Title: Magnetic-Controlled Capsule Endoscopy Performance in Aging Patients
Version: 1 Date: 02 Dec 2022
Reviewer:  Konosuke Nakaji
Reviewer's report:
This is a retrospective study of magnetic controlled capsule endoscopy for the gastric lesion
(MCE) in China. Although several studies have already reported on the usefulness and safety
profile of MCE, this study focused on elderly patients, especially those over 80 years old.
Compared to the middle-aged group, the top results showed that although the transit times are
prolonged in the oldest, the overall visualizing scale is not statistically different, and findings
are more common in the most senior group. There are no severe adverse events in this study.
From this viewpoint, this study provided new helpful evidence in this field of study; therefore, it
is an exciting study for the coming “Old aged society” in Asia. However, there are some minor
concerns about this article. 1. The authors could provide an image of the system of MCE and each
part of gastric lesions for better understanding for general readers. 2. The authors could provide
more specific inclusion and exclusion criteria (e.g., pacemaker implantation) in the methods. It
is better to present the flow chart. 3. Could the authors be concerned about the HP infection and
state of atrophic gastritis? 4. The authors could present the detail of gastric tumors. Are these
included in early gastric cancer? Did they follow up by EGD, and what outcomes? The authors
could present their case examples.
