RESUMO
Introduction The risk of inflammatory bowel disease-associated colorectal cancer (IBD-CRC) is known to increase with primary sclerosing cholangitis (PSC) and a family history of CRC. However, the impact of comorbidities such as liver disease, obesity, diabetes, chronic lung, heart, and renal disease, and psychiatric illness on the risk of IBD-CRC remains unclear. We evaluated the effect of these comorbidities on the risk of IBD-CRC. Methods A retrospective review from 2009 to 2014 was conducted using the National Inpatient Sample data for adults 18 years and older. Patients with IBD (360,892), of whom 2,831 had CRC were identified using the International Classification of Diseases, Ninth Revision codes (ICD-9). Data on comorbidities were also obtained. Adjusted odds ratios (aOR) and confidence intervals (CI) were computed via logistic regression to evaluate the effect of comorbidities on the risk of IBD-CRC; the p-value was set at <0.05. Results The mean age of IBD patients in this study was 52.36±0.03. A majority of the patients with IBD-CRC were white and were significantly older compared to those without cancer (60 vs 52 years, p<0.05). The risk of colon cancer in IBD was increased by having a non-cholestatic liver disease (aOR 1.51, CI 1.23-1.86, p<0.01). Also, patients younger than 50 years with liver disease were at an increased risk of IBD-associated colon cancer in comparison to older patients (aOR 1.83 vs 1.34, p<0.05). Notably, diabetes, chronic pulmonary disease, renal failure, psychiatric illnesses, and rheumatoid diseases, were inversely associated with the risk of IBD-CRC (p<0.05). After stratifying by IBD subtypes, non-cholestatic liver disease was still independently associated with a higher risk for colon cancer in patients with ulcerative colitis or Crohn's disease (ulcerative colitis: aOR 1.43, CI 1.08-1.89; Crohn's disease: aOR 1.46, CI 1.10-2.00). Conclusions Patients with IBD who have non-cholestatic liver disease might have a higher risk for colon cancer, even at a younger age. These patients may require close colon cancer surveillance.
RESUMO
Introduction Primary biliary cholangitis (PBC) is associated with an increased risk of developing fractures. Current guidelines recommend measures that can help prevent the development of fractures in these patients. The purpose of this study was to trend the rates of hospitalizations related to fractures and their burden on healthcare. Methods We performed a retrospective, cohort study of adults hospitalized in the United States with PBC between 2010 and 2014. Patients were identified using the Nationwide Inpatient Sample (NIS). Temporal analysis of PBC patients with a co-diagnosis of hip, vertebral, or wrist fractures (the study group) was performed with regards to the total number of inpatient admissions, inpatient mortality, length of stay, and total charges associated with hospitalization. Descriptive analyses were performed using the t-test for continuous data and the chi-square test for categorical data. Results During the five-year study period, there were 308,753 hospitalizations for PBC. There has been a downward trend (p=0.02) in fracture-related admissions among patients with PBC during this study period. Length of stay was higher in the PBC-fracture group (10.85 days vs 7.36 days; p<0.001). Total hospitalization charges were higher among the PBC-fracture patients when compared to the control group ($98,444 vs $72,964; p=0.004). Conclusion There has been a gradual reduction in the rate of fracture-related hospitalizations in patients with PBC. However, patients with PBC who have fractures have increased the utilization of health care resources as compared to their cohort admitted for reasons other than for a fracture.
RESUMO
Endoscopic cystogastrostomy using lumen-apposing metal stent (LAMS) is considered the first-line therapy for symptomatic pancreatic fluid collections (PFCs). Routine coaxial placement of a double-pigtail stent (DPS) through LAMS is debated. We report the case of a patient with delayed massive gastrointestinal bleed eight weeks after LAMS placement due to splenic artery pseudoaneurysm leading to a complicated hospitalization. Theoretically, coaxial placement of DPS through LAMS can prevent the relatively sharp LAMS from eroding into the mucosa of the collapsed cavity of PFCs, decreasing the risk of bleeding. Our case adds to the growing need to further explore the utility of this combined intervention.
RESUMO
Gastrointestinal bleeding (GIB) is a common cause of hospitalization and is associated with significant morbidity and mortality. The most frequent causes of nonvariceal upper GIB are peptic ulcers, mucosal erosions, Mallory-Weiss tears, and malignancy. Current endoscopic hemostatic methods, including injections, thermal and mechanical modalities, have a 5%-10% chance of recurrent bleeding. Hemospray (Cook Medical, Winston-Salem, NC, USA) is a recently approved modality and can help treat tumor-related GIB. We present a case of a patient with diffuse large B-cell gastric lymphoma who presented with tumor-related GIB. His clinical course was complicated by gastric perforation and active bleeding which was treated with Hemospray and over-the-scope clips (OTSC, Ovesco, Tübingen, Germany).
