1. Watch and Wait, Worth It?
Abstract Background The surgery with total mesorectal excision recommended by R. J. Heald in 1982 is the gold standard. Rectal cancer (RC) surgery has a morbidity rate ranging from 6 to 35%, and it can cause functional issues such as sexual, urinary, and bowel dysfunction in the long term. Neoadjuvant chemoradiotherapy (CRT) has been gaining ground in patie

2. Impact of the Vertical Division of the Rectum on the Decrease in Reloading of the Endostapler for a Complete Division in Colorectal Cancer
Abstract Background Despite several improvements in surgical techniques, the intracorporeal division of the distal end of the rectum is still challenging, particularly when it is too deep in a narrow pelvis. Even though it helps avoid spillage, the double-stapling technique (DST) raises concerns regarding safety and anastomotic leakage if multiple stapler f

3. McKittrick-Wheelock Syndrome Secondary to Rectal Adenocarcinoma
ABSTRACT Introduction McKittrick-Wheelock syndrome is a rare condition that arises from a hypersecretory state secondary to large colorectal tumors, mainly villous adenomas, leading to an electrolytic disorder associated with chronic diarrhea that usually persists for years. It is a relatively unknown disease that can lead to severe complications such as ac

4. Therapeutics in Radiation-induced Proctopathy: A Systematic Review
Abstract Malignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to min

5. Tissue Factor Expression in Colorectal Adenocarcinoma: Association with Angiogenesis and Clinical and Pathological Aspects
Abstract Introduction Tissue factor (TF) expression has been described in various neoplasms and was correlated with angiogenesis and metastases. Objectives To describe TF expression in colorectal cancers, correlating it with microvessel density and clinical and pathological variables. Methods Immunohistochemistry was used to determine TF expression and

6. Can Fecal Calprotectin Reflect Your Colonic Status?
Abstract Background Organic colonic manifestation may be difficult to be differentiated from functional one. Inflammatory bowel disease (IBD) is a common chronic inflammatory and destructive disease of the bowel wall. Chronic inflammation is associated with ulcerations, strictures, perforations, and it is a risk factor for dysplasia and cancer. To reduce t

7. Long-term results from modified sphincteroplasty in patients with traumatic sphincter injury: a retrospective study
ABSTRACT BACKGROUND: The results from sphincteroplasty may worsen over time. Reseparation of the rectum and vagina/scrotum in conjunction with sphincteroplasty achieves good results. Improving the surgical effect of sphincteroplasty through perineal body reconstruction is crucial. OBJECTIVE: To evaluate the long-term results from anterior sphincteroplast

8. Comparison of pain levels in fusion prostate biopsy and standard TRUS-Guided biopsy
ABSTRACT Objectives Fusion prostate biopsy (FPB) has recently emerged as a popular and successful biopsy technique on diagnosis of prostate cancer. The aim of this study was to compare the pain levels in TRUS-guided standard 12-core prostate biopsy (SPB) and MpMRI-guided FPB. Materials and Methods Patients detected with a PI-RADS (Prostate Imaging Report

9. Robotic conservative treatment for prostatourethrorectal fistula: original technique step by step
ABSTRACT Purpose: Prostatourethrorectal fistula (PURF) is an uncommon complication resulting from surgery, radiation or trauma (1). The most common therapeutic management is transperineal surgery (1). Transabdominal approach is less used and limited to large fistulae needing cystectomy and rectal resection (1). The aim of this study was to show an original

10. IS SUPERFICIAL COLORECTAL LESIONS WITH LOW AND HIGH GRADES INTRAEPITHELIAL NEOPLASMS MORE PREVALENT IN OLDER ABOVE 65 YEARS?
RESUMO Racional: O câncer colorretal tem maior incidência no reto e sigmoide. Porém, com a ampliação do diagnóstico das lesões superficiais do cólon e reto tem-se aumentado o interesse por elas no diagnóstico e no papel que elas representam na carcinogênese colorretal. Objetivo: Verificar o comportamento das lesões superficiais do cólon e reto,

12. Extracellular vesicles isolated from Trypanosoma cruzi affect early parasite migration in the gut of Rhodnius prolixus but not in Triatoma infestans
The protozoan Trypanosoma cruzi has the ability to spontaneously secrete extracellular vesicles (EVs). In this paper, T. cruzi EVs derived from epimastigote forms were evaluated during interaction with triatomine bugs Rhodnius prolixus and Triatoma infestans. T. cruzi EVs were purified and artificially offered to the insects prior to infection with epimastig
