GOALS: To determine the frequency of gastrointestinal lesions detected by upper endoscopy and colonoscopy in patients who developed iron deficiency anemia after Billroth II surgery. STUDY: The authors reviewed the medical records of 116 consecutive patients with a Billroth II partial gastrectomy and 232 age- and gender-matched controls without gastric surgery who were referred for endoscopy to evaluate iron deficiency anemia over a 5-year period. RESULTS: Clinically important lesions were detected in 22.4% of the patients with gastric surgery and in 59.5% of those with intact stomachs (p < 0.001). In the gastric surgery group, clinically important lesions were found more often in the upper gastrointestinal tract than in the colon (19.0% vs. 3.4%, p < 0.001). In the nonsurgical group, the diagnostic yields of upper endoscopy and colonoscopy were not significantly different (38.4% vs. 32.8%, p = 0.24). Synchronous lesions in the upper and lower gastrointestinal tract were significantly less common in the group of patients with gastric surgery compared with those without gastric surgery (0.0% vs. 11.6%, p < 0.001). Small bowel biopsies and small bowel follow-through did not identify any additional lesions. In the gastric surgery group, multivariate analysis identified abdominal symptoms (OR = 11.2, 95% CI 3.2-39.2, p < 0.001), a positive result on fecal occult blood testing (OR = 6.4, 95% CI 2.0-20.3, p = 0.002), and Billroth II surgery at least 10 years before evaluation (OR = 5.4, 95% CI 1.7-16.7, p = 0.004) as independent predictors of identifying a clinically important lesion by endoscopy. CONCLUSIONS: Upper endoscopy had a significantly higher diagnostic yield than colonoscopy in patients who developed iron deficiency anemia after Billroth II surgery. Prospective studies are necessary to determine the role and cost-effectiveness of colonoscopy in the evaluation of iron deficiency anemia in this patient population

Managed care has strongly discouraged generalists from referring patients to specialists in an effort to reduce the costs of health care. The aim of this study was to compare patient outcomes when generalists work together with gastroenterologists or alone in the management of patients admitted to the hospital with decompensated cirrhosis. Consecutive patients admitted to the hospital with decompensated cirrhosis over a 1-year period were identified. We compared the length of stay, cost of hospitalization, incidence of hospital readmission, and mortality for patients who did and those who did not have a gastroenterology (GI) consultation. A GI consultation was requested for 107 of the 197 patients (54.3%). Patients who had a GI consultation had a significantly shorter length of stay (5.6 +/- 3.5 vs. 10.1 +/- 5.8 days, P <.001) and a lower cost of hospitalization ($6,004 +/- $4,994 vs. $10,006 +/- $6,183, P <.001) than those patients who were managed by generalists alone. The 30-day incidence of readmission (13.3% vs. 27.8%, P =.01) and mortality (7.5% vs. 16.7%, P =.045) were significantly lower in the GI consultation group. During a median follow-up of 618 days (range, 2-970), patients who had a GI consultation during hospitalization had a significantly longer time to hospital readmission (P <.001) and improved survival (P =.02) compared with those who were managed by generalists alone. In conclusion, for patients admitted to the hospital with decompensated cirrhosis, individuals who were managed by generalists in conjunction with gastroenterologists had better outcomes than those who were managed by generalists alone

Meckel's diverticulum, which is the most common congenital anomaly of the gastrointestinal tract, occurs when the vitelline duct persists past the 7th week of gestation. Although complications may occur in 8% to 22% of patients with Meckel's diverticula, adenocarcinoma is very uncommon. We describe a patient with early gastric cancer who was incidentally found to have a superficial adenocarcinoma arising from ectopic gastric mucosa within a Meckel's diverticulum. To the best of our knowledge, synchronous gastric adenocarcinoma in a patient with Meckel's diverticulum has not been previously reported
