Cloacal Prolapse in Raptors: Review of 16 Cases

Sixteen cases of cloacal prolapse in raptors were reviewed in this study. Colonic prolapse was the most common presentation (56% of cases). Red-tailed hawks ( Buteo jamaicensis ) were overrepresented, comprising 66% of colonic prolapse cases. In cases of colonic prolapse, postsurgical stricture formation was a commonly identified complication after resection and anastomosis of the colon. A novel technique was used in 2 cases of colonic prolapse, in which sterile, semirigid rubber tubing was placed in the distal colon and removed per-cloaca at the end of the procedure; this facilitated a secure, fluid-tight anastomosis while maintaining sufficient intestinal lumen. Oviductal prolapse (31% of cases) was associated with the most guarded prognosis (40% treatment success). Cloacoliths were treated successfully in 2 birds (13% of cases) by minimally invasive per-cloacal manual removal.

Lipid emulsions in the treatment and prevention of parenteral nutrition-associated liver disease in infants and children

Long-term parenteral nutrition (PN) carries the risk of progressive liver disease in infants with intestinal failure. Although PN-associated liver disease (PNALD) is multifactorial in etiology, components of soybean oil lipid emulsions have been implicated in the disease's pathogenesis. Historically, infants with PNALD who were unable to wean from PN to full enteral feeding developed cirrhosis and end-stage liver disease, which require liver transplantation to survive. Over the past 2 decades, novel strategies for the management of parenteral lipids have improved morbidity and mortality from PNALD in infants with intestinal failure. Current strategies for the treatment of PNALD include restricting the dose of parenteral soybean oil lipid emulsion and/or replacing the soybean oil with a parenteral fish-oil lipid emulsion or emulsions of mixed-lipid sources. The purpose of this report is to review published data that evaluate these strategies in parenteral lipid management for the treatment and prevention of PNALD.

[Advances in the management of children with intestinal failure]

Intestinal failure is defined as the reduction of a functional gut mass below the minimal necessary for adequate digestion and absorption of nutrients and fluids. Intestinal failure is the final result of a number of different causes, being short bowel syndrome the most recognized. Its prevalence is low, but the impact in quality of life among patients and their families is critical. Furthermore, is associated with high economic costs, both for the patient and the health provider. Its main feature is the need for long-term parenteral nutritional support with high morbidity and mortality associated complications, such as line-derived bloodstream infections and liver disease. The management of these patients should be performed by a multidisciplinary team, and be aimed at promoting adaptation and recovery of bowel function to achieve intestinal autonomy.

Validity and reliability of a Lithuanian version of low anterior resection syndrome score

BACKGROUND

Up to 90 % of patients undergoing low anterior resection complain of increased daily bowel movements, urgency, and a variable degree of incontinence. A symptom-based scoring system for bowel dysfunction after low anterior resection for rectal cancer has recently been developed and validated. The aim of our study was to adapt the low anterior resection syndrome (LARS) scale questionnaire to the Lithuanian language, and assess its psychometric properties.

METHODS

The LARS questionnaire was translated into Lithuanian by the Scientific Advisory Committee of the Medical Outcomes Trust using a standard procedure of double-back translation. The Lithuanian version of the LARS (LARS-LT) questionnaire was completed by 111 patients who underwent low anterior resection with total mesorectal excision in the period from January 1, 2008, to December 31, 2012, at the National Cancer Institute. An anchor question from the Wexner score assessing the impact of bowel function on lifestyle was included. A subgroup of 20 patients completed the LARS-LT questionnaire twice. Validity was tested using a factor analysis, and internal reliability was estimated using the Cronbach's alpha and intraclass correlation coefficients.

RESULTS

Twenty-seven patients (25 %) had no LARS, 26 (24 %) had minor LARS, and 55 (56 %) had major LARS. The response rate was 60.7 %. The LARS-LT showed significantly high reliability and internal consistency [Cronbach's α = 0.88, interclass correlation coefficient-0.86 (0.71-0.98)]. The LARS score showed significant correlations with the lifestyle question (p < 0.05). It could not detect differences between female and male patient groups (p = 0.33), patients' age (p = 0.45), patients who had/had not undergone radiation therapy (p = 0.07), and those in whom the distal edge of the tumor was close to or far from the anal verge (p = 0.17).

CONCLUSIONS

The Lithuanian version of the LARS-LT shows acceptable psychometric properties and can be considered a valuable and specific instrument to assess bowel function in rectal cancer patients, both for research purposes and in clinical practice.

