Zou WW, Mok HP, Zhu QK, Luo J, Yang S, Cen JZ, Gao Q. Perioperative corticosteroids for reducing postoperative complications following esophagectomy: an updated systematic review and meta-analysis. BMC Surg 2024; 24:57. [PMID: 38360649 PMCID: PMC10870429 DOI: 10.1186/s12893-024-02342-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 02/01/2024] [Indexed: 02/17/2024] Open
Abstract
BACKGROUND This updated systematic review and meta-analysis aims to evaluate the efficacy and safety of perioperative corticosteroid administration versus placebo for esophageal cancer patients following scheduled esophagectomy. METHODS We searched databases through June 30, 2023. We included articles on randomized controlled trials (RCTs) comparing perioperative corticosteroid administration with placebo in esophageal cancer patients with esophagectomy. The outcomes were the death rate during hospitalization, length of hospital stay, and short-term complications. Risk ratios (RRs) and corresponding 95% confidence interval (CIs) for each estimated effect size were applied for dichotomous outcomes, and the mean difference (MD) and corresponding 95% CIs for each estimated effect size were applied for continuous outcomes. We used GRADE to evaluate the quality of each of the outcome and the level of recommendations. RESULTS Nine RCTs with 508 participants were included in this study. Severe outcomes, including the length of hospital stay, leakage, mortality during the hospitalization period in the corticosteroid group was comparable to that in the control group, but positive effects of corticosteroid administration were observed on the length of intensive care unit stay (MD -3.1, 95% CI - 5.43 to - 0.77), cardiovascular disorders (RR 0.44, 95% CI 0.21-0.94) and other general complications (RR 0.49, 95% CI 0.29-0.85). CONCLUSIONS Peri-operative intravenous corticosteroid administration may reduce cardiovascular disorders, other general complications and the length of ICU stay without carrying severe outcomes. More high quality RCTs are warranted to further investigate the effects of corticosteroids on postoperative mortality and complications for esophageal cancer patients with esophagectomy.

Abstract
Inflammation can be a causative factor for carcinogenesis or can result from a consequence of cancer progression. Moreover, cancer therapeutic interventions can also induce an inflammatory response. Various inflammatory parameters are used to assess the inflammatory status during cancer treatment. It is important to select the most optimal biomarker among these parameters. Additionally, suitable biomarkers must be examined if there are no known parameters. We briefly reviewed the published literature for the use of inflammatory parameters in the treatment of patients with cancer. Most studies on inflammation evaluated the correlation between host characteristics, effect of interventions, and clinical outcomes. Additionally, the levels of C-reactive protein, albumin, lymphocytes, and platelets were the most commonly used laboratory parameters, either independently or in combination with other laboratory parameters and clinical characteristics. Furthermore, the immune parameters are classically examined using flow cytometry, immunohistochemical staining, and enzyme-linked immunosorbent assay techniques. However, gene expression profiling can aid in assessing the overall peri-interventional immune status. The checklists of guidelines, such as STAndards for Reporting of Diagnostic accuracy and REporting recommendations for tumor MARKer prognostic studies should be considered when designing studies to investigate the inflammatory parameters. Finally, the data should be interpreted after adjusting for clinically important variables, such as age and cancer stage.

Abstract
PURPOSE The prognosis of esophageal cancer is dismal, and the 3-year overall survival of cStage III does not reach 50.0%. C-reactive protein (CRP) is a well-known protein that reflects the short- and long-term operative outcomes of esophageal cancer. However, since elevated CRP levels are often observed in cStage III esophageal cancer, whether or not CRP still reflects the prognosis is unclear. METHODS Eighty-four patients who were diagnosed with cStage III esophageal cancer and underwent R0/1 operation from January 2007 to December 2014 were retrospectively evaluated. RESULTS The mean age was 66.8 years, and the majority of patients were male. The median preoperative and postoperative CRP levels were 0.15 and 1.47 mg/dl, respectively. A majority of the patients underwent thoracoscopic surgery, and the median blood loss and operation duration were 456 ml and 11.6 h, respectively. Forty-six patients (54.8%) died during the observation period, and the 3-year overall survival was 52.4%. A multivariate analysis showed that the preoperative CRP level, postoperative albumin level, blood loss, and complications were independent prognostic factors. A multiple linear regression analysis showed that an elevated postoperative CRP level was affected by the operation duration and preoperative CRP levels. CONCLUSIONS These findings suggest that the preoperative CRP level is a prognostic factor for cStage III esophageal cancer and that postoperative elevation in the CRP level is affected by the operation duration.

Abstract
OBJECTIVE A prospective randomized phase II trial was conducted to evaluate the efficacy of ghrelin administration in reducing systemic inflammatory response syndrome (SIRS) duration after esophagectomy. BACKGROUND Esophagectomy for esophageal cancer is highly invasive and leads to prolonged SIRS duration and postoperative complications. Ghrelin has multiple effects, including anti-inflammatory effects. METHODS Forty patients undergoing esophagectomy were randomly assigned to either the ghrelin group (n = 20), which received continuous infusion of ghrelin (0.5 μg/kg/h) for 5 days, or the placebo group (n = 20), which received pure saline for 5 days. The primary endpoint was SIRS duration. The secondary endpoints were the incidence of postoperative complications, time of a negative nitrogen balance, changes in body weight and composition, and levels of inflammatory markers, including C-reactive protein (CRP) and interleukin-6 (IL-6). RESULTS The ghrelin group had a shorter SIRS duration and lower CRP and IL-6 levels than did the placebo group. The incidence of pulmonary complications was lower in the ghrelin group than in the placebo group, whereas other complications did not differ between the groups. Although time of the negative nitrogen balance was shorter in the ghrelin group than in the placebo group, changes in total body weight and lean body weight did not differ significantly. CONCLUSIONS Postoperative ghrelin administration was effective for inhibiting inflammatory mediators and improving the postoperative clinical course of patients with esophageal cancer.

