Congenital duodenal obstruction is a common cause of bowel obstruction. It is relatively easy to diagnose in the neonatal period. However, if the obstruction is due to a duodenal diaphragm, diagnosis may be delayed until later in infancy or even adulthood, depending on the size of the aperture in the diaphragm. Congenital duodenal obstruction may be associated with other gastrointestinal and biliary anomalies. The association of a duodenal diaphragm and a partial annular pancreas is a rare clinical entity. We present an unusual case of late presentation of duodenal diaphragm with partial annular pancreas in a 10-year-old girl with a 3-month history of abdominal distension and vomiting. The plain abdominal X-ray showed the classic picture of a double bubble. The CT images showed narrowing of the third duodenal portion and dilatation of the stomach and duodenum. The pancreatic tissue incompletely surrounded the second part of the duodenum. Intraoperatively, both the duodenal diaphragm and the partial annular pancreas were confirmed. Excision of the diaphragm and duodenoplasty were performed. A duodenal diaphragm should be suspected in patients with a history of abdominal distension and vomiting, even in late childhood. Associated gastrointestinal and biliary anomalies should always be excluded.

Zhejiang Da Xue Xue Bao. Yi Xue Ban =... Jul 2019To analyze clinical manifestations, diagnosis and treatment of annular pancreas in neonates.
OBJECTIVE
To analyze clinical manifestations, diagnosis and treatment of annular pancreas in neonates.
METHODS
Clinical data of 114 neonates with annular pancreas admitted in the Children's Hospital of Zhejiang University from January 2009 to December 2018 were reviewed. The demographic parameters (gestational age, birth weight), clinical manifestations, onset time, results of antenatal examination, associated anomalies, radiological findings, operations, postoperative complications were analyzed.
RESULTS
One hundred and two cases were examined by abdominal echography, in which 68 cases showed duodenal obstruction, 4 cases showed annular pancreas. Plain abdomen X-ray examination performed in 113 cases before operation, 76 cases presented double-bubble sign, 12 cases presented single-bubble sign and 5 cases had high-position intestinal obstruction. Upper gastrointestinal radiography (UGI) was performed in 103 cases, which suggested duodenal obstruction in 102 cases. Operations were performed in all cases, of which 69 cases were operated under laparoscopy including 1 case converted to open laparotomy. The mean fasting time after surgery was (7.8±2.7) d, and the mean length of hospital stay was (16.9±10.1) d. Five patients had postoperative complications. The incidence of postoperative complications in antenatal abnormal group was lower than that in the antenatal non-abnormal group (<0.05); the average fasting time in laparoendscopic surgery group was shorter than that in traditional laparotomy group (<0.05).
CONCLUSIONS
Neonates with recurrent vomiting early after birth should be highly suspected to have annular pancreas. The fetal chromosome examination should be performed with abnormal antenatal screening. Surgery is the only effective way to diagnose and treat annular pancreas, and laparoscopic surgery could be the first choice for experienced doctors.

Annular pancreas is an uncommon congenital anomaly which is a rare cause of congenital duodenal obstruction. It is normally identified during the neonatal period, but may also be identified in adolescence or adulthood. This diagnosis is often overlooked in adult patients who present with symptoms suggestive of duodenal obstruction. We present a case of AP detected in a 23-year-old man, with complaints of continuous vomiting and abdominal discomfort over the last 6 months. An upper gastrointestinal study revealed a constricted second part of the duodenum. A computed tomography scan revealed a complete ring of pancreatic tissue around the second part of the duodenum. Diagnostic and therapeutic surgery decompresses the external obstruction. The patient had an early post-operative activation. No specific guidelines and protocols exist about the management of such cases. Given the rarity of this congenital anomaly, presenting with chronic partial duodenal obstruction, and its successful surgical treatment, have prompted us to report the case along with a brief review of literature about the subject.

Prenatal Diagnosis Oct 2020To retrospectively analyze the imaging findings of fetal intestinal obstruction diagnosed by MRI and compare with postnatal surgery findings.
OBJECTIVE
To retrospectively analyze the imaging findings of fetal intestinal obstruction diagnosed by MRI and compare with postnatal surgery findings.
METHODS
MRI data of 3346 pregnant women were retrospectively analyzed; we found 47 cases of suspected fetal small intestinal obstruction. Twenty-nine underwent postnatal surgery.
RESULTS
We identified one case of jejunal obstruction secondary to perforation, five annular pancreas, 10 duodenal stenoses, four jejunal stenoses, five jejunal atresias, two ileal atresias, four intestinal volvulus, and four intestinal malrotations. We further found four cases of duodenal stenosis with intestinal malrotation (two cases also showed volvulus). On fetal MRI, annular pancreas and duodenal obstruction manifested as a "double bubble." Jejunal stenosis appeared as a "triple bubble." Jejunal and ileal atresia mainly manifested as proximal dilatation with high signal on T1WI. Intestinal volvulus showed a sausage-like intestinal distortion and mixed signals on T1WI and DWI sequences. Intestinal malrotations were characterized as abnormal duodenal morphology. We missed two malrotations; one jejunal obstruction was misdiagnosed.
CONCLUSION
Prenatal MRI can accurately determine the degree of intestinal obstruction and help qualitatively diagnose its possible etiology according to changes in MRI signals in multiple sequences, providing guidance for prenatal counseling.

