I now have everything needed to write a thorough case presentation guide. Here it is:
CASE PRESENTATION GUIDE
Patient: Reputana, Glory Grace Duran | 43/F | G1P1 (1001)
Brokenshire Medical Center, Davao City | June 24, 2026
I. OBSTETRIC-GYNECOLOGIC HISTORY INTERPRETATION
G1P1 (1001) follows the TPAL system:
- T = 1 (Term delivery)
- P = 0 (Preterm)
- A = 0 (Abortion)
- L = 1 (Living child)
She has completed childbearing, which is a key factor in the surgical decision-making.
II. CHIEF COMPLAINT AND ADMITTING DIAGNOSIS
Chief Complaint: Intermenstrual spotting
Admitting Diagnoses (pre-op):
- Mild Anemia Secondary to Acute Blood Loss
- Abnormal Uterine Bleeding (AUB) Secondary to Endometrial Polyp vs. Endometrial Pathology
- Ovarian New Growth, Bilateral - Probably Malignant
Post-Operative (Final) Diagnoses:
- Mild Anemia Secondary to Acute Blood Loss - Corrected
- AUB Secondary to Endometrial Polyp
- Pelvic Endometriosis Stage IV
- Ovarian Abscess (confirmed by Frozen Section Biopsy)
III. MAIN DIAGNOSIS - PELVIC ENDOMETRIOSIS STAGE IV
This is the primary driver of both the complexity and the surgical approach used.
What is Endometriosis?
Endometriosis is a chronic inflammatory condition defined by the presence of endometrium-like tissue outside the uterine cavity, most commonly affecting the pelvic organs and peritoneum. The leading pathogenic theory is retrograde menstruation. It affects approximately 5-10% of women of reproductive age (Bailey & Love's Surgery, 28th ed., p. 1603).
ASRM Revised Classification (rASRM, 1996) - Stage IV "Severe"
The American Society for Reproductive Medicine uses a point-based scoring system (total 150 points):
| Stage | Points | Description |
|---|
| I - Minimal | 1-5 | Isolated implants, no adhesions |
| II - Mild | 6-15 | Superficial implants <5 cm, no adhesions |
| III - Moderate | 16-40 | Many deep implants, small ovarian cysts, filmy adhesions |
| IV - Severe | >40 | Many deep implants, large bilateral endometriomas, dense adhesions |
This patient scored Stage IV based on:
- Bilateral large endometriomas (R: 11 cm, L: 10 cm)
- Dense adhesions of the right ovary to the pelvic sidewall, omentum, rectosigmoid, and posterior uterus
- Involvement of the uterosacral ligaments
- Fixation of pelvic organs (the laparotomy found extensive adhesions requiring enterolysis)
Gross/Intraoperative Correlation
The grayish-green foul fluid that egressed when the masses ruptured during adhesiolysis, combined with the red-brown internal capsule with rough inner walls on cut section, indicates:
- Endometriomas typically contain "chocolate" brown, old hemorrhagic fluid
- The superimposed infection of the endometriomas converted them into ovarian abscesses
- This explains the fourth post-op diagnosis: Ovarian Abscess by Frozen Section
The image below (Bailey & Love's, p. 1603) shows exactly this intraoperative appearance of bilateral ovarian endometriomas with dense pelvic adhesions:
IV. HOW THE DIAGNOSIS WAS REACHED
Preoperative Workup Led To This Diagnosis
The clinical picture that pointed toward Stage IV Endometriosis / complicated ovarian mass included:
History:
- 43-year-old woman (reproductive age peak)
- Intermenstrual spotting (AUB)
- Likely history of chronic pelvic pain / dysmenorrhea (common with Stage IV disease)
Physical Examination:
- Signs suggestive of endometriosis include: pelvic tenderness, fixed retroverted uterus, tender uterosacral ligaments, or enlarged ovaries (Bailey & Love's, p. 1602)
- A bilateral adnexal mass would have been palpable / confirmed on imaging
Imaging (Transvaginal Ultrasound / Imaging):
- The admitting diagnosis of "Ovarian New Growth Bilateral - Probably Malignant" indicates bilateral complex cystic masses were already identified
- TVS can detect endometriomas (thick-walled, homogeneous ground-glass echogenicity) vs. simple cysts
- MRI can detect hemosiderin deposits (deep endometriosis)
Frozen Section Biopsy (Intraoperative):
- The specimen was sent intraoperatively for frozen section - this is standard when there is concern for malignancy in an ovarian mass
- Result came back as Ovarian Abscess (not malignant), confirming the infected endometrioma rather than an ovarian malignancy
Why Biopsy Was Needed:
The admitting differential included probable malignancy because:
- Bilateral masses
- Large size (10-11 cm)
- Dense adhesions to surrounding organs
- Patient age 43 (peri-menopausal risk window)
- CA-125 would typically be elevated in both endometriosis and ovarian cancer
V. DIFFERENTIAL DIAGNOSIS FOR BILATERAL OVARIAN MASSES
Per Berek & Novak's Gynecology and general gynecologic oncology principles:
| Differential | Evidence For | Evidence Against |
|---|
| Endometrioma (bilateral) | Age, dense adhesions, brown fluid, "chocolate cyst" appearance, rough inner walls | - |
| Tubo-Ovarian Abscess | Foul green fluid, infected contents, dense adhesions | No classic PID history noted |
| Epithelial Ovarian Carcinoma | Bilateral, large, dense adhesions, age | Frozen section NEGATIVE for malignancy |
| Borderline Ovarian Tumor | Bilateral, cystic | Frozen section negative |
| Mucinous/Serous Cystadenoma | Large unilocular cysts | Contents were brown/green, not clear/mucinous |
Working diagnosis pre-op: AUB + Bilateral Ovarian New Growth Probably Malignant - which included ovarian carcinoma as the most feared differential.
