Advancements in both surgical and less invasive techniques have improved our ability to safely screen, diagnose, and treat disease within the abdomen and pelvis. Endoscopy, endoscopic retrograde cholangiopancreatography, interventional radiology, and laparoscopy have revolutionized the art of diagnosis and treatment of gastrointestinal tract disorders over the past 30 years. Key advances include direct inspection of bowel lumen, biopsy of suspected disorders, and treatment of abnormalities, including removal of mucosal lesions, dilatation, and stent placement of strictures. Radiologists must be aware of the complications resulting from a variety of gastrointestinal, radiologic, and surgical procedures. This article reviews the imaging findings related to incorrectly placed stents, intestinal and esophageal perforations, misplaced instruments, and fluid collections secondary to interventional procedures.
