ABSTRACT

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. Materials and methods: From December 2016 to April 2023, patients who underwent emergent surgery due to septic shock secondary to peritonitis and subsequently received blood purification treatment with AN69-oXiris or PMX-HP were enrolled. Propensity score (PS)-matching was conducted to adjust for baseline characteristics between the two groups, and the changes in clinical parameters and outcomes were compared. Clinical outcomes were assessed in subgroups of patients who underwent PMX-HP treatment divided according to SOFA scores into low (0-7), intermediate (8-13), and high (> 13) disease severity groups. Results: Forty patients received blood purification therapy with either PMX-HP or AN69-oXiris during the study period. After 1:2 PS matching, six patients in the AN69-oXiris group and 12 patients in the PMX-HP group were finally analyzed. Vasoactive-inotropic scores (VISs) decreased in both groups after 48 h of treatment compared to the baseline values, but the change in VISs was more pronounced in the PMX-HP group {-57.6 [interquartile range (IQR) = -166.4 - (-10)] vs. -22.9 [IQR = -64-0], respectively, p = 0.041}. Decreases in cardiovascular SOFA scores were significantly pronounced in the PMX-HP group [-1.5 (IQR = -4 - 0) vs. 0 (IQR = -1 - 1), respectively, p = 0.035]. The 7-day mortality rate was significantly lower than the predicted mortality rate in a subgroup analysis of patients treated with PMX-HP in both the low disease severity group and the intermediate disease severity group. Conclusion: PMX-HP and AN69-oXiris could be therapeutic options for refractory septic shock patients with intra-abdominal origins, especially after the surgical elimination of the infectious sources. A tailored modality choice that takes into account patient characteristics, such as disease severity and cost burden, could optimize the efficacy of this strategy.

ABSTRACT

PURPOSE: Change in venous-to-arterial carbon dioxide partial pressure difference[P(v-a)CO2] could be a useful marker to assess tissue perfusion status. Herein, we assessed the predictive values of postoperative P(v-a)CO2 measurements for mortality in critically ill patients after major surgery. The correlation between P(v-a)CO2 values and other conventional parameters of patient prognosis was also evaluated. METHODS: Patients admitted to the intensive care unit(ICU) after abdominal surgery were enrolled. Arterial and venous blood gas analyses were performed within 1 h(T0) and after 24 h(T1) of admission to the ICU, respectively. The relationship between P(v-a)CO2 levels at T1 and other conventional parameters were assessed using a Bland-Altman plot. Logistic regression analysis was performed to examine the predisposing factors of mortality after surgery. RESULTS: A total of 231 patients were finally analyzed. We divided the participants into the high PvaCO2 group[P(v-a)CO2 ≥ 8.6] and the low PvaCO2 group[P(v-a)CO2 < 8.6]. Seven-day-, 28-day, and in-hospital mortality were significantly higher in the high PvaCO2 group than in the low PvaCO2 group. There was significant agreement between P(v-a)CO2 values at T1 and APACHE II scores, lactate levels at T1 and total SOFA scores at T1. In multivariate logistic analysis, an increased P(v-a)CO2 value at T1 was the only significant risk factor of 7-day mortality after surgery. [odds ratio:1.341, 95%confidence interval: 1.050-1.714, p=0.019]. CONCLUSION: P(v-a)CO2 measurements could be not only a significant predictor of postoperative prognosis, but also a useful surveillance parameter to maintain tissue perfusion after abdominal surgery in patients with a potential risk of fatal complication-related tissue hypoperfusion.

