Meckel's Diverticulum and Bezoar Impaction: A Potential Cause of Intestinal Obstruction in Adults and Children with Identifiable Risk Factors (Code-T0175)

Introduction: Meckel’s diverticulum is a congenital abnormality that can lead to various complications, including intestinal obstruction. Among the potential causes of obstruction in such cases, bezoars—particularly phytobezoars—are noteworthy, as they can impinge on the bowel. In adults, those following a predominantly vegetarian diet may be at an increased risk of phytobezoar formation, while children with certain psychological conditions, such as trichotillomania or trichotillophagia, may develop trichobezoars. This study explores the association between Meckel’s diverticulum and bezoar impaction, with an emphasis on the role of diet and psychological factors in obstruction cases.

Aims and Objectives: The objective of this study is to investigate the potential link between Meckel’s diverticulum, intestinal obstruction, and bezoar impaction, particularly phytobezoars and trichobezoars, in both adults and children. We aim to highlight diagnostic considerations and treatment options in such cases.

Methods: A retrospective review was conducted on patients diagnosed with Meckel’s diverticulum who presented with bowel obstruction. Data on the types of bezoars, patient demographics, diet history, and psychological conditions were collected. Management strategies and outcomes were also analyzed.

Results: Of the 30 patients studied, 10 had bezoars (7 phytobezoars in adults, 3 trichobezoars in children). Most adult cases had a vegetarian diet, while children had psychological conditions such as trichotillomania. No recurrence of bezoar-induced obstruction was noted during follow-up.

Conclusion: Meckel’s diverticulum may lead to bowel obstruction, and bezoars—especially phytobezoars and trichobezoars—should be considered in differential diagnoses. Awareness of dietary habits and psychological conditions is crucial in managing these cases.
