Abstract
Accurate and timely diagnosis of appendicitis in children can be challenging, which leads to delayed admittance or misdiagnosis that may cause perforation. Surgical management involves the elimination of the focus (appendectomy) and the reduction of the contamination with peritoneal irrigation to prevent sepsis. However, the validity of conventional irrigation methods is being debated, and novel methods are needed. In the present study, the use of cold plasma treated saline solution as an intraperitoneal irrigation solution for the management of acute peritonitis was investigated. Chemical and in vitro microbiological assessments of the plasma-treated solution were performed to determine the appropriate plasma treatment time to be used in in-vivo experiments. To induce acute peritonitis in rats, the cecal ligation and perforation (CLP) model was used. Sixty rats were divided into six groups, namely, sham operation, plasma irrigation, CLP, dry cleaning after CLP, saline irrigation after CLP, and plasma-treated saline irrigation after CLP group. The total antioxidant and oxidant status, oxidative stress index, microbiological, and pathological evaluations were performed. Findings indicated that plasma-treated saline contains reactive species, and irrigation with plasma-treated saline can effectively inactivate intraperitoneal contamination and prevent sepsis with no short-term local and/or systemic toxicity.

Abstract
Introduction Inflammatory and protein mediators (cytokine, chemokine, acute phase proteins) play an important, but still not completely understood, role in the morbidity and mortality of intra-abdominal sepsis/injury. We therefore systematically reviewed preclinical and clinical studies of mediators in intra-abdominal sepsis/injury in order to evaluate their ability to: (1) function as diagnostic/prognostic biomarkers; (2) serve as therapeutic targets; and (3) illuminate the pathogenesis mechanisms of sepsis or injury-related organ dysfunction. Methods We searched MEDLINE, PubMed, EMBASE and the Cochrane Library. Two investigators independently reviewed all identified abstracts and selected articles for full-text review. We included original studies assessing mediators in intra-abdominal sepsis/injury. Results Among 2437 citations, we selected 182 studies in the scoping review, including 79 preclinical and 103 clinical studies. Serum procalcitonin and C-reactive protein appear to be useful to rule out infection or monitor therapy; however, the diagnostic and prognostic value of mediators for complications/outcomes of sepsis or injury remains to be established. Peritoneal mediator levels are substantially higher than systemic levels after intra-abdominal infection/trauma. Common limitations of current studies included small sample sizes and lack of uniformity in study design and outcome measures. To date, targeted therapies against mediators remain experimental. Conclusions Whereas preclinical data suggests mediators play a critical role in intra-abdominal sepsis or injury, there is no consensus on the clinical use of mediators in diagnosing or managing intra-abdominal sepsis or injury. Measurement of peritoneal mediators should be further investigated as a more sensitive determinant of intra-abdominal inflammatory response. High-quality clinical trials are needed to better understand the role of inflammatory mediators.

Abstract
BACKGROUND Experimental evidence suggests that laparoscopy could have reduced inflammatory sequelae compared with laparotomy following abdominal surgery for peritonitis. The aim of the present study is to investigate the possible beneficial effects of CO(2) insufflation on liver and lung expression of proinflammatory cytokines during sepsis. METHODS Cecal ligation and puncture (CLP) was induced in Sprague-Dawley rats, and 6 h later rats were randomly subjected to CO(2) pneumoperitoneum (5-7 mmHg) or to laparotomy for 1 h. At the end of the CO(2) pneumoperitoneum or laparotomy procedures, animals were sacrificed, and liver and lung were removed and stored for molecular and histological analysis. RESULTS Liver and lung expression of proinflammatory cytokines was significantly reduced in animals subjected to CO(2) pneumoperitoneum compared with laparotomy. In particular, tumor necrosis factor-alpha (TNF-α) protein expression was significantly reduced (p < 0.05) following CO(2) pneumoperitoneum compared with laparotomy procedures. Interleukin (IL)-6 protein expression was accordingly, markedly reduced (p < 0.05) following CO(2) pneumoperitoneum. Histological analysis showed a reduced inflammatory infiltrate in liver and lung from animals subjected to CO(2) pneumoperitoneum compared with laparotomy. CONCLUSIONS Our results support the hypothesis that laparoscopic procedures reduce the inflammatory cascade, following peritoneal sepsis, via reduced expression of proinflammatory cytokines.

