The advantage of laparoscopic surgery in the treatment of Spigelian hernia: A report of two cases

Abstract

Introduction and importanceThe usefulness of laparoscopic surgery in the treatment of Spigelian hernias and the appropriate insufflation pressure remains unclear.Case presentationCase 1 involved an 81-year-old woman presented with a right abdominal protrusion. CT scan demonstrated a defect in the abdominal wall at the lateral edge of the right rectus abdominis muscle. We diagnosed as Spigelian hernia and performed laparoscopic hernia repair. The insufflation pressure was set at 10 cm H 2 O, and the IPOM method was selected as the repair method. Case 2 involved a 74-year-old male presented with a right abdominal painful bulging. Strangulation was released and CT scan demonstrated a defect in the abdominal wall at the lateral edge of the right rectus abdominis muscle. We diagnosed as Spigelian hernia and performed laparoscopic hernia repair. The insufflation pressure was set at 10 cmH 2 O, and the repair was performed by the hybrid method.Clinical discussionIn both cases, the positions of the hernia portals marked preoperatively based on the tender areas and confirmed laparoscopically were not accurate. Although Spigelian hernia is a rare disease and various laparoscopic techniques have been reported in recent years, laparoscopic surgery is very useful to obtain an accurate diagnosis and to observe the abdominal wall from inside the abdominal cavity under insufflation, and it is better to decide the repair method according to the situation of each case and institution.ConclusionLaparoscopic surgery is important for accurate diagnosis in surgery of Spiegel's hernia, and insufflation pressure of 10 cmH2O was sufficient.
