The open any center receiving patients, irrespective volume. main outcome 30-day...
Abstract Colorectal cancer is the third leading cause of cancer-related mortality in Brazil. Proper staging crucial for management patients with rectal cancer, as implemented therapies may result implications prognosis and quality life. The therapeutic armamentarium has evolved over time, highlighting importance magnetic resonance imaging (MRI) preoperative evaluation. This study aims to assess correlation between clinical by MRI pathological individuals cancer. Cross-sectional observational...
Anal sphincter tone is routinely assessed by digital rectal examination in patients with fecal incontinence, although its accuracy detecting defects or separating competent from incompetent muscles has not been established.In this setting, we aimed to evaluate the of grading anal order separate small extensive cases as depicted on 3D endoanal ultrasound, using a scoring defect and correlate pressures.Women incontinence were divided into two groups: according ultrasound system. Sensitivity,...
BACKGROUND: Colorectal cancer is a major cause of morbidity and mortality can arise through the adenoma-carcinoma sequence. Colonoscopy considered method choice for population-wide screening. AIM: To assess characteristics endoscopically resected polyps in consecutive series patients who underwent colonoscopy at university hospital compare histopathology findings according to patient age polyp size. METHODS: Retrospective, cross-sectional 1950 reports from consecutively examined patients....
Proficiency and competence of endoscopists is perhaps the mainstay successful diagnostic therapeutic colonoscopy.To analyze indications, findings, complications colonoscopies performed by resident physicians in a university teaching hospital.Were analyzed 1,000 consecutively fourth-year residents under direct supervision experienced colonoscopists. Information on patients' demographic data, bowel preparation, indications for procedure, success were obtained.A total 596 (59.6%) female 404...

The animals group received intraperitoneal SMT at 50 mg/kg/dose every 12 hours for 72 hours. saline same volume SMT. subdivided subgroups 10 euthanasia third, seventh, 14th postoperative days (POD). We evaluated clinical weight evolution, breaking strength histopathology; also, a blood sample...
Abstract Objective Laparoscopic approach should be offered for most patients requiring colectomy, as it is a safe procedure, associated with shorter hospitalization, better cosmetic results, and does not affect negatively the oncological outcomes of colon cancer. However, there no consistent data on safety laparoscopic surgery training during residency. Therefore, aim this study was to assess whether or resident par- ticipation in colectomy affected postoperative outcomes. Methods The...

Method: Patients a diagnosis stages I-IV 2010 2020 were identified from prospective database tertiary single center. Right left-sided compared regarding results. Survival analysis conducted using Kaplan–Meier method adjusted hazard...
Abstract Introduction McKittrick-Wheelock syndrome is a rare condition that arises from hypersecretory state secondary to large colorectal tumors, mainly villous adenomas, leading an electrolytic disorder associated with chronic diarrhea usually persists for years. It relatively unknown disease can lead severe complications such as acute kidney injury, hyponatremia, and hypokalemia. In fact, it causes death in most untreated cases. Surgical removal of the tumor successful treatment, symptoms...
