Reviewer’s report
Title: Pneumatosis Cystoides Intestinalis: A case report and literature review
Version: 2 Date: 04 Sep 2019
Reviewer: Cheng-Maw Ho
Reviewer's report:
The authors had addressed the comments appropriately. However, there are grammar and typo errors 
that needs further language editing before publication. 
For example,
Page 11 Line 48 "At the same time, cobined with...", it should be "combined" with
Page 12 Line 35 "Surgery is not an absolute indication to treat PCI". Maybe you want to express " 
Surgical intervention is not absolutely necessary to treat PCI".
Page 13 Line 31 "PCI is a relatively inexperienced disease for clinicians..".  A better way to express is "  
PCI is relatively unfamiliar to inexperienced clinicians".
