Feasibility and safety of laparoscopic approach in obese patients with endometriosis: a multivariable regression analysis

Body mass index and the diagnosis of endometriosis: Findings from a national data linkage cohort study

BACKGROUND

Women with lower body mass index (BMI) have a higher risk of surgically confirmed endometriosis but this finding runs counterintuitive to the oestrogen-dependent theory for the disease. Increasingly, endometriosis is diagnosed via non-surgical methods. We examined BMI at age 18-23 years, and changes in BMI, and the risk of endometriosis according to the diagnostic method.

METHODS

We analysed data from 11 794 young women, born in 1989-95, who completed six surveys as part of an Australian, longitudinal cohort study between 2013 and 2018. Women's survey responses were linked to administrative health records to identify endometriosis. Cox proportional hazards models modelled associations between BMI at age 18-23 years, and changes in BMI, and endometriosis. Analyses were stratified by the diagnostic method of endometriosis: clinically confirmed endometriosis (based on hospital discharge diagnosis) versus clinically suspected endometriosis (women's reports of physician-diagnosed endometriosis).

RESULTS

There were 223 cases of clinically confirmed endometriosis and 396 cases of clinically suspected endometriosis. Women who gained weight after age 18-23 had lower risk of clinically confirmed endometriosis than women without endometriosis whose weight remained stable (HR = 0.64, 95% CI = 0.47-0.88). Women who were overweight (HR = 1.29, 95% CI = 1.01-1.66) at age 18-23 had higher risk of clinically suspected endometriosis than women of normal weight without endometriosis.

CONCLUSIONS

The risk of clinically confirmed endometriosis was lower among women who gained weight compared to women with stable weight. The risk of clinically suspected endometriosis was higher among women who were overweight compared to normal weight.

Burden of Endometriosis: Infertility, Comorbidities, and Healthcare Resource Utilization

The goal of our study was to evaluate the burden of endometriosis in the community by comparing healthcare resource utilization, total direct medical costs, infertility, and comorbidity rates of women with and without a diagnosis of endometriosis. A retrospective case–control study was performed using the databases of a 2.1 million-member nationwide healthcare plan. The study population included women aged 15–55 years enrolled in the healthcare plan. Women with a diagnosis (ICD-9) of endometriosis were compared to controls without diagnosed endometriosis. Women were individually matched (1:4) on age and residence area. Patient characteristics were described, including infertility, comorbidities, and annual healthcare resource utilization. Total direct medical costs were analyzed in a generalized linear model adjusting for age. Women with endometriosis (n = 6146, mean age ± SD: 40.4 ± 8.0 y) were significantly more likely than controls (n = 24,572) to have a lower BMI and a higher socioeconomic status. After adjusting for BMI and socioeconomic status, endometriosis was significantly associated with infertility (OR = 3.3; 95% CI 3.1–3.5), chronic comorbidities, higher utilization of healthcare services (hospitalization: OR = 2.3; 95% CI 2.1–2.5), pain medications, and antidepressants. Women aged 15–19 y with endometriosis had substantially higher utilization of primary care visits (57.7% vs. 14.4%) and oral contraceptive use (76.9% vs. 9.6%). Direct medical costs associated with endometriosis were higher than those for controls (OR = 1.75; 95% CI 1.69–1.85). Endometriosis is associated with a high burden of comorbidities, increased healthcare resource utilization, and excess costs, particularly for younger patients whose healthcare needs may differ widely from the older population.

Evolution of bowel complaints after laparoscopy endometriosis surgery: a 1497 women comparative study

STUDY OBJECTIVE

To assess what degree can digestive symptoms improve after endometriosis surgery for different localisations?

DESIGN

A comparative retrospective study employing data prospectively recorded in The North-West Inter-Regional Female Cohort for Patients with Endometriosis (CIRENDO) from June 2009 to November 2018.

SETTING

Two referral centres Patients: 1,497 women undergoing surgery due to pelvic endometriosis were divided into three groups: superficial endometriosis (Group 1, n=396), deep endometriosis sparing the bowel (Group 2, n=337), and deep endometriosis involving the bowel (Group 3, n=764).

INTERVENTIONS

Surgery for endometriosis.

MEASUREMENTS AND MAIN RESULTS

Preoperative and postoperative gastrointestinal symptoms were evaluated with standardised questionnaires, including the Gastrointestinal Quality of Life Index (GIQLI) and Knowles-Eccersley-Scott-Symptom questionnaire (KESS). The degree of postoperative improvement in digestive symptoms was compared between the groups. The women in Group 3 were significantly symptomatic in terms of cycle-related gastrointestinal symptoms and scores of standardised questionnaires GIQLI, KESS. According to the 1-year postoperative evaluation, women in Group 3 experienced the most significant improvement in their gastrointestinal symptoms.

CONCLUSION

Women with severe bowel symptoms and deep endometriosis infiltrating the bowel should be informed about the high probability of symptom improvement after the removal of bowel nodules. Conversely, in women without deep endometriosis, postoperatively, there is less improvement in baseline digestive complaints.
