Ovary Stuck To The Bowel And Endometriosis After Hysterectomy That Is Painful

hi im 45 years old, i have had a hysterectomy 7 years ago for fiborids and had a cyst drained form my right ovary last year. I have emdermitoris and now my ovary is stuck to my bowel, very painful. my dr says loose weight and he will do surgery. he said he is not sure if it will be open or lap. why would it be have to be open? worried. Had a fiborids removed by open surgery a year before hyst. so know the pain of that.

thanks verona