[INVOLVEMENT OF THE GASTROINTESTINAL TRACT IN RHEUMATIC DISEASES]

AIM

The aim of the present study was to show different aspects of the interrelation between pathology of the gastrointestinal tract and rheumatic diseases based on literature rewiev, single-centers data and case reports.

MATERIALS AND METHODS

First literature review was performed (databases PubMed, Medline). Then was analyzed information according presence of gastrointestinal disease in 126 patients with axial spondyloarthritis (SpA) and collected case reports as illustration the problem.

RESULTS

Involvement of the gastrointestinal tract in rheumatic diseases in general is characterized by clinical, etiologycal and pathogenetic heterogeneity. It was found a few typical combinations: the defeat of the digestive tract as one of the clinical manifestations of rheumatic disease (hemorrhagic vasculitis, etc.); the defeat of the digestive tract and rheumatic disease as equal related conditions (Crohn’s disease and ankylosing spondylitis); the defeat of the digestive tract as a consequence of long-existing inflammation (amyloidosis, esophagus Barrett); gastrointestinal tract involvement as complication of treatment of the rheumatic disease (bleeding when using nonsteroidal anti-inflammatory drugs); rheumatic disease as a manifestation of paraneoplastic syndrome of the digestive tract. The presence of diseases of the gastrointestinal tract is established in more than half (58%) patients with axial SpA. In the group of patients considered the most frequently met gastritis (15%), chronic pancreatitis (15.9%) and chronic cholecystitis (19%).

CONCLUSIONS

Gastrointestinal tract occurs no less than half of the patients with rheumatic diseases and may be either primary or secondary to systemic disease. The possibility of coexistence of diseases of the gastrointestinal tract and rheumatic disease must be taken into account in the course of patient care. In some cases, treatment should be carried out together - a gastroenterologist and a rheumatologist.

[Mesenteric venous thrombosis during pregnancy; a rare cause of acute ischaemia of the small intestine]

BACKGROUND

Acute ischaemia of the small intestine is caused by mesenteric venous thrombosis in 5-15% of patients. The non-specific symptoms frequently lead to a diagnostic delay.

CASE DESCRIPTION

A 30-year-old pregnant woman presented at the accident and emergency department with progressive abdominal pain, nausea and vomiting. During admission the patient developed signs of peritonitis. Diagnostic laparoscopy revealed a picture of mesenteric venous thrombosis, and we resected 170 cm ischemic small intestine. No underlying cause was identified, apart from the pregnancy. The patient was treated with low-molecular-weight heparin and later gave birth to a healthy child.

CONCLUSION

If a patient presents with (unexplained) progressive abdominal symptoms and disproportional abdominal pain without peritonitis, the possibility of intestinal ischaemia should be considered during differential diagnosis.

Multiple Mesenteric Panniculitis as a Complication of Sjögren's Syndrome Leading to Ileus

Mesenteric panniculitis (MP) is a benign fibroinflammatory process characterized by the presence of fat necrosis, chronic inflammation and fibrosis in the mesentery. Although various causal factors, such as malignancy, chronic inflammatory conditions and autoimmune processes, have been identified, the precise etiology remains unknown. We herein report a rare case of MP accompanying Sjögren's syndrome in which a mass lesion and intestinal stenosis were observed simultaneously. This condition led to ileus, which was effectively treated using prednisolone.

To Study the Aetiological Factors and Outcomes of Urgent Re-Laparotomy in Himalayan Hospital

BACKGROUND

Treatment of a number of complications that occur after abdominal surgeries may require that Urgent Relaparotomy (UR), the life-saving and obligatory operations, are performed. The objectives of this study were to evaluate the reasons for performing URs, their outcomes and factors that affect mortality.

METHODS

Observational, Prospective Study. The study included all the patients who underwent urgent re-laparotomy following laparotomy (emergency, elective) in Himalayan Hospital from 01.01.2013 to 01.06.2014 and excluded those who underwent laparotomy outside.

RESULTS

UR was performed for 40 out of 1050 patients (4.2%), of which males were 25 and females 15. The average time interval between the index laparotomy and urgent re-exploration was 6.4 days. The most common reason for mortality was multi organ failure with septic shock. The most common criteria for re-exploration were anastomotic leak (n=13), followed by pyoperitoneum (n=11) and persistent peritonitis (n=6). Comparing the index surgery, lower gastro-intestinal procedures were most usually involved (n=21, 47.7%), followed by hepato-pancreato-biliary surgeries (n=8, 18.2%). There were 6 cases of upper gastro-intestinal surgeries that reexplored (13.6%).

