OTHER: Veress needle technique
|
The angle of the Veress needle insertion is 45 for non-obese women. After insertion of the needle, tests to determinate its correct positioning are: the double click test, the aspiration test, the handing drop test, serial intrabdominal gas pressure measurements. The volume of CO2 inserted with the Veress needle depends on the intra-abdominal pressure. Adequate pneumoperitoneum should is determined by a pressure of 20 to 30 mm Hg and not by predetermined CO2 volume. Direct insertion of the trocar is performed without prior pneumoperitoneum. Infra-umbilical skin incision is wide enough to accomodate the diameter of a sharp trocar/cannual system. The abdominal wall is elevated by pulling on, by hands, two towel clips placed 3 cm on either side of the umbilicus, and the trocar is inserted at a 90°angle. On removal of the sharp trocar, the laparoscope is inserted to confirm the presence of omentum or bowel in the visual field.
A small incision, 1 cm long, is made through the skin of the lower edge of the umbilical fossa.
The skin and the subcutaneous adipose tissues are retracted with the Zimmerman dissectors.
The anterior rectus fascia is incised with the scalpel.
The dissection with the Zimmerman valves allows the exposure of the peritoneum.
After the peritoneum is incised, the trocar is inserted under direct vision.
The laparoscope is introduced and insufflation is started.
At the end of the procedure the fascial defect is closed.
