F1000Research 2024, 13 :1352 ( https://doi.org/10.12688/f1000research.157529.1 ) First published: 11 Nov 2024, 13 :1352 ( https://doi.org/10.12688/f1000research.157529.1 ) Latest published: 11 Nov 2024, 13 :1352 ( https://doi.org/10.12688/f1000research.157529.1 ) Introduction Spigelian hernia is a rare form of ventral hernia. It involves the protrusion of preperitoneal fat, peritoneal sac, or intra-abdominal organs through a defect in the Spigelian aponeurosis, which lies between the rectus abdominis muscle medially and the semilunar line laterally. The Spigelian aponeurosis, formed by the fusion of the internal oblique and transversus abdominis aponeuroses, constitutes a structurally vulnerable region of the abdominal wall, predisposing it to herniation under conditions of elevated intra-abdominal pressure. Predisposing factors include obesity, chronic obstructive pulmonary disease (COPD), prior abdominal surgery, and trauma. While most Spigelian hernias are acquired, congenital forms have also been reported, potentially due to embryological defects in the development of the abdominal musculature. 1 ’ Spigelian hernias are challenging to diagnose clinically because the defect is often masked by the overlying external oblique aponeurosis, making it difficult to detect on physical examination. As a result, patients may present acutely with complications such as incarceration, strangulation, or bowel obstruction. Given the high risk of these complications, Spigelian hernias are not suitable for conservative management, and surgical intervention is the recommended treatment in both elective and emergency cases. 2 This case report presents a patient with an obstructed right lower quadrant Spigelian hernia, as well as a left-sided Spigelian hernia accompanied by a non-complicated Meckel’s diverticulum, which was successfully managed through open laparotomy. Case presentation A 72-year-old female with a history of bronchial asthma, obesity, and left-sided breast cancer treated with mastectomy, currently on Anastrozole therapy, in addition to anxiety and depression history, presented to the emergency department with progressively worsening right iliac fossa pain over the past two days. The pain had been intermittent for two months. She also reported the presence of a palpable mass in the right lower quadrant, accompanied by nausea and multiple episodes of vomiting the previous night. Her bowel habits were normal, and there was no per-rectal bleeding. On physical examination, significant tenderness was noted in the right iliac fossa, and a firm mass was palpated along the lateral border of the rectus abdominis muscle, approximately midway between the umbilicus and the symphysis pubis. The mass became more prominent when the patient was examined in a standing position and was associated with voluntary guarding. Symptomatic relief was provided with analgesics and antiemetics. Laboratory investigations revealed a white cell count of 9,700 WBC/μL, hemoglobin of 146 g/dL, platelet count of 366,000 platelets/μL. A contrast-enhanced CT scan of the abdomen and pelvis ( Figure 1 ) identified a right-sided Spigelian hernia containing small bowel loops, with proximal small bowel dilatation suggestive of developing obstruction, with incidental findings included a simple liver cyst and a bulky uterus. After discussing the surgical options, the patient consented to proceed with an open laparotomy. Figure 1. Right spigelian hernia most prominent in image C and small spigelian defect noted at the left side without hernia sac noted in image B. Preoperative preparation involved keeping the patient nil by mouth (NBM), administering intravenous fluids (IVF), obtaining an electrocardiogram (ECG), scheduling the operating room, securing informed consent, performing a blood group and save, administering symptomatic medications, and conducting an anesthetic review. The procedure was performed under general and local anesthesia, with prophylactic intravenous antibiotics administered within one hour prior to the incision. During surgery, a lower midline incision was made. A Meckel’s diverticulum was identified approximately 20 cm from the ileocecal valve. Although bruised, it was not inflamed, so it was left intact to avoid contamination of the mesh with bowel flora. Bilateral hernial defects were observed, with the right hernia being larger than the left. Both defects were located adjacent to the lateral rectus sheath, and the right Spigelian hernia contained small bowel loops and preperitoneal fat. The small bowel loops were examined up to the duodenojejunal (DJ) junction, with no abnormalities detected. The right Spigelian hernial sac was opened, and its contents were inspected. The hernia defect was closed from the peritoneal side using 2-0 Vicryl sutures, and a 6×11 cm Prolene mesh was placed in a sublay position deep to the rectus muscle. The left Spigelian hernia was repaired using primary suture closure with 2-0 Prolene. A transversus abdominis plane (TAP) block was administered by the anesthetist. Postoperatively, the patient was advised to resume oral intake and continue antibiotic therapy for 48 hours ( Figure 2 ). Figure 2. Sublay Mesh Repair (Retromuscular/Subfascial) : The mesh is placed between the right rectus abdominis muscle and posterior rectus sheath. On postoperative day 1, the patient experienced moderate abdominal pain, multiple episodes of greenish vomiting, with absence of bowel movements, abdominal bloating, and reduced urine output of less than 30 mL/hour. Intravenous fluids were administered, and a nasogastric tube (NGT) and urinary catheter were inserted. Oral intake was limited to sips of water. A chest and abdominal X-ray revealed atelectasis and dilated small