Summary
Appendiceal carcinoid tumors are rare, often presenting as appendicitis. Simple appendectomy is effective for tumors under 1 cm, with no adjuvant therapy needed.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Appendiceal carcinoid tumors are rare neuroendocrine neoplasms.
- Diagnosis is often incidental during appendectomy for suspected appendicitis.
Purpose of the Study:
- To present the management experience of appendiceal carcinoid tumors at a single center.
- To analyze the clinical presentation, histopathology, and outcomes.
Main Methods:
- Retrospective review of 1237 appendectomies (2000-2004).
- Analysis of patient demographics, clinical data, surgical reports, and follow-up outcomes.
Main Results:
- Five appendiceal carcinoid tumors (0.4%) were identified.
- All presented with acute appendicitis; mean tumor diameter was 0.6 cm.
- All patients remained disease-free after appendectomy with a mean follow-up of 33 months.
Conclusions:
- Appendiceal carcinoid tumors frequently mimic acute appendicitis.
- Simple appendectomy is sufficient for tumors ≤1 cm, potentially with mesoappendix resection.
- Early diagnosis and appropriate surgical management lead to favorable outcomes.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:29Appendicitis-II: Diagnostic Studies and Management
Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

01:22Appendicitis-I: Introduction
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
