Rare Case of Sigmoid-Perianal Fistula due to Sigmoid Diverticular Disease: Report of a Case and Review of Literature
Bibliographic record
Abstract
Diverticular disease of colon is a common problem of western countries and its incidence usually increases with age. The natural history of diverticular disease is usually benign with only few patients developing episode of acute diverticulitis. Some patients may develop more complicated courses like hemorrhage, obstruction, stricture or fistulas. While colovesical and colovaginal fistulas are the common types of fistula, perianal fistula due to diverticular disease is an extremely rare complication of diverticular disease. We report a case of sigmoid-perianal fistula due to diverticular disease in a 53-year-old female patient without any signs or symptoms of sigmoid diverticulitis. Diagnosis was established in early course of disease by computed tomogram (CT) scan and a one-stage anterior resection was performed without any complication. We also performed literature review for similar cases and how they were managed. J Med Cases. 2015;6(3):122-124 doi: http://dx.doi.org/10.14740/jmc2065w

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.
