Research Overview

The Surgical Research Group works on a number of surgical problems affecting children, including:

  1. Normal and abnormal descent of the testis, with the aim of understanding the mechanism and providing possible non-surgical treatment - Project Leader: John Hutson
  2. Normal and abnormal postnatal germ cell development, which is believed to be the key to preventing infertility and testicular cancer in men with previous undescended testes in childhood - Project Leader : Ruili Li
  3. The causes of intractable chronic constipation, and the development of novel investigations and novel treatments, including electrical stimulation - Project Leader: Bridget Southwell
  4. The cause of duodenal atresia, using a new knockout mouse with downregulation of FGF10 - Project Leader: Warwick Teague
  5. Novel treatments for colorectal disorders such as anorectal anomalies and Hirschsprung disease - Project Leader: Sebastian King
  6. Using state-of-the-art manometry to understand surgical problems in the gut, such as oesophageal atresia and Hirschsprung disease - Project Leader: Sebastian King
