Objective To study the diagnostic and prognostic value of serum soluble triggering receptor expressed on myeloid cell-1 (sTREM-1) and cyclooxygenase-2 (COX-2) in abdominal infection-caused sepsis. Methods A total of 170 patients with abdominal infection treated in the First Hospital of Qinhuangdao between January 2019 and March 2022 were retrospectively selected and divided into sepsis group (n=76) and non-sepsis group (n=94) according to whether they were combined with abdominal infection-caused sepsis. In addition, 80 healthy people in the same period were selected as the control group. The levels of serum sTREM-1 and COX-2 in the three groups were detected and the differences were compared. The laboratory indexes, including white blood cell count, high-sensitivity C-reactive protein, and procalcitonin of patients with abdominal infection-caused sepsis were detected. The Sequential Organ Failure Assessment score, Acute Physiology and Chronic Health Evaluation System Ⅱ and prognosis (survival or death) of patients with abdominal infection-caused sepsis were evaluated. The correlations of serum sTREM-1 and COX-2 with the severity of sepsis were analyzed, and the diagnostic and prognostic value of sTREM-1 and COX-2 in abdominal infection-caused sepsis was assessed. Results The levels of serum sTREM-1 and COX-2 in the sepsis group were higher than those in the control group and the non-sepsis group (P<0.05). The levels of serum sTREM-1 and COX-2 in the sepsis group were positively correlated with white blood cell count, high-sensitivity C-reactive protein, procalcitonin, Sequential Organ Failure Assessment score, Acute Physiology and Chronic Health Evaluation System Ⅱ score (P<0.05). The serum levels of sTREM-1 and COX-2 of patients who died during hospitalization in the sepsis group were higher than those of the surviving patients. The areas under the receiver operating characteristic curves of the serum sTREM-1 and COX-2 levels for diagnosing sepsis caused by abdominal infection were 0.814 [95% confidence interval (CI) (0.746, 0.882), P<0.001] and 0.848 [95%CI (0.788, 0.905), P<0.001], respectively, with critical values of 1.879 pg/mL and 18.75 ng/mL, respectively, and those for predicting the prognosis of patients with sepsis caused by abdominal infection were 0.775 [95%CI (0.659, 0.890), P<0.001] and 0.784 [95%CI (0.679, 0.889), P<0.001], respectively, with critical values of 2.283 pg/mL and 23.02 ng/mL, respectively (P<0.05). Conclusion The serum levels of sTREM-1 and COX-2 have certain value in the diagnosis and prognosis prediction of abdominal infection-caused sepsis.
Objective To summarize experience and efficacy of multidisciplinary treatment for severe intra-abdominal infection. Methods The clinical data of 17 patients with severe intra-abdominal infection underwent multidisciplinary treatment were analyzed retrospectively. There were 5 cases of severe acute pancreatitis, 4 cases of postoperative biliary fistula, 2 cases of intestinal fistula, 2 cases of pancreatic trauma, 1 case after resection for intestinal necrosis, 1 case of abdominal trauma, 1 case after operation for liver abscess, 1 case of unexplained severe intra-abdominal infection. The experiences of multidisciplinary treatment including the intensive care unit (ICU), surgery, blood purification center, and departments of pharmacy, nutrition, and digestion and internal medicine, and so on were summarized. Results After multidisciplinary treatment, 13 patients were cured, of which 4 patients treated by non-open operation. Three patients died, including 1 patient died of infectious shock, 1 patient died of pancreatic bed bleeding, 1 patient died of multiple organ failure. There was 1 case of automatic discharge. Conclusions Multidisciplinary treatment including ICU, surgery, blood purification center, and departments of pharmacy, nutrition, and digestion and internal medicine, and so on has an exact clinical curative effect in patients with severe intra-abdominal infection. Concept of damage control should be followed by surgical intervention. Abdominal cavity puncture and drainage has some advantages of small trauma and good clinical effect, which is suitable for infection control of patients with severe intra-abdominal infection, it could provide surgical condition and opportunity for patients required further surgical treatment.
