Reviewer’s report
Title: 
Cholangiocarcinoma presenting as dysphagia and misdiagnosed as
gastritis: A case report
Version: 
1 
Date: 
02 Jul 2021
Reviewer's report:
This case seems to be an ectopic bile duct cancer in the stomach, but why did
this surgery perform such a procedure? The CT findings showed a
circumferential thickening of the wall in the cardia and fornix of the stomach. I
guess that the lesion usually requires total gastrectomy, including the lower
esophagus. Was the tumor completely removed by this surgical procedure, or
was the tumor left in the abdominal cavity? Even if this lesion was an
heterotopic cholangiocarcinoma in stomach, it is clinically an advanced gastric
tumor of the upper stomach, so what is the stage of the tumor in pathological
findings? The author must describe the pathological stage. Since the pathological
stage was not described, it cannot be determined whether this surgical procedure
was appropriate. It seems difficult to publish as a case report just because the
pathological findings was rare.
