V-017 TOTALLY ENDOSCOPIC APPROACH TO MODIFIED SUGARBAKER PARASTOMAL HERNIA REPAIR BY TRANSVERSUS ABDOMINIS RELEASE (ETEP-PAULí). ADVANTAGES OF RETROMUSCULAR/PREPERITONEAL MESH PLACEMENT

Abstract

Abstract Several studies published have shown that TAR is an effective technique for reconstructing midline hernias and lateral hernias. In 2016, Pauli et al. described a novel technique for parastomal hernioplasty using open TAR combined with a modified Sugarbaker repair.A 56-year-old woman operated on 5 years earlier due to rectum adenocarcinoma by laparoscopic resection. A parastomal hernia was diagnosed. CT revealed a 5 cm wide parastomal hernia associated with an umbilical hernia.Patient is placed in the supine position. Identification by ultrasound of the lateral junction of right rectus sheaths. incision on subcostal region 1 cm medial to said juntion. An incision is made on the anterior lamina and retromuscular space is created with a dissection balloon. With the placement of two 11–5 trocars, the medial aspect of the posterior rectus sheath muscle is incised at the epigastric level and the Crossover is carried out. Left retromuscular dissection is performed. The hernia content is reduced. the left arcuate ligament is identified and the transverse abdominis muscle is released. Anterior defect closure with barded suture. An horizontal peritoneal incision is performed with the aim of lateralizing the colonic stump, the peritoneum and posterior aspect of the rectum sheath are closed.Placement of PPL mesh of 25×30 cms covering the dissected space.Patient was discharged on postoperative day 2. No complications or hernia recurrence were identified. Conclusions This technique offers some advantages; Coated mesh is unnecessary,The retromuscular positioning permits the integration on both sides.However several drawbacks; lack of long-term outcomes and technically challenge.
