Hepatic abscess secondary to a rosemary twig migrating from the stomach into the liver

The ingestion of a foreign body that penetrates the gastric wall and migrates to the liver, where it causes an abscess is uncommon. A case of an ingested rosemary twig perforating the gastric antrum, then migrating to the liver, complicated by hepatic abscess and Staphylococcus aureus sepsis is reported. A 59-year-old man without a history of foreign body ingestion was admitted to our hospital because of sepsis and epigastralgia, which had progressively worsened. No foreign body was identified at preoperative imaging, but a rosemary twig was discovered during laparotomy. The liver abscess and sepsis were controlled successfully with surgery and antibiotics. This unusual condition should be kept in mind when dealing with cases of hepatic abscess, or even sepsis of unknown origin. Despite the improvement of non-surgical techniques such as percutaneous drainage and interventional endoscopy, surgery still remains important in the treatment of hepatic abscess caused by an ingested foreign body.     

Liver abscess caused by an unnoticed swallowed toothpick perforating the colonic wall

We present an unusual case of a liver abscess caused by a swallowed toothpick in a 43-year-old man. The abscess was first punctured under percutaneous ultrasound control and intraveneous administration of antibiotics whereas the diagnosis of the foreign body stuck in the sigmoid bowel wall was only made by a follow-up computed tomography since the patient had no complains indicating a colonic pathology. Even more, the patient did not remember ever having ingested a foreign body. The wooden toothpick was then successfully removed by endoscopy. The case report stresses the need for a search of the cause of unexplained liver abscesses and highlights the importance of computed tomography as the first imaging technique as the foreign body was missed on the ultrasound examination. Finally, the non-surgical treatment as first line management of liver abscesses will be discussed.     

Liver abscesses associated with stromal tumour of the stomach in a young woman.

A 23-year-old Japanese woman was admitted to hospital because of pyrexia and anaemia. She was found to have liver abscesses and a gastric submucosal mass by computed tomography and ultrasonography. Gastroscopy and a barium swallow revealed a round submucosal mass with a giant ulceration in the body of the stomach. The liver abscesses were successfully treated by percutaneous transhepatic drainage and intravenous administration of antibiotics. Cultures of the fluid from a liver abscess and gastric juice yielded alpha-haemolytic streptococci. Three weeks after the drainage, partial gastrectomy was performed. The tumour was diagnosed as a stromal tumour of the stomach (leiomyosarcoma) in the final histological report. The patient was discharged on postoperative day 17 without receiving adjuvant radio-chemotherapy. There have been no signs of recurrence two years after surgery. This is a rare case of a liver abscess associated with a stromal tumour of the stomach in a young patient. The bacteriological examinations suggested a possible association between these diseases.     

A case of amoebic liver abscess complicated by a gastric fistula cured with oral medication only

A 26-year-old man was admitted to our hospital because of a high-grade fever and abdominal pain. A blood test showed marked inflammation. Enhanced computed tomography (CT) showed an 8.0×6.0cm cystic lesion in the left hepatic lobe. Esophagogastroduodenoscopy showed a huge egg-yolk-like mass in the gastric submucosa in the lesser curvature of the gastric body from the gastric angle. There were 3 ulcers on the mass, out of which milky pus flowed. Trophozoites of Entamoeba histolytica were detected from cultures of the liver abscess and a biopsy of the gastric ulcers. The amoebic dysentery antibody titer was increased 1600 times. An amoebic liver abscess complicated by a gastric fistula was diagnosed. As therapy, oral metronidazole was administered for 2 weeks without percutaneous drainage. The systemic inflammatory findings improved immediately and the abscess decreased markedly in size.     

