INTRODUCTION: The electrothermal bipolar vessel-sealing device (BVSD) is known to supply a strong vessel-sealing power. However, only few studies have reported lymph node dissection (LND) using only BVSD during laparoscopic surgery for gastric cancer. The purpose of this study was to investigate the feasibility of LND using BVSD during reduced port laparoscopic distal gastrectomy for gastric cancer. METHODS: From May 2015, patients in whom three- or single-port laparoscopic distal gastrectomy had been engaged for gastric cancer were enrolled in this study...

BACKGROUND: To date a variety of teleoperated surgical robotic systems have been developed to improve a surgeon's ability to perform demanding single-port procedures. However typical large systems are bulky, expensive, and afford limited angular motion, while smaller designs suffer complications arising from limited motion range, speed, and force generation. This work was to develop and validate a simple, compact, low cost single site teleoperated laparoendoscopic surgical robotic system, with demonstrated capability to carry out basic surgical procedures...

The aim of this meta-analysis was to evaluate if the advantages of single-incision laparoscopic surgery (SILS) to perform a colorectal resection justify a broad application of this approach. A total of 32 studies including 3863 patients, comparing colorectal procedures performed with SILS or multi-port laparoscopy (LCS) were analyzed after a systematic review. Colorectal SILS had comparable outcomes to multi-port LCS in terms of operating time (P = 0.44), conversion rate (2.0% vs 3.0%; P = 0.52), reoperations (1...

Laparoscopic distal pancreatectomy is regarded as safe and effective surgical approach in benign and low-grade malignant tumor of the pancreas. With the advances of laparoscopic techniques and instruments, many efforts to reduce the number of the trocar site has been made. There are a few available surgical techniques of laparoscopic single-site (single port or reduced port) distal pancreatectomy, suggesting its safety and feasibility. However, it is true that laparoscopic single-site distal pancreatectomy is difficult and technically quite demanding...

OBJECTIVE: Single-surgeon cohorts assessing robotically assisted video-assisted thoracic (RA-VATS) lobectomy have reported good outcomes, but there are little data regarding multiple surgeons applying a standard technique in separate hospitals. The purpose of this study was to show how a standardized robotic technique is both safe and reproducible between surgeons and institutions. METHODS: From July 1, 2012, to October 1, 2013, patients undergoing RA-VATS lobectomy for both benign and malignant disease were identified from a prospectively collected database of two thoracic surgeons from different hospitals within the same healthcare system and retrospectively analyzed...

A classical fullerene is composed of hexagons and pentagons only, and its stability is generally determined by the Isolated-Pentagon-Rule (IPR). Herein, high-temperature chlorination of a mixture containing a classical IPR-obeying fullerene C88 resulted in isolation and X-ray crystallographic characterization of non-IPR, nonclassical (NC) fullerene chloride C84(NC2)Cl30 (1) containing two heptagons. The carbon cage in C84(NC2)Cl30 contains 14 pentagons, 12 of which form two pairs of fused pentagons and two groups of quaternary sequentially fused pentagons, which have never been observed in reported carbon cages...

The EndoGrab™ Port-Free Endocavity Retractor is an internally anchored retracting device that enables surgeons to reduce not only the number of ports and incisions but also the number of assistant surgeons. Our institution performs single-incision laparoscopic colectomy (SILC) as a routine procedure. Forty-nine patients underwent a single-incision laparoscopic right hemicolectomy. In this procedure, we use this retractor to the mesenteric tissue, including the ileocolic vessels and the mesentery of the transverse colon, and overcame the technical problems related to SILC and showed excellent short-term outcomes...

INTRODUCTION: Single-port laparoscopic surgery has some technical limitations with respect to control of the forceps inserted through the single-access site, which results in increased internal collisions due to coaxial alignment of the instruments, as well as and decreased range of motion and visualization. To overcome these limitations, we employ a "modified marionette technique" as a way to carry out laparoscopic colorectal surgery. Materials and Surgical Technique: The procedures for the modified marionette technique are performed as follows: An Internal Organ Retractor (IOR)™ and an atraumatic clip designed to firmly grasp tissue, with 1-0 nylon thread, are inserted through a 12-mm trocar and secured in place where adequate visualization and traction for cutting with a radio knife is required...

Prostate tumors are graded by the revised Gleason Score (GS) which is the sum of the two predominant Gleason grades present ranging from 6-10. GS 6 cancer exclusively with Gleason grade 3 is designated as low grade (LG) and correlates with better clinical prognosis for patients. GS >7 cancer with at least one of the Gleason grades 4 and 5 is designated as HG indicate worse prognosis for patients. Current transrectal ultrasound guided prostate biopsies often fail to correctly diagnose HG prostate cancer due to sampling errors...

Robotic assisted laparoscopy pyeloplasty (RALP) has been associated with shorter recovery, less pain and improved cosmesis. To minimize visible scars, the hidden incision endoscopic surgery (HIdES) trocar placement has been previously developed. Our aim was to compare outcomes between the HIdES and traditional port placement (TPP) for pediatric RALP. A retrospective study was performed on patients under 15 years of age who underwent RALP at a single institution between August 2011 and November 2013. Patient demographics, intraoperative details, narcotic administration, and complications were reviewed...

Autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEP) flap has become increasingly popular because of its unique advantages. However, compared with some other forms of abdominal-based autologous reconstruction, DIEP flaps are associated with an increased risk of venous congestion. Many techniques-or lifeboats-have been introduced to diagnose and treat this potentially devastating complication. In this case report, we describe a novel strategy to augment venous drainage when venous congestion is encountered...
