To compare the effectiveness of sharp excision of endometriosis with sham surgical excision in alleviating endometriosis-associated pain for up to 1 year following surgery.
                Patients requiring a laparoscopy for severe pelvic pain were eligible. If endometriosis was visually identified at laparoscopy, a biopsy of a representative lesion was taken. The women were then randomized either to have all remaining endometriosis excised with laparoscopic scissors (the excision group) or to have no further surgical treatment (the control group). Patients were asked to complete daily pain scales for 1 month preoperatively and quarterly for 1 year postoperatively. Subjects were blinded to their treatment allocation for 1 year.
                Twenty-nine women underwent laparoscopy and biopsy and were randomized to have excision or no treatment of endometriosis. The excision and control groups were similar in age, parity, and revised American Society for Reproductive Medicine stage of disease. Sixteen women completed the full year of follow-up: 9 in the excision group, and 7 in the control group. Overall, recorded pain was significantly reduced at 1 year (P < 0.05), with no significant difference between the excision and control groups.
                Laparoscopy with diagnostic biopsy alone is associated with a significant reduction in pain for up to 1 year postoperatively. Although the study lacked sufficient statistical power to exclude an effect of excision, pain relief in each group was similar. These results indicate a potential benefit of sham surgical procedures in assessing novel surgical interventions. To examine the effect on pain and quality of life for women with all stages of endometriosis undergoing laparoscopic surgery compared with placebo surgery.
                A randomized, blinded, crossover study.
                A tertiary referral unit in a district general hospital.
                Thirty-nine women with histologically proven endometriosis completed the 12-month study.
                Women were randomized to receive initially either a diagnostic procedure (the delayed surgical group) or full excisional surgery (the immediate surgery group). After 6 months, repeat laparoscopy was performed, with removal of any pathology present.
                The end points were changes from baseline values of visual analogue pain scores, validated quality-of-life instruments (EQ-5D and SF-12), and sexual activity questionnaire scores. Patients and assessors of outcomes were blinded to the treatment-group assignment.
                Significantly more of the 39 women operated on according to protocol reported symptomatic improvement after excisional surgery than after placebo: 16 of 20 (80%) vs. 6 of 19 (32%); chi(2)(1) = 9.3. Other aspects of quality of life were also significantly improved 6 months after excisional surgery but not after placebo. Progression of disease at second surgery was demonstrated for women having only an initial diagnostic procedure in 45% of cases, with disease remaining static in 33% and improving in 22% of cases. Nonresponsiveness to surgery was reported in 20% of cases.
                Laparoscopic excision of endometriosis is more effective than placebo at reducing pain and improving quality of life. Surgery is associated with a 30% placebo response rate that is not dependent on severity of disease. Approximately 20% of women do not report an improvement after surgery for endometriosis. To assess the efficacy of two laparoscopic methods for the management of endometriomas with regard to pain relief, pregnancy rate, and disease recurrence.
                Prospective, randomized clinical trial.
                Tertiary care hospital.
                Sixty-four patients with advanced stages of endometriosis.
                Patients were randomly allocated at the time of laparoscopy to undergo either cystectomy of the endometrioma (group 1) or drainage of the endometrioma and bipolar coagulation of the inner lining (group 2).
                Pain relief and pregnancy rate.
                Thirty-two patients were enrolled in each group. The 24-month cumulative recurrence rates of dysmenorrhea, deep dyspareunia, and nonmenstrual pelvic pain were lower in group 1 than in group 2 (dysmenorrhea: 15.8% versus 52.9%; deep dyspareunia: 20% versus 75%; nonmenstrual pelvic pain: 10% versus 52.9%). The median interval between the operation and the recurrence of moderate to severe pelvic pain was longer in group 1 than in group 2 (19 months [range, 13.5-24 months] versus 9.5 months [range, 3-20 months]). The 24-month cumulative pregnancy rate was higher in group 1 than in group 2 (66.7% versus 23.5%).
                For the treatment of ovarian endometriomas, a better outcome with a similar rate of complications is achieved with laparoscopic cystectomy than with drainage and coagulation. To ascertain whether the frequency of pelvic pain recurrence is reduced and time to symptoms recurrence is prolonged in women with symptomatic endometriosis undergoing conservative surgery and post-operative hormonal therapy compared with women treated with surgery only. Pregnancy rates and time to conception in women wanting children were also evaluated.
                A multicentre, prospective, randomised controlled study.
                Nineteen Italian academic departments and teaching hospitals specialising in reparative and reconstructive surgery.
                A total of 269 women undergoing conservative surgery for mild to severe symptomatic endometriosis.
