BACKGROUND: The removal of obstacles from the surgical field is a crucial aspect of any procedure in gynecological, urological or visceral laparoscopic surgery. Reliable instruments and skilled assistance are essential for the smooth execution of procedures. Blunt forceps are commonly used to keep tissue away from the operating field. The range of existing instruments has been enhanced by the introduction of laparoscopic retractors. However, no laparoscopic retractor can be used without causing tissue damage...

The present study describes a novel all-arthroscopic technique for medial and lateral meniscal allograft transplantation (MAT). Surgical instruments were specifically designed to assist in the all-arthroscopic approach for MAT. The bone plug attachment technique, either the arthroscopic-assisted or all-arthroscopic approach, attaches bone plugs to the anterior and posterior horns. In the present study, two sets of surgical implements were designed: One to produce bone plugs of predefined sizes in the anterior and posterior horns of the allograft meniscus (bone plug implements) and a second to create bone tunnels in the receptor tibial plateau to hold the bone plugs (bone tunnel implements)...

Transnasal endoscopic dacryocystorhinostomy is a good alternative for external DCR. It is considered a safe and efficient technique with successful results, comparable or even better than the external technique. Advanced knowledge of the endoscopic anatomy and the lacrimal system is necessary to perform the procedure safely, and to obtain good surgical outcomes. The aim of the paper is to analyze the changes of the endoscopic technique and to improve it. The transnasal endoscopic dacryocystorhinostomy surgical technique is described in a "step by step" manner...

Aris Koryllos, Erich Stoelben
Bronchus sleeve resection for operative treatment of non-small cell lung cancer (NSCLC) is a gold standard in modern thoracic surgery in cases of centrally located tumors or hilär lymph node metastases. Advanced instruments and growing surgical experience allowed surgeons to reduce the required incisions (from 3-port to uniportal) and to resect larger and more centrally located malignancies minimal invasively. It is a logical and expected advance in thoracic surgery that video-assisted thoracoscopic surgery (VATS) would be ultimately used also for complex bronchial resections...

REVIEW
Hasan Fevzi Batirel
Minimally invasive surgical techniques are important in surgical management of thymic pathologies. Traditional access techniques are being replaced with minimally invasive techniques using multiportal or uniportal approach. Adoption of minimally invasive techniques for thymic malignancies has been slow due to long term recurrence concerns. Recent studies show that minimally invasive video-assisted thoracoscopic surgery (VATS) or robotic approach to early stage thymic malignancies are associated with less intraoperative bleeding, lower rate of respiratory complications, shorter chest tube duration and shorter hospital stay...

Hedyeh Ziai, James P Bonaparte
BACKGROUND: Nasal valve collapse is a common cause of nasal obstruction in otolaryngology practice. Common examination methods, such as the Cottle Maneuver and modified Cottle Maneuver are available. However, these methods are dichotomous and do not provide ordinal severity information. The Ottawa Valve Collapse Scale (OVCS) is a grading system for assessing and easily grading external nasal valve collapse in patients with a septal deviation. The primary objective was to assess the test-retest reliability and construct validity of the OVCS grading scale...

The molecular identification of species of interest is an important part of an imaging mass spectrometry (IMS) experiment. The high resolution accurate mass capabilities of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) have recently been shown to facilitate the identification of proteins in matrix-assisted laser desorption/ionization (MALDI) IMS. However, these experiments are typically limited to proteins giving rise to ions of relatively low m/z due to difficulties transmitting and measuring large molecular weight ions of low charge states...

BACKGROUND/PURPOSE: To describe a novel use of the flexible nitinol loop membrane scraper (FINESSE Flex loop; Alcon, Fort Worth, TX) for rescue and refixation of a dislocated intraocular lens (IOL). METHODS: A 27-gauge nitinol flex loop was used to lasso each haptic of a dislocated 3-piece IOL. By retracting the loop, the haptic could be effectively locked to the instrument and externalized through a scleral tunnel, thereby fixating it to the sclera in a sutureless fashion...

BACKGROUND: Inaccuracy of component alignment in total knee arthroplasty adversely impacts outcomes. Robotic systems improve translation of pre-operative planning to intra-operative steps, theoretically resulting in greater accuracy and precision. In this study we systematically review literature data of alignment outcomes and apply meta-analysis methods to assess whether robotic-assisted knee arthroplasty provides superior outcomes when compared to conventional knee prostheses. METHODS: A PRISMA compliant search comparing alignment outcomes in robotic vs conventional knee arthroplasty was performed...

Robot-assisted surgery is of growing interest in the surgical and engineering communities. The use of robots allows surgery to be performed with precision using smaller instruments and incisions, resulting in shorter healing times. However, using current technology, an operator cannot directly feel the operation because the surgeon-instrument and instrument-tissue interaction force feedbacks are lost during needle insertion. Advancements in force feedback and control not only help reduce tissue deformation and needle deflection but also provide the surgeon with better control over the surgical instruments...

Single-cell RNA-seq reveals the cellular heterogeneity inherent in the population of cells, which is very important in many clinical and research applications. Recent advances in droplet microfluidics have achieved the automatic isolation, lysis, and labeling of single cells in droplet compartments without complex instrumentation. However, barcoding errors occurring in the cell encapsulation process because of the multiple-beads-in-droplet and insufficient throughput because of the low concentration of beads for avoiding multiple-beads-in-a-droplet remain important challenges for precise and efficient expression profiling of single cells...
