ObjectiveTo analyze the clinical features of Legionella-associated cavitary pneumonia, and to explore the diagnosis, treatment planning, and clinical management of patients.MethodsThe data of a patient with severe Legionella-associated cavitary pneumonia were collected and analyzed. Databases including PubMed, Ovid, Wanfang, VIP and Chinese National Knowledge Infrastructure were searched for pertinent literatures, using the keyword "Legionella, lung abscess or cavitary pneumonia" in Chinese and English from Jan. 1990 to Jun. 2019. The related literature was reviewed.ResultsA 60-year-old male patient was admitted to hospital because of fever, cough, and expectoration for five days. On presentation, his temperature was 38.3 °C, and pulmonary auscultation revealed rales on the left side of the lungs. Culture of lower airway secretions obtained by bronchoscopy revealed Legionella pneumophila infection, and serotype 6. Chest computerized tomography showed a consolidation in the left lung and an abscess in the left upper lobe. The patient was discharged from the hospital after three months of anti-Legionella treatment (Mosfloxacin, Azithromycin, etc.). Fifteen manuscripts, including 18 cases, were retrieved from databases. With the addition of our case, a total of 19 cases were analyzed in detail. There were 15 males and four females, aged from 4 months to 73 years old. Most of them (14/19, 73.7%) were accompanied by multiple underlying diseases. Initial empiric antimicrobial therapy failed in 15 (78.9%) cases, and 7 (36.8%) patients required combination therapy. The courses of antimicrobial treatment were from 3 to 49 weeks. All except one patient were fully recovered and discharged from hospital.ConclusionsLegionella pneumonia with pulmonary abscess or cavity is rare and often presents with fever. Pulmonary imaging shows infiltration in the initial, but can be free of cavities or abscesses. Most patients have basic diseases. Severe patients often need to be treated in combination with antibiotics for long periods of time.
Objective To investigate the early diagnosis and effective treatment of Fournier syndrome. Methods The clinical data of 385 patients with perianal abscess in this hospital between 2006 and 2009 were retrospectively analyzed for screening the patients with complication of Fournier syndrome. Results Fournier syndrome was detected in 6 patients （1.56%）， who were all cured by treating with early incision and drainage, complete debridement, effective antibiotics, and supporting therapy. Conclusions Perianal abscess can induce Fournier syndrome of perineal, genital, and abdominal wall regions, which spreads rapidly and progressively, so early diagnosis and extensive surgical debridement play a decisive role on the prognosis.
Rupture is one of main complications of liver abscess. Seventy-seven patients with rupture of liver abscess are reviewed. Liver abscess may freely rupture into adjacent structures or organs or serous cavities and cause vatious complications. The causative factors of rupture of liver abscess in this series were late medical consultation in the course of the disease, delayed treatment due to misdiagnosis, and improper treatment. Measures that prevent rupture of liver abscess include raising clinical awareness of early diagnosis and timely effective drainage. The authors consider that transperitoneal surgical drainage is the best approach. Most patients with rupture of liver abscess should be treated by surgical drainage togather with transomental or transumbilital veno-catheterization for antibiotic infusion. Patients with rupture of liver abscess usually present a poor prognosis and a high mortality rate. The mortality in this group was 35.1%(27/77), which is closely related to the complications of the rupture of liver abscess.

Objective To expand the utilization of minimally invasive technologies for parapancreatic abscess, and summarize the application experience of choledochoscope for treatment of parapancreatic abscess. Methods The clinical data and treatment effectiveness of 36 patients with parapancreatic abscess from Dec. 2000 to Dec. 2008 were analyzed retrospectively. These patients had experienced percutaneous puncture and been placed drainage tube under the ultrasound guidance first, then expanded the sinus tract gradually, and performed debridement by choledochoscope. The flexibility of choledochoscope was used to remove the necrotic tissue and pyogenic membrane repeatedly by clamping, netting and vacuum aspiration in every domain. Results Thirty-six patients were performed percutaneous puncture and placed drainage tube, 3 cases were given canalis singularis, 7 cases were double tube, 26 cases were over three tube. The debridement times were 3-14 by choledochoscope, average 5.6 times. There were 6 cases with improving systemic symptoms, blood routine and temperature recovering normal, and drink and food recovering, then discharged from hospital with tube after 1-2 times of debridement. Length of stay was 25-132 d, average 76 d. The curing rate was 91.7% (33/36). Two cases were turned into open surgery because of broad necrotic tissue range combined with many abdominal cavity abscess with good postoperative recovery and cured. One case was dead of severe multiple organ failure combination. There were 2 patients with hemorrhage, 3 patients with external intestinal fistula. Conclusions The debridement of choledochoscope for parapancreatic abscess treatment is a simple, flexible and effective method. It changes the viewpoint that parapancreatic abscess can be cured only by operation drainage, decreases the patients’ trauma and accomplishes the idea of damage control by minimally invasive technologies.
