Usefulness of gastroesophageal reflux scintigraphy using the knee-chest position for the diagnosis of gastroesophageal reflux disease

Abstract

GER scintigraphy can detect gastroesophageal reflux with a high sensitivity in the KC position and might be a useful method in the screening and assessment of the severity of this disease. This method would be useful for the diagnosis of GERD in endoscopically negative patients.

Riser’s reflux - an eye-opening experience

“…Changing body position from supine (sleep) to upright (awake) may potentially precipitate riser’s reflux. This position change may result in increase in intra‐abdominal pressure, potentially leading to gastro‐oesophageal reflux 20,21 . However, our study demonstrated that riser’s reflux occurred in 42% of the patients, even if they remained recumbent after waking up in the morning.…”

“…This position change may result in increase in intra-abdominal pressure, potentially leading to gastro-oesophageal reflux. 20,21 However, our study demonstrated that riserÕs reflux occurred in 42% of the patients, even if they remained recumbent after waking up in the morning. Thus, it is likely that riserÕs reflux is more related to the discontinuation of the suppressive effect of sleep on gastro-oesophageal reflux.…”

Consensus of gastroesophageal reflux disease in Taiwan with endoscopy‐based approach covered by National Health Insurance

“…Traditional diagnoses of GERD, including endoscopy, manometry, and pH studies, may be cumbersome in some cases, such as in patients who have undergone total or proximal gastrectomy, those with nasogastric tube or gastrostomy, and children. Esophageal radiographic or scintigraphic studies can be an alternative choice to define the presence of GERD [44,45]. More specifically, radionuclide scintigraphy may provide important diagnostic clues under special conditions, and the reported sensitivities of esophageal scintigraphy in the diagnosis of GERD could be up to 76% [46,47].…”
