What symptom does rectum atresia have?

summary

During the development of intestinal tract in embryo, part of the intestine stopped developing during the process of re cannulation, resulting in complete or partial obstruction of intestinal cavity. Complete occlusion is atresia and partial occlusion is stenosis. During the development of intestinal tract in embryo, part of the intestine stopped developing during the process of re cannulation, resulting in complete or partial obstruction of intestinal cavity. Complete occlusion is atresia and partial occlusion is stenosis. It can occur in any part of the intestine, but the ileum is the most common, followed by the duodenum, and the colon is rare. It is one of the common causes of neonatal intestinal obstruction. What symptom does rectum atresia have? Let's talk about my views.

What symptom does rectum atresia have?

Symptom 1: vomiting is the most prominent manifestation of congenital intestinal atresia and intestinal stenosis. Frequent vomiting occurs within a few hours to 1-2 days after birth, with a large amount of vomit. In most cases, the vomit contains bile, and in a few cases, the vomit is old bloody. Intestinal atresia or stricture can be caused by intestinal jejunal insufficiency in the solid phase of embryonic development.

Symptom 2: no normal meconium excretion. Or only a small amount of gray green jelly sample was discharged. There was no abdominal distension in high intestinal atresia or stricture, but the upper abdomen was slightly full; Abdominal distension was obvious in patients with low intestinal atresia or stenosis, even intestinal type. Severe vomiting can cause dehydration, acid-base imbalance and electrolyte disorder.

Symptom 3: X-ray plain film of abdomen shows that there are 2-3 fluid levels in stomach and duodenum, but jejunum does not inflate; In low atresia or severe stenosis, most of the enlarged intestinal flexure and fluid level could be seen. The blood supply disorder of a certain part of the intestines during the fetal period, such as intestinal volvulus, intussusception, fecal peritonitis and adhesive strangulation, intestinal perforation, internal hernia, mesenteric vascular malformation, results in the blood supply disorder of a certain part of the intestines, which leads to the pathophysiological process of intestinal necrosis, absorption, repair and so on.

matters needing attention
