Risk Factors For Intra-abdominal Infection Research Articles

Preoperative blood markers and intra-abdominal infection after colorectal cancer resection.

Colorectal cancer (CRC) has one of the highest morbidity and mortality rates among digestive tract tumors. Intra-abdominal infection (IAI) is a common postoperative complication that affects the clinical outcomes of patients with CRC and hinders their rehabilitation process. However, the factors influencing abdominal infection after CRC surgery remain unclear; further, prediction models are rarely used to analyze preoperative laboratory indicators and postoperative complications. To explore the predictive value of preoperative blood markers for IAI after radical resection of CRC. The data of 80 patients who underwent radical resection of CRC in the Anorectal Surgery Department of Suzhou Hospital affiliated with Anhui Medical University were analyzed. These patients were categorized into IAI (n = 15) and non-IAI groups (n = 65) based on whether IAI occurred. Influencing factors were compared; general data and laboratory indices of both groups were identified. The relationship between the indicators was assessed. Further, a nomogram prediction model was developed and evaluated; its utility and clinical applicability were assessed. The risk factors for IAI after radical resection of CRC were neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and carcinoembryonic antigen (CEA) levels. NLR was correlated with PLR and SII (r = 0.604, 0.925, and 0.305, respectively), while PLR was correlated with SII (r = 0.787). The nomogram prediction model demonstrated an area under the curve of 0.968 [95% confidence interval (CI): 0.948-0.988] in the training set (n = 60) and 0.926 (95%CI: 0.906-0.980) in the validation set (n = 20). The average absolute errors of the calibration curves for the training and validation sets were 0.032 and 0.048, respectively, indicating a good model fit. The decision curve analysis curves demonstrated high net income above the 5% threshold, indicating the clinical practicality of the model. The nomogram model constructed using NLR, PLR, SII, and CEA levels had good accuracy and reliability in predicting IAI after radical resection of CRC, potentially aiding clinical treatment decision-making.

Development and validation of a nomogram to predict postsurgical intra-abdominal infection in blunt abdominal trauma patients: A multicenter retrospective study

BackgroundIntra-abdominal infection is a common complication of blunt abdominal trauma. Early detection and intervention can reduce the incidence of intra-abdominal infection and improve patients’ prognoses. This study aims to construct a clinical model predicting postsurgical intra-abdominal infection after blunt abdominal trauma. MethodsThis study is a retrospective analysis of 553 patients with blunt abdominal trauma from the Department of General Surgery of 7 medical centers (2011–2021). A 7:3 ratio was used to assign patients to the derivation and validation cohorts. Patients were divided into 2 groups based on whether intra-abdominal infection occurred after blunt abdominal trauma. Multivariate logistic regression and least absolute shrinkage and selection operator regression were used to select variables to establish a nomogram. The nomogram was evaluated, and the validity of the model was further evaluated by the validation cohort. ResultsA total of 113 were diagnosed with intra-abdominal infection (20.4%). Age, prehospital time, C-reactive protein, injury severity score, operation duration, intestinal injury, neutrophils, and antibiotic use were independent risk factors for intra-abdominal infection in blunt abdominal trauma patients (P < .05). The area under the receiver operating curve (area under the curve) of derivation cohort and validation cohort was 0.852 (95% confidence interval, 0.784–0.912) and 0.814 (95% confidence interval, 0.751–0.902). The P value for the Hosmer-Lemeshow test was .135 and .891 in the 2 cohorts. The calibration curve demonstrated that the nomogram had a high consistency between prediction and practical observation. The decision curve analysis also showed that the nomogram had a better potential for clinical application. To facilitate clinical application, we have developed an online at https://nomogramcgz.shinyapps.io/IAIrisk/. ConclusionThe nomogram is helpful in predicting the risk of postoperative intra-abdominal infection in patients with blunt abdominal trauma and provides guidance for clinical decision-making and treatment.

Clinical Characteristics and Risk Factors for Intra-Abdominal Infection with Chryseobacterium indologenes after Orthotopic Liver Transplantation.

