OG34.5 | Major Operative Gynaecology — Summary & Reflection

KEY TAKEAWAYS

Major operative gynaecology encompasses abdominal (TAH, myomectomy, staging laparotomy), vaginal (VH, pelvic floor repair, Fothergill's), and endoscopic (laparoscopy, hysteroscopy) approaches. Key learning points: (1) The ureter has three danger points in gynaecological surgery: near the IP ligament, under the uterine artery, and near the lateral vaginal fornix — always identify before clamping. (2) TAH pedicle sequence: round ligament → IP/utero-ovarian ligament → broad ligament → bladder reflection → uterine artery → cardinal/uterosacral → vaginal cuff. (3) Wertheim's radical hysterectomy for cervical cancer adds parametrectomy + lymphadenectomy + upper vaginal cuff. (4) Vaginal route preferred for prolapse (small, mobile uterus); Fothergill's operation preserves the uterus in cervical elongation. (5) Laparoscopy: Veress needle entry — confirm by drop test and low initial pressure; CO₂ pressure 12–15 mmHg. (6) Hysteroscopy: fluid deficit threshold 1,000 mL (normal saline) or 750 mL (hypotonic media) — stop immediately to prevent fluid overload/hyponatraemia. (7) Post-operative complications: ureteric injury (loin pain + raised creatinine = ligature; watery discharge = fistula); DVT prophylaxis is mandatory; vesicovaginal fistula = delayed repair at 6–12 weeks.

REFLECT

Reflect on the concept of 'surgical anatomy' — the knowledge of where structures are during an operation, which may differ significantly from the anatomy of a cadaveric dissection. Adhesions, anatomical variants, large tumours, and obesity all distort the normal surgical field. After observing a major gynaecological operation, consider: which anatomical structure did the surgeon specifically seek to identify before each key step? At what moment did you feel least certain about where the ureter was? What systems in the operating theatre are in place to prevent errors — from the consent form, to the pre-operative marking, to the scrub nurse's instrument checks, to the intraoperative monitoring of fluid deficit during hysteroscopy? How do these systems reflect the principle that safe surgery is a team sport, not an individual skill?
