Diamond-shaped versus side-to-side anastomotic duodenoduodenostomy in laparoscopic management of annular pancreas in children: a single-center retrospective comparative study.
BACKGROUND
Annular pancreas is a rare congenital disorder that requires surgical management once diagnosed. Diamond-shaped and side-to-side duodenoduodenostomy are both popular worldwide nowadays in the surgical management of annular pancreas. Here we present our experience with laparoscopic management of annular pancreas in the last 5 years and compare the clinical results of the diamond-shaped versus side-to-side anastomotic techniques.
METHODS
Fifty-two patients diagnosed with annular pancreas who underwent duodenoduodenostomy at our medical center between January 2016 and April 2021 were included in the study. Forty-four patients underwent laparoscopic diamond-shaped duodenoduodenostomy (DS group) and eight underwent laparoscopic side-to-side duodenoduodenostomy (STS group). Clinical data, including surgical indices and early outcomes after surgery, with at least 19 months of follow-up, were collected and analyzed.
RESULTS
Of the 52 patients, 61.5% were prenatally diagnosed, and vomiting was the most common clinical manifestation after birth. The operative time and bleeding volume were 187.5 [interquartile range (IQR), 150-228)] min and 2 (IQR, 2-5) mL in the DS group, compared to 175 (IQR, 155-270) min and 2 (IQR, 2-4.25) mL in the STS group (P=0.89 and 0.32 respectively). The mean time from surgery to initial oral feeding and full oral feeding was 6 (IQR, 4-10) and 12 (IQR, 10-15) days in the DS group, compared to 8 (IQR, 4.75-11.25) and 14.5 (IQR, 13-16.75) days in the STS group (P=0.61 and 0.46 respectively). The mean hospital stay was 16 (IQR, 14-19) and 20 (IQR, 17.75-26) days in the DS and STS groups respectively (P=0.13). No severe complications such as anastomotic leakage, anastomotic stenosis, reoperation or unsuspected rehospitalization were noted in either group. Feeding intolerance was revealed in six cases in the DS group and two cases in the STS group, and there was no significant difference between the two groups (P=0.50).
CONCLUSIONS
Both laparoscopic diamond-shaped and side-to-side techniques showed good clinical results in treating annular pancreas. The surgical technique, trans-anastomotic tube and early feeding are not likely to increase the risk of postoperative feeding intolerance.

The annular pancreas (AP) is an uncommon congenital anomaly, characterised by a circumferential envelope in the second portion of the duodenum. In recent years, some genetic component has been found in the etiology. A newborn full-term male, weighing at 1910 g at birth, had a history of intrauterine growth restriction and diagnosis of tetralogy of Fallot, Down syndrome and congenital hypothyroidism. Duodenal membrane is suspected after persistent postprandial vomiting and abdominal distension; his abdomen was distended, hyperresonant and soft. The gastroduodenal series showed data compatible with a duodenal membrane so exploratory laparotomy was performed, finding the pancreas completely wrapping the second portion of the duodenum, so a diamond-shaped-duodenoduodenostomy anastomosis was performed. The AP should be considered, especially in male neonates with postprandial vomiting, abdominal distension, who show some other congenital anomaly, and in the abdominal X-ray, the sign of the double bubble is observed.

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.

An 18-year-old woman with annular pancreas and duodenal duplication presented with recurrent acute pancreatitis and underwent a resection of duodenal duplication. However, the patient experienced recurrent abdominal pain after resection. Abdominal computed tomography and magnetic resonance imaging showed a dilatation of the peripheral pancreatic duct and stenosis and malformation of both the Wirsung's and Santorini's duct due to multiple stones. The modified puestow procedure was performed. The main pancreatic ducts in the body and tail were opened, and the intrapancreatic common bile duct was preserved. A Roux-en-Y pancreatico-jejunostomy was performed for reconstructing the pancreaticobiliary system after removing the ductal protein plug. The patient experienced no abdominal pain, no significant elevation of the serum amylase and lipase levels, and no stone formation during the 2 years of follow-up. This procedure is considered to be beneficial for pediatric patients with chronic pancreatitis due to annular pancreas and duodenal duplication.

Review
Malrotation and midgut volvulus are surgical emergencies that commonly occur within the first month of life. The classic symptom is acute bilious vomiting, while nonspecific symptoms such as recurrent abdominal pain may be present in older children. Malrotation can be associated with duodenal obstruction caused by an abnormal peritoneal fibrous band or congenital anomalies, such as an annular pancreas or a preduodenal portal vein. Volvulus can lead to bowel ischemia and a life-threatening condition, thus prompt and accurate diagnosis is crucial. Diagnosis can be made through upper gastrointestinal series, ultrasonography, and CT, with ultrasonography being preferred as a screening tool due to its rapid and accurate diagnosis, without radiation exposure, in children. This pictorial essay discusses the key imaging findings and diagnostic approaches for malrotation and midgut volvulus, as well as diagnostic pitfalls based on actual cases.

INTRODUCTION
Annular pancreas is an uncommon congenital abnormality characterized by a ring of pancreatic tissue around the duodenum descending part. It is exceptionally rare in adults and is increasingly detected after the investigation of symptoms caused by its consequences, which include recurrent pancreatitis, duodenal stenosis at the site of the annulus, or duodenal or gastric ulcers. In this study, we present a case report of symptomatic annular pancreas in an adult patient.
PRESENTATION OF CASE
A 23-year-old woman hospitalized for epigastric pain and recurrent vomiting. Radiological examination was consistent with an annular pancreas. At operation, a partial 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 gastrojejunostomy was performed and she was discharged after 8 days with good recovery.
CONCLUSION
Because annular pancreas in adults is a rare clinical scenario, it should be included in the differential diagnosis of adult patients with gastrointestinal obstructive symptoms for a prolonged period of time, given that surgical intervention has a reliable outcome.

