Abstract:
Purpose :The purpose of this study is to compare the results obtained from three
laparoscopic techniques , Direct Trocar entry, Veress Needle, and Open Approach
(Hassons technique) and to see which is the best method of establishing
pneumoperitoneum.
Methods :We studied 288 patients admitted to our hospital for laparoscopic surgeries,
in a randomised prospective design, 96 patients were assigned each to Direct trocar
(DTI), Veress needle(VN) and Open Hassons Approach(OA).The variables analysed
were : Mean trocar insertion time, Gas leak, Subcutaneous emphysema and Intra
abdominal injuries.
Results :Mean trocar insertion time DTI, VN and OA are 77.6±22.4, 180.1±39.8 and
350±127.9 sec,p = <0.001 (Sig), gas leak in 0 (0%), 11(11%) and 39(40.6%) p
=<0.001 (Sig),subcutaneous emphysema in 0 (0%), 5(5.2%) and 12(12.5%) p=0.001
(Sig),and intra abdominal injuries 0 (0%), 2(2.1%) and 1(1.0%)
Conclusions :Our results show DTI to be a safe, efficient, rapid and easily-learned
alternative technique, reducing the number of procedure-related complications.
