摘要:
Gallstones are a common cause of acute pancreatitis. This article reviews acute biliary pancreatitis and includes natural history, noting the serious nature of some cases; pathogenesis, identifying transient obstruction as the primary pathogenetic event; diagnosis, including biochemical parameters and imaging; assessment of severity, underlining the importance of early prognostic signs, organ failure, and local complications; and management. Management is reviewed in detail, giving a historical perspective to the role of surgery, highlighting the role of endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy and paying particular attention to the four prospective randomized clinical trials in suggesting which patients are most likely to benefit from early endoscopic evaluation and therapy. Also discussed are additional clinical situations related to biliary pancreatitis in which endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy play a role. Finally, a suggested endoscopic approach to acute biliary pancreatitis is presented along with an algorithm incorporating severity stratification, principles of endoscopic intervention, and concepts of sterile and infected pancreatic necrosis.

摘要:
Screening sigmoidoscopy is associated with a 45% to 80% reduction in colorectal cancer mortality. Although less than 50% of eligible Americans have been screened with flexible sigmoidoscopy (FS), the use of this procedure is rising rapidly. By the year 2000, as many as 10 million screening FS per year could be performed. To accommodate the increased demand, many medical centers have trained paramedical personnel (i.e. physician assistants, nurses, and gastroenterology technicians) to perform FS. However, as a result of the paucity of research about this practice, only physicians receive a professional fee for performing screening FS. Many state Boards of Nursing explicitly prohibit registered nurses (RNs) from performing this procedure. This review outlines research about the effectiveness of paramedical endoscopists, medico-legal and reimbursement issues, and outlines a training program in FS for paramedical personnel.

摘要:
Specialty practice in general, and gastroenterology in particular, is undergoing significant transformation as we head into the new millennium. Gastroenterologists will need to adapt to the continued evolution and consolidation of managed care. Among other issues, gastroenterologists will need strategies for dealing with pricing pressures, changing technology, increased consumerism, a perceived specialist oversupply, and a rapidly aging population. These and other developments will drive a myriad of physician responses in an effort to confront changing practice realities.

摘要:
Treatment of achalasia includes pneumatic dilation (PD) and surgical myotomy (SM). Success rates range from 32% to 98% and are mostly based on symptomatic response. Our aims were to determine the long-term outcome of patients treated for achalasia and the adequacy of long-term follow-up.Patients treated with PD or SM between 1986 and 1990 were contacted by telephone after a minimum of 4 years after treatment, and asked about symptoms and need for retreatment since their discharge from our institution. Symptomatic response was classified as excellent/good or fair/poor using the Vantrappen score. Treatment was deemed a failure if patients were symptomatic on callback, needed retreatment, technical problems occurred during PD, or perforation occurred.Forty-seven PD patients and 15 SM patients were studied. There were no significant differences in clinical parameters between groups. Median time to callback was 82 and 73 months, respectively. Failure rates were high, respectively 74% and 67%. Importantly, 38% of PD and 33% of SM patients failed to seek help despite symptom recurrence.Achalasia treatment failures are higher than anticipated. This may be because of the lack of routine follow-up as well as patients' failure to seek help when symptoms recur. Achalasia patients need closer follow-up and may benefit from early intervention based on objective tests rather than symptoms alone.

摘要:
Intravenous erythromycin is a potent gastric prokinetic with demonstrated efficacy in the acute therapy of gastroparesis; long-term oral therapy has been limited by tolerance and modest efficacy. Our aim was to review our experience with prolonged administration of intravenous erythromycin in an ambulatory setting as therapy for severe gastroparesis, refractory to usual dietary and oral prokinetic regimens.We conducted a retrospective analysis of patients with gastroparesis treated with intravenous erythromycin for at least 1 month. Information on demographics; origin of gastroparesis; dosage, duration, and route of administration; clinical outcome in the short- and longer-term; and complications were determined.Eleven patients received a total of 14 courses of intravenous erythromycin for a median of 6.5 months (range, 1 to 19 months) at a median dosage of 300 mg/day (range, 150 to 1,000 mg/day). One patient received no benefit, two had complete responses, and all others reported some benefit. Two had dramatic relapse on cessation of therapy and subsequently improved on its resumption. Parenteral nutrition could be discontinued in one of four patients. There were four episodes of line sepsis; two required catheter removal. A nonocclusive thrombus developed at the site of a central line in one patient. Secondary infections or antibiotic resistance were not encountered.Prolonged administration of intravenous erythromycin in an ambulatory setting is feasible, well tolerated, and effective in patients with severe gastroparesis.

摘要:
Cancers of the esophagus, gastroesophageal junction (including the gastric cardia), and stomach represent three separate diseases with marked epidemiologic variations. The Department of Veterans Affairs computerized database records the ethnicity of all hospitalized patients throughout the United States, which provides an opportunity to study the influence of ethnicity on cancer rates in a uniform health-care system.All hospitalized patients, from 1980 through 1995, with a diagnosis of upper gastrointestinal cancer were identified. For each ethnic group and cancer type, hospitalization was expressed as an age-adjusted proportional rate per 10,000 hospitalizations from all causes.Hospitalization with gastric cancer was most frequent among Asians (48.4 per 10,000 hospitalizations) followed by blacks (33.3), Hispanics (28.7), American Indians (20.3), and whites (12.0). Adenocarcinoma of the gastroesophageal junction accounted for 5.9 per 10,000 hospitalizations among Asians, 4.5 among whites, and 4.5 among Hispanics. Gastroesophageal junction cancer was lowest among blacks (2.9) and American Indians (2.4). Finally, squamous cell carcinoma of the esophagus was frequent among blacks, 68.2 per 10,000, followed by Hispanics (36.4) and Asians (27.8), and was low among whites 24.0 and American Indians (21.5). Esophageal cancer rates remained stable in all ethnic groups from 1980 through 1995; gastroesophageal junction cancer rates increased particularly among whites, whereas gastric cancer rates declined in whites and blacks but not in Hispanics.There were significant ethnic differences in the occurrence of gastroesophageal malignancies among US military veterans. Environmental factors may explain some of these differences. Differential rates ofHelicobacter pyloriinfection with resultant gastric atrophy and reduced acid output led to a greater risk for gastric cancer, but a reduced risk for reflux disease and cardiac cancer.
