An ovarian cystectomy (surgical removal of an ovarian cyst) is a fertility-sparing gynecologic operation. The primary objective is to enucleate (peel out) the cyst wall intact from the surrounding ovarian stroma (tissue), allowing the healthy portion of the ovary to heal and retain endocrine and reproductive functions. It belongs to the specialty of gynecologic surgery and reproductive endocrinology.

According to the American College of Obstetricians and Gynecologists (ACOG Practice Bulletin No. 174), surgical intervention is indicated when an ovarian cyst is persistent, large, painful, complex on ultrasonography, or carries a risk of torsion, rupture, or neoplasia. Unlike an oophorectomy (complete removal of the ovary), a cystectomy preserves the organ's ability to produce hormones such as estrogen and progesterone and to release eggs (oocytes) during future menstrual cycles.

Ovarian cystectomy is performed under general anesthesia. The surgical steps are: 1. Patient positioning and induction: The patient is placed in the dorsal lithotomy position. 2. Abdominal entry: For laparoscopy, a primary incision is made at the umbilicus to introduce the laparoscope, followed by 2 to 3 accessory lower abdominal ports. For laparotomy, a transverse Pfannenstiel (bikini line) incision is made. 3. Inspection and lavage: The pelvis and abdomen are examined, and pelvic washings are collected for cytological analysis. 4. Cortical incision: The superficial layer (cortex) of the ovary overlying the cyst is carefully incised. 5. Cyst enucleation: Blunt and sharp dissection are used to peel the intact cyst capsule away from the underlying ovarian stroma. 6. Hemostasis and reconstructive closure: Bipolar electrocautery or fine absorbable sutures are used to arrest bleeding. The remaining ovarian tissue is edges-approximated or allowed to heal by secondary intention. 7. Specimen removal: The cyst tissue is placed in an endobag and extracted to prevent spillage. 8. Closure: Port sites or laparotomy incisions are sutured and dressed.

Clinical benefits of an ovarian cystectomy include:

• Fertility Preservation: Retains the structural and functional integrity of the target ovary, preserving future ovulation and biological childbearing potential.
• Symptom Relief: Resolves chronic pelvic pain, pressure, dyspareunia (painful intercourse), and urinary frequency caused by mass effect.
• Prevention of Surgical Emergencies: Eliminates the risk of ovarian torsion (twisting of the ovary cutting off blood supply) or catastrophic rupture.
• Definitive Histopathological Diagnosis: Provides clear microscopic analysis of the tissue to rule out ovarian malignancy or borderline tumors.
• Hormonal Maintenance: Avoids surgical menopause by preserving endogenous estrogen and progesterone production.

Recovery timelines vary depending on the surgical approach:

• Laparoscopic Cystectomy:
  • Hospital Stay: Outpatient (same-day discharge) or 24-hour observation.
  • Initial Recovery: Light activity within 48 hours; return to desk work in 1 to 2 weeks.
  • Full Recovery: Complete tissue healing and resume heavy lifting or vigorous exercise in 3 to 4 weeks.
• Laparotomy (Open Cystectomy):
  • Hospital Stay: 1 to 3 days.
  • Initial Recovery: Gradual walking by day 3; return to light work in 3 to 4 weeks.
  • Full Recovery: Complete abdominal wall strength restoration in 6 to 8 weeks.

Ovarian cystectomy is indicated for benign or low-malignant-potential ovarian lesions, including:

• Dermoid Cysts (Mature Cystic Teratomas): Benign germ cell tumors containing hair, skin, or teeth components.
• Endometriomas ("Chocolate Cysts"): Cysts formed by ectopic endometrial tissue secondary to endometriosis.
• Serous and Mucinous Cystadenomas: Benign epithelial neoplasms filled with clear fluid or gelatinous material.
• Persistent Simple Cysts: Fluid-filled sacs exceeding 5 to 7 cm that fail to resolve spontaneously over 8 to 12 weeks.
• Torsed or Ruptured Cysts: Surgical emergencies where a cyst causes twisting of the vascular pedicle or intra-abdominal bleeding.

Pre-operative evaluation includes a physical examination, transvaginal pelvic ultrasound, complete blood count, coagulation studies, and blood typing. Tumor markers (e.g., CA-125, HE4, CEA, beta-hCG, AFP) are ordered based on age and sonographic features. Fasting is required for 8 hours prior to surgery. Anticoagulant or antiplatelet medications are paused under physician direction. Prophylactic antibiotics and venous thromboembolism (VTE) prophylaxis (e.g., compression stockings or low-molecular-weight heparin) are administered according to surgical risk guidelines.

Complications of ovarian cystectomy stratified by severity include: Common/Mild: Post-operative pelvic soreness, abdominal bloating, shoulder tip pain from CO2 gas, minor vaginal bleeding, temporary fatigue. Uncommon: Port-site or incisional wound infection, urinary tract infection, hematoma formation, localized pelvic adhesion formation, transient reduction in ovarian reserve. Rare/Serious: Severe intra-abdominal hemorrhage, thermal or sharp injury to adjacent structures (bowel, bladder, ureter), conversion from laparoscopy to open laparotomy, anesthetic complications, complete loss of ovarian function, systemic infection/sepsis.

Pre-Procedure Evaluation

Patients undergo a comprehensive diagnostic workup, including a pelvic examination, transvaginal ultrasound (TVUS), and serum biomarker testing (such as CA-125 or HE4 when clinically indicated). Surgical planning determines whether a laparoscopic (minimally invasive) or laparotomy (open) approach is appropriate based on cyst size and risk stratification.

Surgical Phase

Under general anesthesia, the surgeon enters the peritoneal cavity, stabilizes the ovary, incises the ovarian cortex, and meticulously strips the cyst capsule from the underlying tissue. Hemostasis is achieved using precise bipolar cautery or sutures to minimize thermal damage to healthy eggs.

Immediate Recovery (Days 1–7)

Most laparoscopic procedures are performed on an outpatient basis. Patients experience mild to moderate pelvic discomfort, shoulder pain from carbon dioxide insufflation, and minor vaginal spotting. Normal ambulatory activity resumes within 24 to 48 hours.

Long-Term Recovery & Follow-Up

Full tissue healing occurs over 2 to 6 weeks. Histopathology reports are reviewed at a post-operative consultation (typically 2 to 4 weeks post-surgery) to confirm the benign nature of the tissue and guide any necessary long-term management, such as hormonal suppression for endometriomas.