bowel loops ( Figure 3 ). Figure 3. X-ray chest and abdomen showing atelctasis with dilated small bowel loops. By postoperative day 2, the patient’s symptoms persisted, and blood tests showed elevated inflammatory markers: CRP of 246 mg/L, WCC of 11.5 × 10 9 /L, hemoglobin of 122 g/L, and platelet count of 358 × 10 9 /L. Due to concern for an intraperitoneal collection or bowel perforation, a CT abdomen and pelvis (CTAP) was performed, revealing multiple distended small bowel loops with air-fluid levels, consistent with postoperative ileus ( Figure 4 ). Figure 4. multiple loops of distended small intestine which contain an air-fluid level, represented post operative ileus. By postoperative day 3, the patient passed a bowel movement and began mobilizing with physiotherapy assistance. Initially, she did not meet the physiotherapy assessment criteria, but her physical performance gradually improved in the following days. By postoperative day 6, she was able to mobilize independently and was discharged home. A follow-up appointment was scheduled for six weeks later. Discussion Spigelian hernia is a rare abdominal wall defect, with its incidence peaking between the 4th and 7th decades of life. A slight female predilection has been noted, with a male-to-female ratio of 1:1.183. The hernia occurs within the “Spigelian belt,” a 6 cm wide zone along the Spigelian line extending caudally from the umbilicus to the inferior epigastric vessels. Based on the relationship to these vessels, Spigelian hernias are classified into two types: high hernias (cranial to the vessels) and low hernias (caudal to the vessels, within Hesselbach’s triangle). 3 Several theories explain the etiology of Spigelian hernias. Cooper’s vascular-nervous theory suggests weakening of the Spigelian belt due to the deep iliac branch of the inferior epigastric vessels penetrating the aponeurosis. Zimmerman’s musculo-aponeurotic fasciculation theory is more widely accepted, proposing that infiltration of preperitoneal fat weakens the deep fibrous musculature, predisposing it to herniation ( Figure 5 ). Other theories, such as the embryologic transition theory and Watson and Iason’s theory, implicate areas of lower resistance between developing abdominal wall muscles and weaknesses at the junction of the semilunar line and arcuate line, respectively. Risk factors for Spigelian hernia include obesity, chronic obstructive pulmonary disease (COPD), prior abdominal surgery, trauma, and conditions increasing intra-abdominal pressure. 4 Figure 5. Rendering of a Spigelian hernia through the various tissue layers. A) External oblique. B) Internal oblique. C) Transverse abdominis. D) Hernia sac with contents. E) Spigelian fascia. F) Rectus abdominis. Clinically, Spigelian hernias often evade early detection due to their deep location beneath the external oblique aponeurosis, making physical examination findings subtle or absent. Early symptoms can be nonspecific, ranging from vague abdominal discomfort to a palpable lump. However, the risk of complications, including incarceration (reported in 24–27% of cases) and strangulation (2–14%), is significant. These risks arise from the formation of a “rigid neck” in the hernial sac, particularly due to the Spigelian fascia’s fibrous bands. In this patient, morbid obesity and chronic cough associated with asthma likely contributed to the hernia formation, and she presented with a tender right iliac fossa mass, which was confirmed on CT imaging to be an obstructed Spigelian hernia, a situation warranting urgent surgical intervention. 5 Imaging is critical in diagnosing Spigelian hernias, especially given their frequent misdiagnosis in early stages. Computed tomography (CT) is the preferred modality for identifying the defect, its size, and contents, for appropriate surgical planning. In this case, CT identified the hernia and confirmed small bowel involvement, indicating impending obstruction and urgent surgical management. While physical examination alone often fails to detect Spigelian hernias, imaging techniques such as ultrasound and CT are crucial for early diagnosis and surgical planning. 6 Surgical intervention is the definitive treatment for Spigelian hernia, with both open and laparoscopic approaches offering these options based on patient factors, hernia characteristics, available resources, and the surgeon’s expertise. Laparoscopic repair is gaining popularity due to its advantages of better bilateral visualization, detection of contralateral defects, and shorter recovery times. However, open repair offers superior intra-operative direct visualization and dissection, particularly for larger or more complex hernias. Both approaches aim for complete defect closure, typically reinforced with mesh to reduce the risk of hernia recurrence. 7 Mesh reinforcement is strongly recommended in both open and laparoscopic spigelian hernia repairs, as outlined by the European Hernia Society (EHS) guidelines. Various mesh techniques exist, each selected based on the hernia size and complexity 8 : 1. Primary Suture Repair : Suitable for small hernias, it involves closing the defect with non-absorbable sutures. However, it carries a higher recurrence risk for larger hernias. 2. Onlay Mesh Repair : A synthetic mesh is placed on the anterior rectus sheath to reinforce the defect, but it may cause complications such as seroma or wound infection. 3. Sublay Mesh Repair (Retromuscular/Subfascial) : Mesh is placed between the rectus muscle and posterior rectus sheath. This technique provides robust support with fewer complications, making it ideal for complex or recurrent hernias. 4. Inlay Mesh Repair : Mesh is positioned directly within the defect, offering simplicity but a higher recurrence risk due to incomplete coverage. 