What data supports the idea that Blunt Fascial vs. Veress Needle Entry for Laparoscopic Surgery is an effective treatment?

The available research shows that both the Blunt Fascial (open) and Veress Needle (closed) techniques for laparoscopic surgery have their own benefits and risks. The study comparing these techniques found that the choice between them should be based on factors like the surgeon's experience and patient-specific details. The Veress Needle technique is associated with a low rate of injuries, but these can be serious if they occur. On the other hand, the open technique is suggested to reduce the risk of major injuries, especially in patients with abdominal scars. Another study introduced a new blunt-tipped tool that might be safer and faster than the Veress Needle, suggesting that alternatives to both traditional methods are being explored for better safety and efficiency.12345

What safety data exists for Blunt Fascial vs. Veress Needle Entry in laparoscopic surgery?

The Veress needle technique, commonly used for initiating pneumoperitoneum in laparoscopic surgery, has a low but notable risk of entry-related injuries, such as intestinal and major vascular injuries, occurring in 0.04-0.1% of cases. These injuries can result in mortality rates between 2.5 and 30% if undiagnosed. The open entry technique, although less popular, is considered safer with fewer complications. Studies comparing the two techniques suggest that the choice should be based on factors like patient characteristics and surgeon experience, as the Veress needle is associated with higher rates of complications, including vascular injuries and bowel perforations. Efforts to improve safety include developing devices like the abdominal wall entry suction device and improved Veress needle prototypes.24678

Is Blunt fascial abdominal entry, Veress needle abdominal entry a promising treatment?

The Veress needle technique is commonly used in laparoscopic surgery to create space in the abdomen for better visibility. It is a popular choice among surgeons due to its effectiveness in initiating the procedure. However, the choice between the Veress needle and other techniques often depends on the surgeon's experience and preference, as well as patient-specific factors.23489

What is the purpose of this trial?

This study aims to investigate the effect of two peritoneal entry techniques on intraoperative and post-operative outcomes among patients undergoing laparoscopic surgery with a minimally invasive gynecologic surgeon. Patients will be randomized to either blunt fascial or veress needle peritoneal entry. Insufflation times, failed entries, complications and post-operative pain scores will be collected.The investigators hypothesize that the blunt entry technique will be associated with shorter insufflation times and similar intraoperative and postoperative outcomes compared with the veress needle entry technique.Primary Objective: To evaluate the insufflation times and success upon peritoneal entry according to peritoneal entry technique.Secondary Objectives: To evaluate the surgical outcomes and patients pain scores according to peritoneal entry technique.

Findings from Research

In a study of 330 patients undergoing laparoscopic procedures, the routine use of an open technique for inserting the Veress needle significantly reduced the risk of severe complications, with no major vascular or visceral injuries reported.
Only 3.6% of patients experienced minor postoperative complications, demonstrating that the open technique is a safer alternative to the traditional blind method, especially in patients with abdominal scars.
Routine use of open technique in laparoscopic operations.Nuzzo, G., Giuliante, F., Tebala, GD., et al.[2022]
In a study of 365 patients undergoing laparoscopic abdominal surgery, the choice of entry technique (Veress needle vs. open technique) significantly influenced the occurrence of postoperative complications, particularly abdominal pain, which affected 40.5% of patients.
The findings suggest that the selection of the entry technique should be personalized based on individual patient factors and the surgeon's experience, highlighting the importance of tailored approaches in surgical practice.
Complications of Veress Needle Versus Open Technique in Abdominal Surgeries.Alhajress, GI., Al Babtain, I., Alsaghyir, A., et al.[2021]
In a study of 95 patients undergoing laparoscopic surgery, using concomitant CO2 insufflation during Veress needle entry resulted in a significantly higher success rate on the first attempt (89%) compared to subsequent insufflation (67%).
The time taken for adequate insufflation was similar between the two techniques, with no serious complications reported, indicating that both methods are safe but that concomitant insufflation may enhance initial entry success.
