RESUMO

Sarcina ventriculi is a species of Gram-positive bacteria which has been reported in patients with delayed gastric emptying as well as in association with cases of gastric ulcer and gastric carcinoma. Although it has been reported frequently in veterinary cases as a cause of fatal diseases, the exact pathogenesis in humans has yet to be identified. We report here a case of an elderly male who presented with haematemesis following which an upper gastrointestinal endoscopy was done and a gastric ulcer was revealed. Histopathological examination revealed S. ventriculi in association with the ulcer.

RESUMO

Sarcina ventriculi is a bacterium with a specific histological morphology and infection can present with symptoms such as abdominal pain, nausea, vomiting and occasionally fatal complications. Delayed gastric emptying is regarded as the most significant risk factor for infection. Its pathogenicity is currently unknown and treatment options are inconsistent. Here we report a case of gastric bezoars secondary to a mixed infection of Sarcina ventriculi and G + bacilli, which is diagnosed by a pathological biopsy.

RESUMO

Gastric volvulus is a potentially life-threatening condition that can compromise the blood supply to the stomach predisposing to ischemia, eventually necrosis and cell death associated with gas-forming bacteria. Sarcina ventriculi has been associated with emphysematous gastritis also. We report a case of emphysematous gastritis associated with S. ventriculi in the setting of organo-axial gastric volvulus.

RESUMO

Sarcina ventriculi is an anaerobic gram-positive bacterium capable of surviving in the acidic environment of the stomach and causing gastrointestinal symptoms. We report the case of a 51-year-old patient with no notable medical history who presented with abdominal distension, nausea, and vomiting. Initial endoscopic evaluation revealed a distended stomach in stasis with pyloric stenosis. Biopsies revealed the presence of Helicobacter pylori and S. ventriculi. A therapeutic protocol was administered, but no symptomatic relief was observed. Subsequently, the patient was referred to our institution, where computed tomography imaging of the abdomen was performed. The results corroborated a presentation suggestive of a high obstruction attributable to a right anterior para-duodenal internal hernia. Ultimately, surgery was undertaken, ruling out the diagnosis of right para-duodenal internal hernia and resulting in gastroenteric anastomosis with satisfactory improvement in clinical symptoms.

RESUMO

Sarcina Ventriculi is a gram-positive anaerobic coccus rarely reported in patients with delayed gastric emptying, emphysematous gastritis, gastric ulcers, and perforation. So far, less than 30 cases of sarcina isolated from the stomach have been reported. Herein, we describe a case of a 66-year-old male with a history of persistent epigastric pain and regurgitation. The upper gastrointestinal (GI) endoscopy revealed gastric erythema, edema, ulceration, and food bezoar. A gastric biopsy was done to rule out lymphoma. On histopathological examination, sarcina Ventriculi was identified. This organism is likely to get underreported as it may not be that obvious on routinely stained biopsies. Given its association with life-threatening illness such as emphysematous gastritis and perforation, awareness of this organism is important. It's presence in gastric biopsies must be mentioned in the report and should prompt the clinicians to investigate further for functional causes of delayed gastric emptying and gastric outlet obstruction like occult malignancy.

RESUMO

We report a case of a 64-year-old Jehovah's Witness male, who was post-operative day five of laparoscopic cholecystectomy. He presented with anemia, severe ischemic gastritis, and pneumatosis seen on CT with intravenous contrast. A subsequent upper endoscopy revealed patchy gastric ulceration with bleeding but no overt evidence of perforation. Biopsies were taken, and immunohistological staining identified Sarcina ventriculi. The patient was treated non-operatively with fluconazole and piperacillin-tazobactam for the infection and with sucralfate tablets and pantoprazole injections for ulcer treatment. After five days, a repeat CT scan revealed a resolved pneumatosis. S. ventriculi is a rare bacterium that is increasingly being reported as a cause of emphysematous gastritis with potentially fatal perforation. Surgical intervention should be reserved for unstable patients with perforations and significant, overt bleeding. In this case, non-operative treatment with antibiotics and proton pump inhibitor (PPI) medications were preferred in the setting of anemia in a Jehovah's Witness patient without perforation. The patient showed clinical and radiologic improvement. Further understanding of the role of surgical intervention versus non-operative management is needed for this rare and potentially life-threatening organism.

