Management Of Rectal Bleeding Research Articles

Rectal bleeding

This article aims to cover the presentation and management of rectal bleeding in adults, in sufficient breadth and depth for the GP trainee, recently qualified GPs, GP trainers and other allied health professionals consulting with patients in primary care. Rectal bleeding is a common reason for patients to consult their GP, urgent care centre or emergency department. The aetiology and variable presentations can pose a significant challenge to the primary care clinician. We hope this article will refresh background understanding and guide the assessment and management of these patients.

Evaluation and management of rectal bleeding in pregnancy.

Rectal bleeding occurs in about 40% of pregnant women, and is predominantly attributed to benign perianal pathology (haemorrhoids or anal fissures). More sinister causes of rectal bleeding may be heralded by key red flag clinical and biochemical features. These features should be evaluated in all women with rectal bleeding. Imaging investigations or flexible sigmoidoscopy may be warranted. The latter can be performed safely by experienced operators in pregnant women. Women with evidence of haemodynamic compromise, elevated inflammatory markers, significant anaemia, signs of intestinal obstruction or compromise to the fetus should be evaluated urgently. Providers must be mindful of the changes in normal ranges for common haematological and biochemical parameters in pregnancy compared with the non-pregnant state. Faecal calprotectin is an established tool for identification of intestinal inflammation and is valid in pregnancy. An elevated faecal calprotectin level (≥50µg/g) signifies a need for further diagnostic evaluation. Inflammatory bowel disease may present initially, or with worsening disease activity, in pregnancy. Expedient diagnosis with the use of faecal calprotectin, sigmoidoscopy with or without intestinal ultrasound, exclusion of alternative or compounding infective aetiologies, and institution of appropriate therapy are critical. Medical therapies for management of inflammatory bowel disease can be safely instituted in pregnancy. Colorectal cancer incidence is increasing in younger age groups, but fortunately remains rare. When diagnosed in pregnancy, colorectal cancer can be successfully and safely managed with a collaborative multidisciplinary team approach. Early diagnosis is key to optimising outcomes.

Lower gastrointestinal bleeding in pregnancy: Differential diagnosis, assessment and management.

Rectal bleeding is a common symptom experienced by pregnant women. Although the majority of cases are attributable to benign conditions such as haemorrhoids and anal fissures, other more serious diagnoses such as inflammatory bowel disease and malignancy should not be overlooked. Most investigations are safe during pregnancy and these should not be withheld as significant implications on both fetal and maternal morbidity may result. In these cases, a multidisciplinary team approach is essential. This review explores the differential diagnosis, investigation and management of rectal bleeding during pregnancy.

The management of rectal bleeding following transrectal prostate biopsy: A review of the current literature.

Since the advent of prostate-specific antigen (PSA)-based testing, transrectal ultrasound (TRUS)-guided prostate biopsy has become a standard part of the diagnostic pathway for prostate cancer (PCa). Rectal bleeding is one of the common side effects of this transrectal route. While rectal bleeding is usually mild and self-limiting, it can be life-threatening. In this article, we examine rectal bleeding post-TRUS-guided prostate biopsy and explore the literature to evaluate techniques and strategies aimed at preventing and managing this common and important complication. A PubMed literature search was carried out using the keywords "transrectal-prostate-biopsy-bleed." A search of the bibliography of reviewed studies was also conducted. Additionally, papers in non-PubMed-listed journals of which the authors were aware were appraised. Numerous modifiable risk factors for this bleeding complication exist, particularly anticoagulants/antiplatelets and the number of core biopsies taken. Successfully described corrective measures for such rectal bleeding include tamponade (digital/packs/catheter/tampon/condom), endoscopic sclerotherapy/banding/clipping, radiological embolization, and surgical intervention. We advocate early consultation with the colorectal/gastroenterology and interventional radiology services and a progressive, stepwise approach to the management of post-biopsy rectal bleeding, starting with resuscitation and conservative tamponade measures, moving to endoscopic hemostasis ± radiological embolization ± transanal surgical methods. Given the infrequent but serious nature of major rectal bleeding after TRUS biopsy, we recommend the establishment of centralized databases or registries forthwith to prospectively capture such data. To the best of our knowledge, this is the first comprehensive look specifically at the management of post-TRUS biopsy rectal bleeding.

