Predictive Factors of Liver Hydatid Cyst Recurrence in Children

Infographic · Oct 2023 · 1 min read

In brief

Retrospective study of 122 children identifies key predictors of liver hydatid cyst recurrence after surgery, including intimate contact with large vessels and intraperitoneal effusion. The 16.4% recurrence rate and identification of modifiable risk factors provide actionable insights for surgeons to implement preventive strategies in endemic regions.

Liver hydatid cyst recurrence occurred in 16.4% of pediatric cases, with median recurrence time of 16.5 months postoperatively
Cyst contact with large vessels and intraperitoneal effusion are independent risk factors for recurrence requiring heightened surveillance
Bile duct dilation at presentation predicts higher recurrence risk and should guide surgical planning and follow-up protocols
Spontaneous discontinuation of postoperative medical treatment significantly increases recurrence risk (p=0.010)
Abdominal ultrasonography is effective for detecting recurrence and should be used for routine postoperative monitoring

Background

Liver hydatid cyst affects approximately 95% of the world's echinococcosis cases. Despite advances in treatment, the recurrence rate remains high and is influenced by several factors that are yet to be determined. The objective of this study was to identify the predictive factors of liver hydatid cyst recurrence following surgery in children and to establish a treatment regimen aimed at preventing this postoperative morbidity.

Methods

A bi-centric retrospective descriptive and analytic study was conducted involving 122 children who underwent surgery for liver hydatid cysts between January 1st, 2009, and December 31st, 2017. All factors that could potentially contribute to recurrence were thoroughly investigated. The data was processed using SPSS.v21, and a significant level of p-value 0.05 was applied.

Results

Out of the 122 children, 20 patients experienced cyst recurrence (16.39%). Among them, there were nine girls and eleven boys. The median time of recurrence was 16.5 months. Abdominal ultrasonography demonstrated efficacy in detecting recurrence. Several factors were identified as predictors of postoperative recurrence, including intimate contact of the hydatid cyst with the large vessels (p = 0.031), intraperitoneal effusion (p = 0.042), bile duct dilation (p = 0.032), and postoperative spontaneous discontinuation of medical treatment (p = 0.010). Among these factors, two independent risk factors for recurrence were identified: intimate contact of the hydatid cyst with the large vessels (p = 0.011) and the presence of an intraperitoneal effusion (p = 0.018).

Conclusion

Our study has identified several predictors of postoperative recurrence, including two previously undocumented risk factors in the literature. Awareness of these risk factors can assist surgeons in implementing preventive measures to avoid the recurrence of hydatid cysts.