RESUMO
Over-the-scope clips (OTSC) (Ovesco, Tübingen, Germany) are commonly used for closure of bowel perforations, fistulas and to achieve hemostasis. This device is attached to the endoscope and delivers a variety of clips, based on diameter and depth, that works through tissue approximation. Complications including local inflammation, ulcers, or obstruction can occur. When the clip is misplaced or OTSC-associated complications occur, OTSC removal may be indicated. We present a case of a patient who presented to our hospital with upper gastrointestinal (GI) bleeding. OTSC was used to achieve hemostasis, however, the clip was misplaced over the ampulla of Vater. remOVE system (Ovesco, Tübingen, Germany) was used to remove the misplaced clip.
RESUMO
Mucormycosis is a rare and life-threatening fungal infection that is associated with high mortality in immunocompromised individuals. Although it most commonly affects lungs and paranasal sinuses, cases of invasive mucormycosis of the gastrointestinal tract have also been reported. Gastrointestinal mucormycosis (GIM) is most commonly found in the stomach, colon, and ileum. Etiologies of GIM include ingestion of spores and penetrating abdominal trauma, causing mucocutaneous disruption. We present a case of an immunocompetent man who presented to our hospital after a gunshot wound to the abdomen. His hospital course was complicated with the development of invasive GIM in the form of a large gastric ulcer, which caused gastrointestinal bleeding and eventually perforation.
RESUMO
Pancreatic fluid collections occur in 5%-15% of acute complicated pancreatitis cases. Endoscopic drainage using lumen-apposing metal stents has become the treatment of choice with less incidence of complications, shorter hospital stays, and less cost. The AXIOS stent has proven to be safe and effective in several studies. Despite a low complication rate, bleeding, perforation, and stent migration were still reported. In this case, a patient presented for delayed AXIOS stent removal and was found to have stent migration with embedment in the gastric wall. The transmural defect that resulted after endoscopic stent removal was observed to close spontaneously without further need for intervention.
RESUMO
Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related death and one of the most prevalent cancers worldwide. HCC prognosis remains poor with an average survival rate between 6 and 12 months. Obstructive jaundice, as a main clinical feature, is uncommon in HCC. HCC with bile duct invasion is much rarer than HCC with vascular invasion. We present a case where a patient's HCC was diagnosed by endoscopic retrograde cholangiopancreatography and digital cholangioscopy because his HCC manifested as an obstructing lesion in the intrahepatic duct, but not in the liver.
RESUMO
Acute upper and lower gastrointestinal bleeding, enteral feeding, cecostomy tubes and luminal strictures are some of the common reasons for gastroenterology service. While surgery was initially considered the main treatment modality, the advent of both therapeutic endoscopy and interventional radiology have resulted in the paradigm shift in the management of these conditions. In this paper, we discuss the patient's work up, indications, and complementary roles of endoscopic and angiographic management in the settings of gastrointestinal bleeding, enteral feeding, cecostomy tube placement and luminal strictures. These conditions often require multidisciplinary approaches involving a team of interventional radiologists, gastroenterologists and surgeons. Further, the authors also aim to describe how the fields of interventional radiology and gastrointestinal endoscopy are overlapping and complementary in the management of these complex conditions.
RESUMO
Recent studies have revealed that deep pancreatic duct wire passage, even in the absence of contrast injection, is a major technique-related culprit in post-ERCP pancreatitis, unless followed by placement of a pancreatic stent. As guidewire cannulation becomes increasingly widespread, precise control of the guidewire is thus critical. The first randomized trial to compare endoscopist-controlled wire guided vs. assistant-controlled bile duct cannulation has shown a significant reduction in post ERCP pancreatitis when the physician manipulates the wire. Though there is no single universal solution to post-ERCP pancreatitis, careful attention to wire contol is emerging as an important aspect of safety in ERCP.

