What is an appendiceal polyp?

Polyps at the appendiceal orifice (AO) are rare and can pose unfamiliar endoscopic territory to colonoscopists. AO polyps pose a risk for appendiceal obstruction and resulting appendicitis in addition to malignant potential.

How would you address a polyp involving the appendiceal orifice?

Polyps that involve the appendiceal orifice are currently unable to be fully removed safely colonoscopically as the appendix is unable to be removed with the specimen. Laparoscopic “radical appendectomy” or partial cecectomy has been shown to be a safe method for removing polyps that involve the base of the appendix.

Can you see appendix during colonoscopy?

In conclusion, colonoscopy can be useful in the diag- nosis of appendicitis when the clinical presentation is atypical and/or imaging studies are nondiagnostic.

What causes obstruction of the appendiceal lumen?

Luminal obstruction is the pathologic hallmark of acute appendicitis. The most common cause of luminal obstruction is fecaliths, followed by enlarged lymph nodes and tumours. Tumours of the appendix are very uncommon and account for approximately 1% of appendectomies [3].

What is Tubulovillous adenoma?

A tubulovillous adenoma is a non-cancerous growth in the colon. It develops from the glands in the mucosa on the inside surface of the colon. These adenomas can develop anywhere along the length of the colon from the cecum to the rectum.

Why have a colonoscopy after appendectomy?

Background: Mechanical obstruction of the appendiceal lumen is proposed as a possible factor in the pathogenesis of acute appendicitis. Hence, patients over the age of 40 are often referred to a follow-up colonoscopy after admission for acute appendicitis.

Is your appendix attached to your colon?

The appendix is a small, tube-like structure attached to the first part of the large intestine, also called the colon. The appendix is located in the lower right portion of the abdomen, near where the small intestine attaches to the large intestine.

Why does appendicitis lead to death?

Pressure and infection cause inflammation and severe localized pain and tenderness. The wall of the appendix can then break open, spilling the toxic contents into the abdominal cavity, causing diffuse pain and infection. This is called peritonitis, and it can be fatal.

What complications may occur as a result of appendicitis?

Complications of appendicitis may include wound infection, dehiscence, bowel obstruction, abdominal/pelvic abscess, and, rarely, death. Stump appendicitis also occurs rarely; however, at least 36 reported cases of appendicitis in the surgical stump after previous appendectomy exist.
