Project description:The current work attempts to highlight the various life threatening complications of Meckel's diverticulum and to present the surgical strategies used in the emergency conditions so far in the form of a review of the works presented in the literature. Our aim behind this presentation is to cover the possible indications, methods, their complications and the outcome of these surgical techniques. For this, we made an extensive literature search using Google and Pubmed with the words-"Meckel's diverticulum", "Complications", "Management" and "Emergency surgery". All the relevant articles containing the surgical aspects of symptomatic Meckel's diverticulum till May 2008 were collected and analyzed. Meckel's diverticulum is the remains of the prenatal yolkstalk (Vitellointestinal duct). Although it generally remains silent but life threatening complications may arise making it an important structure for having a detailed knowledge of its anatomical and pathophysiological properties to deal with such complications.

Project description:BackgroundWe sought to systematically review the existing research on pyogenic liver abscesses to determine what data exist on antibiotic treatment durations.MethodsWe conducted a systematic review and meta-analysis of contemporary medical literature from 2000 to 2020, searching for studies of pyogenic liver abscesses. The primary outcome of interest was mean antibiotic treatment duration, which we pooled by random-effects meta-analysis. Meta-regression was performed to examine characteristics influencing antibiotic durations.ResultsSixteen studies (of 3,933 patients) provided sufficient data on antibiotic durations for pooling in meta-analysis. Mean antibiotic durations were highly variable across studies, from 8.4 (SD 5.3) to 68.9 (SD 30.3) days. The pooled mean treatment duration was 32.7 days (95% CI 24.9 to 40.6), but heterogeneity was very high (I2 = 100%). In meta-regression, there was a non-significant trend towards decreased mean antibiotic treatment durations over later study years (-1.14 days/study year [95% CI -2.74 to 0.45], p = 0.16). Mean treatment duration was not associated with mean age of participants, percentage of infections caused by Klebsiella spp, percentage of patients with abscesses over 5 cm in diameter, percentage of patients with multiple abscesses, and percentage of patients receiving medical management. No randomized trials have compared treatment durations for pyogenic liver abscess, and no observational studies have reported outcomes according to treatment duration.ConclusionsAmong studies reporting on antibiotic durations for pyogenic liver abscess, treatment practices are highly variable. This variability does not seem to be explained by differences in patient, pathogen, abscess, or management characteristics. Future RCTs are needed to guide optimal treatment duration for patients with this complex infection.

Project description:Twenty five cases of Meckel's diverticulum were studied between 1985-1995. Eight of these were symptomatic and in the remaining 17 it was an incidental finding. The symptomatic patients presented with intestinal obstruction (5 cases), perforated peritonitis (2 cases) and intussusception (1 case). All cases of acute appendicitis were also subjected to a search for Meckel's diverticulum. Of the 25 Meckel's diverticuli encountered, 22 were resected and in 3 patients it was left in situ. Both the patients with perforated Meckel's diverticulum showed ectopic gastric mucosa. Complications occurred only after surgery for symptomatic Meckel's diverticulum. All patients undergoing incidental diverticulectomy had a smooth and uncomplicated recovery.

Project description:BACKGROUND: Pyogenic liver abscess is a life-threatening disease. Few studies have specifically explored the way in which the clinical features and management of elderly patients with pyogenic liver abscess differ from those of younger individuals. METHODS: A retrospective study was undertaken to evaluate whether older patients with pyogenic liver abscess have distinctive presenting features or whether their management and outcome differ from that of younger patients. A total of 133 patients with liver abscess treated in five hospitals during 13 years comprised two groups: 78 patients aged 60 years or above (older group) and 55 patients below age 60 years (younger group). Clinical features, laboratory data, imaging and microbiological findings, management and outcome were determined in each group. RESULTS: The older group contained more patients with associated diseases (p=0.03), nausea and vomiting at presentation (p=0.02), higher APACHE II (Acute Physiological and Chronic Health Evaluation II scale) score (p<0.001) and blood urea nitrogen (p<0.001) and serum creatinine levels (p=0.002). Multiple abscess (p=0.05) and bilobar (p=0.03) abscess were also commoner in this group. By contrast, in the younger group men predominated (p=0.01), and there was a higher overall complication rate (p=0.05).Time to diagnosis, hospital mortality rate and other variables analysed were similar in both groups. DISCUSSION: Elderly patients with pyogenic liver abscess have some subtle differences in clinical and laboratory presentation, but these do not appear to delay diagnosis. Active management is tolerated well, with a lower morbidity rate than in younger patients and no difference in the mortality rate.