Abstract
Following laparotomy, almost 95% of patients develop adhesions. To prevent adhesion formation, peritoneal lavage has been investigated and many different lavage solutions have been proposed. In this study, different peritoneal lavage solutions were evaluated, testing their ability to prevent adhesion formation. Three consecutive steps were followed: (1) The lethal dose of Eschericia coli injected in the rat peritoneal cavity was determined, (2) the morbidity and mortality rates of different solutions for peritoneal lavage (i.e., saline, twice-distilled water, antiseptics, and antibiotics solutions) was investigated, and (3) the capability of the different lavage solutions to prevent adhesion formation was tested. Two hundred and ninety-eight rats were employed in this study. After intraperitoneal injection of E. coli, infection (clinical signs and animal vitality), adhesion formation (explorative laparoscopy, peritoneumgraphy and Zühlke scale grading), and animal performance status were investigated. All differences were evaluated by chi-square and analysis of variance (ANOVA) tests. Saline solution showed a low morbidity rate with no deaths. Twice-distilled water was associated with 100% mortality rate, as opposed to 45-75% for antiseptics, and 0-3% mortality for antibiotics. Antibiotics determined higher adhesion formation by Zühlke score as compared to saline solution (p < .001), while no difference was observed between antiseptics and saline (p = NS). Peritoneal lavage with 37 degrees C saline solution was associated with low adhesion formation and high survival rate as compared to twice-distilled water and antiseptics. Antibiotics solutions had high survival rate and high adhesion formation. Twice-distilled water and antisepsis should be avoided when based on the data obtained in this work.

Abstract
We hypothesise that reactive oxygen species (ROS) released from activated polymorphonuclear leucocytes during surgery play a crucial role in enhanced tumour recurrence seen after surgery. Therefore, the effect of ROS on adhesion of tumour cells to microvascular endothelium in a reproducible human in vitro model was studied. Preincubation of microvascular endothelial cells with the superoxide anion producing xanthine–xanthine oxidase complex significantly increased adhesion of the human colon carcinoma cells HT29 (167% vs control, P<0.01), Caco2 (164% vs control, P<0.01) and of the pancreas carcinoma cells PanC1 (180% vs control, P<0.01). Addition of the antioxidant enzymes superoxide dismutase or catalase significantly decreased tumour cell adhesion (P<0.01). Exposure of endothelial cells to superoxide anions increased the apoptotic rate to 7.9 times the normal rate. Additionally, exposure increased expression of the endothelial adhesion molecules E-Selectin, ICAM-1, and VCAM-1 of maximally 170% vs control (P<0.01). In conclusion, this study shows that superoxide anions promote the adherence of tumour cells to the microvasculature by inducing endothelial apoptosis that subsequently induces the expression of various adhesion molecules for tumour cells. This indicates that by tackling the production of ROS preventing tumour recurrence at distant sites might be feasible.

Abstract
BACKGROUND Infection of pancreatic necrosis (IPN) is strongly associated with sepsis and multiple organ dysfunction and is an absolute indication for surgery. Patients with IPN are critically ill at the time of surgery and may benefit from a minimally invasive approach with reduced surgical trauma. Recently, several minimally invasive necrosectomy techniques have been reported. However, the effects and potential dangers of a pneumoperitoneum in IPN cases are unknown. This study aimed to determine the effects of a pneumoperitoneum on systemic cytokine levels, bacterial translocation, and systemic organ complications in a rat model of IPN. METHODS For this study, IPN was induced in Wistar rats using retrograde intraductal infusion of 3% taurocholate. After 8 h, the animals were subjected to either laparoscopy (pneumoperitoneum at 8 mmHg) or laparotomy for 1 h and killed after 1 or 3 h. Severe acute pancreatitis with IPN was proved by serum amylase and lipase, histology, tissue activity of myeloperoxidase (MPO), and bacteriology. Systemic levels for interleukin-10 (IL-10), IL-6, tumor necrosis factor-alpha (TNF-alpha), and lipopolysaccarides were determined by enzyme-linked immunoassay (ELISA). Systemic organ damage and dysfunction were evaluated using MPO activity (lung), serum creatinine (kidney), and serum aminotransferases (liver). RESULTS Necrotizing pancreatitis developed in all the animals. Most of the animals (85%) had proven infected necrosis. Elevated cytokine levels and deteriorated organ parameters demonstrated systemic inflammation and organ failure. Although there was a tendency toward a higher level of proinflammatory cytokines after laparotomy, there were no significant differences between laparotomy and laparoscopy. Furthermore, these alterations were not accompanied by any differences in bacterial translocation (lipopolysaccharides), systemic organ damage, or mortality between laparoscopy and laparotomy. CONCLUSION In the current model of infected pancreatic necrosis, a pneumoperitoneum did not result in increased cytokine release or bacterial translocation. However, the putative advantage of less surgical trauma with the laparoscopic approach did not play a significant role in the setting of severe acute pancreatitis with IPN.

