Introduction In obese patients with hiatal hernia (HH), laparoscopic sleeve gastrectomy (LSG) with cruroplasty is an option but use of prosthetic mesh crura reinforcement is debated. The aim was to compare the results of hiatal closure with or without mesh buttressing during LSG. Methods Gastroesophageal reflux disease (GERD) was assessed by the Health-Related Quality of Life (GERD-HRQL) ques...

3-D geo-information is essential for many urban related applications. Point cloud and mesh are two common representations of the surface. Compared to point data, possesses indispensable advantages, such as high-resolution image texture sharp geometry representation. Semantic segmentation, an important way obtain geo-information, however, mainly performed on data. Due complex representation lack...

BACKGROUND Wound dehiscence and incisional hernia are potentially serious complications following abdominal surgery, especially if performed through a midline incision. Although prophylactic reinforcement with on-lay mesh has been shown to reduce this risk, a permanent mesh carries the risk of seroma formation, infection, and persistent pain. The aim of this study was to assess the safety of a ...

Despite extensive experience and significant reduction of complications in recent years, laparoscopic treatment of complex abdominal hernias is a challenge even for the experienced endoscopic surgeon. Patients with severe incisional hernias or symptomatic rectus diastasis benefit from the closure of the linea alba as a morphological and physiological reconstruction of the abdominal wall followe...

It is clear that the recurrence rates after nonprosthetic methods for the repair of inguinal hernias, like McVay, Bassini or Shouldice techniques, are high (6-10%). Since 20 years, we are convinced, in the GREPA-EHS group, about the advantages of the use of a prosthetic mesh in majority of patients for repairs of primary or recurrent inguinal hernias and incisional hernias. We describe our typi...

The convergence-confinement method, based on the analysis of the stress and strain state that develops in the rock around a circular tunnel, has been presented in this study with the two analytical solutions that have been most frequently used in recent years. Problem statement: Thanks to the increased power of electronic processors and the spread of numerical methods, the role of the convergen...

Abstract Inspection of ageing, reinforced concrete structures is a world-wide challenge. Existing evaluation techniques in civil and structural engineering have limited penetration depth do not allow to precisely ascertain the configuration reinforcement within large objects. The big challenge for critical infrastructure (bridges, dams, dry docks, nuclear bioshields etc.) understanding internal...

Abstract Vibro-compaction is a recent technique for treating soils in the mass, thus improving its mediocre geo mechanical properties. In addition, this treatment makes it possible to minimize risk of liquefaction, closely linked grain size soil be treated. The underlying construction project port Nador Morocco requires improve characteristics and particular given that collision zone, near bord...
