Gastrointestinal endoscopy is frequently necessary in high-risk patients in critical care units. This review analyzes recent publications dealing with the safety and efficacy of gastrointestinal endoscopy in patients with high-risk conditions, including acute myocardial infarction, pregnancy, AIDS, recent gastrointestinal surgery, and chronic obstructive pulmonary disease. In general, the various endoscopic procedures that might be performed are relatively safe in stable patients in whom endoscopy is contemplated for clinically important indications. Clinically unstable patients are more likely to have complications. The safety of colonoscopy in pregnancy has not been adequately studied. Laparoscopic surgery in pregnancy needs further study, but may be done with proper maternal and fetal monitoring. In situations in which endoscopy cannot be performed, it can usually be deferred until stabilization of the underlying condition.