The incidence of hospital-acquired infections caused by Chryseobacterium indologenes (C. indologenes) is increasing. This study investigated the epidemiological and clinical features of C. indologenes intra-abdominal infections in patients who underwent orthotopic liver transplantation (OLT). In this retrospective study, 53 consecutive non-replicate clinical isolates of C. indologenes were collected and identified from the OLT patients at a tertiary care university hospital in Shanghai in 2017. Genetic relatedness of the isolates was determined by enterobacterial repetitive intergenic consensus polymerase chain reaction DNA fingerprinting. Antimicrobial susceptibility of the isolates was measured using the microdilution broth method. Nosocomial clonal transmission of C. indologenes was confirmed by bacterial homology analysis. All C. indologenes isolates were resistant to β-lactams, carbapenems, quinolones, and aminoglycosides, and showed susceptibility to trimethoprim–sulfamethoxazole and minocycline. Multivariate risk modelling revealed that ≥2 bed transfers and an operation time of ≥8 h were independent risk factors for C. indologenes intra-abdominal infection after OLT. A nomogram was constructed based on the screened risk factors, which showed good concordance and accuracy. Clonal dissemination of C. indologenes in OLT patients was demonstrated and several risk factors for intra-abdominal infections were identified. Epidemiological surveillance of this organism and extensive surveillance programs are imperative worldwide.

A novel nomogram based on nutritional and immune status predicting postoperative intra-abdominal infection in colorectal cancer.

This study aimed to investigate independent risk factors for intra-abdominal infection and to construct a nomogram to identify colorectal patients at a high risk of intra-abdominal infection. Clinical data of patients undergoing radical resection of colorectal cancer from January 2019 to December 2021 were retrospectively included in this study. Patients were divided into two groups according to postoperative intra-abdominal infection. Clinicopathological indicators, intraoperative conditions, and postoperative complications were compared between the two groups, logistic regression was used to look for independent risk factors for intra-abdominal infection, and a nomogram was constructed based on independent risk factors. 402 colorectal cancer patients were enrolled in this study, and 46 patients (11.4%) developed intra- abdominal infections after surgery. The independent risk factors for intra-abdominal infection were preoperative albumin, lymphocyte-white cell ratio (LWR) <0.17, low subcutaneous fat mass, and low skeletal muscle mass. The nomogram model for intra-abdominal infection was able to reliably quantify the risk of intraabdominal infection with strong optimism-adjusted discrimination (concordance index=0.931). Furthermore, decision curve analysis showed that the nomogram was clinically useful and had a better discriminative ability to recognize patients at high risk than the risk factors alone. In conclusion, we found that preoperative albumin, LWR <0.17, low subcutaneous fat mass, and low skeletal muscle mass were significantly correlated with intra-abdominal infection. Our nomogram was a simple and practical instrument to quantify the individual risk of intra-abdominal infection.

Preoperative serum albumin is associated with intra-abdominal infection following major hepatectomy.

BackgroundMajor hepatectomy is a complex surgical procedure with high morbidity. Intra‐abdominal infection (IAI) is common following hepatectomy and affects treatment outcomes. This study was performed to investigate perioperative factors and determine whether the preoperative serum albumin level is associated with IAI following major hepatectomy.MethodsFrom January 2008 to December 2018, 268 patients underwent major hepatectomy. We retrospectively analyzed demographic data and preoperative and perioperative variables. IAI was defined as organ/space surgical site infection. Risk factors for IAI were analyzed by logistic regression analysis.ResultsIn total, 268 patients were evaluated. IAI was observed in 38 patients (14.6%). The mortality rate in the IAI group was 15.7%. Multivariate logistic analysis confirmed that the serum albumin level (odds ratio 0.91; 95% confidence interval 0.84–0.97; P = 0.03) and operative duration (odds ratio 1.50; 95% confidence interval 1.18–1.91; P < 0.01) were independent factors associated with IAI. A logistic model using the serum albumin level and operative duration to estimate the probability of IAI was analyzed. The area under the receiver operating characteristic curve for predicting IAI was 0.78.ConclusionThe serum albumin level and operative duration were independent factors predicting IAI following major hepatectomy.

