Splenic abscess after appendicitis

We report an appendicitis complicated by a splenic abscess in a patient with polycystic kidneys and multiple cystic lesions in the liver. Clinical decision making for operative intervention was made difficult by the extensive intra-abdominal abnormalities seen on computer tomography. Finally curation was achieved by splenectomy and appendectomy.     

Recurrent neobladder rupture: conservative management

PurposeTo present a case of recurrent neobladder rupture treated in a conservative fashion. To review the articles on conservative management of cases like this one published from 1985.ResultsNineteen articles have been published since 1985 on spontaneous neobladder rupture, 4 of which describe the possibility of a successful conservative management, provided that the patients are carefully selected.ConclusionsFaced to abdominal pain in patients with neobladder, it is essential to suspect spontaneous perforation and, if possible, to confirm such suspicions by means of cystography or CT. An exploratory laparotomy may be necessary in many instances, sometimes due to lack of a diagnosis and sometimes because the patient’s status rules out any other procedure, but in selected and precisely diagnosed cases a conservative management can be resolvent.     

Recurrent abscess after MammoSite brachytherapy

Recently a new catheter was introduced to facilitate brachytherapy in a lumpectomy cavity. Data are limited on the side effects of high-dose brachytherapy to the lumpectomy cavity with the MammoSite catheter. We present a case of recurrent abscesses over a 7-month period in the lumpectomy cavity after MammoSite brachytherapy.     

Histological analysis of appendices removed during interval appendectomy after conservative management of pediatric patients with acute appendicitis with an inflammatory mass or abscess

Background/purpose

To clarify the role of interval appendectomy (IA) in pediatric patients with acute appendicitis with an appendiceal inflammatory mass or abscess, we histologically analyzed the appendices removed during IA.

Patients and methods

We treated 355 consecutive pediatric patients with acute appendicitis and reviewed the admission charts of patients who started conservative management (CM). The histology of the appendix removed during IA was also examined. The relationships among the clinical features, appendicolith formation at the time of IA and histological findings were analyzed by stepwise regression analyses.

Results

(1) CM was started in 48 patients (13.5 %). Recurrence or a remaining abscess was observed in nine patients (18.8 %). (2) Histopathological changes, particularly foreign body reaction with fibrosis and infiltration of inflammatory cells, were observed in about half of the specimens. (3) In a stepwise regression analysis, the presence of an appendicolith at IA was correlated with an appendicolith at diagnosis, foreign body reaction in the appendix and a decrease in the inflammatory reaction at diagnosis.

Conclusion

More than half the patients had strong histopathological changes in the appendix, suggesting a high possibility of recurrence. The presence of appendicolith formation at IA, which is a risk factor for recurrence, was influenced by the presence of an appendicolith at diagnosis, foreign body reaction in the appendix and the inflammatory status of patients at diagnosis. These clinical findings are indications for IA.     

Intra-abdominal abscess after laparoscopic appendectomy for perforated appendicitis

HYPOTHESIS: The incidence of postoperative intra-abdominal abscess is higher after laparoscopic compared with open appendectomy for perforated appendicitis. METHODS: A historical cohort study of pediatric patients operated on for suspected appendicitis by open appendectomy or laparoscopic appendectomy compares the incidence of postoperative intra-abdominal abscess for each procedure. SETTING: A tertiary care center. PATIENTS: Five hundred thirty-eight pediatric patients were operated on for suspected appendicitis at our institution between 1974 and 1999. Of these, 453 were included in the study. Of the excluded patients, 9 had incomplete medical records, 69 had normal or interval appendectomies, and 7 had appendixes removed by methods other than laparoscopy or right lower quadrant incision. INTERVENTIONS: Open appendectomy performed through a right lower quadrant incision or laparoscopic appendectomy performed through a 3-trocar approach by 1 of 3 pediatric surgeons at our institution. MAIN OUTCOME MEASURE: The incidence of postoperative intra-abdominal abscess after laparoscopic vs open appendectomy. RESULTS: In perforated appendicitis (170 patients), the incidence of postoperative abscess after laparoscopic appendectomy was 24% vs 4.2% after open appendectomy. The relative risk ratio of developing a postoperative abscess after perforated appendicitis was 5.6 (confidence interval, 2.1-16.0) after laparoscopic vs open appendectomy. The results remained significant when controlled for age, sex, intraoperative irrigation, and preoperative antibiotics. Postoperative abscess in all acute, gangrenous, and perforated appendicitis after laparoscopic appendectomy was 6.4% vs 3.0% after open appendectomy. This was not statistically significant. CONCLUSION: There is a significant increase in the incidence of postoperative intra-abdominal abscess with perforated appendicitis after laparoscopic compared with open appendectomy in pediatric patients.     

