Richter's hernia is a rare condition in which a portion of the antimesenteric border of the intestine protrudes through the hernial defect, potentially leading to intestinal obstruction and severe complications if not appropriately treated. It is a condition of varying severity that can result in strangulation or incarceration, necessitating immediate surgical intervention. Although patients typically experience abdominal pain, symptoms can be vague, and the differential diagnosis should consider other conditions. In this context, computed tomography and/or ultrasonography are usually the preferred diagnostic modalities. The purpose of this study is to report and describe a successful case of Richter's hernia correction in a 66-year-old woman treated in our facility. During surgery, incarceration and signs of necrosis were identified in the hernial sac, requiring subsequent laparotomy for a more detailed evaluation of the incarceration.
