Same-Day Upper and Lower Inpatient Endoscopy: A Trend for the Future

Performance of same-day upper and lower endoscopy has many potential advantages, as it may reduce costs, shorten hospital stay, and expedite patient care, but its feasibility, efficacy, and potential have not been carefully defined. We report here our experience with a group of 87 patients who underwent same-day upper and lower endoscopy (174 procedures) over a 2-yr period at a tertiary care VA Hospital, compared with an alternate-day upper and lower endoscopy group of 50 patients (100 procedures) over the same time period. Most patients were elderly males. Common indications for endoscopy were occult or overt gastrointestinal bleeding, previous or concomitant history of pertinent pathology (i.e., polyps, ulcers), abdominal pain, diarrhea, or other symptoms, abnormal radiological studies, and iron deficiency anemia. Both groups required similar amounts of intravenous sedation. There were no complications in either group. In both groups, common positive findings were inflammation (i.e., colitis, esophagitis), benign neoplasms, diverticulae, peptic ulcer, and cancer. In both groups, only 2-6% had negative upper and lower endoscopy, whereas either one procedure was negative in 25% and 18% of cases, respectively. We conclude that the practice of same-day inpatient upper and lower endoscopy is feasible, has excellent diagnostic yield, even in the elderly, and carries no increased risks. When indicated, the practice of same-day upper and lower endoscopy should be encouraged.     

"Spontaneous sump syndrome": Successful treatment by duodenoscopic sphincterotomy

"Sump syndrome" is a rare complication of side-to-side choledochoenterostomy operations which develops in the distal, nonfunctioning limb of the common bile duct where lithogenic bile, gastrointestinal contents, and debris accumulate. We report here a patient who developed spontaneous sump syndrome as a result of the formation of choledochoduodenal fistula, and who presented with multiple pyogenic liver abscesses. The patient's symptoms and liver abscesses resolved completely after treatment by endoscopic sphincterotomy and antibiotics. This case demonstrates that sump syndrome may occur spontaneously, that it can be a cause for pyogenic liver abscess formation, and that it may be treated effectively by endoscopic sphincterotomy.     

A prospective study of oesophageal 24-h ambulatory pH monitoring in patients with functional dyspepsia

BACKGROUND: The diagnostic utility of 24-h oesophageal ambulatory pH monitoring in patients with functional dyspepsia has not been well established. AIMS: We performed a prospective study of oesophageal pH monitoring in patients with functional dyspepsia in order to assess whether a positive pH test might predict response to proton pump inhibitor therapy in a subset of functional dyspepsia patients. PATIENTS: Forty Helicobacter pylori-negative functional dyspepsia patients (35 males and 5 females, mean age (+/-S.E.M.) of 54+/-2.4 years) with predominantly unspecified dyspepsia subtype and normal distal oesophageal biopsies. METHODS: All subjects were randomised in a double-blind fashion to either omeprazole 20 mg/day or placebo daily for four weeks after 24-h pH monitoring. RESULTS: Twenty-four-hour pH monitoring was abnormal in 9 of the 21 patients (43%) in the omeprazole group and 5/19 (26%) of the placebo group (p=NS). Patients who reported symptomatic improvement on the Gastrointestinal Symptom Rating Scale were no more likely to have abnormal scores on pH monitoring than patients who did not have symptomatic response. CONCLUSIONS: Although approximately one-third of functional dyspepsia patients will have abnormal profiles on 24-h ambulatory oesophageal pH monitoring, an abnormal score does not appear to predict response to proton pump inhibitor therapy in patients with unspecified functional dyspepsia.

Gene expression changes associated with Barrett's esophagus and Barrett's-associated adenocarcinoma cell lines after acid or bile salt exposure

Background  

Esophageal reflux and Barrett's esophagus represent two major risk factors for the development of esophageal adenocarcinoma. Previous studies have shown that brief exposure of the Barrett's-associated adenocarcinoma cell line, SEG-1, or primary cultures of Barrett's esophageal tissues to acid or bile results in changes consistent with cell proliferation. In this study, we determined whether similar exposure to acid or bile salts results in gene expression changes that provide insights into malignant transformation.     

Communicating with patients with inflammatory bowel disease

Ulcerative colitis and Crohn's disease, the two main forms of inflammatory bowel disease (IBD), are chronic illnesses that affect hundreds of thousands of Americans. Patients with IBD suffer chronically from diarrhea, abdominal pain, gastrointestinal bleeding, malabsorption, and weight loss requiring continuous medical and surgical attention. Despite recent advances in therapy, IBD follows a course of exacerbations and remissions with approximately 25-50% of patients relapsing annually. Hence, these diseases are readily encountered in primary care and gastroenterology clinics. Though medical and surgical treatment options have improved significantly, little has been written about the psychosocial aspects of IBD. Currently, there is a paucity of data concerning effective communication methods enabling physicians to develop stronger rapport with patients suffering from IBD, the care of whom requires a multidisciplinary approach involving primary care physicians, gastroenterologists, and colorectal surgeons. Because IBD has a high morbidity, it is worthwhile to further investigate those social factors that will improve patients' quality of life. In this paper, we summarize some of the common problems that emerge when taking care of patients with IBD and provide initial guidelines based on the world literature regarding the management and education of patients with IBD. Both primary care physicians and specialists (gastroenterologists, colorectal surgeons) need to be aware of the questions and concerns of IBD patients and to be capable of dispensing the information in a clear and concise manner. Using the case scenario format, we review the most common aspects of communication for health care professionals taking care of IBD patients and suggest ways to establish and maintain long-term doctor-patient relationships. The two most significant interventions that dramatically improve quality of life and patient-physician relationships are proper patient education and appropriate treatment of concurrent depression and anxiety. We hope that our review will form a framework by which different members of the medical team learn their roles in the complex management decisions affecting IBD patients.     

Prevalence of Barrett's esophagus in asymptomatic individuals

BACKGROUND & AIMS: The incidence of esophageal adenocarcinoma in the western world has been linked to chronic heartburn, regurgitation, and the development of the premalignant epithelium of Barrett's esophagus (BE). However, up to 40% of esophageal adenocarcinomas occur in patients without prior reflux symptoms. We prospectively screened for the presence of BE in asymptomatic subjects older than 50 years of age undergoing screening sigmoidoscopy for colorectal cancer. METHODS: Subjects undergoing sigmoidoscopy for colorectal cancer (CRC) screening were invited to undergo upper endoscopy. Exclusion criteria included symptoms of gastroesophageal reflux disease (GERD) more than once a month, use of medications for GERD, or previous endoscopy. BE was classified as long-segment BE (LSBE), short-segment BE (SSBE), and microscopic specialized intestinal metaplasia of the esophagogastric junction (SIM-EGJ). RESULTS: Of 408 potential study candidates, 110 subjects were screened; 9 were women. The mean (+/-SD) age was 61 +/- 9.3 (range, 50-80) years, most of them (73%) Caucasian. Intestinal metaplasia (IM) extending above the EGJ was detected in 27 (25%) subjects; 8 (7%) had LSBE, and 19 (17%) had SSBE. Patients with BE were no more likely to be obese, consumers of tobacco or alcohol, report a family history of GERD, show association with toxic exposure, or use antacids more than once a month, compared with those without BE. CONCLUSIONS: BE was detected in 25% of asymptomatic male veterans older than 50 years of age undergoing screening sigmoidoscopy for CRC.
