Abstract

Background: It has been suggested that patients presenting with an inguinal hernia have an increased risk for colorectal cancer. Therefore, surgeons frequently request screening for colorectal cancer before surgery. The aim of this study was to assess the frequency of premalignant and malignant colonic lesions in a group of patients with an inguinal hernia, and to compare this with a control group of subjects undergoing screening colonoscopy. Methods: In a case-control study, 243 patients with an inguinal hernia and no history of colonic neoplasia or symptoms suggestive of colorectal cancer underwent perioperative colonoscopy. The patients were stratified into two age groups: less than 50 years old (Group I) and more than 50 years old (Group II). The colonoscopic findings were compared with findings in 534 asymptomatic control patients who underwent screening colonoscopy. Results: The mean age of patients (n = 64) and control subjects (n = 200) in Group I was similar, at 44 (3) years. The mean age of the patients (n = 179) and control subjects (n = 334) in Group II was, respectively, 70 (9) years and 64 (7) years (p <0.001). In Group I, no colorectal cancer was found in patients with inguinal hernia, and only one colorectal cancer was found among control subjects (p = 0.571). In Group II, a diagnosis of colorectal cancer was made in 7 patients (4%) with inguinal hernia as compared with 10 patients (3%) among the control subjects (p = 0.769). In both groups, the size and the histopathologic type of the polyps were not significantly different. Conclusions: In otherwise asymptomatic patients, the presence of inguinal hernia is not associated with an increased risk for colorectal cancer. Therefore, the presence of an inguinal hernia alone does not justify screening colonoscopy before herniorrhaphy.
