Nowadays, an increasing number of minimal invasive treatment alternatives to hysterectomy may be offered to the patient. In determining the appropriate treatment option, the patient has a distinct dilemma if a minimal invasive treatment with lesser effect than hysterectomy should be chosen or if a hysterectomy should be chosen which is a major surgery and requires longer recovery than the minimal invasive alternative. Quality-of-life (QoL) questionnaires that take subjective health perception into account are currently used to assess the treatment effects. The objective of this literature study is to determine and discuss the role of QoL as an outcome in randomized controlled trials (RCT) or systematic reviews of RCTs that study the treatment effect of hysterectomy compared to that of minimal invasive alternatives. A systematic literature search was performed in the PubMed database and in the Cochrane database to find randomized trials and systematic reviews of randomized trials, comparing hysterectomy with minimal invasive or conservative treatment options with sufficient follow-up using satisfaction, health status, and quality of life as outcomes. The results were based on nine randomized trials and two systematic reviews. The differences are mostly in favor of hysterectomy. In two out of four studied treatment alternatives, the satisfaction or health status is different in favor of hysterectomy while the QoL is equivalent. After 2 years of follow-up, differences between both groups have disappeared, possibly because of the crossover effect. Possible reasons for the lesser response of QoL compared to satisfaction or health status are discussed. The fundamental question if patients have a better quality of life at all times if they choose for a minimal invasive alternative of hysterectomy remains unresolved. Information, individualization, and freedom of choice before surgery probably best serve the sense of well being and quality of life thereafter.
Despite an increasing number of alternative minimal invasive treatment options, the hysterectomy in the Netherlands is still frequently performed in premenopausal patients with uterine symptoms. According to a Dutch hospital-based database (Prismant), approximately 16,000 hysterectomies are performed each year. Alternative treatment options are medical treatment, including the levonorgestrel-delivering intrauterine system (LNG-IUS), endometrial ablation, embolization or occlusion of uterine vessels, and the partial removal of uterine structures such as polyps, fibroids, and the uterine corpus (subtotal hysterectomy).
The dilemma for patients and doctors in the choice between hysterectomy and minimal invasive or conservative treatment is the tradeoff between a faster recovery in minimal invasive surgery and the possibly lesser effect of the treatment.
There have been different ways in evaluating treatment, such as satisfaction and health status (e.g., symptom score). In 1952, WHO reformulated the definition of health being “not only the absence of disease or infirmity, but also the presence of physical, mental and social wellbeing,” hereby introducing a subjective element in the definition of health . The—subjective—perception of health determines the quality of life (QoL). Instead of using outcomes such as satisfaction of treatment or health status, the treatment effect is increasingly measured as QoL. QoL is measured ideally by questionnaires that have been validated to be reliable, reproducible, and specific . In generic QoL questionnaires, the general health is inquired, while in disease-specific QoL, the questions apply more to specific medical situations. The latter questionnaires are more appropriate to assess treatment effects. QoL should be distinguished from health status (e.g., menstrual score) or satisfaction after treatment, which are considered causal items where the QoL is based upon. Although QoL seems an appropriate outcome to compare conventional and minimal invasive treatment, the results sometimes differ from the health status or the level of satisfaction. It is therefore a matter of debate on what results patients should be counseled.
The objective of this literature study is to determine and discuss the role of QoL as an outcome in randomized controlled trials (RCT) or systematic reviews of RCTs that study the treatment effect of hysterectomy compared to that of minimal invasive alternatives.
A systematic literature search was performed in the PubMed database and in the Cochrane database to find systematic reviews of randomized trials, comparing hysterectomy with minimal invasive or conservative treatment options [medical treatment including LNG-IUS, endometrial ablation, and uterine artery embolization (UAE) or ligation] with sufficient follow-up using satisfaction, health status, and quality of life as outcomes. If no systematic reviews or later published data were available, then randomized trials were also included. The search terms (“menorrhagia” [Mesh] OR “leiomyoma” [Mesh] AND “Quality of Life” [Mesh] AND “Hysterectomy” [Mesh]) limited to randomized trials or reviews were used in the PubMed database as well as in the Cochrane database.
