Double-Contrast Upper Gastrointestinal Radiography: A Pattern Approach for Diseases of the Stomach

Abstract

The double-contrast upper gastrointestinal series is a valuable diagnostic test for evaluating structural and functional abnormalities of the stomach. This article will review the normal radiographic anatomy of the stomach. The principles of analyzing double-contrast images will be discussed. A pattern approach for the diagnosis of gastric abnormalities will also be presented, focusing on abnormal mucosal patterns, depressed lesions, protruded lesions, thickened folds, and gastric narrowing.

This article presents a pattern approach for the diagnosis of diseases of the stomach at double-contrast upper gastrointestinal radiography. After describing the normal appearance of the stomach on double-contrast barium studies and the principles of

double-contrast image interpretation, we will consider abnormal surface patterns of the mucosa, depressed lesions (erosions and ulcers), protruded lesions (polyps, submucosal masses, and other tumors), thickened folds, and gastric narrowing. 上消化道双重对比造影：一种用于胃部疾病诊断的成像方法

摘要

上消化道双重对比造影系列是用于评估胃部结构性和功能性病变的一种极有价值的诊断方法。本文将回顾胃部正常解剖的影像学表现，探讨双重对比造影图像分析的原则。文中还介绍了一种胃部病变的诊断方法，该法侧重于观察异常的黏膜形状，凹陷性的病变、突出性的病变、增厚的黏膜皱襞和消化道的狭窄。

本文阐述了一种通过上消化道双重对比造影诊断胃部疾病的方法。在描述双重对比造影中胃的正常表现和双重对比造影图像分析原则后，我们将关注胃粘膜表面的异常形态，凹陷性的病变（糜烂和溃疡）、突出性的病变（息肉、黏膜下的块状物和其他肿块）、增厚的黏膜皱襞和消化道狭窄。

NORMAL STOMACH

Gastric Configuration and Rugal Folds The normal stomach is a J-shaped pouch that lies in the left upper quadrant (Fig 1). The stomach has a fixed

configuration created by the greater length of the longitudinal muscle layer on its greater curvature. The lesser curvature of the stomach is suspended from the retroperitoneum by the

hepatogastric ligament, a portion of the lesser omentum. The gastrosplenic ligament and gastrocolic ligament (ie, the proximal portion of the greater omentum) are attached to the greater curvature of the stomach. The gastric cardia is attached to the diaphragm by the surrounding phrenoesophageal

membrane.

Figure 1: Normal stomach. Double-contrast spot image of stomach with patient supine shows distal gastric body (B) and antrum (A). Greater curvature (white arrows) and lesser curvature (black arrows) are coated by barium. Rugal fold on posterior wall of gastric body is depicted as tubular, slightly undulating, radiolucent filling defect (black arrowheads) in shallow barium pool. Dense barium pool outlines contour (white arrowheads) of gastric fundus 正常胃 胃的外形与皱襞 正常的胃位于左上腹，形似J 型嚢袋（图1），胃固定的形态是由胃大弯上较长的纵向肌层形成的。胃小弯通过小网膜的一部分--肝胃韧

带悬挂在腹膜后腔内。胃脾韧带和胃结肠韧带（即大网膜近端）连于胃大弯上。胃贲门通过其周围的隔食管膜连于隔上。

图1： 正常胃：病人取仰卧位进行双重对比造影可以显示远端的胃体（B）和胃窦（A）。胃大弯（白色箭头所示）和胃小弯（黑色箭头所示）均覆盖有一层钡剂。射线透过钡池较浅的胃体部，能显示出胃体后壁的粘膜皱襞，呈管状、细小的波浪形的充盈缺损。胃底部（F）钡池稠密，勾勒出胃底的轮廓（白色小箭头所示）。胃底的粘膜表面和皱襞被稠密的钡池掩盖而不易看见，胃窦部无皱襞。
