Appendicitis with psoas abscess successfully treated by laparoscopic surgery

Although acute appendicitis is a common disease, retroperitoneal abscesses are rarely observed. Here, we report a case consisting of a psoas abscess and cutaneous fistula caused by appendicitis. The patient was a 56-year-old male who was introduced to our institution due to an intractable right psoas abscess. Imaging tests had been performed over the previous 3 years; however, clinicians could not find the origin of the abscess and failed to resolve the problem. A successful operation was performed via a laparoscopic approach, and 17 mo have passed without recurrence. The advantage of laparoscopic surgery is well understood in cases of appendicitis with abscesses. However, the indication for laparoscopic approach is not clear for retroperitoneal abscesses. From our experience, we can conclude that appendicitis with retroperitoneal abscesses can be managed and treated using a laparoscopic approach.     

CASE REPORT: Spontaneous Gas-Forming Liver Abscess Caused by Salmonella Within Hepatocellular Carcinoma: A Case Report and Review of the Literature

In conclusion, pyogenic liver abscess in hepatocellular carcinoma is unusual. Most of the reported cases occurred after a treatment such as transcatheter arterial embolization or percutaneous ultrasound-guided ethanol injection. Salomonella very rarely causes pyogenic liver abscesses. Only 14 cases have been reported in the English literature since 1911. Salmonella liver abscess occurring within a primary neoplasm is even rarer. There were only two such cases described in patients with hepatocellular carcinoma before. The present case is the third one, but it may be the first case of obvious spontaneous gas-forming liver abscess caused by Salmonella within hepatocellular carcinoma.     

Anterior ilioinguinal incision for drainage of high-located perianal abscess

Most perianal abscesses originate from infected anal glands at the base of the anal crypts. Most abscesses below are usually drained through perianal incision and can be treated successfully. However, when perianal abscesses extend to the high intrapelvic cavity, it may be inadequate treatment through a single route incision through a perianal approach. The aim of this technical note is to show that combined anterior ilioinguinal and perianal incisions may provide optimal surgical field and multiple drainages. Here, we report a 56-year-old male patient with perianal-originating parapsoas abscesses. Residual abscess still remained after initial perianal incision and drainage after 1-month treatment. We presented combined anterior ilioinguinal and perianal incision technique methods for proper drainage in this complicated case. No recurrent or residual abscess remained after 2 weeks of operation. So, combined anterior ilioinguinal incision is feasible for high-located perianal abscess.     

Brain abscess mimicking brain tumor

We review our experience with brain abscesses presenting as primary brain tumor over a 5-year period (1983 to 1988). Four of 66 (6%) patients admitted with the diagnosis of primary brain tumor by computed tomographic scans were found at craniotomy to have brain abscesses. Periapical abscesses found after surgery were determined to be the cause of brain abscess in two of four patients. Our experience suggests that periapical abscess may be a more frequent cause of brain abscess than previously thought, and should be considered before surgery in patients with a suspected brain tumor.     

A case of Salmonella liver abscess]

Liver abscess can be caused by bacterial, parasitic, or fungal infection. Amebic abscesses are more common, but pyogenic abscesses account for three quarters of hepatic abscess in developed countries. Most common pathogens of the pyogenic liver abscess are Escherichia coli, Klebsiella pneumoniae, Bacteroides, Enterococci, Streptococci, and Staphylococci. However, liver abscess caused by Salmonella species has rarely been reported. We experienced a case of Salmonella liver abscess which improved after antibiotic therapy and percutaneous drainage. The patient was 52 years-old man who had an episode of intermittent fever, chills and epigastric pain for 2 weeks. He was diagnosed as liver cirrhosis eight years ago and diabetes three years ago. Salmonella group D, non-typhi was cultured from blood and pus from the liver respectively at the same time. With percutaneous drainage and susceptible antibiotic therapy, liver abscess decreased in size with improvements in fever and abdominal pain.     

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).     

Peliosis hepatis associated with liver and retroperitoneal abscesses

A 33-year-old woman was admitted because of coma and severe shock. CT-scan of the abdomen showed the presence of multiple liver abscesses associated with a retroperitoneal abscess which were drained percutaneously. A liver biopsy showed diffuse peliosis. After resolution of the abscesses the patient's general condition improved and she could be discharged from hospital. Peliosis hepatis is an uncommon disorder characterized by dilated sinusoids with formation of blood lakes. Many pathogenetic mechanisms and causal agents have been proposed. Liver biopsy is necessary to establish diagnosis. By withdrawing the offending drug or treatment of the underlying disorder, regression may be observed.     

