RESUMO
BACKGROUND AND AIMS: Split-dose bowel preparation is associated with improved mucosal visualization and patient tolerance, becoming a standard of care. However, quality measures data associated with this preparation are limited. At our academic tertiary-care facility, we aim to study the effect of changing from single- to split-dose preparation on colonoscopy quality measures. METHODS: A retrospective cohort study with quality indicators was conducted using electronic medical record data. Cases were identified via ICD9 code V76.51, "Special screening for malignant neoplasms of colon." Single-dose preparation data was collected from 9/1/13 to 8/31/14. Split-dose preparation was implemented 11/2014, and data were collected from 1/1/15 to 8/31/15. RESULTS: A total of 1602 colonoscopies in the single-dose group and 1061 colonoscopies in the split-dose group were analyzed. The Boston Bowel Preparation Scale was significantly improved in the split-dose group 8.64 ± SD 1.25 versus 8.25 ± SD 1.61, p < 0.001. There was no significant difference in adenoma detection rate 40.7% (95% CI 37.8-43.7%) versus 40.5% (95% CI 38.1-42.9%), p = 0.92; however, the rate for recommending an early repeat examination due to an inadequate bowel preparation was significantly decreased to 3.9% (95% CI 2.7-5.0%) versus 8.9% (95% CI 1.52-2.97%), p < 0.001. CONCLUSION: While split-dose preparation significantly improves overall bowel cleanliness, there is no significant adenoma detection rate improvement with high baseline rate, suggesting a threshold which may not improve with enhanced preparations. Split-dose preparation significantly reduces the frequency with which inadequate preparation prompts an early repeat examination, which has important clinical implications on performance, costs, and patient experience, providing further evidence supporting split-dose preparation use.

OBJECTIVE: Acute dysphagia/odynophagia developed in a 79-year-old female patient secondary to what we believe was a caustic injury to a large Zenker's diverticulum (ZD) in the setting of long-term alendronate use. She reported severe dysphagia and odynophagia of 1-week duration. She had experienced a similar episode 10 months earlier that had resolved after stopping alendronate temporarily. Although she was able to handle secretions, she was unable to swallow solids or liquids. She was noted to be dehydrated. On endoscopy, a large and markedly inflamed ZD was identified. There was no visual esophageal mucosal injury within the esophagus. Alendronate therapy was discontinued, and parenteral nutrition and proton pump inhibitors were initiated. Her symptoms resolved within 1 week, and she was able to resume oral intake. DESIGN: Case report. SETTING: University Hospital. LIMITATIONS: Case report. DISCUSSION: Bisphosphonate therapy is commonly used to treat osteoporosis and is therefore an increasingly prevalent component of the medication list of elderly patients. These medications may cause significant caustic injury and are therefore administered with strong caution in the setting of dysphagia or known structural abnormalities of the esophagus. The fear is that tablets may become entrapped within a diverticulum and lead to intense acute inflammatory changes. CONCLUSIONS: Health care providers should be aware of potential complications with ulcerogenic medications in patients with ZD. These medications should be administered with caution in the setting of dysphagia or known structural abnormalities of the esophagus. When patients with history of dysphagia are evaluated for their suitability to receive oral bisphosphonate therapy, care should be taken to investigate the etiology of dysphagia. Evaluation should focus not only on the tubular esophagus, but also on excluding a Zenker's pharyngeal diverticulum with appropriate contrast imaging.