Abstract
BACKGROUND The immunologic repercussions due to cavity insufflation are the focus of great discussion. The aim of this study was to compare the inflammatory response and bacterial dissemination after laparotomy and abdominal CO2 insufflation in a murine model of peritonitis. METHODS Swiss mice were inoculated intraperitoneally with 0.5 ml of a solution containing 1 x 10(8) colony-forming units (CFU)/ml of Escherichia coli and were divided into three groups as follow: control (anesthesia for 30 min), laparotomy (2.5-cm midline incision for 30 min), and CO2 pneumoperitoneum (CO2 cavity insufflation for 30 min). The number of leukocytes, CFU/ml counting, and the levels of interleukin (IL)-6, tumor necrosis factor-alpha (TNF-alpha), and IL-10 were evaluated in blood, peritoneal, and pleural fluid samples obtained at 90 min and 18 h after the procedures. RESULTS The laparotomy group showed a greater bacterial dissemination to the blood, peritoneum, and pleural cavity and also greater neutrophil migration to the peritoneal cavity compared to the CO2 insufflated and control groups. The 24-h mortality was also significantly higher in the laparotomy group. The IL-6 levels showed a precocious rise in all groups submitted to bacterial inoculation at the 90-min time point. At the 18-h time point, IL-6 levels in the peritoneum were significantly higher in the laparotomy group than in the control or CO2 insufflated groups. At the same time, TNF-alpha levels were higher in the laparotomy and CO2 insufflated groups than in controls; IL-10 levels showed no differences among the groups. CONCLUSIONS Our results suggest that cavity insufflation with CO2 is a more effective method of access, inducing less bacterial dissemination and also a less intense inflammatory response. Cavity insufflation with CO2 may present a good option for the surgical treatment of patients with bacterial peritonitis.

Abstract
BACKGROUND Laparoscopic techniques have been proposed as an alternative to open surgery for the treatment of peptic ulcer perforation. This study compared the outcome of laparoscopic and open approaches for the repair of gastroduodenal perforations. METHODS A retrospective review was conducted with 134 consecutive patients treated for gastroduodenal perforations. These patients included 122 with perforated duodenal ulcers, 10 with perforated gastric ulcers, and 2 with iatrogenic duodenal perforations. Whereas 68 patients were treated laparoscopically, 66 patients underwent conventional (open) surgery. RESULTS Laparoscopic repair was successful in 65 cases (96 %). The mean operating time was shorter with the laparoscopic technique (68 vs 59 min), but the difference was not significant. The duration of postoperative nasogastric aspiration and time to resumed oral intake were shorter in the laparoscopic group (2.6 vs 4.1 days and 4.4 vs. 5.2 days, respectively; p = 0.043). The postoperative analgetic requirements, and overall complications rate were significantly lower after laparoscopic surgery (p = 0.03 and p = 0.004, respectively). There was no statistically significant difference in hospital stay (5.1 vs 6.1 days) or mortality rate between the two procedures. CONCLUSION Laparoscopic repair of gastroduodenal perforations is a safe alternative treatment offering certain significant short-term advantages.

Abstract
BACKGROUND The purpose of this article is to describe our experience using laparoscopy in the management of emergent and acute abdominal conditions. METHODS Between March 1997 and November 2001, 277 consecutive minimally invasive procedures were performed for various nontrauma surgical emergencies. The indications for operation were nonspecific abdominal pain in 129 cases (46%), peritonitis in 64 cases (23%), small bowel obstruction in 52 cases (19%), complications after previous surgery or invasive procedures in 24 cases (9%), and sepsis of unknown origin in 8 cases (3%). RESULTS Laparoscopy obtained a correct diagnosis in 98.6% of the cases. In 207 patients (75%), the procedure was completed laparoscopically. An additional 35 patients (12.5%) required a target incision. The remaining 35 patients (12.5%) underwent formal laparotomy. The morbidity rate was 5.8%. No laparoscopy-related mortality was observed. CONCLUSIONS For patients with abdominal emergencies, the laparoscopic approach provides diagnostic accuracy and therapeutic options, avoids extensive preoperative studies, averts delays in operative intervention, and appears to reduce morbidity.
