Purpose: To compare the results obtained from three routine laparoscopic entry techniques, including Direct Trocar (DT), Veress Needle (VN), and Open Approach (OA).
Materials and methods: Safety and efficacy of three main laparoscopic entry techniques were evaluated prospectively in 453 consecutive patients who had undergone laparoscopy either with DT, VN, or modified OA technique in recent six years.
Results: Of 453 patients, 105 (23.2%) were operated on with the DT, 168 (37.1%) with the VN, and 180 (39.7%) with the modified OA technique. Statistical differences were seen among the groups in terms of mean age (P = .003), male-to-female ratio (P < .001), indications for the operation (P < .001), and mean trocar insertion time (P < .001). Three major complications (1 colon perforation and 2 iliac artery injuries) occurred in DT and one (iliac artery injury) in VN group, and modified OA group had no major complication (P = .04). Four major complications required laparotomy. Minor complications were seen in 6 (5.8%), 9 (5.4%), and 17 (9.4%) patients (P = .274) and gas leakage in 4 (3.8%), 16 (9.5%), and 27 (15%) patients (P = .01) in DT, VN, and modified OA groups, respectively.
Conclusion: Although DT and VN are rapid and relatively safe, they can be associated with major complications. Therefore, modified OA seems to be safe, feasible, and most acceptable due to less major complications.
