| 1 | Trends and outcomes of pancreaticoduodenectomy for periampullary tumors: A 25-year single-center study of 1000 consecutive cases显示文摘AIM To evaluate the evolution, trends in surgical approaches a n d r e c o n s t r u c t i o n t e c h n i q u e s, a n d i m p o r t a n t lessons learned from performing 1000 consecutive pancreaticoduodenectomies(PDs) for periampullary tumors.METHODS This is a retrospective review of the data of all patients who underwent PD for periampullary tumor during the period from January 1993 to April 2017. The data were categorized into three periods, including early period(1993-2002), middle period(2003-2012), and late period(2013-2017).RESULTS The frequency showed PD was increasingly performed after the year 2000. With time, elderly, cirrhotic and obese patients, as well as patients with uncinate process carcinoma and borderline tumor were increasingly selected for PD. The median operative time and postoperative hospital stay decreased significantly over the periods. Hospital mortality declined significantly, from 6.6% to 3.1%. Postoperative complications significantly decreased, from 40% to 27.9%. There was significant decrease in postoperative pancreatic fistula in the second 10 years, from 15% to 12.7%. There was a significant improvement in median survival and overall survival among the periods.CONCLUSION Surgical results of PD significantly improved, with mortality rate nearly reaching 3%. Pancreatic reconstruction following PD is still debatable. The survival rate was also improved but the rate of recurrence is still high, at 36.9%. | ayman el nakeeb waleed askar ehab atef ehab el hanafy ahmad m sultan tarek salah ahmed shehta mohamed el sorogy emad hamdy mohamed el hemly ahmed a el-geidi tharwat kandil mohamed el shobari talaat abd allah amgad fouad mostafa abu zeid ahmed abu el eneen nabil gad el-hak gamal el ebidy omar fathy ahmed sultan mohamed abdel wahab | 2017 | World Journal of Gastroenterology2017，23，38： | 15 |
| 2 | Predictors of long term survival after hepatic resection for hilar cholangiocarcinoma:A retrospective study of 5-year survivors显示文摘AIM:To determine predictors of long term survival after resection of hilar cholangiocarcinoma(HC) by comparing patients surviving > 5 years with those who survived < 5 years.METHODS:This is a retrospective study of patients with pathologically proven HC who underwent surgical resection at the Gastroenterology Surgical Center,Mansoura University,Egypt between January 2002 and April 2013.All data of the patients were collected from the medical records.patients were divided into two groups according to their survival:patients surviving less than 5 years and those who survived > 5 years.RESULTS:There were 34(14%) long term survivors(5 year survivors) among the 243 patients.Fiveyear survivors were younger at diagnosis than those surviving less than 5 years(mean age,50.47 ± 4.45 vs 54.59 ± 4.98,p = 0.001).Gender,clinical presentation,preoperative drainage,preoperative serum bilirubin,albumin and serum glutamic-pyruvic transaminase were similar between the two groups.The level of CA 19-9 was significantly higher in patients surviving < 5 years(395.71 ± 31.43 vs 254.06 ± 42.19,p = 0.0001).Univariate analysis demonstrated nine variables to be significantly associated with survival > 5 year,includingyoung age(p = 0.001),serum CA19-9(p = 0.0001),non-cirrhotic liver(p = 0.02),major hepatic resection(p = 0.001),caudate lobe resection(p = 0.006),well differentiated tumour(p = 0.03),lymph node status(0.008),R0 resection margin(p = 0.0001) and early postoperative liver cell failure(p = 0.02).CONCLUSION:Liver status,resection of caudate lobe,lymph node status,R0 resection and CA19-9 were demonstrated to be independent risk factors for long term survival. | Mohamed Abd El Wahab Ayman El Nakeeb Ehab El Hanafy Ahmad M Sultan Ahmed Elghawalby Waleed Askr Mahmoud Ali Mohamed Abd El Gawad Tarek Salah | 2016 | World Journal of Gastrointestinal Surgery2016，8，6： | 10 |