To evaluate the development prevention and treatment of pneumonic injury after operation on aged patients with abdominal infection. We analyzed 77 aged patients (＞60 y) admitted from Jan. 1991 to Dec. 1992: 38 cases of which with abdominal infection (infection group), 39 cases without abdominal infection (non-infection group). All patients were given oxygen therapy and continuous SaO2 monitoring. Results: There were 28 patients with hypoxemia (SaO2＜95%) in infection group, with an occurrence rate of 73.7%. In non-infection group (12 patients), the rate of hyoxemia was 30.8%, which has significant difference between two groups (Ｐ＜0.001). All patients with hypoxemia were given oxygen therapy and 31 patients′ SaO2 was elevated. The efficient rate was 77.5%. Other 9 patients developed ARDS, the rate was 2.5% (9/40). In the infection group 8 patients developed ARDS with an occurrence rate of 21.1%. There was one patient with ARDS in the non-infection group, the rate was 2.6%. There was significant difference between two group (Ｐ＜0.05). Conclusions: The results suggest that hypoxemia is liable to occur in aged patients with abdominal infection after operation and these patients were liable to develop ARDS. Oxygen therapy and SaO2 monitoring is the important managements to these patients in prevention of pneumonic injury.
ObjectiveTo explore the clinical efficacy and application significance of continuous irrigation and drainage for intestinal fistula combined with abdominal infection.MethodsClinical data of 62 patients with intestinafistula combined with abdominal infection admitted by Department of General Surgery of The 940th Hospital of The People’s Liberation Army Joint Service Support Force from March 2012 to March 2017 were retrospectively analyzed. All patients were treated with continuous abdominal flushing and drainage after emergency surgery.

To observe the change in plasma endotoxin and cytokine during the early period of intra-abdominal infection (IAI) complicated by multiple system organ dysfunction (MSOD) in animals. Twenty rabbits were randomly divided in to two groups. One group received the operation of cecal ligation plus puncture (CLP) inducing IAI complicated by MSOD, and another group received sham operation as a control. All animals were placed in metabolic cages and maintained with intravenous infusion for one week. Plasma levels of endotoxin and cytokine (TNF, IL-1, IL-6) were determined seperately at the beginning (0 hour) or 1, 2, 3, 4, 5, 6 and 24 hours after CLP. Blood bacteria cultures and pathological examination of several organs were made when the animal was dead or killed. Results: The levels of plasma endotoxin, TNF and IL-6 were found to be significantly increased at one or two hours after CLP, the incidence rate of bacteriemia was 80% and the pathological alterations in the abdomen and organs were remarkale, with an average survival time of 84.1±39.0 hours in CLP group. No change in plasma IL-1 level was found in the CLP group. Conclusion: The plasma levels of endotoxin and cytokine (TNF and IL-6) do increase in the early period of IAI complicated by MSOD, and the change in plasma IL-1 is not obvious.
ObjectiveTo explore the risk factors, pathophysiological mechanism, pathogenic bacteria distribution, diagnosis, and treatment of postoperative intra-abdominal infection, and to provide a theoretical basis for further understanding the mechanism and treatment of postoperative intra-abdominal infection.MethodThe related literatures in PubMed, CNKI, WanFang, and other databases were searched to summarize the research progress of postoperative intra-abdominal infection.ResultsPostoperative intra-abdominal infection was associated with a variety of risk factors, and timely identification and control were conducive to the prevention of intra-abdominal infection. Postoperative intra-abdominal infection had a complex pathophysiological mechanism, mainly involving changes in the immune system, which provided a target for immunotherapy. Pathogenic bacteria were widely distributed in postoperative intra-abdominal infection, and the problem of drug resistance was also a big problem nowadays. In the treatment of postoperative intra-abdominal infection, comprehensive treatment measures should be taken to control the infection, in which the control of the source of infection was the basis and played a key role.ConclusionsThe treatment of postoperative intra-abdominal infection needs to be more individualized and refined, and comprehensive treatment measures such as controlling the source of infection, nutrition therapy, organ function support, and so on, should be taken. Immunotherapy is a new potential treatment measure.
ObjectiveTo review the advances of lymphocinesia in the abdominal cavity infection. MethodsDomestic and foreign literatures about the research of lymphocinesia in the abdominal cavity infection were collected and reviewed. ResultsBacterial translocation occurred when abdominal infection happened. At early phase, bacteria and endotoxin translocation could return and arrive the other tissues or organs through the lymphatic system. The peritoneal lymphatic stomata played an important role in lymphatic circulation, with strong absorption function and immune function. ConclusionsThe theory of lymphatic channels and lymphatic stomata immune pathway is a beneficial supplement to the theory that bacterial and endotoxin can spread to whole body through portal vein pathway, and combination of the 2 kinds of theories can explain the abdominal infection-related systematic infection better. Research of abdominal infection intervention which embarked on the lymphatic pathways would be a promising field.
