Laparoscopic treatment of pelvic pain associated with minimal and mild endometriosis with use of the Helica Thermal Coagulator

The Surgical Benefit of Hysterolaparoscopy in Endometriosis-Related Infertility: A Single Centre Retrospective Study with a Minimum 2-Year Follow-Up

AIM

This study examined the fertility performance of women after combined hysterolaparoscopic surgical management of endometriosis. Design: This study is a hospital-based retrospective review.

MATERIALS AND METHODS

Data collected from the records of all patients presented with endometriosis-related infertility using a checklist designed for the purpose. Result: A total of 81.3% (370/455) of women who have had the desire to have children became pregnant during the study period after the surgery. Of those who became pregnant, all three-hundred-forty-seven patients were followed to the end of their pregnancies. A successful live birth occurred in 94.2% (327/347) of individuals, and pregnancy loss occurred in 5.8% (20/347). The mean patient age was 34.1 ± 4.1 years, and the average duration of infertility was 3.4 ± 3.3 years. Pregnancy occurred spontaneously in 39.5% (146/370) of patients, after artificial insemination (AIH) in 3.8% (14/370) of women, and after in vitro fertilization-embryo transfer (IVF-ET) in 56.8% (210/370) of cases. Patients aged ≤ 35 years had a higher chance of conception post-surgery-84% versus 77%, respectively (p = 0.039). Based on the modes of pregnancy, the timely introduction of an assisted reproductive technique (ART) demonstrated a significant effect on fertility performance postsurgery. Comparatively, this effect was 91.3% vs. 74.1% among the ≤35- and >35-year-old age groups, respectively. There was no significant difference in reproductive performance based on stages of endometriosis, nor in the other parameters evaluated. Conclusion: Our data are consistent with previous clinical studies regarding the management options of endometriosis-related infertility. Overall, the combined hysterolaparoscopy treatment is a very effective and reliable procedure, and is even more effective when combined with ART. It enhances women's wellbeing and quality of life, and significantly improves reproductive performance.

Surgical Outcomes in Patients With Endometriosis: A Systematic Review

OBJECTIVE

Among women treated surgically for endometriosis-associated pain, comprehensive data are lacking on the proportions of patients who experience little or no symptom relief, develop recurrent symptoms, or require further surgical treatment for endometriosis. The aim of this study was to assess the efficacy of surgical procedures used to treat endometriosis-associated pain.

METHODS

Medline and Embase were searched on October 13, 2016. Articles referring to women undergoing surgery for the treatment of endometriosis-associated pain were screened by two independent investigators. For each included treatment arm, data were extracted for the proportion of patients reporting partial or no improvement after surgery for endometriosis-associated pain, pain recurrence, or requirement for further surgery.

RESULTS

A total of 38 studies were included. Most studies did not report relevant outcomes to evaluate pain (71.1%) and recurrent surgery (68.4%). Of the women who underwent lesion excision, 11.8% reported no improvement in pain, and 22.6% underwent further surgery. Postoperative pain, recurrent pain, and adverse events were reported by 34.3%, 28.7%, and 14.8%, respectively, of patients who underwent excision or ablation of endometriosis combined with pelvic denervation and in 25.0%, 15.8%, and 8.1% of women who underwent lesion excision alone. Of the patients who were treated surgically for deep endometriosis affecting the bowel and/or bladder, 7.0% experienced recurrent symptoms, and 4.1% underwent further surgery.

CONCLUSION

This review supports the findings of previous studies and highlights the need for standardized reporting and more detailed follow-up after surgery for endometriosis-associated pain.

Systematic review of endometriosis pain assessment: how to choose a scale?

BACKGROUND

Numerous studies concerning endometriosis and pain have been reported. However, there is no consensus on the best method to evaluate pain in endometriosis and many scales have been used. Moreover, there are only a few descriptions of minimal clinically important differences after treatment (MCID) to evaluate variations in pain. In our study, we aim to identify pain scales used in endometriosis pain treatment, to address their strong and weak points and to define which would be the ideal scale to help clinicians and researchers to evaluate endometriosis-related pain.

METHODS

A search of the MEDLINE and EMBASE databases was carried out for publications in English, French or Portuguese from 1980 to December 2012, for the words: endometriosis, treatment, pain. Studies were selected if they studied an endometriosis treatment and a pain scale was specified. A quantitative and a qualitative analysis of each scale was performed to define strong and weak points of each scale (systematic registration number: CRD42013005336).

