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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
