Congenital spigelian hernias and cryptorchidism

Purpose

Spigelian hernias in childhood are rare. Only 24 infants in the English literature have been identified to have spigelian hernias, and 12 of these have been associated with cryptorchidism. Spigelian hernias are more commonly seen in the adult population and are considered to be acquired because they are typically associated with trauma or other etiologies of increased intraabdominal pressure. In the infant however, the etiology remains unclear, but a congenital defect in abdominal wall development is suspected.

Methods

We discuss the presentation and treatment of 4 additional patients with spigelian hernias (2 siblings included) associated with cryptorchidism.

Results

The hernias occurred within the well-described spigelian hernia belt in the semilunar line at the level of the semicircular fold of Douglas. Of the 6 repaired spigelian hernias, 5 were closed primarily with absorbable suture similar to previously reported cases; the sixth hernia required a patch closure because of its large size. All cryptorchid testes (7) were repaired in single-stage orchiopexies.

Conclusions

Spigelian hernias are rare entities in infants. We present 4 new cases of spigelian hernias associated with cryptorchidism and, with previously reported cases, discuss the probability of a congenital origin of these hernias in infants.     

Bilateral lumbar hernia associated with abdominal hernias. A case report.

Multiple abdominal hernias constitute a quite rare event in surgical practice. Lumbar hernias are even rarer and, to our knowledge, this is the first report in the English literature of its association with abdominal hernias. A case of multiple abdominal hernias, namely an epigastric hernia and a left inguinal hernia together with a bilateral lumbar hernia in a 65-year-old man attending the Out-patient department of Hoima Hospital-Uganda is described. A one-stage repair under local anaesthesia was chosen. The patient recovered uneventfully and no recurrence was noted at 1 year follow-up. This case report supports that a "one-stage" procedure under local anaesthesia can be appropriate as surgical treatment of multiple abdominal hernias when abdominal defects are of a small size. A minimal surgical approach to lumbar hernias seems also suitable when transverse muscle aponeurosis defect can be carefully repaired and covered with adjacent muscles.     

Lateral ventral (spigelian) hernias in infants and children.

Lateral ventral hernias are found in the spigelian fascia lateral to the junction of the arcuate and semilunar lines and below the level of the umbilicus. Three cases are reported in infants and children. Diagnosis depends on finding an unusual mass on the anterior abdominal wall and palpation of the rim of the hernia defect upon reduction of the mass. A spigelian hernia may be misdiagnosed easily if the examiner is unaware that it can occur in childhood. The edge of the defect must be outlined while the child is straining, prior to induction of anesthesia, as the rim may be difficult to find when the patient is asleep.     

Laparoscopic repair of incarcerated low spigelian hernia with transperitoneal PTFE DualMesh

There are different types of hernias that can develop at certain sites in the abdominal wall. Spigelian hernia (SH) is a protrusion of abdominal contents through a defect in the spigelian aponeurosis, in proximity to the external margin of the rectus muscle. Usually, abdominal wall hernia sac contains the omentum but may also contain small intestine that might become trapped in the hernia. When ischemia of herniated contents is suspected, urgent surgical treatment is advocated. Elective laparoscopic repair of SH is still under discussion. However, a recent randomized study comparing open and laparoscopic repair as elective treatment suggested that extraperitoneal laparoscopic repair is the technique that offers best results for the patients. Recent development of new biologic materials and technologies in laparoscopy has led to improved results. We report the successful repair of incarcerated low SH that was successfully managed by urgent laparoscopic intraperitoneal onlay polytetrafluoroethylene mesh hernioplasty.     

Minimally Invasive Spigelian Hernia Repair

Introduction:

Spigelian hernia is an uncommon ventral hernia characterized by a defect in the linea semilunaris. Repair of spigelian hernia has traditionally been accomplished via an open transverse incision and primary repair. The purpose of this article is to present 2 case reports of incarcerated spigelian hernia that were successfully repaired laparoscopically using Gortex mesh and to present a review of the literature regarding laparoscopic repair of spigelian hernias.

