Case report: Tenesmus and the role of superior hypogastric plexus blocks
Bibliographic record
Abstract
Background: Tenesmus is the unpleasant sensation of incomplete emptying of the rectum and it may be a distressing symptom for patients who suffer from rectal masses. Unlike nociceptive pain or visceral pain, little is understood about the pathway for this pain phenotype. There are also few studies examining the palliative treatment of this symptom. Case Presentation: In this case report, we describe a patient who presented with severe and refractory tenesmus secondary to a metastatic rectal lesion. Case Management: To address the patient’s refractory tenesmus, a superior hypogastric plexus neurolytic block was performed with alcohol under fluoroscopic guidance. Case Outcome: Immediately after the procedure, the patient reported complete abolishment of her tenesmus symptom. This effect endured for 3 months after which the patient. Conclusion: Superior hypogastric plexus block may be an effective procedure for the management of tenesmus. The successful abolishment of tenesmus following the block alludes that the nerve fibers carrying sensation of tenesmus either synapses or passes through the superior hypogastric plexus. Future studies should consider examining the neural pathway of tenesmus.

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.
