Aminoglycoside antibiotics as first-line treatment of acute appendicitis and cholecystitis.

We analyzed the efficacy and safety of aminoglycosides in a retrospective study of 415 patients with acute appendicitis and 277 patients with acute cholecystitis. The following variables increased the incidence of postoperative complications, defined as surgical site infection, recurrent intraabdominal infection, non-infectious post-operative complication, or death: age (p = 0.016 and 0.011), kidney disease (p = 0.019 and <0.001), and ASA Score (p < 0.001). The type of antibiotic therapy did not have a statistically significant effect on the incidence of postoperative complications in patients with acute appendicitis and cholecystitis (p = 0.561 and 0.547, respectively). A linear regression model showed a higher complication rate in patients with kidney disease (p = 0.014) and neoplasms (p = 0.013); the type of antibiotic therapy did not have a significant effect on the outcome (p = 0.765). There was no statistically significant difference in the post-treatment levels of creatinine in patients treated with aminoglycosides (gentamicin 3 mg/kg once daily) and in those who received other antibiotics (p = 0.75).

Next-generation microbiological testing in intraabdominal infections with PCR technology.

PURPOSE: Intraabdominal infections (IAI) are increasing worldwide and are a major contributor to morbidity and mortality. Among IAI, the number of multi-drug resistant organisms (MDRO) is increasing globally. We tested the Unyvero A50® for intraabdominal infections, compared the detected microorganisms and antibiotic resistance, and compared the results with those of routine microbiology. METHODS: We prospectively compared samples obtained from surgical patients using PCR-based Unyvero IAI cartridges against routine microbiology for the detection of microorganisms. Additionally, we identified clinical parameters that correlated with the microbiological findings. Data were analyzed using the t-test and Mann-Whitney U test. RESULTS: Sixty-two samples were analyzed. The PCR system identified more microorganisms, mostly Bacteroides species, Escherichia coli, and Enterococcus spp. For bacterial resistance, the PCR system results were fully concordant with those of routine microbiology, resulting in a sensitivity, specificity, and positive and negative predictive value (PPV, NPV) of 100%. The sensitivity, specificity, PPV, and NPV for the detection of microorganisms were 74%, 58%, 60%, and 72%, respectively. CRP levels were significantly higher in patients with detectable microorganisms. We identified more microorganisms and bacterial resistance in hospital-acquired intra-abdominal infections by using the PCR system. DISCUSSION: IAI warrants early identification of the microorganisms involved and their resistance to allow for adequate antibiotic therapy. PCR systems enable physicians to rapidly adjust their antibiotic treatment. Conventional microbiological culture and testing remain essential for determining the minimal growth inhibition concentrations for antibiotic therapy.

Efficacy and safety of tazobactam/ceftolozane in combination with metronidazole for intraabdominal infection in a hepato-biliary-pancreatic field in clinical practice.

INTRODUCTION: This single-center study evaluated the efficacy and safety of tazobactam/ceftolozane (TAZ/CTLZ) in combination with metronidazole for intraabdominal infection in a hepato-biliary-pancreatic field in clinical practice. METHODS: This study included 50 patients, including 35 with intraabdominal abscess or peritonitis, 5 with liver abscess, 4 with cholecystitis, and 6 with cholangitis with sepsis. Of the 50 patients, 29 received TAZ/CTLZ and metronidazole after a prior antibacterial therapy failure, including tazobactam/piperacillin, cefmetazole, and levofloxacin. Source control was performed in 36 patients. RESULTS: The clinical response could be evaluated in 49 patients. The clinical cure rate at end-of-therapy was 91.8% (45 of 49 patients) and that at test-of-cure was 89.6% (43 of 48 patients). Of 5 patients in whom clinical response at test-of-cure was a failure, 1 developed infectious disease during chemoradiotherapy for recurrent cancer and 4 after liver resection or pancreatoduodenectomy. Three of the 4 patients were associated with pancreatic juice leakage. Isolated pathogens were eradicated or presumably eradicated in 27 of 31 (87.1%) patients in whom microbiological response at test-of-cure could be evaluated. The response rate for AmpC-producing Enterobacteriaceae was 87.5%. Nausea was observed in two patients. Aspartate and alanine aminotransferase activities were increased in 3 of the 50 (6.0%) patients. The activities improved after the antibiotic discontinuation. CONCLUSIONS: This observational study demonstrated that TAZ/CTLZ in combination with metronidazole has a favorable effect without major drug-related adverse events for intraabdominal infection in the hepato-biliary-pancreatic field in clinical practice although the efficacy of TAZ/CTLZ may decrease in compromised patients.

