Overview
Postgastrectomy phytobezoars are concretions of indigestible plant material that form in the stomach or proximal small intestine following gastric surgery, often due to altered gastric motility and reduced acid secretion 1. These bezoars can cause significant gastrointestinal obstruction and require intervention 1.Diagnosis
Clinical Presentation: Abdominal pain, nausea, vomiting, and signs of bowel obstruction 1.
Imaging: Abdominal X-ray showing a characteristic bezoar shadow or CT scan revealing a mass in the stomach or small bowel 1.
Endoscopy: Visualization of the bezoar and assessment of the extent of obstruction 1.
Laboratory Tests: Elevated inflammatory markers may be present but are non-specific 1.Management
Endoscopic Removal: First-line treatment using techniques such as polypectomy snares, Roth nets, or retrieval baskets 1.
Surgical Intervention: Indicated for cases where endoscopic removal fails or there is significant obstruction 1.
Dietary Modifications: Advising patients to avoid high-fiber foods and consume easily digestible meals post-gastrectomy 1.Special Populations
No Specific Data: The provided abstracts do not cover special populations such as pregnancy, pediatrics, elderly, or specific comorbidities 1.Key Recommendations
Endoscopic Removal as First-Line: Prioritize endoscopic techniques for the removal of postgastrectomy phytobezoars due to lower morbidity compared to surgery (Evidence: Moderate 1).
Surgical Intervention for Complications: Proceed to surgical intervention if endoscopic removal is unsuccessful or if there is severe obstruction (Evidence: Moderate 1).
Post-Operative Dietary Guidance: Recommend dietary modifications to prevent recurrence, focusing on low-fiber, easily digestible foods (Evidence: Expert opinion 1).References
