Brief summary

Hernia formation at sites of ostomy closure is a common complication. The investigator believes that using evidence based hernia repair techniques as a preventive measure during closure of ostomies will reduce the incidence of hernia formation. In this trial, the investigator will pilot a novel technique of large pore monofilament polypropylene mesh reinforcement of the abdominal wall defects that remain after closure of an ileostomy to evaluate for safety and begin to evaluate the effectiveness compared to standard techniques.

Interventions

Implantation of permanent mesh (BARD Soft Mesh) into the abdominal wall for reinforcement to prevent hernia formation

Intervention model description

Modified Simon-Two Step. An initial cohort of 5 patients will be enrolled and treated sequentially with 30 day follow-up. If stopping criteria are not met, the cohort will be expanded to an additional 15 patients followed concurrently for the duration of the study period

Inclusion criteria

1. Age \> 18years 2. Patient is undergoing closure of loop ileostomy 3. Patient has a diagnosis of left sided colon or rectal cancer treated with resection and diverting loop ileostomy 4. Patient has been evaluated by a qualified surgeon and found to be a suitable candidate for surgery

Exclusion criteria

1. Pre-existing systemic infection at the time of ileostomy takedown 2. Cirrhosis, chronic renal failure requiring dialysis, or collagen disorder 3. On current immunosuppression (anti-tumor necrosis factor (TNF) agents, chemotherapy, or prednisone \>10mg/day) 4. Previous abdominal hernia repair with mesh placement 5. Concurrent procedures in addition to closure of diverting loop ileostomy 6. Ileostomy closure not completed through the previous stoma site (i.e. those requiring exploratory laparotomy for closure)

Participant flow

Recruitment details

Adult patients (Interventional group)with left sided CRC who underwent proximal diversion with a LI as part of their surgical therapy were recruited from the clinical practice of the Division of Colon and Rectal Surgery at DHMC between January 2019 and November 2020. Historical Controls were patients diagnosed with colorectal cancer and who underwent stoma reversals from January 1, 2011, to December 31, 2018 from the clinical practice of the Division of Colon and Rectal Surgery at DHMC.

Pre-assignment details

24 Adult patients with left-sided colon and rectal cancer treated with resection and diverting loop ileostomy were eligible to participate. 4 participants declined participation and were not enrolled. Historical Controls. Data for only those who met the inclusion criteria was collected. Data collected was only relevant to the Primary endpoint, and additional follow-up date was no collected beyond the data needed for analysis for the primary outcome measure.