Medical and surgical treatment of peritonsillar, retropharyngeal, and parapharyngeal abscesses

Peritonsillar, retropharyngeal, and parapharyngeal abscesses are the most common deep cervical fascial space infections. Most develop secondary to an oropharyngeal or dental infection. Additional factors such as smoking and periodontal disease may also contribute to the formation of a peritonsillar abscess. The CT scan is used to con.rm the presence of deep neck abscesses, but its accuracy has some limitations. Adequate drainage with accompanying antimicrobial therapy and hydration are the cornerstones of management. Catheter or needle drainage of these abscesses may provide an alternative to open procedures and is the drainage method of choice for peritonsillar abscesses. However, in selected cases, medical therapy alone, especially in children, can resolve parapharyngeal and hypopharyngeal abscesses. Ancillary use of steroids reduces morbidity in patients with a peritonsillar abscess and there is a limited but useful place for immediate tonsillectomy in the treatment of this disease.     

Crohn''s Disease of the Colon

Retroperitoneal lumbocrural abscess occurred in 12 patients of 231 with Crohn's colitis or ileocolitis. Although all patients with this complication fell within the group of 175 ileocolitis patients, at least four originated in fistulous tracts of the colon. Eleven of the 12 abscesses developed spontaneously as the first major complication of the disease. The prominent clinical features included pain radiating down the thigh, hip joint flexion, difficulty in walking, hydronephrosis and hydroureter. Internal and external fistulas were significantly more common in the abscess group of 12 patients than in the 219 patients without retroperitoneal abscess. Radiological evidence of granulomatous disease was found in all patients; fistulous tract formation was characteristic and the development of extraperitoneal gas bubbles, in four patients, pathognomonic of abscess with gast-forming organisms. In the presence of established retroperitoneal abscess, the surgical sequence suggested is drainage synchronous with, or followed by diversion and ultimately definitive resection. Resection with anastomosis should not be carried out in the presence of an acute inflammatory process with frank abscess or free pus communicating with the peritoneal cavity. The spontaneous development of retroperitoneal abscess is a serious development in the natural history of Crohn's (ileo) colitis. It frequently heralds the first of a series of operative procedures to deal with the abscess. It sequels are enterocutaneous fistulas and further extension of the disease process.     

Klebsiella pneumoniae-related brain abscess and meningitis in adults: Case report

Introduction:Klebsiella pneumoniae is once thought to be a less common cause of brain abscess in adults and is mainly hospital-acquired. Community-acquired CNS infection (brain abscess and meningitis) caused by K pneumoniae without other metastatic septic abscesses is exceedingly rare. Therefore, we present a rare adult patient with invasive cerebral abscess and meningitis without other invasive abscesses related to K pneumoniae.Patient concerns:A 64-year-old woman experienced a sudden onset of severe continuous headache accompanied by intermittent nausea, vomiting, and fever. Meanwhile, she experienced tinnitus and had a feeling of swelling in the right ear.Diagnosis:Cranial magnetic resonance imaging revealed abnormal hyperintensity signals in the left head of the caudate nucleus. The next generation sequencing of cerebral spinal fluid showed infection with K pneumoniae. The patient was diagnosed with K pneumoniae-related brain abscesses and meningitis.Interventions:Antibacterial treatment was carried out for 2 months.Outcomes:The patient recovered well.Conclusion:Despite the progress of modern neurosurgical techniques, new antibiotics, and modern imaging techniques, brain abscesses are still a potentially fatal infection. Streptococci are common organisms that result in brain abscesses. Nevertheless, Klebsiella species, once thought to be a less common cause of brain abscess in adults, has become an increasingly important cause of brain abscess, especially in Asia.     

Colonoscopic identification of a foreign body causing an hepatic abscess

BACKGROUND: Hepatic abscesses often result from a perforation of the gastrointestinal tract. Although rare, this may occur via puncture by a foreign body. The object may directly extend from the stomach or duodenum into the liver, or rarely, the object may perforate the bowel distal to the duodenum and indirectly extend to the liver leading to the formation of an abscess. CASE REPORT: A 44-year-old man developed an hepatic abscess. Although the abscess was identified on computed tomography, various imaging studies were unable to identify the cause of the infection. After an extended ICU course, the patient was deemed stable enough to undergo a colonoscopy that demonstrated a foreign body penetrating through the wall of the sigmoid colon. CONCLUSIONS: Here we describe the first report of a foreign body leading to a hepatic abscess where the object was identified by colonoscopy. In addition, we present a comprehensive literature review examining the method of identification of gastrointestinal foreign bodies that led to liver abscesses. These findings emphasize that in cases of hepatic abscesses of unknown etiology, direct visualization by colonoscopy may be a useful tool to elucidate the cause of the abscess.     

S3-Leitlinie: Analabszess

Background

Anal abscesses are relatively frequent and most common in young men.

