Colonoscopy — Indications and Contraindications
This chapter discusses some of the major indications and contraindications for colonoscopy. Advances in colonoscopic techniques have expanded the role of colonoscopy beyond conventional screening, surveillance, and diagnosis to various complex therapeutic and interventional utilities. Several guidelines with new information are being published and updated regularly in the field of colonoscopy and are currently used in clinical practice. However, there is still a lack of well-designed randomized clinical trials investigating the role of colonoscopy in early diagnosis and treatment of various conditions and its impact on long-term survival and disease status. Nevertheless, retrospective observational studies and a few randomized clinical trials abundantly supply data supporting the role of colonoscopy in the diagnosis and management of colonic pathologies in the absence of comparable alternatives.

Screening and Surveillance Colonoscopy
Colorectal cancer is a major cause of worldwide morbidity and mortality. As such, there are many guidelines and recommendations set forth by various medical societies regarding colonoscopy for screening and surveillance. The universal goal of these guidelines is to reduce colorectal cancer prevalence and mortality. Recommendations for colorectal cancer screening and surveillance using colonoscopy vary slightly between medical society guidelines and are often dictated by some combination of age, known disease severity, length of time since last study, family history, and comorbid conditions.
