Annular pancreas is a rare congenital anomaly in which a thin band of pancreatic tissue partially or completely surrounds the duodenum. It is challenging to diagnose due to its variable clinical presentation. Approximately two-thirds of patients have no symptoms in their lifetime, and most symptomatic cases are seen in neonates and infants. Symptomatic adult patients present with upper gastrointestinal symptoms, such as epigastric pain, vomiting, and postprandial fullness associated with gastric outlet obstruction. Complications associated with annular pancreas include peptic ulcer disease, pancreatitis, pancreatic head carcinoma, and biliary obstruction. Annular pancreas is also a rare cause of upper gastrointestinal bleeding in adults, but it should be considered as one of the differential diagnoses in patients presenting with a peptic ulcer and duodenal stricture. Here, we report the case of a 60-year-old man who presented with melena and was subsequently diagnosed with an annular pancreas.

VACTERL Syndrome affects multiple body systems and can include various anomalies of the Vertebral column, Anus and/or rectum, heart (Cardiac), Tracheo-Esophagus, kidneys (Renal), and Limbs. Patients with VACTERL syndrome are at increased risk of having a congenital duodenal obstruction that may be extrinsic in the form of an annular pancreas or intrinsic in the form of duodenal atresia, stenosis or web. Simultaneous presentation of both the annular pancreas and duodenal web is a rare clinical entity and typically presents in neonates. However, late presentation of annular pancreas combined with a duodenal web is exceedingly uncommon. We present a case of late diagnosis of annular pancreas with duodenal web resulting in an entrapped ingested foreign body.

Duodenal stenosis and atresia are some of the most common forms of congenital bowel obstruction. The gold standard approach to treatment is duodenoduodenostomy, while rare, gastrojejunostomy and duodenojejunostomies may still be used. We report a case of a 7-year-old male presenting with annular pancreas with duodenal stenosis that was diagnosed at birth as primary duodenal atresia and repaired by gastrojejunostomy with a Braun enteroenterostomy. Through successful reoperation with dual duodenojejunostomy and subsequent management, we treated the sequelae of the initial repair, including megaduodenum. Regions of duodenal obstruction must have direct anastomotic repair to prevent subsequent issues related to dysmotility. Otherwise, further surgical intervention and long-term medical management, such as the novel strategy reported, may be necessary.

Review
Congenital anomalies of the liver, biliary tree and pancreas are rare birth defects, some of which are characterized by a marked variation in geographical incidence. Morphogenesis of the hepatobiliary and pancreatic structures initiates from two tubular endodermal evaginations of the most distal portion of the foregut. The pancreas develops from a larger dorsal and a smaller ventral outpouching; emergence of the two buds will eventually lead to the fusion of the duct system. A small part of the remaining ventral diverticulum divides into a "pars cystica" and "pars hepatica", giving rise to the cystic duct and gallbladder and the liver lobes, respectively. Disruption or malfunctioning of the complex mechanisms leading to the development of liver, gallbladder, biliary tree and pancreas can result in numerous, albeit fortunately relatively rare, congenital anomalies in these organs. The type and severity of anomalies often depend on the exact moment in which disruption or alteration of the embryological mechanisms takes place. Many theories have been brought forward to explain their embryological basis; however, no agreement has yet been reached for most of them. While in some cases pathological evaluation might be more centered on macroscopic evaluation, in other instances small biopsies will be the keystone to understanding organ function and treatment results in the context of congenital anomalies. Thus, knowledge of the existence and histopathological characteristics of some of the more common conditions is mandatory for every pathologist working in the field of gastrointestinal pathology.

Review
BACKGROUND
The annular pancreas is a rare congenital disorder of the pancreas first recognized in 1818. 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.
CASE PRESENTATION
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.
CONCLUSION
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.

The aim of our manuscript is to report of a successful perinatal outcome after treatment of acute polyhydramnios caused by duodenal atresia. A 34-year-old G3P1 was referred due to polyhydramnios in the 30th week of pregnancy. Ultrasound revealed polyhydramnios, amniotic fluid index (AFI) 28, and a double bubble sign that indicated duodenal atresia and dilatated oesophagus. In the 32nd week of gestation, the volume of amniotic fluid increases, AFI 35, along with symptoms of dyspnea and abdominal pain. Due to the clinical picture and the early gestational age, it was decided to perform an amnioreduction. In the 36th week of gestation cesarean section was performed. The baby was taken for exploratory laparotomy and found to have a simultaneous complete duodenal atresia and annular pancreas with associated dilated the first portion of the duodenum and the stomach. A side-to-side duodenoduodenostomy via single-layer hand-sewn anastomosis was performed over a transanastamotic feeding tube (TAFT). The postoperative course was uneventful. Amnioreduction is useful and safe in the treatment of acute polyhydramnios caused by duodenal atresia and thus has a significant role in prolonging gestation until fetal maturity.

