Double contrast gastrointestinal radiology with endoscopic correlation

Double contrast radiography of the colon has been available to the radiologist for decades. Within the last few years, however, there has been a resurgence in this technique. Improvement in apparatus and barium preparations has resulted in notably superior radiographs. A detailed look at the mucosal lining of gut has been provided. A need then arose for interpretation of these surface patterns as well as a technique to reproduce these images consistently. The author and his collaborators have answered this need with Double Contrast Gastrointestinal Radiology With Endoscopic Correlation. Detailed in 17 chapters is a method for double contrast examination of the entire gastrointestinal tract. Technical and interpretative information is described; radiographic reproductions are excellent. The chapter entitled "Principles of Double Contrast Diagnosis" is particularly useful in presenting basic concepts of interpretation that apply to double contrast examination of any region of the gut. Pathology presented has been limited to disease states that are most identifiable by this technique. The Japanese method of double contrast examination of the stomach has been modified by the author. This technique, when combined with hypotonic agents, produces striking radio¬ graphs of the duodenum. The small bowel examination has always been an area of difficult radiographic analysis. A protocol for the small bowel enema examination is presented with examples of normal as well as pathological states. Because of the inaccessibility of the majority of the small bowel to the endoscope, any technique to improve diagnostic accu¬ racy is most welcomed. Regarding endoscopy, the author shares his personal endoscopie ex¬ perience. The endoscopie photographs juxtaposed with the double contrast radiography are most dramatic. (The more subtle findings are highlighted with arrows and line diagrams.) Normal anatomy, pathological conditions, and artifacts simulating dis¬ ease are presented. The chapters on the colon deal with
