The telemedicine intervention in chronic disease management promises to involve patients in their own care, provides continuous monitoring by their healthcare providers, identifies early symptoms, and responds promptly to exacerbations in their illnesses. This review set out to establish the evidence from the available literature on the impact of telemedicine for the management of three chronic diseases: congestive heart failure, stroke, and chronic obstructive pulmonary disease. By design, the review focuses on a limited set of representative chronic diseases because of their current and increasing importance relative to their prevalence, associated morbidity, mortality, and cost. Furthermore, these three diseases are amenable to timely interventions and secondary prevention through telemonitoring. The preponderance of evidence from studies using rigorous research methods points to beneficial results from telemonitoring in its various manifestations, albeit with a few exceptions. Generally, the benefits include reductions in use of service: hospital admissions/re-admissions, length of hospital stay, and emergency department visits typically declined. It is important that there often were reductions in mortality. Few studies reported neutral or mixed findings.

Background: The safety and efficacy of bariatric surgery in patients with cirrhosis has not been well studied. Methods: A retrospective review was conducted of patients with cirrhosis who underwent weight-loss surgery at a single institution. Results: Out of a total of 2,119 patients who underwent laparoscopic Roux-en-Y gastric bypass (RYGBP), 30 patients (1.4%) with cirrhosis were identified.When compared with the entire cohort, patients with cirrhosis were significantly more prone to be heavier (BMI 53 vs 48), older in years (age 50 vs 45), more likely to be male (RR=1.3), and have a higher incidence of diabetes (70% vs 21%) and hypertension (67% vs 21%), P<0.05. The diagnosis of cirrhosis was made intra-operatively in 90% of patients. There were no perioperative deaths, conversions to laparotomy, or liver-related complications. Early complications occurred in 9 patients and included anastomotic leak (1), acute tubular necrosis (4), prolonged intubation (2), ileus (1), and blood transfusion (2). Mean length of hospital stay was 4 days (2-18). There was one late unrelated death and one patient with prolonged nausea and protein malnutrition. The average follow-up time was 16 months (1-48). For patients >12 months postoperatively (n=15), the average percent excess weight loss was 63±15%. Conclusion: Laparoscopic RYGBP in the cirrhotic patient has an acceptable complication rate and achieves satisfactory early weight loss. Patients tend to be heavier, older, male and more likely to have diabetes and hypertension. Long-term studies are necessary to examine how weight loss impacts established cirrhosis.

Background: There is no consensus regarding the optimal treatment of ventral hernias in patients who present for weight loss surgery. Methods: Medical records of consecutive morbidly obese patients who underwent laparoscopic Roux-en-Y (LRYGB) gastric bypass with a secondary diagnosis of ventral hernia were reviewed. Only patients who were beyond 6 months of follow-up were included. Results: The study population was 85 patients. There were three groups of patients according to the method of repair: primary repair (59), small intestine submucosa (SIS) (12), and deferred treatment (14). Average follow-up was 26 months. There was a 22% recurrence in the primary repair group. There were no recurrences in the SIS group. Five of the patients in the deferred treatment group (37.5%) presented with small bowel obstruction due to incarceration. Conclusion: Biomaterial mesh (SIS) repair of ventral hernias concomitant with LRYGB resulted in the most favorable outcome albeit having short follow-up. Concomitant primary repair is associated with a high rate of recurrence. All incarcerated ventral hernias should be repaired concomitant with LRYGB, as deferment may result in small bowel obstruction.

