Parastomal hernia repair

Despite significant advances in abdominal wall reconstruction, parastomal hernias remain a complex problem, with a high risk of recurrence following repair. While a number of surgical hernia repair techniques have been proposed, there is no consensus on optimal management. Several clinical variables must be considered when developing a comprehensive repair plan that minimizes the likelihood of hernia recurrence and surgical site occurrences. In this review, we describe the incidence of parastomal hernias and discuss pertinent risk factors, medical history findings, physical examination findings, supplementary diagnostic modalities, parastomal hernia classification systems, surgical indications, and repair techniques. Special consideration is given to the discussion of mesh reinforcement, including available biomaterials, anatomic plane selection, and the extent of mesh reinforcement. Although open repairs are the primary focus of this article, minimally invasive laparoscopic and robotic approaches are also briefly described. It is our hope that the provided surgical outcome data will help guide surgical management and optimize outcomes for affected patients.
