[Low diagnostic accuracy of rigid sigmoidoscopy in the investigation of rectal cancer].

Lakartidningen 2020 04 20;117. Epub 2020 Apr 20.

.

We performed a retrospective observational study to investigate the diagnostic accuracy of rigid sigmoidoscopy (RS) in patients with rectal cancer (n=279). Fifty-six percent of the patients had performed an RS within three months before diagnosis and mostly by a primary care provider (93%). In 21% of the patients the physician determined that the examination was normal, in 50% a rectal tumor was suspected and in 29% of cases an unspecific pathology (e. Read More

Contemporary management of rectal trauma - A South African experience.

Injury 2020 May 24;51(5):1238-1241. Epub 2020 Feb 24.

Department of Surgery, University of the Witwatersrand, Johannesburg, South Africa; Department of Surgery, University of KwaZulu Natal, Durban, South Africa. Electronic address:

Introduction: The management of rectal trauma remains controversial.

Computed tomography and magnetic resonance imaging findings of metastatic rectal linitis plastica from prostate cancer: A case report and review of literature.

World J Clin Cases 2018 Oct;6(12):554-558

Department of Surgery, Chonbuk National University Medical School and Hospital, Jeonju 54907, Chonbuk, South Korea.

Linitis plastica is a rare condition showing circumferentially infiltrating intramural anaplastic carcinoma in a hollow viscus, resulting in a tissue thickening of the involved organ as constricted, inelastic, and rigid. While most secondary rectal linitis plastica (RLP) is caused by metastasis from stomach, breast, gallbladder, or bladder cancer, we report an extremely rare and unique case of secondary RLP due to prostate cancer with computed tomography (CT) and magnetic resonance imaging (MRI) findings, including diffusion weighted imaging (DWI). A 78-year-old man presented with approximately a 2-mo history of constipation and without cancer history. Read More

J Int AIDS Soc 2018 10;21(10):e25199

Division of Infectious Diseases, Department of Medicine, The Hope Clinic of the Emory Vaccine Center, Emory University School of Medicine, Atlanta, GA, USA.

Introduction: Oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) is highly effective in preventing HIV infection among men who have sex with men (MSM). The effects of consistent personal lubricant use in the rectum on tissue PrEP drug concentrations and the rectal microbiota are unknown. We investigated rectal PrEP drug concentrations and the microbiota in MSM before and after repeated rectal application of a hyperosmolar lubricant. Read More

Anal and Perineal Injuries.

Clin Colon Rectal Surg 2018 Jan 19;31(1):24-29. Epub 2017 Dec 19.

Division of Colon and Rectal Surgery, Department of Surgery, University of Pennsylvania, Philadelphia, Pennsylvania.

With increased use of explosive devices in warfare, anal trauma is often seen coupled with more complex pelviperineal injury. While the associated mortality is high, casualties that survive are often left with disabling fecal incontinence from damage to the anosphincteric complex. After resolution of the acute insult, the initial evaluation mandates a thorough physical exam, including endoscopic evaluation with rigid proctoscopy and flexible sigmoidoscopy, as well as adjunctive testing, specifically anal manometry and endoanal ultrasound.

BMC Health Serv Res 2015 Feb 1;15:51. Epub 2015 Feb 1.

Department of Family and Community Medicine, St. Michael's Hospital and University of Toronto, Toronto, ON, Canada.

Background: Because of the increased life-expectancy of persons with HIV, the need for age-appropriate colorectal cancer screening among these patients will increase. We examined rates of colorectal cancer screening among HIV-infected men aged 50 to 65 years.

Methods: We used Ontario's administrative databases to identify all men between the ages of 50 and 65 years who were alive on April 1, 2007, and identified HIV-infected men using a validated case-finding algorithm. Read More

Patients newly diagnosed with ulcerative colitis receive earlier treatment in surgical clinics.

Colorectal Dis 2013 Jul;15(7):836-41

Department of Colorectal Surgery, Queen Elizabeth Hospital, Birmingham, UK.

Aim: The diagnosis and treatment of ulcerative colitis (UC) is traditionally the realm of gastroenterologists. However, the symptoms of UC overlap with those of bowel cancer and patients may be initially referred to colorectal surgery clinics. The aims of this study were to define which specialty most frequently diagnoses UC and to determine if there were differences in management between the two specialities. Read More

Surgical vs general practitioner assessment: diagnostic accuracy in 2-week-wait colorectal cancer referrals.

Colorectal Dis 2011 Aug;13(8):e212-5

Department of Surgery and Cancer, Imperial College London, St. Mary's Hospital, London, UK.

Aim: It has been recommended that patients with suspected colorectal cancer should proceed straight to an endoscopic test to increase speed of diagnosis, using only the information in the general practitioner's referral letter. This study aims to establish whether the diagnostic accuracy of the first surgical outpatient assessment is significantly greater than the general practitioner's assessment and if so by what means.

Method: Demographic variables, symptoms and signs were collected from the first surgical outpatient assessment letters and the general practitioners' referral letters in 2-week-wait colorectal cancer referrals made between 2002 and 2005. Read More