Methods:

Retrospective chart review and Medline literature search.

Results:

Two patients underwent laparoscopic mesh repair of incarcerated spigelian hernias. Both were started on a regular diet on postoperative day 1 and discharged on postoperative days 2 and 3. One patient developed a seroma that resolved without intervention. There was complete resolution of preoperative symptoms at the 12-month follow-up.

Conclusion:

Minimally invasive repair of spigelian hernias is an alternative to the traditional open surgical technique. Further studies are needed to directly compare the open and the laparoscopic repair.     

Laparoscopic repair of a spigelian hernia: a case report and literature review.

BACKGROUND: We present a case in which laparoscopy was both diagnostic and therapeutic in a patient with a spigelian hernia. CASE REPORT: A 35-year-old man was referred to the General Surgery Service for evaluation of right lower quadrant abdominal pain of approximately 6 months. The pain was not disabling but was a constant discomfort. The patient did not have any significant past medical or surgical history, and the physical examination was significant only for an area of focal tenderness in the right lower quadrant. Ultrasound and CT scans of the patient's abdomen were unremarkable. A laparoscopic exploration of the area revealed a defect in the area of semilunar and semicircular lines consistent with a spigelian hernia. The patient underwent a laparoscopic herniorrhaphy with placement of a polypropylene mesh. CONCLUSION: This case illustrates the role of laparoscopy in the diagnosis and treatment of spigelian hernias.     

Laparoscopic repair of incidentally found Spigelian hernia

Background and Objectives:

A Spigelian hernia is a rare type of hernia that occurs through a defect in the anterior abdominal wall adjacent to the linea semilunaris. Estimation of its incidence has been reported as 0.12% of all abdominal wall hernias. Traditionally, the method of repair has been an open approach. Herein, we discuss a series of laparoscopic repairs.

Methods:

Case series and review of the literature.

Cases:

Three patients are presented. All were evaluated and taken to surgery initially for a different disease process, and all were incidentally found to have a spigelian hernia. These patients underwent laparoscopic repair of their hernias; 2 were repaired intraperitoneally and one was repaired totally extraperitoneally. Two patients initially underwent a mesh repair, while the third had an attempted primary repair.

Conclusions:

There is evidence that supports the use of laparoscopy for both diagnosis and repair of spigelian hernias. There are also reports of successful repairs both primarily and with mesh. In our experience with the preceding 3 patients, we found that laparoscopic repair of incidentally discovered spigelian hernias is a viable option, and we also found that implantation of mesh, when possible, resulted in satisfactory results and no recurrence.     

Right lower quadrant abdominal pain due to appendicitis and an incarcerated spigelian hernia

Spigelian hernias are uncommon and difficult to diagnose because of their location in the aponeurosis in the anterior abdominal wall. When they occur on the right side, the symptoms can include nonspecific abdominal pain mimicking appendicitis. We present an adult with right lower quadrant abdominal pain due to an incarcerated spigelian hernia and acute appendicitis. Early recognition and prompt surgical treatment were important to the successful treatment of our patient.     

Management of Spigelian hernia caused by necrobiotic fibroma of the uterus in a pregnant woman

INTRODUCTIONSpigelian hernias are a rare type of hernia through the Spigelian aponeurosis. Spigelian hernias are very uncommon and constitute only 0.12% of all abdominal wall hernias. These hernias are located in the aponeurosis of the internal oblique muscle and transverse abdominal muscle.PRESENTATION OF CASEA 30-year-old woman at 28 weeks’ gestation was admitted to the obstetrics department due to pain and swelling in the anterior abdominal right region. On inspection, we suspected either a lipoma, a spontaneous hematoma, a tumor of the abdominal wall, or a Spigelian hernia. A Doppler USG and abdominal and pelvic Magnetic Resonance Imaging revealed necrobiotic fibroma of the uterus in Spigelian hernia. The patient was started on dual analgesic and corticotherapy. Overall, the patient improved one week after the acute episode and had no further pain during her gynecologic follow-up.DISCUSSIONWe have reported a first case of Spigelian hernia that was complicated by uterine fibroid. The clinical presentation varies, depending on the contents of the hernial sac and the degree of herniation. MRI is the preferred method for accurately identifying masses of the abdominal wall. Our treatment options were based on the extent of the acute-phase reaction and the venous thrombosis.CONCLUSIONIt is important to differentiate this rare Spigelian hernia from other hernias as the treatment for this hernia is medical rather than surgical. Before the final choice of treatment is made, digestive surgeons should bear this rare hernia in mind.     