Abstract
BACKGROUND We retrospectively evaluated the relationship between cytokine gene polymorphisms and development of postoperative pneumonia after esophagectomy. METHODS In 120 patients who underwent esophagectomy, serum samples were obtained to measure levels of serum interleukin (IL)-6 and IL-10 at four time points (preoperatively, postoperative day (POD)0, POD1, and POD3). DNA extracted from peripheral blood in all patients was analyzed to determine polymorphisms of cytokines such as tumor necrosis factor-α -1031 T/C, IL-1β -511C/T, IL-6 -634C/G, and IL-10 -819 T/C. RESULTS Postoperative pneumonia arose in 34 patients (28.3 %). Perioperative serum IL-10 levels were significantly higher for IL-10 -819 C/T + C/C genotypes than for T/T genotypes (POD0 16.7 ± 2.84 vs. 8.54 ± 0.87 pg/ml, p = 0.0002; POD1 14.0 ± 2.64 vs. 8.8 ± 0.87 pg/ml, p = 0.0143; POD3 8.9 ± 2.67 vs. 4.4 ± 0.52 pg/ml, p = 0.0076). The frequency of the IL-10 -819 T/T genotype was significantly higher in patients with postoperative pneumonia than in patients without pneumonia (p = 0.0323). Multivariate analysis of factors such as sex, smoking, length of operation, field of lymph node dissection, and IL-10 polymorphism identified IL-10 polymorphism as independent predictor of postoperative pneumonia. CONCLUSIONS Patients with IL-10 -819 T/T genotype may be at high risk for postoperative pneumonia after esophagectomy.

Abstract
Background To evaluate the potential efficacy of preventive effect of ulinastatin in esophagectomy patients. Methods Eighty patients with esophageal cancer were preoperatively allocated at random into two equal groups. Ulinastatin was administered to the treatment group (U) whereas the control group (C) received a placebo. The arterial oxygen tension and carbon dioxide tension were measured and the respiratory index (RI) was calculated. Plasma levels of circulating T lymphocyte subsets and interleukin 6 (IL-6) were measured and clinical courses of patients in the two groups were compared. Results RI in the U group was significantly lower than that in the C group. The rate of postoperative complications and the duration of ICU stay were significantly lower in the U group. Ulinastatin significantly increased the rate of CD3+ and CD4+ cells, and ratio of CD4+/CD8+, but decreased the rate of CD8+ cells and release of IL-6 compared to the C group on postoperative days 1 and 3. Patients within the C group showed worse recurrence free survival. Multivariate analysis revealed that ulinastatin administration significantly decreased the incidence of recurrence. Conclusions Ulinastatin had a preventive effect on postoperative complications and immunosuppression in esophagectomy patients, thereby prolongingrecurrence free survival.

Abstract
OBJECTIVE Pulmonary complications after esophagectomy continue to be a significant cause of morbidity and mortality. Although several factors have been implicated to be associated with pulmonary complications after esophagectomy, the prediction of pulmonary complications remains a challenge. The purpose of this study was to evaluate the predictive value of cytokine levels in sera and pleural drainage fluid for pneumonia and hypo-oxygenations following esophagectomy. METHODS A total of 66 patients who underwent esophagectomy for esophageal cancer were retrospectively evaluated for preoperative status, surgical procedures, and postoperative systemic response and laboratory data up to postoperative day (POD) 7. Interleukin-6 (IL-6) and IL-8 levels were also examined in patient sera and pleural drainage fluid until POD 5. RESULTS Eighteen patients (27.3%) had pneumonia following esophagectomy. Patients with pneumonia had significantly more frequent intraoperative blood transfusions, more frequent re-intubation, longer hospital stays, and higher hospital mortality than those without pulmonary complications. Patients with pneumonia had significantly higher levels of serum and pleural IL-6 immediately after surgery and on POD 1 than those without pneumonia. Univariate and multivariate analyses revealed higher pleural IL-6 levels were associated with postoperative minimum PaO2/FiO2 ratio. CONCLUSIONS The elevation of pleural IL-6 levels immediately after surgery and on POD 1 may predict the incidence of pneumonia and the levels of postoperative impaired oxygenation following esophagectomy.

Abstract
BACKGROUND The efficacy of sivelestat in the treatment of acute lung injury/acute respiratory distress syndrome (ALI/ARDS) has not been established. In part, this is due to the wide variety of factors involved in the etiology of ALI/ARDS. In this study, we examined the efficacy of sivelestat in patients with ALI/ARDS associated with abdominal sepsis. METHODS The subjects were 49 patients with ALI/ARDS after surgery for abdominal sepsis. The efficacy of sivelestat was retrospectively assessed in two treatment groups, ie, a sivelestat group (n = 34) and a non-sivelestat group (n = 15). RESULTS The sivelestat group showed significant improvements in oxygenation, thrombocytopenia, and multiple organ dysfunction score. The number of ventilator days (6.6 ± 6.1 versus 11.1 ± 8.4 days; P = 0.034) and length of stay in the intensive care unit (8.5 ± 6.2 versus 13.3 ± 9.5 days; P = 0.036) were significantly lower in the sivelestat group. The hospital mortality rate decreased by half in the sivelestat group, but was not significantly different between the two groups. CONCLUSION Administration of sivelestat to patients with ALI/ARDS following surgery for abdominal sepsis resulted in early improvements of oxygenation and multiple organ dysfunction score, early ventilator weaning, and early discharge from the intensive care unit.

