RESUMO
Focal acute bacterial nephritis (lobar nephronia) is a localized bacterial infection of the kidney that has rarely been described in childhood. It is frequently associated to urinary tract anomalies and malformations and its diagnosis is based upon renal ultrasonography and computed tomography. In this article, we report a case in an 8 year old boy admitted to hospital in a septic state.

We report herein the case of a Belgian 76-year-old woman who developed a hepatic tumour suspected to be a breast cancer metastasis. Radiological imaging and guided biopsies were not contributive. The patient underwent an explorative laparoscopy with frozen sections that did not provide further diagnosis, and an open left bisegmentectomy was performed during the same anaesthesia. Histopathological examination of the hepatic mass showed Echinococcus multilocularis metacestodes, demonstrating alveolar echinococcosis. As our patient denied any travel in foreign countries and has undergone regular abdominal ultrasonographies since her mastectomy, it is highly likely that this alveolar echinococcosis had been contracted in Belgium. If some imported cases may be seldom managed in Belgium, to our knowledge, this case is the first occurrence of alveolar echinococcosis contracted in Belgium. This report, added to the demonstration of E. multilocaris infection of 50% of red foxes in Southern Belgium, and the potential infection of domestic cats and dogs, should attract attention of the medical community on the possible outbreak of endemic alveolar echinococcosis in Belgium, and on the related public health concerns.

Focal xanthogranulomatous pyelonephritis is an unusual form of chronic renal infection that is difficult to diagnose prior to surgery. We report on a 19-year-old woman who presented with a renal mass that mimicked malignancy. The diagnosis of focal xanthogranulomatous pyelonephritis was first suspected by radiological findings and further confirmed by histopathologic examination of percutaneous biopsy specimens of the lesion. Successful treatment of the patient was achieved with antibiotic therapy alone. Maximal efforts, including percutaneous renal biopsy, should be made to establish the diagnosis of focal xanthogranulomatous pyelonephritis before a therapeutic decision is reached. We recommend the use of antibiotics as a first-line treatment for patients with focal xanthogranulomatous pyelonephritis.

A direct frontal upper abdominal impact and a bicycle fall in a child are classical mechanisms of blunt pancreatic injury. Clinical symptoms are not characteristic. Serum amylase level is frequently normal at admission and peritoneal lavage fluid amylase is not diagnostic. CT is the most powerful imaging technique to evidence pancreatic contusion and associated injuries but remains normal or doubtful at admission in about 15% of children and 40% of adults. US is sensitive in about 70%. Both modalities are unable to detect pancreatic duct rupture. As ERP cannot be performed in all trauma patients, only patients with minor pancreatic injury can be enrolled in a conservative management without surgical revision. The role of multislice CT at admission and MRP has to be investigated to increase diagnostic efficiency in pancreatic duct injury.

In order to describe the CT findings in pancreatic injury and to evaluate the sensitivity of this technique, we performed a retrospective study. During a 5-year period (1993-1997), eight patients (five males and three females: age range 10-47 years) were investigated with CT. Endoscopicretrograde cholangiopancreatography (ERCP) was obtained in two patients, pre- and intra-operatively, respectively. Among the standard laboratory tests obtained at admission, the value of serum amylase was reviewed. The imaging findings, especially those obtained with CT, were correlated with the surgical findings, when available (in seven of eight patients). At admission, diagnosis of pancreatic injury was missed at CT in three of eight patients (37.5%); thus, the sensitivity of CT for pancreatic injury was 62.5%. ERCP showed rupture of the pancreatic duct in the two cases in which it was performed. Serum amylase was elevated at admission in four of eight patients, resulting in a sensitivity of 50%. After surgery, an enterocutaneous fistula developed in one case, and was managed conservatively. One patient died from brain injury. Proper implementation of the CT technique and accurate film reading is mandatory to establish the diagnosis of pancreatic contusion. No correlation between CT features and type of outcome of surgical management could be established. On retrospective review of the CT examinations, it appeared that two of the three false-negative results could have been avoided. Therefore, proper CT technique and accurate film reading are mandatory in establishing the diagnosis of pancreatic injury.

