INTRODUCTION
The appendix is :
-Wormlike extension of the cecum (vermiform
appendix).
-Length is 8-10 cm (ranging from 2-20 cm).
-Fifth month of gestation
-Several lymphoid follicles.
Etiology:
Obstruction of the lumen appendix followed by
infection
Catarrhal appendicitis.
-lymphoid hyperplasia (60% children)
-Gastro enteritis
-Virus
-Acute respiratory infection
-Mononucleosis
Obstructive appendicitis
-fecalith 35% adults.
-foreign body / parasites (4%)
- tumors (1%)

Sonography
Advantages of sonography
1.Noninvasiveness,
2.Short acquisition time
3.Lack of radiation exposure
4.Potential for diagnosis of
other causes of abdominal
pain
5.Pediatric patients
6.Women of childbearing

INDICATIONS
Consider an appendectomy for patients with a
history of :
Persistent abdominal pain
Fever
Clinical signs of localized or diffuse
peritonitis
Especially if leukocytosis is present.
TREATMENT
Medical therapy
Resuscitated adequately with fluids .
Preoperative prophylactic antibiotics
-Acute Appendicitis single agent secondgeneration cephalosporin.
-Perforated appendix triple antibiotic therapy
Ampicillin , gentamycin ,
metronidazol
Antibiotic prophylaxis should be administered
before every appendectomy.
Antibiotic treatment may be stopped.
-Becomes afebrile
-WBC count normalizes
Meckel's diverticulum
- Acute salpingitis
- Crohn's disease

The pain may actually improve.
Symptoms do not completely resolve.
Still have right lower quadrant pain
Decreased appetite
Change in bowel habits (eg, diarrhea, constipation)
Intermittent low-grade fever.
Treatment of
Appendiceal Mass
Nonoperative management
Becomes walled off by omentum and ajacent viscera.
Initially treated with intravenous broad-spectrum antibiotic
Appendiceal Abscess USG or CT scan
-Percutaneous aspiration
-Drain placement
Intravenous antibiotics are continued until the patient
- afebrile for 24 hours
- return of normal gastrointestinal function
- normal WBC count with a normal differential.
At this time, patients are switched to oral antibiotics for a total
antibiotic course of 10-14 days.
Traditionally, interval appendectomy is performed 6-8
weeks later.
