Bleeding risk with clopidogrel and percutaneous endoscopic gastrostomy

AIM

To compare bleeding within 48 h in patients undergoing percutaneous endoscopic gastrostomy (PEG) with or without clopidogrel.

METHODS

After institutional review board approval, a retrospective study involving a single center was conducted on adult patients having PEG (1/08-1/14). Patients were divided into two groups: Clopidogrel group consisting of those patients taking clopidogrel within 5 d of PEG and the non-clopidogrel group including those patients not taking clopidogrel within 5 d of the PEG.

RESULTS

Three hundred and nineteen PEG patients were found. One hundred and sixty-eight males and 151 females with mean body mass index 28.47 ± 9.75 kg/m² and mean age 65.03 ± 16.11 years were identified. Thirty-three patients were on clopidogrel prior to PEG with 286 patients not on clopidogrel. No patients in either group developed hematochezia, melena, or hematemesis within 48 h of percutaneous endoscopic gastrostomy (PEG). No statistical differences were observed between the two groups with 48 h for hemoglobin decrease of > 2 g/dL (2 vs 5 patients; P = 0.16), blood transfusions (2 vs 7 patients; P = 0.24), and repeat endoscopy for possible gastrointestinal bleeding (no patients in either group).

CONCLUSION

Based on the results, no significant post-procedure bleeding was observed in patients undergoing PEG with recent use of clopidogrel.

A Clinician's Guide to Fecal Occult Blood Testing for Colorectal Cancer

Colorectal cancer (CRC) is a significant healthcare issue, with substantial morbidity and mortality. Screening for CRC is essential in the prevention and treatment of this disease. The two most common CRC screening modalities are colonoscopy and the stool-based occult blood test, with two types of stool-based occult blood tests: the guaiac-based fecal occult blood test (FOBT) and the immunochemical FOBT. Despite many similarities, these two stool tests are different and often are confused in clinical practice. In an effort to improve awareness of these testing modalities, this review provides extensive information on both of these FOBTs, as well as discusses comparisons in the literature between these stool-based blood tests and other screening modalities such as stool DNA and colonoscopy.

Prophylactic clipping and post-polypectomy bleeding: a meta-analysis and systematic review

BACKGROUND

Bleeding after polypectomy is a common issue associated with colonoscopy. To help prevent post-polypectomy bleeding, many endoscopists place clips at the site. However, this practice remains controversial. Therefore, we performed a meta-analysis of the efficacy of clip placement in the prevention of post-polypectomy bleeding.

METHODS

Multiple databases, including Embase, Scopus, MEDLINE/PubMed, CINAHL, Cochrane databases, and recent abstracts from major American meetings were searched in April 2016. Using the DerSimonian and Laird (random effects) model with odds ratio (OR), a meta-analysis was performed of post-polypectomy bleeding with prophylactic clip versus no prophylactic clip.

RESULTS

Five hundred and thirty potential articles and abstracts were discovered. Thirty-five articles were reviewed, with 12 studies satisfying the inclusion criteria. No statistically significant difference in prophylactic clipping versus no prophylactic clipping for post-polypectomy bleeding in all polyps was found when all studies (OR 1.49; 95% CI: 0.56-4.00; P=0.42), only peer-reviewed studies where abstracts were excluded (OR 0.84; 95% CI: 0.42-1.69; P=0.63), and only randomized controlled trials (OR 1.24; 95% CI: 0.69-2.24; P=0.47) were analyzed.

CONCLUSIONS

The use of prophylactic clipping for all polypectomies does not seem to prevent post-polypectomy bleeding and should not be a routine practice. However, for large polyps (>2 cm), prophylactic clipping may or may not be beneficial in preventing post-polypectomy bleeding. Further studies are required to fully evaluate this subgroup.

Pre-endoscopic erythromycin administration in upper gastrointestinal bleeding: an updated meta-analysis and systematic review

Background

In patients suffering from upper gastrointestinal bleeding (UGIB), adequate visualization is essential during endoscopy. Prior to endoscopy, erythromycin administration has been shown to enhance visualization in these patients; however, guidelines have not fully adopted this practice. Thus, we performed a comprehensive, up-to-date meta-analysis on the issue of erythromycin administration in this patient population.

