A new technique in laparoscopic abdominal access (Evsen Method, Modified Veress Technique)

Area of Science:

• Minimally Invasive Surgery
• Surgical Techniques
• Gynecologic Laparoscopy

Background:

• Establishing pneumoperitoneum is critical in laparoscopic surgery, with many complications arising during initial abdominal entry.
• Existing methods for laparoscopic entry necessitate modification to decrease adverse events.
• The modified Veress technique (MVT), also known as the Evsen method, is introduced to address these concerns.

Purpose of the Study:

• To present and evaluate a modified Veress technique for establishing pneumoperitoneum in laparoscopic procedures.
• To compare the efficacy of the MVT against the classical Veress technique in terms of success rate, number of attempts, and time required.

Main Methods:

• A comparative study involving 40 patients undergoing laparoscopic procedures at Dicle University.
• The modified Veress technique (MVT) was applied to 26 patients, while the classical Veress method was used for 14 patients.
• Data on the number of attempts and time taken to establish pneumoperitoneum were recorded and analyzed.

Main Results:

• Pneumoperitoneum was established on the first attempt in 88.5% of MVT cases versus 50% in the classical Veress group.
• The MVT required a statistically significant lower number of insufflation attempts (p=0.022).
• Pneumoperitoneum establishment was significantly faster using the MVT (p < 0.00).

Conclusions:

• The modified Veress technique is superior to the classical Veress method for safe and efficient pneumoperitoneum.
• The MVT leads to fewer attempts and reduced procedure time, enhancing safety in laparoscopic surgery entry.
