Preperitoneal mesh repair of spigelian hernias under local anesthesia: description and clinical evaluation of a new technique

Abstract

We report on a new method for the repair of spigelian hernia, in which we combined the step-by-step local anesthesia and open preperitoneal mesh repair techniques. After initial infiltration of local anesthetics, we incised the attenuated fascia and slightly enlarged the fascial defect to facilitate easy return of hernial content into the abdominal cavity. We injected preperitoneally, in a radial fashion around the peritoneal sac, more saline solution, consisting of 1:200,000 epinephrine (g:g) and ⅓ bupivacain (v:v). We dissected the peritoneum away from the anterior abdominal wall to create a preperitoneal pocket of sufficient size. We spread open a 9×9-cm polypropylene mesh in the area, as if we were doing a GPRVS of Stoppa. We followed up our four patients for an average of 32 months. All four cases had an uneventful recovery and were discharged in an average of 3.5 days. They returned to normal daily activity on the 9^th day after surgery. We suggest that the preperitoneal mesh repair of a spigelian hernia under local anesthesia is a simple and feasible technique with favorable early and late postoperative results and deserves further investigation in larger series.
