Abstract
BACKGROUND: Open restoration of bowel continuity after a Hartmann procedure has been associated with significant morbidity, including anastomotic leak, incisional hernia, wound infections and inability to re-establish intestinal continuity. Few studies have examined the role of laparoscopy in performing a Hartmann reversal. The aim of this study was to review our laparoscopic Hartmann reversal (LHR) experience with an emphasis on intra- and postoperative adverse events. METHODS: A prospectively collected laparoscopic colorectal database involving 3 surgeons in 4 academic centres between 1991 and 2008 was reviewed. Factors evaluated were patient demographics, diagnosis, duration of surgery, intra- and postoperative complications, recovery of bowel function and length of stay in hospital. RESULTS: Twenty-eight consecutive patients (13 men, 15 women) with a mean age of 61.1 (standard deviation [SD] 15.3) years and a mean weight of 72.3 (SD 20.1) kg underwent LHR. The diagnosis at initial surgery was complicated diverticulitis in 19 patients (67.9%), cancer in 6 patients (21.4%) and "other" in 3 patients (10.7%). The median duration of surgery was 166.2 (SD 74.4) minutes. There were no conversions. There was 1 major intraoperative complication (bleeding; 3.6%). There were 3 postoperative complications (10.7%): 1 abscess, 1 prolonged ileus and 1 wound hematoma. Only 1 patient with an abscess required readmission. There were no observed clinical anastomotic leaks. All patients underwent successful reanastomosis. The median time to return of bowel function was 4 (interquartile range [IQR] 3-4) days. The median length of stay in hospital was 5 (IQR 3-6) days. There was no mortality. CONCLUSION: Laparoscopic colostomy reversal after a Hartmann procedure is safe and feasible in experienced hands. It is associated with low morbidity, quick return of bowel function and short stay in hospital.

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 it
