  • High Quality Fecal Occult Blood Testing (FOBT) for CRC Screening: Evidence and Recommendations
    High Quality Fecal Occult Blood Testing (FOBT) for CRC Screening: Evidence and Recommendations Rationale for use of FOBT High sensitivity fecal occult blood testing (FOBT) is one of the colorectal cancer screening methods recommended in guidelines from the American Cancer Society, the US Preventive Services Taskforce, and every other major medical organization. In spite of this widespread endorsement, primary care clinicians often express conviction that colonoscopy is the “gold standard” test for colorectal cancer screening and that the use of FOBT represents sub-standard care. These beliefs persist in spite of well-documented shortcomings of endoscopy (missed adenomas and cancers, higher complication rates and higher one-time costs than other screening methodologies), and the fact that access to endoscopy is limited or non- existent for a significant proportion of the U.S. population. Many clinicians are also unaware that randomized controlled trials of FOBT screening have demonstrated decreases in colorectal cancer incidence and mortality, and modeling studies suggest that the years of life saved through a high quality FOBT screening program are essentially the same as with a high quality colonoscopy based screening programs. Recent advances in stool blood screening include the emergence of new tests and improved understanding of the impact of quality factors on testing outcomes. This document provides state-of-the-science information about high quality stool testing. Types of Fecal Occult Blood Tests Two main types of FOBT are available – guaiac and immunochemical. Both types of FOBT have been shown to have reasonably high detection rates for colon and rectal cancers; adenoma detection rates are appreciably lower.

  • Colorectal Cancer
    Colorectal Cancer Colorectal cancer is the second most common cancer in the United States, striking 140,000 people annually and causing 60,000 deaths. That’s a staggering figure when you consider the disease is potentially curable if diagnosed in the early stages. Who is at risk? Though colorectal cancer may occur at any age, more than 90% of the patients are over age 40, at which point the risk doubles every ten years. In addition to age, other high risk factors include a family history of colorectal cancer and polyps and a personal history of ulcerative colitis, colon polyps or cancer of other organs, especially of the breast or uterus. How does it start? It is generally agreed that nearly all colon and rectal cancer begins in benign polyps. These pre-malignant growths occur on the bowel wall and may eventually increase in size and become cancer. Removal of benign polyps is one aspect of preventive medicine that really works! What are the symptoms? The most common symptoms are rectal bleeding and changes in bowel habits, such as constipation or diarrhea. (These symptoms are also common in other diseases so it is important you receive a thorough examination should you experience them.) Abdominal pain and weight loss are usually late symptoms indicating possible extensive disease. Unfortunately, many polyps and early cancers fail to produce symptoms. Therefore, it is important that your routine physical includes colorectal cancer detection procedures once you reach age 50. There are several methods for detection of colorectal cancer. These include digital rectal examination, a chemical test of the stool for blood, flexible sigmoidoscopy and colonoscopy (lighted tubular instruments used to inspect the lower bowel) and barium enema.

  • Benefit of Rectal Examination in Children with Acute Abdomen
    Benefit of Rectal Examination in Children with Acute Abdomen Wasun Nuntasunti MD*, Mongkol Laohapensang MD** * Department of Surgery, Sisaket Hospital, Sisaket, Thailand ** Department of Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand Background: Acute abdomen is a condition that often mandates urgent treatment. PR or DRE (per rectal examination or digital rectal examination) is one of the fundamental physical examinations that doctors use to differentiate causes of acute abdominal pain. However, it is not a pleasant examination to undergo. Sometimes doctors ignore this examination. The benefit of per rectal examination has rarely been studied in children. Objective: This study was designed to demonstrate the benefit of rectal examination for contribution to the diagnosis of acute abdominal pain in children and reduction of unnecessary operation. Material and Method: A prospective cross sectional study of children ages 3 to 15 years old who presented with acute abdominal pain from January 2012 to December 2013 was conducted. The clinical parameters including DRE results were correlated to the diagnosis. The diagnoses prior to and after DRE were compared. The accuracy of DRE was analyzed by pair response analysis of pre and post-DRE results using McNemar‘s Chi-square test. Results: A total of 116 children with acute abdominal pain were enrolled in the study. The final diagnoses were appendicitis accounting for 27%, constipation 28%, non-surgical gastrointestinal diseases such as gastritis, diarrhea and food poisoning 9%, diseases of the female reproductive system 7% and others 29%. In comparing the diagnoses prior to and after digital rectal examination, it was demonstrated that rectal examination significantly helped differentiate diagnosis in 38.8% of patients, whereas 19% of the patients gained no benefit.DRE corrected the diagnosis in 45 cases which was significantly higher than misguiding the diagnosis in 3 cases.

