A restrospective study on the 13 patients with primary malignant non-Hodgkin lymphoma of the small intestine operated in Viet Duc hospital from 1990 to 1999 has shown that the clinical features with general changes of symptoms: weakness, anorexia, weight loss, abdominal pain and abdominal node. No patients were diagnosed by X-ray. 8 patients with ileal tumor and 2 patients with duodenal tumor were diagnosed. The histopathology was not distinguished. The basic treatment is operation for removal. The classification the disease’s period which helps the combination of chemicals with radiation after operation for prolonging the life of patients.

Rectal submucosal lesions encompass a wide variety of benign and malignant tumors involving the rectum. With optical colonoscopy, any mass-like protrusion covered by normal mucosa, whether the underlying process is intramural or extramural in origin, may be reported as a submucosal lesion. Whereas the assessment of submucosal lesions may be limited with performing optical colonoscopy, cross-sectional imaging such as CT, transrectal ultrasonography and MRI allows the evaluation of perirectal tissues and pelvic organs in addition to the entire thickness of the rectum, and so this is advantageous for the assessment of rectal submucosal tumors. Among these, MRI is the best investigative modality for soft tissue characterization. Therefore, knowledge of the MRI features of rectal submucosal tumors can help achieve accurate preoperative diagnoses and facilitate the appropriate management.

Breast cancer is a common malignancy in women and frequently metastasizes to various organs such as liver, lung, brain, bone and so on. But metastasis to gastrointestinal tract is rare. We describe a 73-year-old woman with small intestinal metastasis of breast cancer. She was diagnosed as right breast cancer in stage I, received modified radical mastectomy 6 years ago and had been followed up without any evidence of residual disease. During investigation for lower abdominal pain and weight loss of 9 kg, we found a small bowel mass. The histology of the tissue taken from small bowel mass was adenocarcinoma, poorly differentiated. The immunohistochemical stain of this specimen showed 75% positivity of estrogen receptor and 90% positivity of progesterone receptor. This is a case of small bowel metastasis from breast cancer and we report this case with a review of literatures.

Acolonic polyp is a circumscribed mass of tissue that projects above the surface of the intestinal mucosa, which may be classified as either pedunculated or sessile, depending on whether or not it contains a discrete stalk, and according to the size and type. It has been believed that colorectal cancer evolves from a precursor lesion, the adenomatous polyp. The introduction of colonoscopy in the early 1970s, followed by the demonstration of the feasibility of colonoscopic polypectomy, provided the technology for the application of this concept to clinical practice. Colorectal cancer can be prevented through examination of the entire colon and identification of a polyp to be resected. According to the National Polyp Study in the USA, the incidence of colorectal cancer is reduced by 76~90% following colonoscopic polypectomy. Colonoscopy and polypectomy, when performed by adequately trained physicians, is a safe and effective procedure that can decrease deaths resulting from colorectal cancer.

The technology of electronic chromoendoscopy consists of narrow band imaging (NBI) and fuji intelligent chromo endoscopy (FICE). The two skills help distinguish between normal mucous membrane and focal zone and raise the detecting rate between the abnormal proliferation and early cancer. Therefore, the exploring research for type selection index of the two technologies and systems will be beneficial to the choice of the highest cost-effective endoscopy system and to the avoidance of wasting resources. By comparing all the indexes, and with purpose of clinical usage, NBI system has advantage over the FICE system. But with purpose for scientific research, the FICE system will be the better choice.

OBJECTIVE: To evaluate the usefulness of MR imaging for diseases of the small intestine, emphasizing a comparison with CT. MATERIALS AND METHODS: Thirty-four patients who underwent both CT and MR imaging using FLASH 2D and HASTE sequences were analyzed. All patients had various small bowel diseases with variable association of peritoneal lesions. We compared the detectabilities of CT and MR imaging using different MR pulse sequences. The capability for analyzing the characteristics of small intestinal disease was also compared. RESULTS: MR imaging was nearly equal to CT for detecting intraluminal or peritoneal masses, lesions in the bowel and mesentery, and small bowel obstruction, but was definitely inferior for detecting omental lesions. The most successful MR imaging sequence was HASTE for demonstrating bowel wall thickening, coronal FLASH 2D for mesenteric lesions, and axial FLASH 2D for omental lesions. MR imaging yielded greater information than CT in six of 12 inflammatory bowel diseases, while it was equal to CT in six of seven neoplasms and inferior in five of seven mesenteric ischemia. In determining the primary causes of 15 intestinal obstructions, MR imaging was correct in 11 (73%) and CT in nine (60%) patients. CONCLUSION: MR imaging can serve as an alternative diagnostic tool for patients with suspected inflammatory bowel disease, small intestinal neoplasm or obstruction. is a high-speed, heavily T2-weighted sequence with a great sensitivity for fluid (11). This advance may make it possible to use breath-hold turbo spin-echo MR.

Small bowel capsule endoscopy has been now widely applied for patients who are highly suspected of small bowel disease with occult bleeding and unexplained abdominal pain. Capsule retention is a major complication, with an overall incidence of 1%-2%, commonly seen in the detection of Crohn's disease and small bowel tumors. Most cases run asymptomatically after retention, while intestinal obstruction or perforation can occur ralely. Conservative methods, endoscopic or surgical interventions are performed to deal with the retention. Patency capsule is currently used as a novel tool to reduce the risk of capsule retention.