Medical vs surgical management of spinal epidural abscess

BACKGROUND: We compared the clinical features and outcomes of patients with spinal epidural abscess treated with prolonged parenteral antibiotics alone or combined with computed tomography-guided percutaneous needle aspiration drainage with those of patients undergoing surgical decompression. METHODS: A retrospective analysis of 57 cases of spinal epidural abscess treated at an academic teaching hospital during a 14-year period. RESULTS: The lumbar region was most frequently involved, and 46% of patients were immunocompromised. Staphylococcus aureus was the most frequently encountered pathogen. For 60 treatment courses, management included medical only (25 patients), medical plus computed tomography-guided percutaneous needle aspiration (7 patients), or surgical drainage approaches (28 patients). Prolonged use of parenteral antibiotics alone or combined with percutaneous needle drainage yielded clinical outcomes at least comparable with antibiotics plus surgical intervention, irrespective of patient age, presence of comorbid illness, disease onset, neurologic abnormality at time of presentation, or abscess size. CONCLUSION: Patients with spinal epidural abscess can be safely and effectively treated with conservative medical treatment without the need for surgery.     

A case of acute phlegmonous gastritis successfully treated with antibiotics

Acute phlegmonous gastritis is a rare disorder in which bacterial infection occurs in the gastric wall. Gastrectomy involving the affected area has been thought to be an effective form of treatment. The authors report a case of a 32-year-old woman who had severe upper abdominal pain without signs of peritoneal irritation. Endoscopy showed edematous and reddened gastric mucosa with a mass lesion in the gastric antrum. Endoscopic ultrasonography showed thickening of the antral wall and a low-echoic mass in the gastric antrum, thought to represent a fluid collection. White pus was aspirated from the mass. Localized type of acute phlegmonous gastritis with a gastric abscess was diagnosed. Culture of the pus showed Streptococcus pneumoniae. Through early diagnosis without laparotomy, the patient's gastritis was successfully treated with antibiotics alone.     

Pyogenic Liver Abscess Secondary to Foreign Body (Fish Bone) Treated by Laparoscopy: A Case Report

Liver abscess due to perforation of the gastrointestinal tract by a foreign body is a rare and possibly fatal event. Diagnosing this pathology is complicated by the lack of specific symptoms and unfamiliarity of ingestion by the patient and low clinical suspicion of this disease. In the case of liver abscess unresponsive to aspiration and administration of antibiotics, this hypothesis must be made, despite its low incidence. This case report describes and illustrates a case of liver abscess secondary to fish bone ingestion with consequent piercing of the lesser gastric curvature, diagnosed by computed tomography and specific anamnesis. Laparoscopy was performed to extract the foreign body, without complications; the patient is currently asymptomatic and does not present any abnormal physical examination findings. We believe this represents the first case report of a successful laparoscopic treatment in South America for the removal of an ingested foreign body associated with pyogenic liver abscess.     

Gastric penetration by an ingested toothpick successfully managed with computed tomography and endoscopy

A 31-year-old woman who had ingested a toothpick consulted our hospital because of epigastralgia. An abdominal computed tomography (CT) demonstrated a toothpick penetrating the gastric wall. Endoscopic examination demonstrated an ingested toothpick protruding from the prepyloric antrum. The whole toothpick was removed using a basket catheter without complications. CT images were useful to acquire clinical information such as location of the toothpick end. Unintentional ingestion of toothpicks must be considered potentially dangerous. The locations of both ends of the toothpick should be confirmed by CT or ultrasonography; and then, the toothpick should be removed as soon as possible.     

Non-operative management of pyogenic liver abscess

BackgroundLiver abscess is a serious disease traditionally managed by open drainage. The advances in interventional radiology over the last two decades have allowed a change in approach to this condition. We have reviewed our experience in managing liver abscess over the last 7 years.MethodsDetails of all patients admitted with liver abscess between 1995 and 2002 were prospectively entered onto our database. A review was performed to document the use of imaging and drainage techniques. Aetiology, morbidity, mortality and duration of hospital stay were recorded.ResultsForty-two patients (median age 53 [22–85] years; M:F 18:24) were admitted with liver abscess (multiple abscess 20); 19 cases were of portal tract origin, 16 cases were of biliary tract origin and 7 cases were spontaneous. Forty-one patients were managed non-operatively, all received antibiotics (cephalo-sporins 76%, metronidazole 88%, quinolones 33%). Diagnosis was made on ultrasound scan (22) or CT (20). Five patients were managed with antibiotics alone. Fifteen patients were managed initially with percutaneous aspiration and five subsequently required percutaneous drainage. Twenty-one patients had primary percutaneous drainage, nine requiring a further procedure (aspiration 3, drainage 6). One patient underwent hepatic resection. Median hospital stay was 16 (6–35) days. There was one death, but no procedure-related morbidity.DiscussionNon-operative management of solitary and multiple liver abscesses is safe and effective.     

