Colon carcinoma is the most common tumor of the gastrointestinal tract. According to some investigators, insulin, epidermal growth factor (EGF) and insulin-like growth factor I (IGF-I) man be involved in the neoplastic proliferation. Insulin-binding and receptor tyrosine kinase activity were investigated in colon carcinomas and in normal colons. The insulin(More)
BACKGROUND Despite the several series in which the short-term outcomes of robotic-assisted surgery were investigated, data concerning the long-term outcomes are still scarce. METHODS The prospectively collected records of 65 consecutive patients with extraperitoneal rectal cancer who underwent robotic total mesorectal excision (RTME) were compared with(More)
AIM To determine the quantitative gene expression of KRAS codon 12 mutant, TACSTD2, Ku70 and SERIN1 in samples of tumor tissue and to relate them with clinical-pathological characteristics of colorectal cancer. METHODS Samples of tumor and normal tissue of patients surgically treated for colorectal cancer between July 2005 and July 2009 were stored in a(More)
PURPOSE To assess a rat model of cerebral ischemia induced by occlusion of the middle cerebral artery and its effect on the area of cerebral infarction. METHODS Brain ischemia was induced in 52 male Wistar rats by introduction of a 3-0 nylon suture into the middle cerebral artery for either 90 (n=28) or 120 (n=24) minutes. Ischemic injury volume was(More)
The idea of reproducing himself with the use of a mechanical robot structure has been in man’s imagination in the last 3000 years. However, the use of robots in medicine has only 30 years of history. The application of robots in surgery originates from the need of modern man to achieve two goals: the telepresence and the performance of repetitive and(More)
BACKGROUND The use of radical vaginal hysterectomy in the treatment of cervical cancer is associated with lower morbidity and a similar cure rate when compared with the abdominal approach. The present study reports a case series of radical vaginal hysterectomy followed by extraperitoneal (Mitra) or video-laparoscopic (VLP) lymphadenectomy, with comparison(More)
BACKGROUND Fecal incontinence stands for inability in maintaining the control of defecation to a socially acceptable and adequate time and place, resulting in unwanted release of gas, liquid or solid stool. The diagnosis needs multiple exams. Anorectal manometry is mandatory for this study. The correlation between manometry with electophysiological studies(More)
Angioedema of the small bowel (ASB) is an extremely rare side effect of the angiotensin-converting enzyme inhibitors (ACEI). We present a case of ACEI-induced ASB mimicking postoperative complication. The diagnosis of ACEI-induced ASB should be considered in patients using these drugs and presenting sudden gastrointestinal symptoms and thickening of small(More)
CONTEXT Laparotomy is the gold standard treatment of patients with intestinal obstruction without response to clinical management. Nowadays, literature has been demonstrating the feasibility of videolaparoscopy in the treatment of intestinal obstruction. OBJECTIVES To report the clinical-epidemiological profile of patients with intestinal obstruction(More)
