Shiitake mushroom bezoar: a rare cause of small bowel obstruction in Vietnam and lessons in diagnosis and management
Bibliographic record
Abstract
Small Bowel Obstruction (SBO) caused by shiitake mushroom bezoars is a rare clinical entity, with no prior cases documented in Vietnam despite the frequent consumption of these mushrooms in traditional dishes. We report the case of a 69-year-old male who presented with SBO symptoms after ingesting a whole shiitake mushroom without chewing due to significant molar tooth loss. Computed Tomography (CT) imaging revealed characteristic features of a bezoar, and exploratory laparoscopy confirmed an obstructing shiitake mushroom bezoar, which was removed via enterotomy. This case highlights the diagnostic challenges of radiolucent bezoars and the critical importance of dietary history and characteristic CT findings. Preoperative assessments could facilitate less invasive surgical strategies, reducing the risks associated with enterotomy, such as anastomotic leakage. Clinicians should remain aware of regional dietary practices to enhance diagnostic precision and optimize management strategies, especially in highrisk populations with compromised mastication.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