Abstract
The urinary trypsin inhibitor (UTI) is responsible for most of the antitryptic activity in urine and is excreted in increased amounts in urine under certain pathological conditions such as cancer and bacterial infections. Our aim in this study was to better understand the mechanisms responsible for the increase in UTI excretion on surgical stress and thus to better appreciate the information provided by inflammatory mediators. Thirty-one consecutive patients who underwent radical esophagectomy for esophageal cancer were investigated in this study. We determined serum UTI and polymorphonuclear cell elastase (PMNE), urine UTI and evaluated the effectiveness of preoperative administration of methylprednisolone on the postoperative clinical course and adverse inflammatory reactions. The results revealed that urine UTI and serum PMNE levels in the steroid group were significantly lower than those in the non-steroid group. In addition, UTI levels correlated positively with serum levels of aminotransferases. More importantly, the maximum level of urine UTI in patients without complications was lower than that in patients with complications. These results suggest that urine UTI provides useful information concerning postoperative clinical course, and that preoperative administration of methylprednisolone may contribute to decrease postoperative complications following esophagectomy.

Abstract
PURPOSE The goal of this retrospective study was to evaluate the effects of perioperative administration of sivelestat sodium hydrate, a selective neutrophil elastase inhibitor, on the clinical course after radical surgery for esophageal cancer. METHODS The effects of sivelestat on postoperative systemic inflammatory reactions and respiratory function were examined in 53 patients who underwent radical surgery for esophageal cancer between April 2004 and March 2005 with (n = 26, sivelestat group) and without (n = 27, control group) the administration of sivelestat. RESULTS The average age in the sivelestat group was higher than that in the control group, but there were no other differences in the background factors between the two groups. The postoperative oxygenation (PaO(2)/FiO(2) ratio) did not differ between the groups, but the decrease in oxygen saturation (SpO(2)) was significantly inhibited in the sivelestat group compared with the control group (p < 0.01). A significant inhibition of the increase in the CRP level also occurred in the sivelestat group (p < 0.01). The patients in the sivelestat group were also hospitalized for shorter periods compared to those in the control group. CONCLUSION The early administration of sivelestat to patients receiving radical surgery for esophageal cancer can inhibit postoperative systemic inflammatory reactions and it might also have a beneficial effect on the prognosis.

Abstract
The objective of the study was to evaluate the efficacy of sivelestat, a selective neutrophil elastase inhibitor, on body fluid balance after transthoracic esophagectomy. Esophagectomy with elective lymphadenectomy may induce excessive release of neutrophil elastase, which then promotes vascular permeability and an excessive water shift from the intravascular space to the peripheral compartment. Body fluid imbalance after esophagectomy often leads to circular instability, a decrease of urine output, and a delay in the shift to a diuretic state. The study was designed as a case-control study with a historical control group. A retrospective analysis was performed to examine our hypothesis that sivelestat improves abnormal body fluid retention and prevents subsequent pulmonary complications. To reveal the direct influence of sivelestat on the postoperative course, we avoided using steroids or other diuretic agents. Eighty-eight patients who underwent thoracic esophagectomy with extended lymphadenectomy from 2000 to 2008 were divided into two groups: those treated from 2003 to 2008, who all received postoperative administration of sivelestat (n=60); and those treated from 2000 to 2002, who did not receive sivelestat and were used as the control group (n=28). Both groups received fluid management using the same protocol. The time to reach a diuretic state, time until extubation of the tracheal tube, and development of delayed respiratory dysfunction were compared between the groups using univariate and multivariate analysis. The time until a shift to a diuretic state was significantly shorter after treatment with sivelestat (p<0.0001) and with a shorter operation time (p<0.0001). The tracheal tube was extubated significantly earlier in the sivelestat group (p<0.0001) and the incidence of delayed respiratory dysfunction was also significantly lower (p=0.0028) in this group. Multivariate logistic regression analysis showed that a delay in a shift to a diuretic state was a strong independent risk factor for the time to tracheal extubation (odds ratio 2.539, p=0.0056) and occurrence of delayed respiratory dysfunction (odds ratio 1.989, p=0.0104). Sivelestat treatment was not independently associated with reduced pulmonary complications, but the diuretic state was strongly regulated by sivelestat treatment (odds ratio 0.044, p=0.0003). Thus, administration of sivelestat has a beneficial influence on recovery from body water imbalance through a more rapid return to a diuretic state after esophagectomy, which contributes to prevention of subsequent pulmonary complications.

