Gynecologic Surgery

Gynecologic Surgery US Medical PG Question 1: A 33-year-old woman comes to the emergency department because of a 1-hour history of severe pelvic pain and nausea. She was diagnosed with a follicular cyst in the left ovary 3 months ago. The cyst was found incidentally during a fertility evaluation. A pelvic ultrasound with Doppler flow shows an enlarged, edematous left ovary with no blood flow. Laparoscopic evaluation shows necrosis of the left ovary, and a left oophorectomy is performed. During the procedure, blunt dissection of the left infundibulopelvic ligament is performed. Which of the following structures is most at risk of injury during this step of the surgery?

• A. Bladder trigone
• B. Uterine artery
• C. Kidney
• D. Ureter (Correct Answer)

Gynecologic Surgery Explanation: ***Ureter*** - The **infundibulopelvic ligament** (also known as the suspensory ligament of the ovary) contains the **ovarian artery and vein** and is in close proximity to the ureter as it crosses the pelvic brim. - During dissection or clamping of this ligament, especially in an emergency setting or when anatomy is distorted (e.g., by an enlarged ovary or edema), the **ureter** is highly susceptible to injury. *Bladder trigone* - The **bladder trigone** is the smooth triangular region at the base of the bladder, formed by the openings of the ureters and the internal urethral orifice. - It is not directly adjacent to the infundibulopelvic ligament and is therefore at a comparably lower risk of injury during dissection of this ligament. *Uterine artery* - The **uterine artery** travels within the cardinal ligament and supplies the uterus; it is located more medially and inferiorly within the broad ligament. - While important in pelvic surgery, it is not in the immediate vicinity of the infundibulopelvic ligament dissection itself. *Kidney* - The **kidneys** are retroperitoneal organs located much higher in the abdominal cavity, far superior to the pelvis. - They are not at risk of direct injury during pelvic surgery involving the infundibulopelvic ligament.

Gynecologic Surgery US Medical PG Question 2: A 60-year-old post-menopausal female presents to her gynecologist with vaginal bleeding. Her last period was over 10 years ago. Dilation and curettage reveals endometrial carcinoma so she is scheduled to undergo a total abdominal hysterectomy and bilateral salpingo-oophorectomy. During surgery, the gynecologist visualizes paired fibrous structures arising from the cervix and attaching to the lateral pelvic walls at the level of the ischial spines. Which of the following vessels is found within each of the paired visualized structure?

• A. Vaginal artery
• B. Superior vesical artery
• C. Uterine artery (Correct Answer)
• D. Artery of Sampson
• E. Ovarian artery

Gynecologic Surgery Explanation: ***Uterine artery*** - The paired fibrous structures described are the **cardinal ligaments (transverse cervical ligaments)**, which contain the **uterine arteries** as they course towards the uterus. - The uterine artery, a branch of the **internal iliac artery**, crosses over the **ureter** within the cardinal ligament—a critical anatomical relationship during gynecological surgery ("water under the bridge"). - This is the primary vessel within the cardinal ligament and the key vascular structure at risk during hysterectomy. *Vaginal artery* - The vaginal artery typically branches from the **uterine artery** or directly from the **internal iliac artery**, but it is not the main vessel found within the cardinal ligament. - It primarily supplies the **vagina**, not contained within the cardinal ligament support structure. *Superior vesical artery* - The superior vesical artery supplies the **upper part of the bladder** and originates from the **umbilical artery** (a branch of the internal iliac artery). - It is not anatomically associated with the cardinal ligament or uterine support structures. *Artery of Sampson* - The Artery of Sampson is a branch of the **uterine artery** that anastomoses with the **ovarian artery** within the **broad ligament**, not the cardinal ligament. - It is a minor vessel involved in the dual blood supply to the ovaries and uterus, not a primary structure within the cardinal ligament. *Ovarian artery* - The ovarian artery originates directly from the **abdominal aorta** and travels within the **suspensory ligament of the ovary (infundibulopelvic ligament)**, not the cardinal ligament. - It supplies the **ovaries and fallopian tubes**, with a trajectory that is anatomically distinct from structures within the cardinal ligament.

Gynecologic Surgery US Medical PG Question 3: A 16-year-old boy presents to the emergency department after a skateboarding accident. He fell on a broken bottle and received a 4 cm wound on the dorsal aspect of his left hand. His vitals are stable and he was evaluated by the surgeon on call who determined that suturing was not required. After several weeks the wound has almost completely healed (see image). Which of the following is the correct description of this patient's wound before healing?

• A. Incised wound (Correct Answer)
• B. Abrasion
• C. Laceration
• D. Avulsion
• E. Puncture

Gynecologic Surgery Explanation: ***Incised wound*** - An **incised wound** is caused by a sharp object, such as a broken bottle, resulting in a clean, straight cut with well-defined edges and minimal tissue damage. - The characteristics of the injury (sharp object mechanism, 4 cm linear wound) and the clinical decision that suturing was not required suggest a relatively clean incised wound with edges that could approximate well. - Incised wounds typically heal with **fine linear scars** as shown in the image, especially when the edges are well-approximated. *Abrasion* - An abrasion is a **superficial wound** caused by friction or scraping, leading to removal of the epidermis and sometimes the superficial dermis. - This mechanism does not match the described injury from a broken bottle, and abrasions produce broad, shallow wounds rather than deep linear cuts. - Abrasions heal with minimal scarring and would not produce the linear scar pattern shown. *Laceration* - A laceration is a wound with **irregular, torn edges** typically caused by blunt force trauma or crushing injury. - While broken glass can sometimes cause lacerations, the description of a clean "4 cm wound" from falling on a broken bottle more strongly suggests a sharp cutting mechanism rather than tearing. - Lacerations have jagged edges with more tissue damage and typically require debridement or careful closure. *Avulsion* - An **avulsion** involves forcible tearing away of tissue, often resulting in significant tissue loss with irregular, gaping wounds. - This injury pattern is much more severe than described and would typically require complex surgical management, including possible skin grafting. - The mechanism (falling on broken glass) and the relatively straightforward healing do not support an avulsion injury. *Puncture* - A puncture wound is caused by a **pointed object** penetrating the skin, creating a small entry hole with depth greater than width. - The description of a "4 cm wound" indicates a linear length, not a deep narrow penetration typical of puncture wounds. - Puncture wounds carry high infection risk and would not produce the linear scar pattern shown in the image.

