Summary
Appendiceal tumours are rare, with carcinoid tumours being the most common. While appendectomy suffices for most carcinoid tumours, right hemicolectomy is recommended for cystadenomas or appendiceal cancer.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Appendiceal tumours are uncommon and frequently diagnosed during emergency surgery.
- Their presentation can be challenging, complicating timely decision-making.
Purpose of the Study:
- To analyze the spectrum of appendiceal tumours.
- To discuss their clinicopathological characteristics, diagnostic methods, surgical management, and patient outcomes.
- To review existing literature on appendiceal neoplasms.
Main Methods:
- Retrospective analysis of 1646 appendectomies performed over 10 years.
- Inclusion of 12 patients diagnosed with appendiceal tumours.
- Review of clinical data, histopathology, surgical procedures, and outcomes.
Main Results:
- Twelve appendiceal tumours identified (0.72%): 8 carcinoid, 2 mucinous (mucocele), and 2 adenocarcinoma.
- Carcinoid tumours typically presented as acute appendicitis, diagnosed post-appendectomy.
- Surgical approach varied: appendectomy for most carcinoids, hemicolectomy for cystadenoma near the base or adenocarcinoma.
Conclusions:
- Carcinoid tumours are the most frequent appendiceal neoplasms, often mimicking acute appendicitis.
- Appendectomy is sufficient for localized carcinoid tumours, but right hemicolectomy is indicated for appendiceal cystadenoma or adenocarcinoma.
- Prognosis is favorable for carcinoid and cystadenoma, but poor for disseminated appendiceal adenocarcinoma.
