HYPOTHESIS Infants with rotational abnormalities of the midgut mesentery are at high risk for gastroesophageal reflux disease (GERD) and for sudden infant death (SID) from GERD. DESIGN A survey of the prevalence of GERD and the risk factor for SID from GERD in a case series of infants treated for congenital anomalies that include intestinal malrotation. Eighty-one (89%) of the infants studied...

CMAJ 2000;162(9):1315-7 The case A 6-month-old girl presents to her pediatrician with lethargy; she has been vomiting and the vomit is bile stained. She is admitted to hospital for tests. Plain radiographs of the abdomen and barium enema examination are normal. Results of an upper gastrointestinal (GI) study are suspicious for, but not diagnostic of, intestinal malrotation. The patient improves...

The authors presented a case of left paraduodenal hernia as a cause of closed loop small bowel obstruction in an elderly patient. Internal hernias are a rare cause of intestinal obstruction. Paraduodenal hernias are the most frequent especially left sided, which are believed to be the result of malrotation of the midgut during embryonic period. The clinical presentations varied, ranging from as...

A 40-year-old woman presented with small bowel obstruction caused by an internal hernia through Peterson's defect. The patient was known to have midgut malrotation (MM) and also had laparoscopic Roux-en-Y gastric bypass for morbid obesity 6 years prior. An open revision of Roux-en-Y gastric bypass was performed as a result of ischemia of alimentary limb. She made a slow but uneventful recovery ...

Meckel's diverticulum (MD) is a true congenital diverticulum that is remnant by incomplete obliteration of the omphalomesenteric duct. It is the most common congenital anomaly of the gastrointestinal tract, with an estimated prevalence of 2% (0.3% to 3% in autopsy studies). About 90% of MD occurs within 100 cm of the ileocecal valve. A primary malignant tumor arising within an MD is extremely u...

Midgut malrotation and incomplete rotation are common causes of neonatal intestinal obstruction. At end of 10 week of intrauterine life, cecum will be placed in subhepatic region temporarily and descends to right lower quadrant by eleventh week. Arrest of cecum in subhepatic region or undescended cecum is a rare congenital anomaly of mid gut. Usually, it remains asymptomatic and is diagnosed in...

This is an analysis of 6 patients with enteric duplications seen over an 8 year period at the Department of Pediatric Surgery, Dongsan Medical Center. They were all males but one. All duplications were cystic, and single except one. Locations of duplications were in the duodenum in one patient, in the jejunum in one, and in the terminal ileum in four. Five of the 6 patients were seen within 1 y...
