Cord lipoma in minimally invasive surgical repairs of inguinal hernias: a prospective study.

Abstract

Cord lipomas are frequent findings in laparoscopic inguinal hernia surgeries in male patients. The symptoms of lipoma and the potential benefits of removing them are often overlooked because the focus is on the primary pathology of the hernia itself. Current recommendations are to reduce this fatty content, when present. When inguinal cord lipomas are left untreated in inguinal hernia surgery they can potentially cause symptoms and be detected in follow-up imaging exams. The objective of this study was to study incidence of cord lipomas in a cohort operated on by a single group specializing in abdominal wall surgery, as well as to analyze the possible relationship of this finding with the patient's symptoms, the characteristics of the operated hernia and postoperative outcome. This is a prospective study of male patients operated on for inguinal hernia laparoscopically or robotically in a single reference center. Of the total of 141 hernias, the distribution according to European Hernia Society classification showed that 45.4% were lateral, 19.1% medial and 35.5% mixed, highlighting a variety in the presentation of hernias. Analysis of the size of the hernias revealed that the majority (35.5%) were ≤ 1.5cm. Inguinal cord lipoma was present in 64.5% of the samples, with no statistically significant association between the presence of the lipoma and an indirect hernia sac or obesity. The incidence of surgical site occurrences (SSO) was 9,2%, with seroma and hematoma. No recurrences were observed during follow-up, indicating a successful approach. There were no statistically significant relationships between SSO, the presence of lipoma and indirect hernial sac.
