Materials and methods Seventy-two selected patients
with clear risk factors and colon pathology underwent
surgical intervention through median infraumbilical laparotomy.
During laparotomy the preperitoneal space was
dissected at a point where a low-molecular weight polypropylene
mesh was to be placed when closing the peritoneum.
Meshes were about 7–8 cm wide and had a
variable length that depended on the length of the surgical
incision. Of the 72 patients, 41 were obese (BMI[30 kg/
m2), 45 presented with COPD, and 42 with colorectal
neoplasia; 29 patients had two risk factors, and 15 had
three risk factors. The mesh was held in place with polypropylene
stitches in 28% of cases, and with fibrin glue in
72% of cases.
