Significance: The role of colonoscopy in the preoperative evaluation of suspected ovarian cancer is not well-defined. While it is routinely performed in some institutions, there are currently no established guidelines on preoperative colonoscopy in patients with gynecologic malignancies. While colonoscopy can identify synchronous cancers and other non-neoplastic lesions, there are no published local data in terms of its diagnostic yield. This study aims to evaluate the role of preoperative colonoscopy in patients suspected of having ovarian cancer.
Methodology: This retrospective cross-sectional study reviewed medical records of adults (aged 19 and above) with suspected ovarian cancer who underwent colonoscopy at a tertiary university hospital from January 2021 to December 2023. Data collected included demographics, gastrointestinal symptoms, tumor markers, and colonoscopy findings. Descriptive statistics and appropriate tables and graphs were used to summarize the data.
Results: A total of 186 patients were analyzed. The most common findings were extrinsic compression, colonic polyps, diverticulosis, and hemorrhoids. Only 4% of colonoscopies revealed masses, 2% of which are primary colonic neoplasm on biopsy. Colonoscopies performed for suspected ovarian malignancy had a lower cecal intubation rate with lower Boston Bowel Preparation Scores than published standards.
Conclusion: While the primary indication for colonoscopy is to rule out colorectal extension of ovarian tumors, only 1% of procedures were consistent with a tumor extension. These findings suggest a need to reevaluate current practices regarding the routine use of colonoscopy in th
