| 1 | Percutaneous endoscopic gastrostomy:Indications,technique,complications and management显示文摘Percutaneous endoscopic gastrostomy(PEG)is the preferred route of feeding and nutritional support in patients with a functional gastrointestinal system who require long-term enteral nutrition.Besides its wellknown advantages over parenteral nutrition,PEG offers superior access to the gastrointestinal system over surgical methods.Considering that nowadays PEG tube placement is one of the most common endoscopic procedures performed worldwide,knowing its indications and contraindications is of paramount importance in current medicine.PEG tubes are sometimes placed inappropriately in patients unable to tolerate adequate oral intake because of incorrect and unrealistic understanding of their indications and what they can accomplish.Broadly,the two main indications of PEG tube placement are enteral feeding and stomach decompression.On the other hand,distal enteral obstruction,severe uncorrectable coagulopathy and hemodynamic instability constitute the main absolute contraindications for PEG tube placement in hospitalized patients.Although generally considered to be a safe procedure,there is the potential for both minor and major complications.Awareness of these potential complications,as well as understanding routine aftercare of the catheter,can improve the quality of care for patients with a PEG tube.These complications can generally be classified into three major categories:endoscopic technical difficulties,PEG procedure-related complications and late complications associated with PEG tube use and wound care.In this review we describe a variety of minor and major tube-related complications as well as strategies for their management and avoidance.Different methods of percutaneous PEG tube placement into the stomach have been described in the literature with the'pull'technique being the most common method.In the last section of this review,the reader is presented with a brief discussion of these procedures,techniques and related issues.Despite the mentioned PEG tube placement complications,this procedure has gained worldwide popularity as a safe enteral access for nutrition in patients with a functional gastrointestinal system. | Ata A Rahnemai-Azar Amir A Rahnemaiazar Rozhin Naghshizadian Amparo Kurtz Daniel T Farkas | 2014 | World Journal of Gastroenterology2014，20，24： | 38 |
| 2 | Carcinoma in situ in a 7 mm gallbladder polyp: Time to change current practice?显示文摘Detection of polypoid lesions of the gallbladder is increasing in conjunction with better imaging modalities. Accepted management of these lesions depends on their size and symptomatology. Polyps that are symptomatic and/or greater than 10 mm are generally removed, while smaller, asymptomatic polyps simply monitored. Here, a case of carcinoma-in-situ is presented in a 7 mm gallbladder polyp. A 25-year-old woman, who had undergone a routine cholecystectomy, was found to have an incidental 7 mm polyp containing carcinoma in situ. She had few to no risk factors to alert to her condition. There are few reported cases of cancer transformation in gallbladder polyps smaller than 10 mm reported in the literature. The overwhelming consensus, barring significant risk factors for cancer being present, is that such lesions should be monitored until they become symptomatic or develop signs suspicious for malignancy. In our patient's case this could have led to the possibility of missing a neoplastic lesion, which could then have gone on to develop invasive cancer. As gallbladder carcinoma is an aggressive cancer, this may have led to a tragic outcome. | David Kasle Amir A Rahnemai-Azar Shahida Bibi Vinaya Gaduputi Brian F Gilchrist Daniel T Farkas | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，9： | 8 |
| 3 | Laparoscopic vs open partial colectomy in elderly patients:Insights from the American College of Surgeons- National Surgical Quality Improvement Program database显示文摘AIM: To compare the outcomes between the laparoscopic and open approaches for partial colectomy in elderly patients aged 65 years and over using the American College of Surgeons- National Surgical Quality Improvement Program(ACS NSQIP) database. METHODS: The ACS NSQIP database for the years 2005-2011 was queried for all patients 65 years and above who underwent partial colectomy. 1:1 propensity score matching using the nearest- neighbor method was performed to ensure both groups had similar preoperative comorbidities. Outcomes including postoperative complications, length of stay and mortality were compared between the laparoscopic and open groups. χ2 and Fisher's exact test were used for discrete variables and Student's t-test for continuous variables. P < 0.05 was considered significant and odds ratios with 95%CI were reported when applicable. RESULTS: The total number of patients in the ACS NSQIP database of the years 2005-2011 was 1777035. We identified 27604 elderly patients who underwent partial colectomy with complete data sets. 12009(43%) of the cases were done laparoscopically and15595(57%) were done with open. After propensity score matching, there were 11008 patients each in the laparoscopic(LC) and open colectomy(OC) cohorts. The laparoscopic approach had lower post-operative complications(LC 15.2%, OC 23.8%, P < 0.001), shorter length of stay(LC 6.61 d, OC 9.62 d, P < 0.001) and lower mortality(LC 1.6%, OC 2.9%, P < 0.001). CONCLUSION: Even after propensity score matching, elderly patients in the ACS NSQIP database having a laparoscopic partial colectomy had better outcomes than those having open colectomies. In the absence of specific contraindications, elderly patients requiring a partial colectomy should be offered the laparoscopic approach. | Umashankkar Kannan Vemuru Sunil K Reddy Amar N Mukerji Vellore S Parithivel Ajay K Shah Brian F Gilchrist Daniel T Farkas | 2015 | World Journal of Gastroenterology2015，21，45： | 3 |

| 16 | Influence of carbon-based cathodes on biofilm composition and electrochemical performance in soil microbial fuel cells显示文摘Increasing energy demands and environmental pollution concerns press for sustainable and environmentally friendly technologies.Soil microbial fuel cell(SMFC)technology has great potential for carbon-neutral bioenergy generation and self-powered electrochemical bioremediation.In this study,an in-depth assessment on the effect of several carbon-based cathode materials on the electrochemical performance of SMFCs is provided for the first time.An innovative carbon nanofibers electrode doped with Fe(CNFFe)is used as cathode material in membrane-less SMFCs,and the performance of the resulting device is compared with SMFCs implementing either Pt-doped carbon cloth(PtC),carbon cloth,or graphite felt(GF)as the cathode.Electrochemical analyses are integrated with microbial analyses to assess the impact on both electrogenesis and microbial composition of the anodic and cathodic biofilm.The results show that CNFFe and PtC generate very stable performances,with a peak power density(with respect to the cathode geometric area)of 25.5 and 30.4 mW m^(−2),respectively.The best electrochemical performance was obtained with GF,with a peak power density of 87.3 mW m^(−2).Taxonomic profiling of the microbial communities revealed differences between anodic and cathodic communities.The anodes were predominantly enriched with Geobacter and Pseudomonas species,while cathodic communities were dominated by hydrogen-producing and hydrogenotrophic bacteria,indicating H_(2)cycling as a possible electron transfer mechanism.The presence of nitrate-reducing bacteria,combined with the results of cyclic voltammograms,suggests microbial nitrate reduction occurred on GF cathodes.The results of this study can contribute to the development of effective SMFC design strategies for field implementation. | Arpita Nandy Daniel Farkas Belén Pepió-Tárrega Sandra Martinez-Crespiera Eduard Borràs Claudio Avignone-Rossa Mirella Di Lorenzo | 2023 | Environmental Science and Ecotechnology2023，，4： | 0 |
