Abstract
Aim: To analyze laparotomy closure of conventional midline and transverse abdominal incisions in elective and emergency laparotomies with a longterm, absorbent, elastic suture material. Method: Prospective, single centre, non randomised, controlled cohort study on short stitches with a longterm resorbable, elastic suture (material: poly-4-hydroxybutyrate) aiming at a 6:1 suture to wound (SL/WL) length ratio in midline and transverse, primary & secondary laparotomies for elective & emergency surgery. Results: We included 351 patients (♂: 208; ♀: 143), midline (n=194), transverse (n=103) and a combined midline/transverse L-shaped (n=54) incisions. There was no stitch performance quality difference between elective (n=296) and emergency (n=55) operations, while results in the first 150 patients showed a significantly reduced SL/WL-ratio to the following 200 suture closures (SL/WLratio: 5.64±2.5 vs 6.1±2.3, p<0.001). Average SL/WL-ratio in general was better for midline than transverse incision sutures (6.62±2.5 vs 4.3±1.51, p<0.001). SL/WL-ratio varied among the 6 surgeons participating, although results steadily improved and eventually approximated each other. Conclusions: We could show that a 6:1 SL/WL-ratio with a 2-0 single, ultra-long term, absorbent, elastic suture material can be significantly performed better in midline than transverse incisions. Transverse incisions should preferably be closed in 2 layers in order to achieve a sufficient SL/WL-ratio equivalent to the median incision. While on an individual level, results varied between surgeons, quality will improve and eventually approximate.
