Complex gastrointestinal (GI) conditions such as bowel obstructions, enterocutaneous fistulas, and other enteric maladies are major causes of morbidity and mortality; are rising in incidence worldwide; and may benefit from the integration of interventional radiology techniques into current surgical/endoscopic management strategies, analogous to cardiovascular interventions of the past few decades. Conservative medical management of these intestinal conditions can fail or result in extended hospital admissions and poor quality of life, while current operative management can be fraught with complications and death, especially in high-risk patients with prior abdominal surgeries.
