| 1 | Cystic meconium peritonitis with jejunoileal atresia:Is it associated with unfavorable outcome?显示文摘AIM To compare the outcome between patients with jejunoileal atresia(JIA) associated with cystic meconium peritonitis(CMP) and patients with isolated JIA(JIA without CMP).METHODS A retrospective study was conducted for all neonates with JIA operated in our institute from January 2005 to January 2016.Demographics including the gestation age,sex,birth weight,age at operation,the presence of associated syndrome was recorded.Clinical outcome including the type of operation performed,operative time,the need for reoperation and mortality were studied.The demographics and the outcome between the 2 groups were compared.RESULTS During the study period,53 neonates had JIA underwent operation in our institute.Seventeen neonates(32%) were associated with CMP.There was no statistical difference on the demographics in the two groups.Patients with CMP had earlier operation than patients with isolated JIA(mean 1.4 d vs 3 d,P = 0.038).Primaryanastomosis was performed in 16 patients(94%) with CMP and 30 patients(83%) with isolated JIA(P = 0.269).Patients with CMP had longer operation(mean 190 min vs 154 min,P = 0.004).There were no statistical difference the need for reoperation(3 vs 6,P = 0.606) and mortality(2 vs 1,P = 0.269) between the two groups.CONCLUSION Primary intestinal anastomosis can be performed in94% of patients with JIA associated with CMP.Although patients with CMP had longer operative time,the mortality and reoperation rates were low and were comparable to patients with isolated JIA. | Kin Wai Edwin Chan Kim Hung Lee Hei Yi Vicky Wong Siu Yan Bess Tsui Yuen Shan Wong Kit Yi Kristine Pang Jennifer Wai Cheung Mou Yuk Him Tam | 2017 | World Journal of Clinical Pediatrics2017，6，1： | 3 |
| 2 | Laparoscopic excision of Meckel's diverticulum in children:What is the current evidence?显示文摘Complications aroused from Meckel's diverticulum tend to developed in children.Children presented with abdominal pain,intestinal obstruction,intussusception or gastrointestinal bleeding may actually suffered from complicated Meckel's diverticulum.With the advancement of minimally invasive surgery(MIS) in children,the use of laparoscopy in the diagnosis and subsequent laparoscopic excision of Meckel's diverticulum has gained popularity.Recently,single incision laparoscopic surgery(SILS) has emerged as a new technique in minimally invasive surgery.This review offers the overview in the development of MIS in the management of children suffered from Meckel's diverticulum.The current evidence in different laparoscopic techniques,including conventional laparoscopy,SILS,the use of special laparoscopic instruments,intracorporeal diverticulectomy and extracorporeal diverticulectomy in the management of Meckel's diverticulum in children were revealed. | Kin Wai Edwin Chan Kim Hung Lee Hei Yi Vicky Wong Siu Yan Bess Tsui Yuen Shan Wong Kit Yi Kristine Pang Jennifer Wai Cheung Mou Yuk Him Tam | 2014 | World Journal of Gastroenterology2014，20，41： | 2 |
| 3 | Use of laparoscopy as the initial surgical approach of impalpable testes:10-year experience显示文摘AIM: To review the experience in the management of impalpable testes using laparoscopy as the initial approach and the need for inguinal exploration.METHODS: From January 2004 to June 2014, 339 patients with undescended testes underwent operation in our institute. Fifty patients(15%) had impalpable testes. All children with impalpable testes underwent initial laparoscopy. A retrospective review was conducted on this group of patients and the outcome was analyzed.RESULTS: Forty children had unilateral impalpable testis. Ten children had bilateral impalpable testes. Thirty-one children(78%) in the unilateral group underwent subsequent inguinal exploration while 4 children(40%) in the bilateral group underwent inguinal exploration(P < 0.05). Orchidopexy was performed in 16 children(40%) in the unilateral group and 9 children(90%) in the bilateral group(P < 0.05). Regarding the 24 children with unilateral impalpable testis and underwent orchidectomy for testicular nubbin(n = 19) or atrophic testes(n = 2) or has vanishing testes(n = 3); contralateral testicular hypertrophy was noticed in 10(41%). No intra-operative complication was encountered. Two children after staged Fowler-Stephensprocedure and 1 child after inguinal orchidopexy had atrophic testes.CONCLUSION: The use of laparoscopy in children with impalpable testes is a safe procedure and can guide the need for subsequent inguinal exploration. Children with unilateral impalpable testis were associated with an increased need for inguinal exploration after laparoscopy. Orchidopexies could be performed successfully in 90% of children with bilateral impalpable testes. | Kin Wai Edwin Chan Kim Hung Lee Hei Yi Vicky Wong Siu Yan Bess Tsui Yuen Shan Wong Kit Yi Kristine Pang Jennifer Wai Cheung Mou Yuk Him Tam | 2015 | World Journal of Clinical Pediatrics2015，4，4： | 2 |