Abstract: Background: Digital rectal examination (DRE) is considered an important part of the physical examination. However, it is unclear how many patients have a DRE performed at the primary care level in the work-up of rectal cancer, and if the absence of a DRE causes a delay to consultation with a specialist. Methods: A retrospective patient questionnaire was sent to 1000 consecutive patients with stage II or stage III rectal cancer. The questionnaire asked patients to recall if they had a DRE performed by their general practitioner (GP) when they first presented with symptoms or a positive FIT test. Demographic data, staging data, and time to consultation with a specialist were also Citation: Farooq, O.; Farooq, A.; collected.

Abstract Background Colorectal resection anastomosis is the commonest cause of rectal strictures. Anastomotic site ischemia, incomplete doughnuts from stapled anastomo- sis and pelvic infection, are some of the risk factors that play a role in the development of postoperative rectal strictures. However, the role of diverting stoma in the development of rectal strictures has not been studied extensively. Objectives To study the difference in the occurrence of anastomotic strictures (AS) in patients submitted to low anterior resection (LAR) with covering ileostomy (CI), and to LAR without CI for carcinoma rectum. Methods This was a prospective, comparative case control study carried out at a tertiary care referral center. Low anterior resection with covering ileostomy was performed in patients with rectum carcinoma in the study group, while LAR without covering ileostomy was performed in the control group. The study group had 29 patients, while the control group had 33 patients with rectum carcinoma.

Medical College, Bhavnagar, Gujarat, India For correspondence: Ashish Bhanot, C-7 Doctors Quarters, Sir T. Hospital Campus, Bhavnagar - 364 001, Gujarat, India. E-mail: [email protected] ABSTRACT ‘Foreign’ means originating elsewhere or simply ‘outside the body.’ Foreign body rectum is not as common as other parts of the body. Rectal foreign bodies present are difficult to manage. Emergency-department Case Report procedures include rectal examination, proctoscopy and abdominal radiography. Soft or low-lying objects having an edge could be grasped and removed safely in the emergency department, but grasping hard objects is potentially traumatic and occasionally results in upward migration toward the sigmoid. Although foreign bodies can be removed in the emergency department in about two out of three cases, some 10% still require a laparotomy and a diverting colostomy to remove the object or to treat bowel perforation. We are presenting a case of laparoscopic assisted removal of tumbler using 10 mm suction cannula to push the object down. Laparoscopy helped not only in retrieval but also enabled visualizing any bowel perforation due to foreign body and its manipulation.

  • Rectal Invasion by Metastatic Prostate Adenocarcinoma
    Open Access Case Report DOI: 10.7759/cureus.15569 Rectal Invasion by Metastatic Prostate Adenocarcinoma Anshu Wadehra 1 , Samer Alkassis 1 , Aliza Rizwan 1 , Omid Yazdanpanah 1 1. Internal Medicine, Wayne State University/Detroit Medical Center, Detroit, USA Corresponding author: Anshu Wadehra, [email protected] Abstract In men, prostate cancer is the second most diagnosed cancer worldwide. Typical sites for metastasis include bone, lung, and liver. Prostate cancer with gastrointestinal involvement, particularly rectal, has been rarely reported in the literature. As patients with prostate cancer with rectal invasion may present with symptoms similar to those of other gastrointestinal pathologies, such as anal fissures and rectal carcinoma itself, misdiagnosis and delays in care can result. Direct visualization of the rectum via endoscopy, along with biopsy, allows clinicians to make an accurate and timely diagnosis in patients with prostate cancer with rectal involvement, which in turn leads to broader available treatment options. Categories: Gastroenterology, Oncology Keywords: prostate cancer, rectal mass, rectal metastasis, rectal pain, sigmoidoscopy Introduction Prostate cancer is the second most common cancer in men worldwide [1]. Although localized disease is the most common finding at the time of diagnosis, some patients have evidence of metastatic prostate cancer at presentation. The most frequent location of metastasis is bone, particularly the axial skeleton, followed by lung and liver [2]. Gastrointestinal, especially rectal, involvement by prostate cancer has been rarely reported in the literature [3]. Invasion to the rectum occurs through three proposed routes; either direct invasion through the fascia, lymphatic spreading, or iatrogenic seeding of cancer cells during transrectal biopsy [4].
