Brief Summary:
Study Design Single-blinded randomized prospective clinical trial Study Population End-stage liver disease patients candidates for liver transplantation
Study procedures Consenting patients will be divided into two matched groups
1 CONTROL group - receiving a standard running fascial closure with PDS suture
2 TREATMENT group - receiving a standard running fascial closure with PDS suture PLUS a low molecular weight mesh The mesh will be secured to the fascia extending 3 cm from the incisional site
There will be no modifications to routine post-operative wound care in both groups However the treatment group will have an additional drain placed at the incision site compared to the control group to reduce the risk of a seroma from placement of the mesh Wound dressing will be removed on post-op day 2 and the wound will be assessed Re-application of the dressing will occur thereafter until proper healing of the incision
An abdominal ultrasound will be done on all study participants at the 1- and 2-year mark postoperatively to look for objective evidence of a ventral incisional hernia A CT scan will be performed if the abdominal ultrasound findings are inconclusive

Detailed Description:
An incisional hernia is a common complication of abdominal surgery with an incidence of 4-20 Liver transplant patients represent a unique cohort of surgical patients with immediate immune suppression post-operatively It is presumed that this immune suppression accompanied by significant co-morbidities have led to high incisional ventral hernia rates between 49-343
A recent 2018 retrospective review of 1044 liver transplant patients identified age 55 high BMI 25 and immediate rejection were significant risk factors contributing to herniation However previously concerning considerations including gender diagnosis diabetes Child-Pugh score MELD score donor type hepato-renal syndrome varix bleeding ascites hepatic encephalopathy ventilator use spontaneous bacterial peritonitis SBP or bile leak were not identified as significant risk factors Moreover the mortality for chronic liver disease patients for elective hernia repair is 37 at 90 days and morbidity is 27 Emergent hernia repair led to 10 90-day mortality with 60 morbidity The high incidence of herniation represents a common problem with significant morbidity and mortality post liver transplantation thereby requiring investigating a new preventative solution
A recent retrospective trial in the colorectal literature identified an institutional incidence of incisional hernia for colorectal patients of 399 They recognized two high-risk populations obese and non-obese with a combination of several secondary risk factors A follow-up prospective cohort study separated all colorectal patients undergoing laparotomy to standardized running PDS closure versus those with BMI29 the median in the prior study and those BMI 29 with 2 risk factors to include standard closure with an on-lay Ultrapro partially absorb-able mesh covering 3 cm adjacent to the incision placed with double down facial staples followed by a subcutaneous drain The reported risk factors included BMI smoking serum creatinine hemoglobin serum albumin COPD diabetes immune suppression with steroids or radiationchemotherapy and previous midline laparotomy The results revealed a decrease in the incisional hernia rate from 439 to 10 P00001 This study also concluded the treatment was cost effective and safe
