Evaluation of recurrence and surgical complementation rates after endoscopic resection of large colorectal non-pedunculated lesions.

Background And Aim: the process that leads to the development of colorectal cancer takes many years and most tumors originate from polyps and non-polypoid lesions. Techniques of endoscopic resection are surgical treatment options, even in case of large lesions or with initial invasion. This study aimed to evaluate the recurrence and surgical complementation rates after endoscopic resection of large colorectal non-pedunculated lesions.

ENDOSCOPIC BAND LIGATION FOR THE TREATMENT OF HEMORRHOIDAL DISEASE.

Background: There are several therapeutic options for symptomatic hemorrhoids, from hygienic and dietary measures to conventional surgery. The best technique adopted for alternative and non-surgical treatment for intermediate grade (II and III) hemorrhoidal disease is rubber band ligation. More recently, the technique has been used with the aid of a gastroscope and a kit of elastic rubber bands for esophageal varices.

Cytomegaloviral colitis in HIV positive patients: endoscopic findings.

Background: Diarrhea in seropositive human immunodeficiency virus patients is one of the most important and disabling symptoms, and often decreases their quality of life. Cytomegalovirus colitis is among the principal causes of this symptom and colonoscopy is the gold standard examination to diagnose it.

Aim: To define the main endoscopic findings in seropositive human immunodeficiency virus patients with cytomegalovirus colitis.

Magnifying colonoscopy: interobserver agreement in the assessment of colonic pit patterns and its correlation with histopathological findings.

Background And Study Aims: Magnifying colonoscopy (MC) is recognized as an aid to the differential diagnosis between neoplastic and nonneoplastic lesions. This study evaluated interobserver agreement of experienced endoscopists in the assessment of colonic pit patterns through the Kudo's classification and correlated morphological aspects with histopathological findings.

Materials And Methods: A total of 213 magnification chromoendoscopic pictures of colonic lesions were collected from 161 consecutive patients and presented to three independent observers who expressed opinion about predominant pit pattern.

[High resolution chromoendoscopy in the differential diagnosis of neoplastic and non-neoplastic polyps].

Background: Magnifying colonoscopy brought the possibility of precise histologic diagnosis of colorectal lesions through their surface appearance. Despite the high accuracy of magnifying colonoscopy it is a specialized and expensive equipment not available in most medical centers. Due to these reasons the use of conventional colonoscopy with chromoscopy has been raised because this produce can reproduce most of the information previously obtained by magnifying colonoscopy.

Laparoscopic treatment of intestinal intussusception in the Peutz-Jeghers syndrome: case report and review of the literature.

The hamartomatous polyps of Peutz-Jeghers Syndrome (PJS) can cause repeated episodes of rectal bleeding and intestinal subocclusion. Laparoscopic treatment of intussusception is rarely reported and must be considered for this clinical condition. We described a 35-year-old male with PJS who presented with rectal bleeding and abdominal pain.