Gynecologic Surgery US Medical PG Question 4: A 42-year-old woman, gravida 3, para 3 comes to the physician because of a 14-month history of prolonged and heavy menstrual bleeding. Menses occur at regular 28-day intervals and last 7 days with heavy flow. She also feels fatigued. She is sexually active with her husband and does not use contraception. Vital signs are within normal limits. Pelvic examination shows a firm, irregularly-shaped uterus consistent in size with a 16-week gestation. Her hemoglobin concentration is 9 g/dL, hematocrit is 30%, and mean corpuscular volume is 92 μm3. Pelvic ultrasound shows multiple intramural masses in an irregularly enlarged uterus. The ovaries appear normal bilaterally. The patient has completed childbearing and would like definitive treatment for her symptoms. Operative treatment is scheduled. Which of the following is the most appropriate next step in management?

• A. Leuprolide (Correct Answer)
• B. Progestin-only contraceptive pills
• C. Tranexamic acid
• D. Levonorgestrel-releasing intrauterine device
• E. Estrogen-progestin contraceptive pills

Gynecologic Surgery Explanation: ***Leuprolide*** - **Leuprolide** is a **GnRH agonist** that creates a hypoestrogenic state, effectively reducing the size of **fibroids** and decreasing blood flow. - Using leuprolide pre-operatively in this patient with **anemia** can improve her **hemoglobin levels**, reduce intraoperative blood loss, and potentially make surgery easier. *Progestin-only contraceptive pills* - While progestins can help with abnormal uterine bleeding, they are generally **less effective** in significantly reducing the size of large **fibroids** like those described. - They may not effectively address the **anemia** or the need for definitive surgical management. *Tranexamic acid* - **Tranexamic acid** is an **antifibrinolytic** that can reduce menstrual blood flow but does not affect the size of **fibroids** or address the underlying cause of heavy bleeding. - It would provide symptomatic relief during menstruation but would not prepare the patient for definitive operative treatment or correct chronic **anemia**. *Levonorgestrel-releasing intrauterine device* - A **levonorgestrel-releasing IUD** is effective at reducing menstrual bleeding by causing endometrial atrophy. - However, it may be difficult to insert or less effective in a significantly enlarged and irregularly-shaped uterus due to multiple large **fibroids**, and it does not reduce fibroid size. *Estrogen-progestin contraceptive pills* - **Estrogen-progestin pills** can regulate menstrual cycles and reduce bleeding but are not typically used to shrink large **fibroids**. - They may not be sufficient for severe bleeding or to prepare for surgery in a patient with significant **anemia** and large fibroids.

Gynecologic Surgery US Medical PG Question 5: A 14-year-old girl presents to the emergency room complaining of abdominal pain. She was watching a movie 3 hours prior to presentation when she developed severe non-radiating right lower quadrant pain. The pain has worsened since it started. She also had non-bloody non-bilious emesis 1 hour ago and continues to feel nauseated. Her temperature is 101°F (38.3°C), blood pressure is 130/90 mmHg, pulse is 110/min, and respirations are 22/min. On exam, she has rebound tenderness at McBurney point and a positive Rovsing sign. She is stabilized with intravenous fluids and pain medication and is taken to the operating room to undergo a laparoscopic appendectomy. While in the operating room, the circulating nurse leads the surgical team in a time out to ensure that introductions are made, the patient’s name and date of birth are correct, antibiotics have been given, and the surgical site is marked appropriately. This process is an example of which of the following human factor engineering elements?

• A. Forcing function
• B. Safety culture
• C. Simplification
• D. Standardization (Correct Answer)
• E. Resilience engineering

Gynecologic Surgery Explanation: ***Standardization*** - The surgical **time-out** is a prime example of **standardization** in healthcare, as it involves a prescribed, uniform procedure followed in every surgery to enhance safety. - It ensures critical safety checks—like patient identification, site marking, and antibiotic administration—are consistently performed, thus reducing variability and the potential for errors. *Forcing function* - A **forcing function** is a design element that makes it impossible to commit an error, such as a specific connector shape that prevents incorrect device attachment. - The time-out, while a critical safeguard, still relies on human compliance and does not physically prevent an error from occurring if the steps are not followed. *Safety culture* - **Safety culture** refers to the shared beliefs, values, and attitudes that employees have about safety within an organization. - While a time-out contributes to a strong safety culture, it is a specific process or tool, not the overarching culture itself. *Simplification* - **Simplification** aims to reduce complexity in a process to minimize cognitive load and potential for error. - The time-out adds a structured step rather than simplifying an existing process; its purpose is to ensure all necessary checks are systematically completed. *Resilience engineering* - **Resilience engineering** focuses on an organization's ability to anticipate, cope with, and recover from failures, maintaining stability in the face of disruptions. - While the time-out promotes safety, it primarily addresses error prevention rather than the broader organizational capacity to adapt and recover from system failures.