Grynfelt hernia: case report and literature review

Back lumbar hernia is a rare abdominal wall defect that usually presents spontaneously after trauma or lumbar surgery or, less frequently, during infancy (congenital). Few reports have been published in the literature describing primary lumbar hernia. A general surgeon will have the opportunity to repair only one or a few lumbar hernia cases in his/her lifetime. We report a case of a healthy 50-year-old man, with no previous surgeries or history of trauma, who presented to the outpatient department with abdominal discomfort, pain, and a sensation of a growing mass on his lower left back for 4 years. CT scan of the abdomen showed a mass in the left posterolateral abdominal wall. Specifically, a herniation of retroperitoneal fat between the erector spinae muscle group and internal oblique muscles through aponeurosis of the transversalis muscle (Grynfeltt hernia). The patient underwent a small lumbotomy, polypropylene mesh was placed and he recovered well. Although many techniques have been described for the surgical management of such hernias, none of them can be recommended as the preferred method. Our impression, however, is that the open approach, with a small lumbotomy, seems to be easy, safe and presents good postoperative recovery.     

Symptomatic linea arcuata hernia

Hernias are often associated with congenital defects or incisional breakdown. Even though most of the linea arcuata hernias are asymptomatic, we present a rare case of a symptomatic linea arcuata hernia with associated internal herniation of the colon sigmoideum in a woman without previous abdominal surgery.     

Spigelian hernia presenting as an incarcerated incisional hernia

Summary Spigelian hernia, first described at the 18th century, is a rare ventral abdominal hernia occuring through the spigelian fascia. The diagnosis is difficult especially when there is no palpable mass. The case presented here had a spigelian hernia mimicking an incarcerated incisional hernia. This patient had undergone an appendectomy through a right paramedian incision proviously. Three years later she was operated for a suspected incisional hernia. Exploration did not reveal any defects in the external oblique aponeurosis so no further exploration was done. Our operative findings showed also an intact external oblique aponeurosis but when incised a spigelian hernia was observed beneath this structure, which was repaired promptly. A high index of suspicision is necessary for diagnosis both pre and intraoperatively.     

Inguinal hernia repair with the peduncled fascial flap: a new surgical technique

Introduction  This paper presents a new surgical technique of inguinal hernia repair in which both crura of the aponeurosis of the external oblique abdominal muscle and transverse fascia were used for complex reconstruction of the entire musculopectineal hiatus. Material and methods  Between 2nd December 2003 and 29th April 2005, 250 patients (233 male and 17 female) underwent inguinal hernia repairs using our own technique. The inguinal canal was opened together with the posterior wall, dividing the transverse fascia into two flaps. The lower flap was inserted into the femoral opening and sewn to the pectineal ligament, whereas the upper flap with both crura of the aponeurosis of the external oblique abdominal muscle were used for three-fascia reconstruction of the posterior wall of the inguinal canal. The study group was randomly chosen from patients undergoing surgery due to inguinal hernias in our hospital. Procedures were carried out under subarachnoid anaesthesia; postoperative pain was treated with methamizol or ketoprofen. Patients were discharged 48 h after surgery. Results  The postoperative complications included one hernia recurrence and one testicular atrophy. The remaining complications were transient and included prolonged wound healing, transient skin hypoaesthesia around the wound or testis oedema. Conclusions  The technique used strengthens the musculopectineal hiatus, effectively preventing recurrences of inguinal as well as femoral hernias.     