Project description:BackgroundPyogenic liver abscesses (PLA) remain a significant clinical problem. Unfortunately, little is known about current bacterial susceptibility profiles and the incidence of multidrug resistant organisms (MDROs) causing PLA in Western countries. Yet, this crucial information is pivotal to guide empirical antibiotic therapy. Aim of this study was to provide detailed characteristics of PLA with a special focus on underlying bacterial pathogens and their susceptibility to antibiotics.MethodsA retrospective study of patients diagnosed with PLA from 2009 to 2015 in a large tertiary reference center in Germany was performed in order to characterize PLA and antimicrobial susceptibility profiles of causative bacterial species.ResultsOverall, 86 patients were included. The most common causes of PLA were bile duct stenosis/obstruction (31.4%) and leakage of biliary anastomosis (15.1%). Frequent predisposing diseases were malignancies (34.9%), diabetes (24.4%) and the presence of liver cirrhosis (16.3%). Of note, Enterococcus spp. were the most frequently cultured bacterial isolates (28.9%), and in 1/3 of cases vancomycin resistance was observed. In addition, a relevant frequency of gram-negative MDROs was identified. In particular, an alarming 10% and 20% of gram-negative bacteria were resistant to carbapenems and tigecycline, respectively. Of note, MDRO status did not predict ICU stay or survival in multivariate regression analysis. The mortality rate in our series was 16.3%.ConclusionOur study demonstrates an as yet underreported role of Enterococcus spp., often associated with vancomycin resistance, as well as of gram-negative MDROs causing PLA.

Project description:Several recent studies have demonstrated that virulence in Entamoeba histolytica is triggered in the presence of both pathogenic and nonpathogenic bacteria species using in vitro and in vivo experimental animal models. In this study, we examined samples aspirated from abscess material obtained from patients who were clinically diagnosed with amebic liver abscess (ALA) or pyogenic liver abscess (PLA). To determine the diversity of bacterial species in the abscesses, we performed partial 16S rRNA gene sequencing. In addition, the E. histolytica and Entamoeba dispar species were genotyped using tRNA-linked short tandem repeats as specific molecular markers. The association between clinical data and bacterial and parasite genotypes were examined through a correspondence analysis. The results showed the presence of numerous bacterial groups. These taxonomic groups constitute common members of the gut microbiota, although all of the detected bacterial species have a close phylogenetic relationship with bacterial pathogens. Furthermore, some patients clinically diagnosed with PLA and ALA were coinfected with E. dispar or E. histolytica, which suggests that the virulence of these parasites increased in the presence of bacteria. However, no specific bacterial groups were associated with this effect. Together, our results suggest a nonspecific mechanism of virulence modulation by bacteria in Entamoeba.

Project description:Anaerobic gram-positive bacilli can occasionally be implicated in infections but are difficult to identify in culture by conventional biochemical methods. We report a case of liver abscesses caused by Eggerthella lenta, identified via 16S rRNA sequencing in a previously healthy patient, successfully treated with percutaneous drainage and ertapenem.

Project description:Meckel's diverticulum is a remnant of the omphalomesenteric duct, found only in approximately 2% of the population. Although Meckel's diverticulum is often diagnosed in nonsymptomatic patients as incidental radiologic findings, complications of Meckel's diverticulum can also be seen on radiologic evaluation. We present a rare care of perforated Meckel's diverticulum in a geriatric patient demonstrated on contrast computed tomography. This was later confirmed during laparoscopic surgery with pathologic evaluation.

Project description:Introduction and Importance: Meckel's diverticulum band is an uncommon cause of intestinal obstruction in adults. Case presentation We report the case of a 57-year-old diabetic and hypertensive male who presented with sudden onset of vomiting and abdominal pain. Initial laboratory and imaging investigations, including an abdominal X-ray and computed tomography scan, were suggestive of an intestinal obstruction; however, these were not helpful in assigning a presumptive cause. A laparoscopic exploration was offered after a repeated abdominal X-ray showed an air-fluid level. Intraoperative findings revealed an ischemic closed loop obstructed by a fibrous band of Meckel's diverticulum. Resection and anastomosis of the bowel was performed, and the patient was discharged on day 3 post-operative with no complications. Clinical discussion Surgical resection performed by open or laparoscopic approach is the recommended treatment for patients with symptomatic Meckel's diverticulum. Generally, a wedge resection of the Meckel's diverticulum is performed, and occasionally part of the ileum is resected by end-to-end anastomosis, as was the case in our patient. Conclusion We believe early surgical intervention is crucial for a favorable outcome. Thus, surgeons should consider complicated Meckel's diverticulum in patients presenting with signs and symptoms of small bowel obstruction. Highlights • Intestinal Obstruction Caused by Meckel's Diverticulum Band are extremely rare in adult.• Obstruction Caused by Meckel's Diverticulum Band may present a challenging clinical diagnosis.• Surgical resection remains the treatment of choice and plays a potentially curative role.

Project description:A 38-year-old female presented to the emergency department (ED) with acute-onset right lower quadrant abdominal pain following two days of nausea and vomiting. Physical examination revealed right lower quadrant tenderness to palpation, rebound tenderness, and guarding. Point-of-care ultrasound (POCUS) of the right lower abdomen was performed and interpreted as probable appendicitis. However, upon laparoscopic examination of the abdomen, a benign-appearing appendix was visualized. Further investigation revealed the source of the patient's pain to be a torsed Meckel's diverticulum. Although rare, a torsed and inflamed Meckel's diverticulum can be visualized by POCUS in the ED without the need for further imaging or delay.