Recurrent intracranial abscess after a long latency

A case of recurrent intracranial abscess at the initial site after a latency of 16 years is presented. The causes and possible mechanisms of recurrence are discussed.     

Association between Streptococcus milleri and abscess formation after appendicitis

Abscesses after appendicitis occur in some patients despite timely surgery and antibiotics. The Streptococcus milleri group of bacteria are commonly associated with gastrointestinal abscesses. This study investigated the relationship between S. milleri and abscess formation after appendicectomy a total of 301 patients (172 males, 129 females, median age 22 years) with appendicitis were identified retrospectively from the hospital PAS computer system who had an appendicectomy and peritoneal bacteriology swabs taken. All but one patient had prophylactic antibiotics. Patients were divided into three groups according to peritoneal bacteriology: group 1 (S. milleri +/- mixed faecal organisms, n = 61); group 2 (mixed faecal organisms, n = 126); and group 3 (sterile, n = 114). The chi squared and Student t-tests were used for statistical analysis. Thirteen (21%) of group 1 patients developed an intra-abdominal abscess compared with 4 (3%) in group 2 and 2 (1.7%) in group 3 (P < 0.0001). There was no difference in the prevalence of gangrenous or perforated appendicitis between groups 1 and 2 (56% versus 52%) but these worse forms of appendicitis were less common in group 3 (22%). Group 1 patients had a mean total hospital stay of 10 days versus 6 days for group 2 and 4 days for group 3 (P < 0.001). S. milleri was associated with a 7-fold increase in abscess formation after appendicectomy and a longer hospital stay. Antibiotic prophylaxis did not prevent this complication.     

Local recurrence after gastrectomy for cancer. Presentation of 2 clinical cases]

The Authors report two cases with local recurrence after partial gastrectomy for advanced gastric carcinoma. The Authors suggest that chemo and/or radiotherapy associated with surgical treatment can improve the prognosis in some patients with recurrence. Response to chemotherapy and time elapsing before recurrence appears may select this group of patients.     

Prostatic abscess. Apropos of 2 cases

Prostatic abscess in an acute inflammatory condition in which clinical diagnosis is not always easy. Ultrasound is of considerable help in diagnosis of this prostatic pathology. We report two cases. The first patient was treated by trans-rectal drainage. The second was treated with success by percutaneous drainage. The clinical, diagnostic and therapeutic aspects of this rare pathology are discussed.

Early appendectomy vs. conservative management in complicated acute appendicitis in children: A meta-analysis

BackgroundNo consensus exists among surgeons regarding the optimal treatment of complicated acute appendicitis in children (CAA). Existing studies present heterogeneity of data and only few studies analyzed free perforated appendicitis (FPA) separately from appendicular abscess (AAb) and appendicular phlegmon (AP).MethodStudies which have been judged eligible for this systematic review and consequent meta-analysis are those comparing non-operative management (NOM) with operative management (OM) in children with CAA. Studies were subgrouped between those analyzing mixed patients with CAA, those focusing on patients with AAb/AP and those focusing on patients with FPA.ResultsFourteen studies fulfilled the inclusion criteria and were included in the meta-analysis with a total of 1288 patients. In the fixed-effects model the complication rate was significantly favorable to the initial NOM arm for the AAb/AP subgroup (RR = 0.07, 95%CI = 0.02–0.27) and to the OM arm for the FPA subgroup (RR = 1.86, 95%CI = 1.20–2.87); the re-admission rate was significantly favorable to the initial NOM arm for the AAb/AP subgroup (RR = 0.35, 95%CI = 0.13–0.93) and to the OM arm for the FPA subgroup (RR = 1.49, 95%CI = 1.49–7.44). There was no statistical heterogeneity for the two subgroups of patients. The costs weren't significantly different between NOM and OM. The length of stay was favorable to OM. The pooled proportion rate of NOM success was 90%, the pooled relapse rate of appendicitis was 15.4%.ConclusionsChildren with AAb/AP reported better results in terms of complication rate and re-admission rate if treated with NOM. Conversely children with FPA showed lower complication rate and re-admission rate if treated with OM.Level of evidenceII
