INTRODUCTION: Inpatient status has been shown to be a predictor of poor bowel preparation for colonoscopy since these patients are usually older, less mobile, have more medical comorbidities, and often require emergent evaluation. Our aim was to compare the efficacy of bowel preparation volume size in hospitalized patients undergoing inpatient colonoscopy. METHODS: This prospective, single blinded (endoscopist), randomized controlled trial was IRB approved and conducted as a pilot study at a Tertiary Referral Medical Center between September 2013 and March 2019. Hospitalized patients aged 18 years or older undergoing inpatient colonoscopy were assigned randomly to receive a high-volume solution (GoLYTELY®, medium-volume solution (MoviPrep®) or a low-volume Prepopik® solution. Adverse effects including unpleasant taste, nausea, and vomiting were scored through a questionnaire using a five-point scale ranging from 0 (no symptoms) to 4 (severe symptoms). Boston Bowel Prep Score (BBPS) was used to evaluate colon cleanliness. Descriptive statistics are presented as mean values ± standard deviation (SD), and P -values were calculated using Chi-Square and Kruskal-Wallis tests. RESULTS: Twenty-five colonoscopies were performed in 25 subjects. Mean age was 66.6 years (16.34) and 68% were male (Table 1). Indications for colonoscopy varied and are shown in Table 1. Total BBPS scores were higher in patients who received Prepopik®, 7.4 (1.62), than GoLYTELY® 6.6 (2.19) or MoviPrep® 6.9 (1.55), P = 0.66 (Figure 1). There was no difference in BBPS in right, transverse, or left colon scores. Regarding tolerance to preparation, 100% of the Prepopik® group reported completing the bowel preparation compared to 77.8% of the GoLYTELY® group and 66.4% of the MoviPrep® group ( P = 0.24). The Prepopik® group reported fewer side effects than GoLYTELY®/MoviPrep® groups (Table 2). CONCLUSION: In this pilot study, a low-volume colon preparation demonstrated at least equivalent quality of bowel preparation measured by BBPS in comparison with traditional higher volume regimens, with less adverse effects, and better compliance for cleansing completion. This study suggests small volume purgative may lead to better patient compliance and therefore, better bowel preparation in the inpatient setting. The lack of statistical significance is likely due to a type II error. Further more robust studies are required to confirm these findings.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a rare but potentially life-threatening cutaneous hypersensitivity reaction characterized by extensive mucocutaneous eruption, fever, hematologic abnormalities, and extensive organ involvement. Here, we present a case of a young woman with DRESS syndrome following exposure to vancomycin with renal, cutaneous, and gastrointestinal involvement. To the best of our knowledge, this is the first case description in the literature of DRESS of the gastrointestinal tract with autoimmune enteropathy.

A 66-year-old male patient presented with nausea, abdominal pain, occasional rectal bleeding, progressive dysgeusia, onicodystrophy, and alopecia. Endoscopic exam and biopsies revealed severe atrophy and diffuse marked edema of mucosa of stomach and duodenum. No evidence of polyps was found in any portion of the gastrointestinal tract. The diagnosis of Cronkhite–Canada syndrome (CCS) was rendered. The patient symptoms resolved completely after initiation of steroid treatment. This additional case of CCS illustrates how the diagnosis of CCS does not require the presence of polyps but is defined by the appreciation of the diffuse marked edema and atrophy of the gastrointestinal mucosa.
