Long-term parastomal hernia occurrence rate following Stapled Mesh stomA Reinforcement Technique

Abstract

PURPOSE: Our initial publication on Stapled Mesh stomA Reinforcement Technique (SMART) for the prevention of parastomal hernias (PSH) demonstrated promising results. The aim of this study is to evaluate the long-term PSH occurrence rate with SMART and its associated complications and to radiologically measure the progression of trephine diameters. MATERIALS AND METHODS: All SMART cases from November 2013 to July 2016 were reviewed. Demographics, peri-operative details, and long-term mesh-related complications were collected. Serial computed tomography (CT) scans during follow-up were used to identify PSH and measure the progression of axial and sagittal trephine diameters and trephine area. RESULTS: 15 patients (M:F = 10:5) underwent an elective stoma formation with SMART. Nine died during the study period. Two patients died before any CT scan with no clinical evidence of PSH. All except one of the remaining 13 patients developed radiological PSH. There were no long-term mesh-related complications. Only one patient required the relocation of stoma due to the incarceration of small bowel in the PSH in an emergency setting. The median follow-up was 28 months (3–77 months). CONCLUSION: Prophylactic mesh placement by SMART did not prevent the occurrence of PSH in the long-term despite only a minority of patients required surgical intervention for PSH.