The management of rectal bleeding in the military population

AbstractRectal bleeding continues to be a common ailment, with the clear majority associated with benign conditions. The deployed environment provides both a diagnostic and in some cases, therapeutic challenge. This paper aims to highlight the key differences between benign and sinister pathologies, and their management in the Role 1 environment.

Ozone Therapy in the Management of Persistent Radiation-Induced Rectal Bleeding in Prostate Cancer Patients.

Introduction. Persistent radiation-induced proctitis and rectal bleeding are debilitating complications with limited therapeutic options. We present our experience with ozone therapy in the management of such refractory rectal bleeding. Methods. Patients (n = 12) previously irradiated for prostate cancer with persistent or severe rectal bleeding without response to conventional treatment were enrolled to receive ozone therapy via rectal insufflations and/or topical application of ozonized-oil. Ten (83%) patients had Grade 3 or Grade 4 toxicity. Median follow-up after ozone therapy was 104 months (range: 52–119). Results. Following ozone therapy, the median grade of toxicity improved from 3 to 1 (p < 0.001) and the number of endoscopy treatments from 37 to 4 (p = 0.032). Hemoglobin levels changed from 11.1 (7–14) g/dL to 13 (10–15) g/dL, before and after ozone therapy, respectively (p = 0.008). Ozone therapy was well tolerated and no adverse effects were noted, except soft and temporary flatulence for some hours after each session. Conclusions. Ozone therapy was effective in radiation-induced rectal bleeding in prostate cancer patients without serious adverse events. It proved useful in the management of rectal bleeding and merits further evaluation.

Hemorrhoid management in patients with radiation proctitis

Management of rectal bleeding in patients with radiation proctitis presents a conundrum for practitioners. Surgeons are appropriately concerned about using conventional methods of treatment in these patients, such as cautery for bleeding areas in the rectum, rubber band ligation, or excision of internal and/or external hemorrhoids, for fear of poor healing and possible exacerbation of the original problem. Few randomized controlled trials are available on the treatment of radiation proctitis alone, and no literature exists pertaining to the management of symptomatic hemorrhoids in the radiated patient. In the absence of observational studies, the authors created an email survey to distribute to the membership of the American Society of Colon and Rectal Surgeons in order to try to identify current management practices for radiation proctitis and for the treatment of their symptomatic hemorrhoids. Of the 327 respondents, 85% favored the use of topical formalin to treat radiation proctitis, while 42% additionally used argon plasma coagulation. Only 25% of practitioners report using sucralfate, though existing data on this therapy are promising. Regarding the management of hemorrhoids in patients with a history of rectal irradiation, 55% of respondents hoped treatment of radiation proctitis alone would solve the problem. Forty-three percent reported using rubber band ligation, 30% using hemorrhoidectomy, and 18% using sclerotherapy. While most respondents treated radiation proctitis alone in patients with symptomatic hemorrhoids, many also felt rubber band ligation, hemorrhoidectomy, and sclerotherapy are safe and effective alternative therapies in this population.

Sigmoidoscopy in children with chronic lower gastrointestinal bleeding.

This study was done to assess the role of rigid sigmoidoscopy in diagnosis and prognosis of children with chronic and minor lower gastrointestinal bleeding. Retrospective review of the clinical notes of children under 15 years of age with minor and chronic lower gastrointestinal bleeding who had rigid sigmoidoscopy and biopsy between October 1998 and April 2002 at Liaquat Medical College Hospital, Hyderabad, Pakistan. Demographic data, clinical presentation, morbidity, sigmoidoscopic and histopathological findings were analysed to determine the role of rigid sigmoidoscopy in the management of rectal bleeding in children. A total of 229 sigmoidoscopic examinations were carried out in 207 children with a mean age of 6 years. Seventy-seven per cent (160) of children were symptomatic for a year or more. Causes of bleeding were juvenile colorectal polyps (155 cases; 75%), non-specific proctitis (38 cases; 18%), solitary rectal ulcer (seven cases; 3.5%), lymphoid nodular hyperplasia (six cases, 3%) and foreign body (betel nuts) impaction (one case; 0.5%). Polyps were mostly in the rectosigmoid region and solitary in 136 (88%) children. All polyps were removed by rigid sigmoidoscopy. Histological examination of 137 polyps revealed juvenile type in 136 (99%) cases and low-grade dysplastic changes in one patient. Non-specific proctitis (n = 38) was confirmed histologically in 92% (n = 35) of cases and it was self-limiting in 86% of cases. Other findings include solitary rectal ulcer in seven, lymphoid nodular hyperplasia in six and telangiectasic (pyogenic) granuloma in one patient. Rigid sigmoidoscopy was useful in diagnosis, treatment and prognostic evaluation of children with chronic and minor lower gastrointestinal bleeding. Final diagnosis was confirmed by histopathology.

