Hypertrophic pyloric stenosis following repair of oesophageal atresia and tracheo-oesophageal fistula in a neonate.

BMJ Case Rep 2018 Sep 21;2018. Epub 2018 Sep 21.

Department of Pediatric Surgery, School of Medicine, Harran University, Sanliurfa, Turkey.

Development of hypertrophic pyloric stenosis (HPS) after a few weeks of repair of an oesophageal atresia (OA) and tracheo-oesophageal fistula (TOF) is a rare condition in early infancy. Although vomiting or feeding intolerance in operated cases of OA+TOF are attributed to oesophageal stricture, gastro-oesophageal reflux and oesophageal dysmotility, it may also be caused by HPS. Herein, we report a newborn infant who had OA and TOF operation on day 2 of life and diagnosed to have HPS at 15th day of age. Read More

Background: Evacuation of gastric content through a nasogastric tube, followed by rapid sequence induction, is usually recommended in infants undergoing pyloromyotomy. However, rapid sequence induction may be challenging, and is therefore controversial. Some anaesthetists regularly perform classical non-rapid induction technique, after blind aspiration of the gastric contents, although this aspiration may have been incomplete. Read More

The association of molybdenum cofactor deficiency and pyloric stenosis.

J Perinatol 2012 Nov;32(11):896-8

Division of Neonatology, Department of Pediatrics, Akdeniz University Medical School, Antalya, Turkey.

Molybdenum cofactor deficiency (MoCD) is a rare autosomal recessive disorder that may present during the neonatal period with intractable seizures. Co-existence of MoCD and pyloric stenosis is previously reported as a coincidence or common etiology. The etiology of the two conditions is unclear; however, reports demonstrate neuronal deficiency in both. Read More
