BACKGROUND: A recent meta-analysis and systematic review suggested that single-incision laparoscopic cholecystectomy (SILC) had a higher procedure failure rate with more blood loss and that it required a longer surgical time than conventional laparoscopic cholecystectomy. Herein, we introduce our experience with the needlescopic grasper-assisted and bendable retractor-assisted SILC technique and evaluate its safety and sustainability. METHODS: The present retrospective cohort study included 407 Japanese patients who underwent needlescopic grasper-assisted and bendable retractor-assisted SILC between January 2012 and April 2017 at our institution...

Background: rigid trocars are widely adopted in video-assisted thoracic surgery (VATS), despite some disadvantages: (I) cannula strong pressure on intercostal nerve stimulating postoperative pain; (II) limited movement of thoracoscopic devices on their fulcrum when extreme acute angles with the chest wall are needed. Wound retractor (WR) device, designed for laparoscopic surgery, it is also used in VATS, but to protect mini-thoracotomy. We compared the use of extra-small WR versus rigid trocar at camera port that is the most painful thoracostomy...

The envelope is constantly being pushed to minimize the invasiveness of prostate cancer surgery without compromising oncologic or functional outcomes. Transperitoneal robot-assisted radical prostatectomy has certainly accomplished these goals. However, it is our intent to push the envelope even further, that is, to minimize the invasiveness of already minimally invasive surgery. To accomplish this lofty goal, we borrowed the transperineal approach from open surgery and fused it with the latest robotic technology to innovate an extraperitoneal robotic prostatectomy technique that is less invasive than the traditional robotic technique...

INTRODUCTION AND OBJECTIVES: Transumbilical laparoendoscopic (LESS) procedures reduce access trauma. Laparoendocopic single-incision triangulated umbilical surgery (SITUS) utilizes straight instruments in a triangulated fashion, via three trocars placed through a single umbilical incision. METHODS: Thirty-two consecutive patients underwent an SITUS pyeloplasty. Access is performed by incision of the umbilical fold by 3/4 of its circumference, a 5-mm camera port, and consequently, cranial and caudal 3 or 5 mm working trocars are placed at a distance of 3-6 cm, thus allowing triangulation...

REVIEW
Truman Cheng, Calvin S H Ng, Zheng Li
In the past three decades, rod lens endoscopes had facilitated the development and wide spread applications of video-assisted thoracic surgery (VATS). With the rise of uniportal VATS in recent years, innovations in surgical instruments should once again complement the advancement in surgical technique. While articulated flexible endoscopes have expand the field of view, and can alter viewing direction with minimal maneuvers, they still suffer from problems like trocar crowding and interference with other instruments...

BACKGROUND: Reduced port laparoscopic surgery (RPLS) is comparable to conventional multiport laparoscopic surgery and has the potential to provide improved cosmesis and decreased pain; as such, it satisfies a growing demand for less invasive surgical procedures. Moreover, a zigzag incision of the umbilicus results in a less visible scar in plastic surgery. Here we report a series of two cases with bilateral organ tumors treated by single-stage RPLS using a combination of a transumbilical approach and a zigzag incision...

Coronary artery bypass surgery is most commonly performed using a hand-sewn technique with a continuous monofilament suture. The C-Port distal anastomotic device is a miniature stapler designed to create an arteriotomy and attach the graft to the coronary artery all in one step. It is the only distal coronary anastomotic device currently approved for clinical use and can be useful in facilitating less invasive coronary surgery. This report examines the histological attributes of such an anastomosis in a patient who underwent heart transplantation approximately 1 year after robotic totally endoscopic stapled coronary bypass using the C-Port anastomotic device...