Abstract
Sivelestat sodium hydrate (Ono Pharmaceutical Co., Osaka, Japan) is a selective inhibitor of neutrophil elastase (NE) and is effective in reducing acute lung injury associated with systemic inflammatory response syndrome (SIRS). We conducted a prospective randomized controlled study to investigate the efficacy of perioperative administration of sivelestat sodium hydrate to prevent postoperative acute lung injury in patients undergoing thoracoscopic esophagectomy and radical lymphadenectomy. Twenty-two patients with thoracic esophageal cancer underwent video-assisted thoracoscopic esophagectomy with extended lymph node dissection in our institution between April 2007 and November 2008. Using a double-blinded method, these patients were randomly assigned to one of two groups preoperatively. The active treatment group received sivelestat sodium hydrate intravenously for 72 hours starting at the beginning of surgery (sivelestat-treated group; n= 11), while the other group received saline (control group; n= 11). All patients were given methylprednisolone immediately before surgery. Postoperative clinical course was compared between the two groups. Two patients (one in each group) were discontinued from the study during the postoperative period because of surgery-related complications. Of the remaining 20 patients, 2 patients who developed pneumonia within a week after surgery were excluded from some laboratory analyses, so data from 18 patients (9 patients in each group) were analyzed based on the arterial oxygen pressure/fraction of inspired oxygen ratio, white blood cell count, serum C-reactive protein level, plasma cytokine levels, plasma NE level, and markers of alveolar type II epithelial cells. In the current study, the incidence of postoperative morbidity did not differ between the two groups. The median duration of SIRS in the sivelestat-treated group was significantly shorter than that in the control group: 17 (range 9-36) hours versus 49 (15-60) hours, respectively (P= 0.009). Concerning the parameters used for the diagnosis of SIRS, the median heart rates on postoperative day (POD) 2 were significantly lower in the sivelestat-treated group than in the control group (P= 0.007). The median arterial oxygen pressure/fraction of inspired oxygen ratio of the sivelestat-treated group were significantly higher than those of the control group on POD 1 and POD 7 (POD 1: 372.0 [range 284.0-475.0] vs 322.5 [243.5-380.0], respectively, P= 0.040; POD 7: 377.2 [339.5-430.0] vs 357.6 [240.0-392.8], P= 0.031). Postoperative white blood cell counts, serum C-reactive protein levels, plasma interleukin-1beta, tumor necrosis factor-alpha levels, and plasma NE levels did not differ significantly between the two groups at any point during the postoperative course, nor did serum Krebs von den Lungen 6, surfactant protein-A, or surfactant protein-D levels, which were used as markers of alveolar type II epithelial cells to evaluate the severity of lung injury. Plasma interleukin-8 levels were significantly lower in the sivelestat-treated group than in the control group on POD 3 (P= 0.040). In conclusion, perioperative administration of sivelestat sodium hydrate (starting at the beginning of surgery) mitigated postoperative hypoxia, partially suppressed postoperative hypercytokinemia, shortened the duration of SIRS, and stabilized postoperative circulatory status after thoracoscopic esophagectomy.

Abstract
The inflammatory reactions and tissue response after oesophagectomy are leading causes of postoperative morbidity and mortality. We evaluated the effects of intraoperative infusion of prostaglandin E1 (PGE1) on interleukin-6 (IL-6) levels, (A-a) DO2, pulmonary function and complications. This randomised double-blind clinical trial study was performed on patients undergoing transthoracic oesophagectomy due to cancer. Thirty patients were randomly allocated to two groups: the PGE1 group (infusion of PGE1, 20 ng.kg−1.min−1) and a placebo group (infusion of normal saline 0.9%). The infusion was started before induction of anaesthesia and continued until the end of the operation. The groups were comparable in basic characteristics and preoperative pulmonary function. Patients in the PGE1 group were discharged significantly earlier from the intensive care unit (72±9 vs 83±17 hours) and hospital (13±4 vs 18±8 days) (P=0.04 and 0.03, respectively). The (A-a) DO2 was significantly less in the PGE1 group at 12 and 24 hours after the operation (P=0.001, P=0.003, respectively). Postoperatively, IL-6 levels were significantly higher in the placebo group than in the PGE1 group. There were no differences in the forced expiratory volume in the first second or forced vital capacity. The findings indicate that infusion of PGE1 attenuates the increase in serum levels of IL-6 in patients undergoing esophagectomy and improves the (A-a) DO2. Stays in the intensive care unit and hospital were shorter in the PGE1 group. However, there were no differences in pulmonary complications.

Abstract
PURPOSE Patient-controlled epidural analgesia (PCEA) was developed for use after surgery for thoracic esophageal cancer to relieve wound pain, introduce early rehabilitation, and provide an uneventful postoperative recovery. METHODS This retrospective study investigated 22 patients who underwent esophageal surgery to determine the efficacy of postoperative management with PCEA. In the PCEA group (n = 12), patients had two epidural catheters inserted to cover both the thoracic and abdominal incision with a patient-controlled bolus capability. RESULTS Postoperative mechanical ventilation was administered in all cases in the control group (n = 10). On the other hand, this was only necessary in two patients in the PCEA group. The amount of time the patients stayed in the intensive care unit and the hospital was significantly shorter in the PCEA group than in the control group (P < 0.001 and P < 0.01, respectively). Respiratory complications occurred in four patients in the control group, and none in the PCEA group. The mean number of supplemental analgesics administered for breakthrough pain until the 7th postoperative day was 5.5 in the control group, and 1.3 in the PCEA group (P < 0.001). CONCLUSIONS Early rehabilitation is facilitated with intensive PCEA, while it also improves postoperative management and reduces hospitalization after esophageal surgery.

