small incisions with the use of specialized tools.
- Open appendectomy is performed via a single larger incision in the lower right abdomen, potentially causing a longer recovery time.