Spigelian hernia repair as a day-case procedure

Purpose

Only a few series of patients with a spigelian hernia managed on an outpatient basis have been reported in the literature. The aim of this prospective study was to evaluate the results of the elective spigelian hernia repair as an ambulatory procedure.

Methods

From June 2007 to June 2010, 8 patients with 9 spigelian hernias were electively operated on under local anesthesia as a day case. Four patients had unilateral spigelian hernia, 1 had spigelian and inguinal on the same side, 1 had spigelian and epigastric, 1 had spigelian and umbilical, and 1 patient had bilateral spigelian and umbilical hernia. Spigelian hernia was managed by the “open preperitoneal flat mesh technique.” In patients with several ventral hernias at different sites, “the open preperitoneal flat mesh technique” was performed using one separate flat mesh for each of the hernias; for the patient with inguinal hernia, the Lichtenstein procedure was performed in addition.

Results

No complications and recurrences were recorded during a mean follow-up of 23.5 months (range: 11–35).

Conclusion

The elective spigelian hernia can be successfully repaired under local anesthesia as a day-case procedure. The “open preperitoneal flat mesh technique” provides excellent results under these conditions.     

Spigelian Hernia

We report on the evolution in concept and techniques that allowed us to improve the treatment of spigelian hernia, operable in day surgery in 90% of cases and through a preperitoneal and recently a preperitoneal and subfascial prosthetic repair (PHS). Background data. We propose an innovative use of the PHS mesh for spigelian hernia repair. With this new implementation, we confront the standard surgical technique and its postoperative period. Methods. From January 1992 to March 2004, we performed 2,500 hernia surgical operations, including 32 spigelian hernia repairs (1.3% of total case series). The first surgical approach used for 20 of these 32 patients (62.5% of total spigelian hernias), all electively operated on, was a classical preperitoneal repair (Wantz), performed when possible by size of defect and weight (Body Mass Index) of the patient, under local anesthesia and on a day-surgery basis. Our new modified technique takes place through the insertion of a PHS large-type mesh, whose bottom underlay portion lies flat in the preperitoneal space with the connector obliterating the hernial orifice and with the overlay portion lying on the internal oblique muscle, covered by the aponeurosis of the external oblique muscle. Results. Our modification to the classical technique consisted only in the application of a product, such as the PHS, in a hernia defect, which presented with an orifice of the size of the connector and, therefore, was easily repairable with the use of the PHS device. This approach is easier than the preperitoneal approach, its always suitable for local anaesthesia, and it gives a more comfortable postoperative period. The surgical approach may be performed completely in day surgery. Conclusions. We believe that spigelian hernia surgical repair should always be performed by means of a preperitoneal prosthesis under local anaesthesia when the patients clinical and physical conditions allow for it, always in day surgery, and using the PHS mesh when the hernia defect size fits with the connector diameter. This last possibility seems to be easier and more comfortable for the patient in the postoperative period.     

An unusual presentation of an incarcerated Spigelian hernia

Spigelian hernias are rare hernias, occurring through a defect in the Spigelian aponeurosis. Like other hernias, they may contain abdominal contents but are more likely to be incarcerated due to the small size of the fascial defect. Multiple intra-abdominal organs have reportedly been found in Spigelian hernias. A search of the literature showed only nine reported cases in which an appendix has been found within a Spigelian hernia. We present a patient with a history of lower abdominal pain since 10 weeks with a large intra-abdominal mass in the right iliac fossa. Due to abscess formation with spontaneous evacuation through the abdominal wall, drainage and incision were performed and the patient was treated with broad-spectrum antibiotics. An explorative laparoscopy after six weeks showed an incarcerated appendix in a Spigelian hernia.     