Final diagnosis post-op / frozen section: Stage IV Pelvic Endometriosis with bilateral infected endometriomas (ovarian abscess).
VI. SECONDARY DIAGNOSIS: AUB SECONDARY TO ENDOMETRIAL POLYP
Definition
An endometrial polyp is a focal overgrowth of endometrial glands and stroma arising from the basalis layer, forming a pedunculated or sessile projection into the uterine cavity.
Clinical Presentation
- Intermenstrual spotting (this patient's chief complaint)
- Heavy menstrual bleeding
- Postmenopausal bleeding
Diagnosis
Found on cut section of the uterus: "An endometrial polyp was noted, measuring 1 cm x 0.5 cm" - this was confirmed at gross pathology.
Preoperatively, the workup would typically include:
- Transvaginal ultrasound (showing echogenic endometrial lesion)
- Saline infusion sonography (SIS) - more sensitive
- Hysteroscopy (gold standard - allows direct visualization and resection)
- Endometrial sampling (biopsy to rule out endometrial carcinoma/hyperplasia)
Why Surgery for AUB Was Appropriate
Per Berek & Novak's Gynecology (p. 1411): "Endometrial sampling should be performed before hysterectomy. Hysterectomy should be reserved for patients who do not respond to or cannot tolerate medical therapy." Since this patient also had Stage IV endometriosis with bilateral abscess formation requiring surgical management, concurrent treatment of the AUB/polyp was appropriate within the same operation.
VII. WHY THE SURGERY WAS DONE - SURGICAL INDICATIONS
The procedure performed was: Exploratory Laparotomy + Extensive Adhesiolysis + Enterolysis + Total Abdominal Hysterectomy with Bilateral Salpingo-oophorectomy (TAH-BSO) + Appendectomy
Indications (Multiple Converging):
- Stage IV Pelvic Endometriosis - bilateral large endometriomas (10-11 cm), extensive dense adhesions to rectosigmoid, pelvic sidewall, omentum
- Completed Childbearing (G1P1, age 43) - fertility preservation was no longer a consideration
- Failed / Inappropriate Candidate for Medical Management - large bilateral masses cannot be managed medically
- Bilateral Ovarian Abscesses - infected endometriomas required removal; conservative management (antibiotics alone) is insufficient for large abscess
- AUB with Endometrial Polyp - concurrent uterine pathology
- Suspicion of Malignancy - bilateral masses with dense adhesions required definitive surgical staging/resection
Why TAH-BSO Specifically (Not Just Cystectomy)?
Per Bailey & Love's Surgery (p. 1604): "For a woman who has completed her family, hysterectomy plus bilateral salpingo-oophorectomy with total excision of endometriotic disease offers a good chance of cure."
Per Berek & Novak's Gynecology (p. 1413 / Chapter 26): "Bilateral salpingo-oophorectomy, with or without hysterectomy, should be performed only in patients who do not respond to conservative surgical or medical therapy. Most patients with endometriosis who require hysterectomy have unrelenting pelvic pain or dysmenorrhea."
The bilateral oophorectomy eliminates the estrogen drive that sustains endometriosis, making it the most definitive treatment in a woman who has completed her family.
Why Appendectomy?