BACKGROUND & AIMS Telephone communication is common between healthcare providers and patients with inflammatory bowel disease (IBD). We analyzed telephone activity at an IBD care center to identify disease and patient characteristics associated with high levels of telephone activity and determine if call volume could identify individuals at risk for future visits to the emergency department (ED) or hospitalization. METHODS We performed a prospective observational study in which we categorized telephone calls received by nursing staff over 2 years at a tertiary care IBD clinic (2475 patients in 2009 and 3118 in 2010). We analyzed data on 21,979 ingoing and outgoing calls in 2009 and 32,667 calls in 2010 and assessed associations between clinical factors and logged telephone encounters, and between patterns of telephone encounters and future visits to the ED or hospitalization. RESULTS Telephone encounters occurred twice as frequently as office visits; 15% of the patients generated >10 telephone encounters per year and were responsible for half of all telephone encounters. A higher percentage of these high telephone encounter (HTE) patients were female, had Crohns disease, received steroid treatment, had increased levels of C-reactive protein and rates of erythrocyte sedimentation, had psychiatric comorbidities, and had chronic abdominal pain than patients with lower telephone encounters. The HTE patients were also more frequently seen in the ED or hospitalized over the same time period and in subsequent years. Forty-two percent of patients with >8 telephone encounters within 30 days were seen in the ED or hospitalized within the subsequent 12 months. CONCLUSIONS Based on an analysis of telephone records at an IBD clinic, 15% of patients account for half of all calls. These HTE patients are a heterogeneous group with refractory disease who are likely to visit the ED or be hospitalized.

Technological advancements, along with economic and political issues, have resulted in major changes in surgical education. The development of high fidelity simulators and the widespread availability of the Internet have allowed learning to be shifted away from the operating room. Furthermore, the Internet provides an opportunity for surgical educators to standardize general surgery training and assessment and to develop collaborations nationally and globally. This paper highlights presentations about the challenges as well as the rewards of surgical education in the age of the Internet from the 2009 Academic Surgical Congress.

BackgroundThis study was designed to evaluate the impact of a 2-day laparoscopic bariatric workshop on the practice patterns of participating surgeons.MethodsFrom October 1998 to June 2002, 18 laparoscopic bariatric workshops were attended by 300 surgeons. Questionnaires were mailed to all participants.ResultsResponses were received from 124 surgeons (41%), among whom were 56 bariatric surgeons (open) (45%), 30 advanced laparoscopic surgeons (24%), and 38 surgeons who performed neither bariatric nor advanced laparoscopic surgery (31%). The questionnaire responses showed that 46 surgeons (37%) currently are performing laparoscopic gastric bypass (LGB), 38 (31%) are performing open gastric bypass, and 39 (32%) are not performing bariatric surgery. Since completion of the course, 46 surgeons have performed 8,893 LGBs (mean, 193 cases/surgeon). Overall, 87 of the surgeons (70%) thought that a limited preceptorship was necessary before performance of LGB, yet only 25% underwent this additional training. According to a poll, the respondents thought that, on the average, 50 cases (range, 10–150 cases) are needed for a claim of proficiency.ConclusionLaparoscopic bariatric workshops are effective educational tools for surgeons wishing to adopt bariatric surgery. Open bariatric surgeons have the highest rates of adopting laparoscopic techniques and tend to participate in more adjunctive training before performing LGB. There was consensus that the learning curve is steep, and that additional training often is necessary. The authors propose a mechanism for post-residency skill acquisition for advanced laparoscopic surgery.

Background:Patient-reported Crohns disease (CD) symptoms and endoscopic evaluation have historically guided routine care, but the risk of complications in asymptomatic patients with elevated C-reactive protein (CRP) is unknown. Methods:We conducted a prospective observational cohort study of patients with CD from a tertiary care center. Subjects with short inflammatory bowel disease questionnaire scores ≥50, Harvey–Bradshaw CD scores ⩽4, and same-day CRP measurement were eligible for inclusion. The primary outcome was disease-related hospitalization up to 24 months after the qualifying clinic visit. We assessed the relationship between CRP elevation and subsequent hospitalization. Results:There were 351 asymptomatic patients with CD (median age 40 yr; 50.4% female) who met inclusion criteria, and CRP was elevated in 19.7% of these individuals (n = 69). At 24 months, 16.8% (n = 59) of the study population had been hospitalized for CD-related complications. Significantly, more patients with an elevated CRP were hospitalized (33.3% versus 12.8%, P < 0.0001) compared with those with a normal CRP and were hospitalized at increased rate (P < 0.001) on Kaplan–Meier analysis. CRP elevation was significantly and independently associated with increased risk of hospitalization (adjusted hazard ratio 2.12; 95% confidence interval, 1.13–3.98; P = 0.02) in multivariable survival analysis. Conclusions:Asymptomatic patients with CD with elevated CRP are at a nearly 2-fold higher risk for hospitalization over the subsequent 2 years compared with asymptomatic patients with CD without CRP elevation.

