What do you do with a normal appearing appendix? A national study of Pediatric Surgeons

Abstract

Objectives: Surgeons may encounter a grossly normal appearing appendix in a patient with clinically suspected appendicitis. The purpose of this study is to determine the practice of pediatric surgeons in Saudi Arabia when this is encountered, and determine the reasons behind their decision making.

Methods: An electronic survey was sent to all pediatric surgeons in Saudi Arabia. Data points collected included demographics, peri-operative imaging preference, and personal practice when managing an intra-operative grossly normal appendix in symptomatic children.

Results: A total of 105 responses were obtained yielding a response rate of 33.8% The majority of respondents, 88 (87.1%) would remove the appendix while 13 (12.9%) would leave it in situ. The most common reason for removing the appendix was the possibility of microscopic/Endo appendicitis 71 (34.8%) while the most common reason for leaving the appendix in situ was the possible usage of the appendix for reconstructive benefits in the future 11 (50%). The overwhelming majority 87 (86.1%) felt that there were no sufficient guidelines on removal of the normal appearing appendix at the time of surgery for suspected acute appendicitis.

Conclusion: The majority of pediatric surgeons in Saudi Arabia would proceed with an appendectomy when an intra-operative grossly normal appendix is seen in patients suspected to have acute appendicitis. There is a clear lack of published pediatric guidelines and large studies to guide the correct course of action.