| 4 | Resource Allocation Based on User Pairing and Subcarrier Matching for Downlink Non-Orthogonal Multiple Access Networks显示文摘The traditional orthogonal multiple access(OMA)is unable to satisfy the needs of large number of smart devices.To increase the transmission rate in the limited spectrum resource,implementation of both non-orthogonal multiple access(NOMA)and successive interference cancelation(SIC)is essential.In this paper,an optimal resource allocation algorithm in NOMA is proposed to maximize the total system rate in a multi-sector multi-subcarrier relay-assisted communication network.Since the original problem is a non-convex problem with mixed integer programming which is non-deterministic polynomial-time(NP)-hard,a three-step solution is proposed to solve the primal problem.Firstly,we determine the optimal power allocation of the outer users by using the approach of monotonic discrimination,and then the optimal user pairing is determined.Secondly,the successive convex approximation(SCA)method is introduced to transform the non-convex problem involving central users into convex one,and the Lagrangian dual method is used to determine the optimal solution.Finally,the standard Hungarian algorithm is utilized to determine the optimal subcarrier matching.The simulation results show that resource allocation algorithm is able to meet the user performance requirements with NOMA,and the total system rate is improved compared to the existing algorithms. | Zhixin Liu Changjian Liang Yazhou Yuan Kit Yan Chan Xinping Guan | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，3： | 1 |

| 10 | Multinational survey on the preferred approach to management of Barrett’s esophagus in the Asia-Pacific region显示文摘BACKGROUND Major societies provide differing guidance on management of Barrett’s esophagus(BE),making standardization challenging.AIM To evaluate the preferred diagnosis and management practices of BE among Asian endoscopists.METHODS Endoscopists from across Asia were invited to participate in an online questionnaire comprising eleven questions regarding diagnosis,surveillance and management of BE.RESULTS Five hundred sixty-nine of 1016(56.0%)respondents completed the survey,with most respondents from Japan(n=310,54.5%)and China(n=129,22.7%).Overall,the preferred endoscopic landmark of the esophagogastric junction was squamocolumnar junction(42.0%).Distal palisade vessels was preferred in Japan(59.0%vs 10.0%,P<0.001)while outside Japan,squamo-columnar junction was preferred(59.5%vs 27.4%,P<0.001).Only 16.3%of respondents used Prague C and M criteria all the time.It was never used by 46.1%of Japanese,whereas 84.2%outside Japan,endoscopists used it to varying extents(P<0.001).Most Asian endoscopists(70.8%)would survey long-segment BE without dysplasia every two years.Adherence to Seattle protocol was poor with only 6.3%always performing it.73.2%of Japanese never did it,compared to 19.3%outside Japan(P<0.001).The most preferred(74.0%)treatment of non-dysplastic BE was proton pump inhibitor only when the patient was symptomatic or had esophagitis.For BE with low-grade dysplasia,6-monthly surveillance was preferred in 61.9%within Japan vs 47.9%outside Japan(P<0.001).CONCLUSION Diagnosis and management of BE varied within Asia,with stark contrast between Japan and outside Japan.Most Asian endoscopists chose squamo-columnar junction to be the landmark for esophagogastric junction,which is incorrect.Most also did not consistently use Prague criteria,and Seattle protocol.Lack of standardization,education and research are possible reasons. | Guan Sen Kew Alex Yu Sen Soh Yeong Yeh Lee Takuji Gotoda Yan-Qing Li Yan Zhang Yiong Huak Chan Kewin Tien Ho Siah Daniel Tong Simon Ying Kit Law Andrew Ruszkiewicz Ping-Huei Tseng Yi-Chia Lee Chi-Yang Chang Duc Trong Quach Chika Kusano Shobna Bhatia Justin Che-Yuen Wu Rajvinder Singh Prateek Sharma Khek-Yu Ho | 2021 | World Journal of Gastrointestinal Oncology2021，13，4： | 0 |
| 11 | Efficacy of vasopressin, steroid, and epinephrine protocol for in-hospital cardiac arrest resuscitation: a systematic review and meta-analysis of randomized controlled trials with trial sequential analysis显示文摘OBJECTIVES To assess the effect of vasopressin,steroid and epinephrine(VSE)combination therapy on return of spontan-eous circulation(ROSC)after in-hospital cardiac arrest(IHCA),and test the conclusiveness of evidence using trial sequential ana-lysis(TSA).METHODS The systematic search included PubMed,EMBASE,Scopus,and Cochrane Central Register of Controlled Trials.Randomized controlled trials(RCTs)that included adult patients with IHCA,with at least one group receiving combined VSE therapy were selected.Data was extracted independently by two reviewers.The main outcome of interest was ROSC.Other out-comes included survival to hospital discharge or survival to 30 and 90 days,with good neurological outcomes.RESULTS We included a total of three RCTs(n=869).Results showed that VSE combination therapy increased ROSC(risk ra-tio=1.41;95%CI:1.25-1.59)as compared to placebo.TSA demonstrated that the existing evidence is conclusive.This was also validated by the alpha-spending adjusted relative risk(1.32[1.16,1.49],P<0.0001).Other outcomes could not be meta-analysed due to differences in timeframe in the included studies.CONCLUSIONS VSE combination therapy administered in cardiopulmonary resuscitation led to improved rates of ROSC.Fu-ture trials of VSE therapy should evaluate survival to hospital discharge,neurological function and long-term survival. | Danish Iltaf Satti Yan Hiu Athena Lee Keith Sai Kit Leung Jeremy Man Ho Hui Thompson Ka Ming Kot Arslan Babar Gauranga Mahalwar Abraham KC Wai Tong Liu Leonardo Roever Gary Tse Jeffrey Shi Kai Chan International Health Informatics Study(IHIS)Network | 2022 | Journal of Geriatric Cardiology2022，19，9： | 0 |