                After surgery the women were assigned to treatment with subcutaneous goserelin depot injections for six months or to expectant management. Dysmenorrhoea, deep dyspareunia, nonmenstrual pain and general discomfort were graded according to a verbal rating scale from 0 (absent) to 3 (severe) and the scores summed to give a total symptoms score. Only patients with at least one preoperative moderate or severe symptom were enrolled. The women were evaluated regularly for two years.
                Post-operative pain recurrences (total symptoms scores > or = 5), time to recurrence, pregnancy rates and time to conception in the two study groups.
                At one- and two-year follow up visits, 14/107 (13.1%) and 19/81 (23.5%) patients had moderate or severe symptoms recurrence in the goserelin group compared with, respectively, 22/103 (21.4%) and 27/74 (36.5%) in the expectant management group (P = 0.143 at 1 year and 0.082 at 2 years). Time to symptoms recurrence was significantly longer in the goserelin group according to survival analysis (Wilcoxon test, P = 0.041). Among women wanting children, few conceptions occurred in both the goserelin (8/69, 11.6%) and the expectant management group (14/76, 18.4%). There was no significant difference at survival analysis (Wilcoxon test, P = 0.427).
                Post-operative treatment with goserelin significantly prolonged the pain-free interval after conservative surgery for symptomatic endometriosis and did not influence reproductive prognosis. In order to analyse the efficacy of resection/ablation of minimal/mild endometriotic lesions for improving fertility, we conducted a randomized clinical trial. Eligible patients were women aged </=36 years who were trying to conceive and had a laparoscopically confirmed diagnosis of minimal/mild endometriosis (stage I or II of the revised American Fertility Society classification) and otherwise unexplained infertility for >/=2 years. Eligible women were randomly assigned to resection or ablation of visible endometriosis (54 patients) or diagnostic laparoscopy only (47 patients). After laparoscopy women tried to conceive spontaneously for 1 year (follow-up period). A total of five women withdrew from the study: three for personal reasons, and two were lost to follow-up. Considering 51 women in the resection/ablation and 45 in the no-treatment group who ended the follow-up period, 12 (24%) in the resection/ablation group and 13 (29%) in the no treatment group conceived; the difference was not significant. Two spontaneous abortions were observed in the resection/ablation group and three in the no-treatment one. Thus the 1 year birth rate was 10 out of 51 women (19.6%) in the resection/ablation group and 10 out of 45 women (22.2%) in the no-treatment group. In conclusion, the results of this study do not support the hypothesis that ablation of endometriotic lesions markedly improves fertility rates. To determine the difference between two laparoscopic methods for the management of endometriomas with regard to recurrence of signs and symptoms and pregnancy rate.
                Prospective, randomized clinical trial.
                Infertility and gynecologic endoscopy units of two medical university hospitals.
                One hundred patients with endometriomas who had either infertility or pelvic pain.
                Patients were randomly divided into two groups; one group underwent cystectomy (group 1), and fenestration and coagulation were performed for the other (group 2).
                A comparison of recurrence of signs and symptoms of endometriomas and pregnancy rates in two groups.
                Fifty-two patients were studied in group 1 and 48 in group 2. The recurrence of symptoms, such as pelvic pain and dysmenorrhea, was 15.8% in group 1 and 56.7% in group 2 after 2 years. The rate of reoperation was 5.8% in group 1 and 22.9% in group 2 and these differences were statistically significant. The cumulative pregnancy rate was significantly higher in group 1 (59.4%) than in group 2 (23.3%) at 1-year follow-up.
                Laparoscopic cystectomy of endometriomas is a better choice than fenestration and coagulation because the former technique leads to a lower recurrence of signs and symptoms and a lower rate of reoperation and a higher cumulative pregnancy rate than the latter. We sought to evaluate the efficacy of postoperative administration of monophasic, combined, low-dose oral contraceptives on endometrioma recurrence and on persistence-recurrence of associated pain symptoms after laparoscopic treatment of moderate-to-severe endometriosis.
                In a prospective, randomized trial 70 patients who were not attempting to conceive, aged 20 to 35 years, underwent laparoscopic excision of ovarian endometriomas, followed by either postoperative administration of low-dose cyclic oral contraceptives for 6 months or no treatment on the basis of a computer-generated sequence. At 3 and 6 months after surgery and then at 6-month intervals, both groups underwent ultrasonographic examination for possible evidence of endometrioma recurrence and for evaluation of the absence, persistence, or recurrence of pain symptoms.