Effects of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection in mainland China: a meta-analysis

SUMMARY OBJECTIVE: The aim of this study was to explore the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection in mainland China using meta-analysis. METHODS: We searched China National Knowledge Network, Wanfang Medical Network, Chinese Science Citation Database, PubMed, and Embase Databases for publications of imipenem combined with glutamine in the treatment of severe acute pancreatitis abdominal infection. The search time limit was from the establishment of the database to April 10, 2021. Stata software version 12.0 was used for statistical analysis; the combined effect size odds ratio and standardized mean difference values were calculated for the count data and measurement data, respectively; and the heterogeneity test was performed in this study. RESULTS: A total of five randomized controlled trials were included. A total of 499 cases were included, with 251 in the observation group and 248 in the control group. Meta-analysis results showed that the efficacy of imipenem combined with glutamine in the treatment of severe acute pancreatitis with abdominal infection was significantly better than that of imipenem alone (odds ratio=0.78, 95%CI 0.71-0.86, p=0.040). CONCLUSION: Imipenem combined with glutamine can significantly improve the efficacy in the treatment of severe acute pancreatitis with abdominal cavity infection.

Diagnosis and Management of Intraabdominal Infection: Guidelines by the Chinese Society of Surgical Infection and Intensive Care and the Chinese College of Gastrointestinal Fistula Surgeons.

The Chinese guidelines for IAI presented here were developed by a panel that included experts from the fields of surgery, critical care, microbiology, infection control, pharmacology, and evidence-based medicine. All questions were structured in population, intervention, comparison, and outcomes format, and evidence profiles were generated. Recommendations were generated following the principles of the Grading of Recommendations Assessment, Development, and Evaluation system or Best Practice Statement (BPS), when applicable. The final guidelines include 45 graded recommendations and 17 BPSs, including the classification of disease severity, diagnosis, source control, antimicrobial therapy, microbiologic evaluation, nutritional therapy, other supportive therapies, diagnosis and management of specific IAIs, and recognition and management of source control failure. Recommendations on fluid resuscitation and organ support therapy could not be formulated and thus were not included. Accordingly, additional high-quality clinical studies should be performed in the future to address the clinicians' concerns.

Hallazgos microbiológicos y susceptibilidad antimicrobiana en cirugía abdominal de urgencia / Microbiological findings and antimicrobial susceptibility in emergency abdominal surgery

Resumen Introducción: Es importante mantener programas de vigilancia bacteriana para disminuir resistencia y definir esquemas farmacológicos adecuados. Los pacientes con abdomen agudo representan un grupo microbiológico especial. Objetivos: Hacer una revisión de agentes patógenos en pacientes adultos operados en nuestro Servicio de Urgencia por patología abdominal con líquido libre y analizar los resultados obtenidos de cultivos respecto a las cepas y la susceptibilidad a los antibióticos. Materiales y Método: Estudio de cohorte prospectiva con estadística descriptiva. Se incluyen pacientes consecutivos, mayores de 18 años, operados por abdomen agudo que presentan líquido libre intraperitoneal entre noviembre de 2017 y abril de 2018. Se excluyen casos con terapia antimicrobiana, hospitalización y/o cirugía en los 3 meses previos. Se registran los cultivos positivos, cepas aisladas, susceptibilidad antimicrobiana, datos demográficos y evolución clínica. Resultados: De 63 pacientes 55% fueron hombres, edad promedio 52,2 años. Las patologías más frecuentes fueron de origen apendicular (62%) y de causa entérica (30%). En un 44% el cultivo fue positivo y en 36% con más de un germen. Escherichia coli fue el patógeno más frecuente (64,2%) seguidos de Enterococcus faecium y Streptococcus anginosus (7,1%). De los otros patógenos cultivados sólo se observó resistencia múltiple en un caso aislado de Morganella Morganii. Conclusiones: Estos datos constituyen la realidad microbiológica local en abdomen agudo. La Escherichia Coli sigue siendo el germen más frecuente, debe enfrentarse con profilaxis y tratamiento antibiótico adecuado. Es necesario mantener vigilancia microbiología local para un manejo acorde.

