Incidence and risk factors for incisional hernia after temporary loop ileostomy closure: choosing candidates for prophylactic mesh placement
- 54 Downloads
The primary aim of this study was to identify the incisional hernia rate after temporary loop ileostomy closure. Secondary outcomes were determining the risk factors linked to this incisional hernia, which could improve the patient selection for mesh prophylaxis.
Retrospective cohort study of all consecutive patients with temporary loop ileostomy reversal through a peristomal incision from 1st January 2011 to 1st January 2017 at our centre. Data were extracted from electronic clinical records: baseline patient characteristics, surgical factors and postoperative events. CT scans performed during follow-up were precisely analysed. Survival analysis was applied to identify risk factors for hernia development.
129 patients were analysed of whom 15 (11.6%) developed an incisional hernia at previous ileostomy site. The median time for incisional hernia development was 11 months (IQR = 7–21) and the median follow-up time was 37 months (IQR = 22–57). The identified patient risk factors for hernia development in survival analysis were female sex, older age, higher Body Mass Index, clinically significant parastomal hernia, clinically detectable midline incisional hernia and major postoperative complications ranked as Clavien–Dindo grade III and IV.
Incisional hernia after temporary loop ileostomy is a relevant problem that affects at least one in every ten patients. The previously cited risk factors might favour its development, therefore the use of a prophylactic mesh should be considered in those high-risk patients.
