Background: Despite the good results reported after laparoscopic fundoplication, failure is still a major problem. Hiatal disruption is one of the common patterns of anatomical failure. The aim of this study was to compare the results of suture repair of diaphragmatic crura with routine polypropylene mesh reinforcement in addition to suture repair.
Methods: A total of 551 patients who underwent laparoscopic fundoplication for gastroesophageal reflux disease between March 1998 and July 2004 were included into the study. Crural closure had been performed with simple primary suture repair alone between March 1998 and July 2002 (n = 335, group I), and mesh reinforcement of the hiatal repair was performed routinely thereafter (n = 176, group II). These groups were evaluated prospectively.
Results: We observed a significantly lower rate of recurrence in group II than in group I. After a 2-year follow-up, the rate of anatomic morphologic recurrence was 6.0% in group I and 1.8% in group II. Considering the recurrence rate, there was significant statistical difference. The overall recurrence rate in our series was 4.6%. There was no correlation between the size of the hernia and recurrence. No significant difference was found between groups regarding the rate of postoperative dysphagia. We have not observed any complications related to the use of polypropylene mesh in group II.
Conclusion: The results of this study suggest that polypropylene mesh reinforcement increases the success rate for laparoscopic hiatal hernia repair without causing an additional complication burden. We propose routine use of mesh reinforcement in laparascopic antireflux surgery.

Purpose: Preoperative decision making prior to incisional hernia repair brings benefits but also presents challenges. Defect width (DW) is the key index in hernia staging but does not precisely indicate the requirement for component separation (CS). DW as a percentage of transverse abdominal diameter (TAD) determined by CT imaging was investigated for its capacity to indicate the necessity of CS for successful defect closure under physiological tension.

This paper introduces cross-wound CFRP shear reinforcement of hollow HPC beams. The CFRP reinforcement was manufactured in the form of a square tubular mesh from carbon rovings oriented at ±45° from the longitudinal axis. The shear reinforcement was made in two variants from carbon yarns with linear densities of 1600 and 3700 tex.

Industrial and construction wastes make up about half of all world wastes. In order to reduce their negative impact on the environment, it is possible to use part of them for concrete production. Using experimental-statistical modeling techniques, the combined effect of brick powder, recycling sand, and alkaline activator on fresh and hardened properties of self-compacting concrete for the production of textile-reinforced concrete was investigated.

A sequences of unconfined compressive strength tests and flexural tests were conducted in this study to evaluate the curing performance of a new type of polyurethane sand fast-curing polymer material. The mechanical properties of the material were investigated under different curing temperatures (-10 °C to 60 °C), particle sizes (10-15 mesh, 60-80 mesh, 100-120 mesh, and 325 mesh), and material proportions (20% to 60%). Additionally, SEM analysis was employed to further reveal the reinforcement mechanism.

Aiming at the problems of complex stress and large deformations in the surrounding rocks of the roadway driven under the goafs of small collieries and heading for adjacent advancing coal face, by numerical modeling and field practice, the failure characteristics of the overlying coal and rocks were investigated, and the stopping and resuming times of the roadway excavation were identified. A zoning-based reinforcement technique was put forward and applied in engineering practice. The results showed that (1) The roadway roof was divided into four zones: "Rolid coal zone", "Residual pillar zone", "Roof caved zone", and "Roof un-caved zone".
