Özet
A 62-year-old man was admitted with hematemesis. He had been diagnosed to have hepatitis B-related cirrhosis 4 months earlier, and had not undergone esophagogastroduodenoscopy (EGD) previously. He had no history of dysphagia. During intubation with an endoscope (GIF Q-150, Olympus, Japan), resistance was encountered at the upper esophageal sphincter, and a diverticulum was noted at this level. Although very difficult, the endoscope was passed gently into the esophagus. EGD was performed and esophageal varices with red spots were diagnosed. Endoscopic variceal ligation (EVL) was decided; however we considered that repeated esophageal intubation would be impossible with an affixed band ligation set. Thus, a guidewire (0.035 inch; Boston-Scientific, Marlborough, MA, United States) was inserted into the stomach via the working channel under endoscopic vision, and the endoscope was withdrawn over the guidewire. An endoscopic band ligator device (Speedband Superview Super 7 Multiple Band Ligator, Boston-Scientific) was fixed to the endoscope. Following that, the endoscope was loaded with a catheter (standard type catheter, Boston-Scientific) beside the handle of the multiple band ligator ([ Fig. 1 ]). Thereafter, the guidewire was inserted into the leading end of the catheter and pushed until it passed out from the working channel of the endoscope. The catheter was first advanced to the stomach. The endoscope was then pushed forward over the catheter into the distal esophagus ([ Fig. 2 ]). After complete withdrawal of both catheter and guidewire, EVL was performed successfully. The second EVL session was carried out using the same method 4 weeks later. Fig. 1 View of the loaded catheter and the handle of the ligation device.

Several methods have been reported to intubate the esophagus using an overtube [ 1 ], a hydrophilic guidewire [ 2 ], or a catheter [ 3 ]; however no data exist on the EVL procedure in Zenker’s diverticulum. Affixation of an endoscopic band ligator device will make esophageal intubation more difficult and dangerous. On the other hand, the present case shows that if the diagnostic EGD is able to intubate the esophagus, with the guidance of a guidewire and catheter, the EVL procedure is safe and effective in patients with Zenker’s diverticulum.
