Abstract
Background : Endometriosis is a chronic inflammatory disease with a substan-
tial impact on quality of life (QoL) and reproductive health. In sub -Saharan
Africa, delayed diagnosis and limited access to specialized care often result in
advanced disease at the time of surgery. This study aimed to describe the sur-
gical characteristics and assess postoperative quality -of-life outcomes among
women operated for endometriosis in two referral hospitals in Yaoundé, Cam-
eroon. Methods: We conducted a retrospective descriptive and analytical study
involving women surgically treated for endometriosis between January 2018
and December 2023 at the Yaoundé Gyneco-
Obstetric and Pediatric Hospital.
Medical records of patients who underwent surgery for endometriosis were
retrospectively reviewed. Sociodemo graphic, clinical, imaging, surgical, and
postoperative data were extracted from 50 medical records. Pain intensity was
assessed using the Visual Analog Scale (VAS), and quality of life was evaluated
using the Endometriosis Health Profile -5 (EHP-5) questionnaire before and
after surgery. Results: The mean age was 31.1 ± 5.5 years. The most common
phenotypes were superficial endometriosis (68%). Advanced disease predom-

inated, with a mean endometrioma diameter of 94.1 mm and a 36.4% preva-
lence of “kissing ovaries.” Deep infiltrating endometriosis (DIE) was identified
in 38% of cases, including rare diaphragmatic and hepatic involvement. Mod-
erate to severe disease (rASRM stages III -IV) was present in 70.3% of staged
cases. Laparoscopy was the primary surgical approac h (88%). A significant
postoperative reduction in pain was observed, with the mean VAS score de-
creasing from 9.5 ± 1.1 to 3.7 ± 2.7 (p < 0.001). The EHP-5 score significantly
improved from 698.8 ± 171.0 to 350.6 ± 219.5 (p < 0.001). Surgical complica-
tions were infrequent (6%). Postoperative conception occurred in 3 of 14
(21.4%) patients followed for infertility.

1. Introduction
Endometriosis, defined by the presence of endometrial -like tissue outside the
uterine cavity, is a chronic inflammatory condition affecting an estimated 10% of
women of reproductive age globally [1]. It is a leading cause of chronic pelvic pain,
dysmenorrhea, dyspareunia, and infertility, imposing a substantial burden on
physical health, mental well -being, socioeconomic productivity, and diminished
quality of life [2] [3].
In high-income countries, increased awareness and access to advanced imaging
and laparoscopy have improved early diagnosis and management. For decades, a
persistent medical myth suggested that endometriosis was rare among women of
African descent. Recent evidence has decisively debunked this, revealing that Af-
rican women often suffer from more aggressive, late-stage phenotypes due to sys-
temic diagnostic delays [4]. However, endometriosis remains underdiagnosed and
often misinterpreted as a functional or psychosomatic condition. Cultural nor-
malization of menstrual pain, limited specialist availability, and financial barriers
contribute to diagnostic delays, resultin g in more extensive disease at the time of
surgery [5].
The management of endometriosis is multimodal, encompassing medical ther-
apy, surgery, and often, assisted reproductive technologies. Surgery, particularly
laparoscopic excision, plays a pivotal role in providing a definitive diagnosis, re-
lieving pain, improving fertility in specific cases, and treating associated compli-
cations [6] [7]. The primary goals of surgical intervention are the complete re-

