OV11 GIANT SPIEGEL HERNIA: 3D PLANNING AND MINIMALLY INVASIVE TREATMENT

Abstract

Abstract Aim Demonstrate the advantages of 3D technology planning in complex cases of hernia surgery and technical tricks for giant Spiegel hernia repair. Material and Methods 71 year old patient, BMI 38, asthma, hypertensive; long history of symptomatic left flank mass. Giant Spiegel hernia was diagnosed, with significant omentum and colon migration to hernial cavity. It was decided to perform minimally invasive surgery. 3D model of the abdominal scan was performed, assessing hernia size, volume and its relationship with the abdominal cavity. We were able to rule out the possibility of compartment syndrome, and foresee that we could probably close the defect. Results preperitoneal transabdominal repair (TAPP) is performed, beginning with herniated content reduction, a delicate step where injuries should be avoided, with careful traction of the colon and omentum. Hernial defect is assessed, coinciding with the 3D model, the peritoneum sac is reduced, taking as much as possible to facilitate its posterior closure. The entire peritoneum of the Spiegel and inguinal region are dissected en bloc. Defect tension-free closure is performed with 2 continuous V-LOOK 2.0, subsequent placement of 15x15cm polypropylene mesh and posterior peritoneum closure. The patient is discharged the same day without incidents. Conclusions The 3D model allows us to assess the actual abdominal and hernia volume to simulate surgery findings. Its benefits are yet to be developed. Laparoscopic preperitoneal repair is an excellent approach for Spiegel's hernia. Complex cases are also candidates for outpatient surgery.
