Vietnam officially integrated into the Internet in 19th November 1997. The health sector actively prepared for connecting the Internet via National gate, currently set up the local area network (LAN) to establish the Intranet of the sector. The Internet the central institute for medical science information would be major institute for setting up this tool.

Background: peripheral vascular wounds/trauma is a severe type of surgical emergency, the increasing rate due to the rapid increase of traffic, labor and living accidents. Subjectives and Method: retrospective study, all patients with peripheral vascular wounds/traumas (alone or combination in multiple trauma) were emergency operated at Viet Duc Hospital from January 2004 to June 2006. Results: A total of 310 patients with peripheral vascular injuries in the study, of which accounted for 62.3% of injury, trauma group accounted for 37.7%. The mean age of 30. In first aid, pressed tape accounted for high rate (71.5%). Rate of popliteal vascular trauma due to fractures around the knee accounted for 65.5%, the rate of brachial vascular trauma with fractures around the elbow was 50%. Rate of late diagnosis of arterial trauma was 14.6%, higher than the arterial wounds (2.6%). The rate of ultrasound for forelimbs - where vessels were many wounds, was lower than that for hindlimbs - where vessels were many traumas (44% vs 67.9%). For vascular wounds, more directly vascular connection and more intervention on veins, whereas, for arterial trauma, more vascular graft. Rate of complications was low (7.4%), with no deaths. Conclusions: Overall, the results of emergency surgery for peripheral vascular wounds/trauma were well. No cases was death from vascular lesions, rate of complications was low.

Background/Aims: Accurate neoplastic prediction can significantly decrease costs associated with pathology and unnecessary colorectal polypectomies. Narrow band imaging (NBI) and dual-focus (DF) mode are promising emerging optical technologies for recognizing neoplastic features of colorectal polyps digitally. This study aimed to clarify the clinical usefulness of NBI with and without DF assistance in the neoplastic prediction of small colorectal polyps (<10 mm). Methods: This cross-sectional study included 530 small colorectal polyps from 343 consecutive patients who underwent colonoscopy at the University Medical Center from September 2020 to May 2021. Each polyp was endoscopically diagnosed in three successive steps using white-light endoscopy (WLE), NBI, and NBI-DF and retrieved for histopathological assessment. The diagnostic accuracy of each modality was evaluated with reference to histopathology. Results: There were 295 neoplastic polyps and 235 non-neoplastic polyps. The overall accuracies of WLE, WLE+NBI, and WLE+NBI+NBI-DF in the neoplastic prediction of colorectal polyps were 70.8%, 87.4%, and 90.8%, respectively (p<0.001). The accuracy of WLE+NBI+NBI-DF was significantly higher than that of WLE+NBI in the polyp size ≤5 mm subgroup (87.3% vs. 90.1%, p<0.001). Conclusions NBI improved the real-time neoplastic prediction of small colorectal polyps. The DF mode was especially useful in polyps ≤5 mm in size.

Ischemic colitis (IC) is an underreported chronic disease characterized by the hypoperfusion of the bowel mucosa. The diagnosis and treatment may be challenging because its clinical course resembles other colitis or even colorectal malignancies. This paper reports an untypical case to underline the diversity of IC manifestation. A 68-year-old man with several comorbidities was admitted because of abdominal pain with a 6-month duration and a mass in the left lower quadrant. Colonoscopy revealed erosive pseudomembranous colitis narrowed colon segments with ulcerated mucosa mimicking colorectal cancer and inflammatory bowel disease. The stool cultures and Clostridium difficile toxin tests were negative. After the failure of conservative therapy, the Hartmann procedure with temporary ileostomy was performed uneventfully. The histological results of the surgical specimens revealed IC with focal pseudomembranous areas.