Methods

A systematic review of the literature has been undertaken.

Results

The origin of the abscess is usually the proctodeal gland in the intersphincteric space. There are different types of abscesses: intersphincteric, ischioanal and supralevatory abscesses. Anamnesis and clinical examination are sufficient to indicate surgery. Further examinations such as endosonography or magnetic resonance tomography (MRT) should be considered in recurrent or supralevatory abscesses. The timing of surgical intervention depends on clinical symptoms, whereas the acute abscess is an emergency indication. Surgery is the primary therapy approach for anal abscess. Surgical access (transrectal or perianal) depends on the localization of the abscess. The aim of surgery is to broadly drain the infection and protect anal sphincter structures. The wound should be rinsed regularly (showering with clear water). Treatment with local antiseptics carries the risk of zytotoxicity. Antibiotic treatment is necessary only in selected cases. Any attempt to locate a fistula intraoperatively should be undertaken with great care; proven evidence of a fistula is not mandatory. Although the risk of recurrent abscess or secondary fistula is low, these may be caused by insufficient drainage. The primary fistulotomy of superficial fistulas should only be performed by an experienced surgeon. In the case of ambiguous findings or high fistulas, treatment should be carried out in a second surgical procedure.

Conclusion

For the first time in Germany, this clinical S3 guideline provides instructions for the diagnosis and treatment of anal abscesses based on a systematic review of the literature.     

Endoscopic transpapillary abscess drainage for a patient with giant pyogenic liver abscess

The primary modalities for management of liver abscesses are usually antibiotics and percutaneous drainage. However, in patients with ascites or bleeding tendency, the percutaneous puncture of liver abscesses may be unsuitable. We applied a new approach, nasobiliary tube drainage, for a giant pyogenic liver abscess following diagnostic endoscopic retrograde cholangiopancreatography. Pyogenic liver abscess is often biliary in origin, and this new approach includes assessment of biliary abnormality for the management of the abscess, enabling treatment of parients in whom puncture of the abscess is considered dangerous because of massive ascites around the liver. We propose that this procedure is useful in the management of a subgroup of patients with pyogenic liver abscess. To our knowledge, no previous reports of endoscopic transpapillary abscess drainage in pyogenic liver abscess are available.     

Percutaneous drainage of intra-abdominal abscesses guided by real-time ultrasonography

From October 1982 to October 1984, a percutaneous drainage under realtime ultrasound guidance was performed in 53 patients with abdominal abscesses. The location of the abscesses was subphrenic (23), retroperitoneal (16), and intrahepatic (14). A safe access route was found by using ultrasound and fluoroscopy in 53 out of 55 patients (96 p. 100). Percutaneous drainage failed in 8 patients and 3 of these patients died. The causes of death were: cerebral abscess (1), renal failure after surgery for correction of a duodenal fistula (1), and pancreatic abscess (1). The other five patients were cured by surgical drainage. Two complications were observed: one case each of pneumothorax and purulent peritonitis. Forty-five patients were healed by percutaneous drainage without operation. The duration of the catheter drainage was 14 days +/- 13 (m +/- 1 SD). Our results suggest that percutaneous drainage under realtime ultrasound guidance is an efficient and safe way to treat abdominal abscesses.     

Postneurosurgical Nosocomial Bacterial Brain Abscess in Adults

Abstract Background: Bacterial brain abscess after a neurosurgical procedure has become an important occurrence in the hospital setting. However, no information about the frequency, clinical relevance, and the outcome has been reported. Patients and Methods: Over a period of 19 years (1986– 2004), a total of 31 patients were retrospectively identified as having brain abscesses after neurosurgical procedures and were enrolled in this study. Results: Those included in this study accounted for 0.17% (31/18600) of all neurosurgical procedures in the same period. There was an increased percentage of adult postneurological nosocomial brain abscess compared to all adult bacterial brain abscesses in recent years. The majority of cases were due to Gram-negative bacilli and polymicrobial infections, including both Gram-negative bacilli and Staphylococcus species. Furthermore, the appearance of multi-antibiotic resistant strains was also noted during the study period. The overall fatality rate was 16%. Conclusion: Post-neurosurgical states have become important predisposing factor for bacterial brain abscess. In patients that undergo neurosurgical procedures and develop smoldering fever, progressively disturbed consciousness, headache, and new onset focal neurologic signs, immediate neuro-imaging studies should be undertaken to determine whether bacterial brain abscess is present. Although mortality may be related to the primary brain pathology, early diagnosis and timely use of appropriate antibiotics based on antimicrobial susceptibility testing are also essential for survival.     

