Annular pancreas
ICD-10 Q45.1 is a billable code used to indicate a diagnosis of annular pancreas.
Annular pancreas is a congenital anomaly characterized by the encirclement of the duodenum by pancreatic tissue, which can lead to obstruction of the duodenum. This condition arises during embryonic development when the ventral pancreatic bud fails to migrate properly, resulting in a ring of pancreatic tissue that constricts the duodenum. Clinically, patients may present with symptoms of gastrointestinal obstruction, including vomiting, abdominal distension, and failure to thrive. Diagnosis is typically made through imaging studies such as ultrasound or MRI, which can visualize the abnormal pancreatic anatomy. Surgical intervention is often required to relieve the obstruction and may involve resection of the abnormal pancreatic tissue or bypassing the obstructed segment of the duodenum. Annular pancreas is often associated with other congenital malformations of the digestive system, such as esophageal atresia, Hirschsprung disease, and imperforate anus, necessitating a comprehensive evaluation of the gastrointestinal tract in affected infants.
Pediatric documentation should include detailed birth history, presenting symptoms, and growth parameters. Documentation of any associated congenital anomalies is crucial.
Common scenarios include infants presenting with bilious vomiting, abdominal distension, and failure to thrive, necessitating imaging and surgical evaluation.
Special considerations include the need for multidisciplinary care involving pediatric surgeons and gastroenterologists, as well as the potential for long-term follow-up.
Genetic documentation should include family history of congenital anomalies, genetic testing results, and any syndromic associations.
Genetic counseling scenarios may involve discussing the risk of recurrence in future pregnancies and the implications of associated genetic syndromes.
Considerations include the potential for chromosomal abnormalities that may co-occur with annular pancreas, necessitating comprehensive genetic evaluation.
Performed to bypass the obstructed duodenum due to annular pancreas.
Surgical reports detailing the procedure and findings.
Pediatric surgical documentation must include pre-operative and post-operative assessments.
Common symptoms include bilious vomiting, abdominal distension, and failure to thrive in infants. These symptoms arise due to duodenal obstruction caused by the encircling pancreatic tissue.
