Endoscopic management of colonic perforations.

Purpose of review: We will review the current management of colonic perforations, with particular emphasis on iatrogenic perforations caused by colonoscopy, the leading etiology. We will focus on recently developed endoscopic techniques and technologies that obviate morbid emergency surgery (the standard management approach in years past).

Recent findings: Colonic perforations are rare but potentially fatal complications of both diagnostic and therapeutic colonoscopy resulting in death in approximately 5% of cases with the mortality increasing with delay in diagnosis and treatment. As novel endoscopic techniques and tools have flourished in recent years, our approach to management of these perforations has evolved. With the availability of newer tools such as over the scope clips, enhanced through the scope clips and novel endoscopic suturing devices, colonic perforations can be managed effectively in many or most patients without the morbidity of surgical interventions.

Summary: With expanding use of colonoscopy, inadvertent outcomes such as perforations are bound to increase as well. Early diagnosis permits minimally invasive, nonsurgical, endoscopic management in most cases if the expertise and tools are available. Centers with high colonoscopy volumes including therapeutic procedures would be well served to invest in the requisite technologies and expertise.
