Title: Clinical benefit of oral lactulose for postoperative care of pateints with complicated appendicitis
using propensity score matching analysis
Version: 0 Date: 25 May 2019
Reviewer: Luigi Brusciano
Reviewer's report:
The Authors presented an interesting analysis about clinical benefit of oral lactulose for postoperative
care  of  pateints  with  complicated  appendicitis.  It  is  a  debated  topic  that  needs  consideration  in
Literature. The article is well written and conducted. The reference are updated and the statistics are
readable. 
As minor revisions:
in  the  discussion  section  I  suggest  to  better  analyze  the  role  of  reabilitation  treatment  and  the
importance of controlled diet to prompt the canalization. Therefore the Authors should consider the
following papers:
