Direct Trocar Insertion: an Efficient Access Technique for Laparoscopic Cholecystectomy

Aim: To evaluate the feasibility and safety of direct trocar insertion for gaining access to peritoneal cavity in laparoscopic cholecystectomy. Methods: An Observational study was conducted at Surgical unit II Ghulam Mohammad Mahar Medical College Hospital Sukkur from January 2016 to December 2020. Two thousand one hundred twenty (n=2120) patients were included in the study. All the patients who underwent laparoscopic cholecystectomy were included in the study. Informed and written consent was obtained from every patient to participate as study subject. Data was analyzed on SPSS version 16. Mean +/- standard deviation was calculated for age, first port access time and time to establish pneumoperitoneum. Results: Under general anesthesia with patient in supine posture, abdominal access gained by first making small incision of 10mm in skin and subcutaneous fat at sub umbilical region with No. 11 scalpel and then by direct trocar insertion followed by creation of pneumoperitoneum. Cholecystectomy performed. Study variables included first port access time, no. of attempts for DTI, extraperitoneal CO2 insufflation, port site bleeding, visceral injury, port site infection and port site hernia and were recorded on predesigned proforma. Variables like extraperitoneal CO2 insufflation, port site bleeding and visceral injury were expressed as percentage. Conclusion: We conclude that direct trocar insertion is the safe, quick and effective method for creation of pneumoperitoneum and should be employed routinely in all laparoscopic procedures.

A comparative study between direct safety trocar insertion versus veress needle technique for creating pneumoperitoneum in laparoscopic surgeries

Background: There are two methods of trocar insertion in laparoscopic surgeries one is direct insertion and second is Veress needle insertion. In this study we compared these two methods.Methods: In this study we divided 50 patients equally into two group group A for in group A patients, direct trocar insertion technique was used for creation of pneumoperitoneum whereas amongst patients of group B, pneumoperitoneum was created using Veress needle insertion technique.Results: The incidence of visceral injuries, vascular injuries and other post-operative complications were similar in both the groups. The present study observed no significant difference in failure rates between two methods.Conclusions: Both the techniques i.e.; Direct trocar insertion (DTI) and Veress needle technique are equally effective, safe and feasible for creation of pneumoperitoneum during laparoscopic procedure.

Comparison of Complications between Direct Trocar Insertion Versus Veress Needle for Creation of Pneumoperitoneum in Patients Undergoing laparoscopic Cholecystectomy: A Randomized Control Trial

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.

Comparison of the Number of Attempts in Creating Pneumoperitoneum for Laparoscopic Cholecystectomy Using Direct Trocar Versus Veress Needle Insertion

Aim: To compare the number of attempts at creating pneumoperitoneum for laparoscopic cholecystectomy using direct trocar versus veress needle insertion techniques. Design: Randomized controlled trial Place and Duration of Study: Department of Surgery, Allama Iqbal Memorial Hospital Sialkot and Govt. Sardar Begum Teaching Hospital, Sialkot from 27th September 2017 to 26th September 2020. Methodology: Six hundred and eight patients of both male and female patients, having uncomplicated cholelithiasis were selected. All participants were randomized into two equal groups, Group A (direct trocarInsertion) and the Group B (veress needle insertion). All trocars and veress needle used were disposable, with a safety shield. All procedures were carried out by the single experienced surgeons and his team. Data was noted, regarding age, sex, body mass index (BMI) and the number of attempts to create the successful pneumoperitoneum. Results: The number of attempts to create successful pneumoperitoneum in DTI group was significantly feweras compared to VNI group (p=0.026) but we found no statisticallysignificant difference between age, gender, and body mass index. Conclusion: The direct trocar insertion is a safe alternative to veress needle insertion in laparoscopic cholecystectomy because it requires fewernumber of attempts for successful creation of pneumoperitoneum as compared to the veress needle.

Native Umbilical Defect for Laparoscopic Entry

Background: The presence of defects in native umbilical in adults and its use as laparoscopic first entry site is poorly documented. It would likely be a safer method than the Veress needle and direct trocar insertion. This work aimed to report the prevalence and size of native umbilical defects, and their relationship with gender, age and body mass index. Methods: In 160 consecutive laparoscopic operations, a trans-umbilical incision was made and a defect at its base was looked for. When found, the defect was measured and used as the first port entry site. Relationships of presence of native defects and their sizes in relation to gender, age and BMI were analyzed. Results: The prevalence of a native defect in this series was 90%. Its presence had no relation with gender, age or BMI. Its size, however, positively correlated with age and BMI. No complications were related to the defect’s use for first laparoscopic entry site. Conclusion: A native umbilical defect is present in 90% of adults. Whenever present, it is recommended for use as the first port entry site by an open technique. This method is simple and safe and avoids unnecessarily inducing another defect.

Safety of Direct Trocar Entry in Laparoscopy in a Structured Fellowship Programme

Introduction:The best method of primary trocar insertion in laparoscopy remains controversial. There are advocates for both initial Veress needle insertion as well as direct trocar insertion.Aim of the study: This study was carried out to find out the complication rate of direct trocar insertion as a method of laparoscopic entry and find out the learning curve of trainees in a structured fellowship programme.Methodology: Retrospective analysis was done over period of 5 years with a sample size of 2053 subjects.Results: 2053 laparoscopic surgeries were examined. Overall complication rate was 0.38%; subjects with previous abdominal surgery were found to have higher complication rate as compared to ones with no history of prior surgery. [0.46% and 0.35% respectively]. All trainees gained reasonable degree of confidence within 6 months.Conclusion: Direct trocar insertion is a safe method of laparoscopic entry, which can be taught to trainees with no prior laparoscopic experience, without an increase in entry complications.International Journal of Human and Health Sciences Vol. 04 No. 01 January’20 Page : 51-54
