V-004 ROBOTIC PARASTOMAL HERNIA REPAIR WITH RETROMUSCULAR MESH (PAULI TECHNIQUE)

Abstract

Abstract Aim Parastomal hernia is a common complication of ostomy formation. We present a case of robotic parastomal hernia repair with retromuscular mesh (Pauli technique). Material and Methods Patient was 58 years-old man and had history of anterior resection of the rectum, terminal colostomy and onlay mesh parastomal hernia repair. After 2 months of parastomal hernia repair, the patient developed a recurrence (type III, European Hernia Society Classification). Results Robotic parastomal hernia repair was performed with transabdominal approach. Firstly, a small adhesiolysis of the colon to the stoma orifice was made. Then, the peritoneum and posterior sheath of the left rectus muscle was incised. The retrorectal space was dissected. The hernia sac was incised circumferentially. TAR dissection was launched lateral to the stoma. After the development of the landing zone for the mesh, the posterior retromuscular fascia was incised lateral to the stoma. The inner orifice of stoma was repositioned. A large-pore polypropylene mesh (20×28 cm) was placed in the retromuscular space and fixed it, lateral to the ostomy orifice. Finally, the retromuscular pocket was closed by suturing the posterior fascia to the linea alba. The patient was discharged on postoperative day 4 and had no complications. After 4 months of follow-up, no hernia recurrence had been recorded. Conclusions Robotic Pauli is a technique to repair parastomal hernias that provides wide coverage of the defect and avoids leaving mesh intraperitoneally. They could provide a secure repair and prevent postoperative complications (pain or intestinal ileus). It is technically challenging but feasible.
