In this study, we describe case report of 70-year-old man was admitted to our hospital because of abdominal pain over 6 months with no pathological antecedent. Patient has laparoscopic surgeon, diagnosis was a pedunculated exoluminal gastrointestinal stromal tumor (GIST). Histopathological examination report and the CD-117 immunoreactive score is suitable of endoscopically invisible medium sized.

Trước khi chữa, để biết ung thư đã lan đến đâu, chúng ta cần soi toàn ruột già (nếu chưa soi), chụp phim ngực (chest x-ray), phim Cat scan bụng và vùng chậu (abdominal and pelvic CT scan). Khám phá sớm trong giai đoạn A, khi ung thư mới còn trên lớp niêm mạc, chưa ăn sâu xuống lòng của ruột già, sự chữa trị giản dị, ta mổ cắt bướu ung thư là xong, và tỉ lệ sống sót được 5 năm (5-year survival rate) của người bệnh rất cao, trên 90%. ...

Diagnosis Scanning procedures have considerably facilitated the diagnosis of intraabdominal abscesses. Abdominal CT probably has the highest yield, although ultrasonography is particularly useful for the right upper quadrant, kidneys, and pelvis. Both indium-labeled WBCs and gallium tend to localize in abscesses and may be useful in finding a collection. Since gallium is taken up in the bowel, indium-labeled WBCs may have a slightly greater yield for abscesses near the bowel.

Carcinoma of the Ampulla of Vater This tumor arises within 2 cm of the distal end of the common bile duct, and is mainly (90%) an adenocarcinoma. Locoregional lymph nodes are commonly involved (50%), and the liver is the most frequent site for metastases. The commonest clinical presentation is jaundice, and many patients also have pruritus, weight loss, and epigastric pain. Initial evaluation is performed with an abdominal ultrasound to assess vascular involvement, biliary dilatation, and liver lesions. This is followed by a CT scan, or MRI and especially MRCP.

Staging of Small Cell Lung Cancer Pretreatment staging for patients with SCLC includes the initial general lung cancer evaluation with chest and abdominal CT scans (because of the high frequency of hepatic and adrenal involvement) as well as fiberoptic bronchoscopy with washings and biopsies to determine the tumor extent before therapy; brain CT scan (10% of patients have metastases); and radionuclide scans (bone) if symptoms or other findings suggest disease involvement in these areas.

Chest radiographs and CT scans are needed to evaluate tumor size and nodal involvement; old radiographs are useful for comparison. CT scans of the thorax and upper abdomen are of use in the preoperative staging of NSCLC to detect mediastinal nodes and pleural extension and occult abdominal disease (e.g., liver, adrenal), and in planning curative radiation therapy. However, mediastinal nodal involvement should be documented histologically if the findings will influence therapeutic decisions.
