| 1 | Incidence and risk factors for the development of anemia following gastric bypass surgery显示文摘AIM:To evaluate the incidence and risk factors for the development of anemia after RouxenY gastric bypass (RYGB).METHODS: A retrospective analysis of patients undergoing RYGB from January 2003 to November 2007 was performed. All patients had a preoperative body mass index > 40 kg/m2. A total of 206 patients were evaluated. All patients were given daily supplements of ferrous sulfate tablets for 2 wk following their operation. Hematological and metabolic indices were routinely evaluated following surgery. Patients were followed for a minimum of 86 wk.RESULTS: There were 41 males and 165 females with an average age of 40.8 years. 21 patients (10.2%) developed postoperative anemia and 185 patients (89.8%) did not. Anemia was due to iron deficiency in all cases. The groups had similar demographics, surgical procedure and comorbidities. Menstruation (P = 0.02) and peptic ulcer disease (P = 0.01) were risk factors for the development of postoperative anemia.CONCLUSION: Iron deficiency anemia is frequent. RYGB surgery compounds occult blood loss. Increased ferrous sulfate supplementation may prevent iron depletion in populations at increased risk. | Dimitrios V Avgerinos Omar H Llaguna Matthew Seigerman Amanda J Lefkowitz I Michael Leitman | 2010 | World Journal of Gastroenterology2010，16，15： | 6 |
| 2 | Laparoscopic cholecystectomy for a left-sided gallbladder显示文摘Cholecystectomy is a common procedure.Abnormalities in the anatomy of the biliary system are common but an abnormal location of the gallbladder is much rarer.Despite frequent pre-operative imaging,the aberrant location of the gallbladder is commonly discovered at surgery.This article presents a case of a patient with the gallbladder located to the left of the falciform ligament in the absence of situs inversus totalis that presented with right upper quadrant pain.A laparoscopic cholecystectomy was performed and it was noted that the cystic duct originated from the right side.The presence of a left sided gall bladder is often associated with various biliary,portal venous and other anomalies that might lead to intra-operative injuries.The spectrum of unusual positions and anatomical gallbladder abnormalities is reviewed in order to facilitate elective and emergent cholecystectomy as well as other hepatobiliary procedures.With proper identification of the anatomy,minimally invasive approaches are still considered safe. | Mazen E Iskandar Agnes Radzio Merab Krikhely I Michael Leitman | 2013 | World Journal of Gastroenterology2013，19，35： | 4 |
| 3 | Endoscopic ultrasound and paracentesis in the evaluation of small volume ascites in patients with intra-abdominal malignancies显示文摘The evaluation of ascites in patients with known or suspected malignancy is a critical aspect of preoperative staging.Endoscopic evaluation by ultrasound of low volume ascites and sampling of the ascitic fluid by endoscopic ultrasound guided paracentesis(EUS-P)is both a sensitive and specific modality for the determination of peritoneal implants,which is not only an important prognostic indicator but a crucial factor in determining treatment strategy.It is common practice to utilize EUS for gastrointestinal malignancies such as pancreatic or gastric masses,with the performance of paracentesis during the same procedure for the purpose of imaging the abnormality and possibly performing fine needle aspiration for biopsy of the neoplasm itself.However,given the ability of EUS-P to adequately sample even minimal ascites,detecting much smaller volumes than traditional computed tomography or magnetic resonance imaging,EUS-P may be a useful modality for the standard metastatic workup of any newly diagnosed or suspected malignancy.In this'Field of Vision'commentary,we discuss the role of EUS-P,including the article by Suzuki et al reporting their experience with EUS-P using an automated spring-loaded needle device.We also review the utility of EUS-P for non-gastrointestinal malignancies,such as ovarian cancer,which has a high incidence of malignant ascites. | Marissa M Montgomery I Michael Leitman | 2014 | World Journal of Gastroenterology2014，20，30： | 3 |
| 4 | Delayed assessment and eager adoption of laparoscopic cholecystectomy:Implications for developing surgical technologies显示文摘Despite the prevailing emphasis in the medical literature on establishing evidence,many changes in the practice of surgery have not been achieved using proper evidence-based assessment.This paper examines the adoption of laparoscopic cholecystectomy(LC)into regular use for the treatment of cholecystitis and the process of its acceptance,focusing on the limited role of technology assessment in its appraisal.A review of the published medical literature concerning LC was performed.Approximately 3000 studies of LC have been conducted since 1985,and there have been nearly 8500 publications to date.As LC was adopted enthusiastically into practice,the results of outcome studies generally showed that it compared favorably with the traditional,open cholecystectomy with regard to mortality,complications,and length of hospital stay.However,despite the rapid general agreement on surgical technique,efficacy,and appropriateness,there remained lingering doubts about safety,outcomes,and cost of the procedure that suggested that essential research questions were ignored even as the procedure became standard.Using LC as a case study,there are important lessons to be learned about the need for important guidelines for surgical innovation and the adoption of minimally invasive surgical techniques into current clinical and surgical practice.We highlight one recent example,natural orifice transluminal endoscopic surgery and how necessary it is to properly evaluate this new technology before it is accepted as a safe and effective surgical option. | Alexander C Allori I Michael Leitman Elizabeth Heitman | 2010 | World Journal of Gastroenterology2010，16，33： | 3 |