The diagnosis and staging of various gastrointestinal malignancies have been made possible with the use of endoscopic ultrasound, which is a relatively safe procedure. The field of endoscopic ultrasound is fast expanding due to advancements in therapeutic endoscopic ultrasound. Though various studies have established its role in gastrointestinal malignancies and pancreatic conditions, its potential in the field of hepatic lesions still remains vastly untapped. In this paper the authors attempt to review important and landmark trials, case series and case studies involving hepatic applications of endoscopic ultrasound, thus not only providing an overview of utilization of endoscopic ultrasound in various liver conditions but also speculating its future role.

The revised Atlanta classification of acute pancreatitis was adopted by international consensus, and is based on actual local and systemic determinants of disease severity. The local determinant is pancreatic necrosis (sterile or infected), and the systemic determinant is organ failure. Local complications of pancreatitis can include acute peri-pancreatic fluid collection, acute necrotic collection, pseudocyst formation, and walled-off necrosis. Interventional endoscopic ultrasound (EUS) has been increasing utilized in managing these local complications. After performing a PubMed search, the authors manually applied pre-defined inclusion criteria or a filter to identify publications relevant to EUS and pancreatic collections (PFCs). The authors then reviewed the utility, efficacy, and risks associated with using therapeutic EUS and involved EUS devices in treating PFCs. Due to the development and regulatory approval of improved and novel endoscopic devices specifically designed for transmural drainage of fluid and necrotic debris (access and patency devices), the authors predict continuing evolution in the management of PFCs. We believe that EUS will become an indispensable part of procedures used to diagnose PFCs and perform image-guided interventions. After draining a PFC, the amount of tissue necrosis is the most important predictor of a successful outcome. Hence, it seems logical to classify these collections based on their percentage of necrotic component or debris present when viewed by imaging methods or EUS. Finally, the authors propose an algorithm for managing fluid collections based on their size, location, associated symptoms, internal echogenic patterns, and content.

BACKGROUND: Endoscopic necrosectomy for necrotizing pancreatitis has been increasingly used as an alternative to surgical or percutaneous interventions. The use of fully covered esophageal self-expandable metallic stents may provide a safer and more efficient route for internal drainage. The aim of this study was to evaluate the safety and efficacy of endoscopic treatment of pancreatic necrosis with these stents. METHODS: A retrospective study at 2 US academic hospitals included patients with infected pancreatic necrosis from July 2009 to November 2012. These patients underwent transgastric placement of fully covered esophageal metallic stents draining the necrosis. After necrosectomy, patients underwent regular sessions of endoscopic irrigation and debridement of cystic contents. The efficacy endpoint was successful resolution of infected pancreatic necrosis without the need for surgical or percutaneous interventions. RESULTS: Seventeen patients were included with the mean age of 41±12 years. A mean of 5.3±3.4 sessions were required for complete drainage and the follow-up period was 237.6±165 days. Etiology included gallstone pancreatitis (6), alcohol abuse (6), s/p distal pancreatectomy (2), postendoscopic retrograde cholangiopancreatography pancreatitis (1), medication-induced pancreatitis (1), and hyperlipidemia (1). Mean size of the necrosis was 14.8 cm (SD 5.6 cm), ranging from 8 to 19 cm. Two patients failed endoscopic intervention and required surgery. The only complication was a perforation during tract dilation, which was managed conservatively. Fifteen patients (88%) achieved complete resolution. CONCLUSIONS: Endoscopic necrosectomy with covered esophageal metal stents is a safe and successful treatment option for infected pancreatic necrosis.