CONCLUSION

UR that is performed following complicated abdominal surgeries has high mortality rates. In particular, they have higher mortality rates following GIS surgeries or when infectious complications occur.

[Not Available]

Intussusception is rare in adults and has different characteristics from intussusceptions of children. Its clinical manifestations are varied and often nonspecific, requiring a high index of suspicion for diagnosis. Within the study methods, computed tomography has become fundamental in the study of abdominal pain. This has a high sensitivity and specificity for the diagnosis of intussusception. Most of the time the treatment is surgical, and succeeded in identifying the underlying lesions. We review the basics concepts, pathophysiology, imaging findings and frequent etiologies that can cause intussusception in adults.

Citrulline as a Biomarker in the Murine Total-Body Irradiation Model: Correlation of Circulating and Tissue Citrulline to Small Intestine Epithelial Histopathology

The use of plasma citrulline as a biomarker for gastrointestinal acute radiation syndrome via exposure to total-body irradiation in a murine model was investigated. The radiation exposure covered lethal, mid-lethal, and sub-lethal gastrointestinal acute radiation syndrome. Plasma citrulline profiles were generated over the first 6 d following total-body irradiation exposure of 6-15 Gy. In addition, plasma citrulline was comprehensively evaluated in the context of matching small intestine citrulline and histopathology. Higher plasma citrulline was significantly associated with lower irradiation doses over the first 6 d following the irradiation insult. Furthermore, higher plasma citrulline was significantly associated with higher crypt survival. The correlation of the plasma citrulline to crypt survival was more robust for higher irradiation doses and for later time points. The data suggested plasma citrulline was most informative for reflecting gastrointestinal injury resulting from exposure to 9-15 Gy total-body irradiation covering time-points 2-5 d post the irradiation insult.

The Delayed Effects of Acute Radiation Syndrome: Evidence of Long-Term Functional Changes in the Clonogenic Cells of the Small Intestine

Long term or residual damage post-irradiation has been described for many tissues. In hematopoietic stem cells (HSC), this is only revealed when the HSC are stressed and required to regenerate and repopulate a myeloablated host. Such an assay cannot be used to assess the recovery potential of previously irradiated intestinal stem cells (ISC) due to their incompatibility with transplantation. The best approximation to the HSC assay is the crypt microcolony assay, also based on clonogen survival. In the current study, the regenerative capacity of intestinal clonogenic cells in mice that had survived 13 Gy irradiation (with 5% bone marrow shielding to allow survival through the hematopoietic syndrome) and were then aged for 200 d was compared to previously unirradiated age-matched controls. Interestingly, at 200 d following 13 Gy, there remained a statistically significant reduction in crypts present in the various small intestinal regions (illustrating that the gastrointestinal epithelium had not fully recovered despite the 200-d interval). However, upon re-irradiation on day 196, those mice previously irradiated had improved crypt survival and regeneration compared to the age-matched controls. This was evident in all regions of the small intestine following 11-13 Gy re-exposure. Thus, there were either more clonogens per crypt within those previously irradiated and/or those that were present were more radioresistant (possibly because a subpopulation was more quiescent). This is contrary to the popular belief that previously irradiated animals may have an impaired/delayed regenerative response and be more radiosensitive.

Spatial-temporal clustering of companion animal enteric syndrome: detection and investigation through the use of electronic medical records from participating private practices

There is interest in the potential of companion animal surveillance to provide data to improve pet health and to provide early warning of environmental hazards to people. We implemented a companion animal surveillance system in Calgary, Alberta and the surrounding communities. Informatics technologies automatically extracted electronic medical records from participating veterinary practices and identified cases of enteric syndrome in the warehoused records. The data were analysed using time-series analyses and a retrospective space-time permutation scan statistic. We identified a seasonal pattern of reports of occurrences of enteric syndromes in companion animals and four statistically significant clusters of enteric syndrome cases. The cases within each cluster were examined and information about the animals involved (species, age, sex), their vaccination history, possible exposure or risk behaviour history, information about disease severity, and the aetiological diagnosis was collected. We then assessed whether the cases within the cluster were unusual and if they represented an animal or public health threat. There was often insufficient information recorded in the medical record to characterize the clusters by aetiology or exposures. Space-time analysis of companion animal enteric syndrome cases found evidence of clustering. Collection of more epidemiologically relevant data would enhance the utility of practice-based companion animal surveillance.

