Abstract

Inguinal hernia repairs are one of the most common procedures performed in general surgical departments. Approximately 20 million hernia repairs are performed annually all over the world. According to the EHS guidelines, the recommended treatment methods of the inguinal hernia are tension–free techniques: the Lichtenstein open hernia repair and the laparoscopic transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) methods. The TEP hernia repair, first performed by Duluq in 1992, is one of the three current leading techniques in the inguinal hernia repair. The most important advantage of this technique is minimal invasive access without the need to open the peritoneum, which carries a lower risk of abdominal organs injury. Additionally, the TEP method facilitates shorter recovery time, less postoperative pain and an earlier discharge form hospital. The aim of the article is to present the TEP method by comparing it with the other inguinal hernia repair techniques, on the basis of the available literature.

Abstract

The aim of the study was to develop new laparoscopic technique for repeated recovery of sheep oocytes. Oocytes were aspirated with specifically designed catheter. It allowed to recover oocytes without ovary damage and to preserve very good quality of recovered oocytes. Fifteen ewes were oocytes donors. Oocytes were collected: one time (group I, n=15), two times (group II, n=15), three times (group III, n=10), four times (group IV, n=5). The endoscope was inserted into the abdominal cavity. Two trockars for putting the manipulators were inserted 15 cm cranial from the udder. Oocytes were collected by aspiration of the follicular fluid from the ovarian follicles. The observed clinical complications were: ovary bleeding and cicatrix at place of needle insertion, the fragmentary adhesion of infundibulum and ovary, adhesions of omentum and peri- toneum near the place where the grasping forceps were inserted and adhesion of ovary and uterus. Ovarian follicles (n=204) were aspirated, 130 (63.8%) oocytes were obtained. Out of 130 obtained oocytes, 112 were qualified for in vitro maturation. The remaining 18 oocytes (13.8%) were rejected due to cytoplasmic changes. The proposed technique allows for the collecting oocytes of good quality that can be used for IMV/IVF techniques and cloning.
