Abstract: Annular pancreas (AP) is a rare congenital anomaly. Coexisting malignancy has been reported only in a few cases. We report what is, to the best of our knowledge, the first case in the English literature of duodenal adenocarcinoma in a patient with AP. In a 55-year old woman with duodenal outlet stenosis magnetic resonance cholangiopancreatography showed an aberrant pancreatic duct encircling the duodenum. Duodenojejunostomy was performed. Eight weeks later she presented with painless jaundice. Duodenopancreatectomy revealed a duodenal adenocarcinoma, surrounded by an incomplete AP. Thus, co-existent malignancy with AP can be present without obstructive jaundice and without being visible through preoperative diagnostics.

Abstract: Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the descending part of the duodenum. It is one of the few congenital anomalies of the gastrointestinal tract which can produce symptoms late in life. In adults, the factors initiating symptoms are recurrent pancreatitis, duodenal stenosis at the site of the annulus, or duodenal or gastric ulceration. We report a new case involving a 24-year-old woman hospitalised for epigastric pain, nausea and vomiting. Radiological examination was consisted with an annular pancreas. At operation a complete obstruction of the second part of the duodenum was found, caused by an annular pancreas, no other congenital anomaly of the intra-abdominal organs was noted. A gastroenterostomy was performed.

Abstract: annular pancreas is a rare developmental anomaly where the head of the pancreas surrounds the second part of the duodenum like a ring. this may cause the duodenal constriction, obstruction, peptic ulcers and other complications. we saw a classic case of annular pancreas. the head of pancreas surrounded the second part of duodenum completely. however there was no narrowing of the duodenum. the case may be of importance for gastroenterologists, surgeons and radiologists.

Abstract: Two cases of annular pancreas in adults are being reported. In the first case, a middle aged lady presented with duodenal obstruction and gastric ulcer. Anterior H. S. V. with posterior truncal vagotomy and isoperistaltic duodeno-jejunostomy relieved her symptoms. In the second case, a young girl presented with duodenal obstruction, severe wasting and gross dehydration. She had an uneventful recovery following a duodeno-jejunostomy.

Abstract: Objective: Annular pancreas is an uncommon cause of duodenal obstruction in children. In this study, the clinical, radiological, and prognostic findings related to this disorder over a 12-year review period were analyzed.Materials and Methods: A retrospective review of 22 patients with annular pancreas who were treated with surgical repair between April 1998 and February 2010 was performed at two different pediatric surgical units. Presenting symptoms, associated anomalies, radiological findings, the type of surgery performed, postoperative outcomes, and complications were analyzed.Results: Twenty-two patients were identified. Thirteen of the 22 patients (59.1%) were born prematurely, 11 patients (50%) had low birth weight, 2 patients (9.1%) had very low birth weight and 1 patient (4.5%) had extremely low birth weight. The mean birth weight was 2285.23±675.12 g. (970-3300). All patients presented with vomiting, which was bilious in nine (40.9%). Nine patients (40.9%) had chromosomal anomalies. Corrective surgery consisted of duodenoduodenostomy in 9 patients (40.9 %), duodenojejunostomy in 9 patients (40.9%), and gastrojejunostomy in 4 patients (18.1%). Fourteen of the 22 patients have survived (63.6%). The causes of death were combinations of sepsis, pneumonia, brain hemorrhage, and cardiac anomaly. Conclusion: Infants with annular pancreas associated with duodenal obstruction were often born prematurely and/or had low birth weights; many had cardiovascular anomalies. Annular pancreas associated with duodenal obstruction correlated strongly with the trisomy 21 karyotype among the chromosomal anomalies, as did duodenal atresia. The oral feeding tolerance time was nearly the same for all patients regardless of the surgical procedure used.

