Is routine pathological evaluation of pediatric hernia sacs justified?

Area of Science:

• Pediatric Surgery
• Surgical Pathology
• Cost-Effectiveness Analysis

Background:

• Herniorrhaphy is a common pediatric surgical procedure.
• Pathological examination of hernia sacs is often recommended to detect vas deferens ligation.
• The necessity of routine pathological examination is questioned due to low incidence of injury.

Purpose of the Study:

• To determine the actual incidence of unrecognized vas deferens or epididymis ligation during pediatric herniorrhaphy.
• To assess the clinical utility of routine pathological examination of pediatric hernia sacs.
• To evaluate the cost-effectiveness of current recommendations for hernia sac examination.

Main Methods:

• Retrospective review of pathology reports for pediatric inguinal hernia repairs over a 3-year period (1994-1996).
• Analysis of 1,494 inguinal hernia sacs from 1,077 pediatric patients.
• Classification of findings into incidental and positive (vas deferens identification).

Main Results:

• The incidence of vas deferens injury during herniorrhaphy was 0.13% (2 of 1,494).
• All identified vas deferens injuries were recognized by surgeons intraoperatively.
• No occult carcinomas or other significant pathologies altering clinical management were found.

Conclusions:

• Routine pathological examination of pediatric hernia sacs may not be warranted given the low incidence of injury and lack of significant incidental findings.
• Selective pathological examination when vas deferens injury is suspected is recommended.
• Eliminating routine examination could lead to substantial cost savings in healthcare settings.
