This study is intended to demonstrate the non-inferiority of a Duramesh closure as compared to a polydioxanone closure for early surgical site events (SSE) (< 1 month), and Duramesh superiority to polydioxanone for the development of incisional hernia by 1 year for a laparotomy closure.
This clinical investigation is designed to compare laparotomy closure with Duramesh to closure using PDS. The primary outcome is SSE that occurs within 1 month after surgery. Secondary outcomes that will be studied include device performance and technical success of the index-procedure, hernia occurrence/recurrence noted at 12 months after surgery, SSE and re-interventions that occur within 12 months of surgery, pain, implant palpability/sensation, surgeon and patient satisfaction, and quality of life.

| Duramesh | Other | Laparotomy closure is associated with the occurrence of Surgical Site Events (SSEs) such as wound dehiscence and incisional hernias. Abdominal wall closure can also cause pain and discomfort, or can lead to intestinal obstruction. Standard sutures can cut through otherwise intact tissue due to the presence of a sharp leading edge leading to repair failure. Meshes distribute forces and allow for tissue ingrowth. Duramesh combines the desirable principles of a mesh repair with the placement precision of a suture. It is the world's first device that both approximates tissue and allows ingrowth for a strong early repair. Consequently, the expected clinical benefit is the reduced occurrence of Surgical Site Events such as incisional hernias. Additional benefits may include reduced pain and improved quality of life due to durable closure of the abdominal wall with Duramesh. This will be evaluated in this randomized study. Size 1 Duramesh is used in this RCT. Duramesh is CE-marked. |

| Clinical hernia occurrence/recurrence within 12 months after repair. | This study is intended to demonstrate Duramesh superiority to polydioxanone for the development of incisional hernia by 1 year for a laparotomy closure. | 12 months |
| Return to the operating room (re-interventions) within 12 months for device related issue. | Re-interventions are defined as: All re-interventions relating to abdominal wall closure complications or abdominal re-exploration. | 12 months |
| Surgeon satisfaction at index-procedure using the 5-point smiley face scale. | Procedure |
| Surgeon satisfaction at 1-month follow-up using the 5-point smiley face scale. | 1 month |
| Technical success of index-procedure. | Technical success is defined as successful abdominal wall closure without unexpected difficulties. | Procedure |
| Device performance using the 5-point smiley face scale. | Procedure |
| Pain of the surgical incision using 11 point Numeric Pain Rating Scale (NRS) at 1-month follow-up. | The pain NRS is a single 11-point numeric scale with 0 representing one pain extreme (e.g., "no pain") and 10 representing the other pain extreme (e.g., "pain as bad as you can imagine" and "worst pain imaginable"). The NRS is a segmented numeric version of the visual analog scale (VAS) in which a respondents selects a whole number (0 to 10 integers) that best reflects the intensity of their pain. Pain will be scored in rest and with activity. Activity is defined as activity of daily living, e.g. walking, driving, getting into a car, setting the dinner table, doing the laundry, etc. | 1 month |
