Although the ultrasonography has been regarded as a important procedure in the diagnosis of intraabdominalabscess, there were relatively few papers concerning the ultrasonographic findings of periappendiceal abscess.Nineteen cases of surgically proven periappendiceal abscess caused by perforated appendicitis were studied byultrasonography at the Kyung Hee University Hospital during last 34 months. The results were as follows; 1.Diagnostic accuracy of the real-time ultrasonography was 94.7%(18/19). There were only one false positive and onefalse negative. 2. The location of abscesses were ; periappendiceal 68.4%(13/19), pelvic 21.0%(4/19), subhepatic5.3%(1/19) and subphrenic 5.3%(1/19) in order of frequency. 3. Variable echo-patterns of abscesses wereencountered. But irregular, thick walled, posteriorly reinforcing, echo-free or mixed echo-patterns were mostcommon.

157 patients with the amebic hepatic abscess diagnosed and treated in Viet Duc hospital during 1995 - 1998. The number and position of abscess focuses were identified by ultrasound. The sound intensity in the abscess focus was reduced. The abscess focus located in the right liver (80.90%), right side of the liver (50%), posterior lobe (50%) anterior lobe (30.90%), and medial lobe (4.49%). After diagnosis, 55 cases (50.32%) and 23 cases received operations (14.65%).

The ultrasound images of the amoebic hepatic abscess during the internal treatment were studied to evaluate the disease's progress and the response to the available guideline of treatment. The ultrasound's features and the distribution of the abscess focuses in 55 patients with the amoebic hepatic abscess during the treatment (6 months - 10 years) were evaluated. The conclusion: the diagnosis should base on the ultrasound, clinical features and needle aspiration as the guidance of the ultrasound.

The pelvic abscess communicating with the appendix is relatively rare, however, it could be diagnosed preoperatively by various diagnostic modalities such as ultrasonography, computed tomography or laparoscopy. We experienced a case of pelvic abscess presented as a pelvic mass invading vesical wall, and report this unusual presentation with a brief review of literature.

Although many papers concerning the ultrasonographic findings of liver abscess have been appeared, there is afew literatures for the analysis of its echognic patterns. Twenty-nine cases of surgically proven liver abscesswere studied by ultrasonography in our hospital during recent 3 years. The results were as follows: 1.Ultrasonography permitted correct diagnosis in 26 of 29 patients with sensitivity 90%. 2. All the 7 cases ofamebic abscess were single lesions and 6 cases of them were distributed in the right lobe of liver, while pyogenicabscesses showed single or multiple lesions. It was very difficult to distinguish pyogenic abscess from amebicabscess in cases of single lesion. 3. It was impossible to differentiate pyogenic abscess from amebic abscess bythe echopattern of abscess wall and internal echogenicity. 4. The wall of obscess was ill-defined in the majority,and internal echogenecity of abscess was variable although weak internal echogenecity was more comon. 5. Theechopattern of abscess was gradually converted to echolucent or hypoechoic area with weak internal echoes infollowing up study. 6. Clinical findings and ultrasonic findings should be carefully analysed to secure correctdiagnosis of there is any possibility of co-existing necrotizing metastatic lesion.

BACKGROUND: Successful treatment of a fistula in ano (FIA) depends on identifying track of the fistula and the internal opening at the time of surgery as well as on eradicating them by appropriate surgery. Transanal ultrasonography (TUS) has been known to be an useful tool for the evaluation of anorectal inflammatory lesion, such as perianal abscess and FIA. Preoperative TUS was performed to determine the accuracy in respect to detection the of fistula track and the internal opening. METHODS: One hundred nineteen patients were examined by preoperative TUS among 176 patients with FIA treated from January 1996 to December 1997. TUS findings were compared with operative findings in respect to location of track, types and primary opening of the fistula. TUS was performed by using the Scanner type 2001 with an attached endoprobe. RESULTS: The track of fistula on preoperative TUS was identified in 119 cases, and TUS findings were not identical with operative findings in 14 cases. The accuracy of determining the fistula track was 88.2%. The most common type of fistula and the location of primary opening were intersphincteric type (53.0%) and posterior aspect (52.7%) respectively. The accuracies were 95% in intersphincteric type, 90.5% in transsphincteric type, 90% in suprasphincteric type and 62.5% in extrasphincteric type. Accurate identification of the internal opening was possible in 91 of the 119 cases. External sphincter damage was identified in 3 cases, and all of them were treated by sphincteroplasty at the time of surgery. CONCLUSIONS: TUS is an accurate and minimally invasive method to identify the fistula track in relation to the anal sphincters and internal opening.

An isolated pyogenic pancreatic abscess (IPPA) without pancreatitis is extremely rare but can occur in patients with uncontrolled diabetes. This pathologic condition poses a clinical challenge in diagnosis and management because it can be confused easily with a malignancy. Endoscopic ultrasound (EUS) may be a useful diagnostic modality for indeterminate pancreatic lesions and IPPA. Here, we report two cases with elevated carbohydrate antigen 19-9 levels and pancreatic masses on cross sectional imaging. The patients were subsequently diagnosed with IPPA by EUS. EUS-guided drainage was performed successfully and the patients' clinical symptoms and radiologic findings improved. In our experience, EUS and EUS-guided drainage are crucial steps for the diagnosis and management of patients with an indeterminate pancreatic lesion. In addition, EUS-guided drainage has excellent technical and clinical outcomes for the treatment of IPPA.

142 patients underwent diagnostic ultrasonography. Out of these, 100 patients have liver tumor and 42 have liver abscess. The prevalence is higher in male than in female and higher in 20-60 years of old than in other age groups. Liver tumor and abscess are more likely to be seen in right lobe than in left lobe with size of 5-10cm (55.7%). For liver abscess, sound reduction is more common (25.03%), while for liver tumor, sound combination and mixes are common types.

55 cases of amoebic hepatic abscess diagnosed basing on the clinic, ultrasound B-mode and Doppler in 1998 in Hå ChÝ Minh medical center. The duration of disease was 6-10 days. Of which 10 cases were monitored continuously until the disease free. There was no specific image of amebic hepatic abscess on the ultrasound. Most of abscess focused in the right liver. The size of abscess was reduced gradually as duration of the treatment. The conclusion: the ultrasound helps the needle aspiration of the complicated diseases and monitors the response of the treatment.

OBJECTIVE: We report six patients with tuboovarian abscess (TOA) drained through sonographically guided transrectal route, in whom percutaneous or transvaginal approach was not accessible due to the risk of pelvic organ. METHOD: This procedure was performed under the guidance of transrectal ultrasound. Six patients with aged 25-42 years (mean 31.6 years), who had appendectomy(1), C/S(2), hyterectomy(1) and no operaion Hx(2). Size of abscess cavity was variable from three to eight centimeter. Catheter was removed when drainage amount was reduced less than 10 cc and the patient becomes afebrile. RESULT: Drainage was successfully done in all patients without any complication to the procedure. Fecal contamination was not occurred after transrectal drainage due to abdominal pressure and gravity ought to empty the abscess cavity. There was no problem in defecation due to the catheter and in its expulsion by defecation. Catheter was removed after 3-8 days (mean 6 days) without recurrent abscess. CONCLUSION: Transrectal drainage of abscess performed with ultrasound guidance is a safe, feasible procedure, which is well tolerated by patient and relatively easy procedure.