Abstract
The purpose of this study was to evaluate the effect of sivelestat sodium hydrate, a selective inhibitor of neutrophil elastase in the systemic inflammatory response, pulmonary function, and the postoperative clinical course following esophagectomy. Patients with hypoxia associated with surgical stress in the intensive care unit (ICU) immediately after an esophagectomy were eligible for this study. The degree of hypoxia was calculated according to the ratio of arterial oxygen tension (PaO(2)) to the fractional concentration of inspired oxygen (FiO(2))-PaO(2)/FiO(2). Patients with PaO(2)/FiO(2) < 300 mmHg were enrolled in this study. Seven patients were treated with sivelestat, and 10 were not so treated. The degree of hypoxia, the criteria for systemic inflammatory response syndrome (SIRS), and the postoperative clinical course were compared between the two groups. The postoperative decreases in the PaO(2)/FiO(2) ratio were significantly suppressed in the sivelestat group (p < 0.05, by analysis of variance, or ANOVA). Furthermore, 9 of the 10 control group patients developed SIRS on postoperative day 2, whereas only 2 of 7 of the sivelestat group patients developed SIRS (p < 0.05). The postoperative increases in the heart rate were significantly suppressed in the sivelestat group (p < 0.05, ANOVA). The postoperative decreases in the platelet counts were significantly suppressed in the sivelestat group (p < 0.05, ANOVA). The duration of mechanical ventilation and the length of ICU stay for the sivelestat group were shorter than that for the control group. We demonstrated that the postoperative decreases in the PaO(2)/FiO(2) ratio following esophagectomy were significantly suppressed in the sivelestat-treated group. This clinical study showed that a neutrophil elastase inhibitor may thus be a potentially useful drug for treating acute lung injury following esophagectomy.

Abstract
Sivelestat sodium hydrate is a selective inhibitor of neutrophil elastase (NE), and is effective in acute lung injury associated with systemic inflammatory response syndrome (SIRS). The effect of Sivelestat for postoperative clinical courses after transthoracic esophagectomy was investigated. Consecutive patients with carcinoma of the thoracic esophagus who underwent transthoracic esophagectomy between 2003 and 2004 were assigned to the Sivelestat-treated group (n = 18), and those between 1998 and 2003 were assigned to the control group (n = 25). The morbidity rate, duration of postoperative SIRS, mechanical ventilation, and intensive care unit (ICU) stay, and the sum of the sequential organ failure assessment scores at all time points after the operation were compared. Serum NE activities and serum concentrations of TNF-alpha, IL-1beta, IL-6, and high mobility group box chromosomal protein 1 (HMGB1) were measured. Postoperative complications developed in three patients in the control group, and one in the Sivelestat-treated group. The durations of SIRS, mechanical ventilation, and ICU stay were significantly shorter in the Sivelestat-treated group. Even in patients without complications, the durations of mechanical ventilation, and ICU stay were also significantly shorter, and the arterial oxygen pressure/fraction of inspired oxygen ratio at postoperative day 1 was significantly higher in the Sivelestat-treated group. Serum NE activities and serum concentrations of IL-1beta, IL-6, and HMGB1 were significantly suppressed in the Sivelestat-treated group. Postoperative Sivelestat treatment after transthoracic esophagectomy improves the condition of SIRS and postoperative clinical courses, even in patients without complications.

Abstract
Gabexate mesilate (GM), a synthetic serine protease inhibitor, suppresses nuclear factor-kappaB (NF-kappaB) activity in human monocytes or human umbilical vein endothelial cells (HUVECs). In this study we examine whether GM also suppresses NF-kappaB activation and induces apoptosis in human pancreatic cancer cell lines. The addition of tumor necrosis factor alpha (TNF-alpha) did not change the rates of growth of BxPC-3 and MIA PaCa-2. However, in the presence of GM and TNF-alpha, proliferation decreased in a dose-dependent manner. GM- and TNF-alpha-treated cells exhibited morphologic changes indicative of apoptosis, including chromatin condensation and nuclear fragmentation. The NF-kappaB activity of both cell lines was increased by the addition of TNF-alpha, while TNF-alpha-induced NF-kappaB activity was suppressed by prestimulation with GM in a dose-dependent manner. Caspase 3 and 7 activity was significantly increased by TNF-alpha with GM stimulation. Furthermore, GM also suppressed the invasive potential of both cell lines. These results indicate that GM inhibits TNF-alpha-induced NF-kappaB activation and enhances apoptosis in human pancreatic cancer cell lines.

Abstract
PURPOSE To examine the effects of the administration of perioperative sivelestat, a selective neutrophil elastase inhibitor, on tumor immunity and inflammatory mediators in patients who undergo major surgery. METHODS Thirteen patients admitted to the hospital for elective surgery were equally randomized into one of two groups: the Sivelestat group (n = 6) and the control group (n = 7). Thereafter, the immunosuppressive acidic protein (IAP), serum interleukin-6 (IL-6), and type 1/type 2 T-helper cell balance were all assessed at several time points before and after surgical intervention. RESULTS The serum IL-6 values at 1 and 12 h after surgery and on postoperative days 1 and 3 were all significantly lower in the sivelestat group than in the control group. The IAP values at postoperative days 7 and 28 in the sivelestat group were also significantly lower than those in the control group. There was a significant correlation between the IL-6 level at 1 h after surgery and the IAP level at postoperative days 7 and 28. CONCLUSIONS In this preliminary study, the perioperative administration of sivelestat was thus suggested to reduce surgical stress by decreasing the cytokine release and preserving the antitumor immunity.