                Two patients in the oral contraceptive group did not complete the study. After a mean follow-up of 22 months (range, 12-48 months), there were 2 (6.1%) endometrioma recurrences in the 33 patients who received postoperative oral contraceptives versus 1 (2.9%) recurrence in the 35 patients in the control group (not significant). The moderate-to-severe pain recurrence rate was 9.1% in the oral contraceptive group versus 17.1% in the control group (not significant). The mean time to recurrence of either symptoms or endometriomas was 18.2 months in the oral contraceptive group versus 12.7 months in the control group. The 12-month cumulative recurrence rate at life-table analysis was significantly lower for patients receiving oral contraceptives versus control subjects, whereas no significant difference was evident at 24 and 36 months.
                Postoperative administration of low-dose cyclic oral contraceptives does not significantly affect the long-term recurrence rate of endometriosis after surgical treatment. A delay in recurrence is evident at life-table analysis. To compare endometrial laser ablation (ELA) with transcervical resection of the endometrium (TCRE) in the treatment of menorrhagia.
                Randomised controlled trial.
                Gynaecology department of a large teaching hospital.
                Women with menorrhagia due to dysfunctional uterine bleeding (n = 372) were randomly allocated to ELA (n = 188) or TCRE (n = 184).
                Operative complications, post-operative recovery, relief of menstrual and other symptoms, need for further surgical treatment, satisfaction with treatment after 6 and 12 months, and differential resource use.
                TCRE was significantly quicker, with lower rates of fluid overload. Perioperative morbidity was low and similar in both groups. Outcome at 12 months was also similar: 72 women (45%) had either amenorrhoea or brown discharge in the ELA group compared with 71 (49%) in the TCRE group; 79 (49%) versus 68 (46%) had lighter periods. Thirty (16%) versus 36 (20%) had received further surgical treatment: 9 (5%) compared with 25 (14%) had had a hysterectomy and 21 (11%) versus 11 (6%) had received repeat ablation. Anxiety and depression, dysmenorrhoea and pre-menstrual symptoms were improved by both procedures and bladder symptoms were affected by neither. At 12 months 148 (90%) women in the ELA group and 140 (91%) women in the TCRE group were satisfied with their treatment. The estimated additional cost of ELA was Pound 145 per procedure.
                At one year there was no clear difference in clinical outcome between ELA and TCRE. Both procedures were associated with low morbidity. ELA was the more costly procedure. Despite the need for further surgery for about one in six women, satisfaction rates were high following both ELA and TCRE. To evaluate the effectiveness and safety of endometrial laser ablation and transcervical resection of the endometrium compared with hysterectomy in the surgical treatment of women with dysfunctional uterine bleeding.
                Prospective randomised controlled trial.
                Gynaecology department of a large teaching hospital.
                204 women who would otherwise have been undergoing hysterectomy for menorrhagia were recruited between August 1990 and March 1992 and randomly allocated to hysterectomy (n = 99) or conservative (hysteroscopic) surgery (transcervical resection (n = 52) and laser ablation (n = 53)).
                Operative complications, postoperative recovery, relief of menstrual and other symptoms, patient satisfaction with treatment after six and 12 months.
                Women treated by hysteroscopic surgery had less early morbidity and a significantly shorter recovery period than those treated by hysterectomy (median time to full recovery 2-4 weeks v 2-3 months, P < 0.001). Twelve months later 17 women in the hysteroscopy group had had a hysterectomy, 11 for continuing symptoms; 11 women had had a repeat hysteroscopic procedure; 45 were amenorrhoeic or had only a brown discharge; and 35 had light periods. Dysmenorrhoea and premenstrual symptoms improved in most women in both groups. After 12 months 89% (79/89) in the hysterectomy group and 78% (75/96) in the hysteroscopy group were very satisfied with the effect of surgery (P < 0.05); 95% (85/89) and 90% (86/96) thought that there had been an acceptable improvement in symptoms, and 72% (64/89) and 71% (68/96) would recommend the same operation to others.
                Hysteroscopic endometrial ablation was superior to hysterectomy in terms of operative complications and postoperative recovery. Satisfaction after hysterectomy was significantly higher, but between 70% and 90% of the women were satisfied with the outcome of hysteroscopic surgery. Hysteroscopic surgery can be recommended as an alternative to hysterectomy for dysfunctional uterine bleeding.
There is good evidence that excisional surgery for endometriomata provides a more favourable outcome than drainage and ablation with regard to the recurrence of the endometrioma, recurrence of pain symptoms, and subsequent spontaneous pregnancy in women who were previously subfertile. Consequently this approach should be the favoured surgical approach. However in women who may subsequently undergo fertility treatment, insufficient evidence exists to determine the favoured surgical approach.
