Insights
Pediatric noncirrhotic portal hypertension management is debated. This study suggests most children achieve good long-term outcomes with conservative care, avoiding surgery.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Surgical Management
Background:
- Management of noncirrhotic portal hypertension in children lacks consensus.
- Surgical intervention versus conservative approaches are debated.
Purpose of the Study:
- To evaluate long-term outcomes of pediatric noncirrhotic portal hypertension.
- Compare outcomes between surgical and conservative management strategies.
Main Methods:
- Retrospective study of 26 pediatric patients.
- Analysis of platelet counts, WBC counts, spleen size, hospital admissions, and GI bleeds.
- Utilized univariate and time-trend analyses.
Main Results:
- Portal vein thrombosis present in 84.6% of patients.
- No progression of hypersplenism in non-surgical patients; no significant spleen size reduction post-surgery.
- Surgical intervention significantly reduced GI bleeding hospital admissions (P=0.0009).
- Platelet and WBC counts trended downward in medically managed patients; increased/stable in surgical patients.
Conclusions:
- Most pediatric noncirrhotic portal hypertension patients may achieve good long-term outcomes without surgery.
- Findings suggest conservative management can be effective, despite study limitations.
Background/Objectives:
The optimal management of children with noncirrhotic portal hypertension is controversial. Some groups suggest early and aggressive surgical intervention, while others report long-term success with conservative management.
Methods:
We conducted a retrospective study of 26 patients with noncirrhotic portal hypertension treated at our institution. We compared platelet counts, white blood cell (WBC) counts, spleen size, hospital admissions, gastrointestinal bleeds, and longitudinal trends of specific clinical parameters using standard univariate and time-trend analytic techniques.
Results:
Mean age at the time of diagnosis was 5.2 years. Portal vein thrombosis was found in 84.6% of patients (n=22). There was one mortality related to malignancy. There was not a progression of hypersplenism in patients that did not receive a shunt and conversely, we did not notice a significant decrease in spleen size following shunt surgery (P=0.2). Platelet and WBC counts trended downward among patients managed medically, while platelets increased and WBC counts remained stable in surgical patients. There was a significant decrease in hospital admissions for gastrointestinal bleeding following surgical intervention in the shunt group compared with nonshunt (P=0.0009).
Conclusion:
While our analysis was limited given small sample sizes and selection bias, it suggests that the majority of pediatric patients with noncirrhotic portal hypertension will do well long-term without surgical intervention.
