Colonoscopy is widely regarded as one of the most safe and effective screening procedures for detecting colorectal cancer. While complications can occur, the vast majority of injuries associated with colonoscopies are preventable through proper technique, adequate training, and adherence to long-established and published safety protocols. Understanding the nature of these potential injuries, how to prevent such injuries, and the prompt recognition and treatment of such injuries, is crucial for gastroenterologists and surgeons to know. Poulos & Coates has represented dozens of clients who have sustained perforation injuries at colonoscopy.
The most serious complication from colonoscopy is perforation of the colon wall. Perforations occur in approximately 1 in 1,000 to 1 in 1,500 procedures. Most perforations are avoidable and result from mechanical pressure during instrument insertion, excessive CO2 insufflation (also known as barotrauma), or manipulation in tenuous areas of the colon with existing disease or scarring. Experienced endoscopists who use gentle technique, and who carefully navigate through difficult anatomical areas can significantly reduce this risk. Additionally, proper patient selection and pre-procedure evaluation can identify individuals at higher risk, allowing for modified approaches or alternative screening methods not involving endoscopy. The elderly are particularly prone to perforation at colonoscopy, given their relatively thinner colonic walls.
Bleeding is another colonoscopy complication that can occur, particularly when polyps are removed. While some bleeding is expected with polypectomy, significant hemorrhage is largely preventable through careful assessment of polyp characteristics, appropriate use of electrocautery settings, and proper management of patients on blood-thinning medications. Following national guidelines for when to hold or continue anticoagulant therapy, using techniques like cold snare polypectomy for smaller lesions, and applying hemostatic clips when needed can minimize most bleeding complications.
The safety record of colonoscopy demonstrates that with proper training, technique, and adherence to quality standards, the colonoscopy carries minimal risk. Ongoing education for endoscopists and implementation of quality improvement programs can further reduce complication rates. While no medical procedure is entirely without risk, medical evidence clearly shows that the overwhelming majority of colonoscopy-related injuries are preventable, making it a remarkably safe tool for colorectal cancer screening and diagnosis when performed by skilled practitioners following best practices.
