Endoscopic versus surgical ampullectomy: an algorithm to treat disease of the ampulla of Vater.

OBJECTIVE: The objective of this study was to compare the effectiveness, morbidity, and mortality associated with endoscopic ampullectomy (EA) and surgical ampullectomy (SA). BACKGROUND: The proposed management of benign ampullary lesions includes local resection (EA or SA) and en bloc resection (pancreaticoduodenectomy). Most agree that en bloc resection entails a significant morbidity and mortality. No study has previously compared EA and SA for the treatment of benign ampullary lesions. METHODS: Medical records of patients selected for ampullectomy at Duke University Medical Center from 1991 to 2010 were reviewed. RESULTS: After review, 109 patients were confirmed to have undergone ampullectomy for a suspected benign ampullary lesion. Sixty-eight patients underwent EA, whereas 41 patients underwent SA. Patients in each group were identical in terms of age, sex, race, and comorbid conditions, except that EA had a higher rate of severe obesity (body mass index >35). Endoscopic ampullectomy was found to have a significantly reduced length of stay, lower morbidity, and readmission rates, but it had similar rates of mortality, margin-positive excisions, and reinterventions. CONCLUSIONS: In patients selected for ampullectomy for benign ampullary lesions, EA was found to have equivalent efficacy when compared with SA. Moreover, EA had lower morbidity and identical mortality. These findings suggest that patients would likely benefit from an aggressive endoscopic approach before consideration for surgery.

Repeat imaging in trauma transfers: a retrospective analysis of computed tomography scans repeated upon arrival to a Level I trauma center.

BACKGROUND: The repetition of computed tomography (CT) imaging in caring for injured patients transferred between institutions is common, but it is not well studied. Our objective is to quantify and describe the characteristics associated with repeating chest and abdominal CT images for patients transferred to trauma centers and to determine whether repeat imaging leads to delays in definitive care or disparate outcomes. METHODS: This is a retrospective review of adult, blunt trauma patients transferred to two Level I trauma centers between January 2004 and May 2008 who underwent CT imaging of the chest, abdomen, or both. RESULTS: 60% of patients had at least one study repeated upon arrival to the trauma center. Variables associated with repeat imaging include Injury Severity Scores between 24 and 33 versus <15 (odds radio [OR], 1.6; 95% confidence interval [CI], 1.05-2.4), transfer to University of North Carolina (OR, 1.5; 95% CI, 1.01-2.2), transport by helicopter (OR, 1.6; 95% CI, 1.2-2.2), transfer in any year before 2008 (OR, 2.4; 95% CI, 1.6-3.6 for 2007; OR, 3.4; 95% CI, 2.2-5.3 for 2006; OR, 3.0; 95% CI, 1.8-5.0 for 2005; OR, 2.8; 95% CI, 1.7-4.7 for 2004), and triage alert level higher than the least severe level III (OR, 1.6; 95% CI, 1.01-2.7 for level II; OR, 2.2; 95% CI, 1.2-4.1 for level I). In adjusted models, there was no evidence that repeat imaging neither shortened the total time to definitive care nor altered patient outcomes. CONCLUSIONS: Injured patients often undergo imaging that gets repeated, adding cost and radiation exposure while not significantly altering outcomes. The current policy push to digitize medical records must include provisions for the interoperability and use of imaging software. LEVEL OF EVIDENCE: III, therapeutic study.

Hospital readmission after pancreaticoduodenectomy.

Data exist on the morbidity and mortality of patients undergoing pancreaticoduodenectomy (PD), but there are few reports about hospital readmissions after this procedure. Our aim was to evaluate the number of and reasons for readmission after PD and the factors influencing readmission. We reviewed the initial hospitalization and readmissions for 1643 patients undergoing PD compared patients requiring readmission to patients that did not require readmission. Twenty-six percent of patients were readmitted a total of 678 times after PD. Patients readmitted were younger than those not readmitted (61.8 versus 64.6 years, P < 0.0001). Vessel resection, abscess formation, wound infection, postoperative percutaneous biliary stents, estimated blood loss >1000 ml, and age < or =65 years were independently associated with readmission. The length of stay for all patients decreased over time, from 10.5 days in 1996 to 7 days in 2003. The percentage of patients being readmitted also decreased from 33% in 1996 to 20% (P = 0.004) in 2003. The readmission rate after PD was 26%. Younger age, blood loss, postoperative complications, and vessel resection were independent risk factors for readmission. The early hospital readmission rate has not increased in association with a decreased LOS, supporting the idea that reduction in LOS did not lead to increased readmission rates.

One-year intense nutritional counseling results in histological improvement in patients with non-alcoholic steatohepatitis: a pilot study.

