Prophylactic Biosynthetic Retrorectus Mesh Placement During Stoma Reversal Reduces the Rate of Stoma Site Incisional Hernia

The objective of this study was to assess the use of prophylactic biosynthetic mesh at the time of stoma reversal on the overall SSIH rate.METHODS: This is an observational retrospective cohort study. A review of 101 consecutive patients who underwent PMR in the retrorectus plane from 2015 to 2020 was compared to 73 consecutive patients who underwent primary stoma closure without mesh from 2011 to 2014. The primary endpoint was the presence of SSIH on clinical examination or computed tomography after ostomy takedown.RESULTS: In total, 174 cases were analyzed with 101 patients in the treatment group (median follow-up 45.2 months) and 73 patients in the control group (median follow-up 43.2 months). There were no major differences in preoperative characteristics between the groups. Fourteen patients developed SSIHs with 1 (1.0%) in the treatment arm and 13 (17.8%) in the control arm (p = 0.001). The majority of stomas were loop ileostomies and end colostomies, and stoma type did not affect hernia rates. On univariate analysis, body mass index (p = 0.029) and chronic kidney disease < 3 (p = 0.003) were independent predictors of hernia formation, while mesh was significantly protective (p = 0.000057).DISCUSSION: PMR with biosynthetic mesh at the time of stoma reversal and closure is an effective procedure to reduce the incidence of SSIHs and does not seem to be associated with an increased risk of complications.PMID:38652519 | DOI:10.7812/TPP/23.115
