Overview
Rectal polyps are abnormal growths projecting from the surface of the rectal mucosa. They can vary in histology, including villous adenomas, and may present with symptoms mimicking infectious gastroenteritis 2.Diagnosis
Endoscopic visualization is essential for diagnosis 12.
Biopsy confirmation is required for histological grading (adenoma, villous, tubulovillous) 2.
Imaging (e.g., CT, MRI) may be needed for staging or assessing complications 1.Management
Endoscopic Polypectomy: Transanal use of devices like MULTIFIRE ENDO GIA for hemostatic excision of broad-based polyps 1.
Surgical Resection: Considered for large, high-grade lesions or those with high risk of malignancy 1.
Follow-Up: Regular surveillance endoscopy recommended for patients with polyps to monitor recurrence 1.Special Populations
Elderly: Villous papillomas can present atypically, mimicking infectious conditions 2.
Comorbidities: Management may need adjustment based on patient comorbidities, though specific details are not provided 12.Key Recommendations
Utilize transanal endoscopic techniques such as MULTIFIRE ENDO GIA for the resection of broad-based rectal polyps to ensure hemostasis 1 (Evidence: Moderate).
Conduct endoscopic biopsy for definitive histological classification of rectal polyps 2 (Evidence: Weak).
Implement regular follow-up endoscopy for patients post-polypectomy to monitor for recurrence 1 (Evidence: Expert opinion).References
