A multicenter study evaluated the effectiveness of a funnel-shaped intra-abdominal mesh in reducing parastomal hernia (PSH) rates following rectal cancer surgeries with colostomy. The Chimney Trial involved 143 patients in Finland and Sweden, comparing outcomes at 3 years between those receiving mesh and those without. Results showed significantly lower CT-confirmed PSH in the mesh group (57%) versus the control group (82%). However, both groups had similar quality of life and reoperation rates, highlighting challenges in assessing chronic conditions like PSH.
