Up to the present, the optimal time to close an open abdomen remains controversial. This study was designed to evaluate whether early fascial abdominal closure had advantages over delayed approach for open abdomen populations. Medline, Embase, and Cochrane Library were searched until April 2013. Search terms included “open abdomen,” “abdominal compartment syndrome,” “laparostomy,” “celiotomy,” “abdominal closure,” “primary,” “delayed,” “permanent,” “fascial closure,” and “definitive closure.” Open abdomen was defined as “fail to close abdominal fascia after a laparotomy.” Mortality, complications, and length of stay were compared between early and delayed fascial closure. In total, 3125 patients were included for final analysis, and 1942 (62%) patients successfully achieved early fascial closure. Vacuum assisted fascial closure had no impact on pooled fascial closure rate. Compared with delayed abdominal closure, early fascial closure significantly reduced mortality (12.3% versus 24.8%, RR, 0.53,P<0.0001) and complication incidence (RR, 0.68,P<0.0001). The mean interval from open abdomen to definitive closure ranged from 2.2 to 14.6 days in early fascial closure groups, but from 32.5 to 300 days in delayed closure groups. This study confirmed clinical advantages of early fascial closure over delayed approach in treatment of patients with open abdomen.

The properties of meshes: Surgimesh®, Technomesh[Formula: see text] and SurgiproTM aged for up to four years were assessed using tensile tests. We discovered that the elasticity of Technomesh[Formula: see text] increased in both directions, Surgimesh[Formula: see text] became more elastic in the longitudinal direction while the elastic properties of SurgiproTM remained unchanged. The mesh samples did not significantly change their strength and deformability with age. Samples from umbilical and inguinal area of the abdominal wall were isolated from 14 donors. The investigation included 90 specimens divided into three age subgroups — A (up to 60 years), B (61–80 years) and C (over 80 years). The long-term mechanical compatibility of human fascia and meshes was compared. The elastic properties of the meshes are closer to the elastic properties of the fascia in the direction parallel to fibers if the donors’ age is up to 60 years.

A new monochromator called an extra-focus constant-included-angle varied-line-spacing (VLS) cylindrical-grating monochromator (extra-focus CIA-VCGM) is described. This monochromator is based on the Hettrick–Underwood scheme where the plane VLS grating is replaced by a cylindrical one in order to zero the defocus at three reference photon energies in the vacuum-ultraviolet range. It has a simple mechanical structure and a fixed focus spot with high performance over a wide energy range. Furthermore, its mechanical compatibility with a standard VLS plane-grating monochromator allows convenient extension into the soft-X-ray range.