From the PubMed database, 26 articles meeting the search terms were found, of which two were Cochrane systematic reviews [3, 4]. There were four randomized trials detected that met the criteria [5–8]. Two articles on first-generation endometrial ablation [9, 10] met the criteria but were appropriately reported in the identified systematic review. Checking cross references from this review, four more randomized trials were identified [11–14]. From the Cochrane database using the Mesh terms “hysterectomy” and “Quality of life,” two hits with regard to systematic reviews were retrieved and 43 trials. The two systematic reviews were already found in the PubMed database. Three more potentially suitable trials were found but were excluded [15–17]. In one study that compared uterine artery ligation with hysterectomy, only the design was described . Follow-up lacked in another study , and quality of life was not used as an outcome in the third excluded study . With the mesh term “uterine artery embolization,” one more Cochrane review was detected . However, this review addressed short-term results, and no follow-up was reported, while later published articles reported follow-up data on uterine artery embolization [6, 7]. The process of selection was done by two authors (JH, HB) independently. No cases of disagreement occurred.
On four minimal invasive or conservative therapies, we found systematic reviews or RCTs comparing them with hysterectomy. These alternative treatment options were hormonal medication [4, 5], LNG-IUS (Mirena) [4, 8], first-generation endometrial ablation [3, 10], and UAE [6, 7]. On the other minimal invasive treatment options (myomectomy, occlusion of the uterine artery), no randomized trials could be found in the aforementioned databases and the international trial register (http://clinicaltrials.gov/ct2/search/browse?brwse=cond_cat_BXS).

In the Cochrane review of Marjoribanks et al. , studies were systematically collected that compared medical treatment with surgery, including hysterectomy in premenopausal women with heavy menstrual bleeding. Eight studies met the inclusion criteria. The authors randomized a total of 821 women, 411 receiving surgery and 410 receiving medical treatment.
The authors conclude in the abstract: “surgery, especially hysterectomy, reduces menstrual bleeding at one year more than medical treatments but LNG-IUS appears equally effective in improving quality of life. The evidence for longer term comparisons is weak and inconsistent. Oral medication suits a minority of women long term.”
We will address the comparison of hysterectomy and LNG-IUS separately in the next section.

Effect size (95%CI)
Although many quality-of-life scales reported no differences between surgery groups, there was some evidence of a greater improvement in general health for hysterectomy patients after 1 and 2 years, when compared to those who had endometrial destruction. This was also the case after 2 years of follow-up in the SF-36 domains social functioning and pain. After 4 years, this difference between groups had narrowed and was just outside the 0.05 level of significance.
Reintervention rate in patients treated by ablation ranged from 14% after 1 year to 38% (only hysterectomies) after 4 years.
The authors conclude that “endometrial destruction is an alternative to hysterectomy that should be offered to women with heavy menstrual bleeding. There are high satisfaction rates, shorter operation time and hospital stay, earlier recovery and reduced post-operative complications.” They stress however that the patient should be informed about the higher risk of reoperation after endometrial destruction.

In two randomized trials, the UAE is compared to hysterectomy in terms of satisfaction and quality of life. In the EMMY trial , more than 90% of patients in both groups were at least moderately satisfied after a follow-up of two years, but a larger proportion of the patients in the hysterectomy group was satisfied to very satisfied (45/75 = 60%) compared with the UAE group (34/81 = 42%; p = 0.026). However, the primary outcome, the quality of life measured by generic (SF36 and EQ5) as well as health-related questionnaires, did not differ after 2 years. The “crossover” to hysterectomy in the UAE group was 25%. In the conclusion of the abstract, it is stated that “on the basis of HRQOL results, the authors determined that UAE is a good alternative to hysterectomy.” In the second study of Edwards et al. , patients undergoing UAE (n = 106) were compared to patients undergoing surgery (43 hysterectomies and eight myomectomies). After 1 year of follow-up, no differences of the eight components of the SF-36 scores were found between both groups, while the symptom scores were better in the surgical group (p = 0.03). In the UAE group, 21 patients (20%) required within 1 year a reintervention, such as hysterectomy or repeated embolization for inadequate symptom control. The authors conclude in the abstract that “In women with symptomatic fibroids, the faster recovery after embolization must be weighed against the need for further treatment in a minority of patients.”
