Prehabilitation and heart failure: perspective in primary outcomes, a randomized controlled trial.

OBJECTIVE: Prehabilitation, intended as a multidisciplinary approach where physical training is combined with educational and counselling training, in cardiology could optimizing care, and has been shown to be able to reduce morbidity and mortality in several diseases. The present study aims to assess the effectiveness of a prehabilitation program in elderly patients (over 65) with chronic heart failure and to evaluate functional and quality indices of life. PATIENTS AND METHODS: This is randomized, single blind controlled trial. Fourteen older adult patients diagnosed with chronic heart failure were enrolled. Patients were randomly assigned into the study or the control group. Patients in the study group underwent physical training organized into 10 twice-weekly meetings, nutritional and lifestyle counseling. RESULTS: In the Study Group, the quality of life improved significantly (EQoL-5D), and between the two groups there is a statistically significant difference in the motor dimension of SF-36. CONCLUSIONS: Because of our preliminary results, prehabilitation program should be included among the management strategies of in elderly patients with chronic heart failure to better manage their disease and to improve their Quality of Life.

Polypharmacy is a determinant of hospitalization in Parkinson's disease.

OBJECTIVE: Patients with Parkinson's disease (PD) are at a higher risk of hospitalization and recurrent hospitalizations, with consequent complications. Polypharmacy is associated with several adverse outcomes, including hospitalization, increased length of hospital stay, and mortality. The aim of this study was to evaluate among patients with PD the association between the number of medications and incident hospitalizations. PATIENTS AND METHODS: We analysed the data of 165 patients with Parkinson's disease attending a geriatric Day Hospital who were enrolled in a cohort study and followed for a median of two years. RESULTS: Over the follow-up, 46 participants (46%) were hospitalized at least one time; multiple admissions were observed in 12 subjects (7%). The median number of agents was 5 (4-7). In Cox regression, the number of drugs was associated with increased hospitalization rates (HR=1.23; 95% CI=1.06-1.43), also after excluding non-neurological medications (HR=1.18; 95% CI=1.01-1.38). Using Poisson regression, polypharmacy (i.e., use of >5 drugs) predicted the number of repeated hospitalizations (IRR=2.62; 95% CI=1.28-5.36; p=.008). CONCLUSIONS: Among patients with PD, the number of daily medications is associated with increased risk of hospitalization; an increasing number of drugs is associated with increasing number of hospitalizations.

Effects of aging and life-long moderate calorie restriction on IL-15 signaling in the rat white adipose tissue.

OBJECTIVE: Phosphorylation of insulin receptor substrate (IRS) 1 by tumor necrosis factor alpha (TNF-α) has been implicated as a factor contributing to insulin resistance. Administration of IL-15 reduces adipose tissue deposition in young rats and stimulates secretion of adiponectin, an insulin sensitizing hormone that inhibits the production and activity of TNF-α. We aimed at investigating the effects of age life-long moderate calorie restriction (CR) on IL-15 and TNF-α signaling in rat white adipose tissue (WAT). MATERIALS AND METHODS: Thirty-six 8-month-old, 18-month-old, and 29-month-old male Fischer344´Brown Norway F1 rats (6 per group) were either fed ad libitum (AL) or calorie restricted by 40%. The serum levels of IL-15 and IL-15 receptor α-chain (IL-15Rα) were increased by CR controls regardless of age. An opposite pattern was detected in WAT. In addition, CR reduced gene expression of TNF-α and cytosolic IRS1 serine phosphorylation in WAT, independently from age. RESULTS: IL-15 signaling in WAT is increased over the course of aging in AL rats compared with CR rodents. Protein levels of IL-15Rα are greater in WAT of AL than in CR rats independently from age. This adaptation was paralleled by increased IRS1 phosphorylation through TNF-α-mediated insulin resistance. Adiponectin decreased at old age in AL rats, while no changes were evident in CR rats across age groups. CONCLUSIONS: IL-15 signaling could therefore represent a potential target for interventions to counteract metabolic alterations and the deterioration of body composition during aging.

Use of ACE-inhibitors and Quality of Life in an Older Population.