moval of all visible endometriotic lesions, restoration of normal pelvic anatomy
through adhesiolysis, and symptom alleviation.
Despite its global prevalence, the clinical profile and surgical outcomes of en-
dometriosis in Sub-Saharan Africa (SSA) remain poorly characterized. Diagnostic
delays are common due to limited access to advanced imaging (e.g., magnetic res-
onance imaging) and specialized gynecological care, often leading to presentation
at advanced disease stages [8] [9]. Furthermore, the availability and outcomes of
laparoscopic surgery, the gold standard for endometriosis management, are not
well-documented in many African contexts.
In Cameroon, as in many SSA countries, there is a critical gap in data regarding
the patient -reported outcomes following intervention. Understanding the local
epidemiological and clinical landscape is essential for developing context -appro-
priate guidelines and advocating for the necessary resources.
Quality of life is now recognized as a key outcome measure in endometriosis
management, alongside traditional surgical and fertility endpoints. Validated in-
struments such as the Endometriosis Health Profile (EHP -5) allow standardized
assessment of patient-centered outcomes [10].
This study aimed to bridge this knowledge gap by describing the surgical as-
pects and evaluating the impact on quality of life and pain in women who under-
went surgery for endometriosis in two hospitals in Yaoundé, Cameroon. We
sought to provide evidence on the feasibility and effectiveness of surgical manage-
ment within our resource-constrained setting.
2. Methods
2.1. Study Design and Setting
This was a hospital -based, descriptive cross -sectional and analytical study with
retrospective data collection on clinical/surgical profiles and prospective assess-
ment of postoperative outcomes. The study was conducted at two facilities: the
Yaoundé Gynaeco-Obstetric and Pediatric Hospital (HGOPY), a public tertiary
referral center, and the Afrique Futur Deo Gracias Hospital in Emana, a private
institution. Both centers offer specialized gynecological surgical services in Ya-
oundé.
2.2. Study Population
Between July 2018 and July 2023, we included all women aged 18 years and above
who underwent surgical intervention (laparoscopy or laparotomy) with a histo-
logically or surgically confirmed endometriosis, with a complete operative report,
and available pre- and postoperative clinical data. Patients with incomplete med-
ical records or those who underwent surgery for other primary indications with
an incidental finding of endometriosis were excluded.
2.3. Data Collection
Data were collected in two phases:
I. Tompeen et al.
DOI: 10.4236/ojog.2026.161019 161 Open Journal of Obstetrics and Gynecology
1) Retrospective Phase: A structured data extraction sheet was used to collect
information from medical records, including sociodemographic characteristics
(age, parity, occupation, education), clinical history (symptoms, duration, infer-
tility status), preoperative investigations (ultrasound, CA -125, MRI), intraopera-
tive findings (phenotypes: superficial, ovarian endometrioma, deep infiltrating
endometriosis; location; the revised American Society for Reproductive Medicine
(rASRM) stage), surgical details ( approach, procedures performed), and periop-
erative complications.
2) Prospective Phase: Eligible patients were contacted by telephone. After ob-
taining informed consent, they were interviewed using two validated tools: the
Visual Analogue Scale (VAS) to assess current pelvic pain intensity (0 = no pain,
10 = worst imaginable pain) and the Endometriosis Health Profile -5 (EHP -5)
questionnaire to evaluate health -related quality of life. The EHP -5 scores [10]
range from 0 (best health) to 100 (worst health) per domain; a higher score indi-
cates poorer QoL. Preoperative EHP-5 scores were not available in archived med-
ical records and were therefore assessed retrospectively during the postoperative
telephone interview. Patients were asked to recall their preoperative health status
using the EHP-5 questionnaire, referring specifically to their condition immedi-
ately prior to surgery. Patients were also asked about postoperative conception.
2.4. Operational Definitions
Superficial Endometriosis: Peritoneal implants without significant infiltration.
Ovarian Endometrioma: Ovarian cyst with typical “chocolate” fluid content.
Deep Infiltrating Endometriosis (DIE): Endometriotic lesions infiltrating the
retroperitoneal space or the wall of pelvic organs to a depth of ≥5 mm (e.g., utero-
sacral ligaments, rectovaginal septum).
rASRM Stage: Disease severity classified according to the revised American So-
ciety for Reproductive Medicine classification [11].
2.5. Ethical Considerations
The study protocol was approved by the Institutional Ethics Committees of both
participating hospitals. For the retrospective component, a waiver for individual
informed consent was granted for the analysis of anonymized archived data. For
the prospective telephone interview, verbal informed consent was obtained from
all participants at the beginning of the call. All data were anonymized and kept
confidential.
2.6. Statistical Analysis
Data were entered and analyzed using IBM SPSS Statistics version 26.0. Descrip-
tive statistics were computed. Categorical variables were expressed as frequencies
and percentages (%). Continuous variables were expressed as mean ± standard
deviation (SD) or m edian with interquartile range (IQR) as appropriate. The
paired samples t-test or Wilcoxon signed-rank test was used to compare preoper-

ative and postoperative VAS and EHP-5 scores, as appropriate. A p-value of <0.05
was considered statistically significant.
3. Results
3.1. Flow of Participants and Sociodemographic Characteristics
A total of 92 patients were identified as having undergone surgery for endometri-
osis. After applying exclusion criteria, 50 patients constituted the final study pop-
ulation (Figure 1 ).
Figure 1. Flow diagram.
The mean age at surgery was 31.1 ± 5.5 years, with the 30 - 35 age group being
most represented (34%). The majority were single (52%), had a university -level
education (74%), and resided in urban areas (84%). A striking 80% were nullipa-
rous (

