A 59-year-old man was admitted with a 1-year history of recurrent diarrhea and abdominal pain. Colonoscopy performed the previous year showed multiple colonic ulcers, which were confirmed by pathology. Repeat colonoscopy demonstrated a sigmoid ulcer with stenosis that could not be traversed with an adult colonoscope.
The stenosis was successfully traversed with a transnasal gastroscope (GIF-XP260N, diameter 6 mm, length 1050 mm; Olympus, Tokyo, Japan), which could reach the terminal ileum. Multiple ulcers were seen in the terminal ileum, ascending colon, transverse colon, and sigmoid, whereas the mucosa of the descending colon and rectum were normal. The transnasal gastroscope could also enter the lumen of the appendix, and showed that the appendiceal orifice was edematous ([Fig. 1 a]). The appendix mucosa was smooth without erosion or ulceration ([Fig. 1 b]). The entire appendiceal lumen could be visualized, including the tip of the appendix ([Fig. 1 c]). The interior folds of the appendix were also clearly seen by the transnasal gastroscope ([Fig. 1 d, ] [Video 1]).

Video 1 A novel application of the transnasal gastroscope for endoscopic imaging of the appendiceal lumen.
Qualität:
Endoscopic imaging of the appendix has been described by others using SpyGlass (Boston Scientific, Marlborough, Massachusetts, USA) [1] [2]. However, SpyGlass is expensive, requires a colonoscope, and provides poorer image quality. This is the first report of successful use of a transnasal gastroscope to examine the entire appendiceal lumen and capture high quality images and a good video. We suggest that a transnasal gastroscope could be used when examination of the appendix is required. The transnasal gastroscope could also be useful in the future for some endoscopic surgery procedures such as endoscopic retrograde appendicitis therapy [3].
