This novel modification allows a simpler dissection of the preperitoneal retromuscular space and makes the TAR technique easier to perform. It also enables to incise only the insertion of the transversalis fascia cranially.
Temporary abdominal closure with ePTFE mesh is an effective alternative in some circumstances. We observed a higher survival rate than the predicted figure and there were no cases of enteroatmospheric fistulae using this particular surgical technique. ePTFE facilitates definitive abdominal wall closure, once the patient is in a stable condition.
Aim To present our initial results of abdominal wall surgery in dirty situations with an ovine rumen (OR) biologic mesh reinforced with polypropylene. Patients and Methods Five patients with elective abdominal wall surgery in a dirty setting were included. Two cases were previous PTFE mesh infections after IPOM repairs, one case of enteroatmospheric fistula through a previous posterior component separation repair, one deep tissue infection after a MILOS retromuscular repair and one definitive closure after a 8 weeks open abdomen in a liver transplantation patient. In the five cases cultures showed polymicrobian infections. Both PTFE meshes were removed and substituted by the OR biologic mesh. In the enteroatmospheric fistula patient the exposed mesh was resected together with the fistula take down, and a re-Rives was performed. In the case of the MILOS deep tissue infection after two weeks with an open abdomen and a temporary abdominal closure the definitive closure was performed with the biologic mesh in the retromuscular space. In the definitive closure of the liver transplantation patient the mesh was placed intraperitoneally as prophylaxis. Results In four cases there weren´t any surgical sites ocurrences. In the case of the enteroatmospheric fistula the patient presented a partial fascial dehiscence with mesh exposure, managed with a VAC system. With less than a year follow up no hernia recurrence has taken place. Conclusión The use of an OR biologic mesh with polypropylene reinforcement seems to be safe in abdominal wall repair in dirty settings, with good results during early follow up.
Aim Endoscopic lateral incisional hernia (IH) repair provides advantages in terms of low infection rates and hospital stay when compared with open repair. Material and Methods 62 years old men with a history of HTA and an open radical right nephrectomy for a renal tumor, developed a symptomatic iliac IH. L2–3 W2 according to the European Hernia Society (EHS) classification was clinically diagnosed and confirmed with a CT scan. Full endoscopic abdominal wall repair with defect closure was proposed. 3 trocars in right retrorectus space were placed. Once the lateral edge of the rectus sheath is reached, the posterior rectus sheath is incised, access to the preperitoneal lateral plane. During hernia sac dissection, an opening of the hernia sac occurs. The posterior layer is closed by a barbed suture, an accessory trocar placement was necessary for the closure. Subsequently, the internal oblique and transversus abdominis muscles that formed the defect were approximated with a barbed suture. During dissection, a right inguinal hernia was identified and repaired. A trimmed 20 x15 cm polipropilene mesh is placed in the preperitoneal space without fixation. Results The patient was discharged on the 3rd postoperative day without complications. Follow-up in the outpatient clinic at 6 months did not show any signs of recurrence. Conclusion Endoscopic abdominal wall reconstruction with posterior component separation is an alternative to the open procedure for lateral IH, providing a complete abdominal wall repair. The mesh is placed extraperitoneal with the advantages in terms of less adhesions and postoperative pain.