Environmental enteric dysfunction: an overview

BACKGROUND

Environmental enteric dysfunction (EED) refers to an incompletely defined syndrome of inflammation, reduced absorptive capacity, and reduced barrier function in the small intestine. It is widespread among children and adults in low- and middle-income countries. Understanding of EED and its possible consequences for health is currently limited.

OBJECTIVE

A narrative review of the current understanding of EED: epidemiology, pathogenesis, therapies, and relevance to child health.

METHODS

Searches for key papers and ongoing trials were conducted using PUBMED 1966-June 2014; ClinicalTrials.gov; the WHO Clinical Trials Registry; the Cochrane Library; hand searches of the references of retrieved literature; discussions with experts; and personal experience from the field.

RESULTS

EED is established during infancy and is associated with poor sanitation, certain gut infections, and micronutrient deficiencies. Helicobacter pylori infection, small intestinal bacterial overgrowth (SIBO), abnormal gut microbiota, undernutrition, and toxins may all play a role. EED is usually asymptomatic, but it is important due to its association with stunting. Diagnosis is frequently by the dual sugar absorption test, although other biomarkers are emerging. EED may partly explain the reduced efficacy of oral vaccines in low- and middle-income countries and the increased risk of serious infection seen in children with undernutrition.

CONCLUSIONS

Despite its potentially significant impacts, it is currently unclear exactly what causes EED and how it can be treated or prevented. Ongoing trials involve nutritional supplements, water and sanitation interventions, and immunomodulators. Further research is needed to better understand this condition, which is of likely crucial importance for child health and development in low- and middle-income settings.

Application of 1H NMR spectroscopy-based metabonomics to feces of cervical cancer patients with radiation-induced acute intestinal symptoms

OBJECTIVE

Radiation-induced acute intestinal symptoms (RIAISs) are a common complication of radiotherapy for cervical cancer. The aim of this study was to use (1)H nuclear magnetic resonance ((1)H NMR) combined with chemometric analysis to develop a metabolic profile of patients with RIAISs.

METHODS

Fecal samples were collected from 66 patients with cervical cancer before and after pelvic radiotherapy. After radiotherapy, RIAISs occurred in eleven patients. We selected another 11 patients from participants without RIAISs whose age, stage, histological type and treatment methods are matched with RIAIS patients as the control group. (1)H NMR spectroscopy combined with multivariate pattern recognition analysis was used to generate metabolic profile data, as well as to establish a RIAIS-specific metabolic phenotype.

RESULTS

Orthogonal partial least-squares discriminant analysis was used to distinguish samples between the pre- and post-radiotherapy RIAIS patients and between RIAIS patients and controls. Fecal samples from RIAIS patients after pelvic radiotherapy were characterized by increased concentrations of α-ketobutyrate, valine, uracil, tyrosine, trimethylamine N-oxide, phenylalanine, lysine, isoleucine, glutamine, creatinine, creatine, bile acids, aminohippurate, and alanine, accompanied by reduced concentrations of α-glucose, n-butyrate, methylamine, and ethanol relative to samples from RIAIS patients before pelvic radiotherapy, while in RIAIS patients relative to controls, trimethylamine, n-butyrate, fumarate and acetate were down-regulated and valine, TMAO, taurine, phenylalanine, lactate, isoleucine and creatinine were up-regulated.

CONCLUSIONS

We obtained the metabolic profile of RIAIS patients from fecal samples using NMR-based metabonomics. This profile has the potential to be developed into a novel clinical tool for RIAIS diagnosis or therapeutic monitoring, and could contribute to an improved understanding of the disease mechanism. However, because of the limitations of methods, technique, bacterial contamination of feces and small sample size, further research and verification are needed.

Commentary on: "Long-term functional outcomes after treatment for localized prostate cancer." Resnick MJ, Koyama T, Fan KH, Albertsen PC, Goodman M, Hamilton AS, Hoffman RM, Potosky AL, Stanford JL, Stroup AM, Van Horn RL, Penson DF. Department of Urologic Surgery and the Center for Surgical Quality and Outcomes Research, Vanderbilt University, Nashville, TN.: N Engl J Med 2013;368(5):436-45. doi: 10.1056/NEJMoa1209978

BACKGROUND

The purpose of this analysis was to compare long-term urinary, bowel, and sexual function after radical prostatectomy or external-beam radiation therapy.

