In this opinion paper of the Journal of Endocrinological Investigation, leading experts in the field report on their current clinical experience with a novel approach for thyroid gland surgery, namely, "transoral thyroidectomy" (TOT). This feasible and novel surgical procedure does not require visible incisions and is, therefore, a truly scarless surgery. Patients meeting the following criteria can be considered as candidates for TOT: (a) an ultrasonographically (US) estimated thyroid diameter ≤10 cm; (b) US-estimated gland volume ≤45 mL; (c) nodule size ≤50 mm; (d) presence of a benign tumor such as a thyroid cyst or a single- or multi-nodular goiter; (e) Bethesda 3 and/or 4 category and (f) papillary microcarcinoma without the evidence of metastasis...

This study evaluated the feasibility and safety of robotic single port hysterectomy and laparoscopic single port hysterectomy, and to compare the perioperative parameters of the two systems. Twenty patients underwent robotic single port hysterectomy and 25 patients underwent laparoscopic single port hysterectomy. All hysterectomies were successfully performed via a single port and there were no conversions to conventional multi-port laparoscopy, multi-port robotic, open surgery, or vaginal surgery. The median operative time and hysterectomy time in robotic and laparoscopic groups were 90 vs...

In the emergency care field, early treatment of acute heart or respiratory failure has been a global concern. In severe cases, patients are frequently required to be on an extracorporeal membrane oxygenator (ECMO) life support. To make the ECMO system more compact and portable, we proposed a sequential flow-type centrifugal pump named the sequential flow pump (SFP). In this study, principle and basic properties of this novel blood pump were examined by computational fluid dynamic (CFD) analysis and an experimental model...

Endowing tele-manipulation frameworks with the capability to accommodate a variety of robotic hands is key to achieving high performances through permitting to flexibly interchange the end-effector according to the task considered. This requires the development of control policies that not only cope with asymmetric master-slave systems but also whose high-level components are designed in a unified space in abstraction from the devices specifics. To address this dual challenge, a novel synergy port is developed that resolves the kinematic, sensing, and actuation asymmetries of the considered system through generating motion and force feedback references in the hardware-independent hand postural synergy space...

INTRODUCTION: Minimally invasive surgery is the treatment of choice in early-stage lung cancer. However, experience in infectious lung disease, primarily bronchiectasis, is limited probably because of the presence of dense pleural adhesions, multiple lymph nodes, and spiral bronchial arteries. The present study shows our experience of video-assisted thoracoscopic surgery (VATS) lobectomy and segmentectomy in the treatment of bronchiectasis. MATERIALS AND METHODS: Patients who underwent VATS lobectomy or segmentectomy in our clinic between April 2008 and 2015 were retrospectively evaluated...

PURPOSE: Vascular lip anomalies include infantile hemangiomas, venous malformations, and arteriovenous malformations. Surgical management can be complicated by alterations in horizontal length, vertical height, and lip thickness from the underlying pathology. Additional reconstructive challenges include preservation of oral continence, vermillion definition, and the sublabial sulcus. This report describes a technique of supramaximal single-stage full-thickness wedge resection of these lesions...

We describe a technique for the penetrating keratoplasty (PKP) triple procedure that uses 29-gauge dual-chandelier illumination during creation of a non-open-sky continuous curvilinear capsulorhexis (CCC). The chandeliers are inserted through the pars plana into the vitreous cavity through the bulbar conjunctiva at the 3 o'clock and 9 o'clock positions. We compared this approach with that of a core vitrectomy, in which a single 25-gauge port is inserted into the vitreous cavity transconjunctivally through the upper temporal pars plana...

BACKGROUND AND OBJECTIVES: Postoperative adhesions occur less often in laparoscopies than in laparotomies, but the incidence can be reduced further. Seprafilm, a sodium hyaluronate/carboxymethylcellulose absorbable barrier, was developed to prevent adhesions after abdominal surgery, and is approved for postoperative adhesion prevention. However, Seprafilm is seldom used in laparoscopic surgery because of its tendency to break apart when it is inserted into the abdominal cavity through a trocar, resulting in a high placement failure rate...

Approximately two decades ago, thoracic surgery witnessed the leap from thoracotomy to the first video-assisted thoracic surgery (VATS) lobectomy. Minimally invasive lobectomy and hilar lymphadenectomy is now widely established as a safe and oncological sound technique that is the standard of care for early-stage lung cancer. The move toward less invasive surgery has no doubt driven the innovation of sophisticated instruments and technology to cope with the demanding need of working through a restricted incision...

BACKGROUND: Patients receiving noninvasive ventilation (NIV) may benefit from medical aerosol, but most guidance on dosing with different aerosol devices is limited to in-vitro studies. The study was designed to in-vitro, ex-vivo, and in-vivo compare aerosol delivery during bilevel NIV with three types of aerosol generators: metered dose inhaler with AeroChamber-MV spacer (AC), Aerogen Pro vibrating mesh nebulizer (PRO), and Sidestream jet nebulizer (SIDE). MATERIALS AND METHOD: A bilevel ventilator with dry single limb circuit and fixed expiratory port was set in spontaneous mode with initial inspiratory and expiratory pressures of 20 and 5 cmH20, 1:3 inspiratory-expiratory ratio, and 15 breaths...

We report our experience with single-port and multiple-port laparoscopic myomectomy with operative outcomes and surgical skills. Hundred consecutive patients underwent single-port laparoscopic myomectomy (SP-LM) and 69 multi-port laparoscopic myomectomy (MP-LM). The operative outcomes were compared between the two methods. All procedures were successfully completed without conversion to abdominal myomectomy. The mean maximum diameter of the largest myoma was 7.4 (5-13) vs. 6.8 (5-12) cm and the mean number of myomas was 1...

BACKGROUND: Despite its evident clinical benefits, single-incision laparoscopic surgery (SILS) imposes inherent limitations of collision between external arms and inadequate triangulation because multiple instruments are inserted through a single port at the same time. METHODS: A robot platform appropriate for SILS was developed wherein an elbowed instrument can be equipped to easily create surgical triangulation without the interference of robot arms. A novel joint mechanism for a surgical instrument actuated by a rigid link was designed for high torque transmission capability...