3.2. Clinical Presentation and Phenotypes
Dysmenorrhea was nearly universal (96%), followed by chronic pelvic pain (54%)
and deep dyspareunia (66%). Infertility was a presenting complaint in 44% of pa-
tients (primary: 68.2%, secondary: 30.4%). Preoperative workup relied heavily on
pelvic ultrasound (34% had a specific mention), with fewer patients undergoing
CA-125 testing (18%) or MRI (8%).
The most frequent phenotypes encountered were superficial peritoneal endo-
metriosis (68%) and ovarian endometriomas (66%). Deep infiltrating endometri-
osis was present in 38% of cases, most commonly involving the uterosacral liga-
ments (73.7% of DIE cases) and causing partial or complete obliteration of the
pouch of Douglas (38% of all patients and 100% of DIE). Among the 27 patients
formally staged, moderate (Stage III, 44.4%) and severe (Stage IV, 25.9%) disease
were predominant (

3.3. Surgical Management
Laparoscopy was the primary surgical approach in 88% of cases (n = 44). For ovar-
ian endometriomas (n = 33), cyst drainage was systematically done, followed by
complete cyst wall excision (36.4%). Adhesiolysis was performed in 86% of pa-
tients. Surgical treatment of superficial peritoneal lesions (fulguration or excision)
was performed in 34% of cases. For DIE, nodule resection was undertaken in 24%
of all patients, with shaving of rectal nodules being the most frequent bowel pro-
cedure (10% of all patients). The intraoperative complication rate was low (6%),
consisting of hemorrhages requiring transfusion (

The mean hospital stay was 3.4 ± 0.9 days. Postoperative medical therapy was pre-
scribed for only 18% of patients (Triptorelin: 14%, Combined Oral Contracep-
tives: 4%).
Pain and quality of life outcomes showed dramatic improvement. The mean
preoperative VAS score of 9.5 ± 1.1 decreased significantly to 3.7 ± 2.7 postoper-
atively (p < 0.001). Among patients providing follow -up data, 75.7% reported a
decrease in pain intensity, and 24.3% reported complete resolution (Table 4 ).

4. Discussion
This study provides a comprehensive snapshot of the surgical management of en-
dometriosis in a Cameroonian urban setting, highlighting both the significant
burden of the disease and the tangible benefits of surgical intervention. Our find-
ings contribute to the sparse literature on endometriosis in Central Africa and
offer insights relevant for clinical practice and health system planning. These find-
ings confirm that women in this setting present at a young age but with advanced
disease, consistent with reports from other African data [4] [5].
The demographic profile of our cohort, young (mean age 31 years), predomi-
nantly nulliparous (80%), and highly educated, aligns with classic descriptions of
endometriosis patients globally, often characterized by delayed childbearing [12].
However, the strikingly high rates of nulliparity and nulligestation in our study
may reflect a dual reality: the disease ’s impact on fertility and potential sociocul-
tural factors influencing marriage and pregnancy timing in our context. The over-
whelming urban residence (84%) likely indicates disparities in healthcare access,
where rural women with chronic pelvic pain may never receive a definitive diag-
nosis.
The clinical presentation was dominated by severe pain, with near -universal
dysmenorrhea and high rates of deep dyspareunia and chronic pelvic pain. This
“pain triad” is a hallmark of endometriosis and its significant impact is quantita-
tively confirmed by the exceedingly high preoperative VAS (9.5/10) and EHP -5
scores [13]. The 44% prevalence of infertility is consistent with global estimates
I. Tompeen et al.
DOI: 10.4236/ojog.2026.161019 167 Open Journal of Obstetrics and Gynecology
and underscores endometriosis as a major cause of tubal and peritoneal factor
infertility [1] [14].
The distribution of disease phenotypes reveals important patterns. While su-
perficial disease and endometriomas were common, the 38% prevalence of DIE is
notable. This is higher than some early laparoscopic series but resonates with
more contemporary studies suggesting DIE is frequently underdiagnosed without
adequate expertise [15] [16]. The high proportion of moderate -to-severe rASRM
stages (70.3%) points to substantial diagnostic delay, a critical challenge in low -
resource settings where symptom normalization and limited access to specialized
care are prevalent [4] [8]. The reliance on ultrasound over MRI reflects resource
constraints, yet pelvic ultrasound, when performed by trained personnel, can ac-
curately diagnose endometriomas and suggest DIE [17].
The surgical approach was encouragingly minimally invasive, with 88% of pro-
cedures initiated laparoscopically. This demonstrates that advanced laparoscopic
surgery for complex benign gynecology is feasible in our setting with appropriate
training and infrastructure. The surgical techniques employed, however, reveal a
pragmatic approach. During laparoscopic management of ovarian endometrio-
mas, cyst drainage and hemostasis were performed using bipolar electrosurgical
energy. No ultrasonic or advanced energy devices were routinely available during
the study period. The preference for cyst drainage over excision for endometrio-
mas, while less optimal for preventing recurrence, may be influenced by concerns
over ovarian reserve and the technical difficulty of complete excision in the pres-
ence of dense adhesions [ 18] [19]. However, this may be a double -edged sword,
as drainage is associated with higher recu rrence rates and may contribute to the
35% of patients experiencing persistent pain. The relatively low rate of complete
resection of deep nodules (41.7% of those resected) highlights the technical com-
plexity of DIE surgery and the need for multidisciplinary teams, which may not
be routinely available [20].
The core finding of this study is the profound improvement in patient-reported
outcomes. The statistically and clinically significant reduction in pain (VAS de-
crease of 5.8 points) and the dramatic improvement in EHP -5 scores represent a
transformative effect of surgery on women’ s lives. These results are comparable
to or even exceed those reported in high -income settings following laparoscopic
excision, affirming the effectiveness of surgical care when it is accessible [21] [22].
The fact that only 18% of patients received postoperative hormonal suppression
(primarily Triptorelin) suggests that symptom relief was largely attributable to
surgery itself. This is an important consideration in contexts where long -term
medical therapy may be unaffordable or poorly tolerated. The low utilization of
postoperative hormonal therapy reflects a combination of factors specific to our
context, including financial constraints, limited access to long -term hormonal
treatments, patient preference, and the absence of standardized local postopera-
tive protocols. In addition, some providers prioritized surgical symptom relief
alone, particularly in patients desiring pregnancy, thereby limiting the prescrip-

