Ovarian cancer surgery serves two fundamental goals in gynecologic oncology: establishing exact anatomical disease extent (surgical staging) and eliminating all visible tumor deposits (cytoreductive surgery). Because epithelial ovarian cancer spreads predominantly by direct shedding of cancer cells across the peritoneal cavity, surgical management frequently extends beyond the reproductive organs to involve the omentum, peritoneum, and adjacent abdominal viscera. Clinical practice guidelines from the National Comprehensive Cancer Network (NCCN 2024) and the European Society of Gynaecological Oncology (ESGO 2023) emphasize that achieving complete cytoreduction—removing all visible tumor—is the single strongest clinical predictor of overall survival.

Ovarian cancer surgery begins with an abdominal incision (typically vertical midline laparotomy). The surgeon collects peritoneal fluid or washings for cytology. Systemic abdominal exploration evaluates all peritoneal surfaces, liver, diaphragm, omentum, retroperitoneum, and bowel. For early-stage disease, standard procedure involves total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic and para-aortic lymphadenectomy, infracolic omentectomy, and multiple peritoneal biopsies. For advanced disease, maximal cytoreduction is performed, which may require en bloc pelvic resection, diaphragm stripping, bowel resection, or splenectomy to remove all gross tumor.

Primary evidence-based benefits of ovarian cancer surgery include accurate FIGO disease staging, definitive histological confirmation, immediate tumor burden reduction, relief of mechanical bowel or bladder compression, reduction of malignant ascites accumulation, and significant prolongation of progression-free and overall survival when complete cytoreduction is achieved (ESGO 2023 guidelines).

Inpatient hospitalization ranges from 3 to 7 days depending on surgical extent. Initial wound healing occurs over 2 to 3 weeks. Full physical recovery and return to baseline functional status typically require 6 to 8 weeks following open laparotomy. Adjuvant chemotherapy routinely commences between 3 and 6 weeks post-operatively once abdominal incisional integrity and bowel function are restored.

Ovarian cancer surgery is indicated for suspected or confirmed primary epithelial ovarian carcinoma, fallopian tube carcinoma, primary peritoneal carcinoma, malignant ovarian germ cell tumors, sex cord-stromal tumors, and recurrent ovarian malignancies. It is also utilized for prophylactic risk reduction in individuals carrying high-penetrance genetic mutations, such as BRCA1, BRCA2, or Lynch syndrome genes.

Pre-procedure preparation involves blood chemistry, complete blood count, coagulation profile, and serum tumor markers (CA-125, HE4, CEA, CA19-9). Imaging includes contrast-enhanced CT of the chest, abdomen, and pelvis, or MRI. Mechanical and oral antibiotic bowel preparation may be ordered. Cardiovascular and pulmonary clearance, nutritional assessment, and pre-operative anesthesia evaluation are completed. Patients fast for 8 hours prior to surgery.

Complications stratified by severity include: Common/Mild: Surgical site infection, wound hematoma, transient ileus, urinary tract infection, postoperative fatigue. Moderate: Deep vein thrombosis, pulmonary embolism, lymphocele, broad incisional hernia, severe postoperative pain. Rare/Severe: Bowel perforation, anastomotic leak requiring stoma creation, ureteral or bladder injury, major hemorrhage requiring blood transfusion, acute kidney injury, sepsis, and perioperative mortality (<1-2%).

The clinical surgical journey begins with comprehensive pre-operative staging, including high-resolution imaging, tumor marker assays, and medical optimization. Patients undergo exploratory laparotomy or minimally invasive surgery under general anesthesia. Intraoperatively, the surgical team performs formal abdominal exploration, tissue resection, frozen section analysis, and pelvic cytoreduction. Immediately following surgery, patients transition to an inpatient surgical unit or intensive care unit for hemodynamics monitoring, pain control, bowel function recovery, and early mobilization. Outpatient recovery involves wound care, physical rehabilitation, and timely initiation of adjuvant systemic chemotherapy, typically within 3 to 6 weeks post-operatively.
