| Popis: | Colonoscopy with polypectomy is frequently performed in pediatric patients based on symptoms, with the majority of polyps identified being benign juvenile pedunculated polyps with a vascular stalk. This is in distinction to adults where polypectomy is often performed as part of a colon cancer screening and prevention strategy and a higher fraction of polyps are sessile and or dysplastic. In adults, polypectomy techniques emphasize a need for deeper resection to ensure complete resection of adenomas or potential carcinoma in situ. Adenomatous polyps can occur in the pediatric age group and may be associated with an underlying polyposis, hereditary or chronic inflammatory conditions. Polypectomy techniques include use of cold biopsy forceps for very small polyps, cold snare polypectomy for small sessile polyps and hot snare polypectomy for the majority of polyps in the pediatric age group. Adjuvant techniques include epinephrine volume reduction, saline-assisted polypectomy and hemostatic techniques including injection, clip application and loop application to prevent or treat post-polypectomy bleeding. Electrosurgical principles guide the settings and type of current utilized during hot snare polypectomy. Polypectomy utilizing thermal techniques is associated with a higher risk of complications compared with diagnostic colonoscopy. |
