Usefulness of a novel narrow-diameter endoscope for endoscopic balloon dilation of esophageal strictures
Esophageal stricture is a narrowing of the esophageal lumen, often causing esophageal obstruction [1] [2]. Dilation of strictures by endoscopy using balloon dilation is indicated to restore the patency of the esophageal lumen [3]. We present the case of a 55-year-old Japanese man who presented with chest discomfort. Upper gastrointestinal endoscopy (UGE) revealed a full-circumferential ulcer in the mid-portion of the esophagus, without obvious dysmorphic epithelium ([Fig. 1]). In the absence of obvious malignancy on biopsy, proton pump inhibitors (PPI) were prescribed for severe reflex esophagitis. On day 36 of PPI treatment, the patient reported aggravation of esophageal stasis with solid food. On UGE, an esophageal stricture was observed and was treated by endoscopic esophageal dilatation (EED) using a 12-mm-diameter balloon (CRE PRO GI Wireguided Balloon; Boston Scientific, USA). EED needed to be repeated 2 weeks later. On this second occasion, the stricture was assessed using an ordinary 9.8-mm-diameter upper gastrointestinal endoscope (EG-840T; Fujifilm, Japan), as used on the previous occasion. The endoscope could not be passed through the region of stricture due to scarring in the area of the ulcer ([Fig. 2]). Therefore, we selected to use a narrow-diameter, 7.9-mm upper gastrointestinal endoscope (EG-840TP; Fujifilm). Although the narrow-diameter endoscope could not be passed through the region of stenosis, it could be safely inserted into the esophageal inlet, providing a more detailed assessment of the stricture compared to the 9.8-mm diameter endoscope. The narrow-diameter endoscope includes a 3.2-mm hole for endoscopic forceps, which allowed us to perform EED using a 13.5-mm-diameter balloon (CRE PRO GI Wireguided Balloon) without difficulty ([Fig. 3]; [Video 1]). After EED, the endoscope could be passed through the region of stenosis without resistance. Based on our experience, we propose that the novel narrow-diameter endoscope is a potential first-choice endoscope for safe and reliable EED.
