Birth outcomes of male and female patients with infantile hypertrophic pyloric stenosis--a population-based case-control study

Idiopathic Hypertrophic Pyloric Stenosis with Complete Ladd's Band: A Rare Association

A male infant aged 45 days presented with projectile nonbilious vomiting for 2 weeks. Ultrasound showed picture of idiopathic hypertrophic pyloric stenosis. Laparoscopic pyloromyotomy was done, but postoperative vomiting that was mainly nonbilious continued without improvement. After 4 days of persistent vomiting, laparoscopic exploration was done and complete pyloromyotomy was confirmed and malrotation with complete Ladd's band was found, then case converted to open laparotomy and Ladd's procedure was done. Postoperatively, vomiting stopped completely and baby began gradual feeding till reaching full feed. Despite that the presentation of concurrent Idiopathic Hypertrophic Pyloric Stenosis with malrotation is extremely rare; a formal laparoscopic abdominal exploration should be done as the first step before proceeding to pyloromyotomy.

Annular pancreas in China: 9 years' experience from a single center

To summarize the clinical characteristics, diagnosis, treatment and prognosis among 152 children with annular pancreas (AP). A retrospective review of 152 patients with AP who were treated with surgical repair between January 2009 and August 2017 was performed at our pediatric surgical units. Presenting symptoms, birth weight, radiological findings, associated anomalies, the type of surgery performed were analyzed. (1) 152 patients were identified, out of which 82 were males, and 70 were females; (2) the average birth weight of children with AP was less than that of healthy newborns. The birth weights of 5.4% premature infants were less than 1500 g; the birth weight of 17% full-term infants, 69% premature infants and 50% post-term infants were less than 2500 g. (3) 100 (66%) patients presented symptoms during neonatal period and 43 (28%) patients had duodenal obstruction diagnosed by prenatal ultrasound scan. (4) All cases were managed surgically by open laparotomy, and all patients were duly discharged. AP most commonly presents symptoms in early neonatal period. Infants with AP are associated with a higher rate of low birth weight, and it was because swallowed amniotic fluid could not be absorbed and impaired insulin secretion caused by abnormal pancreas. Ultrasonography, abdominal plain film and upper gastrointestinal series (UGI) are helpful, but cannot make the diagnosis, and surgery is the only effective way to diagnose and treat AP.