RESUMO

Acute massive gastric dilatation is a rare condition mainly seen in patients with alimentary disorders. This massive distention may cause gastric necrosis and even perforation and emphysematous gastritis. We report the case of an 18-year-old female with intense abdominal pain and signs of sepsis. Computed-tomography scan diagnosed an acute massive gastric distention within gas into the gastric wall. Despite rapid instauration of conservative treatment, the patient finally underwent surgery. It is important to discard this infrequent pathology even in young and healthy people. An early diagnosis is crucial, a rapid instauration of conservative management may be effective and avoid surgery.


La distensión gástrica masiva es una condición rara, principalmente descrita en pacientes con trastornos de la conducta alimentaria, que puede evolucionar hacia una necrosis, perforación o gastritis enfisematosa. Reportamos el caso de una paciente de 18 años valorada por intenso dolor abdominal y sepsis, diagnosticada de distensión gástrica masiva. A pesar del tratamiento conservador, la paciente requirió cirugía urgente. Es importante descartar esta entidad cuando valoramos a un paciente en Urgencias ya que es una patología infrecuente presente en gente joven y sana. Un diagnóstico temprano es crucial porque el tratamiento conservador precoz puede ser eficaz y evitar la cirugía.

RESUMO

We present a case of a rare cause of gastric perforation and pneumoperitoneum, associated with Sarcina ventriculi. An 88-year-old male presented to the emergency room with significant abdominal pain as his chief complaint. Abdominal radiograph showed extensive free intraperitoneal gas under the diaphragms. Computed tomography (CT) of the abdomen and pelvis showed pneumatosis, portal venous gas, and extensive free intraperitoneal gas with free fluid. Immediate surgical intervention ensued. The gastric biopsies obtained proved valuable for confirming the diagnosis of S. ventriculi. In conjunction with surgery, the patient received a course of antibiotics for a cure.

RESUMO

OBJECTIVES: This study is aimed to report a case of SV-related gastritis and the results of a systematic literature review of SV infections. METHODS: Following a case presentation, we systematically searched different databases (MEDLINE, PubMed, Scopus, Web of Science, EMBASE, google scholar) for the items "sarcina," "ventriculi," "clostridium" with AND/OR. RESULTS: A total of 55 articles reporting 65 cases of Sarcina Ventriculi were found. Thus, 66 patients, including our case, were reviewed. The median age was 51 years (IQR: 0-87 years). Females accounted for 51% of cases. 68% of patients had one or more comorbidities. SV was isolated in the gastrointestinal tract (88%), respiratory (5%), urine (4%), and bloodstream (3%) systems. Upper endoscopy was performed in 52 patients (79%). Biopsies were obtained in all 52 cases and were normal in 23%. Surgery was warranted in 15 patients (23%), and specific antimicrobial therapy was delivered in 34 (52%) patients. Mortality was 14%. At follow-up, 88% of patients showed complete eradication of the SV infection. CONCLUSIONS: Upper gastrointestinal biopsy positive for SV should prompt an evaluation of the clinical conditions, considering the risk of gastric perforation is not negligible. Antibiotic therapy may eradicate the infection and prevent complications. Emergency surgery is required in case of source control.

