Acute Lower Gastrointestinal Tract Bleeding. IN: Wexner, S.; Stollman, N., eds. Diseases of the Colon. . New York, NY: Informa Healthcare USA. 2007. pp 363-374.

This chapter about acute lower gastrointestinal (GI) bleeding is from a comprehensive text that offers chapters about each of the major colonic disorders. Each chapter is coauthored by at least one surgeon and one gastroenterologist to reflect the in-depth collaboration between these fields that is required for managing diseases of the colon. In this chapter, the authors cover clinical classification, differential diagnosis, specific causes of lower GI tract bleeding, management of acute lower GI tract bleeding, and anticipated outcomes. They stress that severe acute lower GI tract bleeding is associated with unstable vital signs, rapidly developing anemia, and a possible need for transfusion. Types of GI bleeding include low-volume and high-volume hematochezia, melena, occult GI bleeding, and pseudobleeding. Specific causes of lower GI tract bleeding include diverticulosis, angiodysplasia and vascular ectasia, Dieulafoy lesions, colonic varices, Meckel’s diverticulum, postpolypectomy bleeding, colitis, ulcers, neoplasia, endometriosis, and aortoenteric fistula. The risk of mortality in acute lower GI bleeding increases with age, transfusion requirements, comorbid conditions, and the frequency of rebleeding. 2 tables. 44 references.

Benign Prostatic Hyperplasia, Bladder Neck Obstruction, and Prostatitis. IN: Atlas of Urodynamics. 2nd ed. Williston, VT: Blackwell Publishing Inc. 2007. pp 96-119.

The purpose of urodynamic testing is to measure and record various physiological variables while the patient is experiencing those symptoms which make up the presenting complaint. This chapter on benign prostatic hyperplasia (BPH), bladder neck obstruction, and prostatitis is from an atlas of urodynamics that provides a comprehensive, detailed look at the indications, technology, and use of urodynamics in modern urologic practice. The chapter begins with a section defining the terminology currently in use, then goes on to cover mechanical obstruction, smooth muscle obstruction, differential diagnosis, urodynamic evaluation, primary bladder neck obstruction, acquired voiding dysfunction, bladder diverticula, the neurogenic bladder and BPH, and chronic pelvic pain syndrome and prostatitis. The authors then present case illustrations, accompanied by figures and black-and-white photographs of actual urodynamic tests. The authors note that, even in patients with documented prostatic obstruction, factors other than the mechanical effects of prostatic bulk play an important role. These include detrusor muscle strength and tone, bladder wall compliance, smooth muscle function of the bladder neck and prostatic urethra, striated muscle function of the prostate-membranous urethra, and interstitial factors such as elastin and collagen type. 18 figures. 1 table. 15 references.

Bladder Outlet Obstruction and Impaired Detrusor Contractility in Women. IN: Atlas of Urodynamics.2nd ed. Williston, VT: Blackwell Publishing Inc. 2007. pp 120-144.

The purpose of urodynamic testing is to measure and record various physiological variables while the patient is experiencing those symptoms which make up the presenting complaint. This chapter on bladder outlet obstruction and impaired detrusor contractility in women is from an atlas of urodynamics that provides a comprehensive, detailed look at the indications, technology, and use of urodynamics in modern urologic practice. The chapter begins with a section on etiology and diagnosis, then present cases illustrations, accompanied by figures and black-and-white photographs of actual urodynamic tests. The authors note that urethral obstruction can be caused by prior surgery, prolapse, stricture, primary bladder neck obstruction, detrusor external sphincter dyssynergia (DESD), acquired voiding dysfunction, or urethral diverticulum; the two most common causes of genital prolapse and complications after anti-incontinence operations. From a urodynamic standpoint, the diagnosis of impaired detrusor contractility is characterized by a low flow and low detrusor pressure. 21 figures. 2 tables. 27 references.

Diverticular Disease. IN: Wexner, S.; Stollman, N., eds. Diseases of the Colon. . New York, NY: Informa Healthcare USA. 2007. pp 399-434.

This chapter about diverticular disease is from a comprehensive text that offers chapters about each of the major colonic disorders. Each chapter is coauthored by at least one surgeon and one gastroenterologist to reflect the in-depth collaboration between these fields that is required for managing diseases of the colon. In this chapter, the authors cover historical aspects, epidemiology, natural history, pathologic anatomy, etiology and pathogenesis, uncomplicated diverticulosis, complicated diverticular disease, and hemorrhage associated with diverticular disease. They note that most people with diverticulosis are asymptomatic, which makes the pathogenesis and natural history of diverticular disease somewhat difficult to study. Particular emphasis is placed on the role of colonoscopy in the diagnosis and management of diverticular disease and on the emerging role of minimally invasive surgical management of diverticular complications. Dietary fiber may play a preventive role and should be recommended to those patients with asymptomatic or mild disease. Medical management of diverticulitis involves a combination of antibiotics and, when necessary, percutaneous drainage. Surgery is used electively after multiple attacks of diverticulitis and more urgently for complications such as abscess, free perforation, fistula, or obstruction. A patient care algorithm is provided. The chapter includes black-and-white photographs and illustrations and concludes with an extensive list of references. 11 figures. 3 tables. 211 references.

Diverticular Disease: Evidence for Dietary Intervention?. Practical Gastroenterology. 31(2): 38-46. February 2007.

This review considers the present evidence supporting the hypothesis that a low-fiber diet is responsible for rising trends in the incidence of diverticular disease and its complications. In addition, a high-fiber diet is thought to prevent the occurrence of symptoms in patients with diverticular disease. The author notes that most of the evidence for a causal relationship is based on observational, uncontrolled studies, and that evidence from the only two randomized controlled trials conducted to test this hypothesis is inconsistent. However, the findings from the epidemiologic observational studies have been consistent and are based on a plausible biologic explanation. The author concludes that more research is needed to test these hypotheses regarding the interplay between dietary fiber and diverticulosis. 18 references.
