Masaki Tanito
Trabeculotomy (LOT) is performed to reduce the intraocular pressure in patients with glaucoma, both in children and adults. It relieves the resistance to aqueous flow by cleaving the trabecular meshwork and the inner walls of Schlemm's canal. Microhook ab interno LOT (µLOT), a novel minimally invasive glaucoma surgery, incises trabecular meshwork using small hooks that are inserted through corneal side ports. An initial case series reported that both µLOT alone and combination of µLOT and cataract surgery normalize the intraocular pressure during the early postoperative period in Japanese patients with glaucoma...

BACKGROUND: Recurrence of inverted papilloma (IP) is a problem in 12-17% of tumors. Controversy exists regarding benefits of intraoperative frozen section histopathology (IFSH) for IP resection; however, to our knowledge, no study has specifically investigated this. IFSH for IP resection is the standard of care in our practice. We, therefore, reviewed our outcomes of using IFSH for IP resection. A secondary goal was to assess the reliability of IFSH. METHODS: Patients with IP who underwent surgical resection (2010-2016) with minimum 9-month follow-up were included...

OBJECTIVE: We describe laparoscopic transdiaphragmatic (LTD) chest surgery without intercostal incisions and focus on technique and safety. The goal of LTD is to minimize postoperative pain. METHODS: We reviewed all patients undergoing LTD chest surgery (September 8, 2010-April 4, 2017). We place 4 abdominal ports with the patient in semilateral decubitus, make 2 diaphragmatic openings, and advance 2 ports into the chest. The intrathoracic operation is standard video-assisted thoracoscopic surgery (VATS), and diaphragmatic openings are closed at the end...

PURPOSE: To evaluate the safety, efficacy and merits of laparoscopic repair in children with hydroceles by comparing the outcomes of laparoscopic repair and the traditional open repair (OR) procedure. The outcomes of the following three laparoscopic percutaneous extra-peritoneal closure (LPEC) approaches were also compared: conventional two-port surgery, transumbilical single-site two-port surgery and single-port surgery. METHODS: We retrospectively compared the demographic, perioperative and follow-up data from the consecutive records obtained for 382 boys who underwent OR and 950 boys who underwent LPEC at two children's medical centres in China...

BACKGROUND: During cardiopulmonary bypass (CPB) in children, anesthesia maintained by sevoflurane administered via the oxygenator is increasingly common. Anesthetic uptake and requirement may be influenced by the non-physiological conditions during hypothermic CPB. Narcotrend-processed EEG monitoring may, therefore, be useful to guide the administration of sevoflurane during this phase. OBJECTIVE: The objective of this prospective, clinical, observational study was to assess the correlation between body temperature, Narcotrend Index (NI) and administered sevoflurane in children during CPB...

INTRODUCTION: Single-port thoracoscopic surgery has widened the current minimally invasive surgical techniques toward more less invasive procedures in terms of reducing the number of incisions. However, the current status of oncologic outcome with this technique is not well known for lung cancer surgery. The purpose of this study is to evaluate the oncologic outcomes in early stage lung cancer for impact of the survival outcomes with our experience of conversion to a single-port approach from the conventional three-port approach...

OBJECTIVES: The Blalock-Taussig shunt (BTS) operation is a cornerstone as initial palliative surgery for congenital heart disease with severely reduced pulmonary blood flow (PBF). The ideal PBF provided by BTS is crucial for an uneventful postoperative course, since excess PBF results in acute distress of the systemic circulation and insufficient PBF requires another BTS surgery. Therefore, the goal of this study was to develop a simple device to control the shunt graft flow percutaneously using a constrictor balloon connected to a subcutaneous port...

Background: Trocar-site hernia (TSH) is an uncommon complication following laparoscopic surgery and a potential cause of significant morbidity if bowel incarceration or strangulation occurs. Lateral trocar sites are intrinsically less susceptible to hernia development and traditionally do not mandate fascial closure. We present an unusual case involving an incarcerated TSH from a 12-mm right lateral port after robotic prostatectomy. Case Presentation: The patient is a 76-year-old man with localized intermediate risk, high-volume prostate cancer who underwent a robot-assisted, laparoscopic prostatectomy...

BACKGROUND: Energy-based devices are used in nearly every laparoscopic operation. Radiofrequency energy can transfer to nearby instruments via antenna and capacitive coupling without direct contact. Previous studies have described inadvertent energy transfer through bundled cords and nonelectrically active wires. The purpose of this study was to describe a new mechanism of stray energy transfer from the monopolar instrument through the operating surgeon to the laparoscopic telescope and propose practical measures to decrease the risk of injury...

The management of hemothorax (spontaneous or, more often, due to thoracic trauma lesions), follows basic tenets well-respected by cardiothoracic surgeons. In most, a non-operative approach is adequate and safe, with a defined group of patients requiring only tube thoracostomy. Only a minority of patients need a surgical intervention due to retained hemothorax, persistent bleeding or incoming complications, as pleural empyema or entrapped lung. In the early 1990s, the rapid technological developments determined an increase of diagnostic and therapeutical indications for multiport video-assisted thoracoscopic surgery (VATS) as the gold standard therapy for retained and persistent hemothorax, allowing an earlier diagnosis, total clots removal and better tubes placement with less morbidity, reduced post-operative pain and shorter hospital stay...

REVIEW
Luca Bertolaccini, Alessandro Pardolesi, Jury Brandolini, Piergiorgio Solli
The last British Society of Thoracic Surgeons guidelines of 2010 for the management of primary spontaneous pneumothorax (PSP) stated that, after the first recurrence, the treatment of PSP should be a surgical operation, like a bullectomy accompanying with a procedure for inducing pleural adhesions. Therefore, the surgical approach is considered the best treatment to minimise the risk of recurrence in patients who experienced a PSP. There is substantial evidence in the literature demonstrating that the minimally invasive approach should be preferred to the thoracotomic procedure since it can reduce the postoperative pain and it is associated with a faster recovery of the physical and working activity...

REVIEW
Eliseo Passera, Gaetano Rocco
Over the last two decades, conventional video-assisted thoracic surgery (VATS) has established itself as the preferred approach for almost all thoracic surgical procedures. The procedure provides a safe and easy approach with undisputed patient benefit at a cost acceptable to the healthcare system all over the world, in large hospitals as well as underprivileged rural areas. VATS has effectively addressed the patients' right to less scarring, trauma (both of access and intrathoracic manipulation), medication, pain, hospitalization, and early return home and work...

REVIEW
Omar I Ramadan, Benjamin Wei, Robert J Cerfolio
Minimally invasive thoracic surgery, when compared with open thoracotomy, has been shown to have improved perioperative outcomes as well as comparable long-term survival. Robotic surgery represents a powerful advancement of minimally invasive surgery, with vastly improved visualization and instrument maneuverability, and is increasingly popular for thoracic surgery. However, there remains debate over the best robotic approaches for lung resection, with several different techniques evidenced and described in the literature...
