Scrotal and penile edema is a noninfectious complication of peritoneal dialysis (PD). A tear in the Spigelian fascia is occasionally recognized as a Spigelian hernia. However, there is no documented evidence that this is a contributing factor for scrotal edema in individuals undergoing PD. We encountered a case of scrotal edema in a patient undergoing PD due to bilateral metachronous tears in the Spigelian fascia, which was successfully treated through surgical repair. A 20-year-old man with end-stage kidney disease due to Alport syndrome underwent PD. Eight months after induction of PD, he heard a rupture sound in the left inguinal region after coughing and developed genital edema. A computed tomography scan showed a tear in the left Spigelian fascia. Surgical repair was successful and there was no recurrence after PD was resumed. Seven months after surgery, he heard a rupture sound in the right inguinal region after coughing and developed genital edema. A computed tomography scan showed a tear in the right Spigelian fascia. Surgical repair was successful and there has been no recurrence since. It is important to recognize that the development of scrotal edema in a patient undergoing PD may be indicative of a tear in the Spigelian fascia.

BACKGROUND: Spigelian hernias are among the rare primary ventral hernias. Diagnosis is often difficult, as many cases are asymptomatic. Spigelian and inguinal hernias are usually considered separately in current scientific literature. With this case series, we want to illustrate a possible relationship between the neighboring hernia types.
METHODS: In this article, we report on a case series of Spigelian hernias that were operated on in five hernia centers in the period from January 1st, 2021 to October 31st, 2023. We have summarized all patient characteristics with previous operations and the result of the secondary operation.
RESULTS: We report a case series with 24 Spigelian hernias, 15 of which have a connection to previous inguinal hernias. In these cases, however, it is not certain whether these are primarily overlooked or occult hernias or whether these Spigelian hernias have arisen secondarily, as a result of previous hernia surgery. With this case series, we would like to point out a possible connection between Spigelian hernia and inguinal hernia. Further studies are needed to shed more light on this entity and explain its genesis.

BACKGROUND: Spigelian hernia is a rare type of abdominal wall hernias which are often diagnosed when incarcerated. These hernias typically develop at the crossing point of the arcuate line and lateral portion of rectus abdominis muscle.
METHODS: We present the case of a 44-year-old female patient admitted to our surgery unit for a painful lump in her right mesogastrium. Incarcerated atypical hernia in the right mesogastrium was suspected based on completed imaging assessments. Spigelian hernia was confirmed by preoperative findings. Interestingly, the patient applied interferon (multiple sclerosis therapy) at the site of the lump, which is why the diagnosis of lipodystrophy had been considered.
CONCLUSIONS: In general, the diagnosis of Spigelian hernia is difficult. From the anatomical point of view the clinical finding is not always specific. The risk of incarceration is relatively high, and thus even clinically silent findings are indicated for surgery.

UNASSIGNED: Spigelian hernias are rare, constituting about 1-2 % of all abdominal wall hernias. They present clinically significant challenges due to their potential for incarceration and strangulation. This case report highlights a unique presentation of a Spigelian hernia involving sigmoid colon strangulation, emphasizing the critical need for awareness and timely intervention.
METHODS: A 60-year-old female with hypertension and diabetes presented with severe left abdominal pain, nausea, and vomiting. Examination revealed leukocytosis, neutrophilia, and signs of acute abdomen. CT imaging showed a complicated left lateral abdominal wall hernia containing the sigmoid colon. Surgical intervention included sigmoidectomy with colorectal anastomosis and hernia repair. Postoperative recovery was successful with subsequent elective ileostomy reversal.
UNASSIGNED: The rarity of Spigelian hernias and their atypical presentations can complicate diagnosis and management. This case was particularly challenging due to the strangulation of the sigmoid colon within the hernial sac. Surgical management was necessary to address the incarcerated bowel segment and prevent further complications. This case underscores the utility of CT scans in diagnosing complex cases and guiding surgical strategy.
CONCLUSIONS: Despite their rarity, Spigelian hernias carry significant risks of strangulation. Prompt diagnosis and treatment are essential to avoid severe complications. This case highlights the importance of including Spigelian hernia in the differential diagnosis for acute abdominal symptoms, especially when they are nonspecific.

