Clinical Performance and Safety of Suture-TOOL


The goal of this single arm intervention study is to investigate the safety and performance of a suturing device for closure of the midline incision after open abdominal surgery. The study population consists of 38 patients selected for open abdominal procedures for malignant and benign colorectal disease. The main question it aims to answer is: • If the device facilitates a Suture-Length to Wound-Length (SL/WL) ratio of 4:1 Participants laparotomy wound will be closed with the device at the end of the operation and closure related data as closure time and SL/WL ratio will be calculated. The wound will be assessed for infection during the postoperative stay and the chart will be reviewed for wound dehiscence and wound infection.

Arms, Groups and Cohorts

  • Experimental: Single arm
    • Closure of the abdomen after laparotomy with Suture-TOOL.

Clinical Trial Outcome Measures

Primary Measures

  • Proportion of patients with Suture length/Wound length (SL/WL) ratio ≥ 4
    • Time Frame: Measured during laparotomy closure.
    • SL/WL-ratio of patients laparotomy closures will be calculated by measuring (centimeter) and dividing the length of used suture with the length of the laparotomy wound.

Secondary Measures

  • Stitch count
    • Time Frame: Measured during laparotomy closure
    • Number of stitches used for laparotomy closure
  • Numbers of sutures used
    • Time Frame: Counted during laparotomy closure
  • Incision closure time
    • Time Frame: Measured during laparotomy closure
    • Time (seconds) from first to last knot during laparotomy closure
  • Surgeons´ comfort with device during closure
    • Time Frame: After laparotomy closure
    • VAS assessment
  • Surgeons´ satisfaction with final closure result
    • Time Frame: After laparotomy closure
    • VAS assessment
