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 understand the research progress of triggering receptor expressed on myeloid cells-1 (TREM-1) in abdominal infection and sepsis. MethodsThe relevant literatures at home and abroad in recent years regarding the research on the role of TREM-1 in abdominal infection and sepsis were retrieved and reviewed. ResultsRecent studies have focused on the key role of TREM-1 in abdominal infection and sepsis. TREM-1 is a pattern recognition receptor, which rapidly upregulated under inflammatory stimulation, forming a positive feedback loop that significantly amplifies the immune response. Its activation can trigger the cascaded release of a large number of proinflammatory factors and chemokines, exacerbating the inflammatory storm; at the same time, excessive activation of the pathway is regarded as the core driving mechanism for the progression of sepsis and even septic shock. ConclusionsThe TREM-1 mediated amplification effect of inflammatory cascades has been identified as a key link in immune imbalance in infectious diseases such as sepsis and abdominal infection. Further clarification of the expression dynamics of TREM-1 under different infectious conditions and the regulatory mechanisms of its signaling pathways is expected to provide new biomarkers for the clinical diagnosis and prognostic evaluation of infectious diseases, as well as theoretical basis for targeted intervention strategies and new drug development, thereby promoting the establishment and optimization of precise diagnosis and treatment regimens.
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. The duration of peritoneal flushing, antibiotic use, blood picture recovery, fistula healing, and total hospitalization were summarized.ResultsAll 62 patients were treated successfully without death or septic shock. Among them, 49 cases of intestinal fistula were treated with continuous abdominal flushing and drainage, and 13 cases of intestinal fistula were treated by continuous flushing and drainage of the abdominal cavity. There were 6 cases of abdominal abscess, 5 cases of incision infection, 5 cases of pleural effusion, and 2 cases of pulmonary infection after surgery. The continuous abdominal cavity washing time was (45±21) d, antibiotic use time was (14±7) d, blood image recovery time was (16±8) d, the healing time of fistula was (47±24) d, total length of hospital stay was (56±27) d.ConclusionsFor intestinal fistula combined with abdominal cavity infection, peritoneal continuous flushing and drainage is related with curative effect, high cure rate, fewer complications, simple washing equipment, simple technology, lower cost, and convenient nursing, which can create a good condition for the complexity or refractory patients with intestinal fistula, and has a high clinical application significance.
ObjectiveTo evaluate the safety and efficacy of unconventional abdominal drainage after laparoscopic hepatectomy.MethodsThe clinicopathologic data of patients who underwent laparoscopic hepatectomy for liver tumors in the Mianyang Central Hospital from June to December 2019 and met the inclusion criteria were retrospectively collected. Based on whether drainage tube was placed in the abdominal cavity during operation, the patients were divided into non-catheterized group (without drainage tube) and catheterized group (with drainage tube). The intraoperative data and postoperative complications (e.g. intraabdominal hemorrhage, bile leakage, abdominal infection, and liver failure) were compared between the two groups. Then, the intraoperative data and postoperative conditions of liver cancer and non-liver cancer patients with or without abdominal drainage tube were compared and analyzed.ResultsA total of 117 eligible patients were included in the study. The non-catheterized group had 59 patients and the catheterized group had 58 patients. The patients with liver cancer had 84 patients (44 non-catheterized patients and 40 catheterized patients) and the patients without liver cancer had 33 patients (15 non-catheterized patients and 18 catheterized patients). ① On the whole, the groups were comparable in the baseline data between the non-catheterized group and the catheterized group, such as gender, age, HBV infection, body mass index, hepatic function index, liver stiffness value, disease category, etc. (P>0.05). Compared with the catheterized group, the non-catheterized group had earlier off-bed activities and earlier flatus time (P<0.001), and shorter postoperative hospital stay (P=0.030). However, no statistically significant differences were found in other indicators between the two groups (P>0.05). ② Whether the patients had liver cancer or not, the non-catheterized patients still had earlier off-bed activities and earlier flatus time as compared with the catheterized patients (P<0.001). Among the patients with liver cancer, no difference was found in postoperative hospital stay. However, among the patients without liver cancer, the non-catheterized patients had shorter postoperative hospital stay than the catheterized patients (P=0.042). No statistically significant differences were found in other indicators between the catheterized patients and non-catheterized patients (P>0.05).ConclusionFor technologically skilled laparoscopic hepatectomy center, selectively not placing peritoneal drainage tube after surgery might better promote the health of patients.
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.
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.
