One of the main causes of proximal bowel obstruction in neonates is congenital duodenal obstruction. It can be grouped by intrinsic and extrinsic factors and the presentation may differ depending on whether the obstruction is complete or partial. The intrinsic factors include duodenal atresia, duodenal stenosis, or duodenal web. The extrinsic factors include malrotation with Ladd's band, annular pancreas, anterior portal vein, and duodenal duplication. Malrotation may present with or without midgut volvulus. We are sharing a rare presentation of congenital duodenal obstruction with combined intrinsic and extrinsic causes, namely, duodenal stenosis with gastrointestinal malrotation in a neonate. The patient underwent successful exploratory laparotomy, corrective Kimura's procedure (duodenostomy), Ladd's procedure, and appendicectomy. Early recognition of signs and symptoms, prompt corrective surgery, and adequate optimization of metabolic components post-operatively are important to determine the decreased morbidity and mortality of neonates.

Journal of Pediatric Surgery Jun 2023The purpose of this study was to assess diagnostic accuracy and neonatal outcomes in fetuses with a suspected proximal gastrointestinal obstruction (GIO).
BACKGROUND
The purpose of this study was to assess diagnostic accuracy and neonatal outcomes in fetuses with a suspected proximal gastrointestinal obstruction (GIO).
METHODS
After IRB approval, a retrospective chart review was conducted on prenatally suspected and/or postnatally confirmed cases of proximal GIO at a tertiary care facility (2012-2022). Maternal-fetal records were queried for presence of a double bubble ± polyhydramnios, and neonatal outcomes were assessed to calculate the diagnostic accuracy of fetal sonography.
RESULTS
Among 56 confirmed cases, the median birthweight and gestational age at birth were 2550 g [interquartile range (IQR) 2028-3012] and 37 weeks (IQR 34-38), respectively. There was one (2%) false-positive and three (6%) false-negatives by ultrasound. Double bubble had a sensitivity, specificity, positive predictive value, and negative predictive value for proximal GIO of 85%, 98%, 98%, and 83%, respectively. Pathologies included 49 (88%) with duodenal obstruction/annular pancreas, three (5%) with malrotation, and three (5%) with jejunal atresia. The median postoperative length of stay was 27 days (IQR 19-42). Cardiac anomalies were associated with significantly higher complications (45% vs 17%, p = 0.030).
CONCLUSIONS
In this contemporary series, fetal sonography has high diagnostic accuracy for detecting proximal gastrointestinal obstruction. These data are informative for pediatric surgeons in prenatal counseling and preoperative discussions with families.

An annular pancreas is a rare anomaly of the pancreas, defined as pancreatic tissue that totally or partly encircles the duodenum, usually the descending portion. A 76-year-old man who was diagnosed with gastric cancer cT3N0M0 Stage IIB underwent laparoscopic distal gastrectomy with D2 lymph node dissection. Intraoperatively, the dorsal half of the duodenal bulb was seen to be half surrounded by the pancreas, and a non-typical annular pancreas was diagnosed. Because of the risk to the pancreas, it was considered impossible to perform anastomosis by a linear stapler as in the usual laparoscopic procedure. Therefore, we performed laparoscopically assisted distal gastrectomy and Billroth-I reconstruction using a circular stapler, and the surgery was completed without difficulties. His postoperative course was good despite the development of a pancreatic fistula, which was an International Study Group for Pancreas Fistula biochemical leak. Some APs can be diagnosed preoperatively, but the rarer subtypes such as ours are more difficult to visualize on imaging. In gastrectomy, it is both oncologically important and technically challenging to perform lymph node dissection around the pancreas. In this case with an especially proximal pancreas, a circular stapler was considered better suited for gastroduodenal anastomosis and required a broader field than that afforded by laparoscopy. A case of non-typical annular pancreas diagnosed during laparoscopic gastric surgery is described.

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.

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.

Annular pancreas (AP) is a congenital anomaly and a recognised cause of duodenal obstruction which can affect all age groups. It may manifest early in the neonatal period, but it may also have varied and often delayed symptoms. We report the case of AP in an 18-month-old girl with a long history of recurrent post-prandial non-bilious vomiting treated for a long time with the clinical diagnosis of gastroesophageal reflux. Upper gastrointestinal study was suggestive of partial duodenal obstruction and computed tomography revealed a complete ring of pancreatic parenchyma surrounding the second part of the duodenum. Diamond-shaped duodenoduodenostomy was achieved successfully and the post-operative period was uneventful. Although rare, AP must be kept in mind of any paediatric surgeon while confronted to symptoms of partial duodenal obstruction.

PURPOSE
The usefulness of endoscopic ultrasound (EUS) in pediatric populations has been recently appreciated; however, published studies on mini-probe EUS in the diagnosis of congenital esophageal stenosis (CES) or congenital duodenal stenosis (CDS) in pre-school patients remain scarce. This study aimed to report the utility of mini-probe EUS for the diagnosis of CES or CDS in pre-school patients based on the etiology.
METHODS
We retrospectively reviewed the medical records of pediatric patients with CES or CDS who underwent mini-probe EUS through the stenotic segments at our hospital between December 2006 and December 2021.
RESULTS
Five patients with CES and one with CDS were enrolled. The median age and body weight when EUS was performed were 12.5 months and 8.5 kg, respectively. Hypoechoic lesions were observed on EUS in three patients, which were assessed as cartilage; one patient had no hypoechoic lesion but had a focal thickness of the muscular layer. They were diagnosed with tracheobronchial remnants based on EUS. The full circumferential wall thickness of the esophagus was visualized in one patient with fibromuscular hypertrophy. The histopathological findings confirmed the diagnoses. In the patient with CDS, EUS findings revealed pancreatic parenchyma encircling the stenotic part of the duodenum. The preoperative diagnosis was annular pancreas. The patient underwent duodenoduodenostomy, and intraoperative findings confirmed the diagnosis.
CONCLUSION
Mini-probe EUS can be recommended as a feasible and safe technique for infants and toddlers. It can effectively diagnose CES or CDS based on etiology and can inform treatment strategies for pre-school patients.

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.

Congenital short bowel syndrome (CSBS) is a very rare gastrointestinal anomaly of unknown etiology. We report a case of a six-week-old male with CSBS who presented with features of intestinal obstruction and failure to thrive. The abdominal radiograph was suggestive of a central gasless abdomen, and a provisional diagnosis of malrotation of the gut with volvulus was considered. On exploration, the duodenum was hugely dilated with annular pancreas, which was not obstructing the duodenum. The length of the intestine was 20 cm from the duodenojejunal junction to the ileocecal junction. Duodenal web was ruled out. Total parenteral nutrition (TNP) was started postoperatively. Early and long-term parenteral nutrition and referral to specialist centers with intestinal rehabilitation programs have improved the overall outcome; however, the challenges are entirely different in developing countries.