Our purpose is to illustrate the radiological aspects of the annular pancreas as an etiology of duodenal obstruction in infants. We report the case of a 4-month-old girl, who was admitted to our department with postprandial vomiting evolving since birth. The initial examination found a severely dehydrated patient. Abdominal ultrasound showed gross dilatation of the stomach and duodenum, it also showed pancreatic tissue surrounding the duodenum, suggesting a diagnosis of annular pancreas as the cause of the duodenal obstruction. Post-contrast abdominal CT showed the gastric and duodenal dilatation, and a ring of pancreatic tissue surrounding uncompletly the second portion of the duodenum. The patient underwent a bypass surgery which consisted in a duodeno-duodenostomy with simple post-operative follow-up and no recurrence of digestive symptoms. Annular pancreas is a rare pathology to be sought in neonatal obstruction. A good knowledge of radiological semiology is essential for a good diagnostic approach. However, surgery is the only effective way to diagnose and treat this pathology.

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.

PURPOSE
According to current protocol, the separation of pancreatic head and body is performed at the level of superior mesenteric vein (SMV). Previous data indicate that the resection plane should be modified in portal annular pancreas. We presumed that the optimal line of pancreatic resections could also be different in other cases. Our aim is to simulate pancreatic resections in different planes and find the optimal resection line with the minimum number of cut vessels.
MAIN METHODS
25 abdominal vascular corrosion casts were prepared, the aorta and the portal vein were cannulated. CT scans were taken on the casts, and specific planes were reconstructed simulating different resection lines. The total amount of cross sections of vessels were calculated in the different planes.
RESULTS
In our series, the optimal plane is the SMV in 11/25, 2 cm left in 10/25, 1 cm left in 4/25, 1 cm right in 1/25 and 2 cm right in none of our cases. The group of left sided extension contain more than half of the cases. With left sided resections, the cut surface of the vessels may be lowered to even 29% compared to the SMV plane.
CONCLUSION
Our study revealed that pancreatic resections should be extended to the left side of the SMV in more than half of our cases. Therefore, the resection plane should be determined by preoperative imaging methods. Using DICOM viewer with multiplanar reconstruction, the resection planes can be simulated in clinical practice, which would reduce the risk of postoperative bleeding.

OBJECTIVES
We aimed to describe the clinical characteristics of pediatric patients with pancreatitis caused by pancreaticobiliary malformation and to evaluate the efficacy and safety of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of the disease.
METHODS
Medical records of pediatric patients with pancreatitis related to pancreaticobiliary malformation diagnosed by ERCP and treated in our hospital between April 2008 and December 2020 were retrospectively reviewed. Clinical manifestations, laboratory indicators, genetic testing results and imaging findings including MRCP were collected.
RESULTS
Of the 148 patients with pancreaticobiliary malformation-related pancreatitis, 90 (60.8%) had pancreaticobiliary maljunction (PBM), 52 (35.1%) had pancreatic divisum (PD), and six (4.1%) had annular pancreas (AnnP). Compared with the PD group, patients with PBM were younger (P < 0.001), and were more likely to have jaundice (P < 0.001) and fever (P = 0.034). Genetic mutation was found in 51.6% of patients with PD, 50.0% with AnnP, and 15.0% with PBM. Diagnostic rate of PBM, PD, and AnnP using MRCP was 46.7%, 15.4%, and 100%, respectively. In total, 87.8% of patients had symptomatic improvement after endoscopic treatment. ERCP-related complications were observed in 28 out of the 260 procedures, including post-ERCP pancreatitis (7.7%), infection (2.3%), and gastrointestinal bleeding (0.8%).
CONCLUSIONS
PBM should be considered when jaundice and fever occur in pediatric patients. Genetic testing is recommended for those with PD and AnnP. The role of MRCP is limited in identifying pancreaticobiliary malformation in children. ERCP is effective and safe for the diagnosis and treatment for pediatric pancreatitis caused by pancreaticobiliary malformation.
