Background And Aims:
Pyloric sphincter impedance planimetry (endoscopic functional lumen imaging probe [EndoFLIP]) is increasingly used to evaluate for pyloric dysfunction in patients with gastroparesis. Traditionally, the impedance planimetry catheter is placed through the mouth and alongside a gastroscope; however, this method can be technically challenging and time-consuming. This study aims to present a step-by-step guide for an alternative and more efficient technique: pyloric impedance planimetry catheter placement using an extra-large-channel therapeutic gastroscope with a through-the-scope approach.
Methods:
We present a case of a 49-year-old female patient with idiopathic gastroparesis who underwent successful pyloric sphincter assessment with an 8-cm impedance planimetry catheter using an extra-large 6-mm therapeutic channel gastroscope (GIF-XTQ160; Olympus Medical Systems, Tokyo, Japan) with a through-the-scope approach.
Results:
This article and accompanying video review the technique for inserting an 8-cm impedance planimetry catheter using an extra-large 6-mm channel therapeutic gastroscope. The catheter was successfully and efficiently placed using a through-the-scope catheter placement technique.
Conclusions:
Using a through-the-scope technique with an extra-large-channel therapeutic gastroscope for pyloric sphincter assessment with impedance planimetry is an effective and efficient approach.
