A case report and comprehensive literature review on colorectal seed bezoars caused by Akebia trifoliata seeds

The occurrence of bezoars is a relatively rare medical condition. Seed bezoars are typically discovered in the rectum and can cause symptoms such as constipation and pain. While the ingestion of seeds can lead to rectal impaction, complete intestinal blockage is uncommon. Although bezoars with various seeds have been documented, those containing Akebia trifoliata seeds are rare. A case report describes a patient who developed lower gastrointestinal obstruction following consumption of Akebia trifoliata seeds. The patient was admitted to the hospital due to recurring abdominal pain and difficulty passing stool for 4 days. The Computed Tomography Scan revealed an intestinal obstruction in the lower gastrointestinal tract, which was later confirmed through colonoscopy and patient history as being caused by ingestion of Akebia trifoliata seeds. After receiving treatment, the intestinal tract recovered; however, multiple ulcers persisted.
