RESUMEN
BACKGROUND AND STUDY AIM: To reduce the costs of colonoscopy the feasibility of unsedated procedures has been explored. The aims of our study were to assess patient satisfaction with on-demand sedation and identify factors related to painful colonoscopy. PATIENTS AND METHODS: The Norwegian Gastronet quality assurance documentation tools consist of endoscopy reports (completed on site) and a patient satisfaction questionnaire (completed by the patient on the day after colonoscopy). Data were collected from January 1 2004 to December 31 2006. Colonoscopies reported to be moderately or severely painful were defined as "painful colonoscopy." RESULTS: Nine endoscopy centers representing 86 endoscopists reported 14 915 examinations and 12 354 patient reports were returned (83 % response rate). Patient satisfaction with service and information given was greater than 95 % for all centers. Mean rate of painful colonoscopy was 34 % and mean sedation rate 34 %. Odds ratio (OR) for painful colonoscopy was 2.2 ( P < 0.001) when sedation was given. The ORs for painful colonoscopy were similar for all but one center (no. 4) with OR 1.6 ( P = 0.04), while the OR for giving sedation was higher for all but one center (no. 1) compared with the reference center (ORs 2.2 to 7.5, all P-values < 0.001). CONCLUSION: A surprisingly high rate of painful colonoscopy was found. High sedation rates were not associated with low rates of painful colonoscopy. Recommending increased sedation rates as the only intervention to improve suboptimal performance might not lead to lower rates of painful colonoscopy.

Discontinuation of thromboprophylaxis a few days after surgery may unmask delayed hypercoagulability and contribute to late formation of deep venous thrombosis (DVT). To investigate whether thromboprophylaxis should be prolonged beyond the hospital stay, a prospective, double-blind randomised study was conducted in 308 patients. All patients received initial thromboprophylaxis with dalteparin, dextran and graded elastic stockings. On day 7, patients were randomised to receive dalteparin (Fragmin) 5000 i.u. once daily, or placebo, for 4 weeks. All patients were subjected to bilateral venography, perfusion ventilation scintigraphy and chest X-ray on days 7 and 35. Patients with venographically verified proximal DVT on day 7 were withdrawn from the randomised study to receive anticoagulant treatment. The overall prevalence of DVT on day 7 was 15.9%. On day 35, the prevalence of DVT was 31.7% in placebo-treated patients compared with 19.3% in dalteparin-treated patients (p = 0.034). The incidence of DVT from day 7 to day 35 was 25.8% in the placebo-treated group versus 11.8% in the dalteparin-treated group (p = 0.017). The incidence of symptomatic pulmonary embolism (PE) from day 7 to day 35 was 2.8% in the placebo-treated group compared with zero in the dalteparin-treated group. This included one patient who died from PE. No patients experienced serious complications related to the injections of dalteparin or placebo. This study shows that prolonged thromboprophylaxis with dalteparin. 5000 IU, once daily for 35 days significantly reduces the frequency of DVT and should be recommended for 5 weeks after hip replacement surgery.

The incidence of tuberculous disease is increasing all over the world, mostly in the poor, developing countries, but also in some industrialized countries. In Norway, extrapulmonary tuberculosis is a rare phenomenon. It is found mostly among older Norwegians and in younger immigrants from the third world. Since the disease is rare, it may be overlooked or confused with malignant disease. We describe two patients with unusual forms of extrapulmonary tuberculosis, both mimicking neoplastic disease. The first patient was a 27-year-old woman from South-East Asia, who was operated on for suspected intraductal comedo-type carcinoma of the breast, but histological examination showed tuberculous mastitis. The second patient was a 26-year-old man from East Africa with a medical history indicating intra-abdominal lymphoma. The final diagnosis, however, was mesenteric tuberculous lymphadenitis. Both patients were treated successfully with isoniazid, rifampicin and pyrazinamide.

A cross-over test in intra-arterial digital subtraction angiography (IADSA) of the carotid arteries was performed in 50 patients to evaluate image quality and side-effects with iohexol and metrizoate injected at concentrations of 100 mg I/ml by hand. The image quality was excellent or good in all cases. Although the severity and the frequency of side-effects were higher with metrizoate, both contrast media were suitable for IADSA at this low concentration. No complications were seen. It was assumed that the risk with IADSA was less than that of conventional precerebral angiography when performed semi-selectively and with small amounts of contrast media, as in this study.