OBJECTIVE: Functional evaluation of digestive transplants after oesophagectomy for cancer. MATERIAL AND METHODS: We evaluated alimentary comfort and quality of life and performed a videofluoroscopy (radiocinema) in 34 patients who were alive and disease-free one year or more after oesophagectomy for malignancy. There were 22 males and 12 females; mean age was 64 years. Twenty-three patients had a gastric pull-up and 11 a colonic graft. Mean follow-up was 36 months (range: 12-100 months). Possible correlations between clinical symptoms and radiographic observations were studied with Fisher's exact test. RESULTS: Most-cited symptoms were gurgling in 16 patients, early fullness during eating in 15, diarrhea in 14, postprandial sweating in 9, pyrosis in 8, nocturnal cough in 7, and dysphagia in 5. Most patients considered the side effects of the operation as mild to moderate and mean rating of alimentary comfort was 7.6/10. Twenty-five patients qualified their quality of life as good, 8 as satisfactory, and 1 as poor. Twenty-nine patients led active lives. Videofluoroscopic evaluation showed that colonic grafts emptied mainly by gravity, while active contractions were observed in the antrum of gastric transplants. There was a significant correlation between alimentary symptoms and radiographic distension of the transplant. Oro-pharyngeal abnormalities, site of proximal anastomosis, nature, motility, or active versus passive emptying of the transplant did not correlate with clinical complaints. CONCLUSIONS: In most patients quality of life and alimentary comfort are good after oesophagectomy and gastric or colonic interposition. Radiocinema is an adequate method to evaluate the dynamic of the transplant and shows a better emptying of gastric grafts, compared to colonic grafts, particularly when the proximal portion of the oesophagus triggers the progression.

The aim of this study was to describe catheterization techniques and report the results of percutaneous drainage of external pancreatic fistulas. Twenty patients with external pancreatic fistulas in whom medical therapy had failed, were referred for radiologically guided treatment. Fifteen patients had postoperative and five primary fistulas. Sixteen were high-output fistulas (H-OF) and four were low-output fistulas (L-OF). All patients were treated percutaneously. Percutaneous catheter drainage was successful in 16 of 20 patients (80 %). The fistula healed in 13 of 15 postoperative cases (86.6 %) and in three of five primary fistulas (60 %). Treatment was successful in 14 of 16 patients (87.5 %) with H-OF and in two of four patients with L-OF. Percutaneous catheterization of the pancreatic ducts was successful in eight of 20 patients (40 %); seven of these patients were cured. Catheterization was not achieved in 12 patients and treatment failed in three (25 %). Conservative treatment of external pancreatic fistulas with percutaneous catheter-directed drainage is thus a reasonable alternative to surgery, particularly in patients with H-OF.

OBJECTIVE: Our objective was to evaluate retrospectively the results of percutaneous catheter management of enterocutaneous fistulas. SUBJECTS AND METHODS: From 1983 to 1995, 147 patients with enterocutaneous fistulas were referred to our department after at least 1 month of unsuccessful medical treatment. One hundred eleven of these patients (76%) had developed fistulas after surgery. Ninety-three of 147 patients (63%) had high-output fistulas, and 54 (37%) had low-output fistulas. Patients underwent fluoroscopically guided catheterization of the fistulous tracts and cannulation of the enteric segments. Abscesses were drained either through the cutaneous orifice or under CT or sonographic control when no communication with the fistulous tract existed. RESULTS: We defined success as closure of the fistulous tract and the cutaneous orifice and definitive healing of abscesses. The overall closure rate was 81%. The respective clinical success rates for high-output fistulas and low-output fistulas were 90% with a mean duration of 32 days and 65% with a mean duration of 45 days. CONCLUSION: Percutaneous management of enterocutaneous fistulas is a valuable therapeutic approach in patients not responding to medical treatment, particularly patients with high-output fistulas.

Chronic nonischemic disturbance of mesenteric venous blood flow is reported in 11 patients with a mean age of 19 years. This entity, rarely discussed in the literature, is different from acute thrombosis and chronic thrombotic forms with portal hypertension or hypercoagulopathy. In eight patients this syndrome was secondary to organic lesions of different origin: mesenteric vein squeezed by fibrous bands or an abnormal jejunal artery (four cases), lymphoma involving the distal superior mesenteric veins (three cases), hemangioma causing microthrombi (one case). In three patients no etiology or predisposing factor was found. All patients presented with rectal hemorrhage. Small bowel enema showed a constant pattern in 11 patients: small nodules, modified by compression or peristalsis, involving the mesenteric border of the jejunoileal segment, and associated with thick, straight but regular folds. Mesenteric varices were suspected and led to angiographic studies which were normal in three cases, confirmed varices in eight cases, and thrombosis in four cases. Laparotomy was normal in three cases and established the etiological diagnosis in eight cases. Varices were shown in six cases. Arteriography and laparotomy were unable to reach a complete diagnosis.
