Argon Plasma Coagulation of Hemorrhagic Solitary Rectal Ulcer Syndrome
Bibliographic record
Abstract
Solitary ulcer syndrome (SUS) is a rare disorder that may provoke hematochezia. Argon plasma coagulation (APC) is used in a wide range of gastrointestinal bleeding. We experienced APC in a patient with a bleeding gigantic SUS: a 64-year-old woman who developed a SUS at 60. After 3 years, recurrent hematochezia, secondary anemia, and rectal pain occurred. Endoscopy revealed a large rectal bleeding ulcer. Moreover, the pain led the patient to assume analgesics. These conditions stimulated us to treat this ulcer with APC within 4 sessions; each session spaced out at 30-day intervals. The patient experienced and maintained the following benefits: (1) resolution of bleeding and secondary anemia after the first session, (2) reduction of ulcer depth, disappearance of pain and analgesic withdrawal at the end of the cycle, (3) almost complete endoscopic healing of the ulcer after 9 months of follow-up. This experience suggests that APC may represent a therapeutic approach for bleeding SUS even if controlled studies are necessary before recommending it as acceptable treatment.

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.
