Multivariate singular spectrum analysis (M-SSA) was recently adapted to study systems of coupled oscillators. It does not require an a priori definition for phase nor detailed knowledge of the individual oscillators, but it uses all the variables of each system. This aspect could be restrictive for practical applications, since usually just a few (sometimes only one) variables are measured. Based on dynamical systems and observability theories, we first show how to apply the M-SSA with only one variable and show the conditions to achieve good performance...

Background: Surgical trauma triggers an important postoperative stress response characterized by significantly elevated levels of cytokines, an event that can favor the emergence of immune disorders which lead to disturbances in the patient's body defense. The magnitude of postoperative stress is related to the degree of surgical trauma. Aim: To evaluate the expression of pro-inflammatory (TNF-α, IFN-γ, IL-1β, and IL-17) and anti-inflammatory (IL-4) cytokines in patients submitted to conventional and single-port laparoscopic cholecystectomy before and 24 h after surgery...

OBJECTIVE: To evaluate a new magnetic surgical system during reduced-port laparoscopic cholecystectomy in a prospective, multicenter clinical trial. BACKGROUND: Laparoscopic instrumentation coupled by magnetic fields may enhance surgeon performance by allowing for shaft-less retraction and mobilization. The movements can be performed under direct visualization, generating different angles of traction and reducing the number of trocars to perform the procedure. This may reduce well-known associated complications of trocars, including incisional pain, scarring, infection, bowel, and vascular injuries, among others...

The concept of complete mesocolic excision and central vascular ligation for colonic cancer has been recently introduced. The paper describes a technique of right-sided complete mesocolic excision and intracorporeal anastomosis by using a single-port robotic approach with an additional conventional robotic port. We performed a single-port plus an additional port robotic surgery using the Da Vinci Single-Site platform via the Pfannenstiel incision and the wristed robotic instruments via an additional robotic port in the left lower quadrant...

PURPOSE: Laparoscopic surgery was previously accepted as an alternative surgical option in treatment for colorectal cancer. Nowadays, single-port laparoscopic surgery (SPLS) is introduced as a method to maximize advantages of minimally invasive surgery. However, SPLS has several limitations compared to conventional multiport laparoscopic surgery (CMLS). To overcome those limitations of SPLS, reduced port laparoscopic surgery (RPLS) was introduced. This study aimed at evaluating the short-term outcomes of RPLS...

BACKGROUND: Single-incision laparoscopic colectomy (SILC) requires only one umbilical port site and (depending on technique) a specimen extraction site. The aim of this study was the assessment of the available evidence for the comparison of SILC to conventional multi-port laparoscopic colectomy (MLC) in adult patients, in whom elective colectomy is indicated because of malignant or benign disease. First, previous meta-analyses on this topic were assessed. Secondly, a systematic review and meta-analysis of randomised controlled trials, was performed...

In Korea, proximal gastrectomy has recently attracted attention as a better choice of function-preserving surgery for proximal early gastric cancer than total gastrectomy. Of the various strategies to overcome reflux symptoms from remnant stomach, double tract reconstruction not only reduces the incidence of anastomosis-related complications, but is also sufficiently reproducible as a laparoscopic procedure. Catching up with the recent rise of single-port laparoscopic surgeries, we performed a pure single-port laparoscopic proximal gastrectomy with DTR...

In this study, a novel operating strategy was developed to improve the separation performance of simulated moving bed (SMB) chromatography by the simultaneous control of product outlet streams and feed inlet stream (SimCon). The SimCon operation can achieve a high separation performance without exceeding the maximum allowable pressure drop in an SMB system. The SimCon operation consisted of three steps within a single switching period: the initial, middle, and last steps. The extract port and feed-inlet port were closed at the initial step, but the raffinate port was closed at the last step...