The appendix was removed likely because:
- Dense adhesions to the right adnexa / rectosigmoid (right ovarian mass adherent to rectosigmoid)
- Incidental appendectomy is common practice in gynecologic surgery when the appendix is involved in adhesions or when there is concern about endometriosis involvement
- Standard of care recommendation in most gynecologic oncology-level operations
VIII. SURGICAL TECHNIQUE - STEP-BY-STEP CORRELATION
| Operative Step | Why It Was Done |
|---|
| Vertical infraumbilical incision | Provides wider access for large pelvic masses (11 cm R, 10 cm L ovaries), extensive adhesions; allows entry into both pelvic and upper abdominal compartments |
| Extensive adhesiolysis + enterolysis | Right ovary densely adherent to pelvic sidewall, omentum, rectosigmoid, posterior uterus - adhesions must be freed to mobilize organs safely |
| Intraoperative Surgery referral | Right mass ruptured with bowel involvement - colorectal/general surgery consulted for rectosigmoid adhesiolysis |
| Round ligament division | Standard first step in TAH - opens anterior leaf of broad ligament |
| Infundibulopelvic ligament ligation | Contains ovarian vessels - must be ligated before oophorectomy (BSO) |
| Ureteral identification | Essential in Stage IV disease - ureters are commonly displaced by adhesions and endometriotic nodules; injury would cause ureterovaginal fistula |
| Uterine vessel ligation (Heaney clamps) | Standard TAH technique at level of uterine isthmus |
| Uterosacral ligament division | Frees uterus posteriorly; uterosacral ligaments are a common site of deep endometriosis |
| Frozen section biopsy | To rule out ovarian malignancy intraoperatively before completing surgery |
| Peritoneal washing | Cytological sampling; also part of surgical oncology staging protocol |
IX. POST-OPERATIVE DIAGNOSES EXPLAINED
| Diagnosis | Explanation |
|---|
| Mild Anemia - Corrected | Blood loss from AUB was pre-existing; 900 cc intraoperative blood loss likely required replacement; resolved post-op |
| AUB Secondary to Endometrial Polyp | 1 cm polyp confirmed on cut section; removed with uterus |
| Pelvic Endometriosis Stage IV | Bilateral endometriomas, dense adhesions, involvement of rectosigmoid and pelvic sidewall |
| Ovarian Abscess by Frozen Section | Superinfected endometrioma confirmed by intraoperative frozen section; grayish-green foul fluid is the clinical hallmark |
X. MANAGEMENT SUMMARY (Comprehensive Gynecology 8th Ed Framework)
Pre-operative
- Correct anemia (iron supplementation / transfusion as needed)
- Imaging: TVS ± MRI for mass characterization
- Tumor markers: CA-125, CEA (to support/exclude malignancy differential)
- Endometrial sampling (SIS, hysteroscopy, or office biopsy for AUB evaluation)
- Bowel prep may be required given rectosigmoid adhesion anticipation
- Anesthesia: Combined spinal-epidural (as used) appropriate for prolonged pelvic surgery
- Informed consent: risks include bowel/bladder/ureteral injury, conversion, blood transfusion
Intraoperative
- Laparotomy (vertical midline) for large bilateral masses
- Systematic adhesiolysis with ureteral identification
- Frozen section of ovarian mass to guide extent of surgery
- TAH + BSO + adhesiolysis + enterolysis + appendectomy
- Peritoneal washings
Post-operative
- Histopathology of all specimens (uterus, cervix, bilateral tubes + ovaries) - results pending
- Monitor for: fever (abscess spillage), ileus (bowel adhesiolysis), urinary complications
- HRT (hormone replacement therapy) discussion: bilateral oophorectomy causes surgical menopause; HRT is considered in young women with BSO for benign disease, but in endometriosis, unopposed estrogen may stimulate residual implants - decision is individualized
- Antibiotic coverage post-op (given abscess / infected endometrioma)
- Long-term follow-up: recurrence rate after TAH-BSO for endometriosis is low (approximately 10%)

The Big Picture in 3 Sentences:
A 43-year-old G1P1 (completed childbearing) presented with intermenstrual spotting and was found to have bilateral large complex ovarian masses (10-11 cm) that were initially suspected to be malignant. Intraoperatively, Stage IV pelvic endometriosis was confirmed - her entire pelvis was frozen with adhesions connecting the ovaries to the bowel, pelvic sidewall, and uterus, and both endometriomas had superimposed infection (ovarian abscesses, confirmed by frozen section). Since she had completed her family, the definitive treatment - TAH-BSO with adhesiolysis and appendectomy - was the correct and indicated surgery, offering the best chance of cure.
3 Most Important Points for Your Presentation:
-
Main diagnosis is Stage IV Endometriosis (not the AUB, not the anemia - those are secondary). Stage IV is confirmed by the ASRM rASRM score >40 points: bilateral endometriomas >3 cm + dense adhesions.
-
Surgery was indicated because: (a) Stage IV disease unresponsive to/beyond conservative management, (b) bilateral ovarian abscesses requiring source control, (c) bilateral masses with malignancy concern needing frozen section, and (d) completed childbearing making TAH-BSO the definitive cure.
-
The AUB/polyp was a concurrent finding - the intermenstrual spotting that brought her in was caused by the 1 cm endometrial polyp, confirmed on cut section. This was simultaneously treated by the hysterectomy.
