Purpose To estimate the inter-observer reliability and agreement of offline analyses of three different ultrasound techniques for assessing tubal patency. Methods 100 tubes (n = 100) in 50 women were evaluated for tubal patency between November 2013 and July 2015 using ultrasound as index tests and laparoscopy as the reference standard. Three different ultrasound techniques were applied: two-dimensional grayscale ultrasound using air + saline as the contrast media (2D-HyCoSy); two- and three-dimensional grayscale ultrasound using foam as the contrast media (2 D/3D-HyFoSy); and the same technique but adding bi-directional power Doppler (2 D/3D-Doppler-HyFoSy)...

BACKGROUND: The aim of this study was to compare 2D and 3D-sonohysterosalpingography (2D - 3D- HyFoSy) with previous diagnostic laparoscopy in the diagnosis of tubal patency, and compare each procedure in terms of procedure's time, perceived pain and complication rate. METHODS: We prospectively recruited infertile women, previously submitted to laparoscopy and randomly allocated into 2D-HyFoSy (group I) and 3D-HyFoSy (group II). We analyzed the results in term of sensitivity, specificity, positive predictive value and negative predictive value in tubal patency evaluation of both procedures in comparison with laparoscopy...

PURPOSE: 3D imaging is an upcoming technology in laparoscopic surgery, and recent studies have shown that the modern 3D technique is superior in an experimental setting. However, the first randomized controlled clinical trial in this context dates back to 1998 and showed no significant difference between 2D and 3D visualization using the first 3D generation technique, which is now more than 15 years old. METHODS: Positive results measured in an experimental setting considering 3D imaging on surgical performance led us to initiate a randomized controlled pragmatic clinical trial to validate our findings in daily clinical routine...

BACKGROUND: Hysterectomy is one of the most common surgical procedures for women of reproductive age. Laparoscopy was introduced in the 1990es and is today one of the recommended routes of surgery. A recent observational study showed that operative time for hysterectomy was significantly lower for 3-dimensional compared to conventional laparoscopy. Complication rates were similar for the two groups. No other observational studies or randomized clinical trials have compared 3-dimensional to conventional laparoscopy in patients undergoing total hysterectomy for benign disease...

In the late 1980s the first laparoscopic cholecystectomies were performed prompting a sudden rise in technological innovations as the benefits and feasibility of minimal access surgery became recognised. Monocular laparoscopes provided only two-dimensional (2D) viewing with reduced depth perception and contributed to an extended learning curve. Attention turned to producing a usable three-dimensional (3D) endoscopic view for surgeons; utilising different technologies for image capture and image projection. These evolving visual systems have been assessed in various research environments with conflicting outcomes of success and usability, and no overall consensus to their benefit...

BACKGROUND: Usually laparoscopy is performed by means of a 2-dimensional (2D) image system and multiport approach. To overcome the lack of depth perception, new 3-dimensional (3D) systems are arising with the added advantage of providing stereoscopic vision. To further reduce surgery-related trauma, there are new minimally invasive surgical techniques being developed, such as LESS (laparoendoscopic single-site) surgery. The aim of this study was to compare 2D and 3D laparoscopic systems in LESS surgical procedures...

With the widespread introduction of minimally invasive surgery (MIS) in late 1987 by laparoscopic cholecystectomy, the practice and expectation of general surgery were changed forever. As the development of scientific technology, new techniques of MIS have sprung up all around the world. 3D laparoscopy surgery, natural orifice transluminal endoscopic surgery, da Vinci surgical system and other new technologies also need time to be verified, and this is the only way all new things should get though. They are very unique in their own right, and all have advantages and disadvantages...

INTRODUCTION: Conventional two-dimensional (2D) laparoscopy systems have the drawback of poor depth perception and spatial orientation. Three-dimensional (3D) laparoscopic systems have stereoscopic vision in which depth perception is achieved by different unique images received by each eye. We evaluated 3D laparoscopy in comparison with conventional 2D laparoscopy in urological procedures in a prospective randomized study. MATERIALS AND METHODS: Over a 19 month study period, 108 patients scheduled to undergo various urological procedures were randomized to either conventional 2D or 3D laparoscopy (2D n = 53; 3D n = 55)...

Rectal cancer with simultaneous liver metastasis is very common clinically. R0 surgical resection both for the original and metastatic tumor can achieve much better long-term oncological results. The operation types include traditional open procedures for both rectal cancer and liver metastatic resection; combination of laparoscopic resection of the rectal cancer and open procedure resection of the liver metastatic lesion; traditional laparoscopic-assisted rectal and liver metastatic tumor resection with small abdominal incision and total laparoscopic natural orifice specimen extraction surgery(NOSES) without abdominal incision...

Uterine artery pseudoaneurysms (UAP) are rare but potentially life-threatening lesions. They may occur after traumatic deliveries, cesarean sections, and other interventions. We present a case of a 39-year-old woman with a UAP. The patient was accurately diagnosed using ultrasound imaging, with subsequent diagnostic hysteroscopy and laparoscopic excision of the UAP. In the present case, a ligation of the artery branch was performed to provide accurate hemostasis during UAP dissection. The vascular lesion was partially enucleated and removed, followed by recreation of the previous uterine shape...