METHODS

The Prostate Cancer Outcomes Study (PCOS) enrolled 3533 men in whom prostate cancer had been diagnosed in 1994 or 1995. The current cohort comprised 1655 men in whom localized prostate cancer had been diagnosed between the ages of 55 and 74 years and who had undergone either surgery (1164 men) or radiotherapy (491 men). Functional status was assessed at baseline and at 2, 5, and 15 years after diagnosis. We used multivariable propensity scoring to compare functional outcomes according to treatment.

RESULTS

Patients undergoing prostatectomy were more likely to have urinary incontinence than were those undergoing radiotherapy at 2 years (odds ratio, 6.22; 95% confidence interval [CI], 1.92 to 20.29) and 5 years (odds ratio, 5.10; 95% CI, 2.29 to 11.36). However, no significant between-group difference in the odds of urinary incontinence was noted at 15 years. Similarly, although patients undergoing prostatectomy were more likely to have erectile dysfunction at 2 years (odds ratio, 3.46; 95% CI, 1.93 to 6.17) and 5 years (odds ratio, 1.96; 95% CI, 1.05 to 3.63), no significant between-group difference was noted at 15 years. Patients undergoing prostatectomy were less likely to have bowel urgency at 2 years (odds ratio, 0.39; 95% CI, 0.22 to 0.68) and 5 years (odds ratio, 0.47; 95% CI, 0.26 to 0.84), again with no significant between-group difference in the odds of bowel urgency at 15 years.

CONCLUSIONS

At 15 years, no significant relative differences in disease-specific functional outcomes were observed among men undergoing prostatectomy or radiotherapy. Nonetheless, men treated for localized prostate cancer commonly had declines in all functional domains during 15 years of follow-up. (Funded by the National Cancer Institute.).

Different roles of capsule endoscopy and double-balloon enteroscopy in obscure small intestinal diseases

AIM: To compare the roles of capsule endoscopy (CE) and double-balloon enteroscopy (DBE) in the diagnosis of obscure small bowel diseases.

METHODS: From June 2009 to December 2014, 88 patients were included in this study; the patients had undergone gastroscopy, colonoscopy, radiological small intestinal barium meal, abdominal computed tomography or magnetic resonance imaging scan and mesenteric angiography, but their diagnoses were still unclear. The patients with gastrointestinal obstructions, fistulas, strictures, or cardiac pacemakers, as well as pregnant women, and individuals who could not accept the capsule-retention or capsule-removal surgery were excluded. Patients with heart, lung and other vital organ failure diseases were also excluded. Everyone involved in this study had undergone CE and DBE. The results were divided into: (1) the definite diagnosis (the diagnosis was confirmed at least by one of the biopsy, surgery, pathology or the drug treatment effects with follow-up for at least 3 mo); (2) the possible diagnosis (a possible diagnosis was suggested by CE or DBE, but not confirmed by the biopsy, surgery or follow-up drug treatment effects); and (3) the unclear diagnosis (no exact causes were provided by CE and DBE for the disease). The detection rate and the diagnostic yield of the two methods were compared. The difference in the etiologies between CE and DBE was estimated, and the different possible etiologies caused by the age groups were also investigated.

RESULTS: CE exhibited a better trend than DBE for diagnosing scattered small ulcers (P = 0.242, Fisher’s test), and small vascular malformations (χ² = 1.810, P = 0.179, Pearson χ² test), but with no significant differences, possible due to few cases. However, DBE was better than CE for larger tumors (P = 0.018, Fisher’s test) and for diverticular lesions with bleeding ulcers (P = 0.005, Fisher’s test). All three hemangioma cases diagnosed by DBE in this study (including sponge hemangioma, venous hemangioma, and hemangioma with hamartoma lesions) were all confirmed by biopsy. Two parasite cases were found by CE, but were negative by DBE. This study revealed no obvious differences in the detection rates (DR) of CE (60.0%, 53/88) and DBE (59.1%, 52/88). However, the etiological diagnostic yield (DY) difference was apparent. The CE diagnostic yield was 42.0% (37/88), and the DBE diagnostic yield was 51.1% (45/88). Furthermore, there were differences among the age groups (χ² = 22.146, P = 0.008, Kruskal Wallis Test). Small intestinal cancer (5/6 cases), vascular malformations (22/29 cases), and active bleeding (3/4 cases) appeared more commonly in the patients over 50 years old, but diverticula with bleeding ulcers were usually found in the 15-25-year group (4/7cases). The over-25-year group accounted for the stromal tumors (10/12 cases).

