BACKGROUND: A Spigelian hernia is rare. Diagnosis and treatment remain controversial, mainly because of its unusual presentation. The aim of this study was to report the outcomes of open treatment of eight rare cases and to evaluate our experiences in managing this condition.
PATIENTS AND METHODS: We performed a retrospective and descriptive study about operated patients for Spigelian hernia in our department of surgery between 2002 and 2016.
RESULTS: Eight patients were enrolled. The mean age was 52.25 years. There was a female predominance. All cases presented hernia risk factors. A painful abdominal mass presented the reason for consultation in four cases. Two of our patients had an associated inguinal hernia and one other had an umbilical hernia. In three cases, the hernia was strangulated. The diagnosis was confirmed by clinical examination in two cases and using radiological examinations in six cases. The content was a small bowel in four cases, epiploic in three cases, and colic in one case. A sublay mesh repair was performed in five cases and a primary suture in three cases. No recurrences were detected after 2 years of follow-up.
CONCLUSION: Spigelian hernia is underestimated. Open sublay mesh repair is feasible and safe. It ensure a great short and long term results. The open approach is feasible and safe to treat this condition.

| Introduction|| |
Spigelia More Detailsn hernias account about 0.1%–2% of all abdominal wall hernias. They are asymptomatic in 90% of cases. Clinical signs are nonspecific and dominated by a vague abdominal pain associated or not with an abdominal mass. Evolution is frequently marked by severe complications such as incarceration or strangulation. Treatment is a surgical repair. The aim of this study was to report the outcomes of open treatment of eight rare cases and to evaluate our experiences in managing this condition.
| Patients And Methods|| |
We performed a retrospective study of all patients diagnosed and treated for Spigelian hernia in our surgery department in Mahdia between 2002 and 2016. We analyzed sociodemographic characteristics, history, clinical presentation, complementary examinations, emergency or elective surgical procedures, postoperative complications, and recurrence.

Between January 2002 and December 2016, 13 patients were admitted with a suspicion of a Spigelian hernia, of which 5 were falsely diagnosed. Then, only eight patients met the inclusion criteria. The mean age was 52.25 years (46–72). There was a female predominance with a sex ratio male: female = 0.33. All cases presented hernia risk factors (6 multiparous, 4 obese, chronic bronchopathy, and median laparotomy) [Table 1]. Clinically, a painful abdominal mass [Figure 1] was the reason for consultation in four cases. The hernia was right sided in seven cases, left side in one case, and no bilateral hernia founded. Two of our patients had an associated inguinal hernia and one other had an umbilical hernia. In three cases, the hernia was complicated by strangulation. The diagnosis was confirmed by clinical examination in two cases, abdominal ultrasound [Figure 2] associated with computed tomography (CT) in two cases, and abdominal CT in four cases [Figure 3]. Surgery was performed under general anesthesia. An elective incision was used in all cases. The hernia sac was opened, explored, and resected in all cases [Figure 4]. The hernia content was a small bowel in four cases, epiploic in three cases, and colic in one case. The hernia orifice was <3 cm in five cases. The median size was 3.6 cm (range, 1–10). A retromuscular sublay mesh (15 cm × 8 cm) repair was performed in five cases. The mesh was fixed using an absorbable suture. A primary suture was made in the three cases complicated by strangulation with suffering small bowel content. We used a nonabsorbable suture. The median operative time was 42 min (range, 35–50), and the median hospital stay was 2.75 days (range, 2–6). All patients were followed up postoperatively and regularly exanimated at the outpatient clinic. No recurrence was detected with a median follow-up of 2 years (range, 1–5).

| Discussion|| |
The hernia of Spieghel does not fail due to its reputation of a rare hernia by the existence of only eight cases in our service during a study spread over 15 years. However, in the literature, some authors report a larger number of patients. Larson in the United States during 21 years has collected 81 cases, and Moles estimated the number of cases in the Spanish literature until 2003–162 cases. This type of hernia was described for the first time by Adriaan van den Spieghel, surgeon and anatomist (1578–1625). It is located at the junction between the rectus muscle fascia and the lateral muscles of the abdomen. Spigelian herina is the protrusion of preperitoneal fat, peritoneal sac, or organ(s) through a congenital or acquired defect in the spigelian aponeurosis. Our results are similar to many others in the world literature where this pathology is described as occurring from the fifth decade., Moreno-Egea found an average age of 60 years. Many cases have been described in children with a congenital defect in the Spieghel line. Risk factors were the weakness of the abdominal wall or the increase of intra-abdominal pressure, all associated with an anatomical predisposition of the Spieghel line. These include obesity, chronic obstructive pulmonary disease, previous surgery, or abdominal trauma. According to Moles, the retraction of a scar behind an area of weakness increases the risk of hernia. He found these factors in 100 patients of 162 patients. There was a surgical history for 39%, obesity 21%, and multiparity 14%. All patients of Moreno–Egea present these factors, six cases with surgical history, six cases of abdominal trauma, six cases of obesity, and the remainder were Chronic Obstructive Pulmonay Disease (COPD). In the literature, these risk factors were reported with various degrees. This hernia can occur at any point of the Spieghel line, below which all the aponeurotic layers are reflected in front of the rectus muscle. They are located infraumbilically in 90% of cases. Clinical manifestations are not specific. They depend on hernia contents. According to Mathonnet, 90% would be asymptomatic. The most frequent symptomatology is an abdominal mass that can be painful. The pain can be explained by the narrowness of the hernia orifice. Strangulation rate is estimated as 40% according to Moles. The diagnosis is usually made by abdominal examination. However, if the Spieghel hernia is small and covered by the aponeurosis of the external oblique muscle or if the patient is obese the diagnosis becomes difficult. In addition, a lower localization could be misdiagnosed as an inguinal hernia. It is recommended to perform an ultrasound or better a CT to diagnose this disease [Figure 2] and [Figure 3].,, Sometimes, laparoscopy is a promising diagnostic and therapeutic alternative. The surgical treatment can be suture closure, muscle plasty, or mesh repair with good results.,, The open approach ensures good results in terms of morbidity and recurrence but usually requires longer hospitalization and wide dissection.,, In 1992, Carter published the first laparoscopic repair of a Spigelian hernia. This alternative reduces significantly the hospital delay (5.2 days in open approach vs. 1 day in TEP approach vs. 1.4 days in intraperitoneal laparoscopic repair). However, it has a specific complication such as bowel perforation and trocar site complications. On the other side, the completely extraperitoneal laparoscopic approach could avoid these disadvantages and allow repair of the defect at its origin in the abdominal wall.,
