Diagnostic Value of Endotoxin Activity for Acute Postoperative Complications: A Study in Major Abdominal Surgery Patients.

: Endotoxin, a component of lipopolysaccharide (LPS) from bacteria, disrupts the immune system, potentially leading to multiorgan failure. Unlike previous studies, we enrolled patients with mild clinical conditions after major abdominal surgery and assessed the predictive value of endotoxin activity (EA) levels for acute complications which occur within 7 days postoperatively. Also, the differential diagnostic value of EA was assessed in a subgroup of patients with abnormal liver function during the immediate postoperative period.

Effect of rigorous fluid management using monitoring of ECW ratio by bioelectrical impedance analysis in critically ill postoperative patients: A prospective, single-blind, randomized controlled study.

Background & Aims: Precise assessment of postoperative volume status is important to administrate optimal fluid management. Bioelectrical impedance analysis (BIA) which measures the body composition using electric character. Extracellular water (ECW) ratio by BIA represented as the ratio of ECW to total body water (TBW) and is known to reflect the hydration status.

The clinical efficacy and suitable implementation of two extracorporeal blood purification therapies: AN69-oXiris versus PMX-HP.

Purpose: In septic shock patients, pathogens and excessive endotoxins continuously overstimulate the host's immune system with a cytokine storm that can lead to multi-organ failure and even mortality. Various types of extracorporeal blood purification treatments have recently been introduced to remove excessive endotoxins and cytokines. Herein, we compared the clinical efficacy of two blood purification methods, PMX-HP and AN69-oXiris, and discussed their detailed indications according to disease severity.

Venous-to-arterial carbon-dioxide tension difference as a useful predictor of patient prognosis after major surgery.

Purpose: Change in venous-to-arterial carbon dioxide partial pressure difference[P(v-a)CO] could be a useful marker to assess tissue perfusion status. Herein, we assessed the predictive values of postoperative P(v-a)CO measurements for mortality in critically ill patients after major surgery. The correlation between P(v-a)CO values and other conventional parameters of patient prognosis was also evaluated.

Usefulness of phase angle on bioelectrical impedance analysis as a surveillance tool for postoperative infection in critically ill patients.

Purpose: Bioelectrical impedance analysis (BIA) has advantages of obtaining results quickly, safely, reproducibly, and non-invasively. Phase angle (PhA) is one of the parameter of BIA, its values represent the permeability or integrity of cell membrane. With the exception of C-reactive protein (CRP), few studies have estimated an association between PhA and these conventional biomarkers.

Clinical importance and characteristics of secondary culture-negative sepsis after surgery for abdominal infection: A retrospective study.

Purpose: Herein, we identified whether the clinical outcomes differ according to secondary culture results in postoperative sepsis patients and determined the predictors of culture-negative sepsis after abdominal surgery based on the secondary culture results.

Methods: Patients who admitted to the intensive care unit(ICU) after surgery due to abdominal infection and diagnosed with postoperative sepsis were included. Culture tests were obtained from body fluids and drains.

Single incision laparoscopic totally extraperitoneal hernioplasty: lessons learned from 1,231 procedures.

Purpose: Although there are many articles about single incision laparoscopic (SIL) hernioplasty, a large-scale study or article about its long-term outcome has not been reported yet. The aim of this study is to assess short- and long-term outcomes of SIL totally extraperitoneal (TEP) hernia repair with large number of cases.

Methods: A prospectively collected database containing details of 1,231 procedures in 1,129 consecutive patients who underwent SIL-TEP hernia repair between June 2010 and December 2017 at a single institution was retrospectively analyzed.

Laparoscopic complete mesocolic excision with D3 lymph node dissection for right colon cancer in elderly patients.

Complete mesocolic excision (CME) with D3 lymph node dissection is considered an oncological surgery for right colon cancer. However, there is still controversy for extensive oncological surgery in elderly patients. The aim of this study is to evaluate the safety and oncological outcomes of laparoscopic CME with D3 lymph node dissection for right colon cancer in elderly patients.

Single-incision laparoscopic appendectomy is a safe procedure for beginners to perform: experience from 1948 cases.

Background: Single-incision laparoscopic appendectomy (SIL-A) has recently become an option for treating appendicitis. The aim of this study was to evaluate the safety, feasibility, and surgical outcomes of SIL-A by residents and surgeons during the learning period.

Methods: A total of 1948 consecutive patients who underwent SIL-A from May 2008 to November 2014 were studied retrospectively.

Single-incision laparoscopic ileostomy is a safe and feasible method of fecal diversion for anastomotic leakage following laparoscopic low anterior resection.

Purpose: Currently, many operations are performed using the single-incision laparoscopic method. Although there have been recent reports on single-incision laparoscopic ileostomy, none have compared this method to conventional laparoscopic ileostomy. This study aimed to assess the safety and feasibility of single-incision laparoscopic ileostomy for anastomotic leakage following laparoscopic low anterior resections.

Feasibility of single-incision laparoscopic appendectomy in a small hospital.

Purpose: This study aimed to compare clinical outcomes for single-incision laparoscopic appendectomy (SILA) and conventional laparoscopic appendectomy (CLA) for the treatment of acute appendicitis and to assess the feasibility of performing SILA in a small hospital with limited surgical instruments and staff experience.

Methods: Retrospective record review identified 133 patients who underwent laparoscopic appendectomy from December 2013 to April 2015. Patients were categorized according to the type of appendectomy performed (SILA or CLA).
