Wichterle hydron for breast augmentation - case reports and brief review.

During the period of 1960s and 1970s, a new alloplastic material - Wichterle gel - was introduced in the field of plastic surgery. In 1961, a Czech scientist, prof. Otto Wichterle, had developed, along with his research team, a hydrophilic gel made of polymers, which fulfilled the high standards for prosthetic materials due to its hydrophilic, chemical, thermal and shape stability that provided a better tolerance in the body compared with other hydrophobic gels.

The effect of three different surgical techniques for colon anastomosis on regional postoperative microperfusion: Laser Doppler Flowmetry study in pigs.

Background: The optimal surgical approach to reconnecting bowel ends safely after resection is of great importance.

Objectives: This project is focused on assessment of the perianastomotic microcirculation quality in the short postoperative period when using three different anastomosis techniques in experimental animal.

Methods: The experimental study involved 27 young female domestic pigs divided into three subgroups of 9 animals according to each surgical method of anastomosis construction in the sigmoid colon region: by manual suture, by stapler, or by gluing.
