P-085 MANAGEMENT OF LATERAL ABDOMINAL WALL HERNIAS

Abstract

Abstract Lateral abdominal wall hernias are rare and inconsistently defined, which is why the use of the EHS classification makes sense, not least for the purpose of comparing the quality of surgical results. A distinction must be made between true fascial defects and denervation atrophy. Based on the available literature, there is generally a low level of evidence with no consensus on the best operative strategy. The proximity to bony structures and the complex anatomy of the three-layer abdominal wall make lateral hernias difficult to care for. The surgical variability include laparo-endoscopic, robotic, minimally- invasive, open or hybrid approaches with different mesh positions in relation to the layers of the abdominal wall. The extensive preperitoneal mesh reinforcement open, transperitoneally laparoscopic (TAPP) or endoscopic extraperitoneally (TEP, TES) has met with the greatest approval. The extent of the required medial mesh- overlap is determined by the distance between the medial defect boundary and the lateral edge of the straight rectus-abdominal muscles. The lateral pre- and retroperitoneal dissection can be extended into the homolateral retrorectus compartment by laterally incising the posterior rectus sheath or can even be expanded by crossing the midline behind the intact linea alba into the contralateral retrorectus compartment. The “intraperitoneal onlay meshplasty” (IPOM) is only a suitable procedure for smaller and closable defects, but it is also important as an “exit strategy” in the case of a defective peritoneum.
