Pseudomyxoma peritonei: review on a cluster of peritoneal mucinous diseases
1Department of General Surgery, Hospital Centre of Dinant, Belgium.
Abstract:
Pseudomyxoma peritonei is an uncommon condition characterized by abundant extracellular mucinous material and peritoneal tumoural implants. A ruptured appendiceal mucinous adenoma seems to be the most common origin, but low grade ovarian malignancies are often associated. Peritoneal gelatinous diseases must be subdivided into disseminated peritoneal adenomucinosis, peritoneal mucinous carcinomatosis and intermediate cases. These entities have significantly different prognosis. Debulking surgery is the most common treatment but some are in favour of an ultra radical surgery with hyperthermic intra-peritoneal chemotherapy, with some encouraging results.
Insights
Pseudomyxoma peritonei, a rare condition of mucinous material and implants, often originates from appendiceal or ovarian tumors. Subdividing these peritoneal gelatinous diseases is crucial for prognosis and treatment.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Oncology
- Gynecologic Oncology
Background:
- Pseudomyxoma peritonei is a rare condition involving abundant extracellular mucinous material and peritoneal tumor implants.
- It is most commonly associated with ruptured appendiceal mucinous adenoma but can also involve low-grade ovarian malignancies.
- Peritoneal gelatinous diseases require subdivision into disseminated peritoneal adenomucinosis, peritoneal mucinous carcinomatosis, and intermediate forms due to differing prognoses.
Purpose of the Study:
- To review the characteristics of pseudomyxoma peritonei.
- To emphasize the importance of classifying peritoneal gelatinous diseases.
- To discuss current and emerging treatment strategies.
Main Methods:
- Literature review of pseudomyxoma peritonei and related peritoneal gelatinous diseases.
- Analysis of common origins, including appendiceal and ovarian sources.
- Evaluation of surgical and chemotherapeutic treatment modalities.
Main Results:
- Pseudomyxoma peritonei presents with extensive mucinous ascites and peritoneal implants.
- Appendiceal and ovarian malignancies are frequent origins.
- Disseminated peritoneal adenomucinosis, peritoneal mucinous carcinomatosis, and intermediate types show distinct prognoses.
Conclusions:
- Accurate classification of peritoneal gelatinous diseases is essential for patient management.
- Debulking surgery is a standard treatment.
- Ultra-radical surgery combined with hyperthermic intraperitoneal chemotherapy shows promising results for select cases.
