Spontaneous bacterial peritonitis (SBP) in patients with cirrhotic liver disease is a serious complication that contributes to the high morbidity and mortality rate seen in this population. Currently, there is a lack of consensus amongst the research community on the clinical predictors of SBP as well as the risks and benefits of prophylactic antibiotic therapy in these patients. Pharmacological gastric acid suppression (namely with PPIs and H2RAs) are frequently prescribed for these patients, many times without a clear indication, and may contribute to gut bacterial overflow and SBP development. However, this remains controversial as there are conflicting findings in SBP prevalence between PPI/H2RA-users and non-users. In addition, studies show recent antibiotic use, whether for SBP prophylaxis or for another infectious process, appear to be associated with higher rates of SBP and drug-resistant organisms. Other researchers have also explored the link between zinc, platelet indices (MPV), and macrophage inflammatory protein-1 β (MIP-1β) levels in liver cirrhosis, all of which appear to be promising markers for classifying SBP risk and diagnosis. This literature review was limited by the number and quality of studies available as most are retrospective in nature. Thus, more ongoing, prospective studies and trials are needed to judge the true value of the findings in the studies reviewed in hopes that they can guide appropriate prevention, diagnosis, and management of SBP. 展开更多

BACKGROUND Neisseria mucosa is a gram negative diplococcus belonging to the genus Neisseria found commonly in the upper respiratory tract.It is typically a commensal organism when it is parasitic on oral and nasal mucosa.To our knowledge,it does not cause disease in healthy individuals with normal immunity,but can be pathogenic in those with impaired immune function or change in bacterial colonization site.Neisseria mucosa has been reported to cause bacterial meningitis,conjunctivitis,pneumonia,endocarditis,peritonitis and urethritis.However,peritoneal dialysis-related peritonitis caused by Neisseria mucosa is extremely rare in clinical practice,which has not previously been reported in China.CASE SUMMARY A 55-year-old female presented to the nephrology clinic with upper abdominal pain without apparent cause,accompanied by nausea,vomiting and diarrhea for two days.The patient had a history of Stage 5 chronic kidney disease for five years,combined with renal hypertension and renal anemia,and was treated with peritoneal dialysis for renal replacement therapy.The patient was subsequently diagnosed with peritoneal dialysis-related peritonitis.Routine examination of peritoneal dialysis fluid showed abdominal infection,and the results of microbial culture of the peritoneal dialysis fluid confirmed Neisseria mucosa.Imi-penem/cilastatin 1.0 g q12h was added to peritoneal dialysis fluid for anti-infection treatment.After 24 d,the patient underwent upper extremity arteriovenous fistulation.One month later,the patient was discharged home in a clinically stable state.CONCLUSION Peritonitis caused by Neisseria mucosa is rare.Patients with home-based self-dialysis cannot guarantee good medical and health conditions,and require education on self-protection. 展开更多

Objective: Describe the perioperative management of peritonitis in surgical emergencies. Methodology: This was a prospective observational study of the descriptive type over a period of 12 months from January 01 to December 31, 2020 in the surgical emergency room at the CHU Ignace Deen. Included in the study were all patients admitted for peritonitis aged greater than or equal to 18 years. The parameters were epidemiological, clinical and anesthetic. Results: Of the 653 admissions to surgical emergencies in 2020, 185 cases presented with peritonitis, i.e. 29.3%. The average age was 38.6 ± 16.64 years with extremes of 18 and 90 years. The sex ratio was 1.89. The comorbidities were dominated by gastritis and hypertension, i.e. 22%. The patients were classified as ASA 3U (52.4%), ASA2 U (39.5%) and ASA 4 U (8.1%). Preoperative resuscitation was provided only with 100% saline. 25.5% of patients had received a blood transfusion. The response time was less than 48 hours, i.e. 77.6%. General anesthesia was performed for all patients. Ketamine was the most used IV hypnotic (56.3%) combined with 100% halothane. The curares used were suxamethonium at (81.6%), Atracurium (81.6%) and rocuronium at (18.3%). Fentanyl was the only morphine used. Senior anesthesia technicians provided anesthesia in (63.2%). Intraoperative incidents were dominated by hypotension, difficult intubation, cardiac arrest, respectively 10.3%, 8% and 0.5%.

It is most often secondary to perforation of the digestive organ and/or the spread of an intra-abdominal septic focus. The absence of a study on peritonitis in a reference health center motivated us for this work. The aim of this study was to study the inadequacies that could be seen in the management of peritonitis in the CSRef(s). We carried out a retrospective study of 40 patients received at the CSRéf of commune I for acute generalized peritonitis from 2011 to 2012. The average age was 30.1 years with a standard deviation of 3.4;extremes ranging from 14 years to 60 years and a Sex ratio = 1.22 (22 men out of 18 women). Abdominal pain was the main reason for consultation (present in all our patients). In most cases, clinical examination alone made it possible to make the diagnosis. Surgical treatment depended on the etiology (appendectomy associated with washing-drainage was the most commonly performed surgical procedure). All our patients received general anesthesia. The average length of hospitalization was 7 days with extremes ranging from 1 to 15 days. We noted a Morbidity rate of 22.5%, dominated by wall abscesses and a mortality of 2.5%. The delay in consultation and referrals constitutes a factor in mortality and high morbidity. 展开更多

Acute peritonitis is most often secondary to perforation of the digestive organ and/or the spread of an intra-abdominal septic focus. The objectives of this work were to study acute peritonitis in the general surgery department of the Cs ref of commune I in Mali, to determine the frequency of peritonitis, to describe the epidemiological, clinical and therapeutic aspects in order to analyze the surgical consequences and to assess the additional cost of treating acute peritonitis. This study was prospective, descriptive, cross-sectional involving 40 patients received in the surgery department of the Cs ref of commune I for acute peritonitis from January 1, 2018 to December 31, 2018. There were 40 patients among whom 28 (70%) were men and 12 were women (30%), i.e. a sex ratio = 2.3. The average age was 25 years with extremes varying between 16 and 54 years and a standard deviation of 11.78. Abdominal pain was the main reason for consultation. Clinical examination alone made it possible to make the diagnosis in 75% of cases. Surgical treatment depended on the intraoperative etiology. The clinical diagnosis was supported by ASP and abdominal ultrasound;performed respectively in 10% and 90% of patients. Appendiceal peritonitis was the intraoperative diagnosis observed in 50% of cases. All our patients benefited from a peritoneal toilet with drainage. We noted a morbidity rate of 5% dominated by parietal suppuration. The average cost of care was 175,000 FCFA. 展开更多

BACKGROUND The concept of mandatory laparotomy in treating traumatic peritonitis has been increasingly questioned recently.AIM To summarize and share the experience of conservative treatment of patients with multi-trauma induced peritonitis.METHODS A retrospective review was performed on patients with multiple injury induced traumatic peritonitis.RESULTS A total of 184 patients with multiple injury induced traumatic peritonitis were reviewed.46 of them underwent conservative treatment.None of the 46 patients with conservative treatment switched to surgical treatment,and all of them were cured and discharged after successful conservative treatment.No significant abnormal findings were observed at regular follow-up after discharge.CONCLUSION Conservative management is safe,effective,feasible,and beneficial in hemodynamically stable patients with traumatic peritonitis if there is no definite evidence of severe abdominal visceral organ injury. 展开更多
