Effectiveness of laparoscopic treatment for deep infiltrating type endometriosis

Objective To analyze the effect of laparoscopic excision on deep infiltrating type endometriosis(DIE) in posterior pelvis.Methods Data of 35 cases of posterior pelvic DIE admitted to General Hospital of PLA from Jan.2006 to Jan.2009 were retrospectively analyzed.All the cases were pathologically confirmed and treated with laparoscopic surgery.10-point linear visual analog scale(VAS) was used to estimate the degree of pre-and post-operative pain.Results Thirty-four patients were treated successfully by laparoscopic surgery,in one case it was shifted to open laparotomy because of malignant transformation of endometriosis.No complication occurred.There was an obvious decline of VAS score for dysmenorrhoea after operation compared with that before operation(5.8±1.7 vs 1.2±1.3,P < 0.001).Thirteen cases with dysmenorrhoea(39.3%) showed significant improvement of symptoms,and satisfactory improvement was found in 20 cases(60.7%).Conclusion Laparoscopic excision for posterior type of DIE is effective and safe,it can ameliorate dysmenorrhoea and improve patient’s quality of life.
