Aim: Pelvic exenteration surgery is an umbrella term for a multitude of operative techniques for locally advanced and recurrent pelvic malignancy. Currently, there is heterogeneity in the operative description that limits the interpretation of patient outcome and collaboration between units through standardized data collection. Our study aims to develop a consensus lexicon to describe the operative components of extended and exenteration pelvic surgery.
Method: This study adopted a mixed-methods approach using semi-structured interviews, questionnaires, focus groups and validation exercises involving pelvic exenteration experts from centres in the UK. Qualitative data were collected, and descriptive statistics are presented.
Results: We identified eight headings with 32 subheadings that encompass all components of the extent of the potential surgery. The lexicon was validated by 15 UK specialists. A 'high-complexity pelvic exenteration' was defined as encompassing 'conventional pelvic exenteration' with the extension of surgery to remove bony structures or the structures in the pelvic sidewall. Pelvic sidewall structures include major vessels, sciatic nerves and/or bone. Bony structures include the sacrum and/or pubic bones.
Conclusion: This pelvic exenteration lexicon will permit classification of the surgical approach used that will improve data synthesis, allow more accurate activity recording for audit and ultimately improved outcomes for patients.
Keywords: colorectal cancer; pelvic exenteration.