Extraction and clipping repair of a chicken bone penetrating the gastric wall

We report a case of gastric penetration caused by accidental ingestion of a chicken bone in a 42-year old woman with a partially wearing denture. Three days ago, she accidentally swallowed several lumps of poorly-chewed chicken. Physical examination disclosed mild tenderness in the periumbilical area. Abdominal Computed tomography （CT） showed a suspicious penetration or perforation of the stomach wall measuring about 3 cm, by a linear radiopaque material at the lesser curvature of the antrum. The end of a chicken bone was very close to but did not penetrate the liver. Endoscopic examination revealed a chicken bone that penetrated into the prepyloric antrum. The penetrating chicken bone was removed with grasping forceps. Five endoscopic clips were applied immediately at the removal site and the periumbilical pain resolved promptly. After removal of the chicken bone, the patient was treated with conservative care for three days, after which she was completely asymptomatic and discharged without complication. To treat gastric penetration by a foreign body, endoclipping can be a useful method in patients with no signs or symptoms of peritoneal irritation.     

A Case of Penetration of the Large Intestinal Wall by a Toothpick

A 66-year-old man was admitted to hospital with symptoms of acute abdomen. Based on colonoscopic findings, localized peritonitis due to penetration of the sigmoid colon by a toothpick was diagnosed. During colonoscopy, the toothpick was removed using a grasping forceps, meaning that surgery was avoided. In cases where abdominal pain of unknown origin is observed, physicians should proceed with routine medical care while considering the possibility of foreign body ingestion, and work toward an early diagnosis.     

Inflammatory pseudotumor of the liver diagnosed by needle liver biopsy under ultrasonographic tomography guidance

Inflammatory pseudotumor of the liver is a rare benign lesion, but exploratory laparotomy and a hepatectomy are often performed unnecessarily after various misdiagnoses, including liver abscess, hepatocellular carcinoma, metastatic liver tumor, and cholangiocarcinoma. We present a case of hepatic inflammatory pseudotumor in a 17-year-old man in whom diagnosis was confirmed by liver needle biopsy under ultrasonographic tomography (UST) guidance. He had complained of fever and right hypochondralgia 2 months after being operated for appendicitis. He was admitted to our hospital because of the persistence of these symptoms and the presence of a hepatic mass lesion detected by UST. He had hepatomegaly, with tenderness; leukocytosis and elevated erythrocyte sedimentation rate and C-reactive protein level were noted. UST showed a hypoechoic mass in the liver and pre-contrast computerized tomography (CT) revealed a low-density area with an ill defined margin, which was barely enhanced by the contrast medium. On the basis of the patient's clinical symptoms and the laboratory data and imaging studies, the presence of a liver abscess was suspected and antibiotics were administered. One month after the initiation of the antibiotic therapy, UST demonstrated that the portal vein had dilated serpiginously and penetrated into the mass. As the heterogeneous appearance displayed by post-enhanced CT indicated the need for a differential diagnosis of the hepatic mass lesion to rule out hepatocellular carcinoma, percutaneous needle biopsy was performed, under UST guidance. Histopathological examination demonstrated marked infiltration of plasma cells and fibrosis, findings which were consistent with those of hepatic inflammatory pseudotumor. There was a spontaneous reduction of the hepatic pseudotumor without continuous antibiotics and this reduction was documented on follow-up UST and CT.