BACKGROUND: Improved ability to treat chronic diseases have increased the interest in measuring health-related quality of life (HRQoL) in older adults. Hypertension and heart failure have been associated with decreased HRQoL. HYPOTHESIS: The aim of this study was to assess the association between health-related quality of life and use of angiotensin converting enzyme inhibitors in unselected community-dwelling elderly. METHODS: We analyzed data of all 387 subjects aged 75+ living in a rural Italian town, without exclusion criteria. HRQoL was assessed using the Health Utility Index Mark 3, which allows formal cost-effectiveness calculations. The association of the HRQoL score with use of ACE-I was analyzed by multivariable linear and logistic regression. RESULTS: The median HUI3 score was 0.31, and 186 participants (48%) reported a score above the median value. Use of ACE-I was reported by 34 (9%) participants, and confirmed by general practitioners. Use of these agents was associated with significantly better HRQoL (B=.16, 95% CI=.02 - .30; P=.025). Also, use of ACE-I was associated with increased probability of better HRQoL in logistic regression (OR=2.83; 95% CI=1.03 - 7.78; P=.044) after adjusting. No associations were found between the HRQoL score and use of calcium antagonists or beta-blockers. CONCLUSIONS: Use of ACE-I, but not of other antihypertensives, is associated with better HRQoL among community-dwelling older adults. ACE-inhibitors might therefore present with the best cost-effectiveness ratio for the treatment of older populations.

Inflammation as a mediator of the association between osteoporosis and hearing loss in older subjects: a population-based study.

OBJECTIVE: Due to the aging of populations, the prevalence of hearing loss and osteoporosis is increasing. Previous studies have found an association between these conditions. Nevertheless, the pathophysiologic pathway of such an association has not yet been established. The present study aimed at evaluating the association, if any, of hearing loss with osteoporosis in an older unselected population, and whether this association varied according to inflammatory status. PATIENTS AND METHODS: We assessed the association of osteoporosis with a self-reported hearing loss in all 310 subjects aged 75+ living in Tuscania (Italy), without exclusion criteria. Bone density was assessed by calcaneal quantitative ultrasound; osteoporosis was defined as a T-score ≤ -2.5 Standard Deviation. RESULTS: Hearing loss was associated with osteoporosis (OR = 1.84, 95% CI = 1.03-3.28; p = 0.40) in multivariable logistic regression analysis, after adjusting for potential confounders. Analysis of the interaction term indicated that this association varied according to the erythrocyte sedimentation rate, ERS (p = 0.030), and high-sensitivity C reactive protein, hs-CRP (p = 0.017) but not sex (p = 0.832). Of notice, this association was significant only for higher levels of inflammatory parameters (OR = 2.82; 95% CI = 1.15-6.90; p = 0.023 for the higher ERS tertile; and OR = 3.81; 95% CI = 1.36-10.63; p = 0.011 for the higher hs-CRP tertile vs. lower tertiles). CONCLUSIONS: Hearing loss is associated with osteoporosis in community dwelling elderly. Such an association seems to depend upon higher inflammation levels.

Paracetamol-codeine compared to ketorolac for pain control in the Emergency Department.

OBJECTIVE: Paracetamol /codeine has shown a strong analgesic activity in several studies conducted among different kind of subjects, including those with trauma. Nevertheless, its efficacy in patients accessing the Emergency Department (ED) for different kind of pain has never been tested. PATIENTS AND METHODS: This is a cross-sectional, observational, prospective, cohort study. Inclusion criteria were patients > 18 year old presenting to the ED for localized traumatic or inflammatory pain involving only extremities. Numeric scale (NRS) was recorded thirty minutes and two hours after the administration of the analgesic therapy, consisting of 15 mg of ketorolac or 1000 mg/60 mg of paracetamol/ codeine, both orally. RESULTS: Two-hundred patients were consecutively enrolled; 87 were treated with paracetamol/codeine and 113 with ketorolac. The combination paracetamol/codeine resulted to be not inferior to ketorolac in non-traumatic pain group and trauma group (p = 0.635 and p = 0.482, respectively). Compared to ketorolac, the combination paracetamol/codeine exerted a significantly higher analgesic activity in patients with fractures and muscular pain (p = 0.044) and was more effective in acute pain (p = 0.002), with a significant effect two hours after the administration (p = 0.029). CONCLUSIONS: Paracetamol/codeine is equivalent to ketorolac in non-traumatic pain and post-traumatic pain, but is superior in acute pain and in patients with fractures and muscular pain. Those results play in favor of the use of the combination paracetamol/codeine in patients accessing the ED for non-traumatic or traumatic pain of the extremities.