RESUMO

Clostridium ventriculi (syn. Sarcina ventriculi) is a Gram-positive opportunistic pathogen with sarcina morphology. In the case of gastrointestinal disorders, the treatment is often empirical. Due to the common occurrence in primates and the potential risk of dysbiosis; the antibiotic susceptibility screening of C. ventriculi strains isolated from guenon monkeys and crested gibbons to 58 antibiotics was performed to reduce potentially ineffective antibiotic use in case of disease. Isolates were found to be susceptible to the majority of the tested antibiotics, mainly to (fluoro)quinolones, macrolides, penicillins, and tetracyclines. The susceptibility profiles were similar despite the hosts. Tested strains showed also natural resistance to a few antibiotics on the genus level. Detected in vitro antibiotic efficiency is consistent with documented human treatment cases.

RESUMO

Here we describe a case of a 15-year-old child with Rett syndrome who presented with extreme gastric distension and fatal perforation in the setting of long-standing aerophagia and pathologic colonization with Sarcina ventriculi, a rare bacteria implicated in gastric perforation. This is the first report of gastric perforation associated with colonization by Sarcina in a patient with pathologic aerophagia. Gastric colonization with Sarcina should be considered in intellectually disabled children with pathologic air swallowing who present with severe gastric dilation and/or perforation.

RESUMO

In 1842, when John Goodsir was Conservator to the Museum of the RCSEd, he saw a 19-year-old male patient who vomited a large volume of acidic, fermented-smelling, watery fluid every morning. Under his microscope, Goodsir found the vomitus to be populated with a micro-organism he named Sarcina ventriculi, which he considered to be causative. In so-doing, Goodsir became one of the first people to link a specific micro-organism with a disease. Goodsir recommended small doses of creosote as an antiseptic and claimed that the boy was eventually cured of the vomiting condition. In August of 1863 Charles Darwin was hugely celebrated by the scientific community and the public, but he had suffered from severe stomach problems all his adult life and at this point, he was vomiting daily. He read Goodsir's paper and contacted him and asked if he could send some vomitus samples to Edinburgh in the hope that Goodsir might find Sarcina in it and solve the mystery of his debilitating stomach symptoms and perhaps cure them with creosote. Goodsir examined samples in his microscope, but failed to find Sarcina. Sadly, Darwin went on to suffer constantly from severe stomach problems, recently attributed to lactose intolerance, until he died in 1882, some 20 years later.

RESUMO

Sarcina ventriculi is an extremely rare pathogen. These gram-positive cocci bacteria are rarely identified in gastric biopsies and usually described in the scientific literature as an incidental finding, particularly in patients with delayed gastric emptying, gastroparesis, emphysematous gastritis or gastric perforation. It occurs most commonly in adult women and can be identified easily by its distinctive morphologic features, such as basophilic staining, cuboidal shape, tetrad arrangement, red blood cell-sized packets, flattened cell walls, and refractile nature in bright field microscopy. Although the pathogenesis of the microorganism is highly debated in humans, this bacterium is a well-known pathogen in livestock. Fewer than 30 cases of human infection have been described in the scientific literature so far, but none mentioned this micro-organism as a potential cause of death. We report the case of a 76-year-old patient with gastric perforation due to massive infection with Sarcina ventriculi. To date, this is the first report of human infection with Sarcina ventriculi in Romania.

RESUMO

Emphysematous gastritis is a rare and lethal gastrointestinal emergency if not promptly identified and managed. In rare cases, emphysematous gastritis is associated with Sarcina ventriculi infection, usually in patients with delayed gastric emptying. Here we report a lethal case of S. ventriculi-associated emphysematous gastritis in the absence of delayed gastric emptying in which the diagnosis was confirmed postmortem. This case provides an opportunity to review the clinical presentation, pathophysiology, and management of emphysematous gastritis so that the condition can be promptly diagnosed and managed to prevent significant morbidity and mortality.

RESUMO

Clostridium ventriculi (formerly Sarcina ventriculi) is a Gram-positive, obligate anaerobic coccus. Human infections due to this bacterium have rarely been reported, its involvement in the development of gastric ulcers and perforation has been suggested. We present a case of bacteremia due to C. ventriculi following acute colonic pseudo-obstruction.
