Trans-anal minimally invasive surgery
Bibliographic record
Abstract
INTRODUCTION: Transanal minimally invasive surgery (TAMIS) is a valuable surgical option for removal of rectal polyps and early rectal cancers. A potential complication of this technique is abdominal entry if the lesion is located above the peritoneal reflection. We present the first case series describing the use of a laparoscopic stapling device to remove a sessile lesion, and seal the resulting defect simultaneously with full thickness excision of the rectal lesion, avoiding abdominal entry. PRESENTATION OF CASES: Five patients with rectal lesions between 8 and 14 cm from the anal verge are described in this case series. Each underwent a stapled-TAMIS procedure as the lesion was suspected to be above the peritoneal reflection. The goal specimen was achieved in each procedure. DISCUSSION: This article demonstrates the feasibility of a novel technique to remove sessile polyps in the upper rectum using laparoscopic staplers trans-anally through the TAMIS port. More studies and long-term follow-up are needed to evaluate the oncologic outcomes including the recurrence rate for those lesions removed with a stapler. CONCLUSION: For rectal lesions suspected to be above the peritoneal reflection, a stapled resection through a TAMIS port could prove be a valuable addition to the standard excisional approach to TAMIS.

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.
