This paper discusses how the 'Uncatchable Smile' illusion in Leonardo da Vinci's La Bella Principessa portrait was discovered. Kemp and Cotte(1) described the expression of the Princess as ambiguous and "subtle to an inexpressible degree". A combination of three methods was used (inter-observation, structured interviews, and psychophysical experiments) to identify what may underlie this 'ambiguity'. The inter-observation and the structured interview methods were firstly applied to generate experimental hypotheses that were successively tested by a series of psychophysical experiments...

BACKGROUND: Open posterior spinal procedures involve extensive soft tissue disruption, increased hospital length of stay, and disfiguring scars. Our aim was to demonstrate the feasibility of using robotic-assistance for minimally invasive exposure of the posterolateral spine with and without carbon dioxide (CO2 ) insufflation. METHODS: Sheep specimens underwent minimally invasive subperiosteal dissection of the spine during three trials. The da Vinci S Surgical system was used for access with and without working space support via CO2 insufflation...

The concept of complete mesocolic excision and central vascular ligation for colonic cancer has been recently introduced. The paper describes a technique of right-sided complete mesocolic excision and intracorporeal anastomosis by using a single-port robotic approach with an additional conventional robotic port. We performed a single-port plus an additional port robotic surgery using the Da Vinci Single-Site platform via the Pfannenstiel incision and the wristed robotic instruments via an additional robotic port in the left lower quadrant...

The standard treatment for patients with obstructive sleep apnea syndrome is positive airway pressure (PAP) therapy. However when PAP therapy fails, surgery maybe an option to alleviate the obstruction. The base of tongue plays an important role in this obstruction, and addressing the tongue base surgically can be a challenge for the head and neck surgeon. Transoral robotic surgery (TORS) using the da Vinci Surgical System provides a safe and effective way to approach and manage the base of tongue and supraglottis...

The objective of this study was to evaluate whether robotic tubal reanastomosis after segmental resection of tubal pregnancy is a feasible means of preserving tubal integrity and natural fertility in those with compromised contralateral tubal condition.The study was performed at a university medical center in a retrospective manner where da Vinci robotic system-guided segmental resection of tubal ectopic mass followed by reanastomosis was performed to salvage tubal patency and fertility in those with a single viable fallopian tube...

The use of the da Vinci robot for inguinal and ventral hernia repair has exponentially increased over the last five years. This increase is occurring in spite of historical cost analyses showing robotic surgery to be cost prohibitive for other general surgery procedures. Specific data regarding outcomes and cost analysis for hernia is lacking. The increase in robotic hernia repairs is likely related to intangible factors such as enhanced visualization, articulating instruments, and hospital resources. Further study of robotic hernia repair is needed prospectively as its use increases to delineate the true benefits...

OBJECTIVES: The current report describes the feasibility of robotic retroperitoneal lymph node dissection (RRPLND), including some technical tricks for port placement for both right- and left-sided surgery. METHODS: Patients with advanced stage retroperitoneal disease underwent RRPLND using the 4-arm da Vinci Si Surgical System (Intuitive Surgical, Inc.). In both cases, the field of dissection was an ipsilateral template for lymph node dissection. RESULTS: RRPLND in such configuration was safe and effective in both cases...

There is a small subset of patients who have undergone endoscopic thoracic sympathectomy for hyperhidrosis or facial blushing who are dissatisfied and would wish reversal. Compensatory sweating is the most common side effect that causes a person to regret surgery. Treatment options are limited and usually not effective in patients with severe side effects from sympathectomy. Nerve graft interposition has been proven to be effective in experimental models and small clinical series. Da Vinci robotic nerve graft reconstruction with interposition graft and direct suturing of nerve and high magnification dissection most closely mirrors standard nerve reconstruction principles when done as a minimally invasive procedure...

Superior hypogastric plexus (SHG) contains mainly sympathetic and most probably also postganglionic parasympathetic fibers. Thus, surgical damage of SHG may cause autonomic pelvic organ dysfunction (Kraima et al., 2015). As already shown for rectal cancer, preservation of the autonomic nerves is facilitated by robotic surgery and may avoid sexual dysfunctions and voiding disorders (Kim et al., 2015). In this educational video, we demonstrate left lower paraaortic lymph node dissection preserving the SHG using ICG fluorescence to label the lymphatic compartment...

PURPOSE: In this study, we examine three-dimensional (3D) proctoring tools (i.e., semitransparent ghost tools overlaid on the surgeon's field of view) on realistic surgical tasks. Additionally, we develop novel, quantitative measures of whether proctors exploit the additional capabilities offered by ghost tools. METHODS: Seven proctor-trainee pairs completed realistic surgical tasks such as tissue dissection and suturing in a live porcine model using 3D ghost tools on the da Vinci Xi Surgical System...

BACKGROUND AND OBJECTIVES: The general surgeon's robotic learning curve may improve if the experience is classified into categories based on the complexity of the procedures in a small community hospital. The intraoperative time should decrease and the incidence of complications should be comparable to conventional laparoscopy. The learning curve of a single robotic general surgeon in a small community hospital using the da Vinci S platform was analyzed. METHODS: Measured parameters were operative time, console time, conversion rates, complications, surgical site infections (SSIs), surgical site occurrences (SSOs), length of stay, and patient demographics...

Objective: To summarize clinical experience on application of transoral robotic surgery (TORS) in pharyngeal tumour resection. Methods: Six patients underwent TORS with da Vinci(®) surgical system in our department from November 2013 to July 2015 and their clinical data were analyzed retrospectively. Results: TORS was accomplished successfully in all 6 patients. The surgical field-exposed time ranged from 30 to 40 minutes with an average of 35 minutes. The operative time ranged from 30 to 130 minutes with an average of 72 minutes...

BACKGROUND: While an increasing number of open procedures are now routinely performed laparoscopically or robotically, minimally invasive pancreaticoduodenectomy (MIPD) remains one of the most challenging operations in abdomen. The aim of this study is to evaluate the current status and development of MIPD. METHODS: Embase, Medline, and PubMed databases were searched to identify studies up to and including Feb 2016 using the keywords "laparoscopic", or "laparoscopy", or "hand-assisted", or "minimally invasive", or "robotic", or "da vinci" combined with "pancreaticoduodenectomy", or "duodenopancreatectomy", "Whipple", or "pancreatic resection"...

The da Vinci system (da Vinci Surgical System; Intuitive Surgical Inc.) has rapidly developed in several years from the S system to the Si system and now the Xi System. To investigate the surgical feasibility and to provide workflow guidance for the newly released system, we used the new da Vinci Xi system for transoral robotic surgery (TORS) on a cadaveric specimen. Bilateral supraglottic partial laryngectomy, hypopharyngectomy, lateral oropharyngectomy, and base of the tongue resection were serially performed in search of the optimal procedures with the new system...

BACKGROUND: Increasing usage of robotic surgery presents surgeons with the question of how to acquire the special skills required. This study aimed to analyze the effect of different exercises on their performance outcomes. METHODS: This prospective study was conducted on the da Vinci Skills Simulator from December 2014 till August 2015. Sixty robotic novices were included and randomized to three groups of 20 participants each. Each group performed three different exercises with comparable difficulty levels...