BACKGROUND AND AIM: In individuals with biopsy-proven non-alcoholic steatohepatitis (NASH), short-term weight loss has been shown to improve biochemical abnormalities; however, its effect on liver histology is largely unknown. The aim of the article is to determine if dietary intervention is effective in improving histological features of steatohepatitis in patients with biopsy-proven NASH. METHODS: Twenty-three patients (11M/12F) with BMI >25 kg/m(2) and biopsy-proven NASH received standardized nutritional counseling aimed at reducing insulin resistance (IR) and weight. Blood tests were checked at baseline and every 1-4 months, and liver biopsy was repeated at month 12. IR was assessed by the homeostasis model assessment (HOMA). Liver biopsies were scored according to modified Brunt criteria for NASH. "Histologic response" was defined as a reduction in total NASH score of >/=2 points with at least one point being in the non-steatosis component. RESULTS: Sixteen patients (8M/8F) completed 12 months of dietary intervention, and 15 underwent repeat liver biopsies. At month 12, mean weight decreased from 98.3 to 95.4 kg. Mean waist circumference, visceral fat, fasting glucose, IR, triglycerides, AST, ALT, and histologic score were all reduced but the difference was not significant. Nine patients had a histologic response, six had stable scores, and none had a worsened score. Compared to patients with unchanged histologic scores, patients with improved scores had significantly greater reduction in weight, waist circumference, AST, ALT, steatosis grade, and total NASH score. CONCLUSION: Among patients who successfully completed 1 yr of intense dietary intervention, nine of 15 patients with NASH displayed histologic improvement. This pilot study suggests that dietary intervention can be effective in improving histology in patients with biopsy-proven NASH.

Des-gamma carboxyprothrombin can differentiate hepatocellular carcinoma from nonmalignant chronic liver disease in american patients.

Mortality due to hepatocellular carcinoma (HCC) has not improved over the last 20 years. This is in part due to the poor performance of available tumor markers leading to delays in diagnosis. Des-gamma carboxy-prothrombin (DCP) has been reported to be more sensitive and specific for the diagnosis of HCC in Japanese patients compared with alpha-fetoprotein (AFP). We conducted a cross-sectional case control study to evaluate whether DCP is more sensitive and specific than AFP for differentiating HCC from nonmalignant liver disease in a cohort of American patients from a single referral center. Four groups were studied: G1, normal healthy subjects; G2, patients with noncirrhotic chronic hepatitis; G3, patients with compensated cirrhosis; and G4, patients with histologically proven HCC. A total of 207 subjects were enrolled. Both DCP and AFP levels increased progressively from G1 to G4, but DCP values had less overlap among the groups than AFP. ROC curve indicated that a DCP value of 125 mAU/mL yielded the best sensitivity (89%; 95% CI, 77%-95%) and specificity (95%; 95% CI, 82%-96%) for differentiating patients with HCC from those with cirrhosis and chronic hepatitis. The optimal AFP cutoff value was 11 ng/mL and was inferior to the DCP value of 125 mAU/mL, the area under the ROC curves being 0.928 versus 0.810, respectively (P =.002). In conclusion, DCP was more sensitive and specific than AFP for differentiating HCC from nonmalignant chronic liver disease. Prospective studies to evaluate the role of DCP in early HCC are underway.

NAFLD may be a common underlying liver disease in patients with hepatocellular carcinoma in the United States.

The incidence of hepatocellular carcinoma (HCC) in the United States is increasing, but the clinical characteristics of American patients with HCC have not been well described. The aims of this study were to determine the etiology of liver disease and short-term outcome among HCC patients presenting to a single center in the United States. One hundred five consecutive patients with HCC were studied; mean age was 59 years, 67% were men, and 76% were non-Hispanic white. The most common etiology of liver disease was hepatitis C (51%) and cryptogenic cirrhosis (29%). Half of the patients with cryptogenic cirrhosis had histologic or clinical features associated with nonalcoholic fatty liver disease (NAFLD). Fifty-three (50%) patients had HCC detected during surveillance (group I), whereas the remaining patients had symptomatic tumors (group II). Group I patients had smaller tumors (P =.01), were more likely to be eligible for surgical treatment (P =.005), and had a better median survival compared with patients in group II (P =.001). Patients with cryptogenic cirrhosis were less likely to have undergone HCC surveillance and had larger tumors at diagnosis. In conclusion, hepatitis C and cryptogenic liver disease are the most common etiologies of diseases in our patients with HCC. NAFLD accounted for at least 13% of the cases. Patients who underwent surveillance had smaller tumors and were more likely to be candidates for surgical or local ablative therapies. Because of the increasing incidence of NAFLD, further studies are needed to determine the risk of HCC in patients with NAFLD.
