A Neglected Case of Colonic Tuberculosis With Thoracolumbar Enterocutaneous Fecal Fistulae
Bibliographic record
Abstract
Although intestinal tuberculosis (ITB) typically affects ileocecal segments, the complication of tubercular enterocutaneous fistula is very rare. As an isolated phenomenon, primary intestinal manifestation without extraintestinal tuberculosis (TB) is exceptional and rarely reported. We present a patient with isolated ITB with six spontaneous thoracolumbar tubercular enterocutaneous fistulae. A 37-year-old Chinese woman was admitted to our institution complaining of escape of fecal matter through several openings in her back over the previous 20 years. She had nonspecific abdominal symptoms (occasional abdominal pain and alteration in bowel habit). External physical examination confirmed the presence of external thoracolumbar fecal fistulae in association with a scoliosis. Abdominal examination was unremarkable. Diagnostic colonoscopy with biopsy did not definitively confirm a diagnosis of TB. Microscopic examination in both microbiology and histopathology labs failed to identify acid-fast bacilli; however, gastrointestinal TB (GITB) was considered high on the differential diagnosis list. It was elected to perform open laparotomy with resection of the left hemi-colon. Postoperatively, she was treated with standard anti-tuberculous treatment for 6 months. The patient had an uneventful postoperative course, during which the fistulae gradually closed over the next year. This case with several low-output fistulas exiting the patient's back was successfully treated by a combination of surgery and antimicrobial therapy. The aim of this rare case report is to raise the awareness of atypical presentation of tubercular colonic enterocutaneous fistula so that timely diagnosis and intervention can salvage patient quality of life.

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.
