One...
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...
How is robotic-assisted surgery being developed and implemented in low- middle-income countries, what challenges do we face?

Gauze, surgical dressings, and sponges are the most frequently retained materials after abdominal surgeries. The incidence is variable underreported, mostly due legal consequences of their discovery, but also because many patients remain asymptomatic. Retained material can penetrate bowel or bladder, leading malabsorption, partial complete obstruction, gastrointestinal bleeding secondary vessel...

We report case of sepsis pneumoretroperitoneum resection rectal lateral spreading tumor. The patient presented with mucous discharge. Colonoscopy revealed underwent an transanal the lesion. He abdominal focus, imaging tests pneumoretroperitoneum. A new surgical intervention was performed loop colostomy. Despite existence other reports on microsurgery, what draws...
The LATAM-URG study was initiated to address a critical gap in the understanding of incidence, management, and outcomes urgent abdominal procedures Latin America. primary purpose this is gather comprehensive data that will inform clinical practice, improve patient outcomes, contribute global body knowledge on emergency surgical care. Specifically, aims quantify burden these procedures, assess variations identify factors high mortality associated with laparotomy region.
Aim: The purpose of the study was to identify potential differences between patients with right colon cancer and left in epidemiological, clinical presentation, pathological, surgical results addition impact sidedness on disease-free survival (DFS) overall (OS). 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...
Colorectal cancer (CRC) is among the most diagnosed malignancies worldwide, and it also second leading cause of cancer-related deaths. Despite recent progress in screening programs, noninvasive accurate biomarkers are still needed CRC field. In this study, we evaluated compared urinary proteomic profiles patients with colorectal adenocarcinoma without cancer, aiming to identify potential biomarker proteins. Urine samples were collected from 9 normal colonoscopy results. Mass spectrometry...
Background Total proctocolectomy with ileal pouch–anal anastomosis (IPAA) is the most established restorative operative approach for patients ulcerative colitis. It has associated morbidity and potential major repercussions on quality of life. As such, patient selection crucial to its success.
