First experience using a wireless oesophageal pH monitoring system in children in Hong Kong: three case reports

Twenty-four–hour pH monitoring is indicated for evaluation of gastroesophageal reflux symptoms in children, as well as part of a preoperative work-up for those who require long-term nasogastric tube feeding or a gastrostomy. Its use is nonetheless restricted by the need to keep a nasal catheter in place for at least 24 hours. This can cause great discomfort and may be poorly tolerated by children, especially those with behavioural issues. Wireless pH monitoring can improve patient satisfaction and the overall sensitivity of diagnosing gastroesophageal reflux (<a href="https://www.hkmj.org/system/files/hkmj2411824-fig-1.jpg">Fig 1</a>). Despite its rising popularity among adults, its use has been limited in children. This report documents the first experience in Hong Kong of a wireless oesophageal pH monitoring system in children with gastrointestinal symptoms and feeding problems.<br>
