Standard Closure vs. Integrated Mesh-Fascial Closure (IMFC) for Incisional Hernia Repair (IMFC)
Prospective Comparative Evaluation of the Integrated Mesh-Fascial Closure (IMFC) Technique Versus Standard Closure of the Abdominal Wall: A Quasi-Experimental, Non-Randomized Study
This study compares two surgical techniques for closing the abdominal wall in adult patients who have an incisional hernia (a weakness or opening in a previous surgical incision) or who require prophylactic mesh placement during a laparotomy.
In one group, the abdominal wall is closed using the standard technique, in which a polypropylene mesh is fixed independently from the fascial suture. In the other group, Integrated Mesh-Fascial Closure (IMFC) is used, a standardized execution of the technique of mesh incorporation into the fascial closure described by Jamal et al (Hernia, 2013).
The choice of technique is made by the patient after receiving information about both options and providing informed consent. Participants will be followed clinically and with imaging for 18 to 24 months to evaluate the safety, technical feasibility, and reproducibility of the IMFC technique, and to determine the incidence of hernia recurrence in both groups.

详细说明
Incisional hernia is one of the most frequent complications of abdominal surgery, with a reported incidence of 10-20% after laparotomy, and recurrence rates after mesh repair reaching 20-30% in long-term follow-up. In conventional techniques, primary fascial closure and mesh fixation are performed as two mechanically independent steps, concentrating tension on the suture line during the acute postoperative period.
The Integrated Mesh-Fascial Closure (IMFC) technique integrates a macroporous polypropylene mesh within a continuous fascial suture line (pattern: mesh → right fascial edge → left fascial edge → mesh), aiming to distribute tensile load simultaneously between the fascia and the prosthesis, potentially reducing the incidence of hernia recurrence compared to standard closure. The principle of incorporating the mesh into the fascial closure was described by Jamal et al in a retrospective series of 72 patients. IMFC standardizes its execution (suture material, 5-mm bites in mesh and fascia, anchoring of the suture line in healthy aponeurosis, and optional minimal peripheral fixation) and evaluates it prospectively against standard closure.
This is a prospective, comparative, quasi-experimental (non-randomized) study conducted at a single center (Hospital Zonal General de Agudos "Dr. Mario V. Larrain," Berisso, Argentina). Eligible patients choose, after informed consent, between standard mesh closure (Group A) or IMFC (Group B). Both groups follow the same clinical and imaging follow-up schedule (days 7, 15, 30; months 2, 6, 12, 18; and a final visit between 18 and 24 months).
The study is designed as an initial, hypothesis-generating comparison of safety, technical feasibility, and reproducibility across surgeons, intended to support a future randomized trial.

Recurrence rate of incisional hernia
大体时间:18-24 months (final follow-up visit)
|
Proportion of participants with hernia recurrence, assessed by clinical physical examination and abdominal wall ultrasound, performed in all participants at 6 months and at the final visit (18-24 months). All ultrasound evaluations performed by the same sonographer throughout the study; the sonographer is aware of study participation but blinded to the specific surgical technique (IMFC vs. standard closure) received by each participant. |
