INTRODUCTION Visceral artery aneurysms are an infrequent entity. Most of them are asymptomatic, but when they present as a rupture, a high mortality is associated. MATERIAL AND METHODS We review our experience of 18 cases between 1988 and 2006. RESULTS 9 males and 9 females with a mean age of 66,5 years are analyzed. Aneurysms were located in splenic(More)
INTRODUCTION Pancreatic neuroendocrine tumours (PNT) are infrequent epithelial neoplasms associated with a better outcome than pancreatic adenocarcinoma. MATERIALS AND METHODS We analysed our 22 years of experience in managing PNT. Forty-nine patients (27 women and 22 men) with a mean age of 49 years were studied. There were 28 insulinomas, eight(More)
Twenty-eight patients with genital and perianal necrotizing infections are described. The patients were divided into three groups according to the primary site of infection: group 1, anorectal (14 patients); group 2, urologic (ten patients), and group 3, idiopathic (four patients). The overall mortality was 25 percent, 28.5 percent for the anorectal group(More)
INTRODUCTION Laparoscopic surgery has become the elective approach for the surgical treatment of gastroesophageal reflux disease (GERD) in the last decade. Outcome data beyond 10 years are available for open fundoplication, but few studies report long-term follow-up after laparoscopic fundoplication and comparison between laparoscopic and open approaches.(More)
Laparoscopic surgery has become the elective approach for the surgical treatment of gastroesophageal reflux disease in the last decade. Outcome data beyond 10 years are available for open fundoplication, with good-to-excellent results, but few studies report long-term follow-up after laparoscopic fundoplication. We performed a retrospective study of all the(More)
INTRODUCTION Radiation enteritis is a complication of radiation therapy for pelvic tumours. It appears after a variable period of time and is often progressive. MATERIAL AND METHODS We analyse our experience of 77 cases (52 females and 25 males) diagnosed with radiation enteritis or proctitis between 1986 and 2006. RESULTS The most frequent location of(More)
The purpose of this article was to review the effectiveness of follow-up in patients with colorectal cancer submitted to curative treatment. A comprehensive follow-up involves rational initial management of the primary tumor, knowledge of prognostic factors, selection of the patient to be followed, determination of the time for follow-up, use of the most(More)
The purpose of this article was to study the effectiveness of a prospective follow-up programme in patients after curative surgery for colorectal cancer. Of the initial 151 selected patients, 61 (40%) developed a recurrence in whom only six cases (10%) of potentially curable recurrent lesions were detected. The first clues to recurrence in the 61 patients(More)
A study was made of the histologic changes in the mucosa of the ileoanal reservoirs of 10 patients who 2 years earlier had undergone ileoanal anastomosis with a J reservoir for ulcerative colitis (CU). In biopsies of the reservoirs were evaluated: 1) basic morphologic changes; 2) morphometric differences with respect to normal ileal mucosa; 3) the(More)
