AIMS: Single-incision vaginal mesh (SIVM) procedures for pelvic organ prolapse (POP) differed in mesh fabrication and implantation that may affect treatment outcomes. We aim to evaluate and compare the safety and effectiveness of two SIVM procedures, and explore factors that may have associations with surgical effectiveness. METHODS: Our data of using two SIVM procedures for a total (anterior and posterior) vaginal mesh repair were studied. Patients who had ≧stage 2 POP and underwent either Elevate (n = 85) using anchored, lightweight meshes or Prosima procedures (n = 95) using non-anchored, original meshes were assessed...

INTRODUCTION: The aim of this review is to provide a general historical and contemporary perspective on the implementation and use of robot-assisted laparoscopy in gynecology as well as the experience gained to date. CONTENTS: Robotic-assisted laparoscopic surgeries in gynecology include benign hysterectomy, myomectomy, radical hysterectomy, lymph node dissections or sacrocolpopexies. Robot-assisted gynecologic surgery is often associated with longer operating room time but generally similar clinical outcomes, decreased blood loss and shorter hospital stay when compared to open or laparoscopic surgery...

Sir Harold Gillies first described rotating a band of temporalis muscle over the zygoma where the muscle sling was augmented with strips of fascia lata to rehabilitate facial paralysis (1) . McLaughlin later modified this technique in the 1950s without inversion of the temporal muscle but in an orthodromic manner thus avoiding the soft tissue fullness over the zygomatic arch area and depression of the donor site (2) . Although several refinements of this technique have been described, all required skin incisions on the face until a transoral technique was described recently by this clinical group (3) ...

BACKGROUND: Situs inversus totalis is a rare autosomal disorder in which the patient's affected visceral organs are a perfect mirror image of their normal positions. Surgery in these patients is technically challenging. Minimally invasive surgery such as laparoscopic cholecystectomy is the standard treatment for symptomatic cholelithiasis, but it can be difficult to perform. Laparoscopic cholecystectomy in patients with situs inversus totalis may be even more technically challenging. Fluorescence cholangiography is a new innovation in the field of navigation surgery...

BACKGROUND: Knowing the three-dimensional (3D) structure of the chromatin is important for obtaining a complete picture of the regulatory landscape. Changes in the 3D structure have been implicated in diseases. While there exist approaches that attempt to predict the long-range chromatin interactions, they focus only on interactions between specific genomic regions - the promoters and enhancers, neglecting other possibilities, for instance, the so-called structural interactions involving intervening chromatin...

OBJECTIVE: Open surgical approaches to treat tibial avulsion fractures of the posterior cruciate ligament (PCL) often use large incisions involving extensive muscle dissection and retraction. The objective of this study was to describe a new mini-invasive approach targeting the fractured zone, to minimize surgical dissection and improve recovery and rehabilitation. METHODS: The new approach was used in 15 males and seven females with isolated PCL avulsions. The length of the surgical incision, surgical time, need for conversion to open technique, visual analog scores (VAS) and duration of hospital stay were studied to assess the efficacy, learning curve and advantages of the new technique...

BACKGROUND: Transurethral resection of the prostate (TURP) has been the standard operation for benign prostatic obstruction (BPO) for 40 years, with approximately 25,000 procedures performed annually, and has remained largely unchanged. It is generally a successful operation, but has well-documented risks for the patient. Thulium laser transurethral vaporesection of the prostate (ThuVARP) vaporises and resects the prostate using a surgical technique similar to TURP. The small amount of study data currently available suggests that ThuVARP may have certain advantages over TURP, including reduced blood loss and shorter hospital stay, earlier return to normal activities, and shorter duration of catheterisation...
