Hysterectomy — structured SAQ (15 marks)

(a) Route selection and named evidence base (3 marks)

One mark for the route chosen with patient-specific justification, one for the named alternative, one for the named evidence.

• Route chosen: laparoscopic hysterectomy (with conversion to laparotomy if anatomy is hostile). Justification: 10-week bulky fibroid uterus is feasible laparoscopically in trained hands; one previous Caesarean section increases bladder injury risk but the bladder flap can be developed safely with sharp dissection; vaginal route is the Cochrane preferred route when feasible but the 10-week size reduces the chance of a successful vaginal approach in this patient.^[1]
• Named alternative: vaginal hysterectomy (the Cochrane preferred route when feasible, PMID 37642285).
• Named evidence base: the Cochrane Pickett 2023 review (PMID 37642285) — 63 RCTs, 6811 women; vaginal hysterectomy superior to abdominal in faster return to normal activities (MD −10.91 days); laparoscopic advantages over abdominal with shorter recovery but higher urinary tract injury (OR 2.16, 95% CI 1.19–3.93).

(b) Steps of total laparoscopic hysterectomy in order (4 marks)

One mark for each sequence of steps with named anatomical landmarks. ^[9]

• Step 1 — Identification of the ureter at the pelvic brim (crossing the bifurcation of the common iliac artery, visible through the medial leaf of the broad ligament).
• Step 2 — Division of the round ligament and opening of the anterior leaf of the broad ligament peritoneum.
• Step 3 — Opening of the pararectal and paravesical spaces (pararectal medial to the internal iliac artery and lateral to the ureter; paravesical medial to the obliterated umbilical artery).
• Step 4 — Skeletonisation of the ureter down to the uterine artery and identification of the lateral cervical branch of the uterine artery crossing over it.
• Step 5 — Division of the uterine artery at its origin from the anterior trunk of the internal iliac.
• Step 6 — Development of the bladder flap off the lower uterine segment; sharp dissection in the midline for the prior Caesarean section.
• Step 7 — Division of the utero-ovarian ligament (or the infundibulopelvic ligament if oophorectomy) and opening of the rectovaginal septum.
• Step 8 — Division of the uterosacral ligaments at the level of the cervix.
• Step 9 — Colpotomy along the Koh cup (or vaginal tube) with circumferential incision of the vagina.
• Step 10 — Specimen retrieval vaginally or by morcellation in a containment bag.
• Step 11 — Closure of the vaginal cuff with continuous barbed suture (V-Loc or Stratafix) or interrupted figure-of-eight absorbable suture.

(c) Immediate response to brisk bleeding at the lateral cervical step (4 marks)

One mark for stopping, one for identification, one for the principle of haemostasis, one for confirming ureteric integrity.

• Stop and apply pressure with a swab; do not blind-diathermy near the ureter; apply pressure to allow visualisation.^[9]
• Identify the bleeding vessel — the lateral cervical branch of the uterine artery crossing over the ureter; trace the ureter above and below the bleeding point.
• Principle of haemostasis — named-vessel control: suture-ligate with fine absorbable suture (4-0 or 5-0 PDS or Vicryl) or apply a clip; bipolar diathermy is acceptable if the ureter is identified and away from the field; never use unipolar diathermy near the ureter.
• Confirm ureteric integrity at the end of the procedure: intra-operative cystoscopy with indigo carmine and furosemide to demonstrate bilateral ureteric efflux; check postoperative creatinine on day 2.

(d) Day 5 presentation with sudden pelvic pain and visible small bowel in the vagina (4 marks)

One mark for the diagnosis, one for resuscitation, one for return to theatre and repair, one for postoperative plan.

• Diagnosis: vaginal cuff dehiscence with bowel evisceration — a surgical emergency.^[1]
• Immediate resuscitation: IV access, fluids, analgesia, antiemetics, nil by mouth, broad-spectrum intravenous antibiotics (e.g. cefazolin plus metronidazole), group and screen, anaesthetic review.
• Return to theatre for repair: examination under anaesthesia, inspection of the small bowel for serosal tears or ischaemia, return of the bowel to the abdomen, repair of the cuff with interrupted figure-of-eight absorbable sutures (e.g. 0 Vicryl); consider laparoscopic or abdominal approach if vaginal access is inadequate; general surgical consult if bowel injury identified.
• Postoperative plan: enhanced observation, nil by mouth until bowel function returns, IV antibiotics, VTE prophylaxis, smoking cessation counselling, advice to avoid intercourse and heavy lifting for 6–8 weeks, follow-up to confirm healing and to plan cervical screening if subtotal was not performed.
