Abstract
A midline specimen extraction incision is most commonly used in laparoscopic colectomy but has a high incidence of incisional hernia (IH). IH may be lower for transverse incision. The objective of this trial was to compare the incidence of IH between midline and transverse specimen extraction site in patients undergoing laparoscopic colectomy. A single-centre parallel-arm non-blinded superiority trial was conducted. Eligible patients undergoing laparoscopic colectomy were randomly assigned to midline or transverse specimen extraction site. The main outcome measure was incidence of IH at 1 year. The power calculation required 76 patients per group to detect a reduction in IH from 20% to 5%. Secondary outcomes included perioperative outcomes, postoperative pain scores and quality of life (SF-36) and cosmesis (Body Image Questionnaire) at 1 year. A total of 165 patients were randomly assigned to transverse (n = 79) or midline (n = 86) specimen extraction site, of which 141 completed 1-year follow-up (68 transverse, 73 midline). Patient, tumour, surgical data and perioperative morbidity were similar. Pain scores were similar on each postoperative day. On intention-to-treat analysis, there was no difference in the incidence of IH at 1 year (transverse 2% v. midline 8%, p = 0.065) or after a mean 30.3 months (SD 9.4) of follow-up (6% v. 14%, p = 0.121). In per-protocol analysis there were more IH in the midline group after longer follow-up (15% v. 2%, p = 0.013). Quality of life was similar between the 2 groups, but cosmesis was better for patients undergoing midline incision v. 17 , p = 0.016). A transverse specimen extraction site has a lower incidence of IH compared with midline with longer follow-up but has worse cosmesis.

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.
