IntroductionIncisional hernias of the flank are rare with scattered case reports regarding the feasibility of laparoscopic treatment. Treatment can be technically challenging due to patient positioning and adequate mesh overlap and fixation. The aim of this study is to describe the surgical technique and present outcomes of the largest known case series of laparoscopic repair of flank hernia.MethodsA retrospective chart review was performed from April 2002 to August 2006 at two university hospitals utilizing three surgeons' experience. All patients who underwent a laparoscopic repair of a flank hernia were identified and reviewed with regards to short-term outcomes.ResultsTwenty-seven patients were identified with incisional flank hernia treated laparoscopically. Average defect size was 188 cm(2) repaired with an average mesh size of 650 cm(2). Mean operating room (OR) time was 144 min and mean length of stay (LOS) was 3.1 days. There were two reoperations within the cohort: one for a new, unrelated midline hernia 7 months after repair of the initial flank hernia and one for chronic pain with removal of a previously placed polypropylene mesh in the subcutaneous tissue of the abdominal wall. Neither patient had failure of the laparoscopic flank hernia repair. Two other patients were conservatively treated for chronic pain. Mean follow-up was 3.6 months.ConclusionsIn the laparoscopic repair of flank hernias adequate retroperitoneal dissection and wide mesh overlap is imperative. Laparoscopic repair can be performed safely and effectively with good short-term outcomes.
