Abstract
Laparoscopic cholecystectomy (LC) is the “Gold standard” for elective treatment of symptomatic gallstone disease. Laparoscopic abdominal surgery requires creation of successful pneumoperitoneum with more than 50% of all complications occurring during the step of obtaining the access in to the abdomen.(52) Therefore, optimizing the entry technique is very crucial.
To date, there is still no evidence in literature as to which method, open or closed, is of choice for creating pneumoperitoneum. (40, 53-56)
In this randomized study, 162 patients with symptomatic gallstone disease were assessed for eligibility. A total of 62 patients were excluded, 50 for having PUH, and 12 patients for having upper abdominal scar from previous surgery. The collected100 patients constituted our study cohort which were randomly allocated to OT (optical trocar) and BT (blind trocar) groups with 50 patients per group.
We compared abdominal access to create pneumoperitoneum using either BT or OT with 50 patients per group undergoing laparoscopic cholecystectomy.
There was no statistically significant difference between both study groups as regards age, sex distribution, Body mass index, associated co-morbidities and the percentage of patients who had previous abdominal surgeries.
We found that the median number of attempts required for successful access of the abdominal cavity was significantly less in the BT-group compared to OT-group (1 VS 2, p0.001) which is in similarity compared to other studies.(37, 69)
In our study, the mean time required for successful abdominal access in the BT group was (1.59 ± 0.60 min) and was significantly shorter than the mean time required in the OT group (2.94 ± 1.18 min).
None of the patients included in our study experienced visceral or vascular complications related to the technique of entry similarly, none of the patient’s required conversion to open pertaining to the technique of entry.
