Postgastrectomy phytobezoars--endoscopic diagnosis and treatment.

N A Diettrich, F C Gau

    Summary

    Gastric surgery patients frequently develop bezoars, often missed by barium studies. Endoscopic fragmentation and flushing offer a 100% effective, complication-free resolution for these difficult bezoars.

    Area of Science:

    • Gastroenterology
    • Surgical Outcomes

    Background:

    • Bezoars are masses of undigested material in the gastrointestinal tract.
    • Previous gastric surgery is a significant risk factor for bezoar formation.
    • Diagnosis can be challenging, with conventional imaging often yielding false negatives.

    Purpose of the Study:

    • To evaluate the efficacy and safety of esophagogastroduodenoscopy for bezoar diagnosis and treatment.
    • To assess the incidence and characteristics of bezoars in patients with a history of gastric surgery.

    Main Methods:

    • Retrospective review of 33 patients with 38 bezoars diagnosed since 1975.
    • Analysis of patient demographics, surgical history, presenting symptoms, and diagnostic methods.
    • Evaluation of endoscopic fragmentation and flushing as a treatment modality.

    Main Results:

    • 87.8% of patients had prior gastric surgery, with diagnosis occurring an average of 7.7 years later.
    • Epigastric distress and weight loss were common symptoms.
    • Barium studies showed a high rate of false negatives (75.9%); endoscopic treatment achieved 100% success without complications.

    Conclusions:

    • Esophagogastroduodenoscopy is a highly effective and safe method for diagnosing and treating bezoars, particularly in post-gastric surgery patients.
    • Endoscopic fragmentation and flushing should be considered the primary treatment for bezoars.
    • The high rate of false negatives with barium studies underscores the need for endoscopic evaluation.