RESULTS

A total of 736 publications were identified. After excluding duplications and applying inclusion criteria 258 studies remained. We found that the visual analog scale (VAS) is the most frequently used scale. Both VAS and the numerical rating scale (NRS) show a good balance between strong and weak points in comparison with others such as the Biberoglu and Behrman scale. Concerning MCID, only VAS, NRS and Brief Pain Inventory scales have reported MCID and, among these, only VAS MCID has been studied in endometriosis patients (VAS MCID = 10 mm). Adding the Clinical Global Impression score (CGI) to the pain scale allows calculation of the MCID.

CONCLUSIONS

When using pain scales their strengths and weaknesses must be known and included in the analysis. VAS is the most frequently used pain scale and, together with NRS, seems the best adapted for endometriosis pain measurement. The use of VAS or NRS for each type of typical pain related to endometriosis (dysmenorrhea, deep dyspareunia and non-menstrual chronic pelvic pain), combined with the CGI and a quality-of-life scale will provide both clinicians and researchers with tools to evaluate treatment response.

Deep dyspareunia and sex life after laparoscopic excision of endometriosis

BACKGROUND

Among subjects with endometriosis and deep dyspareunia (DD), those with endometriosis of the uterosacral ligament (USLE) have the most severe impairment of sexual function. This study examines the effect of laparoscopic excision of endometriosis on DD and quality of sex life.

METHODS

This observational cohort prospective study included 68 women with endometriosis suffering DD (intensity of pain >or= 6 on a 10-cm visual analogue scale). Patients underwent laparoscopic full excision of endometriosis. Following surgery, they were asked to use nonhormonal contraception devices. Before surgery, at 6- and at 12-month follow-up, patients answered a self-administered questionnaire based on the Sexual Satisfaction Subscale of the Derogatis Sexual Functioning Inventory.

RESULTS

At 6- and 12-month follow-up, women with and without USLE had significant improvement in DD. Subjects with USLE reported increased variety in sex life, increased frequency of intercourse, more satisfying orgasms with sex, relaxing more easily during sex and being more relaxed and fulfilled after sex. Similar improvements were observed among women without USLE; however, for some variables statistical significance was not reached.

CONCLUSIONS

Surgical excision of endometriosis improves not only DD but also the quality of sex life.

Over one thousand patients with early stage endometriosis treated with the Helica Thermal Coagulator (HELICA): safety aspects

STUDY OBJECTIVE

To assess the safety of the Helica Thermal Coagulator in the laparoscopic treatment of early stage endometriosis.

DESIGN

Retrospective, observational.

SETTINGS

The Princess Royal University Hospital, The Sloane and Chelsfield Park Hospitals, Kent, UK.

PATIENTS

One thousand and sixty patients with early stage endometriosis.

RESULTS

All patients were treated laparoscopically with the Helica Thermal Coagulator; a new laparoscopic device that combines electrical energy with helium for the treatment of endometriosis. No major bladder, ureteric or bowel injuries occurred. The only complication was a perforated vagina from the cutting probe during dissection of the cul-de-sac in a patient with a vaginal endometriotic nodule.

CONCLUSION

The Helica Thermal Coagulator is a safe device for the laparoscopic treatment of endometriosis.

Reproductive outcome after laparoscopic treatment of minimal and mild endometriosis using Helica Thermal Coagulator

OBJECTIVE

To investigate the reproductive outcome following Helica Thermal Coagulator (Helica TC) in an infertile population with early-stage endometriosis.

DESIGN

A clinical observational trial conducted in a NHS tertiary referral centre for treatment of endometriosis. Forty-four healthy infertile women (mean age 21 years, range 18-34 years) with laparoscopically confirmed diagnosis of minimal (stage I) or mild (stage II) endometriosis were included. All visible endometriotic lesions and adhesions were treated using Helica TC at the same time of diagnostic laparoscopy. Following laparoscopy, women attempted to conceive spontaneously and were followed for 12 months or until delivery. No hormonal therapy for endometriosis was given whatsoever.

RESULTS

One woman was lost to follow-up and the remaining 43 women were considered in the final analysis. The cumulative pregnancy rate was 23.2% (10/43). All pregnancies occurred spontaneously and neither miscarriages nor ectopic pregnancies were observed. Pregnancy rate did not differ between women with stage I and those with stage II endometriosis. The time-to-pregnancy was similar in women with different stage endometriosis. No surgical complications were encountered.

CONCLUSIONS

These findings suggest that Helica TC is a simple and safe conservative laparoscopic surgery for early-stage endometriosis. Helica TC appears to improve reproductive outcome in women with otherwise unexplained infertility. Large RCTs are needed to define these preliminary data.