Intra-abdominal infection (IAI) following cesarean section: a retrospective study in a tertiary referral hospital in Egypt

BackgroundThe incidence of post cesarean intra-abdominal infection (IAI) and the independent risk factors associated with it were retrospectively studied at a tertiary referral hospital in Egypt.MethodsThe study targeted the period between January 2014 and December 2017 (4 years) at Minia University Hospital for Obstetrics and Gynecology (a tertiary referral hospital), Minia Governorate, Egypt. All cases that developed IAI following cesarean section (CS) during the study period were included (408 cases, which served as the case group); in addition, 1300 cases that underwent CS during the study period and were not complicated by IAI or surgical site Infection (SSI) were randomly chosen from the records (control group). The records of cases and controls were compared and bivariate analysis and multivariate logistic regression were used to identify risk factors for IAI.ResultsDuring the studied period, there were 35,500 deliveries in the hospital, and 14200 cases (40%) of these were by cesarean section, producing a rate of 40%. The incidence of IAI post CS was 2.87%, and the mortality rate was 1.2% (due to septicemia). The most identifiable risk factors for IAI were chorioamnionitis (AOR 9.54; 95% CI =6.15–16.2; p ≤ 0.001) and premature rupture of membranes (PROM) (AOR 7.54; 95% CI =5.69–10.24; p ≤ 0.001). Risk factors also included: prolonged duration of CS > 1 h (AOR 3.42; 95% CI =2.45–5.23; p = 0.005), no antenatal care (ANC) visits (AOR 3.14; 95% CI =2.14–4.26; p = 0.003), blood loss > 1000 ml (AOR 2.86; 95% CI =2.04–3.92; p = 0.011), emergency CS (AOR 2.24; 95% CI =1.78–3.29; p = 0.016), prolonged labor ≥24 h. (AOR 1.76; 95% CI =1.26–2.27; p = 0.034) and diabetes mellitus (AOR 1.68; 95% CI =1.11–2.39; p = 0.021).ConclusionsThe incidence of IAI post CS in our hospital was 2.87%. Identification of predictors and risk factors for IAI is an important preventive measure.

Does Intra-Abdominal Infection after Curative Gastrectomy Affect Patients' Long-Term Prognosis? A Multi-Center Study Based on a Large Sample Size.

Background: The objective of the study was to investigate the effects of intra-abdominal infection after curative gastrectomy on the prognosis of patients. Patients and Methods: Data were collected for enrolled patients who underwent curative gastrectomy in two centers; the relationship between intra-abdominal infection and prognosis was analyzed. Results: Of the 5,721 patients in the entire group, intra-abdominal infection occurred in 202 (3.5%) patients. Co-morbidities and duration of surgical procedures ≥240 minutes represented the independent risk factors for intra-abdominal infection. The overall five-year survival of patients with and without intra-abdominal infection was 60.2% and 64.3%, respectively (p = 0.041). After propensity score matching, the five-year overall survival between the two groups was not significantly different (p = 0.909). T staging, N staging, American Society of Anesthesiologists score, and age were independent prognostic factors for the overall survival of patients who underwent curative gastrectomy. The meta-analysis of the random effects model showed that there were no significant differences in the five-year overall survival between patients with and without intra-abdominal infection. Conclusions: The development of intra-abdominal infection after curative gastrectomy is associated closely with co-morbidities and longer operation time, whereas intra-abdominal infection does not lead to reduced long-term survival of patients.

Low risk of intra-abdominal infections in rectal cancer patients treated with Hartmann\u2019s procedure: a report from a national registry

