A four-component study was designated to evaluate the possible risk of perforation during barium enema examination following biopsy of the rectum or colon. The study included a survey of gastrointestinal radiologists, an in vitro study of pig colons after biopsy, colon pressure measurements in human subjects, and histological analysis of human colonoscopic biopsy specimens. The results suggest that superficial biopsy of the rectum of colon performed with small colonoscopic forceps is a safe procedure and no waiting period is necessary before performing a barium enema study. However, biopsy of the colon or rectum with proctoscopic forceps appears to have greater potential for perforation and a waiting period between biopsy and barium enema study is recommended. Radiologists should distinguish between proctoscopic and colonoscopic biopsy procedures before determining when a barium enema study will be performed following biopsy.
一项四项内容的研究旨在评估直肠或结肠活检后钡剂灌肠检查期间穿孔的可能风险。该研究包括对胃肠放射科医生的调查、活检后猪结肠的体外研究、人体结肠压力测量以及人体结肠镜活检标本的组织学分析。结果表明，使用小型结肠镜钳对结肠直肠进行浅表活检是一种安全的操作，在进行钡剂灌肠检查之前无需等待期。然而，使用直肠镜钳对结肠或直肠进行活检似乎有更大的穿孔可能性，建议在活检和钡剂灌肠检查之间设置等待期。放射科医生在确定活检后何时进行钡剂灌肠检查之前，应区分直肠镜和结肠镜活检程序。