The split abdominal wall muscle flap--a simple, mesh-free approach to repair large diaphragmatic hernia

Purpose: The authors present a technique to repair large diaphragmatic hernias that is simple, can be done primarily, and offers a durable closure with living tissue.Methods: A review of congenital diaphragmatic hernias was performed for the period between January 1991 and August 2000. Repair types included primary repair, synthetic patch, or a split abdominal wall muscle flap. The split abdominal wall muscle flap is performed by downward rotation of the internal oblique and transversalis abdominal wall muscles. This repair requires that the initial subcostal incision be positioned at least 4 to 5 cm below the costal margin, low enough to insure an adequate length of muscle will be available to fill the defect.Results: Eight of 158 children with congenital diaphragmatic hernia underwent repair by abdominal wall muscle flap. Five of 8 had complete agenesis. Five survived the newborn period. Of the survivors, 4 of 5 required an additional surgical procedure, but none have had a recurrent hernia.Conclusions: The split abdominal wall muscle flap is an effective technique to close large diaphragmatic hernias. The repair was carried out successfully in 8 patients with massive defects. In the surviving patients, the repair has proven to be a durable restoration of the diaphragm.     

Incidence and outcome of surgical repair of spigelian hernia

BACKGROUND: A spigelian hernia develops through a defect present in a locus minoris resistentiae between abdominal muscles. It is generally considered rare but is probably underdiagnosed. This study was undertaken to characterize the history, presenting features and efficacy of surgical correction of spigelian hernia. METHODS: Medical and surgical charts of 25 patients treated for a spigelian hernia over 22 years were studied retrospectively. Patients were invited for an outpatient interview and physical examination. RESULTS: Dominant symptoms were an intermittent palpable mass (22 patients) and postural pain (16). A quarter of the patients reported a history of other hernias. Two individuals presented with a painful palpable mass and signs of bowel obstruction necessitating emergency small bowel resection. Hernia repair was performed by primary closure in 20 patients and by use of mesh graft in five. During a mean follow-up of 6.1 years, one early recurrence was observed. Two patients reported mild tenderness in the operated area but were not impaired in daily activities. CONCLUSION: Spigelian hernia is commonly encountered and requires surgical treatment because of the risk of strangulation. Operative treatment is simple and effective in the long term.     

Elastic fibers in the anterior abdominal wall

Purpose  

The aim of this study was to substantiate the hypothesis as to whether an altered amount of elastic fibers in the linea alba aponeurosis occurs or not in anterior abdominal wall hernias (epigastric, incisional and umbilical), comparing the findings with those of a control group of cadavers without hernias.     

Die bauchdeckenfunktion,die entstehung und die therapie von hernien (unter anderem: Die parakolostomiehernie)

The peritoneal cavity has a fascial skeleton with musculature that is nearly always active, i.e. it has resting tone activity. During pneumoperitoneum this resting activity increases very markedly. The pelvic floor and its integrated sphincters also have a similar type of spontaneous activity depending on Onuf's nucleus in the spinal cord together with the somatic and autonomic nerves. Hernias such as umbilical hernias develop with disruption of a scar. While in a child the common inguinal hernia develops in an open vaginal processus, in an adult it develops as the result of a congenital muscular defect in the abdominal wall. A femoral hernia develops in a gap through the pressure of the resting activity of the abdominal wall. A paracolostomy hernia develops after an incision in the fascial skeleton and after pull-through of a very adipose sigma-mesosigma. It can often be treated it by pulling a slim colon segment through the innervated rectus muscle incision and closing the gap in the fascial skeleton with a running suture. Incisional or umbilical hernias can be successfully treated by suturing with a continuous nonabsorbable thread. The best therapy for inguinal hernias is suturing of the hyperplastic fascia transversalis and the reconstruction of the muscle sphincter mechanism. Bassini operated on very large hernias with hyperplastic fascia, thereby achieving excellent results. Fascial hyperplasia has been shown to follow the use of tissue expanders.Prof. Dr. Dr. h.c. mult.
