Oesophageal and gastric scintigraphy evaluates the function of the gastrointestinal system including variables such as oesophageal transit and gastric emptying (GE). Some variables are known to change after bariatric surgery. In patients that have symptoms of pain or nausea after bariatric surgery, oesophageal and gastric scintigraphy plays an important role in determining the nature of symptoms and is necessary for adequate treatment. However, literature on reference values in the bariatric population are scarce. At this moment, quantitative evaluation of the scintigraphy cannot be performed and conclusions are based on visual interpretation. There is a need for a standardised scintigraphy protocol for the population that underwent bariatric surgery taking into account the changed anatomy and physiology. Then, reference values that describe the oesophageal transit and GE assessed using scintigraphy have to be determined.
Study Type
OBSERVATIONAL
Enrollment
50
oesophageal and gastric emptying
Rijnstate Hospital
Arnhem, Gelderland, Netherlands
reference values for RYGB and GS patients
gastric emptying (T1/2 \[min\], retention \[%/min\], caloric emptying \[cal/min\], GE curve over time)
Time frame: 2-3 years
to describe SPECT/CT images and determine its benefit for anatomical correlation in asymptomatic (reference) and symptomatic population.
Time frame: 2-3 years
to define reference values for RYGB- and SG-patients for oesophageal scintigraphy after bariatric surgery using an optimised protocol;
transit time \[min\], emptying rate \[%/min\]
Time frame: 2-3 years
to explore the correlation of GE and oesophageal transit, and weight loss results or symptoms, using prospective data from this study and retrospective data from symptomatic patients and similar studies previously
Time frame: 2-3 years
