Definition

The term "appendiceal abscess" consists of the two words abscess and appendix. An abscess is a severe accumulation of fluid that develops as a result of a bacterial infection. In the lower right quadrant of the digestive tract, the appendix is a finger-shaped section of the intestine that connects to the intestine via a small canal. An appendiceal abscess is the result of inflammation in the appendix, leading to the formation of a bag filled with pus that is at risk of rupture. Phlegmon is another term for an appendix abscess.

Pain may be experienced as a result of the body's efforts to fight the infection that is present in the abscess bag. It is a complication of appendicitis. An appendiceal abscess is a rare condition that necessitates medical attention to drain the pus. Before undergoing surgery, antibiotics may be administered as an additional treatment option to reduce inflammation and eradicate infection in order to treat an appendiceal abscess. Always seek medical professional recommendations in order to decide the most appropriate treatment. It is essential to raise awareness regarding the complications associated with an inflamed appendix.

Causes

The formation of an abscess around the appendix is a result of appendicitis, which is inflammation of the appendix. The appendix is anatomically distinct, with a narrow canal measuring about 8 to 10 centimeters in diameter. Inflammation and bacterial growth in the appendix occur when foreign bodies, such as food, get stuck in the large intestine and restrict its passage. An inflamed appendix might rupture, allowing infection to spread across the abdominal cavity. Nevertheless, once the wall of the appendix ruptures and results in an accumulation of pus, an appendiceal abscess is inevitable. This particular complication is observed in 2–6% of appendicitis cases. 

Risk factor

Although appendiceal abscess may affect anyone, the following are some of the risk factors that can be associated with it:

1. Age: Appendicitis frequently affects young adults in their 20s.
2. Gender: Appendicitis is more prevalent among males.
3. Family history of appendicitis
4. Children with a prior history of cystic fibrosis

Symptoms

Appendicitis symptoms appear prior to the onset of an appendiceal abscess. Typically, the pain originates in the central region of the abdomen and gradually progresses towards the lower right side. The pain typically develops in intermittent episodes. Once the pain has shifted to the lower right region, it will persist and typically be intense. Coughing or walking are also activities that may potentially trigger muscle contraction in the lower abdomen, which may also make the pain worse. Additional signs and symptoms of appendicitis include the following:

1. Nausea
2. Loss of appetite and fatigue
3. Constipation or diarrhoea
4. A fever, followed by a flushed face and a sensation of warmth.
5. Flatulence and farting difficulty

Diagnosis

Following a physical examination of the abdomen, the doctor will inquire about the patient's symptomatic history through an interview. Examinations performed to diagnose appendiceal abscess consist of:

1. Physical examination: As part of the physical examination, the abdominal condition is evaluated. The doctor may apply gentle pressure to the stomach and release it quickly. Pain worsens with appendicitis.

2. Laboratory examination: A blood test is performed to identify the white blood cell count; increased levels may indicate infection.

3. Urinalysis: to exclude the potential of pain from a urinary tract infection

4. Radiological examination: X-ray, CT scan, or MRI to confirm appendicitis or other gastrointestinal diseases.

Management

Do not self-medicate with pain relievers if you or a loved one are experiencing severe abdominal pain; instead, seek medical attention immediately. 

The use of analgesics to treat pain might obscure symptoms and inhibit medical professionals' ability to perform examinations.

Abscess treatment for appendicitis remains controversial. There are two treatment modalities available for appendix abscesses: non-invasive and invasive.

• Non-invasive treatment

The doctor will prescribe antibiotics as a non-invasive treatment to reduce the inflammation. This treatment is recommended for appendicitis-suspected children. The elimination of inflammation is performed to prevent the need for additional surgery and potential postoperative complications. This treatment is effective in eighty to one hundred percent of appendiceal abscess cases. Antibiotic treatment is administered for weeks prior to surgery.

• Invasive treatment

Surgical intervention of the infected area is an option for invasive treatment when antibiotics are ineffective at relieving the patient's symptoms. Monitoring symptoms both during and after the medication may determine the response to treatment. If there are no signs of improvement, malignancy should be considered. A colonoscopy may be performed as a diagnostic procedure to identify the presence of cancer.

Preoperative intervention may be necessary in certain conditions to evacuate the purulent fluid. Typically, an interventional radiology specialist performs this surgery. The objective is to decrease inflammation and support the procedure. Appendectomy, also known as the surgical elimination of the appendix, may be performed via laparotomy or laparoscopy.

1. Laparotomy

Laparotomy is a surgical intervention that involves an extensive incision in the abdomen. A large incision provides the surgeon with a wide operating area.

2. Laparoscopy

Laparoscopy is a minimally invasive surgical treatment that utilizes specialised equipment, allowing the doctor to achieve a smaller incision. This may improve the aesthetic outcomes of the operation and accelerate the healing process.

If you have any kind of medication allergy, particularly to antibiotics, it is essential to inform your doctor immediately.

Complications

If there is an abscess that is not treated, it can cause the infection to worsen. This condition can cause the morning to break, and the part of the infection spreads to the stomach wall. This infected part of the stomach wall is called peritonitis. In peritonitis, in addition to the stomach wall, other internal organs are also at risk of being damaged due to the pusket. Peritonitis is an emergency case, which if not treated can be life-threatening. 

Prevention

While it is not possible to prevent all cases of appendicitis, the occurrence of complications such as appendix abscesses can be prevented by promptly seeking appropriate treatment upon the onset of early signs of appendicitis. Prompt intervention is essential to preventing complications.

When to see a doctor?

Persistent, severe abdominal pain is a medical emergency, particularly in females. If you experience prolonged abdominal pain, it is essential to immediately seek medical attention at the nearest healthcare institution for immediate first aid. The following are some more complaints that require particular attention:

1. Acute abdominal pain
2. Hematemesis
3. A mass or lump is present, which has a consistency that is more dense than other gastrointestinal regions.
4. Harsher sensation in a particular part of the abdomen.
5. Fever accompanied by abdominal pain
