A Problematic Peril of Pessaries: The Rare Case of Rectovaginal Fistulas Resulting From Pessary Use
Bibliographic record
Abstract
Pelvic organ prolapse (POP) is a condition of herniation of the pelvic organs into the vagina or past the introitus. Management options include pessary use. A very rare complication of pessary usage is erosion resulting in a vesicovaginal or rectovaginal fistula. We present two cases of patients who were found to have rectovaginal fistulas from Gellhorn pessary usage. Both patients were surgically treated with colostomies. Pessary management of POP is very common and accepted form of treatment. For optimal outcomes with pessary use, we recommend that patients be actively managed with individualized periodic evaluations. Estrogen cream may be considered for prevention and treatment of eroded vaginal epithelium. J Clin Gynecol Obstet. 2015;4(1):193-196 doi: http://dx.doi.org/10.14740/jcgo308w

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.
