Endoscopic submucosal dissection (ESD) is a well-established, minimally invasive treatment for superficial neoplasms of the gastrointestinal tract. The universal adoption of ESD has been limited by its slow learning curve, long procedure times, and high risk of complications. One technical challenge is the lack of a second hand that can provide traction, as in conventional surgery. Reliable tissue retraction that exposes the submucosal plane of dissection would allow for safer and more efficient dissection...

In thyroid surgery multiple different cervical minimally invasive (partly endoscopically assisted) and extracervical endoscopic (partly robot-assisted) approaches have been developed in the last 20 years. The aim of all these alternative approaches to the thyroid gland is optimization of the cosmetic result. The indications for the use of alternative and conventional approaches are principally the same. Important requirements for the use of alternative methods are nevertheless a broad experience in conventional thyroid operations of the thyroid and adequate patient selection under consideration of the size of the thyroid and the underlying pathology...

The idea to use natural orifices as an access route for operations in the body has inspired many clinicians and researchers worldwide. Some of these expected a continuation of the development from open surgery to laparoscopic surgery finally to a less invasive modality. Others hoped for economic benefits for endoscopists to take over previous surgical patients into gastroenterological departments. The first experimental studies demonstrated that the initial expectations could not be implemented in a short period of time...

Natural orifice transluminal endoscopic surgery (NOTES) is a surgical technique to perform "scarless" abdominal operations. Robotic technology has been exploited to improve NOTES and circumvent its limitations. Lack of a multitasking platform is a major limitation. Manual tool exchange can be time consuming and may lead to complications such as bleeding. Previous multifunctional manipulator designs use electric motors. These designs are bulky, slow, and expensive. This paper presents design, prototyping, and testing of a hydraulic robotic tool changing manipulator...

Natural Orifice Transluminal Endoscopic Surgery (NOTES) is an emerging field in minimally invasive surgery. NOTES can be performed via a variety of approaches, including through the stomach, esophagus, bladder, and rectum, but the majority of cases have been performed transvaginally. Potential advantages of natural orifice surgery in gynecology include the lack of abdominal incisions, less operative pain, shorter hospital stay, improved visibility, and the possibility to circumvent extensive lysis of adhesion to reach the pelvic cavity...

Endoscopic submucosal dissection is established as a curative endoscopic method for gastrointestinal epithelial neoplasms with a high possibility of complete en bloc resection; however, postoperative adverse events of bleeding and delayed perforation remain. To prevent or minimize them, several techniques for endoscopic mucosal closure have been introduced, such as using endoscopic clips, combined use of hemoclips and supplement devices, and specially designed endoscopic suturing devices. Furthermore, endoscopic full-thickness suturing technique for gastrointestinal wall defect has been developed based on the concept in natural orifice transluminal endoscopic surgery and endoscopic full-thickness resection...

Hysterectomy is one of the most commonly performed surgeries worldwide. Indication for hysterectomy is most often benign, which includes conditions such as prolapse, abnormal uterine bleeding, fibroids and pelvic pain. A broad range of surgical approaches exists for hysterectomy, ranging from open to minimally invasive techniques. Under this minimally invasive umbrella, the following techniques are included: vaginal hysterectomy, laparoscopic hysterectomy, and variations of those two techniques, such as laparoscopic-assisted vaginal hysterectomy, robotic-assisted hysterectomy, laparo-endoscopic single-site laparoscopic hysterectomy, mini-laparoscopic hysterectomy, and natural orifice transluminal endoscopic surgery hysterectomy...

Within the last 10 years there have been significant advances in minimal-access surgery. Although no emerging technology has demonstrated improved outcomes or fewer complications than standard laparoscopy, the introduction of the robotic surgical platform has significantly lowered abdominal hysterectomy rates. While operative time and cost were higher in robotic-assisted procedures when the technology was first introduced, newer studies demonstrate equivalent or improved robotic surgical efficiency with increased experience...

BACKGROUND: In natural orifice transluminal endoscopic surgery (NOTES) the peritoneal cavity is reached through natural orifices (mouth, rectus and transvaginal duct), by means of little cuttings in the walls of hollow organs. Due to narrow spaces, NOTES needs robotic systems to assure operation/movement precision and patient safety. Variable stiffness actuation (VSA) assures both requirements. METHODS: The authors developed a grasper for NOTES, provided with VSA, to use as an end-effector for snail robot devices...

The development and popularization of minimally invasive treatment is gradually evolving in the course of human fighting against disease. Minimally invasive surgery has been widely accepted and carried out because of the advantages of smaller trauma, less pain, little impact on the body and physiological metabolism of the body. The evidence-based medicine makes it important to conduct clinical trials to confirm the technical and oncological safety. With the development of minimally invasive technologies, including three-dimensional laparoscopic, natural orifice transluminal endoscopic surgery, robotic surgery system, minimally invasive surgery are providing more opportunities and challenges for gastrointestinal diseases...
