Study Notes

### Acute Appendicitis

The acutely inflamed appendix can rupture within 24 hours.
Rapid diagnosis and treatment are important due to the risk of perforation.
Diagnostic testing and preoperative treatment are limited due to the urgency of the situation and the low incidence of surgical complications.
Patients are admitted to the hospital and given intravenous fluids.
Oral food and fluids are withheld until a diagnosis is confirmed.
Abdominal CT scan is the preferred imaging method to diagnose acute appendicitis and reduce the rate of negative surgeries.
CT scans with or without contrast can be used, with contrast providing additional data in cases of ruptured appendix with localised abscess.
Ultrasound and MRIs are not as accurate as CT scans.
Ultrasound can be used for children who have difficulty lying still during a CT scan and for pregnant women.
MRIs can be used for pregnant patients where abdominal contents should not be pressed on or exposed to radiation.
White blood cell count with differential will likely show an elevated total white blood cell count, with an increased number of immature white blood cells (bands).

Treatment

The treatment of choice for acute appendicitis is appendectomy (surgical removal of the appendix).
Appendectomy can be performed using minimally invasive laparoscopic techniques, open incision, or abdominal laparotomy.
In cases of ruptured appendix and peritonitis, normal saline irrigation and drainage tubes may be used.
Intravenous hydration is crucial for patients undergoing appendectomy.
Some research suggests that uncomplicated appendicitis (unruptured appendix and no evidence of peritonitis) can be treated nonsurgically with antibiotics.
Clinical trials demonstrate quick recovery and no higher incidence of ruptured appendix with antibiotic treatment for uncomplicated appendicitis.
However, diagnosing uncomplicated appendicitis can be challenging, antibiotics may miss malignant causes, and there is no standard protocol for antibiotic usage.
There is also a potential for reoccurrence of appendicitis (up to 38%) with antibiotic treatment.

### Preoperative Analgesics

Analgesics are used preoperatively to relieve pain and facilitate physical examination and diagnosis.
Analgesics are particularly helpful when surgery is delayed due to limited resources.

Preoperative Antibiotics

Antibiotics are administered preoperatively within 60 minutes of the initial incision after appendicitis diagnosis.
Antibiotics used include cephalosporin, carbapenem, combination penicillin, or a combination of a cephalosporin and metronidazole.
Antibiotics are re-administered before surgery if surgery is delayed.
Postoperative antibiotics are typically not given unless a perforation or other complications occur.

Appendicitis in Children and Adolescents

Children under 4 rarely develop appendicitis.
Appendicitis often progresses to rupture in young children due to difficulty in communicating symptoms.
Infants may present with listlessness, inconsolability, vomiting, and a distended abdomen.
Low diagnostic priority for appendicitis in infants can lead to delayed diagnosis and an increased risk of rupture, complications, and death.
Older children may exhibit atypical signs like lethargy, immobility, and guarding.
Cultural factors influence appendicitis diagnosis and treatment in children.
Children of color, specifically Black and Hispanic, are more likely to experience delayed diagnosis and less likely to receive definitive diagnostic imaging.
These disparities contribute to higher perforation rates in Black, Hispanic, and other children of color compared to white children.
Black children are less likely to receive adequate pain medication in emergency departments for appendicitis.

Appendicitis in Pregnant Women

Acute appendicitis is a common surgical condition in pregnant women.
The typical signs of appendicitis may be less prominent in pregnant women, with heartburn, flatus, nausea, vomiting, and right lower abdominal tenderness being more common.
Ultrasound is the initial imaging modality, followed by MRI if inconclusive.
Appendicitis should remain a diagnostic consideration even if the ultrasound does not locate the appendix.
Surgical intervention is the treatment for appendicitis, and outcomes for non-ruptured appendices are similar to those in non-pregnant women.
Rupture of the appendix increases the risk of fetal loss significantly.

Appendicitis in Older Adults

Older adults may have a diminished inflammatory response due to a weakened immune system, leading to atypical presentations of appendicitis.
Nonspecific symptoms like abdominal pain or confusion may be the only signs of infection.
Older adults are less likely to seek care due to ambiguous symptoms, resulting in higher perforation rates.
Laparoscopic appendectomy offers better outcomes for older adults with both uncomplicated and complicated appendicitis, including shorter hospital stays, higher rates of home discharge, and fewer complications.
