Abstract
Abstract
Aim
To compare the early outcomes of two different techniques for ventral hernia repair in our abdominal wall surgery unit.
Materials and Methods
A prospective non-randomized review was perfomed including patients who underwent laparoscopic hernia repair from January 2018 to April 2022. All patients were followed-up for 1 month and the hernia orifice was closed in all cases. Patients and hernias characteristics, operative data and early complications were reviewed. Postoperative pain was defined as ≥4 value in Visual Analogue Scale.
We compared 2 laparoscopic techniques: intraperitoneal mesh fixed with a double crown of resorbable tackers (IPOM+) and self gripping sublay positioned mesh (preperitoneal –PREP- or retromuscular –RIVES- position).
Outcomes
During the study period, 44 patients were assigned into 2 groups: 31 (70%) in IPOM+ group and 13 (30%) in Rives/Preperitoneal group. No differences were found in risk factors, population and hernia data between both groups. 6 patients (19%) from IPOM+ group presented postoperative pain and only 1 patient (7,7%) in Rives/Prep group (p: 0,30). There was no differences in other complications, length of stay or operative time.
Conlusion
Early outcomes of sublay techniques (Rives or preperitoneal) do not report more complications during perioperative time, but they could help reducing immediately postoperatorive pain.

P-102 THE USEFULNESS OF EXPERIMENTAL ANIMALS IN LEARNING LAPAROENDOSCOPIC VENTRAL HERNIA SURGERY. Br J Surg 2022.

Abstract
Abstract
Aim
To study the usefulness of learning in simulation and animal model to incorporate laparoendoscopic techniques in ventral hernia in an abdominal wall unit.
Material and Methods
The training consists of 3 phases and four surgeons participate in it.
In a first phase, videos of laparoendoscopic ventral hernia surgeries are displayed.
In the second phase, 3 sessions are carried out in a simulation box to practice the zenith suture with a 5 cm diameter defect.
For the third phase, each surgeon has four sessions of surgery with swine models; In the first three, a retromuscular dissection procedure was performed, creating and suturing a midline defect of 15×4 cm (long and transverse diameter), placement of mesh in a retromuscular position, and closure of the posterior sheath (laparoscopic RIVES). In the 4th animal model, an extraperitoneal procedure was performed (eTEP) without closure of the posterior rectus sheath.
The total time of the intervention and the time used in the zenith suture are analyzed.
Results
With the first experimental animal, the average time used in suturing was 47.5 minutes, and in the fourth animal it dropped to 35 minutes. The time used to perform the laparoscopic RIVES in the first animal model was 102 minutes and was reduced to 72 minutes in the third.
Conclusions
Simulation and training models of minimally invasive ventral hernia surgery are useful and necessary in the training of surgeons and improve procedure times and skills.

Abstract
Abstract
Aim
Show the possibility of training abdominal wall laparoendoscopic techniques in the animal model.
Material and Methods
The training consists of 3 phases; in a first phase, videos of laparoendoscopic ventral hernia surgeries are displayed. In the second phase, 3 sessions are carried out in a simulation box to practice the zenith suture with a 5 cm diameter defect.
For the third phase, each surgeon has four sessions of surgery with swine models; In the first three, a retromuscular dissection procedure was performed, creating and suturing a midline defect of 15×4 cm (long and transverse diameter), placement of mesh in a retromuscular position, and closure of the posterior sheath (laparoscopic RIVES). In the 4th animal model, an extraperitoneal procedure was performed (eTEP) without closure of the posterior rectus sheath.
After training, these surgical techniques have been performed on patients
Results
The video shows the similarity of the animal model with the patient to perform the following technical steps; opening of the posterior rectus sheath, left retrorectal space dissection, midline crossover, right retrorectal space dissection, zenith suture of the anterior rectus sheaths, retrorectal mesh positioning and posterior rectus sheath suture.
Conclusion
Simulation and training models of minimally invasive ventral hernia surgery are useful and necessary in the training of surgeons.
