The accuracy of ileo-anal pouch biopsy reporting was assessed.
The pathology reports of 100 consecutive pouch biopsies were reviewed to assess the accuracy and consistency with which the St Mark's histological scoring criteria were applied. The quality of pouch biopsy sampling and provision of clinical and endoscopic information on pathology request forms was also assessed.
In 27% of cases no relevant endoscopic or clinical information was provided with the pathology request form. Separately labelled biopsies from the prepouch ileum, pouch and columnar cuff were submitted in only 4% of cases. In 32% of pathology reports, no acute or chronic St Mark's score was included. In 2% of cases the St Mark's scoring criteria were applied inappropriately. Twenty per cent of cases histologically diagnosed as pouchitis did not include a numerical score. In 30% of cases diagnosed histologically as pouchitis, an acute inflammatory score of < 4 (i.e. insufficient for this diagnosis) was included in the report.
Pouchitis is a combined clinical, endoscopic and histological diagnosis. The correct interpretation and application of the St Mark's histological scoring criteria for pouch biopsies is an important part of this diagnostic process.
评估回肠肛管吻合术活检报告的准确性。
回顾了 100 例连续的吻合术活检报告，以评估 St Mark 组织学评分标准的应用准确性和一致性。还评估了吻合术活检取样的质量以及在病理申请单上提供临床和内镜信息的情况。
在 27%的病例中，病理申请单未提供相关的内镜或临床信息。仅有 4%的病例分别提供了吻合前回肠、吻合术和柱状袖口的单独标记活检。在 32%的病理报告中，未包括急性或慢性 St Mark 评分。在 2%的病例中，不恰当地应用了 St Mark 评分标准。20%的组织学诊断为吻合术炎的病例未包括数值评分。在 30%的组织学诊断为吻合术炎的病例中，报告中包括了<4 的急性炎症评分（即不足以诊断为此病）。
吻合术炎是一种综合的临床、内镜和组织学诊断。正确解释和应用 St Mark 组织学评分标准是这一诊断过程的重要组成部分。
