P-130 LAPAROSCOPIC LUMBAR HERNIA REPAIR. BASED ON ANATOMICAL LANDMARKS AND SAFETY STATEMENTS

Abstract

Abstract Aim Lumbar hernias are a rare clinical entity (less than 1% of all abdominal hernias) and their surgical treatment is constantly evolving and changing. The aim is to propose a technical systematization of the steps and landmarks to perform a safe and effective repair of an infrequent pathology. Material & methods We use a tapp approach. The patient is placed in a dorsal decubitus position with a 45° elevation of the hernia side. The first port in the umbilicus access and two ports are placed along the middle line. Start the dissection using novel articulated instruments marking the anatomical limits of the rectangular trapezoid that involves the semilunar lines, epigastric vessels, spine, and imaginary line between the iliac crest and 11 th rib. Releasing the peritoneal flat until visualizing the psoas and quadratus muscles until the 12th rib, preserving the avascular plane avoids nerves and vascular damage. Hernia sac reduction. Tension-free or not closure of the orifice. Placement of a polypropylene mesh covering all the dissected areas. Mesh fixation using absorbable suture. Closure of the peritoneum.Vacuum maneuver and bulge compression. Results The systematic standardization has been applied to all patients. The mean operative time was 90 min. The articulated instruments were useful and allowed safe maneuvers. Outpatient surgery was achieved with a fast return to normal activity. The procedures were performed without intraoperative complications, mortality, or conversion to open surgery. Conclusion The step-by-step guide for anatomical landmarks and proven statements offers a safe and effective repair of this rare entity.
