Insights
Appendicoliths, calcified deposits in the appendix, significantly increase the risk of complicated appendicitis in children, leading to higher perforation and abscess rates. Intraoperative detection is crucial for managing these cases effectively.
Area of Science:
- Pediatric Surgery
- Diagnostic Imaging
- Gastrointestinal Health
Background:
- Appendicoliths are calcified deposits within the appendix, frequently causing complicated appendicitis in pediatric patients.
- Their presence correlates with increased risks of appendicular perforation, abscess formation, and necessitates urgent surgical intervention.
- Accurate preoperative and intraoperative detection of appendicoliths is vital for guiding surgical decisions and improving patient outcomes.
Purpose of the Study:
- To assess the diagnostic accuracy of imaging modalities for appendicoliths in children with acute appendicitis.
- To evaluate the surgical management strategies employed for appendicitis associated with appendicoliths.
- To analyze the postoperative outcomes in pediatric patients with appendicoliths.
Main Methods:
- A retrospective chart review was conducted on 198 pediatric patients (<18 years) who underwent appendectomy.
- Data collected included demographics, ultrasonography (USG) and CT imaging findings, intraoperative observations, and postoperative results.
- Comparison was made between patients with and without appendicoliths to identify associated complications and outcomes.
Main Results:
- Appendicoliths were identified in 15.2% preoperatively via USG and 44.9% intraoperatively.
- Children with appendicoliths showed significantly higher rates of perforation (74.2% vs. 14.7%) and abscess formation (91% vs. 17.4%).
- Postoperative wound infection rates were also higher in children with appendicoliths (33.7% vs. 9.2%). Laparoscopic appendectomy was effective with a 6.1% conversion rate.
Conclusions:
- Appendicoliths are a significant risk factor for complicated appendicitis in children.
- Ultrasonography has limited sensitivity for detecting appendicoliths; intraoperative identification is associated with more complications.
- Laparoscopic appendectomy is a safe and effective treatment for appendicitis involving appendicoliths.
Abstract:
Background and objective Appendicoliths are calcified deposits within the appendix and are often the cause of complicated appendicitis in children. Their presence is associated with appendicular perforation, abscess formation, and the need for immediate surgical intervention. Preoperative and intraoperative detection influence surgical decision-making and outcomes. This study aimed to evaluate the diagnostic accuracy of imaging, surgical management, and postoperative outcomes associated with appendicoliths in children with acute appendicitis. Methods We conducted a retrospective chart review of 198 children aged <18 years who were admitted to the Department of Pediatric Surgery and underwent appendectomy. The data included demographics, imaging findings on ultrasonography (USG) and CT, intraoperative findings, and postoperative outcomes. Results A total of 198 children were enrolled in this study. Laparoscopic appendectomy (LA) was performed in 83.3% (165) of the patients, with a laparoscopic-to-open conversion rate of 6.1% (12). Appendicoliths were identified in 15.2% (n=30) of cases on preoperative USG and in 44.9% (n=89) intraoperatively. In a comparison between children with appendicoliths (n=89) and those without (n=109), the presence of appendicoliths was significantly associated with higher rates of perforation (74.2% vs. 14.7%, p<0.001), abscess formation (91% vs. 17.4%, p=0.001), and postoperative wound infection (33.7% vs. 9.2%, p=0.001). Conclusions Appendicoliths significantly predispose children to complicated appendicitis. The sensitivity of USG in identifying appendicoliths is limited, and intraoperative detection is associated with a higher incidence of complications than preoperative detection. LA is an effective and safe management option.