Methods

After searching multiple databases (November 2015), randomized controlled trials on adult subjects comparing administration of erythromycin before endoscopy in UGIB patients to no erythromycin or placebo were included. Pooled estimates of adequacy of gastric mucosa visualized, need for second endoscopy, duration of procedure, length of hospital stay, units of blood transfused, and need for emergent surgery using odds ratio (OR) or mean difference (MD) were calculated. Heterogeneity and publication bias were assessed.

Results

Eight studies (n=598) were found to meet the inclusion criteria. Erythromycin administration showed statistically significant improvement in adequate gastric mucosa visualization (OR 4.14; 95% CI: 2.01-8.53, P<0.01) while reduced the need for a second-look endoscopy (OR 0.51; 95% CI: 0.34-0.77, P<0.01) and length of hospital stay (MD -1.75; 95% CI: -2.43 to -1.06, P<0.01). Duration of procedure (P=0.2), units of blood transfused (P=0.08), and need for emergent surgery (P=0.88) showed no significant differences.

Conclusion

Pre-endoscopic erythromycin administration in UGIB patients significantly improves gastric mucosa visualization while reducing length of hospital stay and the need for second-look endoscopy.

Optimizing bowel preparation for colonoscopy: a guide to enhance quality of visualization

Colonoscopy is an important screening and therapeutic modality for colorectal cancer. Unlike other screening tests, colonoscopy is dependent on pre-procedure bowel preparation. If the bowel preparation is poor, significant pathology may be missed. Many factors are known to improve bowel preparation. This review will highlight those factors that may optimize the bowel preparation, including choice of bowel preparation, grading or scoring of the bowel preparation, special factors that influence preparation, and diet prior to colonoscopy that affects bowel preparation. The aim of the review is to offer suggestions and guide endoscopists on how to optimize the bowel preparation for the patients undergoing colonoscopy.

Low-residue versus clear liquid diet before colonoscopy: a meta-analysis of randomized, controlled trials

BACKGROUND AND AIMS

Colonoscopy is extremely important for the identification and removal of precancerous polyps. Bowel preparation before colonoscopy is essential for adequate visualization. Traditionally, patients have been instructed to consume only clear liquids the day before a colonoscopy. However, recent studies have suggested using a low-residue diet, with varying results. We evaluated the outcomes of patients undergoing colonoscopy who consumed a clear liquid diet (CLD) versus low-residue diet (LRD) on the day before colonoscopy by a meta-analysis.

METHODS

Scopus, PubMed/MEDLINE, Cochrane databases, and CINAHL were searched (February 2015). Studies involving adult patients undergoing colonoscopy examination and comparing LRD with CLD on the day before colonoscopy were included. The analysis was conducted by using the Mantel-Haenszel or DerSimonian and Laird models with the odds ratio (OR) to assess adequate bowel preparations, tolerability, willingness to repeat diet and preparation, and adverse effects.

RESULTS

Nine studies (1686 patients) were included. Patients consuming an LRD compared with a CLD demonstrated significantly higher odds of tolerability (OR 1.92; 95% CI, 1.36-2.70; P < .01) and willingness to repeat preparation (OR 1.86; 95% CI, 1.34-2.59; P < .01) with no differences in adequate bowel preparations (OR 1.21; 95% CI, 0.64-2.28; P = .58) or adverse effects (OR 0.88; 95% CI, 0.58-1.35; P = .57).

CONCLUSION

An LRD before colonoscopy resulted in improved tolerability by patients and willingness to repeat preparation with no differences in preparation quality and adverse effects.

Nasal bridles for securing nasoenteric tubes: a meta-analysis

BACKGROUND

Nasoenteric feeding tubes may easily become dislodged due to patient mental status, transfers, or positional changes. Nasal bridles were introduced to provide a better, more reliable system to secure these tubes. This meta-analysis was performed to evaluate the effectiveness of nasal bridles compared with the traditional method of adhesive tape alone in securing enteral feeding tubes.

MATERIALS AND METHODS

Multiple databases were searched (October 2013). All studies that evaluated the use of nasal bridles in adult patients were included in the analysis. Meta-analysis for the outcomes from use of a nasal bridle vs the more traditional method of adhesive tape alone for securing nasoenteric tubes was analyzed by calculating pooled estimates of dislodgement, skin complications, and sinusitis. Statistical analysis was performed using RevMan 5.1.

