In times when technological advancements rapidly follow one another, two points have to be always remembered: the starting point of modern history rectal cancer surgery can well placed in time and we are witnessing incoming a new era surgery, where machines increasingly providing stronger support for human hand. twenty-first century, limits treatment continue pushed, with still representing pri...

INTRODUCTION A novel robotic platform for Natural Orifice Transluminal Endoscopic Surgery (NOTES) is presented in this paper. It aims to tackle two crucial technical barriers which hinder its smooth transition from animal studies to clinical trials: providing effective instrumentations to perform complex NOTES procedures and maintaining the spatial orientation for endoscopic navigation. MATER...

PURPOSE Recently, an increase in well-differentiated rectal neuroendocrine tumors (WRNETs) has been noted. We aimed to evaluate transanal endoscopic microsurgery (TEM) for the treatment of WRNETs. METHODS Between December 1995 and August 2009, 109 patients with WRNETs underwent TEM. TEM was performed for patients with tumors sizes of up to 20 mm and without a lymphadenopathy. These patients h...

Robotics enables a variety of unconventional actuation strategies to be used for endoscopes, resulting in reduced trauma to the GI tract. For transmission of force to distally mounted endoscopic instruments, robotically actuated tendon sheath mechanisms are the current state of the art. Robotics in surgical endoscopy enables an ergonomic mapping of the surgeon movements to remotely controlled s...

BACKGROUND Biodegradable hydrogels can deliver therapeutic payloads with great potentials in EMR and endoscopic submucosal dissection (ESD) to yield improvements in efficacy and foster mucosal regeneration. OBJECTIVE To assess the efficacy of an injectable drug-eluting elastomeric polymer (iDEEP) as a submucosal injection material. DESIGN Comparative study of 3 different solutions by using ...

A 95-year-old Japanese woman presented to our hospital with intermittent vomiting and several episodes of melena. Abdominal computed tomography revealed intussusception of the gastric tumor into the duodenum. After endoscopic reduction, endoscopic ultrasonography identified a hypoechogenic lesion limited to the submucosal layer. Endoscopic resection was performed as a localized treatment for th...

Various surgical techniques, such as endoscopic surgery and robotic surgery, are developed to optimize the esthetic outcome even in operations for malignancy. A modified face-lift or retroauricular approach are used to minimize postoperative scarring. Recently, robot-assisted surgery is being done in various fields and considered as favorable treatment method by many surgeons. However its high ...

We report the case of an 83-year-old man with past medical history of hypertension who was initially referred for the evaluation of newly diagnosed squamous cell cancer (SCC) of the esophagus. An endoscopic ultrasound was performed and showed a medium-sized flat lesion in the mid-esophagus, which appeared to be invading the muscularis mucosa (T1a). During a multidisciplinary meeting, it was dec...

Patients with gastric tumors usually present with symptoms of discomfort or pain in the epigastrium, regurgitations, nausea, vomiting or melena. Treatment options include open and laparoscopic total or partial gastrectomy and recently endoscopic mucosal resection. A case of successful endoscopic submucosal dissection is described with the unusual pathological finding of heterotopic pancreatic t...
