Transit-Pelletsmethod™ (formerly known as Abrahamsson Method), also known in some circles, as Sahlgrenska Method is a unique method designed for colonic transit studies. By using this Swedish method, physicians and radiologists can distinguish between normal, slow and rapid transit. Moreover it is possible to assess where the dysfunction in the colon is present.
The principle is that the patient swallows a fix dose of Transit-Pellets™ radiopaque markers for six days. On day seven, a single abdominal radiograph is taken. The patient colonic transit time is calculated as the mean oro-anal transit time (OATT, mouth-to-anus) in days of swallowed doses. This value is obtained base on the number of retained markers that are left and in which segment the markers are located.