RESULTS

Six studies (n = 594) met the inclusion criteria. Use of a nasal bridle for securing enteral tubes resulted in a statistically significant reduction in tube dislodgement compared with traditional adhesive tape alone (odds ratio [OR], 0.16; 95% confidence interval [CI], 0.10–0.27; P < .01). The use of nasal bridles was associated with a higher rate of skin complications compared with traditional adhesive tape (OR, 4.27; 95% CI, 1.79–10.23; P < .01). Incidence of sinusitis was no different between the 2 groups (OR, 0.26; 95% CI, 0.03–2.28; P = .22).

CONCLUSION

Nasal bridles appear to be more effective at securing nasoenteric tubes and preventing dislodgement than traditional use of tape alone.

Effect of Immunosuppressive Therapies for the Treatment of Inflammatory Bowel Disease on Response to Routine Vaccinations: A Meta-Analysis

BACKGROUND

Several studies have evaluated the effect of immunosuppressive therapy for the treatment of inflammatory bowel disease (IBD) on response to routine vaccinations. The overall effect of specific classes of medications (i.e., immunomodulator vs. biologics) on vaccine response remains undefined. The aim of this study was to determine the effect of each class of immunosuppressive therapy in IBD patients on response to routine vaccinations.

METHODS

A comprehensive search of PubMed/MEDLINE, Scopus, CINAHL, and Cochrane databases was performed (December 2014). All studies on adults comparing vaccine response among IBD patients on immunosuppression with non-immunosuppressed patients were included. Meta-analysis was performed using the Mantel-Haenszel (fixed effects) model with odds ratio (OR) to assess for adequate vaccine response.

RESULTS

In the pooled analysis of nine studies (N = 1474), we found that there was nearly a 60 % lower chance of achieving adequate seroprotection in the group that received immunosuppressive therapy compared to the group that was not on any immunosuppressive therapies (OR 0.41 95 % CI 0.30, 0.55, p < 0.001). Specifically, we also demonstrated that patients on immunomodulator monotherapy had a twofold higher probability of achieving adequate immune response to vaccination, compared to patients on anti-tumor necrosis factor (anti-TNF) monotherapy (OR 1.92 95 % CI 1.30, 2.84).

CONCLUSION

In conclusion, IBD patients on immunosuppressive therapy have a significantly lower response to routine vaccinations. The greatest effect is seen among patients on anti-TNF and combination immunosuppressive therapy. Routine monitoring of vaccine titers post-vaccination is important to ensure that adequate immunologic response has been achieved among IBD patients.

Specialized enteral nutrition therapy in Crohn's disease patients on maintenance infliximab therapy: a meta-analysis

OBJECTIVES

Many patients with Crohn's disease on infliximab maintenance therapy have recurrent symptoms despite an initial clinical response. Therefore, concomitant therapies have been studied. We conducted a meta-analysis to assess the effect of specialized enteral nutrition therapy with infliximab versus infliximab monotherapy in patients with Crohn's disease.

METHODS

A comprehensive search of multiple databases was performed. All studies of adult patients with Crohn's disease comparing specialized enteral nutrition therapy (elemental or polymeric diet with low-fat or regular diet) with infliximab versus infliximab monotherapy without dietary restrictions were included. Meta-analysis was performed using the Mantel-Haenszel (fixed effect) model with odds ratio (OR) to assess for clinical remission.

RESULTS

Four studies (n = 342) met inclusion criteria. Specialized enteral nutrition therapy with infliximab resulted in 109 of 157 (69.4%) patients reaching clinical remission compared with 84 of 185 (45.4%) with infliximab monotherapy [OR 2.73; 95% confidence interval (CI): 1.73-4.31, p < 0.01]. Similarly, 79 of 106 (74.5%) patients receiving enteral nutrition therapy and infliximab remained in clinical remission after one year compared with 62 of 126 (49.2%) patients receiving infliximab monotherapy (OR 2.93; 95% CI: 1.66-5.17, p < 0.01). No publication bias or heterogeneity was noted for either outcome.

