Congenital Congenital Chorioretinitis duodenal obstructions are a group of inborn conditions that cause obstruction of the lumen of the duodenal segment of the small intestine Small intestine The small intestine is the longest part of the GI tract, extending from the pyloric orifice of the stomach to the ileocecal junction. The small intestine is the major organ responsible for chemical digestion and absorption of nutrients. It is divided into 3 segments: the duodenum, the jejunum, and the ileum. Small Intestine: Anatomy, impeding the passage of food and gastric juices. The condition may have intrinsic etiologies, such as duodenal atresia Atresia Hypoplastic Left Heart Syndrome (HLHS) (most common) and/or extrinsic etiologies, such as an annular Annular Dermatologic Examination pancreas Pancreas The pancreas lies mostly posterior to the stomach and extends across the posterior abdominal wall from the duodenum on the right to the spleen on the left. This organ has both exocrine and endocrine tissue. Pancreas: Anatomy. The hallmark of duodenal obstruction is bilious vomiting Vomiting The forcible expulsion of the contents of the stomach through the mouth. Hypokalemia. The condition can be diagnosed through prenatal or postnatal ultrasound. Associated anomalies, including congenital Congenital Chorioretinitis heart disease, are common. Treatment includes fluid resuscitation Resuscitation The restoration to life or consciousness of one apparently dead. . Neonatal Respiratory Distress Syndrome and surgical duodenoduodenostomy.

Common causes of polyhydramnios include fetal anomalies, gestational diabetes, multiple gestations, and congenital infections. Patients are often asymptomatic but may present with dyspnea, extremity swelling, or abdominal distention. Polyhydramnios
