PURPOSE Although rectal cancer is a very common malignancy and has an improved cure rate in response to oncological treatment, research on rectal-cancer survivors' sexual function remains limited. Sexual dysfunction (SD) after rectal cancer treatment was measured, and possible predisposing factors that may have an impact on the development of this disorder were identified. METHODS Patients un...

Overt rectal bleeding is a common symptom of colorectal cancer and polyps but also occurs in apparently healthy people. It is not known how often this represents bleeding from an undiagnosed rectal or sigmoid polyp or cancer. Three hundred and nineteen apparently healthy men aged over 50, selected by random sampling, were interviewed and underwent flexible sigmoidoscopy to at least 30 cm. Polyp...

Children find a rectal examination unpleasant and over a third experienced severe discomfort in this study. This is acceptable only if essential information affecting management is obtained. In this series, the diagnosis of acute appendicitis in over 90% of cases was made from the clinical history and abdominal examination. In two cases the rectal tenderness indicated the correct diagnosis. Rec...

INTRODUCTION HIV infection continues to disproportionately affect men who have sex with men (MSM). Identification of modifiable risk factors for HIV infection among MSM is critical for effective prevention. METHODS We examined the relationship between number of prior rectal Neisseria gonorrhoeae (GC) or Chlamydia trachomatis (CT) infections and HIV seroconversion in a retrospective cohort of ...

Background Anal sphincter tone is routinely assessed by digital rectal examination in patients with fecal incontinence, although its accuracy in detecting sphincter defects or separating competent from incompetent muscles has not been established. Objective In this setting, we aimed to evaluate the accuracy of digital rectal examination in grading anal defects in order to separate small from ...

OBJECTIVE Sexual transmission of HIV occurs across a mucosal surface, which contains many soluble immune factors important for HIV immunity. Although the composition of mucosal fluids in the vaginal and oral compartments has been studied extensively, the knowledge of the expression of these factors in the rectal mucosa has been understudied and is very limited. This has particular relevance giv...

Our objective was to determine the diagnostic accuracy of a free-breathing diffusion-weighted single-shot echo-planar magnetic resonance imaging (FBDW-SSEPI) technique with parallel imaging and high diffusion factor value (b = 1000 s/mm2) in the detection of primary rectal adenocarcinomas. Thirty-one patients (14M and 17F; mean age 67 years) with histopathologically proven primary rectal adenoc...

BACKGROUND Prostate cancer involving the rectal wall is rare and may lead to diagnostic pitfalls. CASE PRESENTATION Out of 9504 patients with rectal tumors between January 2003 and January 2015, 9 patients (elderly with a mean age of 74 years) with prostate cancer involving the rectal wall were clinically misdiagnosed with rectal cancer. The lesions were located in the rectum, and included 3 ...

BACKGROUND Treating prostate cancer with SBRT could potentially minimize radiation proctitis by reducing high-dose rectal irradiation. In addition, it offers the potential radiobiologic benefits of hypofractionation. This study reports the endoscopic changes and the associated clinical rectal toxicity in these patients. METHODS We reviewed the records of patients treated from 2008-2011 for lo...

PURPOSE To evaluate association between equivalent dose in 2 Gy (EQD2) to rectal point dose and gastrointestinal toxicity from whole pelvic radiotherapy (WPRT) and intracavitary brachytherapy (ICBT) in cervical cancer patients who were evaluated by rectosigmoidoscopy in Faculty of Medicine, Chiang Mai University. MATERIALS AND METHODS Retrospective study was designed for the patients with loc...
