Purpose
Loop ileostomy (LI) is commonly employed during colorectal surgeries to reduce the consequences of anastomotic leak. Unfortunately, LI is associated with a 10–30% incisional hernia (IH) rate after closure. We hypothesized that prophylactic mesh reinforcement during LI takedown would safely prevent subsequent IH formation.
Methods
This single-center, phase I/II prospective study evaluated adult patients undergoing LI closure after left-sided colorectal cancer procedures. After LI closure, the posterior rectus sheath was mobilized and reapproximated with absorbable suture. A reduced-weight, macroporous, polypropylene mesh (Softmesh, BD) was placed in the retrorectus position to allow 3 cm of overlap and secured with fibrin sealant. The anterior fascia was closed with slowly absorbable suture. CT images obtained for cancer surveillance were reviewed by a radiologist blinded to the study intervention to evaluate for evidence of hernia or surgical site occurrence (SSO).
Results
Twenty patients were included with mean defect and mesh sizes of 11.2 cm2 and 64.2 cm2, respectively. Mean operative time for LI takedown and mesh augmented closure was 84 min with mesh implantation time being 16.4 min. Two patients were readmitted within 30 days for ileus, no patient required procedural intervention. Over a mean follow-up period of 20 ± 7 months, no SSO or hernias were observed clinically or on CT imaging.
Conclusion
In our small series, retromuscular mesh reinforcement of LI closure appears feasible, safe and effective. This mesh reinforcement approach should be further investigated to evaluate its long-term effectiveness.
