 A paper of limited interest Level of interest: 
 Other (see below) Advice on publication: 
1) You have to provide the pictures of lower abdominal CT in figures, because you could show two 
interesting findings in this case, bilateral ovarian chocolate cysts and "eccentric wall thickening of the 
sigmoid", which are thought to be important for diagnosis of endometriosis. 
2) Because the choice of treatment method is so important matter, authors have to give more 
particular account of the reason you have chosen GnRHa analogue for treatment of endometriosis in 
this case compared with other treatment methods, danazol therapy, surgical therapy (colorectomy 
etc.) and so on.