BACKGROUND
Annular pancreas (AP) is a rare congenital abnormal rotation of the pancreas. AP rarely occurs in adults. Pancreatic tumors and ampullary tumors are related to AP, so the discovery and treatment of AP are essential.
CASE SUMMARY
This study investigated the clinical manifestations, imaging features, complications, and treatment of six patients diagnosed with AP at the Department of Hepatobiliary and Pancreatic Surgery, First Hospital of Jilin University from January 2010 to June 2020. There were four males and two females, with an average age of 56.00 ± 9.86 years old. In this study, abdominal pain and jaundice were the main clinical manifestations. Imaging can show the "crocodile jaw sign" or "double bubble sign".
CONCLUSION
For patients with duodenal or biliary obstruction, physicians should give priority to AP when imaging examinations suggest that the duodenum is wrapped with tissue similar to the density of the pancreas. Symptomatic patients should actively undergo surgical treatment.

BACKGROUND AND AIM
Pancreaticobiliary anomalies are rare and often present with cryptic signs and symptoms, thus delaying appropriate treatment.
METHODS
Endoscopic retrograde cholangiopancreatography (ERCP) was used to define pancreaticobiliary anomalies. A retrospective review was performed of 5522 ERCPs conducted at a tertiary care center from 1972 to 2015.
RESULTS
There were 249 (4.5%) patients with pancreaticobiliary anomalies, including 179 patients with pancreas divisum (PD), 44 patients with choledochal cyst (CC) (Todani's classification Type I: extrahepatic cyst 31, Type III; choledochocele 9, Type V: Caroli's disease 4), 20 patients with anomalous pancreaticobiliary ductal union (APDU), and 6 patients with other abnormalities. Of 179 patients with pancreas divisum, 8 (4.5%) required minor sphincterotomies for multiple unexplained acute pancreatitis. Of the 31, 15 (48%) Type I CC patients underwent an operation. In patients with Type III CC (choledochocele), seven of the nine were treated by endoscopic sphincterotomy, and two patients were treated by surgery. Four patients with Type V CC (Caroli's disease) were managed nonoperatively. Of the 20 patients with APDU, 8 (40%) required operative intervention. Six patients were found to have other anomalies: two with pancreas bifidum, one with a duplication of the gallbladder, one with a cystic duct diverticulum, one with an annular pancreas, and one with an abnormal cystic duct origin. These patients were treated based on their etiology.
CONCLUSION
Pancreaticobiliary anomalies are rare and can be defined using ERCP. The appreciation of these abnormalities is important for the proper diagnosis and treatment of these rare biliary and pancreatic disorders.

The annular pancreas (AP) is a congenital anomaly of the pancreas that can cause acute abdominal pain and vomiting after birth. However, the genetic cause of AP is still unknown, and no study has reported AP in patients with 17q12 duplication. This study retrospectively analyzed the next-generation sequencing (NGS) data of individuals from January 2016 to June 2020 for 17q12 duplication. To identify the function of the key gene of in the 17q12 duplication region, human mRNA was microinjected into LiPan zebrafish transgenic embryos. A total of 19 cases of 17q12 duplication were confirmed. AP was diagnosed during exploratory laparotomy in four patients (21.1%). The other common features of 17q12 duplication included intellectual disability (50%), gross motor delay (50%), and seizures/epilepsy (31.58%). The ratio of the abnormal pancreas in zebrafish was significantly higher in the overexpression models. In conclusion, we first reported AP in patients with duplication of the 17q12 region, resulting in the phenotype of 17q12 duplication syndrome. Furthermore, our zebrafish studies verified the role of the gene in pancreatic development.

PURPOSE
The aim of the study is to assess the value of saline-aided ultrasound (US) in diagnosing congenital duodenal obstruction (CDO).
METHODS
The neonates with CDO were enrolled in this study, including the neonates confirmed with annular pancreas (AP) by operation, the neonates confirmed with duodenal atresia, the neonates confirmed with duodenum web, and the neonates confirmed with malrotation. Pertinent data were recorded, including the US features, intraoperative findings, and surgical procedures. The methodology of this study is a diagnostic test study which means the US feature is the test and the intraoperative finding is the gold standard.
RESULTS
A total of 95 neonates were enrolled, including 33 neonates with AP, 6 neonates with duodenal atresia, 29 neonates with duodenum web, and 27 neonates with malrotation. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the hyperechogenic band for the detection of AP were 78.8% (26/33), 90.3% (56/62), 81.2% (26/32), 88.8% (56/63), and 86.3% (82/95), respectively. The sensitivity, specificity, NPV, and accuracy for the detection of duodenal atresia were 0% (0/6), 100% (89/89), 93.6% (89/95), and 93.6% (89/95), respectively. The sensitivity, specificity, PPV, NPV, and accuracy for the detection of duodenum web were 100% (29/29), 100% (66/66), 100% (29/29), 100% (66/66), and 100% (95/95), respectively. The sensitivity, specificity, PPV, NPV, and accuracy for the detection of malrotation were 100% (27/27), 100% (68/68), 100% (27/27), 100% (68/68), and 100% (95/95), respectively.
CONCLUSION
Saline-aided US is a feasible tool to diagnose CDO.
