The objective of this study was to evaluate physical, mechanical, and biological properties of the polydioxanone (PDO) monofilament meshes and polyglycolide (PGA) polyfilament meshes in comparison with Permacol® implants. In rat experimental model, a 1.5 × 2.0 cm defect in abdominal wall was reconstructed by using the Permacol surgical implant or knitted meshes produced from either PDO monofilament, or PGA multifilament. The implant sites were assessed for the tensile strength and the extents of material resorption, host inflammatory response and host tissue replacement on days 3, 10, 30, or 60 after the surgery...

RATIONALE: Pentalogy of Cantrell, a very rare congenital condition, has an estimated incidence of 5.5 per 1 million live births. It includes five defects: a midline supraumbilical wall defect, a diaphragmatic defect, a cleft distal sternum, a defect in the diaphragmatic pericardium, and an intracardiac defect. Very few cases of this condition have been reported in the literature, most of them diagnosed in the second or third trimester of pregnancy. PATIENT CONCERNS: We present a case of pentalogy of Cantrell associated with cranioschisis and unilateral anophthalmia diagnosed at 14 weeks of amenorrhea...

Cantrell syndrome (CS) or pentalogy of Cantrell is defined as a rare condition involving a midline anterior abdominal wall defect, a distal sternal cleft, a defect of the anterior diaphragm, and a defect of the apical pericardium with pericardio-peritoneal communication, as well as intracardiac anomalies. We report the case of a male newborn with type 2 CS diagnosed during intrauterine life based on ultrasonographic evaluation. Clinical examination at birth revealed an abdominal wall defect with extrathoracic displacement of the heart and a diastasis of the sagittal suture...

Inguinal hernia is a defect disease in the abdominal wall. Surgeons have tried various ways to repair the defect for more than 100 years. The traditional herniorrhaphy destroys the normal anatomical structure, and the recurrence rate is quite high. After that, surgeons began to repair the defects with prostheses, from the initial use of rough metal materials such as silver, tantalum, stainless steel, to nylon, fiberglass, silicone rubber and other non-metallic materials, and also from artificial synthetic polymer non-absorbable materials such as polypropylene, polyester, ePTFE, to synthetic absorbable materials such as polyglycolic acid and the acellular extracellular matrix derived from biological meshes...

Abdominal incisional hernia is the result of the loss of the integrity and tension balance of the abdominal wall. According to clinical manifestation and physical examination, most incisional hernia can be clearly diagnosed. For small and concealed incisional hernia, the diagnosis can be confirmed by imaging examination. According to size of defect, it can be divided into small, middle, large, and giant incisional hernia. According to location of lesion, it can be divided into incisional hernia in the central or peripheral region of the anterior abdominal wall, in the lateral abdominal wall, and in the back...

Diastasis recti is a relatively common condition in which there is a midline abdominal bulge that can affect a variety of individuals. The etiology and diagnosis is well understood and optimal management depends on the degree of severity. Patients at high risk for diastasis recti include multiparous women, obese patients, and those with multiple previous operations. Diagnosis includes clinical examination and assessment of symptoms. Physical characteristics include a midline abdominal bulge without a fascial defect...

REVIEW
Sahil K Kapur, Charles E Butler
Lateral abdominal wall defects, while rare, present a more challenging problem than commonly encountered ventral defects due to the complexity of the anatomy, physiologic forces, and impact of muscle denervation. The lateral abdominal wall encompasses a large surface area ranging from the costal margin superiorly to the iliac crest inferiorly and from the linea semilunaris anteriorly to the paraspinous musculature posteriorly. The ratio of muscle to fascia/aponeurosis is much higher, which makes repair through muscle tissue versus fascia less secure...

Due to the abundant and lax tissue of the abdominal wall, most ventral trunk defects are amenable to local soft tissue closure. However, when abdominal defects are accompanied by a lack of soft tissue, the surgeon faces a more complex subset of reconstructions. Three important principles guide the reconstruction of these wounds: timing of closure, careful assessment of the true extent of the wound, and the components of the defect. This article focuses on these three guiding principles and suggests the authors' preferred technique for these difficult defects...

BACKGROUND: Parastomal herniation is a common problem following formation of a stoma after both elective and emergency abdominal surgery. Symptomatic hernias give rise to a significant amount of patient morbidity, and in some cases mortality, and therefore may necessitate surgical treatment to repair the hernial defect and/or re-site the stoma. In an effort to reduce this complication, recent research has focused on the application of a synthetic or biological mesh, inserted during stoma formation to help strengthen the abdominal wall...

INTRODUCTION: We evaluated the usefulness of xeno-Biosheets, an in-body tissue architecture-induced bovine collagenous sheet, as repair materials for abdominal wall defects in a beagle model. MATERIALS AND METHODS: Biosheets were prepared by embedding cylindrical molds into subcutaneous pouches of three Holstein cows for 2-3 months and stored in 70% ethanol. The Biosheets were 0.5 mm thick, cut into 2 cm × 2 cm, and implanted to replace defects of the same size in the abdominal wall of nine beagles...

OBJECTIVES: Inguinal hernias of the abdominal wall are common accounting for 75% of all hernia defects. They can be treated with laparoscopic surgery using a transabdominal preperitoneal (TAPP) approach. However, in surgery there is some contention on how to conclude the hernia repair, as there are alternatives of using fibrin sealant (FS) or tack screws for fixation of a mesh implant over the defect in the abdominal wall. In this study, we evaluate the economic consequences of using FS vs...

Although ultrasound is still the gold standard for the assessment of fetal malformations, magnetic resonance imaging (MRI) has gained great prominence in recent years. In situations in which ultrasound has low sensitivity, such as maternal obesity, abdominal scarring, and oligohydramnios, MRI has proven to be a safe and accurate method. Regarding fetal abdominal wall defects, MRI appears to be widely used in the prognostic assessment of gastroschisis with intestinal atresia or of complications of omphalocele, allowing better perinatal management and parental counseling...

Classical bladder exstrophy (CBE), affecting 1 birth out of 30,000, is characterized by an evaginated bladder plate through a defect in the lower abdominal wall, multiple abdominal wall anomalies including a pubic bone arch dehiscence. Numerous approaches from childhood to adulthood are thus required, depending on the severity of the deformity, including the associated genital anomalies. We report the case of a 19-year-old woman with CBE with a history of three-failed primary closure. We performed a secondary neck closure with a concomitant suspension of the bladder neck and reconstruction of the lower abdominal wall using a bilateral gracilis muscle flap transposition...

INTRODUCTION: A Spigelian hernia is a rare type of abdominal wall hernia occurring in an area of congenital or acquired defect. These hernias occur in an area called the Spigelian zone and are interparietal making for a difficult diagnosis on clinical exam. PRESENTATION OF CASE: A 74-year-old female presenting with bilateral inguinal herniae and a left sided Spigelian hernia. The repair was done laparoscopically with an intra-corporeal suture closing the Spigelian hernia neck...

INTRODUCTION: In extensive radionecrosis following radiotherapy for breast cancer (BC) treatment, the defect after excision can be reconstructed with a transverse rectus abdominis myocutaneous (TRAM) flap. In this study, we report outcome of free TRAM flap using contralateral internal mammary artery (IMA) as a recipient in comparison with pedicled TRAM. METHODS: We reviewed cases of chest wall radionecrosis following BC treatment during the past 8 years. Radionecrosis involving full-thickness soft tissue with defect sizes greater than 10 × 10 cm were included...