| 3 | Post-endoscopic retrograde cholangiopancreatography pancreatitis: Risk factors and predictors of severity显示文摘AIM To detect risk factors for post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP) and investigate the predictors of its severity.METHODS This is a prospective cohort study of all patients who underwent ERCP.Pre-ERCP data,intraoperative data,and post-ERCP data were collected.RESULTS The study population consisted of 996 patients.Their mean age at presentation was 58.42(± 14.72) years,and there were 454 male and 442 female patients.Overall,PEP occurred in 102(10.2%) patients of the study population; eighty(78.4%) cases were of mild to moderate degree,while severe pancreatitis occurred in 22(21.6%) patients.No hospital mortality was reported for any of PEP patients during the study duration.Age less than 35 years(P = 0.001,OR = 0.035),narrower common bile duct(CBD) diameter(P = 0.0001) and increased number of pancreatic cannulations(P = 0.0001) were independent risk factors for the occurrence of PEP.CONCLUSION PEP is the most frequent and devastating complication after ERCP.Age less than 35 years,narrower median CBD diameter and increased number of pancreaticcannulations are independent risk factors for the occurrence of PEP.Patients with these risk factors are candidates for prophylactic and preventive measures against PEP. | Ayman El Nakeeb Ehab El Hanafy Tarek Salah Ehab Atef Hosam Hamed Ahmad M Sultan Emad Hamdy Mohamed Said Ahmed A El Geidie Tharwat Kandil Mohamed El Shobari Gamal El Ebidy | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，19： | 10 |
| 4 | Intraoperative endoscopic retrograde cholangiopancreatography: A useful tool in the hands of the hepatobiliary surgeon显示文摘AIM: To evaluate the efficacy of intraoperative endoscopic retrograde cholangio-pancreatography(ERCP) combined with laparoscopic cholecystectomy(LC) forpatients with gall bladder stones(GS) and common bile duct stones(CBDS).METHODS: Patients treated for GS with CBDS were included. LC and intraoperative transcystic cholangiogram(TCC) were performed in most of the cases. Intraoperative ERCP was done for cases with proven CBDS.RESULTS: Eighty patients who had GS with CBDS were included. LC was successful in all cases. Intraoperative TCC revealed passed CBD stones in 4 cases so intraoperative ERCP was performed only in 76 patients. Intraoperative ERCP showed dilated CBD with stones in 64 cases(84.2%) where removal of stones were successful; passed stones in 6 cases(7.9%); short lower end stricture with small stones present in two cases(2.6%) which were treated by removal of stones with stent insertion; long stricture lower 1/3 CBD in one case(1.3%) which was treated by open hepaticojejunostomy; and one case(1.3%) was proved to be ampullary carcinoma and whipple's operation was scheduled. CONCLUSION: The hepatobiliary surgeon should be trained on ERCP as the third hand to expand his field of therapeutic options. | Ayman El Nakeeb Ahmad M Sultan Emad Hamdy Ehab El Hanafy Ehab Atef Tarek Salah Ahmed A El Geidie Tharwat Kandil Mohamed El Shobari Gamal El Ebidy | 2015 | World Journal of Gastroenterology2015，21，2： | 6 |
| 5 | SMILE intraoperative complications: incidence and management显示文摘AIM: To report the intraoperative complications associated with small incision lenticule extraction(SMILE) and their management. METHODS: This was a retrospective consecutive interventional clinical study, carried out on patients with myopia and myopic astigmatism, who underwent SMILE procedure. Type of intraoperative complications and their management were recorded. RESULTS: Our study comprised 282 eyes of 141 patients who were enrolled for SMILE surgeries. The intraoperative complications included lost vacuum(18 eyes, 6.38%), treatment decentration(6 eyes, 2.12%), wound bleeding(21 eyes, 7.45%), incomplete bubble separation(black islands)(3 eyes, 1.06%), the epithelial defects(15 eyes, 5.32%). Incision tear(27 eyes, 9.57%), lenticule adherence to the cap(6 eyes, 2.12%), and cap perforation occurred in 2 eyes(0.7%). CONCLUSION: Although SMILE is a promising technique for the correction of myopia and myopic astigmatism with predictable, efficient, safe refractive and visual outcomes, complications can occur. However, most of them are related to inexperience and are included in the learning curve of the technique. More studies with a bigger number of eyes are required to efficiently evaluate the intraoperative complications and standardize their management strategies. | Abdelmonem M Hamed Mohamed Amin Heikal Tarek T.Soliman Ahmed Daifalla Khaled E Said-Ahmed | 2019 | International Journal of Ophthalmology(English edition)2019，12，2： | 4 |
