Double-Contrast Upper Gastrointestinal Radiography: A Pattern Approach for Dias of the Stomach
Abstract
The double-contrast upper gastrointestinal ries 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 discusd. A pattern approach for the diagnosis of gastric abnormalities will also be prented, focusing on abnormal mucosal patterns, depresd lesions, protruded lesions, thickened folds, and gastric narrowing.
This article prents a pattern approach for the diagnosis of dias 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, depresd lesions (erosions and ulcers), protruded lesions (polyps, submucosal mass, 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 ha
s a fixed configuration created by the greater length of the longitudinal muscle layer on its greater curvature. The lesr curvature of the stomach is suspended from the retroperitoneum by the
hepatogastric ligament, a portion of the lesr 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.

sheetmusicAreae Gastricae
The mucosal surface of the stomach
consists of flat polygonal-shaped tufts of
mucosa, known as areae gastricae,
parated by narrow grooves (6,7). The
areae gastricae are recognized on
double-contrast studies as a reticular
network of barium-coated white lines
when barium fills the grooves between
the mucosal tufts (Fig 3). Individual
mucosal tufts of areae gastricae
normally have a diameter of 2–3 mm in
the gastric antrum and of 3–5 mm in the
gastric body and fundus (Fig 3) (6,8).
Areae gastricae are detected on
double-contrast studies in nearly 70% of
patients and are obrved with greater
frequency in the elderly (8,9).

Comparison of Histologic Anatomy with Macroscopic Anatomy
A basic understanding of the histologic anatomy of the stomach is helpful for understanding peptic ulcer dia, as well as other gastric abnormalities (5,10). The stomach contains veral types of mucosa: cardiac-type mucosa, body/fundic-type mucosa, and
antral/pyloric-type mucosa. Gastric foveolae (or pits) are conical depressions in the mucosal surface that communicate with gastric glands (4,10). The glands are long, straight, and tightly packed structures. The foveolae in all parts of the stomach are lined by surface foveolar mucous cells. The cardiac-type mucosa compris a short (1 cm in length) gment of the gastric mucosa adjacent to the gastroesophageal junction (4). The distinguishing feature of the body-type mucosa is the prence of parietal and chief cells in the glands. The parietal cells produce hydrochloric acid and intrinsic factor, and the chief cells produce proteolytic enzymes. No parietal or chief cells are found in antral-type mucosa. The surface foveolar mucous cells line both antral pits and glands.

对胃组织学结构有⼀个基本的学习有助于我们更好的理解消化性溃疡及其它胃功能紊乱性疾病(5,10)。胃包括⼏种不同类型的黏膜:贲门型黏膜、胃体/胃底型黏膜,以及幽门/胃窦型黏膜。胃黏膜表⾯有些圆锥形的凹陷,叫做胃⼩凹(胃⼩点),它与胃腺相沟通(4,10)。腺体形直体长,且为严密包裹的结构。在胃的各个部分,胃⼩凹均由表层⼩凹黏膜细胞连接⽽成。贲门型黏膜由⼀个邻近胃⾷管连接部只有1厘⽶长的胃黏膜⼩段构成(4)。胃体型黏膜最明显的特征是其胃腺中有壁细胞和主细胞。壁细胞分泌盐酸和内因⼦,主细胞分泌蛋⽩⽔解酶。胃窦型黏膜中⽆壁细胞和主细胞。胃窦胃⼩凹和胃腺由胃⼩凹黏膜细胞相连。
胃体型黏膜移⾏贯穿于解剖学上的胃底和胃体,并沿着胃⼤弯延伸⾄胃窦部。胃窦型黏膜则沿着胃⼩弯从幽门到⾓切迹移⾏贯穿于整个胃窦部,但在胃⼤弯处只移⾏⼀⼩部分。所以,组织学上分型把胃分为体型及窦型黏膜,和解剖学上及放射学上把胃分为底部、体部、窦部是没有相关性的。
curvature. Thus, the histologic division of the stomach into body- and
antral-type mucosa does not correlate with the anatomic and radiologic division of the stomach into fundus, body, and antrum (5).
The transition zone between body- and antral-type mucosa is a line that extends from the incisura angularis to the distal greater curvature. The transition zone migrates proximally with age, extending
progressively higher on the lesr curvature. Peptic ulcers frequently develop on the lesr curvature at the transition zone (Fig 4).
