Contrasting Presentations of Spigelian Hernia in a Single Surgical Unit of a Tertiary Healthcare Center: A Case Series

A Spigelian hernia is a very rare type of anterior abdominal wall hernia. The etiology revolves around the dehiscence of the transverse abdominis and internal oblique aponeurosis. The majority of Spigelian hernias develop in the lower abdomen where the posterior sheath is absent. This condition is also known as a spontaneous lateral ventral hernia or hernia of the semilunar line. It is mostly asymptomatic and is generally proven by radiological diagnosis. In the worst-case scenario, strangulation of the Spigelian hernia can occur. Here, we report a case series of contrasting presentations of Spigelian hernia in a single surgical unit of a tertiary healthcare center, considering the rarity and associated complications of Spigelian hernia.