Background:Managing patients with inflammatory bowel disease requires multidisciplinary coordination. Technological advances have enhanced access to care for patients and improved physician interactions. The primary aim of our project was to convene diverse institutions and specialties through a multisite virtual conferencing platform to discuss complex patient management. Methods:The case conference is designed to include multiple institutions to exchange ideas, review evidence-based data, and provide input on the management of patients with Crohns disease and ulcerative colitis. Technology is supplied and coordinated by an information technology specialist and Chorus Call, Inc., an international teleconferencing service provider. The Inflammatory Bowel Disease Live Interinstitutional Interdisciplinary Videoconference Education (IBD LIVE) initiative is accredited by the University of Pittsburgh Medical Center (UPMC) Center for Continuing Education in the Health Sciences for 1 AMA PRA Category 1 Credit per weekly session. Results:IBD LIVE began in 2009 comprising only adult gastroenterology and pediatric gastroenterology from UPMC Presbyterian and Childrens Hospitals. Participation steadily increased from 5 sites in 2010 to 11 sites in 2014. Maximum attendance for a single conference was 73 participants with a median of 48. The Continuing Medical Education scores (1 = worst to 5 = best) have a high median overall score (4.6, range 3.2–5.0) with positive responses with regard to the degree to which the conference changed practice. Conclusions:IBD LIVE has been successful and continues to grow. Implementation of the Crohns and Colitis Foundation of America Virtual Preceptor Program using the IBD LIVE platform will provide expanded national physician access to this professional education activity.

Endoscopic closure of iatrogenic duodenal perforation during EUS in a patient with unusual anatomy

Michael K. Sanders; Jane Malick; Kenneth E. Fasanella; Andrew R. Watson

Although duodenal perforations occur rarely during upper endoscopy, they are associated with significant morbidity and mortality. Traditionally, surgery is required for managing endoscopic perforations. However, several cases of iatrogenic perforations treated with endoscopic closure techniques have been reported in the literature. The increasing use of EMR and endoscopic submucosal dissection (ESD), as well as the evolution of natural orifice transluminal endoscopic sugery (NOTES) has accelerated the development of new technology with positive clinical outcomes. We describe a case of iatrogenic duodenal perforation during EUS successfully treated with endoscopic closure by using a combination of endoclips and endoloops.

Surgical Morbidity and Mortality Conference using teleconferencing allows for increased faculty participation and moderation from satellite campuses and saves costs.

John L. Falcone; Andrew R. Watson

INTRODUCTION Surgical faculty participation in Morbidity and Mortality Conference (MMC) satisfies criteria for Continuing Medical Education (CME) credit. We hypothesize that using teleconferencing between the main campus to 2 satellite campuses will quantitatively increase faculty attendance and participation as a moderator at surgical MMC. We also want to perform a cost-benefit analysis of teleconferencing. METHODS In this retrospective descriptive study, faculty attendance at MMC at the main campus and 2 satellite campuses was observed from January 1, 2010 through December 31, 2010. Groups were compared with nonparametric statistics, using an α = 0.05. We performed an annual cost-benefit analysis of teleconferencing with consultation of an economist/financial advisor. The explicit and implicit costs of teleconferencing were compared with the opportunity cost-benefit of travel prevention. RESULTS In 2010, there were 45 MMC activities. A total of 236 Continuing Medical Education credit hours were reported, with 186 credit hours at the main campus and 68 credit hours at the satellite campuses. A Mann-Whitney U test showed an increase in the median total attendance (5 per conference) with the addition of the satellite campus attendance (2 per conference) (p < 0.001). There were no differences between the number of moderators at the main campus and the satellite campuses (p > 0.99). Cost benefits per faculty member was
