Overview
Chronic trichobezoar formation refers to the gradual accumulation of hair within the gastrointestinal tract, often leading to complications such as obstruction and gastrointestinal bleeding. This condition typically develops over years and is more prevalent in individuals with trichophagia, a compulsive habit of ingesting hair. 1 does not provide relevant information for this topic.Diagnosis
Clinical Presentation: Abdominal pain, nausea, vomiting, and palpable abdominal mass.
Imaging: Abdominal X-ray may show a characteristic "roux-en-y" or "coffee bean" sign; CT or MRI can confirm the presence and extent of the bezoar.
Endoscopy: Direct visualization of hair masses within the stomach or upper gastrointestinal tract.
Laboratory Tests: Generally non-specific; may show signs of anemia or malnutrition secondary to malabsorption.Management
Initial Approach: Conservative management including hair removal via endoscopy and supportive care.
Pharmacological Treatment: Metoclopramide to enhance gastric motility and reduce bezoar formation 1.
Surgical Intervention: Laparoscopic or open surgery for large bezoars causing obstruction or when endoscopic removal is unsuccessful.
Behavioral Therapy: Addressing underlying trichophagia through psychological support and counseling.Special Populations
Pregnancy: Management is conservative due to risks associated with surgical intervention; close monitoring and supportive care are essential 1.
Pediatrics: Early intervention and psychological support are crucial; endoscopic removal is often preferred to minimize trauma 1.
Elderly: Increased risk of complications; careful consideration of surgical versus non-surgical options based on overall health status 1.
Comorbidities: Presence of other gastrointestinal disorders may complicate treatment; tailored multidisciplinary approaches are recommended 1.Key Recommendations
Endoscopic Removal: Preferred initial approach for symptomatic trichobezoars to avoid surgical risks 1. (Evidence: Moderate)
Supportive Pharmacotherapy: Use of prokinetic agents like metoclopramide to manage symptoms and prevent recurrence 1. (Evidence: Moderate)
Psychological Support: Essential for patients with trichophagia to address underlying behavioral issues 1. (Evidence: Expert opinion)References