Abstract
BACKGROUND High-mobility group box chromosomal protein 1 (HMGB1) has recently been shown to be an important late mediator of endotoxin shock, intraabdominal sepsis, and acute lung injury, and a promising therapeutic target of severe sepsis. We sought to investigate the effect of antibodies to HMGB1 on severe sepsis in a rat cecal ligation and puncture (CLP) model. METHODS Adult male Sprague-Dawley rats underwent CLP and then were randomly divided into two groups: treatment with anti-HMGB1 polyclonal antibodies, and non-immune IgG-treated controls. The serum HMGB1 concentrations were measured at ten time points (preoperatively, and postoperatively at 4, 8, 20, 32, and 48 h and at 3, 4, 5, and 6 days). Hematoxylin-eosin staining, elastica-Masson staining, and immunohistochemical staining for HMGB1 were performed on the cecum and the lung to assess pathological changes 24 h after the CLP procedure. RESULTS Treatment with anti-HMGB1 antibodies significantly increased survival [55% (anti-HMGB1) vs. 9% (controls); P< 0.01]. The serum HMGB1 concentrations at postoperative hours 20 and 32 of the anti-HMGB1 antibody-treated animals were significantly lower than those of the controls (P < 0.05). Treatment with anti-HMGB1 antibodies markedly diminished the pathological changes and the number of HMGB1-positive cells in the cecum and the lung. CONCLUSIONS The present study demonstrates that anti-HMGB1 antibodies are effective in the treatment of severe sepsis in a rat model, thereby supporting the relevance of HMGB1 eradication therapy for severe sepsis.

Abstract
BACKGROUND Chemoradiotherapy (CRT) has been established to improve the long-term survival in patients with esophageal carcinoma. However, little is known about whether preoperative CRT may affect the postoperative systemic response. METHODS We investigated the postoperative clinical course in terms of the systemic inflammatory response syndrome (SIRS) in patients with preoperative CRT (CRT group) and surgery alone (SA group). RESULTS Both the postoperative heart and respiratory rate in the CRT group were significantly higher than in the SA group. The duration and incidence of SIRS, as well as the number of positive criteria for SIRS, were significantly greater than those in the SA group. There was no difference in the postoperative morbidity and mortality between the two groups. CONCLUSIONS Preoperative CRT was found to significantly enhance the postoperative SIRS, thus suggesting its potentially higher risk of complications.

Abstract
BACKGROUND Because surgical stress is thought to have an effect on morbidity, mortality, and remnant tumour progression after surgery, diminishing surgical stress is important. The purpose of this study was to assess in a murine model whether the length and type of laparotomy incision influence surgical stress. METHODS Serum IL-6 concentrations were measured sequentionally in 220 male BALB/c mice who were assigned to different basic laparotomies, (1-cm versus 2-cm versus 3-cm laparotomy with or without caecal resection), other types of laparotomy (3-cm, 1-cm x 3, 3-cm transverse, 3-cm laparotomy with rapid closure), or 3-cm skin incision with or without laparotomy. The serum level of IL-6 was measured by ELISA. RESULTS Serum IL-6 levels at 3 and 6h after surgery were significantly higher in the 3-cm laparotomy group (1,680+/-802pg/ml and 1,066+/-507pg/ml, respectively), than in the 1-cm laparotomy group (797+/-427pg/ml and 515+/-212pg/ml, respectively). When caecal resection was added, the serum IL-6 level at 6h was significantly higher in the 3-cm laparotomy group (2,844+/-134pg/ml) than in the 1-cm laparotomy group (2,200+/-379pg/ml). Although the type of laparotomy incision was not associated with the serum level of IL-6, the serum IL-6 level after midline skin incision without laparotomy (245+/-142pg/ml) was significantly lower than that after 3-cm laparotomy (1,680+/-802pg/ml). CONCLUSIONS The length of laparotomy incision was correlated with the serum level of IL-6 in a murine model. The surgical stress related to abdominal procedures might be decreased when laparotomy wounds are kept as small as possible.

High-mobility group box chromosomal protein 1 (HMGB-1) has recently been shown as an important late mediator of endotoxin shock, intra-abdominal sepsis, and acute lung injury. However, its role in the systemic inflammatory response syndrome after major surgical stress, which may lead to multiple organ dysfunction syndrome, has not been thoroughly investigated. We hypothesized that serum HMGB-1 participates in the pathogenesis of postoperative organ system dysfunction after exposure to major surgical stress. A prospective clinical study was performed to consecutive patients (n = 24) with carcinoma of the thoracic esophagus who underwent transthoracic esophagectomy with three field lymph node resection between 1998 and 2003 at Keio University Hospital, Japan. Serum HMGB-1 concentrations were measured by enzyme-linked immunosorbent assay. Preoperative serum HMGB-1 levels correlated with postoperative duration of SIRS, mechanical ventilation, and intensive care unit stay. Three of the 24 patients had serious postoperative complications: sepsis in two, and acute lung injury in one. Serum HMGB-1 levels in patients without complications increased within the first 24 h postoperatively, remained high during postoperative days 2-3, and then decreased gradually by postoperative day 7. In patients with serious complications, serum HMGB-1 was significantly higher than that found in patients without postoperative complications at every time point except postoperative day 2. Preoperative serum HMGB-1 concentration seems to be an important predictor of the postoperative clinical course. Transthoracic esophagectomy induces an increase in HMGB-1 in serum even in patients without complications. Postoperative serum HMGB-1 concentrations were higher in patients who developed complications, and may be a predictive marker for complications in this setting.

