Response:

I appreciate Matsushita et al1 for their interest in my article "A rare cause of recurrent acute pancreatitis: duodenal intussusception by a fenestrated duodenum web."2 I agree with their assertion that endoscopically treating a fenestrated duodenum web, intraluminal duodenal diverticulum, would be less invasive and effective. Although we also considered endoscopic treatment for intraluminal duodenal diverticulum in this case, we could not determine the major duodenal papilla while performing EGD before surgery, thereby posing a high risk for endoscopic treatment.
