Accuracy of pathologic interpretation of colorectal polyps by general pathologists in community practice

摘要: Abstract Background: The histologic features of colorectal polyps often guide colonoscopic surveillance and the need for surgical intervention. Our objective was to evaluate pathologic interpretation by general pathologists in community practice. Methods: Twenty slides were reviewed 20 randomly selected There 5 malignant polyps, 9 adenomas, 6 miscellaneous polyps. Results: Cancer correctly identified 91% readings adenoma 94%. grade differentiation cancer provided 55% readings, comment regarding whether resection margin free made 50% pathologists. Tubular called tubulovillous or villous 35% but seldom (2%) tubular. High-grade dysplasia 47% 60 invasive 22%, missed 31%. Among hyperplastic polyp recognized 75% cases, inflammatory juvenile each 16 (80%). Peutz-Jeghers hamartoma 4 (20%), polypoid phase solitary rectal ulcer syndrome 2 (10%). Conclusion: Areas strength with regard colon practice included identification cancer, adenoma, certain non-neoplastic (e.g., polyps). weakness lack on proximity line, erroneous high-grade dysplasia, rare lesions. results this study suggest areas which focus continuing education continuous quality improvement efforts interpretation. (Gastrointest Endosc 1999;50:468-74.)
