Congenital gastric muscularis defect?

summary

Congenital gastric muscularis defect refers to the defect of gastric muscularis caused by embryo development disorder. It is rare, often in the occurrence of gastric perforation after treatment, mostly in 3-5 days after birth that perforation occurs, mainly in the early neonatal, and mostly in premature infants. Congenital gastric muscularis defect?

Congenital gastric muscularis defect?

In the process of embryonic development, the gastric parietal ring muscle is the first to occur, starting from the lower end of the esophagus, and gradually developing to the gastric fundus and the greater curvature of the stomach. At the 9th week of embryo, the oblique muscle appears, and finally the longitudinal muscle forms. If there is a developmental disorder at a certain stage, it will lead to the defect of gastric muscularis.

In the perinatal period of respiratory disorders, hypothermia and hypoxemia, asphyxia before and after birth may lead to local ischemia, gastric wall blood circulation disorder, mucosal muscle layer damage, or excessive increase of gastric acid, which may lead to compensatory blood redistribution in the baby's body, increase the blood supply of brain, heart and other important organs, and significantly reduce the blood supply of stomach and intestine, resulting in gastrointestinal ischemia and necrosis.

Neonatal submucosa tissue is fragile, elastic fiber is underdeveloped, and it is easy to appear gastric dilatation. If the content of the stomach is delayed, sucking, sucking and crying when swallowing the air, the intragastric pressure will rise, resulting in gastric dilatation, and finally rupture of the gastric wall muscle layer defect.

matters needing attention

Congenital gastric muscularis defect is not easy to diagnose before perforation. The child is in good condition after birth, without obvious prodromal symptoms, and has a history of normal defecation. It usually occurs 3-5 days after birth. There are also individual cases as early as the second day or as late as the eighth day. Do a good job of health care during pregnancy to prevent premature delivery and intrauterine hypoxia; To prevent perinatal respiratory disorders, to prevent the occurrence of hypothermia and hypoxemia; Active treatment of various perinatal diseases to promote the rehabilitation of children.