DOI: 10.4236/ojog.2026.161019 168 Open Journal of Obstetrics and Gynecology
tion of suppressive hormonal therapyQuality -of-life improvement after surgery,
underscores that, even in resource -limited settings, surgical treatment can yield
meaningful patient -centered benefits. However, the modest fertility outcomes
highlight the need for earlier diagnosis and integrated fertility care.
The fertility outcomes, while based on a small subset, are cautiously promising,
with a 21.4% spontaneous conception rate. This aligns with studies showing im-
proved natural conception rates after surgery for mild-to-moderate endometriosis
[23]. The high rate of first -trimester miscarriage (66.6% of pregnancies) is con-
cerning and warrants further investigation into potential associated factors like
untreated inflammation or autoimmune phenomena linked to endometriosis [24]
[25].
This study has several strengths, including its focus on patient -centered out-
comes using validated tools (VAS, EHP -5), the combined data from public and
private sectors, and the detailed reporting of surgical phenotypes. However, limi-
tations must be acknowledged. The sample size, though robust for the local con-
text, limits subgroup analyses. The cross-sectional design with retrospective clin-
ical data collection is susceptible to information bias. The follow -up period for
fertility assessment was variable and likely insufficient to capture all potential con-
ceptions. We lacked a control group (e.g., medical management only) and data on
long-term recurrence rates. The reliance on telephone interviews for outcome as-
sessment, while practical, may introduce recall bias. This retrospective assessment
of baseline EHP-5 scores introduces a potential recall bias, as patients’ recollection
of preoperative quality of life may be influenced by their postoperative improve-
ment. This limitation should be considered when inte rpreting the magnitude of
change in EHP-5 scores.
5. Conclusion and Recommendations
This study demonstrates that endometriosis in Yaoundé presents as a severe, pain-
inducing condition, often diagnosed at advanced stages and primarily affecting
young nulliparous women. Surgical management, predominantly laparoscopic, is
strongly associated with significant improvements in pain and quality of life, rep-
resenting a vital therapeutic pathway.
To build upon these findings, the authors recommend the following actions:
- Enhance diagnostic capacity through training in advanced pelvic ultrasound
and improved access to MRI for suspected deep infiltrating endometriosis
(DIE) to reduce diagnostic delays.
- Strengthen surgical training and multidisciplinary care by supporting special-
ized training in laparoscopic deep excisional surgery and fostering collabora-
tion with colorectal and urological surgeons for complex DIE cases.
- Develop integrated postoperative care through standardized protocols for hor-
monal suppression and structured fertility counseling, bridging surgical and
reproductive medicine services.
- Promote patient advocacy and awareness via public and professional education
campaigns to destigmatize chronic pelvic pain and encourage early referral.

- Advance prospective research by establishing a national endometriosis registry
to track long -term surgical outcomes, recurrence rates, and fertility success,
thereby generating robust local evidence to inform policy and practice.
Effectively addressing endometriosis in Sub -Saharan Africa requires a con-
certed effort to bridge the gap between the significant unmet need and the demon-
strated potential of surgical care to restore health and hope.
