Background: Spigelian hernia (SH) can be defined as the protrusion of preperitoneal fat or a peritoneal sac containing or not containing an intra-abdominal organ, across a congenital or acquired defect in the Spigelian line. These hernias are also known as "spontaneous lateral ventral hernias", "hernia of the semilunar line," or "hernias through the conjoint tendon". Aim: To report the clinical features of this type of hernia. Material and Methods: Review of medical records of 23 patients aged 36 to 83 years (16 females) with Spigelian hernia treated in a lapse of 10 years. Results: Fifty two percent of the patients were obese. The hernia was unilateral in all patients and in 70% of cases, it was located in the left side. All patients referred pain. A palpable mass was found in 83%. An ultrasound was required to confirm the diagnosis in 22% of patients. All were subjected to elective surgery, with local anesthesia. No relapse has been detected. Conclusions: Spigelian hernia is uncommon and usually presents with pain. Its surgical correction can be carried out with local anesthesia.
