Introduction:
Gangrenous appendicitis is a serious complication in which the appendix becomes inflamed. The inflammation in gangrenous appendicitis is so severe that the blood supply to the appendix is cut off, causing the tissue to die and become necrotic (gangrenous). Due to a lack of blood flow to the appendix, the tissue becomes infected and eventually dies, resulting in gangrene. Gangrenous appendicitis is a medical emergency requiring immediate treatment, surgery to remove the infected appendix, and antibiotics to prevent infection and promote healing.
What Is Appendicitis?
Appendicitis is an inflammation of the vermiform appendix, a hollow organ located in the lower part of the abdomen near the cecum. Appendicitis has no known cause, but it is thought to be caused by an obstruction in the appendiceal lumen (inner lining of the appendix). This obstruction causes bacterial overgrowth in the appendix, resulting in acute inflammation with abscess formation and perforation, leading to tissue necrosis or gangrene.
What Causes Gangrenous Appendicitis?
The exact cause is unknown, but any obstruction in the appendiceal orifice resulting in inflammation, localized ischemia, lymphoid hyperplasia, perforation, and abscess development can lead to appendicitis. In addition, the appendix begins to fill with mucus and becomes distended due to vascular and lymphatic compromise, making the wall necrotic and ischemic (tissue death due to reduced blood supply), forming gangrenous appendicitis. E.coli, Peptostreptococcus, Bacteroides, and Pseudomonas are the bacteria involved. Once necrosis occurs, the risk of perforation develops, leading to peritonitis and a localized abscess.
What Are the Symptoms of Gangrenous Appendicitis?
The symptoms of gangrenous appendicitis include:
-
Generalized abdominal pain that localizes to the right lower quadrant.
-
Anorexia.
-
Nausea or vomiting.
-
Fever.
-
Diarrhea.
-
Generalized malaise.
-
Urinary urgency.
-
Abdominal pain while walking or coughing.
-
Abdominal rigidity.
-
Blood in the stool.
How Is Gangrenous Appendicitis Diagnosed?
The diagnosis of appendicitis involves:
1. Physical Examination - During a physical examination, the doctor will look for signs of inflammation in the abdomen, such as tenderness or pain in the lower right side. They may also check for a fever, a sign of infection.
2. Laboratory Tests - Lab tests used to diagnose gangrenous appendicitis include:
- Complete Blood Count (CBC) - This test involves the measurement of leucocyte count, neutrophil percentage, and C-reactive protein (CRP). The test shows elevated white blood cell (WBC) levels and CRP. These are all indicators of infection in the body.
-
Blood Culture - This test assesses the blood for bacteria, which can indicate a serious infection.
-
Urinalysis - This test checks the urine for signs of infection or inflammation and shows ketone presence.
-
Imaging Tests - Tests, such as CT (computed tomography) scans or ultrasounds, helps to confirm the diagnosis of gangrenous appendicitis. These tests show the inflamed appendix with 95 % accuracy, which shows an enlarged appendix, appendiceal wall thickening, peritoneal fat stranding. In addition, MRI (magnetic resonance imaging tests) are helpful in pregnant women suspected of appendicitis.
What Are the Treatment and Management Methods for Gangrenous Appendicitis?
The method of treatment for gangrenous appendicitis is listed below:
-
The most common treatment for gangrenous appendicitis is an appendectomy, which involves surgical removal of the infected appendix.
-
In some cases, the surgery is performed through a small incision in the abdomen rather than a larger one (laparoscopic appendectomy).
-
Laparoscopic appendectomy is a minimally invasive procedure that uses small incisions in the abdomen and a camera to guide the surgery. It is associated with less pain and a faster recovery than traditional open surgery.
-
Surgery is needed to clean out the infected tissue if the infection has spread to other parts of the abdomen. This is known as abscess drainage or peritoneal lavage.
-
Antibiotics will be given to prevent infection and promote healing after surgery, and are usually given intravenously (through a vein) and may be continued for several days or weeks, depending on the severity of the infection.
-
Following the surgery, the patients will be closely monitored for any signs of complications such as fever, infection, or bleeding. They will also be given pain medication and encouraged to move as soon as possible in order to prevent blood clots and promote healing. The patient is discharged after a few days or may have to stay in the hospital for longer, depending on the condition and severity.
-
Surgical treatment is the most effective way to treat gangrenous appendicitis, and any delay in surgery leads to more severe complications.
-
Recovery from gangrenous appendicitis may take several weeks or months, and patients experience discomfort or pain while healing. Therefore, regular follow-up visits with the surgeon are essential to ensure that the patient is healing correctly and address any concerns or issues that may arise.
What Are the Potential Complications of Gangrenous Appendicitis?
The potential complications of gangrenous appendicitis are listed below:
-
Peritonitis - Peritonitis an infection of the abdomen lining that can be life-threatening if not treated promptly.
-
Septicemia - Septicemia is a severe infection that occurs when bacteria enter the bloodstream.
-
Abscess - This is a pocket of infected fluid that develops in the abdomen after surgery.
-
Adhesions - Scar tissue can form in the abdomen after surgery, which can cause abdominal pain and bowel obstruction.
-
Wound infection - Any infection at the surgical incision site results in wound infection after the surgery.
-
Anemia - Anemia is a condition with a lack of red blood cells in the body, which causes fatigue and weakness. It occurs due to excessive blood loss during or after surgery.
-
Thrombophlebitis - This involves the formation of blood clots in the vein that can be life-threatening when entered into the lungs.
-
Others - Respiratory complications can happen when the patient has difficulty breathing after surgery.
It is important to note that these complications can be avoided if gangrenous appendicitis is treated promptly and proper aftercare is taken. Furthermore, it is critical to recognize and report any signs and symptoms of these complications, such as fever, abdominal pain, or difficulty breathing, to a doctor as soon as possible.
What Is the Prognosis for Gangrenous Appendicitis?
If gangrenous appendicitis is diagnosed and treated promptly, the prognosis is generally favorable. Most people recover completely from surgery, though they may experience discomfort or pain while recovering. However, if the infection is not treated quickly, complications increase. Sometimes, it leads to serious health problems and can be life-threatening. As a result, it is critical to seek medical attention as soon as symptoms of appendicitis are noticed.
Conclusion:
Gangrenous appendicitis is caused by perforation and necrosis formation as a result of appendicitis's lack of blood supply. The causes are unknown, but it is thought to be due to an obstruction of the appendiceal orifice. The symptoms and diagnosis can aid in the early diagnosis of appendicitis and treatment to avoid complications.
