Linea semilunaris: a curved vertical line on the anterior abdominal wall at the lateral edge of each rectus abdominis muscle Herniation of intra-abdominal contents through the linea semilunaris is known as a Spigelian hernia . 2011 Apr;21(2):76-81. This type of hernia is rare and usually difficult to diagnose due to the location and hazy imprecise symptoms. While most patients only present with abdominal pain, at least 1/5th of patients present with bowel obstruction [1] [2] [3]. This hernia is the result of a weakness of the linea semilunaris, which is the fibrous sheath of tissue between the rectus abdominis muscles and the transverse and oblique abdominal muscles of the lateral abdominal wall. A spigelian hernia is a peritoneal protrusion through the spigelian fascia that traverses the transversus abdominis and internal oblique aponeuroses and spreads beneath the intact aponeurosis of the external oblique.

There were 32 (76%) women with a mean age of 52.1 years. The surgical treatment is the same as for any hernia. The hernia usually occurs because of weakness in the supporting tissues and presents with vague abdominal pain and sometimes a small mass. Spigelian: Defect in transversus abdominis fascia alongside lateral border of rectus abdominis muscle (linea semilunaris) and lateral border of rectus sheath Schematic diagram shows a paraumbilical hernia arising from the umbilicus area.

PMID: 5593138 [PubMed - indexed for MEDLINE] MeSH Terms Adult Female Hernia, Ventral*/diagnosis The primary defect occurs in the spigelian fascia, which is the anatomical area along the lateral edge of the rectus muscle and aponeurosis of the transversus abdominus muscle. The majority of types of hernia are located subcutaneously beneath the fat layers, so the presence might be felt as swelling that is abnormal. It appears that these hernias are not very common and only isolated reports exist. The surgery to repair a spigelian hernia has few complications and most people do not have recurrences. [symptoma.com], We report a 31 years old patient from the Sultan Qaboos University Hospital who presented with colicky lower abdominal pain associated with a tender swelling above and lateral to the inguinal canal. The prognosis for most patients with a spigelian hernia is excellent. Thus, the individual should refrain from lifting heavy weights, discontinue sports that require intense abdominal exertion, have benign prostate hypertrophy treated and eat a high fiber diet to prevent constipation. All spigelian hernias need surgical treatment.

De linea semilunaris (midden) waar de hernia spiegeli zich ontwikkelt Een hernia spiegeli, soms gespeld hernia spigeli (of laterale ventrale hernia) is een hernia door spiegelse fascie. The symptoms of a spigelian hernia are not specific and may include the following. A spigelian hernia is a hernia that occurs just about the pubis. There is no blood work that is specific for diagnosis of a spigelian hernia. Spigelian hernia is a very rare hernia of the abdominal wall. The average body mass index was 39 13 kg/m 2(range, 23â69 kg/m ).The average defect size was 366 2120 cm2 (range, 160â660 cm ). Defects in the aponeurosis of transverse abdominal muscle (mainly under the arcuate line and more often in obese individuals) have been considered as the principal etiologic factor. The hernia sac is identified and excised, the bowel contents are reduced and a mesh is used to repair the defect. Vega Y, Zequeira J, Delgado A, Lugo-Vicente H. Spigelian hernia in children: case report and literature review. 2013 Nov-Dec;84(6):649-53. Sie ist benannt nach dem flämischen Anatomen Adriaan van den Spieghel (1578â1625) However, because the test is very operator dependent, small hernias may be missed. This usually occurs at the meeting point of the linea semilunaris with the arcuate line and the lateral border of the rectus abdominis muscle. The surgery today is done via a scope and most patients can be discharged home the same day. Characteristically, patients sought medical advice several times without reaching a diagnosis [7].
