Open veress assisted technique for laparoscopic entry

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.

Direct Trocar Insertion

Aim: To compare the outcomes in term of complication of Veress Needle Insertion (VNI) to Direct Trocar Insertion (DTI) for creation of pneumoperitoneum in laparoscopic cholecystectomy. Design: Randomized controlled trial Place and Duration of Study: The current analysis was conducted at Khawaja Muhammad Safdar Medical College Surgical Department, Allama Iqbal Memorial Hospital and Govt. Sardar Begum Teaching Hospital, Sialkot from September 27, 2017, to September 26, 2020. Methodology: A total of six hundred and eight (n=608) patients, having age 30 to 75 years planned for laparoscopic cholecystectomy were included in this study. Patients were randomly divided into two groups, Group A (Direct Trocar Insertion), Group B (Veress Needle Insertion). Both groups had age and sex matched males and female. All trocars and veress needle used were disposable, with a safety shield. The primary outcome of our study was to compare the complications to assess the safety levels, while total time taken by the procedure and mean time for laparoscopic entry were the secondary end points. The collected data was analyzed by using software SPSS version 22. Chi-square test was used to check the significance of variance. P-value less than 0.05 remained the statistically significant. Results: The complication rate in VNI group were significantly greater than the DTI group (p < 0.01), the duration of surgery between the two groups was not significantly different (p > 0.05), but we found statistically significant difference in mean laparoscope insertion time (DTI 3.4+ 1.4 versus VNI 4.8+ 0.7 minutes, p < 0.001). Conclusion: From the results of our study, it can be concluded that the direct trocar insertion is a safe alternative to veress needle insertion in laparoscopic cholecystectomy as it is associated with fewer complications.