BACKGROUND: One in every six adults (16.3% of the U.S. adult population) has high total cholesterol levels, and they are at double the risk of heart disease compared with people with optimal levels. OBJECTIVE: To evaluate compliance of internal medicine residents with the latest National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) guidelines in treating patients with hyperlipidemia. DESIGN: Retrospective observational study. SETTING: Ambulatory Clinic, Saint Vincent Hospital, Worcester, Massachusetts. PATIENTS: Patients with a diagnosis of hyperlipidemia who attended the clinic during a 1-ear period, from December 2009 to November 2010. MEASUREMENTS: A review of medical records was conducted to evaluate residents' compliance with the NCEP-ATP III guidelines for LDL cholesterol and non-HDL cholesterol management. RESULTS: Seven hundred seventy charts were reviewed. Only 212 (27.5%) met the inclusion criteria. Analysis of data revealed better compliance with drug therapy (44%-77%) and therapeutic lifestyle changes (44%-83%) when compared with follow-up recommendations (22%-31%). An increase in compliance also was noted in all areas of intervention when patients had an abnormal lipid profile. LIMITATIONS: Compliance was assessed on the basis of electronic medical record documentation alone and hence we may be underestimating compliance with therapeutic lifestyle changes and follow-up recommendations. CONCLUSION: Compliance among internal medicine residents in the diagnosis, treatment and follow-up of patients with hyperlipidemia according to NCEP-ATP III guidelines was suboptimal and needs improvement.

Strictures at the hilum are caused by varied conditions and don't usually become symptomatic until obstructing the bile ducts, thus posing diagnostic and therapeutic challenges to physicians. ERCP is the method of choice for tissue diagnosis and decompression. MRCP or MRI with dedicated liver protocol provides a unique ability to visualize anatomy and promote procedure planning. In patients with unresectable tumor, endoscopic biliary stenting is a palliative approach. Percutaneous or EUS-guided approach is reserved for endoscopic failure. Various new modalities such as radiotherapy, chemotherapy and Photodynamic therapy have emerged but their superiority needs to be confirmed with Randomized Control studies.

Interatrial block (IAB; P-wave duration ≥110 milliseconds) denotes a conduction delay between the two atria. IAB has been shown to have a strong correlation with atrial arrhythmias, left atrial enlargement, left atrial electromechanical dysfunction and cerebral thromboembolism. Our study sought to determine whether there was an increased incidence of IAB in patients with acute occlusive mesenteric ischemia. Medical records of patients admitted with a diagnosis of acute mesenteric ischemia (AMeI) from January 2009 to March 2011 were reviewed retrospectively. One hundred seventy-two out of 342 patients reviewed, qualified after excluding mechanical surgical obstruction, suspected non-occlusive mesenteric ischemia due to shock/hypoperfusion, and mesenteric venous thrombosis. Of 99 patients who were in normal sinus rhythm without prior history of atrial arrhythmia, 88 (88.9 %) had IAB. This was more than twice the average prevalence of IAB of two general hospital populations (41 % and 47 % as demonstrated by two previous studies). IAB may thus represent a novel risk factor for AMeI as it does for embolic stroke.

BACKGROUND: The correlation between vertical P-wave axis (P-axis > 60°) and pulmonary emphysema was investigated on a very large controlled series to see if P-axis verticalisation as lone criterion can be effectively used to screen emphysema in general population. Correlation between degrees of P-axis verticalisation and the severity of the obstructive lung disease (as per global initiative for chronic obstructive lung disease [GOLD] criteria) was also studied to see if this criterion can be used for gross quantification of the chronic obstructive pulmonary disease (COPD) in routine clinical practice. MATERIALS AND METHODS: Around 6500 unselected, routine electrocardiograms (ECGs) were reviewed which yielded 600 ECGs with vertical P-axis in sinus rhythm. 635 ECGs from the same continuum were selected with P-axis ≤60° matched for patient's age and sex serving as controls. Charts were reviewed for the diagnosis of COPD and emphysema based on medical history, pulmonary function tests, and imaging studies. RESULTS: Prevalence of emphysema in patients with vertical P-axis was strikingly higher than in the control group: 85% vs 4.4%. The sensitivity and specificity of vertical P-axis for diagnosing emphysema was 94.76% and 86.47%, respectively. Vertical P-axis and forced expiratory volume (FEV1) were inversely correlated (Pearson correlation coefficient=-0.683). Prevalence of severe COPD was strikingly higher in patients with P-axis > 75° as compared to the group with P-axis 60°-75°: 96.3% vs 4.6%. Close to 80% of the emphysema patients with P-axis > 85° had very severe disease (FEV1 < 30%). CONCLUSION: P-axis verticalisation is highly effective for screening emphysema and degree of verticalisation provides a gross quantification of the disease.
