Question

Difficulty: MediumGynecologic Procedures and Complications

Match each postoperative clinical presentation following a gynecologic procedure to the most likely underlying surgical complication or injured structure.

  • Foot drop and numbness over the anterolateral leg after prolonged placement in the high lithotomy positionCommon fibular (peroneal) nerve compression
  • Sharp, burning pain radiating to the mons pubis and labia majora following fascial closure of a low transverse abdominal (Pfannenstiel) incisionIlioinguinal nerve entrapment
  • Weakness in thigh adduction and decreased sensation over the medial thigh following a retroperitoneal pelvic lymphadenectomyObturator nerve injury
  • New-onset unilateral flank pain and fever with preserved overall urine output 3 days after clamping the cardinal ligaments during a hysterectomyDistal ureteral ligation
  • Painless, continuous leakage of clear fluid from the vaginal vault with normal voiding habits 14 days after a total abdominal hysterectomyVesicovaginal fistula formation

Answer

The presentations correctly map as follows: Lithotomy position issues map to common fibular nerve compression; Pfannenstiel incision pain maps to ilioinguinal nerve entrapment; Lymphadenectomy deficits map to obturator nerve injury; Cardinal ligament clamping complications map to distal ureteral ligation; and delayed continuous vaginal leakage maps to vesicovaginal fistula formation.
Each clinical presentation classically aligns with specific anatomical vulnerabilities encountered during gynecologic procedures. Nerve injuries are tied directly to patient positioning (common fibular) or localized dissection sites (ilioinguinal, obturator). Urinary tract injuries correlate with dissection near the cardinal ligaments (ureter) and the vesicouterine reflection (bladder/fistula).

Step-by-Step Solution

1
Analyze the surgical position or specific operative step mentioned in each presentation to identify the anatomical structures placed at risk.
Lithotomy positioning puts superficial lower extremity nerves at risk; Pfannenstiel fascial closure risks abdominal wall nerves; deep retroperitoneal dissection risks the obturator nerve; and cardinal ligament clamping risks the distal ureter.
Gynecologic procedures have highly stereotyped complications directly based on the anatomic relationships and physical exposures of the female pelvis.
2
Correlate the postoperative signs and symptoms with the physiologic function of the suspected injured structure.
Adductor weakness correlates with the obturator nerve; foot drop with the common fibular nerve; unilateral flank pain with ureteral obstruction; and continuous incontinence with a pathological fistula tract.
Identifying the precise functional or sensory deficit confirms the specific anatomical injury.
