Surgical Approaches in Minimally Invasive Cardiac Surgery
Published in Theo Kofidis, Minimally Invasive Cardiac Surgery, 2021
The main principles of the maze procedure can be applied minimally invasively. A small incision is made and a videoscope is inserted through an incision to view the heart (read more in Chapter 13) (Figure 6.44 and Figure 6.45).
Management problems

The most common commercially available robot is the da Vinci system, which comprises three units: a console, an instrument tower, and the operating robot. The surgeon sits at the console, controlling the robot and viewing a 3-dimensional image of the operative field streamed from a stereoscopic videoscope mounted on the robot via the instrument tower. The robot itself has four arms (earlier versions had three). One holds the video scope and the other three perform procedures with a variety of interchangeable instruments. The benefits over other forms of minimally invasive surgery (e.g. laparoscopy) are principally the 3-dimensional nature of the image which affords depth perception, the electronic filtering of hand tremor, and motion scaling in which a large movement by the surgeon is translated to a small movement by the robot, increasing precision. Though the surgeon is remote from the patient, scrubbed assistance is required.

The VLMs are an integral, multifunctional supraglottic airway device consisting of two parts [38]: (1) a second generation disposable SAD with anatomically curved shaped, separate gastric and ventilation channel allowing a functional separation, built-in bite block, silicone cuff, and a reinforced distal tip which allows a more compact seal and therefore a higher oropharyngeal sealing pressure; (2) a reusable flexible videoscope with built-in or stand-alone display. The videoscope is assembled in a closed tip completely sealing channel of the SAD specially designed to harbor it, preventing the reusable part from coming into contact with the patient to avoid contamination. The connection incorporates a click lock, which allows a solid hold of both parts and disconnection after finishing the procedure. This configuration allows easy assembly, usability, and the separation of the components from each other.
Comparison of surgical outcomes between 3-dimensional and 2-dimensional laparoscopy of ovarian cyst (LOOC): a randomised controlled trial
Published in Journal of Obstetrics and Gynaecology, 2022
Young Gi Han, Kyung Min Lim, Taejong Song
All surgical procedures were performed by one surgeon (T. Song), who had performed more than 2000 procedures of laparoscopic gynaecologic surgery, to control the variability of surgical skill. The laparoscopic port (or trocar) placement was determined according to a patient's condition and needs. With endotracheal intubation, general anaesthesia was achieved, participants were placed in the deep Trendelenburg position. After a pneumoperitoneum was created following insufflation with carbon dioxide to a pressure of 11 mmHg, a laparoscope was inserted through the umbilical port. For the laparoscopic camera system, a 10-mm ENDOEYE FLEX 3D Deflectable Videoscope LTF-190-10-3D (Olympus Corp., Germany) and a 10-mm 30° IDEAL EYES Laparoscope (Stryker, Kalamazoo, MI, USA) camera were used in the 3D groups and the 2D groups, respectively. The laparoscopic equipment used, the laparoscopic instruments and operative procedural steps were the same in both the 2D and 3D groups to ensure a standardised approach to every patient. Two display screens were adjusted by the circulating nurse to suit the surgeons’ height and comfort. The only difference between the two groups was the laparoscopic camera used.
Swallowing rehabilitation following spinal injury: A case series

At the research site, FEES were performed at the patient's bedside by a trained speech-language therapist using an Olympus ENF-V3 Ultra slim rhino-laryngo videoscope, Olympus OTV-SI compact video enabled digital processor and ADVAN 21” monitor (Olympus Corporation, Tokyo, Japan). A water-soluble lubricant was used to minimize patient discomfort. No topical anaesthetic was used. Fluids were mixed with blue or green dye (Hansells Food Coloring, Old Fashioned Foods Ltd. NZ) to improve visualization. The set protocol for FEES was: 30 s observation at rest, 3×5 mL Level 0 water, 1×50 mL water via straw or cup, 3×5 mL Level 2 mildly thickened water (Flavor Creations Australia), 1×50 mL Level 2 mildly thickened water via cup or straw followed by 3×5 mL Level 4 apple puree, a Level 6 banana and a Level 7 biscuit. The FEES protocol was truncated, as required, for safety.