CONCLUSIONS

The use of specialized enteral nutrition therapy in combination with infliximab appears to be more effective at inducing and maintaining clinical remission among patients with Crohn's disease than infliximab monotherapy.

pANCA positivity predicts lower clinical response to infliximab therapy among patients with IBD

OBJECTIVES

Several studies have been performed evaluating the role of perinuclear anti-neutrophil cytoplasmic antibodies (pANCA) to predict early clinical response among patients with inflammatory bowel disease (IBD) who are undergoing infliximab therapy. The results of these studies are variable, however, and the effect of pANCA+ as a predictor of clinical response to infliximab remains largely undefined. The goal of this meta-analysis was to evaluate the role of pANCA in predicting poor responders to infliximab.

METHODS

A comprehensive search of the PubMed/MEDLINE, Scopus, Cumulative Index of Nursing and Allied Health Literature, Google Scholar, and Cochrane databases was performed in June 2014. All of the studies that evaluated pANCA levels in patients with IBD who were undergoing antitumor necrosis factor-α (anti-TNF-α) therapy and their clinical responses were included. A meta-analysis was performed using the Mantel-Haenszel model with odds ratios to assess for clinical remission.

RESULTS

In the pooled analysis (N = 415), patients who were pANCA negative had nearly a twofold higher response to anti-TNF-α therapy compared with patients who were pANCA+ (odds ratio 1.87; 95% confidence interval 1.02-3.41). Serologic testing for pANCA+ predicting nonresponse to infliximab therapy showed a sensitivity of 25.2%, a specificity of 85.5%, a positive predictive value of 41.1%, and a negative predictive value of 74.0%.

CONCLUSIONS

Being more proactive (ie, early dose escalation or accelerated loading regimen) in patients who are pANCA+ may be necessary to improve clinical response.

Optimizing the use of anti-tumor necrosis factor in the management of patients with Crohn's disease

Since the approval of the first anti-tumor necrosis factor (anti-TNF) therapy in late 1998, the treatment for Crohn's disease (CD) has been revolutionized. Anti-TNF therapy has been consistently shown in numerous clinical trials to be effective for patients with more aggressive perianal, internal penetrating, and fistulizing CD. However, the loss of clinical remission is frequent and only one-third of patients remain in clinical remission at 1 year. The pharmacokinetics of anti-TNF is highly variable among patients and could be influenced by many factors including serum albumin, gender, body weight, systemic inflammation and route of administration. The main factor impacting anti-TNF pharmacokinetics and efficacy is the development of immunogenicity where antidrug antibodies accelerate anti-TNF drug clearance. In this review paper, we evaluate the role of combination therapy with anti-TNF drugs and immunomodulators, the role of therapeutic drug monitoring, and strategies to recapture loss of clinical response in order to improve both short- and long-term outcomes in CD patients.

Success of endoscopic ultrasound-guided ethanol ablation of pancreatic cysts: a meta-analysis and systematic review

BACKGROUND

Endoscopic ultrasound (EUS)-guided ethanol ablation has emerged as an efficacious and safe alternative management option for pancreatic cysts. We undertook a meta-analysis and systematic review to assess the overall safety and efficacy of EUS-guided ethanol ablation of pancreatic cysts.

METHOD STUDY SELECTION CRITERIA

EUS-guided ethanol ablation of pancreatic cysts.

DATA COLLECTION EXTRACTION

Articles were searched in Medline, Pubmed, and Ovid journals.

STATISTICAL METHOD

Fixed and random effects models were used to calculate the pooled proportions.

RESULTS

Initial search identified 1,319 reference articles, in which 120 relevant articles were selected and reviewed. Data was extracted from seven studies (n = 152) of EUS-guided ethanol ablation of pancreatic cysts, which met the inclusion criteria. With EUS-guided ethanol ablation, the pooled proportion of patients with complete cyst resolution was 56.20 % (95 % CI = 48.16 to 64.08) and partial cyst resolution was 23.72 % (95 % CI = 17.24 to 30.89). Postprocedural complications after ablation were significant for abdominal pain in 6.51 % (95 % CI = 3.12 to 11.04) and pancreatitis in 3.90 % (95 % CI = 1.39 to 7.60) of the pooled percentage of patients. Publication bias calculated using Harbord-Egger bias indicator gave a value of -1.09 (95 % CI = 10.21 to 8.03, p = 0.77). The Begg-Mazumdar indicator gave a Kendall's tau b value of 0.05 (p ≥ 0.99).

