Study Objective:
Fifty percent of laparoscopic bowel and vascular injuries occur at the time of entry. These serious complications can lead to significant morbidity and even mortality. This video demonstrates 3 techniques that have been developed to minimize the risk of these injuries during entry.
Design:
Step-by-step description of 3 techniques that can be used as a highly reliable and safe method of obtaining intraperitoneal entry during laparoscopy.
Measurements And Main Results:
Caudal displacement of the umbilicus before insertion of the veress needle allows for a median displacement of 6 cm between the site of entry and the common iliac vessels. An entry pressure of less than 9 mm Hg is suggestive of successful intraperitoneal entry. The left upper quadrant should be used in specific cases instead of the umbilicus as the point of entry for the veress needle. The use of a visualized trocarless cannula instead of a conventional primary trocar for entry after insufflation allows for real-time recognition of injury and converts linear penetrating force to radial torque.
Conclusion:
These 3 techniques can help decrease the risk and improve intraoperative recognition of serious bowel and vascular injuries during laparoscopy.

What is Glycolysis?
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP). The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from the Latin glyco (sugar) and lysis (breakdown). Glycolysis serves two main intracellular functions: generating ATP and generating...
