Gastrointestinal and peristaltic waves

Gastrointestinal and peristaltic wave examination refers to the diagnosis of the corresponding symptoms by examining the peristaltic waves generated by the gastrointestinal type. When the gastrointestinal tract is obstructed, the proximal end of the obstruction expands and presents a contour. If the peristalsis is enhanced at the same time, a peristaltic wave can be seen. The peristaltic wave refers to the wave motion that appears during the peristalsis of the intestines. Due to obstruction of the gastrointestinal tract, the gastrointestinal tract of the proximal obstruction is paroxysmal. Sometimes this peristaltic wave is from right to left, called the inverse peristaltic wave. When the small intestine is obstructed, the peristaltic wave is more common in the umbilicus, and the direction is different. Peristaltic waves can also be seen in the multi-partum and thinners with loose abdominal wall. When intestinal paralysis occurs, the peristaltic wave disappears. Intestinal peristalsis in the umbilicus is seen in small bowel obstruction. In severe obstruction, the umbilicus can be seen in a multi-layered trapezoidal intestine and a large intestine peristaltic wave. When the colon is obstructed, a large intestinal type appears in the periphery of the abdominal wall, and the cecum is swollen and spherical. Basic Information Specialist Category: Inspection Category: CT Applicable gender: whether men and women apply fasting: fasting Tips: Inappropriate people: In the elderly with thin or loose abdominal wall, extreme weight loss or multi-partum women often see peristaltic waves. Normal value The contours of the stomach and intestines and peristaltic waves are generally not seen in the abdomen of normal people. Clinical significance Abnormal results When the gastrointestinal tract is obstructed, the proximal end of the obstruction expands and presents a contour. If the peristalsis is enhanced at the same time, a peristaltic wave can be seen. Intestinal peristalsis in the umbilicus is seen in small bowel obstruction. In severe obstruction, the umbilicus can be seen in a multi-layered trapezoidal intestine and a large intestine peristaltic wave. In the case of colonic obstruction, a large intestine type appears in the periphery of the abdominal wall, and the cecum is swollen and spherical. Need to check the gastrointestinal infarction, gastrointestinal tract peristalsis. Precautions Check contraindications: the anus does not defecate, does not vent is a manifestation of complete obstruction of the intestine, but in the early stage of obstruction, the feces and gas remaining in the distal intestine of the obstruction can still be discharged, do not mistakenly believe that there is no obstruction. Requirements for inspection: When observing peristaltic waves, it is easier to see when viewed from the side or by tapping the abdominal wall with your hand. (1) When the abdomen is inspected, the abdominal exposure time should not be too long to avoid discomfort caused by cold. (2) Light should enter the field of view from the front side, and the side light is good for observing gastrointestinal and peristaltic waves. Inspection process (1) Stomach type and peristaltic wave: The peristaltic wave advances to the right from the left rib and disappears under the right rectus abdominis. This is a positive peristaltic wave. Reverse creep waves are sometimes seen. (2) intestinal type and peristaltic wave: often accompanied by high-pitched bowel sounds. Intestinal obstruction in the small intestine is located in the umbilicus, the direction of peristaltic wave is uncertain; the intestinal type and peristaltic wave are located in the peritoneal circumference when the distal end of the colon is obstructed. Not suitable for the crowd Inappropriate people: In the elderly with thin or loose abdominal wall, extreme weight loss or multi-partum women often see peristaltic waves.
