胃肠道梗阻是在腹壁可见到相应的轮廓、称胃型或肠型。由于该部位蠕动加强，

Gastrointestinal obstruction is seen in the abdominal wall with a corresponding outline, called gastric or intestinal type. Peristaltic waves can be seen in the abdominal wall due to increased peristalsis at this site. The peristaltic wave of the stomach starts from under the left costal margin, slowly advances to the right, and disappears under the right rectus abdominis. The intestinal type and peristaltic waves of small bowel obstruction are more common in the umbilicus. In intestinal paralysis, the peristaltic wave disappears.

Gastrointestinal obstruction is the corresponding contour that can be seen in the abdominal wall, which is called gastric type or intestinal type. As the peristalsis of this part is strengthened, peristaltic waves can be seen in the abdominal wall. The peristaltic wave of the stomach starts from under the left costal margin, advances slowly to the right, and disappears under the right rectus abdominis. Intestinal type and peristaltic wave in small intestinal obstruction are more common in the umbilicus. Peristaltic wave disappeared during intestinal paralysis.

Gastrointestinal obstruction is the corresponding contour that can be seen in the abdominal wall, which is called gastric type or intestinal type. Because the peristalsis of this part is strengthened, peristalsis waves can be seen in the abdominal wall. The gastric peristalsis wave starts from under the left costal margin, slowly advances to the right, and disappears under the right rectus abdominis muscle. Intestinal type and peristalsis in small intestinal obstruction are mostly found in navel. When the intestine is paralyzed, the peristalsis wave disappears.