A 49-year-old woman with a complicated hernia presentation, including direct and indirect inguinal hernias, Spigelian hernias, and Pantaloon hernias, is presented in the case report. The diagnosis was verified by a comprehensive physical examination and imaging, which resulted in a Lichtenstein operation for repair. The surgical procedure for hernia comprised of painstaking dissection, reduction of the hernia sac, and implantation of a prosthetic mesh. The instance emphasizes the value of individualized treatment programs and draws attention to the intricate anatomical details of hernia surgery. Analyzing situations that are similar to one another highlights the necessity of customized strategies to improve patient outcomes.

BACKGROUND: Spigelian hernia is a rare entity, with higher improbability of acute appendicitis within it.
METHODS: A 75-year-old female with a 30-year evolution hernia, abdominal pain, and fever of 1 week of onset, in whom was found an acute appendicitis within a Spigelian hernia.
CONCLUSIONS: Spigelian hernia comprises 0.12-2% of all abdominal hernias. Presurgical diagnosis is stablished only in 50% of cases, with an hernial ring less than 2 cm and hidden localization. There isn\'t statistics of this complication because of the lack of case reports.
UNASSIGNED: La hernia de Spiegel es una afección infrecuente, con una improbabilidad aún mayor de apendicitis aguda en su interior.
UNASSIGNED: Mujer de 75 años que acude con una hernia de 30 años, dolor abdominal y fiebre de 1 semana de inicio, en quien se encontró apendicitis aguda dentro de una hernia de Spiegel.
UNASSIGNED: La hernia de Spiegel comprende el 0.12-2% de las hernias abdominales. El diagnóstico prequirúrgico se ha logra en el 50% de los casos, con defecto menor de 2 cm y de localización oculta. No existe estadística de esta complicación debido a la escasez de casos reportados.

BACKGROUND: Compared to other types of abdominal protrusions, Spigelian hernias are not very common. In prosthetic repair of abdominal protrusions, mesh fixation and defect overlap are an open issue, as they are a source of complications. A newly developed tentacle-shaped mesh has been used to ensure a fixation-free repair with a broader defect overlap in the repair of abdominal hernias. This study describes the long-term results of a fixation-free repair of Spigelian hernias carried out with a tentacle mesh.
METHODS: A proprietary mesh composed of a central body with integrated radiating arms was used for repairing Spigelian hernias in 54 patients. The implant was positioned in preperitoneal sublay, and the straps were delivered across the abdominal musculature with a needle passer, and then, after fascia closure, cut short in the subcutaneous layer.
RESULTS: The friction of the straps passing through the abdominal wall served to hold the mesh in place, guaranteeing a wide overlap over the defect without fixation. In a long-term follow-up of 6 to 84 months (mean 64 months), a very low rate of complications occurred, but no recurrence was reported.
CONCLUSIONS: The tentacle strap system of the prosthesis allowed for an easy, fast and safe fixation-free placement granting a wide overlap, avoiding intraoperative complications. Greatly reduced pain and a negligible amount of postoperative complications characterized the postoperative outcome.

Blunt abdominal trauma due to bicycle accident is a common occurrence in the pediatric population; however, traumatic abdominal wall hernia as the result of blunt trauma is a rare presentation. Abdominal wall injuries can be isolated or associated with multiple intra-abdominal pathologies. A high index of suspicion is essential for prompt intervention, especially when there is concurrent intra-abdominal pathology. We present a case of a traumatic spigelian hernia in a pediatric patient following a handlebar injury with the intraoperative discovery of a bucket-handle type mesenteric injury to the jejunum.

Spigelian hernias (SpH) belong to the group of eponymous abdominal wall hernias. Major reasons for diagnostic difficulties are its low incidence reaching maximum 2% of abdominal wall hernias, a specific anatomical localization with intact external oblique aponeurosis covering the hernia sac and non-constant clinical presentation.
A literature review was completed to summarize current knowledge on surgical treatment options and results.
SpH presents a high incarceration risk and therefore should be operated upon even if the patient is asymptomatic. Both laparoscopic and open repair approaches are validated by current guidelines with lesser postoperative complications and shorter hospital stay in favour of minimally invasive surgery, regardless of the technique used. Overall recurrence rate is very low.
All diagnosed SpH should be planned for elective operation to prevent strangulated hernia and, therefore emergency surgery. Both open and laparoscopic SpH treatment can be safely performed, depending on surgeon\'s experience. In most cases, a mesh repair is generally advised.
