Spigelian hernia long considered as diverticulitis: CT scan diagnosis and laparoscopic treatment. Computed tomography.
Spigelian hernia (SH) develops in the spigelian aponeurosis. In some cases, its clinical symptoms may mimic those infrequently the diagnosis of sigmoid diverticulitis. Herein we report the case of a patient who for 12 years experienced a pain and a mass in the left lower quadrant that appeared after straining and then disappeared again after rest. A diagnosis of sigmoid diverticulitis was made. She was admitted to hospital for the acute onset of an intense abdominal pain in the left lower quadrant associated with fever. Physical exam showed a 10 x 15 cm mass in the left lower quadrant. Computed tomography (CT) scan showed a left-sided SH containing a small bowel loop and a sigmoid loop. The SH was reduced easily with bed rest and external pressure. Under laparoscopy, a Gore-Tex mesh was stapled on the posterior side of the anterolateral abdominal wall so that it widely covered the abdominal wall defect. The reducible SH, the incarcerated SH, and the strangulated SH represent the majority of the clinical aspects of SH. Although many differential diagnoses are proposed, but the diagnosis of sigmoid diverticulitis is an infrequent one. Ultrasound (US) scan or a CT scan that shows the defect in the abdominal wall, the hernial sac, and its contents is an easy means of confirming the diagnosis of SH. SH can be treated through a direct approach or through a midline laparotomy. Laparoscopy is advisable for a tension-free treatment with an intraperitoneal mesh. It is important to make the diagnosis of SH before its strangulation. For that reason, CT scan and US scan are highly recommended. Laparoscopic treatment, which is effective and safe, is advisable in such cases.
