The ultrasonography(US) is one of very important item for abdominal evaluation. Especially for the routine check of the abdomen, the US becomes the essential part of the precedure. Though the abdominal US is simple and easy, its value is very high for detection of various morphological changes of abdominal organs. The study techniques of US, common abdominal abnormalities, standardization of image interpretation, and clinical significance of the lesions, etc, were discussed.

In this report, we present a case of successful treatment of a bowel fistula in the open abdomen by perforator flaps and an aponeurosis plug. A 70-year-old man underwent total gastrectomy and developed anastomotic leakage and dehiscence of the abdominal wound a week later. He was dependent upon extracorporeal membrane oxygenation, continuous hemodiafiltration, and a respirator. Bowel fluids contaminated the open abdomen. Two months after the gastric operation, a plastic surgery team, in consultation with general surgeons, performed perforator flaps on both sides and constructed, as it were, a bridge of skin sealing the orifice of the fistula. The aponeurosis of the external oblique muscle was elevated with the flap to be used as a plug. The perforators of the flaps were identified on preoperative and intraoperative ultrasonography. This modality allowed us to locate the perforators precisely and to evaluate the perforators by assessing their diameters and performing a waveform analysis. The contamination decreased dramatically afterwards. The bare areas were gradually covered by skin grafts. The fistula was closed completely 18 days after the perforator flap. An ultrasound-guided perforator flap with an aponeurosis plug can be an option for patients suffering from an open abdomen with a bowel fistula.

Ingestion of foreign bodies (FBs) is a common phenomenon among young children. Plain radiography is the first step diagnostic modality to detect the radio-opaque FBs. And computed tomography has been recommended by several guidelines as useful modalities for diagnosing ingested FBs. However, there is a risk of radiation exposure, making it burdensome to use in asymptomatic patients. Ultrasound (US) is not a commonly used technique for diagnosing ingested foreign bodies. However, US can provide real-time imaging with good resolutions without radiation exposure in pediatric patients. Herein, we report two pediatric cases of metallic foreign body ingestion that were successfully diagnosed using US for localizing foreign bodies. This study indicates that US may be used as an alternative method for detecting the localization of metallic foreign bodies in the gastrointestinal tract without exposure of radiation, particularly in pediatric patients.

Necrotizing fasciitis is an uncommon yet fatal soft tissue infection. Current recommended treatment includes antibiotics with repeat surgical exploration and wound debridement followed by reconstruction. In burn patients, the Meek micrograft has demonstrated a higher true expansion ratio, faster reepithelialization rate, more resilient toward infection, and reduced risk of graft failure as compared with meshed graft. To our best knowledge, the use of Meek micrografting technique in reconstruction of postdebridement wounds of necrotizing fasciitis has not been reported. Hereby, we present a case of a 57-year-old gentleman who was referred to us for wound reconstruction after surgical debridement of Fournier's gangrene and extensive necrotizing fasciitis involving the anterior abdomen and bilateral femoral region. Meek micrografting technique was used to reconstruct the anterior abdomen as the wound bed was large. Although the graft was complicated with a small area of localized infection, it did not spread across the entire graft and was successfully treated with topical antibiotics and regular wound dressing. In our case, wound reconstruction using Meek micrografting technique in a patient with extensive necrotizing fasciitis was successful and showed positive outcome. Therefore, we suggest further studies to be conducted to investigate the applications and outcomes of the Meek micrografting technique, especially in patients with extensive wound bed and limited donor site availability.

Purpose: The aim of this study was to describe our treatment experiences with patients who had acute abdomen (AA) with common bile duct (CBD) dilatation. Methods: The treatment outcomes in children with AA and CBD dilatation were retrospectively reviewed. According to the shape of the intrahepatic bile ducts on ultrasonography (US), the origin of the pain was estimated as choledochal cyst (CC) complication or choledocholithiasis in normal CBD. Patients with complicated CC underwent surgery, and patients with choledocholithiasis in a normal appearing CBD underwent symptomatic treatment initially. Results: Of the 34 patients, 30 (88.2%) were female. The mean age of the patients was $6.4{\pm}4.9$ (range, 0.8-17) years. Seventeen (50.0%) patients had CBD stones and 17 (50.0%) did not. Surgical treatment was performed in 20 (58.8%) patients, 2 of whom underwent preoperative stone removal with endoscopic retrograde cholangiopancreatography and an operation. Conservative treatment was applied in 12 (35.3%) patients (8 with and 4 without stones), 1 of whom developed symptom relapse and underwent an operation. Among the 8 patients with CBD stones, 4 (4/17, 23.5%) had complete resolution of the stones and recovery of the CBD diameter after conservative treatment. US findings of patients with stone showed a fusiform or cylindrical shape of the CBD in 14 (82.4%) patients. Conclusion: The presence of stones in the distal CBD and the US features of CBD dilatation may be helpful to diagnose and treat the causes of biliary dilatation. Conservative treatment can be considered as initial therapy in patients with uncomplicated CBD dilatation with stone.

Wandering spleen is a rare condition characterized by migration of the spleen from its normal position due to laxity or absence of the supporting splenic ligaments. Ultrasonography shows the absence of the spleen in left upper quadrant (LUQ) and the presentation in the lower abdomen of a homognous mass whose sonographic appearance is consistent with that of a spleen. Contrast-enhanced CT reveals the absence of the spleen in LUQ, a soft tissue mass resembling spleen in the lower abdomen, and the splenic pedicle of whirled appearance. We present a case of wandering spleen, which could be diagnosed with US and CT by the ectopic location of spleen and the whirling pattern of splenic pedicle.

Two impedance imaging systems of multi-frequency electrical impedance tomography (MFEIT) and magnetic resonance electrical impedance tomography (MREIT) are described. MFEIT utilizes boundary measurements of current-voltage data at multiple frequencies to reconstruct cross-sectional images of a complex conductivity distribution (${\sigma}+i{\omega}{\varepsilon}$) inside the human body. The inverse problem in MFEIT is ill-posed due to the nonlinearity and low sensitivity between the boundary measurement and the complex conductivity. In MFEIT, we therefore focus on time- and frequency-difference imaging with a low spatial resolution and high temporal resolution. Multi-frequency time- and frequency-difference images in the frequency range of 10 Hz to 500 kHz are presented. In MREIT, we use an MRI scanner to measure an internal distribution of induced magnetic flux density subject to an injection current. This internal information enables us to reconstruct cross-sectional images of an internal conductivity distribution with a high spatial resolution. Conductivity image of a postmortem canine brain is presented and it shows a clear contrast between gray and white matters. Clinical applications for imaging the brain, breast, thorax, abdomen, and others are briefly discussed.

Objectives : The aim of the present study is to derive further studies evaluating the effectiveness of oriental medical treatment on colon cancer patients. We present a case of a patient diagnosed with colon cancer with colon cancer with liver metastasis who has survived more than 8 years. Methods : We followed all of treatments and examination. We prescribed the patient to take HangAm-dan(HAD) three times a day for 5 years and 1 month from January, 2000 to February, 2005. Abdominal computed tomography(CT) was performed to evaluate the therapeutic efficacy and measuring concentration of carcinoembryonic antigen(CEA) in blood serum was also performed to monitor therapeutic response. Results : The patient was diagnosed with liver metastasis in September of 1999 but has survived for over 8 years since. Abdomen CT show no interval change. Conclusions : This case may give us a possibility that oriental medical treatment offers potential benefits for patients with colon cancer.
