Sandberg EM, et al. - The influence of concomitant endometriosis on surgical outcomes of laparoscopic hysterectomy (LH) was analyzed. Researchers also assessed if it should be considered as case-mix variable. The findings here provided numeric support for the influence of concomitant endometriosis on surgical outcomes of LH, without bowel or bladder dissection. Only stages III and IV were observed to be linked with a longer operative time and more blood loss. They thus recommended considering these (stages III and IV) as case-mix variables in future quality measurement tools.
