Aim To analyze the treatment and complications of gigant paraestomal eventration with a case report and literatura review Material and Methods a retrospective case report from our hospital and her evolution since her urology surgery in 2011 Results Female of 59 years old, with personal antecedents of arterial hypertension, simple cistectomy and Bricker's urinary derivation (cutaneus ureteroileostomy) in 2011 due to intersticial cistitis, parastomal incisional hernia repair with intraperitoneal mesh in 2015. The patient was derivated from urology consult for a huge paraestomal incisional hernia and personal history of obstructive uropathy and several infections of urinary tract since 2022. No obstruction clinic was associated. Elective surgery was performed with an Trasversus Abdominis Release (TAR) and moving previous urostoma: hernial sac disection and previous mesh explant. Opening Rives, Retzius spaces and transversus fasciotomy was realized. Middle line was reforzed and hernial defect was closed. Polipopilene mesh was fixed at middle line and pubis with no reabsorbible suture and reforced with haemosthatic sealant. Anterior fascia was closed fixing at middle line. At the end a new urostoma was made in ryght hypocondrium. In postoperative period the patient developed light anaemia. Following months, the patient has not other complications due to incisional hernia repair. Conclusions Many factors can contibute to incisional hernia such as obesity, hypertension, number of surgerys, age, sex… TAR technique can be useful with complex eventration but we can not forget the commorbilities association to this surgery (anemia, pulmonar Tromboembolism…)

Aim The short-term results of the use of seprafilm® as a reinforcement of the peritoneum are presented. Material and Methods Seprafilm® was used in 5 patients with large midline and lateral incisional hernia in which Transversus Abdominis Release Technique was performed in which it was necessary to explant mesh previously. This weakness of the peritoneum was reinforced with the seprafilm® plates, to isolate the intra-abdominal contents from the mesh. Results The patients treated had an average stay of 6.6 days. All of them carried drains. There were no infectious complications in surgical site. There were no prolonged pain. All of them began tolerance the day after the surgery. At one month of the surgical intervention, there were no signs of infection, seroma or higher pain than 3 on the EVA scale. Discussion Post-operative adhesions to mesh are related to intestinal fistulas. The use of preperitoneal space to place the mesh is a good option, although sometimes it can have continuity problems, especially when there are explants of previous materials. The use of barrier materials is appropriate in these cases. Conclusion The use of Seprafilm® can be a good option as a barrier between viscera and prostheses for the prevention of adhesions.