Introduction: It is important to maintain bacterial surveillance programs to decrease resistance and define adequate pharmacological schemes. Patients with abdomen represent a special microbiological group. Objetives: Make a review of pathogens in adult patients operated in our Emergency Service for abdominal pathology with free fluid and analyze the results obtained from cultures with respect to the strains and susceptibility to antibiotics. Materials and Method: Prospective cohort study with descriptive statistics. We include consecutive patients, older than 18 years old, operated on by abdomen who present free intraperitoneal fluid between November 2017 and April 2018. Cases with antimicrobial therapy, hospitalization and/or surgery 3 months prior are excluded. Positive cultures, isolated strains, antimicrobial susceptibility, demographic data and clinical evolution are recorded. Results: Of 63 patients, 55% were men and the average age was 52.2 years. The most frequent pathologies were of appendicular origin (62%) and of enteric origin (30%). In 44% the crop was positive and in 36% with more than one germ. Escherichia coli was the most frequent pathogen (64.2%) followed by Enterococcus faecium and Streptococcus anginosus (7.1%). Of the others, cultivated pathogens have only observed multiple resistance in an isolated case of Morganella Morganii. Conclusions: These data include the local microbiological reality in acute abdomen. Escherichia coli is still the most frequent germ that must be faced with the profile and the appropriate treatment. It is necessary to maintain local microbiology surveillance for a proper management.

Shorter Total Length of Stay After Intraperitoneal Fosfomycin, Metronidazole, and Molgramostim for Complicated Appendicitis: A Pivotal Quasi-Randomized Controlled Trial.

Background: We aimed to investigate the difference in the total length of hospital stay (LOS) after intraperitoneal vs. intravenous antibiotic treatment in patients with complicated appendicitis. Methods: We conducted a quasi-randomized prospective clinical trial. The intervention group received 4 g fosfomycin, 1 g metronidazole, and 50 µg recombinant human granulocyte-macrophage colony-stimulating factor intraperitoneally, which was left in the abdominal cavity, immediately after laparoscopic appendectomy. Postoperatively, this group received antibiotics orally. The control group received intravenous antibiotics both during surgery and postoperatively. We primarily evaluated total LOS within 30 days. Furthermore, we evaluated harms and adverse events, Gastrointestinal Quality of Life Index, postoperative complications, and convalescence. Participants were followed for 30 days postoperatively. Results: A total of 12 participants concluded the trial. The total LOS was significantly shorter in the intervention group (six participants, median 13 h; range 2-21 h) than in the control group (six participants, median 84 h; range 67-169 h), p = 0.017. Comparable harms and Gastrointestinal Quality of Life Index scores were found in the two groups. The time to return to normal activities was median 6 and 10 days for the intervention and the control group, respectively. There were no serious adverse events related to the trial nor any complications in the intervention group. In the control group, two patients developed intraabdominal abscesses. Conclusions: The intervention group had a significantly shorter total LOS. The study was not powered to assess differences in complications, but the results indicate that the intervention seems to be a safe regimen, which can be investigated further to treat patients with complicated appendicitis. Identifiers: EudraCT no. 2017-004753-16. ClinicalTrials: https://clinicaltrials.gov/ct2/show/NCT03435900?term=NCT03435900&draw=2&rank=1">draw=2&rank=1.