CONCLUSIONS

EUS-guided ethanol ablation may be a safe alternative treatment modality for pancreatic cysts, with acceptable intraprocedural and postprocedural complications. However, due to the limited data available, prospective randomized controlled trials with a long follow up period are required in this area.

Prophylactic tracheal intubation for upper GI bleeding: A meta-analysis

AIM: To evaluate usefulness of prophylactically intubating upper gastrointestinal bleeding (UGIB) patients.

METHODS: UGIB results in a significant number of hospital admissions annually with endoscopy being the key intervention. In these patients, risks are associated with the bleeding and the procedure, including pulmonary aspiration. However, very little literature is available assessing the use of prophylactic endotracheal intubation on aspiration in these patients. A comprehensive search was performed in May 2014 in Scopus, CINAHL, Cochrane databases, PubMed/Medline, Embase, and published abstracts from national gastroenterology meetings in the United States (2004-2014). Included studies examined UGIB patients and compared prophylactic intubation to no intubation before endoscopy. Meta-analysis was conducted using RevMan 5.2 by Mantel-Haenszel and DerSimonian and Laird models with results presented as odds ratio for aspiration, pneumonia (within 48 h), and mortality. Funnel plots were utilized for publication bias and I² measure of inconsistency for heterogeneity assessments.

RESULTS: Initial search identified 571 articles. Of these articles, 10 relevant peer-reviewed articles in English and two relevant abstracts were selected to review by two independent authors (Almashhrawi AA and Bechtold ML). Of these studies, eight were excluded: Five did not have a control arm, one was a letter the editor, one was a survey study, and one was focused on prevention of UGIB. Therefore, four studies (N = 367) were included. Of the UGIB patients prophylactically intubated before endoscopy, pneumonia (within 48 h) was identified in 20 of 134 (14.9%) patients as compared to 5 of 95 (5.3%) patients that were not intubated prophylactically (P = 0.02). Despite observed trends, no significant differences were found for mortality (P = 0.18) or aspiration (P = 0.11).

CONCLUSION: Pneumonia within 48 h is more likely in UGIB patients who received prophylactic endotracheal intubation prior to endoscopy.

The pharmacologic treatment of short bowel syndrome: new tricks and novel agents

Short bowel syndrome (SBS) is a manifestation of massive resection of the intestines resulting in severe fluid, electrolyte, and vitamin/mineral deficiencies. Diet and parenteral nutrition play a large role in the management of SBS; however, pharmacologic options are becoming more readily available. These pharmacologic agents focus on reducing secretions and stimulating intestinal adaptation. The choice of medication is highly dependent on the patient's symptoms, remaining anatomy, and risk versus benefit profile for each agent. This article focuses on common and novel pharmacologic medications used in SBS, including expert advice on their indications and use.

Does alvimopan enhance return of bowel function in laparoscopic gastrointestinal surgery? A meta-analysis

BACKGROUND

Postoperative ileus (POI) remains a major impediment in patient recovery and leads to longer lengths of stay at the hospital, readmission rates, and hospital costs. Alvimopan, a mu-opioid receptor antagonist, lowers POI incidence following open gastrointestinal surgery, however, little is known about its role on POI prevention among patients undergoing laparoscopic gastrointestinal surgery.

METHODS

A comprehensive search of PubMed/MEDLINE, Scopus, CINAHL, and Cochrane databases was performed (December 2014). Meta-analysis was performed using the Mantel-Haenszel (fixed effects) model with odds ratio (OR) to assess prevention of POI and hospital readmission.

RESULTS

Five studies were included in the final analysis. Pooling 4 of 5 studies, there was over a 75% relative risk reduction in POI development when patients were given alvimopan compared to placebo (OR 0.24, 95%CI 0.12-0.51, P=0.02). The number needed to treat with alvimopan to prevent one POI episode was 11 patients. There was a modest reduction in the length of hospitalization between 0.2 and 1.6 days. There did not appear to be a difference in frequency of 30-day readmission rate among the alvimopan group compared to placebo (OR 1.15, 95%CI 0.54-2.45, P=0.62).

CONCLUSION

Overall, there was a 75% relative risk reduction in POI development among patients undergoing laparoscopic gastrointestinal surgery. However, there did not appear to be a significant reduction in all-cause 30-day readmission rate or length of hospitalization. Future studies will need to address which subset of patients undergoing laparoscopic gastrointestinal surgery will benefit most from alvimopan.

