Clinical observations on the treatment of prolapsing hemorrhoids with tissue selecting therapy
Bibliographic record
Abstract
AIM: To compare the effects and postoperative complications between tissue selecting therapy stapler (TST) and Milligan-Morgan hemorrhoidectomy (M-M). METHODS: Four hundred and eighty patients with severe prolapsing hemorrhoids, who were admitted to the Shenyang Coloproctology Hospital between 2009 and 2012, were randomly divided into observation (n=240) and control (n=240) groups. Hemorrhoidectomies were performed with TST in the observation group and with the M-M technique in the control group. The therapeutic effects, operation security, and postoperative complications in the two groups were compared. The immediate and long-term complications were assessed according to corresponding criteria. Pain was assessed on a visual analogue scale. The efficacy was assessed by specialized criteria. The follow-up was conducted one year after the operation. RESULTS: The total effective rates of the observation and control groups were 99.5% (217/218) and 98.6% (218/221) respectively; the difference was not statistically significant (P=0.322). Their were significant differences between observation and control groups in intraoperative blood loss (5.07±1.14 vs 2.45±0.57, P=0.000), pain (12 h after the surgery: 5.08±1.62 vs 7.19±2.01, P=0.000; at first dressing change: 2.64±0.87 vs 4.34±1.15, P=0.000; first defecation: 3.91±1.47 vs 5.63±1.98, P=0.001), urine retention (n=22 vs n=47, P=0.001), anal pendant expansion after the surgery (2.35±0.56 vs 5.16±1.42, P=0.000), operation time (18.3±5.6 min vs 29.5±8.2 min, P=0.000), and the length of hospital stay (5.3±0.6 d vs 11.4±1.8 d, P=0.000). Moreover TST showed significant reductions compared to M-M in the rates of long-term complications such as fecal incontinence (n=3 vs n=16, P=0.003), difficult bowel movement (n=1 vs n=9, P=0.011), intractable pain (n=2 vs n=12, P=0.007), and anal discharge (n=3 vs n=23, P=0.000). CONCLUSION: TST for severe prolapsing hemorrhoids is a satisfactory technique for more rapid recovery, lower complication rates, and higher operation security.

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.