Splenic mass of uncertain etiology in a 15-year-old male patient: a case report.

BACKGROUND: There are few reports on spleen masses, and solitary splenic abscesses with abdominal pain have not been reported in younger age groups. We report a case of a splenic mass of uncertain etiology in a 15-year-old boy. CASE PRESENTATION: A 15-year-old boy visited the emergency department with abdominal pain. Abdominal ultrasonography revealed a thin-walled multilobular splenic cyst. Computed tomography revealed a cystic shadow and a septate structure in the spleen. Magnetic resonance imaging examination revealed a high-signal region on the T2-weighted image. The neutrophil ratio in the white blood cell count of 8,330/µL was high (80%), and splenic abscess could not be ruled out. Thus, therapy with 2 g/day fosfomycin was initiated. Abdominal pain disappeared on day 3 of hospital stay, and the patient was discharged on day 8. CONCLUSION: Antibiotic therapy can be effective against very acute onset splenic abscesses, although surgical treatment is usually carried out.

Are reactive C protein and procalcitonin useful for early diagnosis of postoperative intraabdominal infection after pancreaticoduodenectomy for pancreatic cancer?

OBJECTIVE: To evaluate the relationship between C reactive protein and procalcitonin levels and the appearance of post-operative intraabdominal infection, in patients with pancreaticoduodenectomy due to pancreatic cancer. METHOD: A prospective observational study, including 35 patients, was made. Procalcitonin and C reactive protein were measured before surgery, as well as 24, 48 and 72 h after the surgical procedure. Patients were divided in two groups, with and without intraabdominal infection. RESULTS: Six patients (17.1%) presented post-operative intraabdominal infection. Both, procalcitonin and C reactive protein, increased in all patients after surgery, but there were no significant differences between the two groups. However, the ratio between the C reactive protein concentrations on post-operative day 3 and the concentrations on post-operative day 1 was significantly increased in the group of patients with intraabdominal infection. The predictive positive value and the predictive negative value for this ratio were 60% and 95%, respectively, for a cut-off point of 2.3. CONCLUSIONS: The ratio between C reactive protein value on post-operative day 3 and the value on post-operative day 1 is a good predictor of post-operative intraabdominal infection after pancreaticoduodenectomy.

OBJETIVO: Evaluar la relación entre los valores de proteína C reactiva y de procalcitonina y la aparición de infección intraabdominal posoperatoria en pacientes con duodenopancreatectomía por cáncer de páncreas. MÉTODO: Estudio prospectivo observacional que incluye 35 pacientes. Ambos parámetros se midieron antes de la cirugía y a las 24, 48 y 72 horas de la intervención. Los pacientes se dividieron en dos grupos: con y sin infección intraabdominal. RESULTADOS: Seis pacientes (17.1%) tuvieron infección intraabdominal. Ambos parámetros aumentaron en todos los pacientes tras la cirugía, pero no hubo diferencias significativas entre los dos grupos. Sin embargo, el cociente entre los valores de proteína C reactiva en el día 3 y los valores en el día 1 de posoperatorio era significativamente mayor en los pacientes con infección intraabdominal, con un valor predictivo positivo del 60% y un valor predictivo negativo del 95%, para un punto de corte de 2.3. CONCLUSIONES: El cociente entre las concentraciones séricas de proteína C reactiva en el tercer día y en el primer día de posoperatorio es un buen predictor de infección intraabdominal posoperatoria después de una duodenopancreatectomía.

Enhanced recovery after surgery in emergency colorectal surgery: Review of literature and current practices.

