Abstract
The major consequence of portal hypertension is bleeding, particularly from esophageal varices (Fig. 23.1) [1]. Digestive bleeding has also been found to occur from gastric sources (Fig. 23.2) [2] and colorectal sources [3, 4]. The recognized existence of portal hypertensive gastropathy [5] and portal hypertensive colopathy [6] suggests that the small bowel may also present endoscopic lesions related to portal hypertension. In fact, Thiruvengadam and Gostout [7] reported in 1989 on three patients presenting with blood loss, who had diffuse erythema and scattered petechiae in the stomach and in the duodenum and jejunum. Since then, the small bowel, previously considered to be the most difficult segment of the gut to study, has come to be easily explored using new endoscopic methods such as capsule endoscopy and double-balloon enteroscopy. This development in the field of small bowel endoscopy has allowed significant progress in the study of small bowel diseases, including the implications of portal hypertension.
The work was first published in 2006 by Springer Medizin Verlag Heidelberg with the following title: Atlas of Video Capsule Endoscopy.
