| 1 | HIDA scan for functional gallbladder disorder: ensure that you know how the scan was done显示文摘BACKGROUND: Despite the increasing use of fatty meal(FM) as a substitute for cholecystokinin(CCK) in pain reproduction during hepato-imino-diacetic acid(HIDA) scan in functional gallbladder disorder, there are no studies comparing the differences between CCK and FM. The present study was to compare the efficacy of FM in comparison of CCK in FGBD application. METHODS: Patients undergoing HIDA scans from August 2013 to May 2014 were divided into two groups: those undergoing CCK-stimulated HIDA scan versus FM-stimulated HIDA scan. These groups were compared according to demographics and HIDA results.RESULTS: Of 153 patients, 70 received CCK and 83 FM. There was no difference regarding age, gender, gallstones, gallbladder ejection fraction and time to visualization. However, significantly more of the patients receiving CCK than FM experienced pain reproduction(61% vs 30%, P<0.01).CONCLUSIONS: Stimulation of gallbladder contractility with a FM during HIDA is less than half as likely to reproduce biliary symptoms compared to CCK, despite similar ejection fractions and other parameters. It is essential that providers account for this difference when counseling patients regarding cholecystectomy for functional gallbladder disorder. | Naeem Goussous Hadia Maqsood Ethan Spiegler Gopal C Kowdley Steven C Cunningham | 2017 | Hepatobiliary & Pancreatic Diseases International2017，16，2： | 5 |
| 2 | Molecular biology techniques for the surgeon显示文摘New technologies are constantly being introduced into the medical and surgical fields. These technologies come in the form of newer medicines, imaging methods and prognostic tools, among others, and allow clinicians to make more rational and informed decisions on the care of their patients. Many of these technologies utilize advanced techniques which are at the forefront of many research fields and represent a transition of bench advances into the clinical realm. This review will highlight four technologies that are at the forefront in the treatment of oncology patients treated by surgeons on a daily basis. Circulating tumor cells, microarray analysis, proteomic studies and rapid sequencing technologies will be highlighted. These technologies will be reviewed and their potential use in the care o surgical patients will be discussed. | Gopal Kowdley Subramanya Srikantan Kotb Abdelmohsen Myriam Gorospe Javeed Khan | 2012 | World Journal of Surgical Procedures2012，2，2： | 0 |
| 3 | Detecting accidental punctures and lacerations during cholecystectomy in large datasets: Two methods of analysis显示文摘Background: After the Institute of Medicine(IOM) report To Err Is Human highlighted the impact of medical errors, the Agency for Healthcare Research and Quality(AHRQ) developed Patient-Safety Indicators(PSI) to improve quality by identifying potential inpatient safety problems. PSI-15 was created to study accidental punctures and lacerations(APL), but PSI-15 may underestimate APLs in populations of patients. This study compares PSI-15 with a more inclusive approach using a novel composite of secondary diagnostic and procedural codes. Methods: We used Nationwide Inpatient Sample(NIS) data(20 0 0–2012) from AHRQ's Healthcare Cost and Utilization Project(H-CUP). We analyzed PSI-15-positive and-negative cholecystectomies. Cross tabulations identified codes that were significantly more frequent among PSI-15-positive cases; these secondary diagnostic and procedural codes were selected as candidate members of a composite marker(CM) of APL. We chose cholecystectomy patients for study because this is one of the most common general operations, and the large size of NIS allows for meaningful analysis of infrequent occurrences such as APL rates. Results: CM identified 1.13 times more APLs than did PSI-15. Patients with CM-detected APLs were significantly older and had worse mortality, comorbidities, lengths of stay, and charges than those detected with PSI-15. Further comparison of these two approaches revealed that time-series analysis for both APL markers revealed parallel trends, with inflections in 2007, and lowest APL rates in July. Conclusions: Although CM may yield more false positives, it appears more inclusive, identifying more clinically significant APLs, than PSI-15. Both measures presented similar trends over time, arguing against inflation in PSI-15 reporting. While arguably less specific, CM may increase sensitivity for detecting APL events during cholecystectomies. These results may inform the interpretation of other large population studies of APLs following abdominal operations. | Artem Shmelev Anne M Sill Gopal C Kowdley Juan A Sanchez Steven C Cunningham | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，5： | 0 |
| 4 | Energetic etiologies of acute pancreatitis: A report of five cases显示文摘There are several common causes of acute pancreatitis, principally excessive alcohol intake and gallstones, and there are many rare causes. However, cases of pancreatitis still occur in the absence of any recognizable factors, and these cases of idiopathic pancreatitis suggest the presence of unrecognized etiologies. Five cases of acute pancreatitis in four patients came to attention due to a strong temporal association with exposure to nerve stimulators and energy drinks. Given that these cases of pancreatitis were otherwise unexplained, and given that these exposures were not clearly known to be associated with pancreatitis, we performed a search for precedent cases and for mechanistic bases. No clear precedent cases were found in Pub Med and only scant, weak precedent cases were found in public-health databases. However, there was a coherent body of intriguing literature in support of a mechanistic basis for these exposures playing a role in the etiology of pancreatitis. | Artem Shmelev Alain Abdo Sarina Sachdev Urvi Shah Gopal C Kowdley Steven C Cunningham | 2015 | World Journal of Gastrointestinal Pathophysiology2015，6，4： | 0 |
