Difficult Appendesectomy In Surgical Practice
Introduction 1889 Mac Burney described location, the clinical features of appendicitis and the importance of operative intervention and muscle-splitting incision.
Surgical Anatomy Surface anatomy Development: diverticulum of ceacum appearing in the 8th week of life Positions: constant base, tip varies (retroceacal, pelvic, subcaecal, preileal, pericolic)
ACUTE APPENDICITIS Incidence 0.1-0.2% Appendectomy for appendicitis is the most common performed emergency operation in the world. Disease of young with 40 % of cases being between 10-24 Yr
EITIOLOGY AND PATHOGENESIS Obstruction of the lumen is the dominant causal factor. The obstructing object can be: *fecalith ; the most common *lymphoid tissue hypertrophy *inspisated barium from previous study *tumors *seeds
Fecalith
BACTERIOLOGY Bacteria cultured in cases of appendicitis are similar to those seen in other colonic infection. The principal organisms seen are E. coli and Bacteroid fragilis.
Histology Histological terms used: Catarrhal appendicitis Inflamed Suppurative Necrotic Gangrenous Perforated Appendicular mass
ALVARADO SCALE 9-10: almost certain appendicitis and should go to OR. 7-8: high likelihood of appendicitis, imaging study. 5-6: compatible but not diagnostic, CT scan is appropriate. 0-4: extremely unlikely.
Treatment Adequate hydration, correct electrolyte imbalance Manage other medical problems Pre-operative antibiotics: Simple AP - hrs antibiotic Ruptured AP - antibiotic until fever Peritonitis - 10 days antibiotics
Surgery: Open appendectomy Laparoscopy NOTES McBurney (oblique); Rocky Davis (transverse); right paramedian; midline incision Laparoscopy NOTES

patient. General condition Obesity The Very Young The Very Old In AIDS Patients The Pregnant woman
Obesity with acute appendicitis
The Very Young Diagnosis may be more difficult to establish Children are more likely to progress to perforated appendix (? Under-developed Greater Omentum).
Children with acute appendicitis
The Very Old Greater morbidity and mortality Less typical presentation Cancer may be a possibility as an underlying cause. Perforation of 50% and mortality of 20% has been reported
old with acute appendicitis
In AIDS Patients Be aware of CMV or Kaposi sarcoma as the underlying cause General condition Risk of infection
The Pregnant More common in the first two trimesters The appendix is pushed superiorly and laterally Premature Labor 10-15% with surgery Perforated appendix leads to fetal death in 20%
Pregnant woman with acute appendicitis
Position of Appendix
Surgical Approach Incision over point of maximal tenderness Midline incision if diffuse peritonitis, or doubt about diagnosis Tilt table 30° to left Minimize uterine manipulation to decrease risk of irritability and preterm labor External fetal monitoring – especially if perforation
