Manuscript content is now improved thoroughly. Medical English writing can be improved. ------------------------------------------------------------------------------- 
Major Compulsory Revisions (that the author must respond to before a decision on publication can be 
reached) 
------------------------------------------------------------------------------- 
Minor Essential Revisions (such as missing labels on figures, or the wrong use of a term, which the author 
can be trusted to correct) 
The authors state in their conclusion that further efforts to reduce surgical trauma in open biliary surgery are 
motivated, suggesting that only the surgical approach is responsible for the mortality. Although other 
variables too have been mentioned in the text, they should clearly include the importance of patient 
selection and potential bias in their conclusion. If only 'inpatient' cholecystectomies were included, data concercerning 'outpatient' procedures should be excluded. I assume the word 'inpatient' may be omitted throughout the text.

Discretionary Revisions (which the author can choose to ignore) 
 Unable to decide on acceptance or rejection until the authors have responded to the major What next?:
