Surgical evaluation of Henoch-Schönlein purpura. Experience with 110 children
1Department of Surgery, Indiana University School of Medicine, Indianapolis.
Insights
Henoch-Schönlein purpura (HSP) in children often causes abdominal pain and gastrointestinal bleeding. Early diagnosis using clinical and imaging findings can prevent unnecessary surgeries for HSP complications.
Area of Science:
- Pediatrics
- Immunology
- Gastroenterology
Background:
- Henoch-Schönlein purpura (HSP) is an autoimmune vasculitis of unknown etiology.
- It commonly affects children, presenting with a characteristic rash, arthritis, abdominal pain, and kidney disease.
Purpose of the Study:
- To analyze the clinical manifestations and complications of Henoch-Schönlein purpura in a pediatric cohort.
- To evaluate the diagnostic accuracy and necessity of surgical interventions for suspected HSP complications.
Main Methods:
- Retrospective review of 110 children diagnosed with Henoch-Schönlein purpura.
- Analysis of clinical presentations, gastrointestinal symptoms, surgical procedures, and patient outcomes.
- Correlation of diagnostic findings with surgical necessity.
Main Results:
- Abdominal pain was present in 65% of patients, with gastrointestinal bleeding in some.
- 12 patients underwent laparotomy, with 6 unnecessary appendectomies and 1 bowel resection.
- Intussusception occurred in 6 patients, requiring surgery in 3; massive gastric hemorrhage occurred in 2.
- Testicular scintigraphy helped avoid unnecessary scrotal exploration in 4 patients.
Conclusions:
- A high index of suspicion and early diagnosis of HSP are crucial to avoid unnecessary surgical interventions.
- While most cases are managed conservatively, life-threatening complications like hemorrhage, obstruction, and intussusception may necessitate operative management.
- Prompt and accurate diagnosis improves patient outcomes and reduces surgical morbidity.
Abstract:
Henoch-Schönlein purpura is a disorder of unknown origin that is probably related to an autoimmune phenomenon. This report concerns 110 children (mean age, 6.2 years; range, 6 months to 14 years) with Henoch-Schönlein purpura. Seventy-two (65%) had abdominal pain associated with nausea and vomiting, bloody stool, and upper gastrointestinal bleeding. Sixty patients with abdominal pain were evaluated and treated conservatively. However, 12 patients underwent laparotomy. Six underwent unnecessary appendectomy for wrongly diagnosed appendicitis. Bowel resection was performed in one patient for an obstructive ileal lesion. Six additional patients had intussusception; surgery was required in three, while barium enema reduction was successfully accomplished in three others. Massive gastric hemorrhage required ligation, vagotomy, and pyloroplasty in two instances. One child with severe scrotal pain, hemorrhage, and swelling underwent unnecessary scrotal exploration. Four additional patients with similar symptoms avoided operation after a testicular scintiscan demonstrated good blood flow. A high index of suspicion and early diagnosis of Henoch-Schönlein purpura based on clinical, roentgenographic, and laboratory findings may avoid unnecessary operations in most cases. However, life-threatening complications (hemorrhage, obstruction, and intussusception) may occur and require operative intervention. All of the patients survived.
