Robotic endoscopy

Long Chen, Wen Tang, Nigel W John, Tao Ruan Wan, Jian Jun Zhang
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...

Background and study aims : Capsule endoscopy (CE) is invaluable for minimally invasive endoscopy of the gastrointestinal tract; however, several technological limitations remain including lack of reliable lesion localization. We present an approach to 3D reconstruction and localization using visual information from 2D CE images. Patients and methods : Colored thumbtacks were secured in rows to the internal wall of a LifeLike bowel model. A PillCam SB3 was calibrated and navigated linearly through the lumen by a high-precision robotic arm...

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...

A reliable, real time localization functionality is crutial for actively controlled capsule endoscopy robots, which are an emerging, minimally invasive diagnostic and therapeutic technology for the gastrointestinal (GI) tract. In this study, we extend the success of deep learning approaches from various research fields to the problem of sensor fusion for endoscopic capsule robots. We propose a multi-sensor fusion based localization approach which combines endoscopic camera information and magnetic sensor based localization information...

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...

Recent biotechnological advances, including three-dimensional microscopy and endoscopy, virtual reality, surgical simulation, surgical robotics, and advanced neuroimaging, have continued to mold the surgeon-computer relationship. For developing neurosurgeons, such tools can reduce the learning curve, improve conceptual understanding of complex anatomy, and enhance visuospatial skills. We explore the current and future roles and application of virtual reality and simulation in neurosurgical training.

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...

BACKGROUND: Ectopic parathyroid glands may complicate the surgical approach to primary hyperparathyroidism. We describe a rare ectopic parathyroid location, the pyriform sinus. METHODS: Three patients, 2 after prior unsuccessful parathyroid exploration, were found to have ectopic parathyroid adenomas in the pyriform sinus. Two cases were identified by 4D-CT of the neck. The other was localized by a technetium 99m sestamibi single photon emission CT (SPECT). In each case, office endoscopy confirmed the lesions...

Minimally invasive surgical interventions in the gastrointestinal tract, such as Endoscopic Submucosal Dissection (ESD), are very difficult for surgeons when performed with standard flexible endoscopes. Robotic flexible systems have been identified as a solution to improve manipulation. However, only a few such systems have been brought to preclinical trials as of now. As a result, novel robotic tools are required.

BACKGROUND: Postgraduate training has been haphazard to date. Surgeons have relied on attendance to annual meetings and multiple choice study guides to demonstrate maintenance of certification and continuing medical education. METHODS: SAGES held a retreat to develop the concept and scope of the Masters Program. Surveys were sent to SAGES members to guide curriculum development and selection of anchoring operations. RESULTS: SAGES has developed an educational curriculum across eight domains (Acute Care, Biliary, Bariatric, Colorectal, Hernia, Foregut, Flex Endoscopy, and Robotic Surrey) incorporating SAGES educational materials and guidelines, social media, coaching and mentoring...

AIM: Gastrointestinal stromal tumors (GIST) are quite rare tumors, but yet they are the most common mesenchymal lesions of gastrointestinal tract. Their outmost frequent origin site is stomach and presently surgical resection is the mainstay in the treatment of gastric non metastatic GIST. Their peculiar characteristic of growth and poor metastatic tendency make this tumors particularly prone to be managed by minimally invasive technique. Presenting our experience we want show the feasibility and safeness of laparoscopic approach for gastric GIST and its benefits versus traditional open surgery and pointing out short term and long terms outcomes...