CONCLUSION: CE and DBE each have their own advantages and disadvantages. The appropriate choice depends on the patient’s age, tolerance, and clinical manifestations. Sometimes CE followed by DBE is necessary.

Intestinal Infarction Caused by Thrombophlebitis of the Portomesenteric Veins as a Complication of Acute Gangrenous Appendicitis After Appendectomy: A Case Report

The clinical symptoms of pylephlebitis caused by acute appendicitis are varied and atypical, which leads to delayed diagnosis and poor outcomes. Here, we report a case of intestinal necrosis caused by thrombophlebitis of the portomesenteric veins as a complication of acute appendicitis after appendectomy. The patient had acute abdominal pain with tenderness and melena on the 3rd day after appendectomy for the treatment of gangrenous appendicitis. He was diagnosed with intestinal infarction caused by thrombophlebitis of the portomesenteric veins based on enhanced CT and diagnostic abdominal paracentesis. The patient was treated by bowel excision anastomosis and thrombectomy. After postoperative antibiotic and anticoagulation treatments, the patient recovered well and was discharged 22 days after the 2nd operation. A follow-up CT scan showed no recurrence of portomesenteric veins thrombosis 3 months later. Thrombophlebitis of the portomesenteric veins is a rare but fatal complication of acute appendicitis. For all the cases with acute abdominal pain, the possibility of thrombophlebitis should be considered as a differential diagnosis. Once pylephlebitis is suspected, enhanced CT scan is helpful for early diagnosis, and sufficient control of inflammation as well as anticoagulant therapy should be performed.

Geophagy is associated with environmental enteropathy and stunting in children in rural Bangladesh

There is a growing body of literature indicating an association between stunting and environmental enteropathy (EE), a disorder thought to be caused by repeated exposures to enteric pathogens. To investigate the relationship between exposure to enteric pathogens through geophagy, consumption of soil, EE, and stunting, we conducted a prospective cohort study of 216 children under 5 years of age in rural Bangladesh. Geophagy was assessed at baseline using 5 hour structured observation and caregiver reports. Stool was analyzed for fecal markers of intestinal inflammation: alpha-1-antitrypsin, myeloperoxidase, neopterin (all three combined to form an EE disease activity score), and calprotectin. Eighteen percent of children had observed geophagy events by structured observation and 28% had caregiver reported events in the past week. Nearly all households had Escherichia coli (97%) in soil, and 14% had diarrheagenic E. coli. Children with caregiver-reported geophagy had significantly higher EE scores (0.72 point difference, 95% confidence interval [CI]: 0.01, 1.42) and calprotectin concentrations (237.38 μg/g, 95% CI: 12.77, 462.00). Furthermore, at the 9-month follow-up the odds of being stunted (height-for-age z-score < -2) was double for children with caregiver-reported geophagy (odds ratio [OR]: 2.27, 95% CI: 1.14, 4.51). These findings suggest that geophagy in young children may be an important unrecognized risk factor for EE and stunting.

Acute and Late Bowel Toxicity in Radiotherapy Patients with Inflammatory Bowel Disease: A Systematic Review

AIMS

Inflammatory bowel disease has traditionally been considered a relative contraindication for radiotherapy due to a perceived increased risk of disease exacerbation and bowel toxicity. The aim of this review was to evaluate the current literature regarding rates of radiotherapy-induced acute and late bowel toxicity in patients with inflammatory bowel disease and to compare these data with those of patients without the disease.

MATERIALS AND METHODS

An Ovid Medline search was conducted to identify original articles pertaining to the review question. Using the PRISMA convention a total of 442 articles screened, resulting 8 articles which were suitable for inclusion in the review.

RESULTS

In general, the grading of toxicity was scored using either the Radiation Therapy Oncology Group or Common Terminology Criteria for Adverse Events scoring systems. It was found that acute bowel toxicity of ≥ grade 3 occurred in 20% of patients receiving external beam radiotherapy (EBRT) and in 7% of patients receiving brachytherapy. Late bowel toxicity ≥ grade 3 occurred in 15% of EBRT patients and in 5% of patients receiving brachytherapy. Brachytherapy was shown to have similar rates of toxicity and EBRT produced a moderate increase in both acute and late toxicity when compared with individuals without inflammatory bowel disease.

CONCLUSION

In view of these results, we suggest that brachytherapy should be considered as a suitable treatment option for treating pelvic malignancy in patients with inflammatory bowel disease, whereas EBRT should be used with caution.
