J Allama Iqbal Med Coll Jan ;19(4):1017-9.

Background: The aim of this study is to compare the outcomes of veress needle entry versus direct trocar for laparoscopy in gynaecological surgery in relation to the complications encountered during each technique. Methods: The present study was conducted on a retrospective basis from September '2017 to September 2020, in the dept of Obstetrics and Gynecology, in Hameed Latif Hospital. All the cases who underwent laparoscopic procedure during this time were taken into account including diagnostic laparoscopy and operative both. In those patients traditional technique of veress needle entry was used for access were labeled as group -1 and in which direct trocar entry was dome were labeled as group-2. These two groups were compared in terms of the demographic profile, duration of procedure, previous h/o surgical interventions ,ease of performance and various complications encountered during the procedure. Results: The total number of patients who underwent laparoscopy during this period were 426, which were divided into two groups ,(veress needle entry group,group-1) 213 patients(50%), (direct trocar, group -2) 213 patients(50%).Duration of procedure was 4.5±1.2 min in group 1 which was significantly higher than group 2,2.2±0.8 min(p-value <0.001).Amount of gas required was greater in group 1, 4.9 ±1.3 lts as compared to group 2,2.4.0 ±0.3lts. Conclusions: Direct trocar entry is as reliable as traditional technique for pneumoperitoneum establishment with veress needle in relation to complications time duration and ease of performance.
