Title: The Aggressive Surgical Treatment and Outcome of a Colon Cancer Patient with COVID-
19 in Wuhan, China
Version: 0Date: 08 Jun 2020
Reviewer: Shingo Tsujinaka
Reviewer's report:
I would like to show my appriciation for being shared with the authors' experiences in treating
colorectal cancer patient with SARS-Cov-2. This case report is worth publishing and very helpfulto all surgeons worldwide for decision-making process in surgery as well as pathologicalinvestigations in GI tract with SARS-Cov-2.
I have several concerns to this article, and the comments to the following points can be reflected to
the manuscript.
POINT 1:
The patient underwent surgery under continuous epidural anesthesia rather than generalanesthesia. Concerning the potential risk of aerosol infection, the authors still reommend epiduralanesthesia for major abdominal surgeries? or genenral anesthesia with specific considerations. Thepros and cons of epidural anesthesia with COVID-19 patients may be exhibited.
POINT 2:
Currently the surgical societies worldwide have published the guidelines and/or recommendations
in surgery for cancer patients. They are very concerned about surgical plume and droplets during
the operations. At the time of surgery for the presented case, did the authors use any evacuationsystem, specific filters, or energy device (e.g. use electrocautery with suction device, or not useultrasonic devices)??
POINT 3:
It is very interesting to know whether cancerous area are pathologically more vulnerable toCOVID-19 than non-cancerours tissues.
