Effect of Sublay Preventive Mesh for Terminal Colostomy on Symptoms and Quality of Life in Patients With Parastomal Hernia: A Post-Hoc Analysis of the GRECCAR 7 Cohort.

Abstract

Recent randomized clinical trials and meta-analyses confirm that the use of a prophylactic mesh doesn't significantly reduce the parastomal hernia rate. Data about the benefits of these meshes concerning the symptoms of the parastomal hernia lack in the existing literature. The aim of this study was to perform a post-hoc analysis of the patients presenting parastomal hernia from the GRECCAR 7 randomized clinical trials cohort on whether the presence or absence of the mesh influenced the symptoms, the quality of life and complications of patients with parastomal hernias. We studied the parastomal hernia related symptoms among the two groups of the GRECCAR 7 randomized clinical trial, with or without prophylactic mesh at the time of the index surgery. Data were retrospectively extracted and analyzed from the GRECCAR 7 database. Patients diagnosed with a parastomal hernia during the two years of the GRECCAR 7 study. Several prospectively collected data about the symptoms were studied among this population. We also studied the average interval between parastomal hernia repair surgery and both index surgery and diagnosis of parastomal hernia. Among the 199 patients included in the GRECCAR study, 36 patients (35.6%) were diagnosed with clinical and/or radiological parastomal hernia in the non-mesh group at 2 years follow-up and 33 (33.7%) in the mesh group, without statistically significant difference (p = 0.89). None of the studied symptoms showed any statistically significant difference between the groups. This study relies on a relatively small number of patients, and although data were prospectively collected, we lacked some details about the categorization of the parastomal hernias. We believe that the use of a prosthetic mesh in a sublay position to prevent parastomal hernia in terminal end colostomy patients should no longer be recommended. See Video Abstract.
