In recent years, there has been a growing need for skills quantification of endoscopic specialist. Various educational simulators have been created to help increase the endoscopy performance of medical students and trainees. Recent research seems to show that the use of simulators helps increase the skill level of endoscopists, while improving patient safety 1, 2 . However, previous simulators lack sufficient realism and are unable to replicate natural human reactions during endoscopy or quantify endoscopic skills...

Endoscopes extend the eyes of the physician into the patient's body. They are widely used in gastrointestinal (GI) diagnostics and minimally invasive surgery. Endoscopes can be classified into 3 types: rigid, flexible, and capsule endoscopes. Rigid and flexible endoscopes are traditionally held and manipulated by the physician to visualize the region of interest, while capsule endoscopes move passively along with the GI peristalsis. With the advancement of technology, robotic endoscopy has been increasingly developed and accepted...

BACKGROUND AND OBJECTIVE: While Minimally Invasive Surgery (MIS) offers considerable benefits to patients, it also imposes big challenges on a surgeon's performance due to well-known issues and restrictions associated with the field of view (FOV), hand-eye misalignment and disorientation, as well as the lack of stereoscopic depth perception in monocular endoscopy. Augmented Reality (AR) technology can help to overcome these limitations by augmenting the real scene with annotations, labels, tumour measurements or even a 3D reconstruction of anatomy structures at the target surgical locations...

BACKGROUND: There are 2 endoscopic surgical techniques that implement 3D vision to overcome visual misperception: 3D endoscopy and the da Vinci surgical system. 3D endoscopy has several advantages, such as the presence of tactile feedback and easy implementation, at lower costs. We aimed to assess whether 3D endoscopy could be an alternative to the robot during living donor nephrectomy (LDN). METHODS: Between April 2015 and April 2016 we prospectively collected data on 40 patients undergoing 3D endoscopic LDNs in 1 center, performed by a da Vinci certified surgeon...

Bioinspired robotic structures comprising soft actuation units have attracted increasing research interest. Taking advantage of its inherent compliance, soft robots can assure safe interaction with external environments, provided that precise and effective manipulation could be achieved. Endoscopy is a typical application. However, previous model-based control approaches often require simplified geometric assumptions on the soft manipulator, but which could be very inaccurate in the presence of unmodeled external interaction forces...

Since the development of capsule endoscopy technology, medical device companies and research groups have made significant progress to turn passive capsule endoscopes into robotic active capsule endoscopes. However, the use of robotic capsules in endoscopy still has some challenges. One such challenge is the precise localization of the actively controlled robot in real-time. In this paper, we propose a non-rigid map fusion based direct simultaneous localization and mapping method for endoscopic capsule robots...

Stone surgery is one of oldest surgical practices undertaken by man. Hippocrates refused to let his followers "cut for the stone" and it was only in February 1980, when the first human trial of shock wave therapy on a renal stone was performed with success that a new era in minimally invasive treatment (surgery) for stones was opened up and this condemnation was finally resolved in the Hippocratic Oath. Endoscopy, using natural orifices, supported by anaesthesia, incremented by technology and with access to all points along the urinary tract, began by competing with ESWL, but is now the treatment of choice in most cases...

Calyceal diverticula in children are rare and 20% eventually become symptomatic. Following the use of laparoscopic or endoscopic treatments, 85% of children report symptomatic relief. However, complete radiological resolution is seen only in three-fourths of the laparoscopic group and a quarter of those treated via endoscopy. Diathermy ablation of the lining and/or prolonged double J stenting has not altered this outcome. The robotic approach is superior to the other two techniques as the leak can be clearly identified and securely suture ligated...

Esophageal perforation is a rare but potentially fatal complication of robot-assisted thyroidectomy (RAT). Herein, we report the long-term outcome of an esophageal reconstruction with a jejunal free flap for esophageal rupture after RAT. A 33-year-old woman developed subcutaneous emphysema and hoarseness on postoperative day1 following RAT. Esophageal rupture was diagnosed by computed tomography and endoscopy, and immediate surgical exploration confirmed esophageal rupture, as well as recurrent laryngeal nerve injury...

BACKGROUND: The stereo laparoscope is an important tool for achieving depth perception in robot-assisted minimally invasive surgery (MIS). METHODS: A dynamic convergence accommodation algorithm is proposed to improve the viewing experience and achieve accurate depth perception. Based on the principle of the human vision system, a positional kinematic model of the binocular view system is established. The imaging plane pair is rectified to ensure that the two rectified virtual optical axes intersect at the fixation target to provide immersive depth perception...

Wireless capsule endoscopy (WCE) is performed with a miniature swallowable endoscope enabling the visualization of the whole gastrointestinal (GI) tract. One of the most challenging problems in WCE is the localization of the capsule endoscope (CE) within the GI lumen. Contemporary, radiation-free localization approaches are mainly based on the use of external sensors and transit time estimation techniques, with practically low localization accuracy. Latest advances for the solution of this problem include localization approaches based solely on visual information from the CE camera...