Abstract
BACKGROUND The severity of ischemia and reperfusion (I/R) injury is an important determinant of patient outcome in hepatic surgery. The aim of this study was to investigate the efficacy of a protease inhibitor in alleviating I/R injury to human liver in the setting of hepatectomy under intermittent Pringle maneuver. METHODS Sixty patients who underwent liver resection under conditions of intermittent inflow occlusion were randomly assigned to 2 groups (n = 30 each) according to the use of a synthetic protease inhibitor (gabexate mesilate or GM). GM was administered intravenously at a dosage of 2.0 mg/kg/h starting 12 hours before surgery until postoperative day 2. Preoperative and intraoperative clinical variables and postoperative outcomes were evaluated. The plasma levels of a cytokine, interleukin (IL)-6, as well as laboratory biochemical liver function parameters were analyzed to evaluate hepatic I/R injury. RESULTS The 2 groups of patients were comparable with regard to hepatic inflow occlusion time, extent of liver resection, and background liver histology. The preoperative administration of GM (GM group) substantially alleviated hepatic I/R injury compared with the untreated control group; postoperative serum transaminase levels were significantly decreased in association with marked suppression of IL-6 levels in blood circulation during surgery. This was accompanied by a lower incidence of postoperative complications. The patients without postoperative complications had significantly lower activities of plasma IL-6 at 24 hours after surgery. CONCLUSIONS This prospective randomized study demonstrated the hepatoprotective effect of a synthetic protease inhibitor in the setting of hepatectomy under the intermittent Pringle maneuver.

Abstract
Several drugs that quicken recovery from neuromuscular blockade caused by vecuronium in anesthetized patients are reviewed. Ulinastatin, a protease inhibitor, is thought to promote the release of acetylcholine at the neuromuscular junction and increases hepatic blood flow and urine volume. For this reason, ulinastatin quickens recovery from neuromuscular blockade in anesthetized patients receiving vecuronium. Additionally, pretreatment with ulinastatin avoids prolongation of vecuronium-induced neuromuscular blockade in patients with hepatic cirrhosis. Gabexate mesilate is also a protease inhibitor. During a continuous infusion of gabexate mesilate, recovery from neuromuscular blockade was quickened. Amino acid-enriched solution supplies energy to the skeletal muscles and causes an increase in muscle strength. An infusion of amino acid-enriched solution hastens recovery from neuromuscular blockade in anesthetized patients. When amino acids supply energy to the skeletal muscles, they simultaneously produce heat in the skeletal muscles. This thermal generation may be closely related to fast recovery from neuromuscular blockade. Amino acid-enriched solution makes recovery from neuromuscular blockade quick and avoids hypothermia during general anesthesia. Milrinone, a phosphodiesterase III inhibitor, is supposed to increase the release of acetylcholine at the neuromuscular junction and make the neuromuscular junction sensitive to acetylcholine. Therefore, recovery from neuromuscular blockade is hastened. Nicorandil enhances membrane K+ conductance in skeletal muscle and increases contraction of the skeletal muscle. Thus, nicorandil quickens recovery from neuromuscular blockade.

Abstract
In spite of improvements in surgical technique and perioperative care, severe lung complication remains as the leading cause of morbidity in thoracic esophageal cancer patients who undergo esophagectomy. The purpose of this study was to evaluate the safety and effectiveness of postoperative drug therapy using low dose dopamine, gabexate mesilate, and ulinastatin on postoperative lung complication in esophageal cancer patients. Sixty-one patients operated for esophageal cancer from 1996 to 2000 were treated postoperatively with low dose dopamine (300 microg/kg/h), gabexate mesilate (80 mg/h), and ulinastatin (300 000 unit/day) as a study group. Seventy-four patients operated from 1987 to 1994 served as an historical control group. Various preoperative and perioperative medical parameters and water balance were analyzed. Postoperative pulmonary complications were observed in 26 patients (35.1%) in the control group and three patients (4.9%) in the study group, respectively (P < 0.0001). Preoperative and perioperative variables were not significantly different between the groups. Water balance from operation to postoperative day 3 in the study group was significantly lower than the control group. Postoperative use of low dose dopamine, gabexate mesilate, and ulinastatin significantly reduced pulmonary complications after esophagectomy. This may be partly attributable to negative water balance during the early postoperative days.

Abstract
BACKGROUND Oesophageal surgery causes morbidity and mortality from respiratory complications. We tested the possibility that prostaglandin E1 (PGE1) could reduce inflammatory cytokine responses and improve gas exchange after oesophagectomy. METHODS We randomized 14 patients into two groups. One group received PGE1 20 ng kg(-1) min(-1) i.v. during anaesthesia (PGE1 group) and the other group did not (control group). Anaesthesia was maintained with sevoflurane and epidural anaesthesia. During oesophagectomy, ventilation of one lung was carried out with a double-lumen bronchial tube. The patients were extubated on or after the first postoperative day. Blood samples were taken at induction of anaesthesia, at the end of thoracotomy, at the end of the operation, 2 h after surgery and on the first day after surgery. RESULTS The groups were similar for ASA physical status, age, FEV1%, operation time, duration of thoracotomy, intraoperative fluid volume and blood loss. The arterial blood gas and arterial pressure during surgery were also similar in the PGE1 and control groups. However, the PaO2/FiO2 ratio on the first day after surgery was significantly greater in the PGE1 group compared with the control group. Serum concentrations of IL-6 and IL-8 increased after surgery in both groups. IL-6 was significantly less in the PGE1 group at the end of the operation and 2 h after the operation. CONCLUSIONS Intraoperative PGE1 reduced IL-6 production in patients undergoing oesophagectomy and oxygenation was better in the postoperative period.