While in the past the hysterectomy was the treatment of choice in case of benign gynecological disorders, nowadays, many alternative treatment options are available that are less invasive and preserve the uterus. In the office, the challenge is to support patients in their dilemma of choosing hysterectomy with adequate symptom relief or minimal invasive treatment with a risk of lesser symptom control.

How can it be explained that this response of treatment satisfaction is better than the response of QoL and what consequence may it have for our recommendations to the patient? Two suppositions may explain that quality of life is less or not at all responsive after treatment. First, we can assume that there is a difference in quality of life which is not detected. The second explanation is that, despite differences in symptom control between treatment arms, the patients experience indeed no differences in quality of life.
Let us first elaborate on the possibility that there is a difference in quality of life between hysterectomy and the minimal invasive alternative which is not detected. In all studies that report a difference in QoL that is not statistically significant, this difference is in favor of the hysterectomy. Therefore, insufficient power may play a role, although in other studies with comparable numbers comparing gynecological surgery, significant treatment effects have been demonstrated by QoL questionnaires (SF-36) .
In all trials, generic QoL questionnaires were used, such as the SF-36, the Euroqol five (EQ5) dimensions, and the Nottingham health profile. It is well established that disease-specific questionnaires are more responsive to treatment effects than generic questionnaires that are designed to measure health-related quality of life across a wide variety of diseases . Nowadays, validated instruments are available that measure QoL in benign gynecological disease, such as the uterine fibroid symptom list designed by Spies et al. . Also, for menorrhagia, various lists are reported in the literature . It is recommended for optimal sensitivity and responsiveness in clinical trials to use a combination of a generic and a disease-specific questionnaire .
The second possibility is that there is no difference in QoL between groups indeed despite a significantly differing symptom control between treatment arms. This could be explained by the fact that patients undergoing a minimal invasive treatment take a lesser effect into account. Consequently, they are not unhappy in all cases if the treatment has failed. It is well known from preference trials that the majority of women are willing to accept a failure rate of the minimal invasive option up to 50% in escaping a hysterectomy .
In the reported studies, a large proportion of patients randomized to the minimal invasive alternative treatment eventually “crossed over” to hysterectomy (25–53%). Intention-to-treat analysis may equalize effects and explain the disappearance of the differences over time. This accounts for quality of life and to a lesser extent for health status (satisfaction) as the difference in health status is larger from the start. In the study of Hehenkamp et al. , after 2 years of follow-up, satisfaction differed significantly between treatment arms (UAE and hysterectomy) while no time effect and treatment effect of the quality of life were reported.
In conclusion, the fundamental question if patients have a better quality of life at all times if they choose for a minimal invasive alternative of hysterectomy remains unresolved. Some do and some do not. As quality of life depends on the extent to which patients’ expectations are matched by reality , adequate information beforehand on the surgical options, tailored to the particular situation of the patient, is of utmost importance. In this way, the individual preference of the patient can be best explored. If the patient is well prepared on certain risk of treatment failure, the eventual period of complaints and concerns to come to a decision of an often more invasive reintervention is better coped with and may not be reflected in the QoL. The QoL of patients crossing over has been reported significantly worse than in the group of patients that comply with their original treatment .
Information, individualization, and freedom of choice before surgery probably best serve the sense of well being and quality of life thereafter.