| 6 | Impact of cirrhosis on surgical outcome after pancreaticoduodenectomy显示文摘AIM:To elucidate surgical outcomes of pancreaticoduodenectomy(PD)in patients with liver cirrhosis.METHODS:We studied retrospectively all patients who underwent PD in our centre between January 2002and December 2011.Group A comprised patients with cirrhotic livers,and Group B comprised patients with non-cirrhotic livers.The cirrhotic patients had ChildPugh classes A and B(patient’s score less than 8).Preoperative demographic data,intra-operative data and postoperative details were collected.The primary outcome measure was hospital mortality rate.Secondary outcomes analysed included duration of the operation,postoperative hospital stay,postoperative morbidity and survival rate.RESULTS:Only 67/442 patients(15.2%)had cirrhotic livers.Intraoperative blood loss and blood transfusion were significantly higher in group A(P=0.0001).The mean surgical time in group A was significantly longer than that in group B(P=0.0001).Wound complications(P=0.02),internal haemorrhage(P=0.05),pancreatic fistula(P=0.02)and hospital mortality(P=0.0001)were significantly higher in the cirrhotic patients.Postoperative stay was significantly longer in group A(P=0.03).The median survival was 19 mo in group A and 24 mo in group B.Portal hypertension(PHT)was present in 16/67 cases of cirrhosis(23.9%).The intraoperative blood loss and blood transfusion were significantly higher in patients with PHT(P=0.001).Postoperative morbidity(0.07)and hospital mortality(P=0.007)were higher in cirrhotic patients with PHT.CONCLUSION:Patients with periampullary tumours and well-compensated chronic liver disease should be routinely considered for PD at high volume centres with available expertise to manage liver cirrhosis.PD is associated with an increased risk of postoperative morbidity in patients with liver cirrhosis;therefore,it is only recommended in patients with Child A cirrhosis without portal hypertension. | Ayman El Nakeeb Ahmad M Sultan Tarek Salah Mohamed El Hemaly Emad Hamdy Ali Salem Ahmed Moneer Rami Said Ahmed AbuEleneen Mostafa Abu Zeid Talaat Abdallah Mohamed Abdel Wahab | 2013 | World Journal of Gastroenterology2013，19，41： | 3 |

| 9 | Melatonin and/or rowatinex attenuate streptozotocin-induced diabetic renal injury in rats显示文摘The study aimed to explore the prophylactic effect of melatonin, rowatinex; a naturally occurring renal drug, and its combination on diabetic nephropathy in type 2 diabetic rats. Diabetes was induced by intraperitoneal injection of a single dose of streptozotocin(50 mg/g body weight). Three days before diabetes induction, rats were daily treated with melatonin, rowatinex and their combination continuously for 8 weeks. Evaluation was done through measuring blood urea nitrogen(BUN), serum uric acid, serum creatinine, urine creatinine, creatinine clearance, nitric oxide(NO), malondialdehyde(MDA), superoxide dismutase(SOD), glutathione(GSH), total antioxidant capacity(TAC),kidney injury molecule-1(KIM-1), heat shock protein-70(HSP-70), caspase-3, transforming growth factor β1(TGFβ1), DNA degradation by the comet assay and total protein contents. Histopathologic study was also done for the kidney and the pancreas. Drastic changes in all measured parameters of the diabetic rats were observed. Treatment with melatonin and rowatinex showed amelioration to variable degrees. In conclusion, melatonin showed the most potent effect on protecting rats from deleterious action of diabetic nephropathy followed by its combination with rowatinex. | Tarek K Motawi Samia A Ahmed Manal A Hamed Shohda A El-Maraghy Wessam M Aziz | 2019 | The Journal of Biomedical Research2019，33，2： | 2 |
