title: Histologic analysis of the hernia sac: current practices based on a survey of IPEG members.
abstract: BACKGROUND
  Inguinal hernia repair is one of the most common operations performed by pediatric surgeons. Although the practice of sending the hernia sac for histologic examination after routine hernia repair is common, the indications and practice patterns for this have not been evaluated. The objective of this survey was to determine practice patterns and indications for histologic analysis of the pediatric inguinal hernia sac.
  
  
  METHODS
  A 9-question online survey was sent to all members of the International Pediatric Endosurgery Group (IPEG). A Kruskal-Wallis test was used to determine whether practice patterns of sending the hernia sac for histologic evaluation were associated with respondent characteristics. The chi-squared test with Yates's correction was used where appropriate.
  
  
  RESULTS
  The survey was completed by 315 IPEG members, for a response rate of 54.4%. Hernia sacs were sent for histologic evaluation always by 23.9%, often by 5.1%, rarely by 17.5%, and never by 53.5%. The respondent characteristics were not associated with whether or not specimens were sent for histology review. Of the 128 who reported sending the inguinal hernia sac, the most common reasons were hospital/state requirements (47.6%), followed by routine practice (25.7%) and concern for missed pathology (24.2%).
  
  
  CONCLUSIONS
  The majority of IPEG respondents report never sending the inguinal hernia sac for histologic analysis. Of those that do, most are influenced by hospital/state requirements. The value of sending the hernia sac after routine inguinal hernia repair should be validated if it is to remain an institutional requirement.
