Inguinal hernia repair in overweight and obese patients

PURPOSE To describe the clinical characteristics and outcomes after inguinal hernia repair in overweight and obese patients. METHODS We retrospectively reviewed the medical records of 636 adult patients who underwent mesh plug inguinal hernia repair performed by one surgeon from November 2001 to January 2009.The clinical characteristics and surgical outcomes of the patients were analyzed. According to the body mass index, patients higher than 23 were defined as overweight and obese patient group (O group) and patients between 18.5 and 23 were defined as normal weight patient group (N group). Seventeen underweight patients were excluded in this study. RESULTS Of 619 cases, the number for O group was 344 (55.6%) and for N group was 275 (44.4%). The mean age was significantly higher in N group (62.2 ± 12.6 vs. 64.4 ± 14.8, P = 0.048). Underlying diseases were present in 226 (65.7%) of the O group and 191 (69.5%) of the N group (P = 0.322). Anesthesia method, operative time and postoperative hospital stay had no significant difference between the two groups. Postoperative complications developed in 41 (11.9%) of the O group and in 28 (10.2%) of the N group, respectively, and no major complications developed in either group. CONCLUSION Adult inguinal hernias developed at a relatively younger age in overweight and obese patients than in normal weight patients. There were no specific differences in other clinical characteristics and outcomes between the two groups. Therefore inguinal hernia repair in overweight and obese patients is a safe procedure as in normal weight patients.