Airway assessment of patients undergoing endoscopic procedures

OBJECTIVES

In advance of endoscopic procedures, an evaluation to assess the risk of sedation is performed by the gastroenterologist. Based on regulations, gastroenterologists are required to perform an airway assessment. At this time, data supporting this regulation are limited; therefore, we evaluated airway assessment accuracy by gastroenterologists before endoscopic procedures.

METHODS

A retrospective, single tertiary care center study was performed from May 2012 through August 2013. Patients who underwent an endoscopy or colonoscopy performed at the University of Missouri-Columbia with documented Mallampati scores were included in the analysis. Three primary cohorts of patients were included in our study: gastroenterologist versus anesthesiologist, gastroenterologist versus other gastroenterologists, and gastroenterologists versus themselves. Data were collected and recorded for patient age, body mass index, and Mallampati score. Statistical analysis was performed using descriptive statistics and linear weighted kappa analysis for agreement.

RESULTS

For gastroenterologists versus anesthesiologists and versus other gastroenterologists, the agreement on Mallampati scores was poor (weighted kappa index 0.103, 95% confidence interval [CI] -0.0126 to 0.219; percentage of agreement 42% and 0.120, 95% CI -0.0211 to 0.260; percentage of agreement 46%, respectively). For gastroenterologists versus themselves for the same patient, the agreement on Mallampati scores was only moderate (weighted kappa index 0.420, 95% CI 0.119-0.722; percentage of agreement 65%).

CONCLUSIONS

Gastroenterologists performing a preprocedure assessment using Mallampati scores have poor agreement with anesthesiologists and colleagues and only moderate agreement with themselves.

Hyoscine for polyp detection during colonoscopy: A meta-analysis and systematic review

AIM: To assess the role of hyoscine for polyp detection during colonoscopy.

METHODS: Studies (randomized controlled trials or RCTs) that compared the use of hyoscine vs no hyoscine or placebo for polyp detection during colonoscopy were included in our analysis. A search on multiple databases was performed in September 2013 with search terms being “hyoscine and colonoscopy”, “hyoscine and polyp”, “hyoscine and adenoma”, “antispasmotic and colonoscopy”, “antispasmotic and adenoma”, and “antispasmotic and polyp”. Jadad scoring was used to assess the quality of studies. The efficacy of hyoscine was analyzed using Mantel-Haenszel model for polyp and adenoma detection with odds ratio (OR). The I² measure of inconsistency was used to assess heterogeneity (P < 0.05 or I² > 50%). Statistical analysis was performed by RevMan 5.1. Funnel plots was used to assess publication bias.

RESULTS: The search of the electronic databases identified 283 articles. Of these articles, eight published RCTs performed at various locations in Europe, Asia, and Australia were included in our meta-analysis, seven published as manuscripts and one published as an abstract (n = 2307). All the studies included patients with a hyoscine and a no hyoscine/placebo group and were of adequate quality (Jadad score ≥ 2). Eight RCTs assessed the polyp detection rate (PDR) (n = 2307). The use of hyoscine demonstrated no statistically significant difference as compared to no hyoscine or placebo for PDR (OR = 1.06; 95%CI: 0.89-1.25; P = 0.51). Five RCTs assessed the adenoma detection rate (ADR) (n = 2015). The use of hyoscine demonstrated no statistically significant difference as compared to no hyoscine or placebo for ADR (OR = 1.12; 95%CI: 0.92-1.37; P = 0.25). Furthermore, the timing of hyoscine administration (given at cecal intubation or pre-procedure) demonstrated no differences in PDR compared to no hyoscine or placebo. Publication bias or heterogeneity was not observed for any of the outcomes.

CONCLUSION: Hyoscine use in patients undergoing colonoscopy does not appear to significantly increase the detection of polyps or adenomas.

Improving care access for new patients in an outpatient gastroenterology clinic: a novel approach

BACKGROUND

We performed a quality initiative to improve our gastroenterology clinic access.

METHODS

A prospective quality improvement initiative was implemented in 12/2012.

RESULTS

From 10/2011-11/2012, 35.1% new patients were seen < or =10 days. After initiation of the quality improvement initiatives from 12/2012-1/2014, 75.2% new patients were seen < or =10 days (p<0.01).

