The work presents results of the surgical treatment of postoperative hernias of the abdominal wall using explants of titanium nickelide in 48 patients. Data of biopsy of the anterior abdominal wall muscles in these patients are given. The anatomo-morphological and functional incompetence is shown. A method of preparing the patients with giant hernias to operation with the help of dynamic pneumocompression is described. The indications to using the explants in hernioplasty are determined by the methods of somatometry and intraoperative dynamometry. The data of three methods of combined hernioplasty are presented: with the use of a superelastic network from a nickelide-titanium alloy; explant with tractional properties, effect of the "shape memory"; method of extracorporeal extension of the abdominal wall at the postoperative period. The nearest and long-term results followed-up during 3 years are shown.

Atherogenesis is prone in medium and large-sized vessels, such as the aorta and coronary arteries, where hemodynamic stress is critical. Low and oscillatory wall shear stress contributes significantly to endothelial dysfunction and inflammation. Murray's law minimizes energy expenditure in vascular networks and applies to small arteries.

Objective: Laparoscopic nephron sparing surgery (NSS) can be performed by mainly 2 methods, offclamp or on-clamp. Continuous bleeding during the off-clamp method may impair the clear visualization of the border between the tumor and parenchyma, even though it is done safely in experienced hands. Therefore, some surgical modifications may be needed during mass excision and renorraphy.

The use of mesh repair is a frequently employed technique in the clinical management of abdominal wall defects. However, for intraperitoneal onlay mesh (IPOM), the traditional mesh requires additional fixation methods, and these severely limit its application in the repair of abdominal wall defects. We drew inspiration from the adhesion properties of mussels for the present study, functionalized carboxymethyl cellulose (CMC) with dopamine (DA), and added polyvinyl alcohol (PVA) to the composite to further improve the wet adhesive ability of hydrogels.

Background: Defect closure with mesh suture is a novel technique for hernia repair. Originally described as the construction of lightweight macroporous polypropylene mesh strips as a suture material, it is now available as an FDA-approved product. Mesh suture better distributes tensile forces and reduces fascial tearing compared to traditional suture but requires less implanted material and tissue dissection compared to planar mesh.

A 59-year-old man visited our hospital for examination of left-sided abdominal bulging. About a week earlier, he had developed an abdominal skin rash and was diagnosed with herpes zoster. Computed tomography excluded intra-abdominal organic disease and true hernia.