ABSTRACT

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. Herein, we aimed to investigate the association between the PhA value and the conventional inflammatory markers in postoperative patients in intensive care unit (ICU). Also, the correlation between the change in PhA and the occurrence of infectious complication were determined. Methods: From July 2020 to February 2022, retrospective observation study conducted in 221 patients who admitted to ICU after abdominal surgery. BIA measurements and blood sampling were routinely performed the next morning. The relationship between PhA and the inflammatory markers were assessed after adjusting for age and body mass index. Univariate and multivariate logistic regression analysis was performed to examine the predisposing factors for postoperative infections. Results: Among 221 patients admitted to ICU after abdominal surgery, infectious complications occurred in 62 cases. CRP, procalcitonin, or presepsin levels were negatively correlated with PhA in both gender. (-0.295, -0.198 or -0.212 of partial correlation coefficients, respectively in males, and 0.313, -0.245 or -0.36 of partial correlation coefficients, respectively in females) But, white blood cell did not show significant association with PhA in both genders. For males, increased level of CRP on postoperative day 1 (POD1) was revealed as the significant predicting factor for postoperative infectious complication [odds ratio (OR): 1.184, 95% confidence interval (CI): 1.090-1.285, p < 0.001]. For females, increased Acute Physiology and Chronic Health Evaluation II score at admission (OR: 1.457, 95% CI: 1.068-1.987, p = 0.018), increased level of presepsin on (OR: 1.003, 95% CI: 1.001-1.006, p = 0.016) and decreased value of PhA on POD1 (OR: 0.980, 95% CI: 0.967-0.993, p = 0.003) were revealed as the significant predicting factors. Conclusion: Phase angle obtained through BIA can be used as a predictor of infection as it shows a significant association with inflammatory markers. Phase angle measurements through BIA could improve patient prognosis after abdominal surgery through the careful observation of infections and early, appropriate treatment.

ABSTRACT

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. Primary culture test was performed immediately after surgery, and secondary culture test was performed within 48 h to 7days after surgery. The participants were divided into the culture-positive sepsis(CPSS) and the culture-negative sepsis group(CNSS) according to culture positivity, and the clinical outcomes were compared. The predisposing factors of secondary CNSS were determined using multiple logistic regression analysis. RESULTS: Among 83 participants, 51 patients (61.4%) showed secondary culture-positivity(2'CPSS) and 32 patients (38.6%) showed secondary culture-negativity(2'CNSS). ICU mortality and in-hospital mortality were not different between two groups, but the length of ICU and hospital stay were significantly longer in 2'CPSS. In multivariate analysis, non-bowel surgery [odds ratio(OR) = 6.934, 95% confidence interval(CI):1.609-29.884, p=0.009], no diabetes (OR = 4.027,95%CI:1.161-13.973, p=0.028), and the prolonged administration of preoperative antibiotics (OR = 1.187,95%CI:1.023-1.377, p=0.024) were revealed as significant predisposing factors of 2'CNSS. CONCLUSION: Mortality showed no difference according to secondary culture positivity in postoperative sepsis patients after abdominal surgery. If a patient underwent non-bowel surgery or had no diabetes or administered preoperative antibiotics for more than 3 days, the physician should pay more attention to clinical deterioration, even if the seconday culture results are negative.

ABSTRACT

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. SIL-TEP hernia repair was performed using a glove single port device and standard laparoscopic instruments. Recurrence rate of SIL-TEP hernia repair was analyzed by a telephone questionnaire. RESULTS: Among 1,129 patients, 1,027 (91.0%) had unilateral hernia and 102 (9.0%) had bilateral hernia. There were 12 (1.1%) conversions to single or 3 ports laparoscopic transabdominal preperitoneal hernioplasty or Lichtenstein repair. Mean operative time was 40.3 minutes for unilateral hernia and 61.6 minutes for bilateral hernia. Intraoperative complication rate was 21.8%. Most intraoperative complications were peritoneum or sac tearing (20.1%). Postoperative complications occurred in 97 (8.6%) cases, most of which were minor morbidity except for 1 mesh infection. Five-year recurrence rate was 4%. CONCLUSION: SIL-TEP hernia repair is safe and technically feasible with acceptable short- and long-term outcomes. Large-scale randomized controlled trials comparing SIL-TEP hernia repair with conventional laparoscopic TEP are needed to confirm these results.

