Iatrogenic Disorders of the Esophagus
Iatrogenic complications have increased as a result of the more aggressive, modern therapeutic and diagnostic interventions. This is as true for the esophagus as it is for other organs; in fact, in some respects the esophagus is more vulnerable than many other organs, as we shall see shortly. It is difficult to quantitate these complications precisely, but some idea of the scope of the problem comes from studying endoscopic and surgical data: endoscopic perforations occur in less than 1% of cases (1,2); postsurgical complication rates of 20%, 30%, or even 40% are not uncommon (2,3). It is thus likely that most radiologists will encounter some iatrogenic complication related to the esophagus in their daily practice. We will consider the potential complications under the following categories: those related to (a) endoscopy/biopsy, (b) surgery, (c) dilatation, (d) indwelling tubes, (e) drugs, (f) miscellaneous. We will not consider the important subject of radiation-induced complications here; they have been fully dealt with elsewhere in this volume.