Management of acute dyarrhea: current and future trends.

Acute diarrhea is a very common symptom, which may recognize different causes and is basically the expression of an altered homeostasis of the bowel, which overcame current classifications. When approaching patients with acute diarrhea, we should firstly check body temperature and vital parameters and secondly provide a general medical examination mainly focused on the abdomen, in order to exclude surgical causes of diarrhea, such as acute appendicitis, diverticulitis, intestinal occlusion and others. Another important aspect is the assessment of the level of hydration in order to provide the right amount of fluids. There is no current indication for the administration of loperamide in infectious diarrhea, but there is a strong rationale for new class of drugs, which may be defined as "mucous regenerators", such as gelatin tannate. Further studies are needed on this matter in order to test the effect of gelatin tannate in adult patients with acute diarrhea.

Safety and efficacy of the combination acetaminophen-codeine in the treatment of pain of different origin.

BACKGROUND: Pain is the most common reason people see doctors in developed Countries and a very common cause of access in Emergency Department (ED). The combination acetaminophen/codeine represents the standard medication in the second step of the WHO analgesic scale and codeine is one of the most commonly used opioid analgesic for a variety of pain conditions. However, many aspects related to safety and efficacy are still undefined. AIM: To summarize and review the results of the most relevant studies on the efficacy and safety profile of acetaminophen/codeine combination in the treatment of pain of different origin. MATERIALS AND METHODS: We performed a literature search to identify and evaluate all relevant english-language randomized controlled trials (RCTs), meta-analyses and reviews about the codeine plus paracetamol combination in the treatment of pain from any source. RESULTS: Acetaminophen/codeine combination is effective in the treatment of moderate to severe pain in all setting analyzed in this study, which include headache, postoperative, osteoarticular and post-traumatic. The best results in terms of safety and efficacy have been obtained in postoperative pain. Efficacy of acetaminophen/codeine combination is not inferior to NSAIDs. CONCLUSIONS: Acetaminophen/codeine combination is effective in the treatment of pain, through a synergistic action of the two molecules, and is not inferior to NSAIDs. Side effects of acetaminophen/codeine are usually minor, differently from NSAIDs, which may induce some potentially life threatening conditions.

Assessment of baseline characteristics and risk factors among Emergency Department patients presenting with recent onset atrial fibrillation: a retrospective cohort study.

BACKGROUND: The Cardioversion of Atrial Fibrillation in Emergency (CAFE) study was an observational, retrospective, multicenter study focusing on patients with recent onset atrial fibrillation (AF) seen in six different Emergency Departments (ED) of Rome, Italy. AIM: The aim of this study was to present the baseline characteristics and risk factors of the patients enrolled to the CAFE study. MATERIALS AND METHODS: We retrospectively reviewed 3085 eligible patients diagnosed with recent onset AF in any of the EDs between January 2008 and December 2009. Inclusion criteria required documented ICD-9 primary discharge/admission diagnosis of AF in the ED and stable hemodynamic conditions at presentation (systolic blood pressure > 90 mmHg). Exclusion criteria were permanent AF or an ongoing acute coronary syndrome. RESULTS: Median age was 71 years (interquartile ranges, 62-78 years) and 50.8% were men. Palpitations was the most common symptom at ED presentation and was present in 73.5% of the study subjects. Hypertension was the most prevalent comorbidity, affecting 59.3% of the patients evaluated, and the presence of previous episode(s) of AF was also common (52.3%). Regarding home treatment, the drugs most prescribed were antiplatelets (31.2%) and diuretics (25.2%). A CHADS2 score of 0 was found in 814 patients (26.4%), while a CHADS2 score of 1 was reported in 1114 patients (36.1%). Finally, a CHADS2 score ≥ 2 was reported in 1157 patients (37.5%). CONCLUSIONS: The present study represents an important snapshot of demographics, comorbidities, risk factors and anticoagulation management about patients with recent onset AF. Disparities were noted in anticoagulation management, suggesting that this is still a main problem among patients with AF.

Recurrent use of the Emergency Department in patients with anxiety disorder.

