BACKGROUND: With increasing experience and technological advancement in surgical instruments, surgeons have explored the feasibility of single-incision laparoscopic surgery and natural orifice transluminal endoscopic surgery (NOTES). These techniques aim to further reduce surgical trauma, but are not popular due to their inherent pitfalls including clashing of instruments, lack of counter traction, lengthy operating time, and so on. A novel surgical robotic system was designed to overcome the limitations of the existing technologies...

BACKGROUND: Giant inguinoscrotal hernias (GIH) are defined as groin hernias extending below the mid-thigh when standing, often significantly encumbering activities of daily living. To date, there are no reports utilizing the combination of progressive pneumoperitoneum (PPP), botulinum toxin A injection (BTI), and enhanced view-totally extraperitoneal (eTEP) technique for GIH repair. In this report, we present 2 such cases of this unique minimally invasive multidisciplinary approach to address GIH...

The use of surgical treatment for refractory isolated gastric varices has decreased owing to the development of endoscopic and radiologic procedures, although surgeries are sometimes required as the final method. A 75-year-old Japanese woman was diagnosed with solitary gastric varices. Initially, intraoperative splenic artery embolization was performed using the balloon transcatheter technique under general anesthesia. Laparoscopic splenectomy was performed safely owing to preoperative splenic artery embolization...

BACKGROUND: Intraoperative ureteral injury is rare, but a grave complication during laparoscopic surgery. Several methods for intraoperative localization of ureters are described with their own pitfalls. Intraoperative localization using near-infrared (NIR) fluorescence with indocyanine green (ICG) is an easier and assured method during laparoscopic pelvic surgeries. METHOD: From September 2017 to December 2017, patients undergoing laparoscopic pelvic surgeries were administered cystoscopic-guided intraureteral ICG immediately preoperatively with tip of a 6-Fr ureteral catheter...

Botulinum neurotoxin-A and botulinum neurotoxin-B have been shown to play a potential role in improving flap survival in animal models. The aim of this study is to review indications as well as to study injection timing, technique, and doses of botulinum neurotoxin-A and botulinum neurotoxin-B in animal models. Seventeen articles describe a total of 266 animals that underwent botulinum toxin injections before or during flap harvesting or vascular anastomosis procedure. All the studies demonstrated a beneficial effect of botulinum toxin administration in flap surgery or vascular anastomosis...

INTRODUCTION: Tension-free hernia repair has been regarded as a gold standard treatment for selected inguinal hernias, but the use of prosthetic mesh in acute incarcerated inguinal hernias is controversial. Our study focused on evaluating the safety and efficacy of the prosthetic mesh repair for emergency cases. METHODS: Patients with acute incarcerated inguinal hernias who underwent emergency prosthetic mesh repair during 2009 to 2014 at our department were included...

PURPOSE: We utilized a novel approach of combined photochemical tissue bonding (PTB) and human amniotic membrane (HAM) to improve hand tendon repair and also evaluated its efficacy. METHODS: Subei chickens underwent surgical transection of the flexor digitorum profundus tendons and repair by (1) SR (standard Kessler suture; n = 24; 6-0 prolene) and (2) HAM/PTB (n = 24), where a section of HAM was stained with 0.1% Rose Bengal, wrapped around the ruptured tendon and bonded with 532 nm light (0...

OBJECTIVES: Video-assisted thoracoscopic surgery (VATS) pulmonary segmentectomy is commonly used in treating small ground-glass opacity (GGO) nodules in lung. The identification of the intersegmental plane is one of the challenges. In this pilot study, we aimed to evaluate the feasibility of indocyanine green (ICG) angiography in VATS segmentectomy. METHODS: Nineteen GGO patients were enrolled, and VATS segmentectomy with ICG near-infrared angiography were performed between July 2017 and December 2017...

INTRODUCTION: The objective of this study was to compare the placement of ablation needles using 3-dimensional electromagnetic-guided ultrasound (guided) to standard ultrasound guidance (standard) in both laparoscopic surgery and open surgery. Endpoints for this study included targeting accuracy and number of required needle withdrawals and reorientations. METHODS: Using a porcine model, fiducial markers were placed into the kidney and liver to represent tumors...

OBJECTIVE: The introduction of advanced endoscopic systems, such as the Storz Image1S and the Olympus Endoeye, heralds a new era of 3-dimensional (3D) visualization. The aim of this report is to provide a comprehensive overview of the neurophysiology of 3D view, its relevance in videoscopy, and to quantify the benefit of the new 3D technologies for both rigid and articulated instruments. METHOD: Sixteen medical students without any laparoscopic experience were trained each for a total of 27 hours...

BACKGROUND: Virtual reality (VR)-based simulations offer rich opportunities for surgical skill training and assessment of surgical novices and experts. A structured evaluation and validation process of such training and assessment tools is necessary for effective surgical learning environments. OBJECTIVE: To develop and apply a classification system of surgeon-reported experience during operation of a VR vertebroplasty simulator. METHODS: A group of orthopedic, trauma surgeons and neurosurgeons (n = 13) with various levels of expertise performed on a VR vertebroplasty simulator...

BACKGROUND: The main limitation of perfusion assessment with indocyanine green fluorescence angiography during colorectal surgery is that the surgeon assesses the quality of perfusion subjectively. The ideal intestinal viability test must be minimally invasive, objective, and reproducible. We evaluated the quantitativity and reproducibility of laser speckle contrast imaging for perfusion assessment during colorectal surgery. METHODS: This was a prospective, nonrandomized, pilot study of 8 consecutive patients who underwent elective left-sided colorectal resection...

BACKGROUND: Nowadays, minimally invasive video-assisted thyroidectomy (MIVAT) is considered a safe and effective option. However, its complication rate has not been specifically discussed yet. The aim of this systematic review was enrolling a large number of studies to estimate early and late complications (transient and definitive, uni- and bilateral laryngeal nerve palsy; transient and definitive hypocalcemia; cervical hematoma; hypertrophic or keloid scar) of MIVAT compared with conventional technique...

INTRODUCTION: With the availability of low-cost head-mounted displays (HMDs), virtual reality environments (VREs) are increasingly being used in medicine for teaching and clinical purposes. Our aim was to develop an interactive, user-friendly VRE for tridimensional visualization of patient-specific organs, establishing a workflow to transfer 3-dimensional (3D) models from imaging datasets to our immersive VRE. MATERIALS AND METHODS: This original VRE model was built using open-source software and a mobile HMD, Samsung Gear VR...