CONCLUSION

New patient access to subspecialty clinics can be improved with simple initiatives, staff education, and improved teamwork.

Tips and tricks for deep jejunal enteral access: modifying techniques to maximize success

Endoscopic insertion of enteral feeding tubes is a major advance in the delivery of nutrition therapy. Since the first report of percutaneous endoscopic gastrostomy (PEG) in 1980 (Gauderer et al. J Pediatr Surg. 15:872-5, 1980), insertion techniques and equipment have been refined and improved. Despite this progress, deep jejunal enteral access remains a difficult procedure, and many endoscopists do not have experience with the techniques of nasojejunal (NJ) placement, percutaneous endoscopic gastrojejunostomy (PEGJ), or direct percutaneous endoscopic jejunostomy (DPEJ) (Shike and Latkany, Gastrointest Endosc Clin N Am. 8:569-80, 1998). The difference between an exasperating experience and a rewarding procedure lies in mastering the "tips and tricks" that make insertion easy. While the basic techniques are described elsewhere (McClave and Chang 2011), we review several universal basic principles to enhance deep jejunal access, which should promote a more efficient and successful procedure.

National trends and inpatient outcomes of inflammatory bowel disease patients with concomitant chronic liver disease

BACKGROUND

There is little information on the frequency of chronic liver disease among hospitalized patients with inflammatory bowel disease (IBD). In this study, we seek to define the common etiologies contributing to chronic liver disease among IBD patients and to identify potential risk factors predictive of increased mortality in this population.

METHODS

We analyzed the Nationwide Inpatient Sample from 1988 to 2006 to determine the frequency of chronic liver disease among patients with IBD and to determine their in-hospital outcomes.

RESULTS

From 1988 to 2006, the age-adjusted rate of chronic liver disease among hospitalized patients with IBD has increased from 4.35 per 100,000 persons in 1988-2001 to 7.45 per 100,000 persons in 2004-2006. The most common etiologies contributing to chronic liver disease among IBD patients were: primary sclerosing cholangitis, unspecified chronic hepatitis, chronic hepatitis C, and nonalcoholic fatty liver disease. Compared to IBD patients without liver disease, there was more than a twofold higher rate of inpatient morality among IBD patients with concomitant liver disease (2.7% vs. 1.3%, p < 0.01). The multivariate analysis showed that factors predictive of inpatient mortality include age >50, spontaneous bacterial peritonitis, ascites, hepatic encephalopathy, presence of cirrhosis, malnutrition, Clostridium difficile colitis, and hospital-acquired pneumonia.

CONCLUSION

There is a higher rate of inpatient mortality among patients with concomitant IBD and chronic liver disease compared to IBD alone. Early recognition and management of complications related to portal hypertension among patients with IBD and chronic liver disease is particularly important in order to reduce inpatient mortality and morbidity.

Weekday vs weekend endoscopy: Is there a true difference in patient outcomes? A meta-analysis

AIM: To evaluate the “weekend effect” on outcomes in patient admitted on the weekend for upper gastrointestinal bleeding (UGIB).

METHODS: A comprehensive search was performed (March 2014). Studies comparing weekend and weekday endoscopy in patients with UGIB were included. All studies had at least 2 of 3 primary outcomes which included: mortality, need for surgery, time to endoscopy, endoscopy on admission day, and length of hospital stay. Three authors individually extracted data. Meta-analysis was performed using pooled estimates with odds ratio or mean difference by fixed and random effects models.

RESULTS: Eleven studies met the inclusion criteria. Patients admitted with UGIB on the weekend exhibited a statistically significant increase in mortality (OR = 1.13; 95%CI: 1.06-1.20; P < 0.01), need for surgery (OR = 2.46; 95%CI: 1.51-3.99; P < 0.01), and time to endoscopy (MD 2.68; 95%CI: 0.17-5.20; P = 0.04) as compared to patients admitted with UGIB on a weekday. Furthermore, patients with UGIB admitted on weekend experienced statistically significant less endoscopy on day of admission (OR = 0.72; 95%CI: 0.62-0.85; P < 0.01). No difference was noted between the two groups for length of hospital stay (MD -1.29; 95%CI: -3.03-0.45; P = 0.15).

CONCLUSION: A weekend effect seems to be apparent in patients with UGIB with significantly poorer outcomes.