OBJECTIVE: Panic disorder is characterized by the spontaneous and unexpected occurrence of panic attacks. During panic attacks, patients (pts) refer to the Emergency Department (ED). The diagnostic work-up for any panic attack is expensive since symptoms at presentation mimic other diseases such acute coronary syndrome or neurological emergencies. The aim of the present study was to describe a 10 years cohort of pts diagnosed with panic disorder in the ED in terms of ED visit recurrence. METHODS: Case-control study, in a tertiary care, involving pts presenting to the ED and diagnosed with panic attack according to the International Classification of Diseases 9nt Revision (ICD-9). From January 2001 to Dec 2009 were extracted from the electronic clinical database 469 pts and were divided into "recurrent ED visit" (multiple ED access for panic attack) (N=361) and "no recurrent ED visit" (only one ED access for panic attack in 9 years) (N=108). RESULTS: At univariate analysis cases and controls differed for male prevalence (p < 0.01), neurological symptoms at presentation (p = 0.02) and history of other psychiatry disorder (p < 0.01). In multivariate analysis independent predictors were male gender, age under 40 year old, palpitations at presentations, 1 or more cardiovascular risk factors and previous other psychiatry conditions. CONCLUSIONS: Male under 40 years old with palpitations or cardiovascular risk and other psychiatric diseases, have a higher recurrence of panic attacks. General psychiatric evaluation and treatment with benzodiazepine in ED is not useful to prevent recurrences. Identifying those patients at high risk of panic attack and ED visit recurrence might be useful to establish ad-hoc interventions, improve patients' morbidity and save precious resources.

13C-Urea breath test for the diagnosis of Helicobacter pylori infection.

Helicobacter pylori (H. pylori) is a Gram-negative bacterium able to colonize the gastric mucosa as well as gastric metaplastic areas of the duodenum, producing inflammation. The clinical outcome depends on sophisticated interactions between bacterial factors, such as the expression of determinants of virulence and pathogenicity, and host characteristics. The severity of inflammation, may then vary among different subjects, leading to the occurrence of different gastroduodenal diseases, ranging from chronic gastritis to gastric cancer and MALT-lymphoma, to some defined extragastric manifestations. Many diagnostic tests are available for the detection of H. pylori infection including noninvasive methods, such as serology, (13)C-urea breath test (UBT), and fecal antigen tests and invasive techniques, including a combined use of endoscopic biopsy-based methods, such as rapid urease testing, histology, culture, and molecular methods. UBT is a highly sensitive and specific and allows to diagnose the presence or absence of infection of H. pylori, through the oral administration of a solution containing urea labelled with the non-radioactive natural carbon 13. This review article analyzes microbiological and clinical features of H. pylori as well as the different diagnostic tests able to detect this bacterium with a special focus on UBT.

Needs and challenges of daily life for people with Down syndrome residing in the city of Rome, Italy.

BACKGROUND: Population-based surveys on the quality of life of people with Down syndrome (DS) are difficult to perform because of ethical and legal policies regarding privacy and confidential information, but they are essential for service planning. Little is known about the sample size and variability of quality of life of people with DS living in the city of Rome, which has a population of 2.7 million inhabitants. The aim of the present study is to explore the needs and challenges in health, social integration and daily life, of people with DS living in Rome. METHODOLOGY: A cross-sectional, census-based survey was conducted in 2006. All family doctors (3016 in total) of the National Health Service were involved by the Statistical Bureau of the Municipality of Rome. As per the census, every resident citizen is registered with a family doctor and every person with disabilities is coded. Associations for Down Syndrome encouraged their members to participate in the research. Questionnaires were completed by families of people with DS, in accordance with privacy laws. FINDINGS: An initial survey, conducted via a letter and a telephone contact with family doctors, identified 884 people with DS residing in the city of Rome. Data on the medical and social conditions of 518 people with DS, ranging in age from 0 to 64 years, were collected. Some 88% of these were living with their original family; 82.1% had one or more siblings, and 19.5% had lost one or both parents. A full 100% of children with DS were enrolled in the public school system. This ensures that they are fully occupied and entirely integrated in society. After secondary school there is a lack of opportunities. Thus, only 10% of adults were working with a regular contract. A mere 42.2% of people with DS aged 25-30 were involved in some form of regular activity (although not always on a daily basis). After the age of 30, the percentage of people demonstrating decline in function increased sharply, while disability-related support decreased. In other words, as people with DS age, daily life evolves increasingly around the home, with only occasional outdoor activities. CONCLUSION: The health, employment and social needs of the majority of people with DS in the city of Rome are not being met. The findings of this study underscore the urgent need for more comprehensive inclusion in society of adults with DS and for the provision of support services to create an enabling environment for inclusion. Because of the variability of performance among individuals with DS, there is a need to create more case-specific options in terms of work, living arrangements, social networking and medical services. Schooling and social inclusion in childhood alone do not guarantee a satisfactory quality of life in adulthood. It is argued herewith that policy of inclusion and support should extend over the entire lifetime of people with DS.

