Description

This educational video titled "Introduction of Veress Needle and Trocar Used in Minimal Access Surgery" offers a detailed overview of two of the most essential instruments used during the initial phase of laparoscopic procedures. In Minimal Access Surgery (MAS), safe entry into the peritoneal cavity is critical, and the Veress needle and trocar system play a central role in achieving that safely and effectively. Understanding the Veress Needle The Veress needle is a spring-loaded, blunt-tipped needle used to create pneumoperitoneum—the insufflation of carbon dioxide gas into the abdominal cavity to lift the abdominal wall and create a working space for laparoscopic instruments. The video demonstrates the correct technique for Veress needle insertion, typically at the umbilicus or supraumbilical region, including: Ensuring the needle is held at a 45 to 90-degree angle depending on patient BMI Confirming correct placement with saline drop test, aspiration test, and intra-abdominal pressure monitoring Troubleshooting incorrect placement and avoiding complications like preperitoneal insufflation or visceral injury Introduction to the Trocar Once pneumoperitoneum is achieved, the trocar is inserted to create the primary port for the laparoscope. The video showcases various types of trocars: Bladed vs. bladeless Optical (camera-guided) trocars Threaded trocars for stability The insertion process is shown step-by-step, emphasizing controlled entry, proper angulation, and techniques to reduce the risk of vascular or organ injury. The cannula of the trocar then serves as the access point for inserting the laparoscope or other instruments. Key Learning Points Highlighted in the Video Proper technique and anatomical landmarks for safe Veress needle insertion Tests to confirm correct placement before insufflation Differentiation and usage of various trocar types Avoidance of entry-related complications Role of open (Hasson) technique as an alternative in select patients Clinical Relevance Used in almost every laparoscopic procedure—including cholecystectomy, appendectomy, hernia repair, and TLH—the Veress needle and trocar represent the gateway to the minimally invasive approach. Mastery of their use is a fundamental skill for every laparoscopic surgeon and forms the basis of a safe and successful operation. Conclusion This video offers a practical, step-by-step guide to understanding and using the Veress needle and trocar—critical tools in the initiation of laparoscopic surgery. By following proper technique and safety protocols, surgeons can ensure effective abdominal access and reduce the risk of complications. Whether you're a trainee or an experienced surgeon, this resource enhances your foundational understanding of safe laparoscopic entry.
