Reviewer’ s report
Title: Acute duodenal obstruction secondary to intussusception caused by the duodenal
diverticulum: A case report
Version: 0Date: 30 Apr 2020
Reviewer's report:
Thank you for introducing an interesting case.
The duodenal intussusception itself is also a rare disease, but cases caused by diverticulum were
more difficult to identify.As such, I think the objective diagnosis of intususception is important, as the authors havedescribed in this case report.In addition to the existing attached image, whether it is a true intususception or mucosal findingsby inverted diverticulum,it is thought that continuous CT images or other view CT findings of better picture quality shouldbe supplemented.
