A Very Rare Cause of Splenic Injury: Splenic Hematoma Following a Diagnostic Upper Endoscopy (Esophagogastroduodenoscopy) and Biopsy of Gastric Ulcer
Bibliographic record
Abstract
The potential for splenic injury from esophagogastroduodenoscopy (EGD) is exceptionally low. To our knowledge, less than five cases have been reported in literature. Though still uncommon, splenic rupture due to diagnostic or therapeutic procedures is more frequently described following colonoscopy and endoscopic retrograde cholangiopancreatography. We report a 62-year-old Caucasian male with primary squamous cell carcinoma of the lung who presented 2 days after an EGD and gastric ulcer biopsy. The patient complained of severe left upper quadrant abdominal pain with rebound tenderness. Upon further evaluation, a diagnosis of a large subcapsular splenic hematoma was made with computed tomography (CT) imaging. The mechanism of splenic injury attributable to EGD is traction on the greater curvature of the stomach, causing avulsion of the splenic or short gastric vessels. We feel this case represents a very rare yet serious complication of EGD that warrants consideration and further investigation.

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.