Clinical and Microbiological Features of Liver Abscess after Transarterial Embolization for Hepatocellular Carcinoma

Objectives: To present the clinical and microbiological features of liver abscess after transarterial embolization (TAE) for hepatocellular carcinoma (HCC). Methods : We retrospectively reviewed records of 452 TAE procedures in 289 patients with HCC over a 2-yr period. Results : Four men and one woman with a mean age of 68.4 yr were diagnosed with liver abscess 1–8 wk (mean 4.6 wk) after the embolization. The incidence was 1.1% (5/452). Common symptoms included fever, chills, and right upper quadrant pain. Serum aminotransferase, alkaline phosphatase, and γ-glutamyltransferase levels and leukocyte count were frequently elevated. All the abscesses appeared as areas of hypodensity on CT scan and hypoechogenicity on ultrasonogram. The areas contained gas in the embolized tumor, which led to the suspicion and finally the diagnosis of abscess. In contrast to predominance of Gram-negative aerobes in sporadic pyogenic liver abscesses, the causative microorganism was predominantly Gram positive (60%). All patients were treated with parenteral antibiotics plus percutaneous aspiration, drainage, or operation, but one patient died from the abscess. Conclusions : For patients receiving TAE for HCC, few specific clinical or radiological features could readily differentiate patients complicated with liver abscess from those without. This may delay a timely diagnosis and lead to significant morbidity. Hence, in patients with risk factors, including old age, previous biliary tract disease, large tumor size (>5 cm), and gas forming in the embolized tumor, aspiration of the suspected focal hepatic lesion should be performed as soon as possible.     

A case of type 2 diabetes with a large abscess of the gastric wall successfully treated with a glycemic control and systemic antibiotics

A case of type 2 diabetic patient, a 67-year-old woman, with a large abscess of the gastric wall which seemed to be a primary lesion is described for the first time. Fortunately, patient was successfully treated with both the maintenance of a good glycemic control and systemic antibiotics without laparotomy or drainage. Thus, a tight glycemic control and awareness of this disease should be reemphasized, and this may improve the prognosis of this rare and fatal one, even a poorly-controlled diabetes.     

Liver abscess formation after transarterial chemoembolization for malignant hepatic tumor

BACKGROUND/AIMS: To study and review the clinical manifestations, microbiology, comorbidity, and diagnosis of liver abscess after transarterial chemoembolization for malignant hepatic tumor. METHODOLOGY: We retrospectively reviewed 1374 patients who underwent 2581 transarterial chemoembolization procedures due to malignant hepatic tumors over an 8-year period. RESULTS: 7 patients had liver abscess after transarterial chemoembolization. The incidence was 0.27% (7/2581). Hepatocellular carcinoma was diagnosed in all 7 patients, whose liver function was classified as stage A by the Child-Pugh criteria. The clinical manifestations were intermittent fever, abdominal pain, and leukocystosis. All the patients had hyperechoic spots with reverberative shadows on sonograms or low attenuation areas with different Hounsfield units on computed tomography scan, which expressed the 100% incidence (7 of 7) of gas-forming abscesses. Percutaneous drainage or aspiration was done in 6 patients. One received laparotomy with local debridement due to suspicious organ rupture. The pus culture showed Gram-negative bacteria in all patients. Blood cultures were positive in only 3 of 7 patients (43%). No patients died of liver abscess after aspiration, drainage, or debridement of abscess combined with parenteral antibiotic treatment. Biliary tract diseases, found in 4 patients, were the most common comorbidity. CONCLUSIONS: Liver abscess after transarterial chemoembolization is a very rare complication, which usually develops in patients with biliary tract disease. Gram-negative bacteria are the main pathogens. The incidence of gas formation is higher after transarterial chemoembolization than in the general population. However, the prognosis is good after adequate clearance of pus and antibiotic treatment.     

Cryptogenic hepatic abscesses--their management in a non-specialist centre

Twelve patients with cryptogenic hepatic abscess were admitted to hospital in Nottingham between 1977 and 1984. Two patients died and those that recovered were variously treated with open surgical drainage, aspiration and antibiotics.     

Hepatic abscess induced by foreign body： Case report and literature review

Hepatic abscess due to perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon. Pre-operative diagnosis is difficult as patients are often unaware of the foreign body ingestion and symptoms and imagiology are usually non-specific. The authors report a case of 62-year-old woman who was admitted with fever and abdominal pain. Further investigation revealed hepatic abscess, without resolution despite antibiotic therapy. A liver abscess resulting from perforation and intra-hepatic migration of a bone coming from the pilorum was diagnosed by surgery. The literature concerning foreign body-induced perforation of the gastrointestinal tract complicated by liver abscess is reviewed.     