ABSTRACT

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. Surgeries were performed by residents and eight surgeons. Prior to the first case, surgeons and residents had been trained in a training protocol during the learning period. Three initial cases of SIL-A were performed under the supervision of experienced surgeons. Patients were divided into two groups: group 1 (learning period, n = 483), the first 40 cases by each surgeon and resident; and group 2 (experienced period, n = 1465), cases after the 40th procedure performed by each surgeon. Surgical results were compared between the two groups by performing propensity score matching analysis. RESULTS: After propensity score matching, there was no significant difference in patient demographics and characteristics of appendicitis between the two groups. The operating time was longer in group 1 than in group 2 (45.3 ± 18.0 vs. 33.9 ± 16.1 min, p < 0.001). The morbidity rate (7.0% vs. 6.5%, p = 0.795) was similar between the two groups. Readmission rate (2.1% vs. 1.3%, p = 0.414) and reoperation rate (0.8% vs. 0.8%, p = 0.348) were also similar between the two groups. However, the rate of incisional hernia occurrence (0.6% vs. 0%, p = 0.066) tended to be larger in group 1 than in group 2 without showing a significant difference. CONCLUSION: SIL-A is a technically feasible and safe procedure when it is performed by residents and surgeons during learning period under an appropriate training protocol. However, residents and surgeons in the learning period should perform it carefully to prevent incisional hernias.

ABSTRACT

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. Patients who underwent laparoscopic right colectomy, from 2004 to 2014, were divided into Groups A (age ≥ 70 years, n = 80) or B (age < 70 years, n = 127). Short and long-term outcomes were analysed. Basic demographics and short-term surgical outcomes were similar between groups. Among pathological outcomes, the mean number of harvested lymph nodes was significantly less in Group A. Adjuvant chemotherapy refusal rate was significantly higher in Group A. Overall and recurrence-free survival were similar between groups. We found laparoscopic CME with D3 lymph node dissection is a safe and feasible surgical option for right colon cancer in elderly patients.

ABSTRACT

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. METHODS: From April 2012 to April 2017, 38 patients underwent laparoscopic ileostomy (single-incision; 19 patients referred to as group A, conventional laparoscopy; 19 patients referred to as group B) for anastomotic leakage following laparoscopic low anterior resection. We analyzed surgical and clinical outcomes between the 2 groups. Patients in whom a protective ileostomy was carried out during the initial laparoscopic low anterior resection were excluded from this study. RESULTS: No significant differences were observed between the 2 groups in terms of patient demographics and initial operation details. Incisional surgical site infections occurred less in group A than in group B (2 of 19 vs. 9 of 19, P = 0.029). The median ileostomy operation time, amount of intraoperative bleeding, parastomal hernia ratio, hospital stay duration after ileostomy, postoperative pain score were not significantly different between the 2 groups. CONCLUSION: Single-incision laparoscopic ileostomy is safe and feasible method of fecal diversion for anastomotic leakage following laparoscopic low anterior resection.

ABSTRACT

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). Patient characteristics and surgical outcomes were compared between the 2 groups. Postoperative complication rates were compared using the Clavien-Dindo classification. Postoperative pain was assessed using a visual analog scale immediately postsurgery; at 12, 24, 36, and 48 hours postoperatively, and at 7 days postoperatively. RESULTS: Record review identified 38 patients who had undergone SILA and 95 patients who had undergone CLA. No significant differences in clinical characteristics were found between the 2 groups. There were no significant differences in operation time, time to flatus, or length of hospital stay. Overall complication rates were not significantly different between the 2 groups. No complications worse than grade IIIa occurred in the SILA group. Postoperative pain scores were not significantly different between the 2 groups at any time point. CONCLUSION: We found comparable surgical outcomes for SILA compared to CLA. Even in a small hospital with limited surgical instruments and staff experience, SILA may be a feasible and safe technique.
