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

Abstract

OBJECTIVES: The most important step in laparoscopic surgery is to safely establish the pneumoperitoneum, especially since approximately half of the complications occur during the initial entry into the abdomen. There is a distinct need to modify the available methods to reduce therate of adverse events in laparoscopic entry. In this study, a modified Veress technique (MVT) or Evsen method is introduced.The aim of this article was to present a modified Veress technique for establishing the pneumoperitoneum.
MATERIAL AND METHODS: The study was conducted at the Dicle University, Faculty of Medicine, Department of Obstetrics and Gynecology, from September 2016 to May 2017. A new laparoscopic entry technique was introduced and compared with the classical Veress technique. A total of 40 cases were included in the study. MVT and the classical Veress method were applied to 26 and 14 patients, respectively.
RESULTS: The pneumoperitoneum was established at the first attempt in 23 (88.5%) MVT patients and in 7 (50%) patients from the classical Veress method group. The number of insufflation attempts to establish a successful pneumoperitoneum was lower using MVT and the difference was statistically significant (p: 0.022). As far as time is concerned, a comparison between the groups revealed that the pneumoperitoneum was established in a statistically significantly shorter time using MVT (p < 0.00).
CONCLUSIONS: The modified Veress technique proved to be superior to the classical Veress method for establishing the pneumoperitoneum. Using the new method, the pneumoperitoneum was established after fewer attempts and in a shorter time.
