Outcome Measures

Primary Outcomes (1)

  • To determine the efficacy of mesh reinforcement in laparotomy closure in renal transplantation measured by radiological diagnosis (CT)

    To determine the efficacy of mesh reinforcement in laparotomy closure in renal transplantation measured by radiological diagnosis (CT) of incisional hernia at 2 years post-transplantation.

    24 months

Secondary Outcomes (1)

  • To determine the safety of mesh reinforcement in laparotomy closure in renal transplantation

    3, 6, 12 and 24 months

Other Outcomes (2)

  • To determine the efficacy of mesh reinforcement in laparotomy closure in renal transplantation as measured by the reduction in the incidence of incisional hernia at 2 years post-transplantation measured by radiological diagnosis (CT)

    24 months

  • To determine the incidence of incisional hernia surgery in post-renal transplantation measured by physical examination at 3, 6 and 12 months and by radiological diagnosis (CT) at 24 months

    3, 6, 12 and 24 months

Study Arms (2)

ProGrip® Mesh reinforcement

ACTIVE COMPARATOR

Once the closure has been completed in 2 muscle-aponeurotic planes with continuous synthetic suture (Monomax® USP 0), the closure will be completed by placing the ProGrip® macroporous polypropylene monofilament mesh in supra-aponeurotic position using the surface with the polylactic acid microgrips, which act as Velcro, in direct contact with the superficial aponeurotic plane constituted by the aponeuroses of the greater oblique muscle and the crescentic line of the anterior rectus abdominis muscle. The polylactic acid microgrips provide immediate fixation, making additional fixation with stitches unnecessary, which makes the technique very easy to use and systematize among the different surgeons of the transplant team. The procedure is completed with the placement of a low caliber round Jackson-Pratt subcutaneous drain (10F) connected to a vacuum system that will be removed on post-transplant day 2 or 3

Device: ProGrip™ Self-Gripping Polyester Mesh

Monomax® USP 0 2 planes closure

NO INTERVENTION

The control group will proceed according to standard clinical practice with closure using the technique in 2 muscle-aponeurotic planes with very long-term (3 months) absorbable synthetic continuous suture of poly(4-hydroxybutyrate), monofilament, elastic (Monomax® USP 0) according to the small-bites technique. In order to achieve masking of the participating subject, a small-bore (10F) Jackson-Pratt drain connected to a vacuum system will be placed in the subcutaneous space at the end of the procedure in a manner similar to the intervention group. In both treatment groups, the subcutaneous drain will be removed on post-transplant day 2 or 3.

Interventions

Supra-aponeurotic placement of ProGrip® macroporous polyester mesh in the supra-aponeurotic position

ProGrip® Mesh reinforcement

PARTICIPANT, INVESTIGATOR, OUTCOMES ASSESSOR
Masking Details
For observer masking, the observer (outcomes assessor) will belong to the General Surgery team that is not directly involved with the transplantation procedure and agrees not to verify the assignment in the transplantation surgical protocol. Finally, the masking of the analyst (investigator) is achieved through collaboration with the Clinical Biostatistics Unit in the data analysis of the study (independent analyst) using a pseudo-anonymized database.
Purpose
PREVENTION
Intervention Model
PARALLEL
Model Details: Blinded parallel randomized clinical trial. A stratified allocation by the variable obesity will be performed using permuted blocks of variable size in each stratum. To guarantee the concealment of the randomization sequence, the randomization codes will be kept in opaque envelopes with correlative numerical identification that will be opened once it has been verified that the patient meets the inclusion criteria and has signed the informed consent form.

Will share

All data collected in the project will be recorded and stored in an electronic data capture tool developed for this project under REDCap (Research Electronic Data Capture, Vanderbilt University, TN, USA) that complies with national and international regulatory and legal requirements, including GDPR Regulation (EU) 2016/679. Data generated will be uploaded to provide access to the PI. Data will be shared by the PI only with the research team members. Access data security would be granted and supervised by the Data Protection Officer (DPO). All patient level data will be accessed only in coded and anonymized form. Once the objectives of the project have been achieved, the data used will be deposited in the internal REDCap repository of IRYCIS, which is the Institutional Repository of the Ramón y Cajal Health Research Institute. Access to the internal repository data for other researchers who may be legitimately interested in them will be subject to the approval of an ethics commission.