PurposeTo describe the postoperative surgical complications in patients with rectal cancer undergoing Hartmann’s procedure (HP).MethodsData were retrieved from the Swedish Colorectal Cancer Registry for all patients with rectal cancer undergoing HP in 2007–2014. A retrospective analysis was performed using prospectively recorded data. Characteristics of patients and risk factors for intra-abdominal infection and re-laparotomy were analysed.ResultsOf 10,940 patients resected for rectal cancer, 1452 (13%) underwent HP (median age, 77 years). The American Society of Anesthesiologists (ASA) score was 3–4 in 43% of patients; 15% had distant metastases and 62% underwent a low HP. The intra-abdominal infection rate was 8% and re-laparotomy rate was 10%. Multivariable logistic regression analysis identified preoperative radiotherapy (OR, 1.78; 95% CI, 1.14–2.77), intra-operative bowel perforation (OR, 1.99; 95% CI, 1.08–3.67), T4 tumours (OR, 1.68; 95% CI 1.04–2.69) and female gender (OR, 1.73; 95% CI, 1.15–2.61) as risk factors for intra-abdominal infection. ASA score 3–4 (OR, 1.62; 95% CI, 1.12–2.34), elevated BMI (OR, 1.05; 95% CI, 1.02–1.09) and female gender (OR, 2.06; CI, 1.41–3.00) were risk factors for re-laparotomy after HP. The rate of intra-abdominal infection was not increased after a low HP.ConclusionsDespite older age and co-morbidities including more advanced cancer, patients undergoing Hartmann’s procedure had low rates of serious postoperative complications and re-laparotomy. A low HP was not associated with a higher rate of intra-abdominal infection. HP seems to be appropriate for old and frail patients with rectal cancer.

Risk Factors for Intra-Abdominal Infection after Pancreaticoduodenectomy – A Retrospective Analysis to Evaluate the Significance of Preoperative Biliary Drainage and Postoperative Pancreatic Fistula

Intra-abdominal infection (IAI) after pancreaticoduodenectomy (PD) is a common cause of prolongation of postoperative hospital stay and readmission to the hospital following discharge. Two hundred and six patients undergoing PD were reviewed to investigate the risk factors for IAI after PD. Patients were separated into two groups: those who developed IAI after PD (Group A; n=44), and those who had not developed IAI after PD (Group B; n=162), the two groups were then compared to identify the risk factors for IAI after PD. A hundred and six patients (51.5%) underwent preoperative biliary drainage (PBD). Multivariate analysis revealed that pancreatic fistula (PF) was an independent risk factor for IAI after PD (p<0.001; odds ratio=9.58; 95% confidence interval=4.37-21.0), but PBD was not a significant risk factor. We demonstrated that the adequate PBD might not affect IAI after PD. On the other hand, PF was an independent risk factor for IAI after PD. A large randomized controlled trial, which would prove the effect of early removal of a prophylactic placed drain to prevent IAI, should be planned.

Risk factors and management of intra-abdominal infection after extended radical gastrectomy

Background This study elucidated risk factors and management for intra-abdominal infection after extended radical gastrectomy. Methods From 1988 to 2004, 2,076 patients with gastric cancer underwent extended radical gastrectomy at Taipei Veterans General Hospital. Risk factors for intra-abdominal infection were determined by analyzing clinicopathological factors, operative procedure, combined organ resection, operative time, blood loss, and associated disease(s). Management modalities were summarized. Results The overall complication rate was 18.7%. Eighty (3.9%) patients were found to have intra-abdominal infections. Age, prolonged operation time, and combined organ resection were the precipitating factors. These patients were categorized into 3 groups: intra-abdominal abscess with adequate drainage, intra-abdominal abscess without anastomotic leakage, and intra-abdominal abscess because of leakage. Adequate drainage was the primary treatment. Mortality rate was 22.5% (18), and the most common cause of mortality was intra-abdominal abscess caused by leakage. Conclusions Although expert surgical skills can minimize the incidence of intra-abdominal infection, management also requires experience and training.

Risk factors for intra-abdominal infection after pancreas transplantation

Background: This study was designed to determine risk factors for intra-abdominal abscess after pancreas transplantation. Methods: We performed a single-center retrospective review of all pancreas transplants from 1994 to 1999. Risk factors studied were donor age, body weight, body mass index, peak serum glucose, peak serum amylase, need for pressor agents, cause of death, cold ischemic preservation time, recipient age, type of dialysis, surgical technique, and peak recipient amylase. Results: The 1-year graft survival rate was 90%. Of the 34 patients studied, there were 4 cases of peripancreatic abscess formation (12%). Elevated donor body weight ( P <0.01), elevated body mass index ( P <0.05), and the peak recipient serum amylase in the first postoperative week ( P <0.01) were significant risk factors for the development of intra-abdominal infection. Conclusions: These data suggest that pancreas grafts from obese donors may be more susceptible to ischemia-reperfusion injury resulting in abscess formation.
