BackgroundWound complications following midline laparotomies are common and the main source of postoperative morbidity including superficial or deep wound infection, skin dehiscence, fascia dehiscence, and incisional hernia. Abdominal closure complications are strongly associated with suture technique and material, in addition to other factors related to the patient and type of surgery performed. The traditional technique is to place the fascia sutures 1 cm apart and at least 1 cm away from the fascia edge. A Swedish study described a new technique of placing the sutures 5 mm apart and 5 mm away from the fascia edge, resulting in lower rates of abdominal wound complications. This study has a number of limitations. There is a need for improved quality evidence to convince the surgical community to change the closure technique of abdominal wounds aiming to reduce morbidity, which is exemplified in incisional hernias and other various postop complications.MethodsThis is a 1:1 randomized, controlled, patient- and assessor-blinded, parallel design, superiority trial, with a primary endpoint of incisional hernia at 1 year. The study will be conducted at AUBMC over a 3-year period. Patients planned for a non-emergent midline laparotomy for general surgery or vascular procedure will be randomized to either fascia closure technique. In order to detect a drop of 12% in the incidence of incisional hernia, with 80% power and an alpha of 0.05, we will need to recruit 114 patients per arm. After adjusting for loss to follow-up, target recruitment is 274 subjects. We will compare both arms for the primary, secondary, and exploratory outcomes, using chi-square or t test as appropriate. Univariate and multivariate logistic regression will be done.DiscussionThis trial will assess postop complications following abdominal midline wound closures via two different suturing techniques. This trial will generate evidence-based conclusions that will allow surgeons to assess the role of a new abdominal closure technique in decreasing short- and long-term postoperative complications, for a commonly performed procedure.Trial RegistrationClinicalTrials.gov NCT03527433 .
