Background: To compare cranial 15º angulation of Veres needle to classic Veress needle entry in closed laparoscopic entry in obese patients. Method: Patients with BMI index>30 were divided into two groups. Initial entry into the abdomen in Group 1 (n=29) was performed with the intraumbilical insertion of Veress needle in 90o angle relative to the horizontal plane. In Group 2 (n=31) the Veress needle was placed intraumbilically in a cranial direction, the tip of the needle towards the thoracic cavity, with an angle of 15o to the horizontal plane. Two groups were compared with respect of the operative outcomes. Results: In Group 2, the mean number of Veress needle entries attempt was significantly lower than Group 1 (p=0.01). Time to insertion of the Veress needle was found to be significantly shorter in Group 2 than in Group 1 (p<0.001). While entry failure occurred in 3 patients in Group 1 (10.3%), no failures were monitored in any patients in Group 2 (p= 0.01). Complication rate was significantly lower in Group 2 than in Group 1 (p= 0.03). Conclusion: Placement of Veress needle intraumbilically in a cranial direction at 15°angle to the horizontal plane increases entry success and reduces complications.

Background: Primary abdominal access still remains a challenge for laparoscopic surgery despite rapid advances. This study was conducted to prospectively analyse and compare risks and benefits of two different entry techniques namely, veress needle and direct trocar in laparoscopic gynaecological surgeries so as to obtain consensus on the optimal method to be followed to create pneumoperitoneum.Methods: This was a prospective randomized study conducted at Deen Dayal Upadhyay hospital, under Delhi government. During the period January 2014 to June 2016, 800 patients (20-65 years) operated laparoscopically by the same team of surgeons for various gynaecological conditions, were randomized in two groups: Veress needle group (VN) and Direct trocar group (DT). Each group comprised of 400 patients. Comparison of various parameters was done between the two groups.Results: Incidence of major complications in terms of visceral injuries was 0.75% (3/400) in DT group and nil in VN group. Open conversion rate (2/400 i. e. 0.5%) and number of attempts required to create pneumoperitoneum were also more in DT group. Failed access in previous surgery cases was 1.2% (1/38) in VN and 14.8% (4/27) in DT group. Incidence of port site bleeding (n=3) was also more in DT group. Although the incidence of minor complications such as extraperitoneal insufflations (n=5) and no. of failed access (n=6) were more in VN group, there was no incidence of any life-threatening complication.Conclusions: In our experience, there is clear evidence of advantage of using veress needle in preventing major complications. Veress needle is therefore safer, convenient and effective technique of creating pneumoperitoneum.