Single and multiple pyogenic liver abscesses. Natural history, diagnosis and treatment, with emphasis on percutaneous drainage

The presenting features, modes of treatment and clinical course were reviewed for 55 patients with pyogenic liver abscess, seen at Duke University Medical Center over a 15-year period. Thirty-three patients had a solitary abscess and 22 had multiple abscesses. Most patients were between the ages of 40 and 60 years. Males predominated, 2.4:1. Major underlying conditions included biliary tract disease, malignancy and colonic disease. Eight patients, each with a solitary abscess, had no identifiable underlying condition. Symptoms and signs were nonspecific: fever, chills, focal abdominal tenderness and hepatomegaly were common. A raised serum alkaline phosphatase level was the most consistent abnormal laboratory finding. CT with contrast enhancement, radioisotope scanning and ultrasonography all accurately defined solitary hepatic abscesses. However, CT scan was more successful than other imaging techniques in detecting multiple abscesses. In seven patients the diagnosis was made only at laparotomy. Overall, a diagnosis of liver abscess was made in 50 living patients (91%). Microorganisms were recovered from pus and/or blood cultures of 44 patients (80%). Most common were enteric gram-negative facultative rods, anaerobic gram-negative rods, and microaerophilic streptococci. Single abscesses were more likely than multiple abscesses to contain more than one organism. All patients received antibiotics; the choice of antibiotic does not appear to be critical provided the regimen has a broad spectrum including activity against anaerobes. Surgical or percutaneous drainage was successful when attempted in all patients with a single abscess, but the outcome was less favorable in those with multiple abscesses. Percutaneous drainage is currently replacing open operative drainage as the method of choice. Overall mortality in patients with single abscesses was 15% (5/33) and in those with multiple abscesses 41% (9/22).     

A case of secondary gastric wall abscess due to perforation from advanced colonic cancer successfully treated by endoscopic endoprostesis using endoscopic retrograde biliary drainage tube]

A 44 year-old man was admitted to our hospital because of severe left upper abdominal pain and high fever. Blood examinations revealed high levels of white blood cell count and CRP. An abdominal enhanced CT scan showed a low-density mass with an enhanced margin at the posterior side of the gastric body, and an irregular mass nearby at the transverse colon. We diagnosed a gastric wall abscess due to perforation from advanced colonic cancer and performed endoscopic drainage and endoprostesis by ERBD tube insertion into the abscess through the gastric wall. After the procedure, the clinical symptoms and laboratory data improved quickly, and we could continue further examinations and proceed safety with the treatment plan. To our knowledge, this is the first reported case of a gastric wall abscess due to penetration by gastrointestinal tract cancer which was treated with endoscopic endoprostesis.     

Endoscopic transgastric drainage of a gastric wall abscess after endoscopic submucosal dissection

A 63-year-old woman was referred to our hospital for further examination because of an incidental finding of early gastric cancer.Endoscopic submucosal dissection(ESD)was successfully performed for complete resection of the tumor.On the first post-ESD day,the patient suddenly complained of abdominal pain after an episode of vomiting.Abdominal computed tomography(CT)showed delayed perforation after ESD.The patient was conservatively treated with an intravenous proton pump inhibitor and antibiotics.On the fifth post-ESD day,CT revealed a gastric wall abscess in the gastric body.Gastroscopy revealed a gastric fistula at the edge of the post-ESD ulcer,and pus was found flowing into the stomach.An intradrainage stent and an extradrainage nasocystic catheter were successfully inserted into the abscess for endoscopic transgastric drainage.After the procedure,the clinical symptoms and laboratory test results improved quickly.Two months later,a follow-up CT scan showed no collection of pus.Consequently,the intradrainage stent was removed.Although the gastric wall abscess recurred 2 wk after stent removal,it recovered soon after endoscopic transgastric drainage.Finally,after stent removal and oral antibiotic treatment for 1 mo,no recurrence of the gastric wall abscess was found.
