PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: The authors report an interesting constellation of
conditions, with an emphasis on complex management strategies. It will be
useful for clinicians managing patients with CD.
I have highlighted some shortcomings in the next section.
REQUESTED REVISIONS: 
Style of writing
* "Under stable condition" needs rephrasing - suggest "in disease remission"
* Missing conjunctions - "to A rectovaginal fitula", "changed THE biologics",
"or A fistula tract", "combined WITH surgical", "arranged A transverse
colostomy", etc
* Fistula EXISTED - better to say persisted
* P6 L22 - "In view of…." The sentence is unclear, needs to be revised
* P6 L29 - "colonoscope should slipped" - the idea is not clear, needs to be
revised
* P6 L56 - "There is a cohort study collecting" - * Authors need to use the past
tense when referring to previous studies
* P6 L60 - "in lesser content" - needs revision
* P10 L32 - Either cryptococcosis or cryptococcus infection
General comments 
* The reference number should be before the full-stop.
* You cannot do a fistulogram after a fistula heals, it is a contrast enema.
* Date of hip necrosis - I feel it is too specific and may allow the identification
of the patient, better to limit it to the month and year.
* P5 L27 - Histology might be a better term than "pathology"
* P7 L3 - is it a "systematic" review?
ADDITIONAL REQUESTS/SUGGESTIONS:
