A case series analysis of spigelian hernia: A diagnostic dilemma and its successful laparoscopic repair.

Abstract: A Spigelian hernia is an uncommon, atypical protrusion of the peritoneum or abdominal contents via a defect (Spigelian fascia), consisting of the internal oblique aponeuroses and the transversus abdominis. With a frequency ranging from 0.12% to 2% of all abdominal wall hernias, Spigelian hernias are extremely rare. It usually arises from a condition that increases intra-abdominal pressure, the degeneration of the abdominal aponeurotic layers or trauma to the abdominal wall. Herein, we present a case series of patients with varying presentations of Spigelian hernia who presented, who were promptly diagnosed and who were managed successfully with laparoscopic surgical repair.
