Duodenum inversum

This report describes the case of a previously healthy 16-year-old patient who initially presented with emesis of unknown etiology that was refractory to standard medical interventions. The initial imaging revealed duodenum inversum, a rare anatomic abnormality that provided additional diagnostic complexity to this case. Though the final diagnosis was found to be functional vomiting, this case gives an instructive review of this rare anatomic abnormality, the significant effects it may cause, and how making a diagnosis of exclusion can be challenged by unusual turns in an otherwise straightforward presentation...

Duodenum inversum is a rare congenital anomaly of unknown aetiology characterised by the proximal duodenum travelling posteriorly and superiorly prior to crossing midline. Clinical presentations include epigastric pain, nausea, and abdominal distension. It can be associated with duodenitis, acute pancreatitis, peptic ulcer disease and functional biliary obstruction. In this case report, we discuss a 77-year-old male who presented with hematemesis and epigastric pain secondary to duodenitis, for which he had a CT scan of the abdomen which demonstrated duodenum inversum...

Duodenum inversum, or inverted duodenum, is a rare congenital disorder resulting in an abnormal position of the third and/or fourth portions of the duodenum. Most patients are asymptomatic, but others can experience pain, nausea, vomiting, peptic ulcer disease, pancreatitis, and even intestinal obstruction. In this case, we report a patient who presented with acute abdominal pain and vomiting. He was diagnosed with duodenal volvulus and obstruction due to duodenum inversum. After failing nonoperative management, the patient was successfully treated with surgical resection...

BACKGROUND AND METHOD: Feeding problems and gastrointestinal disorders are the most common anomalies in people with Down syndrome (DS) and have a significant impact on their daily life. This study lists the various anomalies on the basis of 504 references selected from a PubMed search in October 2018. RESULTS: The anomalies are grouped into three categories: anatomical anomalies: duodenal atresia and stenosis (3.9%), duodenal web and annular pancreas; aberrant right subclavian artery (12% of children with DS with cardiac anomaly); Hirschsprung's disease (2...

Gastro-oesophageal reflux disease (GORD) is a very common paediatric disorder and the majority of patients are treated successfully by primary care physicians. Two infants aged 2 months with GORD which did not respond to conventional medical management are reported; they were diagnosed with duodenum inversum. The first infant failed medical management and required Nissen's fundoplication to control his symptoms. The second infant improved on maximizing medical management without the need for a surgical procedure...

Duodenum inversum is a rare congenital malformation defined by a duodenum which travels superiorly and then posteriorly prior to crossing the midline above the pancreas. It is often confused with other, more common, anomalies of intestinal rotation. We present a case of duodenum inversum diagnosed incidentally in a one-month old infant with Trisomy 21 during evaluation for reflux disease. Due to an inability to definitively rule out malrotation, the diagnosis was confirmed with a diagnostic laparoscopy. We discuss available literature concerning this rare anatomic anomaly as well as provide recommendations for diagnosis and treatment...

BACKGROUND: Duodenum inversum is an often unrecognized anomaly of duodenal rotation/fixation at upper gastrointestinal (UGI) contrast study because the duodenojejunal junction appears normally located. OBJECTIVE: This anomaly is important to diagnose because it may result in obstructive gastrointestinal symptoms. CONCLUSION: We describe a case of duodenum inversum mimicking superior mesenteric artery (SMA) syndrome that improved after surgical therapy...

PURPOSE: To analyze difficult diagnostic cases of malrotation to identify features crucial to accurate diagnosis. MATERIALS AND METHODS: The authors reviewed the radiographs and records of 81 symptomatic children who underwent surgery with a preoperative diagnosis of malrotation. Eleven had subtle rotational abnormalities (potential false-negative examinations), and 12 had false-positive upper gastrointestinal examinations. RESULTS: Subtle signs of malrotation included unusual redundancy of the duodenum to the right of the spine and location of the duodenojejunal junction (DJJ) medial to the left pedicle...

A case of Morbus Crohn is reported in which duodenum inversum was diagnosed incidentally. The importance of this rotational anomaly in the context of modern imaging methods is discussed.

Duodenum inversum is usually associated with chronic abdominal pain which is of unknown etiology. Incomplete rotation of the bowel may be associated with this anomaly. An unusually high incidence of pancreatitis, elevated bilirubin, and hypoalbuminemia was noted in this series of nine patients.
