For surgical staging in ovarian or fallopian tube malignancy, which procedure is typically involved?

The procedure typically involved in surgical staging for ovarian or fallopian tube malignancies is total abdominal hysterectomy with bilateral salpingo-oophorectomy (TAH BSO). This surgical approach is used for comprehensive evaluation and staging of these cancers.

During TAH BSO, the uterus, cervix, both ovaries, and fallopian tubes are removed. This allows for thorough pathological examination of the removed tissues, which is critical in determining the stage of the disease and providing the necessary information for treatment planning. The procedure also helps in assessing the extent of the disease, as the surgeon can visualize and potentially sample nearby structures and lymph nodes as necessary.

Other procedures, such as endometrial biopsy and hysteroscopy, are more focused on the uterine cavity and are not suitable for staging ovarian or fallopian tube malignancies. Laparoscopy, while it can be used to evaluate and stage pelvic cancers, typically does not allow for the complete surgical staging that TAH BSO provides. Therefore, TAH BSO stands out as the definitive procedure in this context.