Hydrosonography in the evaluation of colorectal polyps.

Prewarmed saline enemas and transabdominal ultrasound (hydrosonography) were used to evaluate 17 consecutive children with rectal bleeding before colonoscopy. Twelve patients with polyps were identified (10 by ultrasound, 10 by endoscopy): these included multiple hyperplastic polyps (1), multiple polyps (1), solitary polyps (9), and pseudopolyps (1). Ultrasound identified 11 polyps in 10 patients, missing two patients with small polyps less than 0.5 cm in diameter. The polyps were hyperechoic ovoid masses fixed to the colonic wall, with a stalk (7), submucosal infolding (5), and intraluminal floating (5). There was one false positive. Colonoscopy was refused by one patient and failed to reach beyond the distal sigmoid in another following previous surgery for malrotation. Colonoscopy was superior in identifying finer mucosal detail (colitis, ulcers, proctitis, anal fissure) and in detecting smaller polyps (sessile polyps, hyperplastic polyps). Hydrosonography of the colon is a simple, relatively non-invasive procedure that provides an alternative, radiation-free examination of the whole colon before colonoscopy. It is complementary to colonoscopy in the management of rectal bleeding in children.

The child with rectal bleeding

Although the causes of rectal bleeding in the paediatric age group are legion, a few relatively common diagnoses account for the majority, and in contrast to the adult situation, rectal bleeding presaging malignancy is rare. ’ The first step in the management of rectal bleeding is to recognize that most causes are broadly age related, hence the child should be considered in one of the following age groups;2 (i) Newborn, up to 1 month, (ii) Infant, from 1 month to 1 year, (iii) Child, from 1 to 12 years, (iv) Adolescent. A sound history and examination may often be diagnostic, although special attention to the following factors is especially useful.

A retrospective study on the management of rectal bleeding.

This paper reports on a retrospective study of 70 patients who were admitted to the Royal Adelaide Hospital with rectal bleeding. The study demonstrates several points; first, that there are two distinct groups of patients. The majority of patients had minor bleeds that ceased spontaneously. The remaining group of patients (12%) had what could be described as massive rectal bleeds. There was also noted to be a significant number of patients (21%) who were discharged with no final diagnosis. The utilization of investigations such as angiography and nuclear medicine scans was minimal. The paper concludes that there is a need to establish a protocol for the management of rectal bleeding and, if diagnostic yield is to be satisfactory, energetic attempts must be made to commence investigations at presentation, as soon as resuscitative measures are in progress.

Colonoscopic Diagnosis and Management of Rectal Bleeding

The use of the colonoscope to evaluate the cause of rectal bleeding in a series of 2200 patients has been reviewed. The most common cause of bleeding in this series was found to be neoplastic polyps, which were present in 723 patients (32 per cent). Colonic carcinoma was detected as the source of the bleeding in 425 cases (19 per cent). Although a large number of barium enema films were false negatives, the patients reviewed are a highly select group. It is still believed that barium enema studies and colonoscopy are complementary rather than competitive procedures. Their continued combined use greatly enhances diagnostic accuracy. Various other causes of colonic bleeding, including inflammatory bowel disease, arteriovenous malformations, endometriosis, ovarian carcinoma, ischemic colitis, and radiation colitis, have been discussed and their endoscopic appearance described. Of particular significance is the coexistence of internal hemorrhoids or diverticular disease and neoplastic colonic lesions. Barium enema films and sigmoidoscopy have been frequently described as the twin pillars of diagnosis in the detection of colonic pathology. Colonoscopy, as the third pillar of diagnosis, should be an integral part of the evaluation of patients with rectal bleeding.
