Role of video capsule endoscopy in patients with constitutional mismatch repair deficiency (CMMRD) syndrome: report from the International CMMRD Consortium.

BACKGROUND AND STUDY AIMS: Constitutional mismatch repair deficiency (CMMRD) syndrome, also known as biallelic mismatch repair deficiency (BMMRD) syndrome is a rare autosomal-recessive genetic disorder that has a high mortality due to malignancy in childhood and early adulthood. The small bowel phenotype in CMMRD is not well described and surveillance protocols for small bowel cancer have not been well established. This study was conducted to evaluate the usefulness and clinical impact of video capsule endoscopy (VCE) for small bowel surveillance. PATIENTS AND METHODS: We retrospectively reviewed the prospectively maintained International CMMRD Consortium database. Treating physicians were contacted and VCE report data were extracted using a standardized template. RESULTS: Among 58 patients included in the database, 38 VCE reports were collected from 17 patients. Polypoid lesions were first detected on VCE at a median age of 14 years (range: 4 - 17). Of these, 39 % in 7 patients (15/38) showed large polypoid lesions (> 10 mm) or multiple polyps that prompted further investigations. Consequently, three patients were diagnosed with small bowel neoplasia including one patient with adenocarcinoma. Small bowel neoplasia and/or cancer were confirmed histologically in 35 % of the patients (6/17) who had capsule surveillance and the lesions in half of these patients were initially visualized on VCE. Multiple polyps were identified on eight VCEs that were completed on three patients. Ten VCEs (28 %) were incomplete due to slow bowel transit; none required capsule removal. CONCLUSIONS: Small bowel surveillance in patients with CMMRD should be initiated early in life. VCE has the potential to detect polyps; however, small bowel neoplasias are often proximal and can be missed, emphasizing the importance of concurrent surveillance with other modalities.

Fluticasone propionate for treatment of esophageal lichen planus. A case series.

Esophageal lichen planus is a rare condition, and although the majority of cases occur in conjunction with lichen planus at other sites, the endoscopic features are often misinterpreted resulting in a delay in diagnosis. We report a series of five patients presenting to our unit between 2005 and 2009. All five patients were female and presented with dysphagia. Endoscopy demonstrated proximal esophageal stricturing in four patients. Characteristic histological findings were found in four patients. Lichen planus was diagnosed at other sites, and preceded gastrointestinal symptoms, in all patients; five had oral involvement, two had genital involvement, and one had dermal involvement. All patients received proton pump inhibitor therapy without demonstrable benefit. Administration of oral fluticasone proprionate resulted in symptomatic improvement in three patients.

A randomized, double-blind study of the use of droperidol for conscious sedation during therapeutic endoscopy in difficult to sedate patients.

BACKGROUND: Droperidol has been used in combination with narcotics and benzodiazepines to achieve conscious sedation. We performed a randomized, double-blind, study of droperidol in patients at risk for difficult sedation scheduled for therapeutic endoscopy. METHODS: Patients with regular ethanol, narcotic, or benzodiazepine usage, suspected sphincter of Oddi dysfunction, or a history of difficult sedation were eligible for the study. Patients were randomized to receive either droperidol or placebo along with midazolam and meperidine as preprocedure sedation. Time to achieve sedation, interruptions due to undersedation, medication dosages, recovery time, and subjective assessments of sedation were recorded. RESULTS: One hundred one patients were randomized. The droperidol group had significantly fewer procedure interruptions and observer ratings of difficulty with sedation and required significantly less midazolam (23%) and meperidine (16%) than the placebo group. There were no significant differences in time to achieve sedation, incomplete procedures, procedure length, recovery room time, or complications. There were significantly higher observer ratings of the quality of sedation for patients who received droperidol. CONCLUSIONS: Droperidol is a useful adjunct to conscious sedation in patients who are difficult to sedate. Its use results in significantly fewer interruptions due to poor sedation and improved sedation ratings compared with sedation using midazolam and meperidine alone.

Same-day discharge after endoscopic biliary sphincterotomy: observations from a prospective multicenter complication study. The Multicenter Endoscopic Sphincterotomy (MESH) Study Group.

BACKGROUND: Same-day discharge after endoscopic biliary sphincterotomy (ES) is a common clinical practice, but there have been few data to guide appropriate selection of patients. Using a prospective, multicenter database of complications, we examined outcomes after same-day discharge as it was practiced by a variety of endoscopists and evaluated the ability of a multivariate risk factor analysis to predict which patients would require readmission for complications. METHODS: A 150-variable database was prospectively collected at time of ES, before discharge and again at 30 days in consecutive patients undergoing ES at 17 centers. Complications were defined by consensus criteria and included all specific adverse events directly or indirectly related to ES requiring more than 1 night of hospitalization. RESULTS: Six hundred fourteen (26%) of 2347 patients undergoing ES were discharged on the same day as the procedure, ranging from none at 6 centers to about 50% at 2 centers. After initial observation and release, readmission to the hospital for complications occurred in 35 (5.7%) of 614 same-day discharge patients (20 pancreatitis and 15 other complications, 3 severe). Of the same-day discharge patients, readmission was required for 14 (12.2%) of 115 who had at least one independently significant multivariate risk factor for overall complications (suspected sphincter of Oddi dysfunction, cirrhosis, difficult bile duct cannulation, precut sphincterotomy, or combined percutaneous-endoscopic procedure) versus 21 (4.2%) of 499 without a risk factor (odds ratio 3.1: 95% confidence interval [1.6, 6.3], p < 0.001). Of complications presenting within 24 hours after ES, only 44% presented within the first 2 hours, but 79% presented within 6 hours. CONCLUSIONS: Same-day discharge is widely utilized and relatively safe but results in a significant number of readmissions for complications. For patients at higher risk of complications, as indicated by the presence of at least one of five independent predictors, observation for 6 hours or overnight may reduce the need for readmission.

A prospective study of the safety of endoscopic therapy for choledocholithiasis in an outpatient population.

OBJECTIVE: Many centers routinely admit patients for observation after endoscopic therapy of choledocholithiasis although this is contrary to the current mandate for cost containment. The purpose of this study was to determine the safety, success, and complication rates of outpatient therapeutic ERCP in the management of choledocholithiasis. METHODS: Over a 4-month period, 97 consecutive outpatients undergoing endoscopic treatment for choledocholithiasis were enrolled in a prospective manner. Each subject was observed 1-3 h postprocedure before discharge with follow-up at 10 days. RESULTS: Successful endoscopic management of choledocholithiasis was achieved in 100% of patients. Complication rates were as follows: pancreatitis (2.1%), postsphincterotomy bleeding (3.2%), perforation (0%), and sepsis (0%). One patient required admission during the observation period, and two others with pancreatitis were readmitted within 24 h of discharge. There was no apparent adverse clinical outcome related to this policy. CONCLUSION: Endoscopic therapy of choledocholithiasis may be performed safely on an outpatient basis, realizing significant cost savings.

Esophageal candidiasis associated with beclomethasone dipropionate aerosol therapy.

A 23-year-old woman with asthma developed severe heartburn while using beclomethasone dipropionate. Esophageal candidiasis was diagnosed on endoscopy and confirmed by biopsy. Subsequent studies revealed mild hypogammaglobulinemia and mild impairment of neutrophil candidacidal activity, the significance of which is unknown. Esophageal candidiasis associated with the use of inhaled beclomethasone has not been previously reported.