Increased lung expansion alters lung growth but not alveolar epithelial cell differentiation in newborn lambs.

Although increased lung expansion markedly alters lung growth and epithelial cell differentiation during fetal life, the effect of increasing lung expansion after birth is unknown. We hypothesized that increased basal lung expansion, caused by ventilating newborn lambs with a positive end-expiratory pressure (PEEP), would stimulate lung growth and alter alveolar epithelial cell (AEC) proportions and decrease surfactant protein mRNA levels. Two groups of lambs were sedated and ventilated with either 0 cmH(2)O PEEP (controls, n = 5) or 10 cmH(2)O PEEP (n = 5) for 48 h beginning at 15 +/- 1 days after normal term birth. A further group of nonventilated 2-wk-old lambs was used for comparison. We determined wet and dry lung weights, DNA and protein content, a labeling index for proliferating cells, surfactant protein mRNA expression, and proportions of AECs using electron microscopy. Although ventilating lambs for 48 h with 10 cmH(2)O PEEP did not affect total lung DNA or protein, it significantly increased the proportion of proliferating cells in the lung when compared with nonventilated 2-wk-old controls and lambs ventilated with 0 cmH(2)O PEEP (control: 2.6 +/- 0.5%; 0 PEEP: 1.9 +/- 0.3%; 10 PEEP: 3.5 +/- 0.3%). In contrast, no differences were observed in AEC proportions or surfactant protein mRNA levels between either of the ventilated groups. This study demonstrates that increases in end-expiratory lung volumes, induced by the application of PEEP, lead to increased lung growth in mechanically ventilated 2-wk-old lambs but do not alter the proportions of AECs.

High accuracy and cost-effectiveness of a biopsy-avoiding endoscopic approach in diagnosing coeliac disease.

BACKGROUND: The 'immersion' technique during upper endoscopy allows the visualization of duodenal villi and the detection of total villous atrophy. AIM: To evaluate the accuracy of the immersion technique in detecting total villous atrophy in suspected coeliac patients. The accuracy in diagnosing coeliac disease and the potential cost-sparing of a biopsy-avoiding approach, based on selection of individuals with coeliac disease-related antibodies and on endoscopic detection of absence of villi, were also analysed. METHODS: The immersion technique was performed in 79 patients with positive antibodies and in 105 controls. Duodenal villi were evaluated as present or absent. As reference, results were compared with histology. Diagnostic approaches, including endoscopy with or without biopsy, were designed to investigate patients with coeliac disease-related antibodies and total villous atrophy. A cost-minimization analysis was performed. RESULTS: All patients with positive antibodies had coeliac disease. The sensitivity, specificity, positive and negative predictive values of endoscopy to detect total villous atrophy was always 100%. The sensitivity, specificity, positive and negative predictive values of biopsy-avoiding or biopsy-including strategies in diagnosing coeliac disease when villi were absent was always 100%. The biopsy-avoiding strategy was cost-sparing. CONCLUSIONS: Upper endoscopy is highly accurate in detecting total villous atrophy coeliac patients. A biopsy-avoiding approach is both accurate and cost-sparing to diagnose coeliac disease in subjects with marked duodenal villous atrophy.

A prospective, randomized multicenter trial comparing DoubleLayer and polyethylene stents for malignant distal common bile duct strictures.

