What is the Fowler's operation?

3 min read

It is a common misconception that there is only one surgical procedure referred to as "Fowler's operation"; in reality, the name is associated with several distinct medical procedures and a specific patient position. The most prominent surgical application is the Fowler-Stephens orchiopexy, used to correct undescended testicles in infants and children.

Quick Summary

The term 'Fowler's operation' is ambiguous and refers to several different surgical techniques, including the Fowler-Stephens orchiopexy for undescended testes, Fowler tenotomy for mallet finger, and the Fowler-Weir approach for appendectomy. It is often confused with Fowler's patient positioning.

Key Points

  • Diverse Procedures: The term "Fowler's operation" refers to several distinct medical and surgical techniques, including pediatric urology and hand surgery.

  • Fowler-Stephens Orchiopexy (FSO): This surgery corrects high, undescended testes by dividing testicular vessels and using collateral blood supply.

  • One-Stage vs. Two-Stage FSO: FSO can be done in one or two stages, with the two-stage process often showing higher success for very high testes.

  • Fowler Tenotomy: An orthopedic surgery to correct chronic mallet finger deformity by detaching an extensor tendon slip.

  • Not a Patient Position: These operations are different from Fowler's position, a patient care technique for elevating the head of the bed.

The name "Fowler's" is most famously linked to George Ryerson Fowler, a 19th-century surgeon who pioneered various techniques. His legacy includes multiple procedures, though the specific "operation" most often referenced is related to pediatric urology.

The Fowler-Stephens Orchiopexy (FSO)

This is the most common surgical procedure known as a Fowler's operation. The FSO is specifically performed on infants and children with a condition called cryptorchidism, or undescended testes, particularly when the testicle is located high within the abdomen. The procedure's necessity arises when the spermatic vessels are too short to allow the testicle to be moved into the scrotum normally. The FSO relies on preserving the collateral blood supply from the vas deferens while the main testicular artery is divided, allowing the testicle to be mobilized and placed in the scrotum.

One-Stage versus Two-Stage FSO

  • One-Stage Procedure: The testicular vessels are divided, and the testicle is immediately moved and secured in the scrotum. This can often be done laparoscopically.
  • Two-Stage Procedure: This involves two surgeries. In the first stage, the testicular vessels are tied off, allowing time for collateral vessels to grow. The second stage, several months later, involves bringing the testicle down into the scrotum. This approach is often associated with higher success and lower testicular atrophy rates for high intra-abdominal testes.

The Fowler Tenotomy

Another procedure named after Fowler is the tenotomy, an orthopedic surgery for chronic mallet finger, which can cause a swan-neck deformity. The procedure involves detaching the central slip of the extensor tendon to correct hyperextension of the middle joint and improve fingertip extension.

The Fowler-Weir Approach

The Fowler-Weir approach is an incision technique used in appendectomy that spares muscle. Research indicates it may lead to lower infection rates compared to other methods.

Distinguishing from Fowler's Position

It is important to differentiate these surgeries from Fowler's position. Also named after George Ryerson Fowler, this is a patient positioning technique, not a surgery, where the head of the bed is raised 45-60 degrees.

Comparison of Fowler-named Medical Interventions

Feature Fowler-Stephens Orchiopexy (FSO) Fowler Tenotomy Fowler-Weir Approach Fowler's Position
Purpose To bring a high, undescended testicle into the scrotum To correct chronic mallet finger and associated swan-neck deformity To provide surgical access for an appendectomy To aid breathing, drainage, and promote patient comfort
Target Condition High cryptorchidism (undescended testes) Chronic mallet finger, swan-neck deformity Appendicitis Respiratory distress, post-abdominal surgery recovery
Body Part Testicle Finger Abdominal cavity Entire body
Intervention Type Laparoscopic or open surgery Orthopedic surgery (tenotomy) Incisional technique for abdominal surgery Patient positioning (not a surgery)
Method Division of testicular vessels, relying on collateral supply Detachment of central extensor slip of the tendon Muscle-sparing incision Elevating the head of the bed to 45-60 degrees

Conclusion

The term Fowler's operation is not singular but refers to several distinct procedures and a patient position. The Fowler-Stephens orchiopexy is a key procedure for undescended testes, available in one or two stages. Other uses include Fowler tenotomy for finger deformities and the Fowler-Weir approach for appendectomy. These are distinct from Fowler's position, a non-surgical patient positioning method. Always consult a medical professional for health concerns. More information on cryptorchidism treatment is available from the {Link: NIH website https://pubmed.ncbi.nlm.nih.gov/23690511/}.

Frequently Asked Questions

The primary purpose is to surgically move a high, undescended testicle (cryptorchidism) into the scrotum.

The two-stage procedure allows time for collateral blood vessels to develop, potentially reducing the risk of testicular atrophy for very high abdominal testicles.

Fowler's operation refers to surgical procedures, while Fowler's position is a patient care technique where the patient is placed in a semi-sitting position.

Success rates vary, but the two-stage approach for high testes often shows success rates around 85-89%, with lower atrophy compared to single-stage.

It is a specific orthopedic technique for chronic mallet finger deformities, less widely known than the orchiopexy.

Standard orchiopexy moves the testicle without dividing vessels. The Fowler-Stephens is used when vessels are too short, requiring their division to mobilize a high testicle.

Risks for FSO include testicular atrophy and malpositioning. For tenotomy, risks include extensor lag.
