BACKGROUND: In this study, we evaluate a new bioadhesive for intra-abdominal onlay mesh fixation of a polypropylene-polyvinylchloride graft. METHODS: Three pieces of a commercially available polypropylene/polyvinylfluoride mesh, each 3 × 3 cm in size, and three pieces of the same mesh coated with a polysaccharide bioadhesive were fixated to the surface of the anterior abdominal wall of 30 New Zealand white rabbits. The fixation was performed either by using four transabdominal Prolene(®) 4/0 sutures, four spiral tacks (Protack 5 mm Tyco), or cyanoacrylate glue (Glubran(®) GEM, Viareggio, Italy). Each mesh position and the according kind of fixation were randomized before implantation. The animals were sacrificed 12 weeks postoperatively. After determining the extent of intra-abdominal adhesions, the meshes were excised en bloc with the anterior abdominal wall for tensile strength measurements and histological analysis. RESULTS: All meshes coated with the bioadhesive adhered to the intact peritoneum without extra fixation. Irrespective of the fixation technique coated meshes led to more and stronger adhesions. Mesh shrinkage by scarring was increased in coated meshes fixed with glue and low in uncoated meshes fixed with tacks. Testing the tensile strength, coated meshes fixed with transfascial sutures achieved the best results (16.14 ± 6.1 N), whereas coated meshes fixed with glue showed the lowest strength (10.39 ± 4.81 N). The foreign body reaction was considerably more distinctive using coated mesh. The mesh ingrowth was not influenced by this reaction. CONCLUSIONS: All meshes coated with the new bioadhesive were self-adhesive in that way; they stayed in position when attached to the peritoneum. Although this may facilitate intra-operative mesh fixation, the bioadhesive displayed several disadvantages, such as stronger adhesions and an increased shrinkage of the implant. The tensile strength was not influenced by the use of the bioadhesive. At present, we see no major advantage for polysaccharide bioadhesive applied in this study.

The transversus abdominis plane (TAP) block is an effective regional nerve block for the anterior abdominal wall. An anesthesiologist typically administers the TAP block preoperatively with ultrasound guidance. It is not yet commonly used during abdominoplasty, where postprocedural pain remains a major concern for patients and surgeons.

We report a 57 year- old man with lateral abdominal wall bulging. MRI showed thoracic disk herniation at the T11-T12 level. Needle electomyogram disclosed acute denervation in paraspinal and abdominal muscles innervated from T11 root. Eight months later the swelling was reduced significantly. Thoracic disc herniations are rare and three similar cases have been described previously.

Cytoreduction surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) improve survival and decrease recurrence of peritoneal metastasis in a select population of patients. Abdominal wall resection is often needed to achieve complete CRS and the extent of abdominal wall resection may necessitate abdominal wall reconstruction (AWR). We sought to investigate if postoperative morbidity and mortality was increased in patients who underwent AWR with CRS-HIPEC (AWR group) compared to CRS-HIPEC without AWR (non-AWR group) and to identify if patient, tumor, and operative risk factors were associated with poor outcomes following AWR. We postulate that AWR is a safe and viable treatment option in appropriately selected patients with peritoneal disease.

After reviewing this article, the participant should be able to: 1. List major risk factors for hernia formation and for failure of primary repair. 2. Outline an algorithmic approach to anterior abdominal wall reconstruction based on the degree of contamination, components involved in the deficit, and width of the hernia defect. 3. Describe appropriate indications for synthetic and biological mesh products. 4. List common flaps used in anterior abdominal wall reconstruction, including functional restoration strategies. 5. Describe the current state of the art of vascularized composite tissue allotransplantation strategies for abdominal wall reconstruction.

Most surgeons prefer to perform anterior abdominal wall lifting during abdominal entry to avoid damage to intestines or main vessels. Anterior abdominal wall lifting is assumed to prevent vital organ injuries by creating an adequate distance prior to entry into the peritoneal cavity. In this study, we compared the distance created for trocar entry into the peritoneal cavity with towel clamp lifting and towel clamp plus manual elevation of the anterior abdominal wall.

The umbilicus has a major role in the aesthetics of the anterior abdominal wall. Many publications deal with abdominal dermolipectomies but few focus on umbilicoplasty. However, these are essential in assessing the aesthetic result. Umbilicoplasty in “aile de mouette” used in our service is reliable and easily reproducible. In this article, we evaluate the satisfaction of patients with abdominal dermolipectomy with this technique of transposition.

Sarcoidosis is an inflammatory disorder that is characterized by the presence of noncaseating granulomas in tissues, involving many organs and tissues. Extra-pulmonary, especially muscular sarcoidosis is a rare condition. The most common location of the muscular sarcoidosis is known to be the proximal muscles of the extremities; however, there have been no cases of diffuse involvement of the chest and abdominal wall muscles. Here, we report a rare muscular sarcoidosis with infiltrative pattern in the chest and abdominal wall muscles and describe the MR imaging findings that were mistaken as lymphoma at initial diagnosis. Although our case did not show characteristic MR findings of muscular sarcoidosis, clinicians or radiologists who are aware of these imaging features can perform early systemic survey for sarcoidosis. Also muscle biopsy is very important to confirm the sarcoidosis and distinguish it from other tumors.

An abdominal wall pseudocyst refers to an encapsulated collection of fluid located superficially in the rectus abdominal muscles. This uncommon complication is diagnosed based on physical examination and computed tomography results. However, the etiology of its formation remains unclear. It can be effectively treated by surgery including complete excision of the cyst. Here, we report imaging findings of a giant pseudocyst in the anterior abdominal wall, following an open radical cystectomy.

The leiomyomas are a common gynecologic entity that may present unusual growth patterns or unusual locations. Its atypical presentations creates a diagnostic challenge. This is a case report of a parasitic leiomyoma located in the anterior abdominal wall in a 53 years old woman with pelvic compressive and urinary symptoms, with no history of any gynecological surgery. This case illustrates the diagnostic difficulties and describes the complementary images used in the preoperative evaluation.