Abscesses in Crohn's disease: outcome of medical versus surgical treatment

GOALS: To compare the long-term outcome of medical, percutaneous, and surgical treatment of abdominal and pelvic abscesses complicating Crohn's disease. STUDY: All patients with Crohn's disease and an abdominal abscess treated at one institution during a 10-year period were retrospectively identified. We reviewed hospital and outpatient records and contacted patients for telephone interviews. Outcome measures included abscess recurrence, subsequent surgery for Crohn's disease, and medications used at the time of most recent follow-up. RESULTS: Fifty-one subjects were identified, with a mean follow-up of 3.75 years. Fewer patients developed recurrent abscesses after initial surgical drainage and bowel resection (12%) than patients treated with medical therapy only or percutaneous drainage (56%) (p = 0.016). One half of the patients treated nonoperatively ultimately required surgery, whereas only 12% of those treated with initial surgery required reoperation during the follow-up period (p = 0.010). Most failures of nonoperative therapy occurred within 3 months. Medication use was similar between the treatment groups at the time of most recent follow-up. CONCLUSIONS: In this series, surgical management of abscesses in Crohn's disease was more effective than medical treatment or percutaneous drainage for prevention of abscess recurrence. However, nonoperative therapy prevented subsequent surgery in half of the patients and may be a reasonable treatment option for some patients.     

Incidence of fistulas after drainage of acute anorectal abscesses

PURPOSE: The aim of this study was to assess the incidence of anal fistulas and factors related to this incidence after incision and drainage of acute cryptoglandular anorectal abscesses. METHODS: Of 170 patients without previous anal fistulas, 146 were followed up for an average of 99 (range, 22–187) months after abscess drainage or until a fistula appeared. RESULTS: Fifty-four (37 percent) patients developed a fistula, and 15 (10 percent) patients developed a recurrent abscess. The incidence of fistulas was higher in females than in males (50vs. 31 percent;P=0.0403), especially regarding anterior abscesses (88vs. 33 percent). Abscesses growingEscherichia coli were more prone to fistula formation than those growing other bacteria (46vs. 27 percent;P=0.0368). CONCLUSION: Incision and drainage alone of acute anorectal abscesses is recommended, because an unnecessary primary fistulotomy can be avoided in more than half of the patients by this approach. For superficial anterior abscesses in females, however, primary fistulotomy may be considered.     

Ultrasound diagnosis of retroperitoneal abscesses in spinal tuberculosis

Sixty four patients were examined to elucidate the capacities and accuracy of ultrasonography (USG) in the diagnosis of retroperitoneal abscesses by ultrasound and X-ray studies. They were all operated on. Retroperitoneal abscesses were detected in patients (58 observations). X-ray retroperitoneal abscesses aroused doubts in 23% of cases. Ultrasonographic evidence was erroneous in 4.9% of cases. USG may reveal accumulation or absence of liquid pus, define the extent and number of chambers of retroperitoneal abscesses, which is helpful in answering questions as what surgical access should be chosen and what scope of a surgical intervention made. The safety and cost-effectiveness of the procedure allows a follow-up to be made.     

Liver abscesses secondary to sigmoid diverticulitis: report of four cases

INTRODUCTION: Pyogenic liver abscess often revealed by right sided abdominal pain and fever is a serious and life-threatening pathology. Biliary tract disease is the origin of the abscess in most cases but sometimes remains unidentified. A sigmoid septic source sometimes paucisymptomatic or hidden by an immunosuppressive treatment must be looked for. EXEGESIS: Here are four observations of liver abscesses, which are secondary to unknown sigmoiditis. The etiologic diagnosis was made either by abdomino-pelvic computed tomography or by enema with water-soluble products completed by a coloscopy. Each patient's liver abscesses were emptied by aspiration or catheter drainage in conjunction with antibiotics. Surgical treatment of sigmoiditis was performed either at the same time or later. CONCLUSION: Any liver abscess of unknown origin must lead to a search for unknown or disguised septic sigmoid pathology. Most of the time, injected abdomino-pelvic computed tomography makes the diagnosis possible, but enema associated with coloscopy is sometimes necessary.     

Right adrenal abscess -- an unusual complication of acute apendicitis

Acute appendicitis represents one of the most frequent abdominal emergencies encountered in everyday surgical practice. Local infectious complications are not unusual and retroperitoneal abscesses after acute retrocaecal appendicitis have been previously described. The authors present the case of a 22-years-young female patient, admitted for a right iliac fossa abscess, secondary to gangrenous appendicitis. A right adrenal mass 35/40 mm was revealed during preoperative ultrasound evaluation, which evolved in an adrenal abscess that spontaneously drained 10 days after appendectomy and retrocecal drainage. Adrenal abscesses are exceptionally rare, with only a few cases being reported in the literature, but none of these after acute appendicitis.
