What is Symphysiotomy?
Symphysiotomy is a surgical procedure with a long and complex history. It involves dividing the cartilage of the pubic symphysis to widen the pelvis, aiding childbirth when there are complications.
-
Definition and Purpose: Symphysiotomy is a surgical method to widen the pelvis by cutting the cartilage of the pubic symphysis, helping in cases of obstructed labor.
-
Historical Background: The first recorded symphysiotomy was described in 1597 by Severin Pineau, who noticed a diastasis of the pubis in a hanged pregnant woman.
-
Evolution of the Procedure: Initially, it involved manually cutting through the pubic symphysis. In the 18th century, John Aitken invented a chainsaw-like device to assist in the procedure.
When is Symphysiotomy Used?
Symphysiotomy is not a common procedure today, but it has specific indications and uses, especially in certain challenging childbirth scenarios.
-
Indications: It is indicated in cases of obstructed labor, particularly when the cervix is fully dilated and the baby's head is at most 2 cm above the ischial spines or no more than 3/5 above the pelvic inlet.
-
Controversial Practices in Ireland: Between 1944 and 1987, symphysiotomies were performed in Ireland without patient consent, often under religious motivations, leading to the formation of the Survivors of Symphysiotomy (SoS) advocacy group in 2002.
Risks and Complications
Like any surgical procedure, symphysiotomy carries risks and potential complications that must be carefully considered.
-
Complications: Risks include urethral and bladder injury, fistulas, infection, pain, and long-term walking difficulty, emphasizing the need for strict medical guidelines.
-
Procedure Details: The procedure involves surgically dividing the ligaments of the symphysis pubis under local anesthesia, often combined with vacuum extraction for safer delivery.
-
Temporary Pelvic Enlargement: Symphysiotomy results in a temporary increase in pelvic diameter, typically up to 2 centimeters, aiding vaginal delivery.
Symphysiotomy vs. Cesarean Section
Comparing symphysiotomy with Cesarean sections helps understand why one might be chosen over the other in certain situations.
-
Comparison with Cesarean Section: While Cesarean sections are preferred for difficult births, symphysiotomy remains a life-saving procedure where Cesarean sections are not feasible or available.
-
No Uterine Scarring: One advantage of symphysiotomy is the absence of uterine scarring, eliminating the risk of future uterine rupture associated with Cesarean sections.
-
Risk of Fistula: Symphysiotomy has a higher risk of fistula formation compared to Cesarean sections, a significant concern in postoperative care.
-
Infection Risk: Despite the higher fistula risk, symphysiotomy has a lower infection risk compared to Cesarean sections, especially in resource-poor settings.
Modern Guidelines and Practices
Current guidelines and practices ensure symphysiotomy is performed safely and only when necessary.
-
Current Practice Guidelines: Symphysiotomy is recommended for trapped head during vaginal delivery of a breech birth, particularly in rural and resource-poor settings of developing countries.
-
Maternal and Perinatal Mortality: A 2016 meta-analysis found no significant difference in maternal and perinatal mortality between symphysiotomy and Cesarean sections in low and middle-income countries.
Historical Context in Ireland
The use of symphysiotomy in Ireland has a controversial history, with many women suffering long-term consequences.
-
Historical Use in Ireland: Symphysiotomies were popular in Ireland well into the 20th century, partly due to religious beliefs and fear of future uterine rupture from multiple Cesarean sections.
-
Patient Experiences: Women who underwent symphysiotomy in Ireland often described it as terrifying, agonizing, and debilitating, with chronic health issues like incontinence, pain, and early arthritis.
-
Compensation for Victims: In 2016, hundreds of Irish women who underwent symphysiotomy were awarded compensation by the government, acknowledging the historical injustices they faced.
-
Advocacy and Awareness: The Survivors of Symphysiotomy (SoS) advocacy group has raised awareness about the procedure and its implications, leading to significant changes in medical practices and patient rights.
Ethical Considerations
The ethical implications of symphysiotomy, especially when performed without consent, are profound.
- Medical Ethics: The forced symphysiotomies in Ireland between 1944 and 1987 raise serious ethical concerns, highlighting the importance of informed consent and ethical medical practices.
Global Perspective
Symphysiotomy's role varies globally, being rare in developed countries but crucial in resource-poor settings.
-
Global Perspective: Symphysiotomy is rarely performed in developed countries due to safer alternatives like Cesarean sections but remains vital in resource-poor settings.
-
Technique Evolution: The technique has evolved, with improved operative methods like partial symphysiotomy and better postoperative care reducing complications.
-
Local Anesthesia: Typically performed under local anesthesia to minimize pain and ensure patient comfort, using lignocaine (0.5% solution) for infiltration.
-
Guidelines for Performance: To ensure safety, symphysiotomy should be performed only when no safe alternative exists and should not be repeated due to risks of gait problems and continual pain.
-
Physical Therapy: Patients with long-term walking difficulties and pain post-symphysiotomy can benefit from physical therapy to improve their condition and reduce discomfort.
-
Abduction of Thighs: Abducting the thighs more than 45 degrees from the midline can cause tearing of the urethra and bladder, highlighting the importance of careful positioning during the procedure.
