Abstract
Background: Laparoscopy is a minimally-invasive surgery performed in the abdomen or pelvis via small incisions with the help of a camera. It may be diagnostic or operative. It has two imaging techniques: two-dimensional, which is the standard, and three-dimensional, which has superiority in image quality and less time needed to perform the surgery.
Objective: The aim of this randomized controlled trial is to compare operative data and early postoperative outcomes of laparoscopic salpingectomy operations conducted using standard 2-D and 3-D laparoscopic vision systems.
Methods: Thirty-six patients were randomized in a 1:1 ratio to the 3 D laparoscopy group or the 2 D laparoscopy group using computer-generated random numbers. Clinical and demographic characteristics including age and body mass index (BMI) were recorded. All the procedures were performed by the senior author. All the procedures were performed under general anaesthesia. In 3 D laparoscopy group, salpingectomy will be performed by using Storz image 1 S 3D laparoscopy system (Karl Storz, Tuttlingen, Germany). Surgeons wear special 3 D polarization glasses. In 2 D laparoscopy group, salpingectomy was performed by using conventional 2 D laparoscopy system. In both groups, the mesosalpinx were coagulated as close as possible to the fallopian tube using bipolar electrocoagulation to avoid any compromise in the ovarian blood supply. At the end of the operation, the degree of difficulty experienced by the surgeon during excision of the hydrosalpinx, the estimated blood loss, the time required to excise the hydrosalpinx and the total operative time were recorded.
Results: On comparing the intraoperative findings of the 2D and 3D groups, we found lower operative time (p=0.0019), lower fallopian tube excision time (p<0.001) and higher comfort of the surgeon (p=<0.0001) in the 3D group compared to the 2D group, which were statistically significant. On the other hand, we found no statistically significant difference between the two groups intraoperative blood loss detected by delta hemoglobin (p=0.413).
Conclusions: 3D laparoscopy is very helpful and safer for the patients as it saves more time than 2D laparoscopy also that will be effective in decreasing the post operative complications beside its cosmetic effect