RATIONALE
Portal annular pancreas (PAP) is a rare pancreatic anomaly characterized by portal vein encasement in the pancreatic parenchyma. Due to its rarity, PAP may often be missed on preoperative computed tomography (CT) review, and surgeons may face challenges in dealing with an unexpected intraoperative encounter with PAP. We documented 2 such intraoperatively diagnosed cases and illustrated their surgical management.
PATIENTS CONCERNS
In case 1, a 70-year-old man was found to have a 15-mm mass in the pancreatic body and dilatation of the peripheral main pancreatic duct on enhanced CT. Case 2 involved a 46-year-old woman with a history of familial adenomatous polyposis, and rectal cancer with a mass in the duodenal papilla.
DIAGNOSES
The patient in case 1 was diagnosed with resectable pancreatic cancer. In case 2, the patient was diagnosed with duodenal papillary carcinoma.
INTERVENTIONS
In case 1, the patient underwent distal pancreatectomy with lymph node dissection. In case 2, the patient underwent pancreaticoduodenectomy. Intraoperatively, PAP was observed in both cases. In case 1, after the usual transection at the right border of the portal vein, an additional dissection was performed on the dorsal pancreas using a powered linear stapler. In case 2, an additional section was made in the pancreatic body caudal to the cricoid pancreatic junction so that the pancreatic cross-section was oriented in 1 plane.
OUTCOMES
The patient in case 1 was discharged without complications. In case 2, although the patient had a grade-B pancreatic fistula (International Study Group of Pancreatic Fistula Classification), the patient recovered conservatively and was discharged without significant complications. In both cases, a retrospective review identified PAP in patients' preoperative CT images.
LESSONS
Both cases required ingenuity during pancreatectomy. Awareness about PAP and its management will enable surgeons to prepare for unexpected encounters with the condition. Moreover, surgeons (especially pancreatic surgeons) should consider the possibility of PAP while managing pancreatic anomalies to make appropriate treatment decisions.

Communicating bronchopulmonary foregut malformations (CBPFM) are extremely rare. We present a complex case of type IB CBPFM with esophageal atresia and distal tracheoesophageal fistula (EA/TOF), duodenal atresia/annular pancreas (DA/AP), and intestinal malrotation who underwent primary repair for EA/TOF on day 3. Bilious aspirates on day 8 prompted an upper gastrointestinal (GI) contrast revealing a duodenal obstruction and communication between the right lung lower lobe and the esophagus (T8-T9 level). DA/AP and malrotation were repaired by a gastrojejunostomy and Ladd's procedure. A repeat contrast swallow identified a 2nd communication from the esophagus into the right lower lobe (T5-T6 level) raising the suspicion of a recurrent TOF. Computed tomography (CT) thorax confirmed above findings with an anomalous blood supply to right lung. An exploratory thoracotomy identified a three-lobed lung. However, the lower lobe was enlarged and connected in two separate locations to the esophagus. The child recovered after the disconnection of the esophageal connections and partial right lower lobectomy. CBPFM are extremely rare anomalies requiring a high index of suspicion, use of an upper GI contrast series, and CT scans for diagnosis. The treatment of choice is resection of the affected lung and disconnection of the esophageal communications.

PURPOSE
We aimed to evaluate possible positive and negative effects of postoperative use of transanastomotic feeding tube (TAFT) in neonates operated for congenital duodenal obstruction (CDO).
METHODS
This is a retrospective study reviewing medical records of neonates operated for CDO during 2003-2020 and comparing postoperative feeding outcomes and complications in patients with and without TAFT. Approval from the hospital's data protection officer was obtained.
RESULTS
One hundred patients, 59% girls, were included, and 37% received TAFT. Mean birth weight and gestational age were 2628 (675.1) grams and 36.6 (2.4) weeks, respectively. Furthermore, 45% had no other malformations, and 36% had Down syndrome. Patient demographics were similar for TAFT and not-TAFT patients, except that not-TAFT neonates weighed median 335 g less (p = 0.013). The TAFT group got parenteral nutrition 2 days shorter (p < 0.001) and started enteral feeds 1.5 days earlier (p < 0.001) than the not-TAFT group. Fewer neonates with TAFT got a central venous catheter [65 vs 89%, (p = 0.008)]. In the TAFT group, 67% were breast fed at discharge compared to 49% in the not-TAFT group (p = 0.096).
CONCLUSION
Neonates with TAFT had earlier first enteral feed, fewer days with parenteral nutrition and fewer placements of central venous catheters.
