[Giant colonic diverticulum]

SARLÓS Géza, GARAMSZEGI Mária, GREXA Erzsébet

[INTRODUCTION - Very rarely do colonic diverticula grow enourmously - from 3-4 cm upto 15-20 cm in diameter - causing diagnostic difficulties. PATIENT AND METHODS - The authors present a case of an elderly male patient where the ultrasound examination accidentally revealed irregularity in a part of the sigmoid colon with thickened wall. This finding was then examined by colonoscopy, colonography (double contrast barium enema) and CT. Two giant diverticula, measuring 4-5 cm in diameter, arising from the sigmoid colon were demonstrated. Considering the old age of the patient and the lack of clinical symptoms, the affected part of the sigmoid colon had not been surgically resected. CONCLUSION - Giving a general overview on the pathogenesis, presentation and differential diagnosis of colonic diverticula, the authors emphasise the importance of colonography. Also, as far as the authors know, this is the first Hungarian report on giant colonic diverticulum.]

[DIVERTICULOSIS, DIVERTICULITIS - SYMPTOMS, DIAGNOSTICS AND TREATMENT]

NÉMETH Anna Mária, ENDER Ferenc, BANAI János

[Diverticulosis of the colon is frequent in developed countries. Decreased intake of dietary fibre have been implicated as an important pathogenetic factor. Most of the affected patients are asymptomatic but 10-20% of them have abdominal problems. Clinical manifestations range from simple, non-complicated form (abdominal pain, distension, constipation, urgency etc.) to severe complications (diverticulitis, abscess, peritonitis, perforation, haemorrhage etc.) The diagnosis and therapy of different forms of diverticular disease can be very simple but in several cases differential diagnostical problems and therapeutical difficulties may arise. The gold standard for establishment of uncomplicated diverticulosis is the barium enema or colonoscopy. In case of complicated forms non-invasive methods (US, CT scan, CT-colonography, MRI) have to be preferred. These examinations have no risk for perforation and extraintestinal pathology (air, fluid, abscess) can be detected. Colonoscopy or angiography are the methods of choice in case of haematochesia. The choice of therapy is based on clinical presentation, symptoms and pathology. Fibre supplementation is recommended for patients with diverticulosis without symptoms. In case of noncomplicated symptomatic diverticular disease fiber supplementation or cyclic administration of broad spectrum, poorly absorbable antibiotic can be effective in the prevention of inflammatory episodes and complications. If some of the severe or recurrent complications can not be treated conservatively, surgery is necessary. Prevention of diverticulosis and diverticular disease has to be emphasized. While fibre supplementation in the diet is recommended, other efficacious preventive strategies remain to be identified.]

[Recent advances in the radiology of colon cancer - Onco Update 2004]

KOLLÁR Attila

[The recent literature of colon cancer imaging, colonic stenting and the interventional treatment of colorectal liver metastases is overviewed. The introduction of virtual colonoscopy in the diagnosis of colon cancer drew attention in the last years and it is one of the most rapidly developing method. Several new publications was published about CT and MR colonography in the past one and half year. Nowadays, beside the double contrast barium enema and the colonoscopy (as gold standard), CT and MR colonography plays more and more important role. These methods can be applied only with multislice CT and modern MR machines equipped with appropriate softwares. Since these equipments are available only in limited number in Hungary, these methods has not been used in the daily practice. Development of interventional methods, like stenting of obstructive colon tumor and the percutaneous and intraarterial interventional treatment of colorectal metastases play more and more important role in the therapy, as indicated in the literature.]

[Role of imaging in the managment of colorectal cancer]

JEDERÁN Éva, GŐDÉNY Mária

[Colorectal cancer is the third most common cancer worldwide and the second most common cause of cancer death in Hungary. Diagnosis requires the examination of the entire large bowel by means of radiological and/or endoscopic techniques. Colorectal cancer primarily develops from adenomatous polyp over a period of 10-15 years. Tumour staging is crucial for the prognosis and for the planning of the most suitable anticancer therapy. The role of imaging in colorectal cancer is increasing with the change in complex tumour therapy. With advances in ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) techniques accuracy of imaging has improved. The accuracy of CT improved with the advent of the multislice technique (MDCT). Sensitivity and specificity of CT colonography (CTC) in colon polyps and cancer is over 90%, therefore it is one of the screening tools. Accuracy of the CTC is comparable to the optical colonoscopy, complements conventional colonoscopy well and it is an effective tool in the right hands. Endorectal US (ERUS) depicts the anatomic layers of the rectal wall with high degree of accuracy, therefore it is the best method for the evaluation of the lower tumour stage. High resolution MRI is the most suitable technique for predicting rectal tumor stage, therefore it has been established as the standard for preoperative assessment of rectal cancer.]