BACKGROUND AND STUDY AIMS: Endoscopic biliary stenting is an established treatment for malignant obstructive jaundice. Stent clogging continues to be a major problem with plastic stents. The aim of this study was to carry out a prospective comparison of two stents with different materials and shapes: the Olympus DoubleLayer stent (DLS; perfluoro alkoxy, without sideholes) and the standard polyethylene (PE) stent (with sideholes). PATIENTS AND METHODS: A total of 120 patients (70 women; mean age 71, range 36 - 91) with jaundice due to malignant strictures of the middle to distal third of the common bile duct were randomly assigned to receive either DLS (n = 60) or PE (n = 60) biliary stents. Patients with cholangitis, hemobilia, previous biliary drainage, hilar stricture, or ampullary cancer were excluded. RESULTS: In all, 28 DLS patients (47 %) and 17 PE stent patients (29 %) died without clinical evidence of stent occlusion after a mean of 114 and 105 days, respectively ( P < 0.05). Twenty-six DLS patients (43 %) and 38 PE stent patients (63 %) had symptoms of stent clogging after a mean of 144 and 99 days, respectively ( P < 0.05). Stent dysfunction (stent orifice impacted on the bile duct or duodenal wall, stent migration) was recorded in six DLS patients (10 %) and five PE patients (8 %) (n. s.). Kaplan-Meier analysis of DLS and PE stent clogging-free survival showed a significantly longer patency period with the DLS stents (P = 0.0005). CONCLUSIONS: These results show that DoubleLayer stents have a longer patency period than PE stents. Patients who received PE stents had a higher risk of stent occlusion (relative risk 3.05; 95 % CI, 1.57 - 5.89) before death than DLS patients.

Endoscopic palliation of unresectable malignant oesophageal strictures with self-expanding metal stents: comparing Ultraflex and Esophacoil stents.

BACKGROUND: Two types of self-expanding metal stents to palliate dysphagia in patients with unresectable malignant oesophageal strictures have been compared. METHODS: From February 1996 to October 2000, 50 metal stents (23 covered Ultraflex and 27 Esophacoil) were placed in 50 patients (40 males, mean age: 67+/-12 years, range: 33-100, mean dysphagia score: 3.18+/-0.66) with unresectable malignant oesophageal strictures. Patients were followed until death. A retrospective review has been made of a prospectively collected database. RESULTS: The two groups were comparable as far as concerns degree of dysphagia, location and stricture length. Stent placement was successful in all cases. Covered Ultraflex stent was placed in 2 patients with oesophagobronchial fistula. No procedure-related deaths were seen. Early severe complications occurred in 2 patients (perforation in 1 and tumour bleeding in 1, in the Esophacoil group). Nine patients and 1 patient complained of pain following Esophacoil and Ultraflex stent placement, respectively. Late complications were asymptomatic rupture of distal Esophacoil rings in 2 patients, symptomatic Ultraflex stent migration in 2 and tumour overgrowth in 3 (Esophacoil 1, Ultraflex 2). Mean dysphagia score at 4 weeks after stent placement was 1.9+/-0.77. Mean survival was 177+/-109 days (range: 35-603 days). There were no significant differences in technical success, dysphagia palliation, complications (except chest pain) and survival using the two types of stent. CONCLUSIONS: Self-expanding metal stents are safe with high technical success and achieve satisfactory long-term palliation for dysphagia. The covered Ultraflex and Esophacoil stents are equally effective.

Long-term follow-up of patients after endoscopic sphincterotomy for choledocholithiasis, and risk factors for recurrence.

BACKGROUND AND STUDY AIMS: There have been growing concerns about the long-term sequelae of endoscopic sphincterotomy (ES). The aims of the study were to evaluate the long-term clinical outcome of ES for choledocholithiasis and to identify the predictors of recurrence. PATIENTS AND METHODS: A total of 529 patients (233 men, 296 women; mean age 63, range 9 - 88) who underwent successful ES for choledocholithiasis were evaluated. Follow-up data were obtained retrospectively. Statistical analyses were carried out for 334 patients who had a follow-up of at least 5 years or had recurrence. RESULTS: Immediate complications occurred in 37 patients (7 %). Follow-up data were available in 458 patients (86.6 %), of whom 280 (61.1 %) were asymptomatic, 127 (27.7 %) died from unrelated causes without recurrence, and 51 (11.1 %) had biliary symptoms and/or choledocholithiasis recurrence. Most recurrences (65 %) occurred more than 2 years following ES and were observed on multiple occasions in 13 patients (2.8 %). A bile duct diameter of 22 mm or greater was found to predict recurrence. Of 190 patients with an intact gallbladder, 11 (5.8 %) developed acute cholecystitis necessitating emergency cholecystectomy; all of these had previously documented gallstones. CONCLUSIONS: Endoscopic sphincterotomy for choledocholithiasis is found to be safe at long-term follow-up. A dilated bile duct (> or = 22 mm) is a marker for patients at increased risk of recurrence of symptoms and/or choledocholithiasis.