Objective To review and evaluate the global clinical research literatures about the surgical management for prostatic abscess in the past decade, so as to provide useful information for clinical practice. Methods Based on the principles of evidence-based medicine, and the methods of bibliometrics, the PubMed database was searched from January 1st 2000 to April 10th 2011. The literatures about prostatic abscess were screened according to the predefined inclusion and exclusion criteria, the quality was assessed, the valid data were extracted and then systematical evaluation was performed after the establishment of the database with OpenOffice.org 3.8 Calc. Results a) A total of 205 articles were found initially and 81 were finally included with the total 388 cases involved (on average, 4.79 cases per paper). The patients’ ages ranged from 10 days to 83 years old. Two studies were diagnostic tests, and all the other 79 were surgical intervention studies; b) There was no controlled clinical trail. A total of 16 studies involving more than 5 cases for each and 311 cases in all which were retrospective case analyses, all the other 65 were individual case reports; c) American scholars published 13 papers (16.5%), ranked as the first. American and European scientists published 36 papers (44.44%). Chinese scholars published quite fewer studies, of which only 2 were in English; d) The incidence increased in younger patients gradually. The pathogens included fungi and bacteria. Most bacteria were gram-positive cocci (such as Staphylococci), followed by gram-negative bacillus (such as Klebsiella). There were also some minority pathogens. The pathogens were complex and quite diverse in different districts. The predisposing factors included both regional and systematic conditions, with diabetes mellitus, hepatocirrhosis, manipulations of lower urinary tract and urinary tract infections as the common; e) The diagnostic procedures included evaluation on symptoms and signs, physical examination, identification of pathogens, and medical imaging examinations (TRUS, CT, MRI). The therapeutic options included routine managements, conservative antibiotic therapies and surgical drainages. The surgical routes were transcutaneous, transperineal, transrectal, and transurethral. The fine needle aspiration, indwelling catheter drainage, or incision and drainage were performed under the guidance of TRUS, EUS or CT through transperineal or transrectal routes. The TUR, TURP or TUIP drainages were performed through transurethral route. The failed cases of fine needle aspiration were then treated by transurethral or transperineal incision and drainages, and some patients were also treated by urinary diversion; f) The best surgical method could not be concluded for lack of controlled data; and g) Few cases died from severe complications, and the outcomes of the majority cases were good. Conclusion a) The literatures about prostatic abscess are abundant but of low quality, with all retrospective studies or individual case reports, and most are published by American and European scholars; b) The prostatic abscess affects all ages but tends to increase in the young. Most pathogens are the gram-positive cocci (such as Staphylococci) ranked as the top and followed by gram-negative bacillus (such as Klebsiella), and the pathogens are obviously diverse in different districts; c) The predisposing factors are commonly seen as diabetes mellitus, hepatocirrhosis, manipulations of lower urinary tract and urinary tract infections; ......
ObjectiveTo evaluate the clinical effect of ultrasound guided puncture irrigation and traditional incision and drainage in the treatment of breast abscess. MethodsCNKI, Wanfang Database, CBM, PubMed, Cochrane Library, Web of Science, and EMbase were searched, at the same time complementary with other retrieval in any language to collect the randomized controlled trials (RCTs) about comparison ultrasound guided needle aspiration with incision and drainage to treat the breast abscesses published by late August, 2015. Data related to clinical outcomes were extracted by two reviewers independently. Statistical analyses were carried out using RevMan5.3 software. ResultsEight studies were included, which involving 373 participants according to the inclusion criteria. The differences were statistically significant about the cure rate [OR=2.51, 95% CI (1.47, 4.28), P=0.000 8〕, effective rate [OR=7.45, 95% CI (2.29, 24.27), P=0.000 9〕, the heeling time [SMD=-1.77, 95%CI (-2.09, -1.44), P < 0.000 01〕, the length of the scar [MD=-2.88, 95% CI (-3.43, -2.33), P < 0.000 01〕, and the complications [OR=0.18, 95% CI (0.05, 0.62), P=0.007〕. Conciusions Compared with traditional methods of incision and drainage, ultrasound guided needle aspiration and wash has the more cure rate, the more effective rate, the less heeling time and scars as well as complications.