Abstract
Proinflammatory cytokines have been implicated in mediating respiratory failure associated with major surgery. We investigated the effect of giving glucocorticoids preoperatively for the prophylaxis of surgical stress and the association of cytokine levels, such as interleukin-6 (IL-6) and interleukin-8 (IL-8), with oxygenation after esophagectomy. We studied 17 patients who underwent subtotal esophagectomy. Seven patients (steroid group) were chosen at random to be given methylprednisolone (10 mg/kg) and 10 patients (control group) to be given saline intravenously before operation. Plasma and bronchoalveolar lavage fluid (BALF) IL-8 levels in the control group were significantly higher than those in the steroid group. In both groups, plasma IL-6 levels were significantly higher than those in BALF, but in contrast, BALF IL-8 levels were significantly higher than plasma levels of IL-8 postoperatively. The PaO(2)/FiO(2) ratio was significantly reduced in the control group. The PaO(2)/FiO(2) ratio of the control group had significantly lower values than that of the steroid group. There was significant correlation between BALF IL-8 levels and the PaO(2)/FiO(2) ratio postoperatively. We conclude that preoperative administration of methylprednisolone may attenuate postoperative reduction of arterial oxygen saturation by suppressing the release of cytokines.

Abstract
BACKGROUND Total clamping of the hepatic pedicle can induce profound hepatic ischemia/reperfusion (I/R) injury, which remains a potentially lethal problem after hepatectomy. STUDY DESIGN The purpose of this study was to evaluate the efficacy of a protease inhibitor in ameliorating I/R injury of the human liver. In a prospective, randomized, clinical study, 66 patients who underwent liver resection under conditions of continuous inflow occlusion were randomly assigned to three groups: 25 patients were given a synthetic protease inhibitor (gabexate mesilate [GM], 2.0 mg/kg/hr) intravenously starting 24 hours before surgery until postoperative day 3 (preop GM group); 16 were similarly given GM at the beginning of surgery (intraop GM group); and 25 served as controls (without GM group). Laboratory data and intraoperative and postoperative variables were analyzed and plasma levels of cytokines--tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta), and interleukin-6 (IL-6)--were measured to determine the relationship between surgical stress and hepatic I/R injury. RESULTS The three groups of patients were similar in terms of age, gender, preoperative assessments, hepatic inflow occlusion time (approximately 50 minutes), extent of resection (proportion of major and minor hepatectomy), and background liver conditions. Preoperative administration of gabexate mesilate (preop GM group) substantially ameliorated hepatic I/R injury as compared with the other patients (intraop and without GM groups); postoperative serum transaminase levels were notably decreased in association with marked suppression of IL-6 levels in blood circulation during liver surgery. This was accompanied by a lower rate of postoperative complications and no mortality. Gabexate mesilate pretreatment abrogated the positive correlation between postreperfusion hepatocyte injury and hepatic ischemia time. CONCLUSIONS Preoperative administration of GM is useful for preventing I/R injury of the human liver, accompanied by suppression of the plasma proinflammatory cytokine IL-6.

Abstract
UNLABELLED Proinflammatory cytokines have been implicated in mediating myocardial dysfunction associated with major surgery. We investigated the profile of proinflammatory cytokines and the association of cytokine levels with myocardial function after esophagectomy. We studied 12 patients who underwent subtotal esophagectomy. One patient died of multiple organ failure. This patient had the largest interleukin-6 (IL-6) level of all the subjects. IL-6 levels increased from 14.9 +/- 8.7 pg/mL to 498.4 +/- 294.3 pg/mL (P < 0.05) at 6 h postoperatively. Interleukin-8 (IL-8) levels also significantly increased postoperatively. Right ventricular ejection fraction (RVEF) decreased from 44% +/- 1% to 36% +/- 2% (P < 0.05) and 37% +/- 2% (P < 0.05) at 6 h and 12 h postoperatively. Stroke volume index (SVI) decreased significantly at the end of operation and at 6 h and 12 h postoperatively. The changes of RVEF and SVI showed an independent negative correlation with the IL-6 level (r = -0.70, P < 0.001 and r = -0.62, P < 0.001, respectively). In contrast, the change of RVEF and SVI was not correlated with the IL-8 level. Esophagectomy is associated with transient depression of myocardial function. IL-6 may contribute to this postoperative myocardial dysfunction. IMPLICATIONS We examined the association between myocardial function and proinflammatory cytokines after esophagectomy. Interleukin-6 may be the cytokine that most sensitively reflects the postoperative myocardial dysfunction.

Abstract
BACKGROUND Surgical stress affects intestinal permeability and our earlier study using a rat model indicated that oxidative stress plays an important role in this process. Proteases are important mediators of cellular damage and are known to be activated in oxidative stress. This study looked at protease activity in enterocytes after surgical stress. METHODS Surgical stress was induced by opening the abdominal wall and handling the intestine as done during laparotomy, in normal and xanthine oxidase-deficient rats. Enterocytes at various stages of differentiation were isolated and protease activity and protection offered by xanthine oxidase inhibitors were determined. Mitochondria and cytosol were prepared from total isolated enterocytes at different periods after surgical stress and protease activation was studied. RESULTS Surgical stress induced activation of proteases in both the villus and crypt cells. Protease activation is seen in both mitochondria and cytosol, and similar to the other alterations in mucosal cells, protease activation was maximum 60 min after stress, returning to normal by 24 h. Thiol compounds modulate protease activity in both mitochondria and cytosol and the activation is not seen in xanthine oxidase-deficient animals. CONCLUSIONS Surgical stress induces activation of proteases in villus and crypt cells of the small intestine. Both mitochondrial and cytosolic proteases are activated and free radicals generated by xanthine oxidase may mediate protease activation after surgical stress in the intestine.
