Endometrial ablation. Improvement in PMS related to the decrease in bleeding.

Of 108 patients evaluated before and after ablation of the endometrium since July 1986, for menorrhagia and symptoms associated with the menstrual period, 57 met criteria for premenstrual syndrome (PMS). An additional 35 patients had symptoms associated with their menstrual period but did not qualify for a diagnosis of PMS. Following endometrial ablation most patients in both groups reported either amenorrhea or spotting and decreased severity of symptoms. The degree of improvement in both PMS and perimenstrual symptoms seemed to be related to the degree to which bleeding was reduced.