Abstract: La obstrucción intestinal duodenal es frecuente en el recién nacido como causa de oclusión, puede ser completa (atresia duodenal) secundaria a un trastorno de revacuolización de la luz intestinal o por una rotación irregular del páncreas hacia la derecha del duodeno. Presentamos a un recién nacido con edad gestacional de 35.4 semanas, conteo de Apgar de 8-8 puntos, que nace con signos de shock hipovolémico secundario a una anemia aguda por desgarro del corión, con una Encefalopatía Hipóxica Isquémica(EHI). Desarrolló posteriormente una intolerancia digestiva con abundante residuo gástrico, valorándose una oclusión intestinal incompleta alta, posiblemente por una estenosis duodenal. Se le realizan radiografías de abdomen simple de pie apoyándose la sospecha clínica por la presencia de imagen típica "en doble burbuja", se realizó laparotomía exploradora encontrando en el acto quirúrgico una Estenosis Duodenal secundaria a un Páncreas Anular. Es egresado a los 45 días de vida con buen peso corporal y reflujo gastroesofágico grado III como complicación. Actualmente se encuentra bajo seguimiento ambulatorio multidisciplinario y en franca evolución satisfactoria. Duodenal intestinal obstruction is frequent in newborn as a cause of occlusion, it can be complete (duodenal atresia), secondary to a disorder of revacuolization of the intestinal lumen, or due to an irregular rotation of pancreas towards theright of duodenum. A newborn with a gestational age of 35.4 weeks, apgar score of 8.8 who was born with signs of hypovolemic shock secondary to an acute anemia caused by chorion tear with an Ischemic Hypoxic Encephalopathy, who subsequently deveoped a digestive intolerance with abundant gastric residue. An incomplete intestinal occluson was assessed - possibly as a result of a duodenal stenosis - simple abdominal X - rays was performed, supporting clinical suspicion because of the presence of a typical image in "double bubble". An exploratory laparatomy was carried out, finding in surgery a Duodenal Stenosis secondary to an annular Pancreas. The patient was discharged from the hospital 45 days after being born with a good weight and as complication a gastroesophageal reflux of third degreee. Currently the patient undergoes ambulatory-multidisciplinary follow-up, and is making a satisfactory progress.

Abstract: Annular pancreas is a rare congenital abnormality. This entity can rarely be symptomatic. Patients can present with gastrointestinal obstruction or acute pancreatitis. We report a case with a rich iconography, of an annular pancreas discovered intraoperatively. A 46- year-old woman was operated with the diagnosis of acute cholecystitis with common bile duct stones. At operation, a strip of pancreatic tissue (2 cm) completely encircled the second duodenum. Open cholecytectomy with choledocotomy and stones extractionwas done. Postoperatively, she developed an acute pancreatitis. The post-operative cholangiography showed the annular duct surrounding the second duodenum. Annular pancreas is rare. Symptoms may occur in newborn children. In adults, annular pancreas discovering is radiological or intra operatively.

Abstract: We report here a child who presented with features of small gut obstruction which were attributed to a foreign body impacted in the intestine. At surgery, an annular pancreas was detected and the foreign body was found to be lodged in the distended proximal duodenum.The reported case highlights the fact that an impacted radio-opaque foreign body in a child should warn the pediatrician to the possibility of an obstructive congenital anomaly.Small round or oval objects that enter the stomach nearly always pass uneventfully through the gastrointestinal tract without requiring intervention. The retention of foreign objects within the duodenum is suggestive of partial obstruction, usually of congenital origin [1-3]. We describe a child presenting with features of high intestinal obstruction where retention of such an object led to the discovery of congenital duodenal stenosis producing partial obstruction.A 32-month-old boy presented with a history of intermittent vomiting over the previous 15 months. The vomitus was generally non-bilious but occasionally bilious. The parents also noticed intermittent distension of his abdomen which subsided after vomiting. The symptoms seemed to commence after the child had swallowed a metallic pendant which was coin-shaped and about 12 mm in diameter; at the time of swallowing, the child was about 17 months old. He underwent repeated plain upright radiographs of the abdomen to localize the foreign body and to determine whether it had been passed. However, these continued to detect the foreign body. The last plain radiograph (Figure 1) of his abdomen showed the foreign body to be located in the right lower quadrant and it was surmised that the intestinal obstruction was due to impaction of the foreign body in the region of the terminal ileum. The child's parents were therefore advised that their child needed to undergo surgery for relief of the obstruction. However, a review of the plain upright radiograph of the abdomen showed the pres