Enhanced recovery after surgery (ERAS), a multidisciplinary program designed to minimize stress response to surgery and promote the recovery of organ function, has become a standard of perioperative care for elective colorectal surgery. In an elective setting, ERAS program has consistently been shown to decrease postoperative complication, reduce length of hospital stay, shorten convalescence, and lower healthcare cost. Recently, there is emerging evidence that ERAS program can be safely and effectively applied to patients with emergency colorectal conditions such as acute colonic obstruction and intraabdominal infection. This review comprehensively covers the concept and application of ERAS program for emergency colorectal surgery. The outcomes of ERAS program for this emergency surgery are summarized as follows: (1) The ERAS program was associated with a lower rate of overall complication and shorter length of hospital stay - without increased risks of readmission, reoperation and death after emergency colorectal surgery; and (2) Compliance with an ERAS program in emergency setting appeared to be lower than that in an elective basis. Moreover, scientific evidence of each ERAS item used in emergency colorectal operation is shown. Perspectives of ERAS pathway in emergency colorectal surgery are addressed. Finally, evidence-based ERAS protocol for emergency colorectal surgery is presented.

PK/PD Target Attainment With Ceftolozane/Tazobactam Using Monte Carlo Simulation in Patients With Various Degrees of Renal Function, Including Augmented Renal Clearance and End-Stage Renal Disease.

INTRODUCTION: Ceftolozane/tazobactam is an antibacterial agent with potent in vitro activity against Gram-negative pathogens, including many extended-spectrum ß-lactamase-producing Enterobacteriaceae and drug-resistant Pseudomonas aeruginosa. Because ceftolozane/tazobactam is primarily excreted renally, appropriate dose adjustments are needed for patients with renal impairment. Monte Carlo simulations were used to determine the probability of pharmacokinetic/pharmacodynamic target attainment for patients with varying degrees of renal function, including augmented renal clearance (ARC) and end-stage renal disease (ESRD) with hemodialysis. METHODS: Monte Carlo simulations were conducted for 1000 patients with ARC and normal renal function, mild renal impairment, moderate renal impairment, or severe renal impairment, and for 5000 patients with ESRD. Simulated dosing regimens were based on approved doses for each renal function category. Attainment targets for ceftolozane were 24.8% (bacteriostasis), 32.2% (1-log kill; bactericidal), and 40% (2-log kill) fT > minimum inhibitory concentration (MIC). The target for tazobactam was to achieve a 20% fT > minimum effective concentration (MEC) at an MEC of 1 mg/L, which was derived from a neutropenic mouse thigh infection model and was confirmed by efficacy data from clinical studies for complicated intraabdominal infections and complicated urinary tract infections. RESULTS: In patients with ARC or normal renal function, ≥91% achieved bactericidal activity (32.2% fT > MIC) up to an MIC of 4 mg/L with a 1000-mg ceftolozane dose. In patients with renal impairment (mild, moderate, severe, ESRD), ≥93% achieved bactericidal activity up to an MIC of 8 mg/L. In patients of all renal function categories, the approved dosing regimens of tazobactam achieved ≥91% target attainment against a target of 20% fT > MEC. CONCLUSIONS: At the approved dosing regimens for ceftolozane/tazobactam, ≥91% of patients in all renal function categories, including ARC (up to 200 mL/min) and ESRD, reached target attainment for bactericidal activity at MICs that correspond to susceptibility breakpoints for Enterobacteriaceae and P. aeruginosa.

Intraabdominal Infections in Older Adults.

Intraabdominal infections represent a diagnostic and therapeutic challenge in the elderly population. Atypical presentations, diagnostic delays, additional comorbidities, and decreased physiologic reserve contribute to high morbidity and mortality, particularly among frail patients undergoing emergency abdominal surgery. While many infections are the result of age-related inflammatory, mechanical, or obstructive processes, infectious complications of feeding tubes are also common. The pillars of treatment are source control of the infection and judicious use of antibiotics. A patient-centered approach considering the invasiveness, risk, and efficacy of a procedure for achieving the desired outcomes is recommended. Structured communication and time-limited trials help ensure goal-concordant treatment.
