It is believed to result from faulty rotation of the ventral pancreatic bud in its course around the posterior aspect of the duodenal anlage. The duodenum is encircled and might be obstructed by normal pancreatic tissue. The management of the annular pancreas is still developing and under revision.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation:<\/jats:title>\n                    <jats:p>Six cases of neonatal intestinal obstruction secondary to the annular pancreas diagnosed, operated on, and involved in our study. Age, gender, maturity, age at referral, birth weight, clinical presentation, imaging findings, associated congenital anomalies, treatment, complications, and hospital stay were all studied. Polyhydramnios is found in 3 cases (50%). Down syndrome was diagnosed in one case. One patient has associated malrotation. Symptoms started earlier within the first 24 hours. Vomiting was bile stained in 4 cases (66.7%). Passing meconium, sometimes frequent, does not exclude the annular pancreas. Most patients show double bubbles sign on plain abdominal X-ray. All six neonates were treated with duodenoduodenostomy with excellent results. Survival was 100% and complications were minimum.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The annular pancreas, although rare, is an important cause of neonatal duodenal obstruction. The accurate diagnosis is usually performed during laparotomy. Vomiting may contain bile or not, furthermore, passing meconium does not exclude this condition. The best and the excellent surgical option is diamond duodenoduodenostomy. This case series might be added to the registered cases of the annular pancreas to standardize the method of diagnosis and to define the best management.<\/jats:p>\n
