Abstract

Background and Aim: Colonic perforation is the serious accidental complication. The aim of this study is to analyze the clinical presentation and management of recent iatrogenic perforations during therapeutic colonoscopy.

Methods: Consecutive patients referred to four academic cancer centers in Japan were retrospectively reviewed using each center's endoscopy database of medical records. Data was obtained by means of an extensive data collection sheet. Since we evaluated the data including iatrogenic perforation during newly developed therapeutic procedure such as endoscopic submucosal dissection (ESD) or hemoclips, the collection of patient data was set from the period of the beginning of ESD technique in each hospital in this study.

Results: The overall rate of occurrence of perforation was 0.15% (23/15, 160). Perforation rate for EMR (0.58%) showed a significantly higher rate (P < 0.0001) than that for hot biopsy and polypectomy. The rate for ESD (14%) showed a markedly higher rate (P < 0.0001) than that for other standard procedures. Of those perforations, endoscopic clipping was performed in 56.5% of the patients, and conservative treatment was successful in 100% of the patients with successful closure. Both CT scan findings and seology results (WBC, CRP) after perforation were poor predictors for need for surgery as opposed to conservative management.

Conclusions: Further improvements in EMR with special knife techniques are required to simply and safely remove large colorectal neoplasms, because perforation rate for ESD shows a markedly higher. Conservative management may be possible in patients who have undergone complete endoscopic clipping.