5. Preperitoneal Mesh Repair : Mesh placement in the preperitoneal space reduces mesh-related complications and is less invasive but can be technically demanding. 6. Component Separation Technique : This involves mobilizing abdominal muscles to close large defects without tension, potentially with mesh reinforcement. It allows closure of large defects but is more invasive and associated with higher wound complication risks. In this case, the patient underwent open sublay mesh repair for the right-sided Spigelian hernia, while the left-sided hernia was repaired with primary sutures. This approach allowed for thorough intraoperative inspection of the hernia contents and effective defect closure. Although the recovery was prolonged by postoperative ileus, the patient showed gradual improvement and was successfully discharged. Ultimately, the choice between open and laparoscopic repair depends on the hernia’s complexity and the surgeon’s expertise. Both approaches, when paired with mesh reinforcement, offer effective and durable repair modalities, with laparoscopic techniques gaining favor for their minimally invasive nature and faster recovery times. Conclusion Spigelian hernia often presents a diagnostic challenge due to its lack of distinct physical findings, leading to frequent delays in diagnosis. A high index of clinical suspicion is essential, given the potential for complications such as bowel obstruction and strangulation. Fortunately, in this case, the patient presented with clear symptoms, allowing for timely surgical intervention and successful repair. Computed tomography (CT) imaging played a crucial role in confirming the diagnosis, and in instances where imaging is inconclusive, open laparotomy provides superior visualization and access to the peritoneal cavity, facilitating thorough inspection, especially in complex cases involving the small bowel and Meckel’s diverticulum. Surgical intervention remains the cornerstone of treatment for Spigelian hernia, as supported by the literature. In this case, open repair with a Sublay Mesh technique was performed, placing the mesh between the rectus abdominis muscle and the posterior rectus sheath to reinforce the defect. While Spigelian hernias are rare, their high risk for acute complications necessitates that they remain a differential diagnosis in patients presenting with abdominal pain. Early recognition and prompt surgical management are key to preventing adverse outcomes.

Continue reading READ ALL The case is well organized and complies with the standards for case reports. Nonetheless, I like to emphasize some places where I believe enhancements are essential for optimal comprehension of the case and for educational objectives. Certain grammatical errors in the text and image labels require correction. The authors stated in the abstract that the mesh was placed intraperitoneally, which contradicts the case description. In the case presentation, it is essential to comprehend the history of reducibility concerning the right swelling during the last two months of intermittent abdominal pain. This information would assist in determining whether we were addressing an incarcerated hernia or a reducible hernia. Furthermore, the narrative fails to address the reducibility of the mass during the two days of exacerbated discomfort, prompting me to conclude that it was irreducible. The physical examination lacks details regarding the left abdominal swelling, if present, and does not provide information on the assessment of the remaining abdominal quadrants, as bowel sounds are not noted as a significant indicator of intestinal obstruction. During the research, I noted that an accessible and effective method, such as abdominopelvic ultrasonography, was not employed (for what reason?). The surgical treatment does not clarify whether the Meckel’s diverticulum was included in the hernia sac; it is noted that the diverticulum exhibited bruising (what was the cause of this?). A visual representation is absent; however, it would benefit the surgical community, particularly since the decision was made not to resect the diverticulum, acknowledging that potential complications such as inflammation, bleeding, and obstruction may arise in the future. Due to the patient's paralytic ileus in the postoperative phase, a serum electrolyte test may be conducted, as it plays a crucial part in the condition's pathogenesis. This case report pertains to Spigelian hernias with Meckel's diverticulum. Nonetheless, I did not locate any information pertaining to the correlation and care of Meckel's diverticulum and hernias during the discussion of the case. Aside from two references, the remainder are over a decade old. Conclusions: In addition to these particulars, the case report is highly engaging and informative for the entire medical community, particularly the surgical sector. Is the background of the case’s history and progression described in sufficient detail? Yes Are enough details provided of any physical examination and diagnostic tests, treatment given and outcomes? Yes Is sufficient discussion included of the importance of the findings and their relevance to future understanding of disease processes, diagnosis or treatment? Partly Is the case presented with sufficient detail to be useful for other practitioners? Partly Competing Interests: No competing interests were disclosed. Reviewer Expertise: As a general surgeon, my scope of expertise encompasses a wide range of procedures, particularly abdominal surgery, with a focus on abdominal wall hernias, which represent one of the most prevalent diseases in our specialty globally. I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard.
